    Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care. Dental caries is an unevenly distributed, preventable disease with considerable economic and quality-of-life burdens. The daily use of fluoride toothpaste is seen as the main reason for the overall decline of caries worldwide over recent decades. This Primer aims to provide a global overview of caries, acknowledging the historical era dominated by restoration of tooth decay by surgical means, but focuses on current, progressive and more holistic long-term, patient-centred, tooth-preserving preventive care.

    Full Text Available Dental caries is one of the most common diseases in humans. In modern times, it has reached epidemic proportions. Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. The time factor is important for the development and progression of dental caries. A wide group of microorganisms are identified from carious lesions of which S. mutans , Lactobacillus acidophilus , and Actinomyces viscosus are the main pathogenic species involved in the initiation and development of dental caries. In India, surveys done on school children showed caries prevalence of approximately 58%. Surveys among the U.S. population showed an incidence of 45.3% in children and 93.8% in adults with either past or present coronal caries. Huge amounts of money and time are spent in treating dental caries. Hence, the prevention and control of dental caries is the main aim of public health, eventually the ultimate objective of public health is the elimination of the disease itself. Recently, dental caries vaccines have been developed for the prevention of dental caries. These dental caries vaccines are still in the early stages.

    Dental caries is one of the most common infectious diseases. Of the oral bacteria, mutans streptococci, such as Streptococcus mutans and S. sobrinus, are considered to be causative agents of dental caries in humans. There have been numerous studies of the immunology of mutans streptococci. To control dental caries, dental caries vaccines have been produced using various cell-surface antigens of these organisms. Progress in recombinant DNA technology and peptide synthesis has been applied to the development of recombinant and synthetic peptide vaccines to control dental caries. Significant protective effects against dental caries have been shown in experimental animals, such as mice, rats and monkeys, which have been subcutaneously, orally, or intranasally immunized with these antigens. Only a few studies, however, have examined the efficacy of dental caries vaccines in humans. Recently, local passive immunization using murine monoclonal antibodies, transgenic plant antibodies, egg-yolk antibodies, and bovine milk antibodies to antigens of mutans streptococci have been used to control the colonization of the organisms and the induction of dental caries in human. Such immunization procedures may be a safer approach for controlling human dental caries than active immunization.

    Full Text Available La mínima intervención en cariología ha sido definida como la filosofía de cuidados estomatológicos que se encarga del tratamiento de la primera aparición, la detección temprana y el tratamiento de la caries dental. Una de las técnicas para el tratamiento temprano y detención de lesiones incipientes es la infiltración de resina. El objetivo es mostrar la utilidad de las resinas fluidas para la infiltración de un primer y segundo molar inferior permanentes con una lesión incipiente de caries dental. Se trata de un paciente masculino de 17 años de edad sin antecedentes patológicos, que acude a consulta estomatológica. En hemiarcada inferior izquierda se observaron manchas en forma de punto de color marrón oscuro cerca de la fosita central y en la estría vestibular del 36 y 37 respectivamente, que no presentaban más de 1 mm de profundidad. Se diagnosticaron lesiones de caries dental incipiente y se decidió realizar una infiltración con resina compuesta de baja viscosidad o fluida en consulta única. El uso de resinas compuestas fluidas es beneficioso en la infiltración de lesiones cariosas incipientes de esmalte, pues evita su propagación y sella las brechas de esmalte afectado. Es una técnica de mínima intervención en cariología, que propicia una solución inmediata para estos procesos y mayor sencillez para la solución de la enfermedad caries dental al equilibrar las expectativas estéticas y de mantenimiento de las estructuras dentarias sanas.

  6. Dental reductions and dental caries.

    Anderson, D L; Popovich, F

    1977-11-01

    Although first permanent molar hypoconulid absence, third molar agenesis, and small tooth size are all part of evolutionary trend of dental retardation, each bears a different relationship to dental caries. Caries prevalence in the maxillary and mandibular permanent first molars of the Burlington Research Centre serial experimental group at age 16 years was less in the children whose first molars were missing the hypoconulid. Conversely, caries prevalence in mandibular first molars was greater in the children who had agenesis of third molars. The extraction of first molars due to caries was more frequent in children with agenesis of third molars, less frequent in those with absence of hypoconulids of the first molars and unrelated to tooth size. Caries prevalence was less in small teeth, and occurred least in the small mandibular first molars with four cusps. Whereas this is in harmony with the hypothesis that evolutionary dental reductions resulted from the pressure of caries, the increased prevalence of caries and extractions coinciding with third molar agenesis does not support this view. In addition, agenesis of hypoconulids and agenesis of third molars were related to changes in structures unrelated to caries.

    Full Text Available Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.

    Keyes, Paul H; Rams, Thomas E

    An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

    Dental carie is the most common infectious disease in humans. In the past decades, it has been described as a multifactorial condition, where diet and the immune response are main factors for the establishment of the disease. The authors approach the formation of the bacterian biofilm, the host's immune response, according to its maturation and deficiencies, and the current research to find a preventive intervention for this disease.

    Full Text Available Introducción: La caries dental es la enfermedad crónica más prevalente en el mundo, y en Colombia, como en otros países, es considerada como un problema de salud pública. Es una enfermedad compleja, dinámica, y para su desarrollo intervienen muchos factores; la dieta rica en carbohidratos, es uno de los más significativos. La sacarosa se ha relacionado con problemas de salud como la caries, por ello, es deseable su reemplazo por edulcorantes con menos efectos adversos, y que aporten beneficios a la salud general y bucal de los humanos. Objetivo: fundamentar, si la Stevia, podría ser considerada como un coadyuvante en la prevención y control de la caries dental. Metodología: se realizó una búsqueda de literatura utilizando las bases de datos: Pubmed, Academic Search Complete, Embase, ScienceDirect, y el motor de búsqueda Google académico, mediante los términos MESH: “Dental Caries”, “Stevia”, “Anti-bacterial Agents”, “Sweetening Agents” y palabras clave en español: “Caries dental”, “Edulcorantes”, “Stevia”. Resultados: Los estudios revisados in vivo e in vitro mostraron: actividad antibacteriana de extractos de Stevia sobre microorganismos relacionados con caries dental, bajo potencial acidogénico y disminución en la formación de biopelícula dental, debido a la disminución de la hidrofobicidad celular e inhibición de la síntesis de polisacáridos extracelulares. Conclusiones: Aunque la evidencia científica aún es insuficiente, la Stevia rebaudiana es una adecuada candidata a reemplazar la sacarosa y puede considerarse como coadyuvante potencial para disminuir los niveles de caries dental, sin embargo, se recomienda realizar más estudios controlados y aleatorizados para que dicho rol se confirme.

  13. Caries detection in dental radiographs

    Caries, or the decay of teeth are difficult to automatically detect in dental radiographs because of the small area of the image that is occupied by the decay. Images of dental radiographs has distinct regions of homogeneous gray levels, and therefore naturally lead to a segmentation based automatic caries detection algorithm. This paper describes a method for caries detection based on a multiclass, area independent thresholding and segmenting scheme. This multiclass thresholding algorithm is an extension of the uniform error threshold, an area independent, distribution free thresholding method used for images of only two classes of objects. The authors first consider the problem of caries detection and the image features that characterize the presence of caries. Next, the uniform error threshold is reviewed, and the general multiclass uniform error threshold algorithm is presented. This algorithm is used to automatically detect caries in dental radiographs

    Promotion of sound dietary practices is an essential component of caries management, along with fluoride exposure and oral hygiene practices. Scientific discoveries have lead to better understanding of the caries process, the ever-expanding food supply, and the interaction between the two. Fermentable carbohydrates interact dynamically with oral bacteria and saliva, and these foods will continue to be a major part of a healthful diet. Dental health professionals can serve their patients and the public by providing comprehensive oral health care and by promoting lifestyle behaviors to improve oral and general health within the time constraints of their practice. Dietary advice given should not contradict general health principles when providing practical guidance to reduce caries risk. The following principles should guide messages: * Encourage balanced diets based on moderation and variety as depicted by the Food Guide Pyramid and the Dietary Guidelines for Americans to provide a sound approach. Avoid references to "bad" foods and focus on "good" diets that include a variety of foods. * Give examples of how combining and sequencing foods can enhance mastication, saliva production, and oral clearance at each eating occasion. Combining dairy foods with sugary foods, raw foods with cooked, and protein-rich foods with acidogenic foods are all good examples. Suggest that eating and drinking be followed by cariostatic foods such as xylitol chewing gum. * Drink water to satisfy thirst and hydration needs as often as possible. Restrict consumption of sweetened beverages to meal and snack times when they can be combined with other cariostatic foods. * When a patient reports excessive dietary intake of a fermentable carbohydrate to the point of displacing other important foods in the diet, identify alternatives that will help the patient maintain or achieve a healthy body weight, oral health status, and a nutrient-dense intake.

  16. Health promotion and dental caries

    Full Text Available The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene, among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

    As a highly prevalent multifactorial disease, dental caries afflicts a large proportion of the world's population. As teeth are constantly bathed in saliva, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of dental caries. Various inorganic (water and electrolytes) and organic (proteins and peptides) components may protect teeth from dental caries. This occurs via several functions, such as clearance of food debris and sugar, aggregation and elimination of microorganisms, buffering actions to neutralize acid, maintaining supersaturation with respect to tooth mineral, participation in formation of the acquired pellicle and antimicrobial defense. Modest evidence is available on the associations between dental caries and several salivary parameters, including flow rate, buffering capacity and abundance of mutans streptococci. Despite some controversial findings, the main body of the literature supports an elevated caries prevalence and/or incidence among people with a pathologically low saliva flow rate, compromised buffering capacity and early colonization or high titer of mutans streptococci in saliva. The evidence remains weak and/or inconsistent on the association between dental caries and other saliva parameters, such as other possible cariogenic species (Lactobacillus spp., Streptococcus sanguis group, Streptococcus salivarius, Actinomyces spp. and Candida albicans), diversity of saliva microbiomes, inorganic and organic constituents (electrolytes, immunoglobulins, other proteins and peptides) and some functional properties (sugar clearance rate, etc.). The complex interactions between salivary components and functions suggest that saliva has to be considered in its entirety to account for its total effects on teeth. © 2015 John Wiley & Sons A/S.

    Lactobacilli have been associated with dental caries for over a century. Here, we review the pertinent literature along with findings from our own study to formulate a working hypothesis about the natural history and role of lactobacilli. Unlike most indigenous microbes that stably colonize a host, lactobacilli appear to be planktonic, opportunistic settlers that can gather and multiply only in certain restrictive niches of the host, at least within the oral cavity. We postulate that the following essential requirements are necessary for sustained colonization of lactobacilli in humans: 1) a stagnant, retentive niche that is mostly anaerobic; 2) a low pH milieu; and 3) ready access to carbohydrates. Three sites on the human body meet these specifications: caries lesions, the stomach, and the vagina. Only a handful of Lactobacillus species is found in caries lesions, but they are largely absent in caries-free children. Lactobacilli present in caries lesions represent both a major contributor to caries progression and a major reservoir to the gastrointestinal (GI) tract. We extend the assertion from other investigators that lactobacilli found in the GI tract originate in the oral cavity by proposing that lactobacilli in the oral cavity arise from caries lesions. This, in turn, leads us to reflect on the health implications of the lactobacilli in the mouth and downstream GI and to ponder whether these or any of the Lactobacillus species are truly indigenous to the human GI tract or the oral cavity.

    Background: Dental caries is an infectious disease of microbiologic origin resulting in destruction and loss of tooth structure and is related to every speciality of dentistry. Many studies have been carried out to identify the causative factors, methods of prevention, and treatment of dental caries. Ameloglyphics is the study of enamel rod end patterns. These patterns have been found to be unique to individual teeth of the same individual and also to different individuals. A possible correlation between the type of enamel rod end pattern and the occurrence of dental caries might help in predicting caries susceptibility of an individual and implementation of preventive measures. This is a simple and easy method cutting short elaborate methods currently in use and can be invaluable in caries prevention. Objective: This study is aimed at ascertaining the possibility of a correlation between enamel rod end patterns and occurrence of dental caries, which might help in identifying predisposition to dental caries. Materials and Methods: Thirty carious and 30 noncarious teeth were used to obtain enamel rod end patterns. Occurrence of any particular pattern in either of the study groups, which might affect the predisposition of teeth to dental caries was analyzed. Results: No particular rod end pattern was found in teeth affected by dental caries. Also, no particular pattern was found to be unique to teeth not affected by dental caries. PMID:24250075

  5. The relationship between diet and Dental Caries

    Dental caries is a disease of multifactorial etiology and results from a complex interaction between both cariogenic and protective influences acting on the teeth. Though diet plays a major role in the causation of dental caries it has been a common mistake to over-simplify the relationship. Dietary manipulation is also extremely difficult to achieve thus limiting its role in the prevention of caries. Accordingly, alternative preventive measures such as the use of fissure sealants and fluoride which enhance the resistance of the host to disease and are of proven efficacy are more likely to be successful in the control and prevention of dental caries.

    Dental caries is an irreversible microbial disease of the calcified tissues of the teeth and it has a multifactorial origin. In India, the dental caries prevalence in 35-44 year olds was reported to be 80-95% in a DCI survey. Among the elderly in the 65-74 years age group, the DCI survey reported the caries prevalence to be about 70%, while the present survey reported it to be 51- 95% in various states. Surveys which were done on school children in India showed a carie prevalence of approximately 58%.Among the U.S. population, a survey showed an incidence of 93.8% in adults with either past or present coronal caries and an incidence of 45.3% in children 23. In countries like Brazil and China, it is reaching epidemic proportions. Thus, more effective public-health measures are needed to combat dental caries. Mutans streptococci is one of the main microorganisms which are associated with the aetiology of dental caries. Preclinical studies of immunological interventions have shown that the disease can be interrupted. Clinical trials have indicated that a mucosal immune response to Streptococcus mutans crucial antigens can influence the pathogenesis of dental caries. The dental caries vaccine, when it is used in appropriate individuals at the appropriate time, can reduce the reemergence of the disease.

    The poor oral health of nursing home residents is the cause of substantial morbidity and has major implications relating to health care policy. The aim of this study was to measure dental caries experience in Australians living in nursing homes, and investigate associations with resident characteristics. Clinical dental examinations were conducted on 243 residents from 19 nursing homes in Melbourne. Resident characteristics were obtained from nursing home records and interviews with residents, family and nursing home staff. Two dental examiners assessed coronal and root dental caries using standard ICDAS-II criteria. Residents were elderly, medically compromised and functionally impaired. Most required assistance with oral hygiene and professional dental care was rarely utilized. Residents had high rates of coronal and root caries, with a mean 2.8 teeth with untreated coronal caries and 5.0 root surfaces with untreated root caries. Functional impairment and irregular professional dental care were associated with higher rates of untreated tooth decay. There were no significant associations with medical conditions or the number of medications taken. Nursing home residents have high levels of untreated coronal and root caries, particularly those with high needs due to functional impairment but poor access to professional services. © 2014 Australian Dental Association.

    To assess individuals' perception of dental caries, in order to explain how illness representations might influence their coping with the disease. Cross-sectional questionnaire study. 520 consecutive patients (aged ≥18 years) of the General Dentistry Clinic at Universidad Cooperativa de Colombia, Pasto, Colombia who had experienced dental caries. Illness perception of dental caries was assessed using the Illness Perception Questionnaire Revised (IPQ-R). The most frequent self-reported symptoms associated with dental caries were "toothache" (56.2%), "tooth sensitivity" (53.8%) and "mild to sharp pain when eating or drinking" (51.2%). The dimensions of illness perception were related to socio-economic status (SES). Symptoms of "loose or separating teeth" and "pus in your tooth" were associated with dental caries by low SES participants, while "bleeding while brushing, flossing or eating hard food" and "mild to sharp pain when eating or drinking something sweet, hot or cold" were related more to higher SES. Perceptions of caries were related to socioeconomic status. Interventions to promote health literacy in order to improve the capacity to obtain, process and understand basic oral health information could increase an early detection of caries.

    Dental caries is a disease induced by dental plaque, which can be described as a community of microorganisms (biofilm). Because of genetic and environmental factors a number of changes in the oral microbiome takes place; in case of commensalism and mutualism between biofilm microorganisms and the host, homeostasis in oral microbiome is maintained. However, when a risk factor occurs parasitic relationship starts prevailing and activity of the pathogenic cariogenic microorganisms increases leading to a dental caries. According to the newest technologies of molecular microbiology new cariogenic microorganisms species have been determined. Each individual's oral microbiome is as unique as his/her immune system; therefore, commonly taken caries prevention measures cannot be of the same effectiveness for all individuals. Each person has his own caries risk which is determined by the oral microbiome and immune system influenced by the environmental and genetic factors. Early caries diagnostic, risk assessment and individualized caries prevention plan will allow us to control the disease and achieve a desirable effect. For the dentist the most important thing is not to treat the consequences of the disease - cavities - but be aware of the dental caries as a biological phenomenon.

    Prevalence and distribution of dental caries in medieval Korean society were evaluated. Two thousand and nine hundred teeth samples of 126 individuals collected from 16th to 18th century Korean tombs. Preservation status of sample was good. The prevalence of ante- and postmortem tooth loss was 4.4% and 14.2%, respectively. The total caries prevalence was 3.9%. The tooth surface most frequently affected by dental caries was occlusal (4.5%), followed by approximal (2.1%), buccal (1.5%), and lingual (1.1%) surfaces. The prevalence of dental caries in Joseon Dynasty skeleton collection was lower than have been found in other collections of similar chronology. The low consumption of refined sugar in medieval Korean society might be a possible explanation, though the technical limitations inherent in such comparison studies preclude definitive conclusions. 2010 Elsevier Ltd.

    Dermatoglyphics can prove to be an extremely useful tool for preliminary investigations in conditions with a suspected genetic base. Since caries is a multifactorial disease with the influence of genetic pattern, early prediction for high-risk children can help in using effective and efficient caries preventive measures that are a part of the pedodontist arsenal. This study was done to determine the genetic aspect involved in the occurrence of dental caries through a cost-effective means, which can be used in field studies. 550 kindergarten school children in the age group 3-6 years were examined during a school examination camp. Of these, only 336 children were included in the study. They were divided into four groups as follows: caries-free males (df score=0), caries-free females, caries males (df score≥10), caries females. The handprints of each child were taken and the frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Separate df scores were recorded. SPSS software and test of proportions were used for the analysis. Handprints of caries-free children, especially females, showed maximum ulnar loops. The caries group showed maximum occurrence of whorls (r=2:1), which were more prevalent in females on the left hand 3rd digit than in males where the whorls were found on the right hand 3 rd digit, and also low total ridge count, especially in males.

    2006-06-01

    Full Text Available Abstract The number of new technologies emerging each year in the realm of dental caries management is growing at an exponential rate. Examining the patent literature, one can see that this growth rate will likely continue, with the outcome that dentistry will see an expanded growth in managing dental caries by risk assessment with medicinal therapeutic interventions. Restorative dentistry solutions, treating the results of dental caries, will continue to grow, while technologies to identify the caries process at its earliest stages will soon invade practices everywhere. The most interesting aspect of these changes will be how industry responds to the inexorable, yet slow change in dental professional demand for these new technologies, while trying to be the "first to market" within the various categories of this business opportunity. This paper will take a close look at how businesses with the core competence to be key players in this emerging growth category will assess the marketplace, and match up their business interests with the changing needs of the dental profession. The paper will also address the strategic planning and business processes that the dental industry will undertake to bring new technologies to market, and how these technologies will be positioned to health care professionals and consumers. The results of the key interactions between industry and the dental profession will determine the extent to which dental caries is managed as a disease, in addition to being managed by surgical restorative interventions.

    Dental caries affects the majority of the Danish population. Its aetiology is multi-factorial, but a pH-induced change in the homeostasis of the oral biofilm leading to overgrowth of acid-tolerating bacteria is a key event. A non-invasive concept for prevention and management is emerging based on the common risk factor approach. There is strong evidence that tooth brushing twice a day with fluoridated toothpaste is the most cost-effective way to prevent and control caries development. Physicians need to consider that a number of drugs may affect the saliva flow rate, which increases the caries risk.

    Saliva is one of the intraoral host factors that influence caries development. The authors conducted a study to investigate whether salivary characteristics are associated with recent dental caries experience. Dentist-investigators and dental staff members collected data pertaining to a two-year cumulative incidence of dental caries (previous 24 months) and salivary characteristics during baseline assessment in an ongoing longitudinal study. The systematic random sample consisted of patients (n = 1,763) visiting general dental practices (n = 63) within the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry (PRECEDENT). The authors estimated adjusted rate ratios (RRs) by using generalized estimating equations log-linear regression to relate salivary characteristics to coronal carious lesions into dentin. Low resting pH (≤ 6.0) in the overall sample and low stimulated salivary flow rate (≤ 0.6 milliliter/minute) in older adults (≥ 65 years old) were associated with increased dental caries (RR, 1.6; 95 percent confidence interval [CI], 1.1-2.2; RR, 2.4; 95 percent CI, 1.5-3.8, respectively). Low buffering capacity was associated with decreased dental caries in children and adolescents (RR, 0.3; 95 percent CI, 0.1-1.0; RR, 0.2; 95 percent CI, 0.1-0.7, respectively). A thick, sticky or frothy salivary consistency also was associated with decreased dental caries in adults (RR, 0.6; 95 percent CI, 0.4-1.0). Associations between other salivary characteristics and dental caries for the overall sample and within each age group were not statistically significant. Salivary characteristics were associated weakly with previous dental caries experience, but the authors did not find consistent trends among the three age groups. Different salivary characteristics were associated with an increased caries experience in older adults and a lowered caries experience in children and adolescents and adults. Practical Implications. Further investigations are

    The study sought to analyze the association between dental caries and obesity in Chinese children, and to investigate the protective and risk factors of dental caries. A total of 280 children aged 7-12 years voluntarily answered the caries examination and questionnaire. Caries was measured using the International Caries Detection and Assessment System. According to the Chinese body mass index, the participants were grouped overweight or normal-weight. The logistic regression model showed no correlation between dental caries and obesity. Drinking yogurt and chewing gum are protective factors, whereas oral breathing and genetic predisposition to caries are risk factors. Copyright © 2012 S. Karger AG, Basel.

    A dose-response relationship between toothbrushing frequency and the incidence of dental caries has not been confirmed. Furthermore, no longitudinal study about this relationship has considered dental caries experience at baseline, which is an important factor influencing the frequency of future caries. To elucidate the association between the incidence of dental caries and toothbrushing frequency after adjusting for dental caries experience at baseline in a Japanese population. The 92 recruits of the Japan Maritime Self-Defense Force in Kure, Japan, in 2011 were followed up for 3 years. They underwent oral examination at the annual checkups and answered questions about toothbrushing frequency. The multiple logistic regression analysis was used to analyze the incidence of dental caries and to identify independent effects of toothbrushing frequency and dental caries experience at baseline. Furthermore, the relative importance of the incidence of dental caries was investigated among other independent variables using the partial adjusted R² score. Logistic regression analysis showed that toothbrushing frequency alone did not influence the increment in decayed, missing, and filled teeth (DMFT). However, DMFT at baseline alone was associated with the increment in DMFT (crude odds ratio, OR, 1.20, 95% confidence interval, CI, 1.08,1.33). In the fully adjusted model, only DMFT at baseline was associated with the increment in DMFT (adjusted OR 1.23, 95%CI 1.09,1.38). After three years, the incidence of dental caries in young adult Japanese males was influenced by DMFT at baseline, rather than toothbrushing frequency. Copyright© 2017 Dennis Barber Ltd.

    For decades, visual, tactile and radiographic examinations have been the standard for diagnosing caries. Nonetheless, the extent of variation in the diagnosis of dental caries is substantial among dental practitioners using these traditional techniques. Therefore, a more reliable standard for detecting incipient caries would be desirable. Using photoacoustics, near-infrared (NIR) optical contrast between sound and carious dental tissues can be relatively easily and accurately detected at ultrasound resolution. In this paper, a pulsed laser (Nd:YAG, Quanta-Ray) was used to probe extracted human molars at different disease stages determined from periapical radiographs. Both fundamental (1064nm) and first harmonic (532nm) pulses (15ns pulse length, 100mJ at fundamental and 9mJ at first harmonic , 10Hz pulse repetition rate) were used to illuminate the occlusal surface of tooth samples placed in a water tank. The photoacoustic signal was recorded with an unfocused wideband single-element piezoelectric transducer (centered at 12 MHz, bandwidth 15 MHz) positioned at small angle (less than 30 degrees) to the laser beam close to the occlusal surface. At the fundamental wavelength, total photoacoustic energy increases from normal to incipient stage disease by as much as a factor of 10. Differences between photoacoustic energy at the fundamental and first harmonic wavelength further indicate spectral absorption changes of the underlying structure with disease progression. Using a focused laser beam, an extracted molar with suspected incipient caries was scanned along the occulusal surface to help localize the caries inside enamel and dentin. The significantly increasing photoacoustic signal at a specific scan line both at fundamental and first harmonic indicates the local development of the incipient caries. The photoacoustic results compare well with visual inspection after layer by layer dissection. Preliminary results demonstrate the feasibility of detecting incipient

    This cross-sectional study aimed to determine the association between dental caries and weight status, and between dental caries and physical activity in Brazilian schoolchildren aged 8 to 12 years. A multi-stage sample of children enrolled in 20 private and public schools in 2010 in Pelotas, Southern Brazil, were invited to participate in the study. Socioeconomic data were collected from parents, and data regarding children characteristics were collected from children using a questionnaire and anthropometric measures. The Body Mass Index was obtained, and children were classified as overweight/obese considering age and sex. Dental examinations were performed to assess the presence of gingival inflammation, dental caries prevalence (DMFT≥1) and dental caries experience (mean DMFT). Multivariate Poisson Regression was used to assess factors associated with dental caries prevalence and experience. A total of 1,210 children were included in the study. Dental caries prevalence was 32.4% (95% CI 29.7-35.2), while the mean DMFT was 0.64 (± SD 1.00). Children who practiced less than 300 minutes per week of physical activity and overweigh/obese children had lower prevalence of dental caries, while children with obesity or overweight presented lower dental caries experience. Obesity/overweight and physical activity level presented an inverse relationship with dental caries. Longitudinal studies investigating the complexity of this relationship are required.

Se propuso realizar un estudio para determinar la presencia de caries dental y algunos factores de riesgo asociados en el primer y tercer trimestre del embarazo, para detectar la aparición de lesiones cariosas nuevas y cambios relacionados con los factores de riesgo entre ambos trimestres. Se realizó un estudio descriptivo longitudinal desde diciembre de 2006 a febrero de 2008 en el municipio de Florida, Camagüey, Cuba. El universo de estudio estuvo constituido por 38 embarazadas y la muestra por 21, que fueron interrogadas y examinadas en ambos trimestres con el objetivo de determinar la presencia de caries y los factores de riesgo asociados como: higiene bucal deficiente, dieta cariogénica, pH salival bajo, ocurrencia de vómitos y embarazo previo. La información necesaria fue recogida en un formulario confeccionado al efecto. En el primer trimestre el 80,95 % estaban afectadas por caries dental y se observó aparición de lesiones nuevas en 6 embarazadas, en el tercer trimestre. Los factores de riesgo presentados con mayor frecuencia en el primer trimestre fueron la dieta cariogénica en el 66,66 % y la higiene bucal deficiente en el 47,61 % de las pacientes. Ninguna embarazada modificó la dieta durante el embarazo, sin embargo la higiene bucal deficiente persistió en el 14,28 %.

Veillonella sp. use lactic acid as the end product of S. mutans which cause the dental caries. The principle of probiotic therapy is the comensalism symbiosis found in oral cavity ecosystem. Veillonella sp could be added to anticipate the lactic acid which cause enamel demineralization. Hopefully dentist will apply probiotic therapy, so there will be more study of Veillonella sp. as probiotic material for dental caries prevention. Further research on Veillonella sp in probiotic therapy and Immunology need to be done to achieve the balance of ecosystem.

    Stevia is a natural, non-caloric sweetener of plant origin. The sweetening power of stevia is several hundred times larger than that of table sugar (sucrose). On the basis of available research, the European Food Safety Authority concluded that stevia is safe for human consumption. Since then, stevia has been approved as a sweetener for the European market. As a substitute for sucrose, stevia can contribute to a reduced caloric intake and can play a role in the prevention and/or treatment of metabolic disorders. In addition, stevia is non-cariogenic and is, moreover, affordable. Promoting the consumption of stevia can therefore be a preventive means of fighting dental caries.

    Significant differences between the optical spectra taken from sound regions of teeth and carious regions have been observed. These differences appear both in absorption and in laser induced fluorescence spectra. Excitation by the 488 nm line of an argon ion laser beam showed a peak in the emission intensity around 553 nm for the sound dental material while the emission peak from the carious region was red-shifted by approximately 40 nm. The relative absorption of carious region was significantly higher at 488 nm; however its fluorescence intensity peak was lower by an order of magnitude compared to the sound tooth. Implications of these results for a safe, reliable and early detection of dental caries are discussed.

    Full Text Available The widespread expansion of the sugar market drove dental caries prevalence to high levels in several regions of the world. On the other hand, the dissemination of fluoride use is one of the reasons for caries decline at the end of the 20th century. However, caries remains one of the most prevalent non-communicable chronic diseases in human beings, and an important cause of pain and dental loss, which lead to school and work absenteeism affecting individuals' daily activities and emotional stability. The decline in caries has important implications for research, human resources and oral healthcare. The aim of this study was to summarize the changes in dental caries occurrence in the population, and bring to light the latest research on the role of non-biological determinants in caries distribution.

    Current diagnostic techniques in dentistry rely predominantly on X-rays to monitor dental caries. Terahertz Pulsed Imaging (TPI) has great potential for medical applications since it is a nondestructive imaging method. It does not cause any ionization hazard on biological samples due to low energy of THz radiation. Even though it is strongly absorbed by water which exhibits very unique chemical and physical properties that contribute to strong interaction with THz radiation, teeth can still be investigated in three dimensions. Recent investigations suggest that this method can be used in the early identification of dental diseases and imperfections in the tooth structure without the hazards of using techniques which rely on x-rays. We constructed a continuous wave (CW) and time-domain reflection mode raster scan THz imaging system that enables us to investigate various teeth samples in two or three dimensions. The samples comprised of either slices of individual tooth samples or rows of teeth embedded in wax, and the imaging was done by scanning the sample across the focus of the THz beam. 2D images were generated by acquiring the intensity of the THz radiation at each pixel, while 3D images were generated by collecting the amplitude of the reflected signal at each pixel. After analyzing the measurements in both the spatial and frequency domains, the results suggest that the THz pulse is sensitive to variations in the structure of the samples that suggest that this method can be useful in detecting the presence of caries.

    Caries is caused when the pH at the tooth surface drops below 5.5. A miniaturized and autonomous pH monitoring nodes can be attached to the tooth surface, like a tooth jewel. This intelligent sensor includes three components: (a) digital micro pH meter, (b) power supply, (c) wireless communicating device. The micro pH meter facilitates long term tooth surface pH monitoring and providing real time feedback to the patients and dental experts. Power supply of this system will be microfabricated biocatalytic fuel cell (enzymatic micro-battery) using organic compounds (e.g. formate or glucose) as the fuel to generate electricity. When micro pH meter detects the pH lower than 5.5, wireless Bluetooth device sends a caution (e.g. "you are at risk of dental caries") to external monitoring equipment such as mobile phone or a hands-free heads. After reception of the caution, subjects should use routine brushing and flossing procedure or use a medicated chewing gum (e.g. chlorhexidine containing chewing gum) or rinse with a mouthwash.

    Full Text Available BACKGROUND: In Indonesia, the prevalence of dental caries is 85%–99% and 67.4% of males aged 15 years or older are current users of tobacco. The aim of this study was to examine the association between heavy smoking and severe dental caries. METHODS: The authors used secondary data from Basic Health Research 2007. Respondents were Indonesian males aged 45–54 years (n = 34 534. Decay, Missing, Filled Teeth (DMFT value was used to define severe dental caries with 31.4% of respondents having DMFT value ≥ 8, the cutoff point of severe dental caries in this study. In addition, the enumerators recorded socio-demographic characteristics (age, socio-economic status, education, and job, tooth brushing and smoking behavior of respondents. Chi-square test was used to compare the prevalence of severe dental caries between heavy smokers (defined as Brinkman Index or BI ≥ 400 and never smokers (BI = 0. The multivariable logistic regression model was used to estimate adjusted association between heavy smoking and dental caries severity. RESULTS: The prevalence of severe dental caries among never smokers, light smokers (BI 1-399 and heavy smokers was 24.9%, 32.5%, and 38.7% respectively (p < 0.005. Compared to never smokers, the adjusted ORs of having severe dental caries among light smokers and heavy smokers were 1.45 (95% CI: 1.37-1.53 and 1.70 (95% CI: 1.59 – 1.81, respectively. CONCLUSIONS: Smoking is a risk factor of severe dental caries in Indonesian men with dose-and-response association revealed between the exposure and the outcome. Indonesian dentists, individually and collectively, have to participate in smoking prevention and control more actively.

  16. Dental Pulp Defence and Repair Mechanisms in Dental Caries

    Directory of Open Access Journals (Sweden)

    Jean-Christophe Farges

    2015-01-01

    Full Text Available Dental caries is a chronic infectious disease resulting from the penetration of oral bacteria into the enamel and dentin. Microorganisms subsequently trigger inflammatory responses in the dental pulp. These events can lead to pulp healing if the infection is not too severe following the removal of diseased enamel and dentin tissues and clinical restoration of the tooth. However, chronic inflammation often persists in the pulp despite treatment, inducing permanent loss of normal tissue and reducing innate repair capacities. For complete tooth healing the formation of a reactionary/reparative dentin barrier to distance and protect the pulp from infectious agents and restorative materials is required. Clinical and in vitro experimental data clearly indicate that dentin barrier formation only occurs when pulp inflammation and infection are minimised, thus enabling reestablishment of tissue homeostasis and health. Therefore, promoting the resolution of pulp inflammation may provide a valuable therapeutic opportunity to ensure the sustainability of dental treatments. This paper focusses on key cellular and molecular mechanisms involved in pulp responses to bacteria and in the pulpal transition between caries-induced inflammation and dentinogenic-based repair. We report, using selected examples, different strategies potentially used by odontoblasts and specialized immune cells to combat dentin-invading bacteria in vivo.

    Objects: A neural network was developed to diagnose artificial dental caries using images from a charged-coupled device (CCD)camera and intra-oral digital radiography. The diagnostic performance of this neural network was evaluated against a gold standard. Materials and methods: The neural network design was the Learning Vector Quantization (LVQ) used to classify a tooth surface as sound or as having dental caries. The depth of the dental caries was indicated on a graphic user interface (GUI) screen developed by Matlab programming. Forty-nine images of both sound and simulated dental caries, derived from a CCD camera and by digital radiography, were used to 'train' an artificial neural network. After the 'training' process, a separate test-set comprising 322 unseen images was evaluated. Tooth sections and microscopic examinations were used to confirm the actual dental caries status.The performance of neural network was evaluated using diagnostic test. Results: The sensitivity (95%CI)/specificity (95%CI) of dental caries detection by the CCD camera and digital radiography were 0.77(0.68-0.85)/0.85(0.75-0.92) and 0.81(0.72-0.88)/0.93(0.84-0.97), respectively. The accuracy of caries depth-detection by the CCD camera and digital radiography was 58 and 40%, respectively. Conclusions: The model neural network used in this study could be a prototype for caries detection but should be improved for classifying caries depth. Our study suggests an artificial neural network can be trained to make the correct interpretations of dental caries. (orig.)

    healthy dietary habits are considered to improve oral health and tooth quality. Caries treatment comprises tooth restoration with dental composites and sealants, almost all (> 90%) of which contain bisphenol A (BPA). Study hypotheses were: a) breakfast and oral hygiene habits are important factors in dental caries development; and b) dental caries treatment with epoxy-resins entails a risk of oral exposure to monomers migrating from the polymeric material. We evaluated caries in the teeth of a Spanish school population and determined the percentage treated with dental composites. to relate consumption of breakfast components and oral hygiene habits to dental caries and determine the presence of sealants/composites as potential sources of BPA exposure. subjects: 582 schoolchildren from Granada city (Southern Spain) aged 7 yrs; mean (SD) of 7.55 (0.64) yrs. caries was detected in 21.7% of their teeth. Mean breakfast quality index (BQI) score, based on nutritional questionnaires, was 5.18 (1.29). Breakfast with foods rich in simple sugars representing > 5% of total daily energy was consumed by 24% of the population and was significantly associated with caries frequency in binary logistic regression analysis. Biscuit consumption was reported by 35.8% and significantly associated with caries frequency. Breakfast intake of bakery products/ cereals and of dairy products showed a significant inverse association with caries frequency. No significant relationship was observed between caries and BQI score or oral hygiene factors. further research is required to elucidate the role of diet in caries and the associated risk of exposure to estrogenic xenobiotics such as BPA.

    This study was conducted to assess caries treatment thresholds among Japanese dentists and to identify characteristics associated with their decision to intervene surgically in proximal caries lesions within the enamel. Participants (n = 189) were shown radiographic images depicting interproximal caries and asked to indicate the lesion depth at which they would surgically intervene in both high- and low-caries-risk scenarios. Differences in treatment thresholds were then assessed via chi-square tests, and associations between the decision to intervene and dentist, practice, and patient characteristics were analyzed via logistic regression. The proportion of dentists who indicated surgical intervention into enamel was significantly higher in the high-caries-risk scenario (73.8%, N = 138) than in the low-caries-risk scenario (46.5%, N = 87) (p caries-risk scenario, gender of dentist, city population, type of practice, conducting caries-risk assessment, and administering diet counseling were significant factors associated with surgical enamel intervention. However, for a low-caries-risk scenario, city population, type of practice, and use of a dental explorer were the factors significantly associated with surgical enamel intervention. These findings demonstrate that restorative treatment thresholds for interproximal primary caries differ by caries risk. Most participants would restore lesions within the enamel for high-caries-risk individuals.

Professional clinical management of caries has been very successful in cases of different severities of disease manifestations. However, tertiary management of this disease has been gaining attention, with numerous methods and agents emerging on a daily basis. Higher intake of nutritive sweeteners can result in higher energy intake and lower diet quality and thereby predispose an individual to conditions like obesity, cardiovascular disorders, and type 2 diabetes mellitus. Non-nutritive sweeteners have gained popularity as they are sweeter and are required in substantially lesser quantities. Xylitol, a five-carbon sugar polyol, has been found to be promising in reducing dental caries disease and also reversing the process of early caries.

    2013-11-01

    To provide a brief commentary review of strategies to control dental caries. Dental decay is one of man's most prevalent diseases. In many counties, severity increased in parallel with importation of sugar, reaching its zenith about 1950s and 1960s. Since then, severity has declined in many countries, due to the wide use of fluoride especially in toothpaste, but dental caries remains a disease of medical, social and economic importance. Within the EU in 2011, the cost of dental treatment was estimated to be €79 billion. The pathogenesis is well understood: bacteria in dental plaque (biofilm) metabolise dietary sugars to acids which then dissolve dental enamel and dentine. Possible approaches to control caries development, therefore, involve: removal of plaque, reducing the acidogenic potential of plaque, reduction in sugar consumption, increasing the tooth's resistance to acid attack, and coating the tooth surface to form a barrier between plaque and enamel. At the present time, only three approaches are of practical importance: sugar control, fluoride, and fissure sealing. The evidence that dietary sugars are the main cause of dental caries is extensive, and comes from six types of study. Without sugar, caries would be negligible. Fluoride acts in several ways to aid caries prevention. Ways of delivering fluoride can be classed as: 'automatic', 'home care' and 'professional care': the most important of these are discussed in detail in four articles in this issue of the Acta Medica Academica.

    Dental caries is a major disease that threaten human's oral healthy severely with the characteristics of high incidence, low rate of treatment and high rate of retreatment. At present, restorative treatment remains the main method for caries treatment. With the development of the Minimally Invasive Cosmetic Dentistry (MICD), reasonable application of various treatment technologies, maximum preservation of tooth tissues and realizing the maximization of treatment effects become problems that call for immediate solution in dental clinics. In addition, there still exist a large number of old restorations that need standard retreatments. Here, some difficulty influence factors of dental caries clinical treatment such as systemic and oral factors, individual caries susceptibility, treatment technologies and materials, retreatment methods of old restorations and technique sensitivity are analyzed, and corresponding processing strategies are also put forward.

    We analyzed fluid intake data among children aged 2-10 years from a 24-hour dietary recall interview in the NHANES III (1988-94) to investigate the effect of high consumption of carbonated soft drinks on caries in the primary dentition. We used cluster analysis to determine fluid consumption patterns. Four distinct fluid consumption patterns were identified: high carbonated soft drinks, high juice, high milk, and high water. About 13% of children had a high carbonated soft drink consumption pattern; they also had a significantly higher dental caries experience in the primary dentition than did children with other fluid consumption patterns. A fluid intake pattern comprised mainly of milk, water, or juice was less likely to be associated with dental caries. Findings of this study suggest that high consumption of carbonated soft drinks by young children is a risk indicator for dental caries in the primary dentition and should be discouraged.

  12. Dental caries: an updated medical model of risk assessment.

    Dental caries is a transmissible, complex biofilm disease that creates prolonged periods of low pH in the mouth, resulting in a net mineral loss from the teeth. Historically, the disease model for dental caries consisted of mutans streptococci and Lactobacillus species, and the dental profession focused on restoring the lesions/damage from the disease by using a surgical model. The current recommendation is to implement a risk-assessment-based medical model called CAMBRA (caries management by risk assessment) to diagnose and treat dental caries. Unfortunately, many of the suggestions of CAMBRA have been overly complicated and confusing for clinicians. The risk of caries, however, is usually related to just a few common factors, and these factors result in common patterns of disease. This article examines the biofilm model of dental caries, identifies the common disease patterns, and discusses their targeted therapeutic strategies to make CAMBRA more easily adaptable for the privately practicing professional.

    Full Text Available Statement of Problem: Bitewing radiograph is the main reference for diagnosis of proximal and recurrent caries. There is no software for gathering and analyzing radiologists’ opinion in the field of caries detection on digital bitewing radiograph (DBR. Objectives: The main aim of this study is to introduce the first windows application that could be used for marking caries on DBR. This software is called Dental Caries Marking Software (DCMS. The second aim is to create the first DBR caries dataset to be used for future software development projects in the field of automatic caries detection; also gathering and documenting the disagreements and critiques regarding DCMS. Materials and Methods: DCMS has been designed and implemented by the researchers of this study. This software is divided into two parts. The first part is DCMS writer that is used for gathering the user’s opinion and The second part is DCMS analyzer that is used for reading and analyzing the user’s opinion file. Eight radiologists with different experiences used DCMS for marking dental caries on 200 DBR, 50 of which were repeated twice for assessing the accuracy of each radiologist. Results: A total of 3833 points were marked by 8 users on 150 non repetitive DBR. Only 35 points were marked similarly by 8 users; in other words, 8 users totally agreed with 4% of the caries points. According to 50 repetitive DBR, the maximum accuracy of users was 69% and the minimum was 50%. Conclusions: There is significant debate over the diagnosis of caries on DBR; therefore, for unifying the radiologist’s opinions, the need for intelligent caries detection software is apparent. DCMS is useful software for gathering caries data. Moreover, the use of conventional display monitor has negative impacts on accurate diagnosis of caries on DBR.

    Experiments show that dental caries rates are higher among lead-exposed animals, but this association has not been established in humans. To examine the relationship between blood lead levels and dental caries. Cross-sectional survey conducted from 1988 to 1994 that included a dental examination and venipuncture blood lead assay. A total of 24901 persons aged 2 years and older who participated in the Third National Health and Nutrition Examination Survey, which assessed the health and nutritional status of children and adults in the United States. For children aged 2 to 11 years, the sum of decayed and filled deciduous or primary surfaces; for persons aged 6 years and older, the sum of decayed and filled permanent surfaces; for those 12 years and older, the sum of decayed, missing, and filled surfaces. The log of blood lead level was significantly associated with the number of affected surfaces for both deciduous and permanent teeth in all age groups, even after adjusting for sociodemographic characteristics, diet, and dental care. Among children aged 5 to 17 years, a 0.24-micromol/L (5-microg/dL) change in blood lead level was associated with an elevated risk of dental caries (odds ratio, 1.8; 95% confidence interval, 1.3-2.5). Differences in blood lead level explained some of the differences in caries prevalence in different income levels and regions of the United States. We estimated the population attributable risk of lead exposure to be 13.5% and 9.6% of dental caries occurring in 5- to 17-year-olds exposed to the high and moderate levels, respectively. Environmental lead exposure is associated with an increased prevalence of dental caries in the US population. Findings may help explain the distribution of caries by income and region of the United States.

    To (1) identify the methods that dentists in The Dental Practice-Based Research Network (DPBRN) use to diagnose dental caries; (2) quantify their frequency of use and (3) test the hypothesis that certain dentist and dental practice characteristics are significantly associated with their use. A questionnaire about methods used for caries diagnosis was sent to DPBRN dentists who reported doing some restorative dentistry; 522 dentists participated. Questions included the use of dental radiographs, the dental explorer, laser fluorescence, air-drying and fiber-optic devices and magnification as used when diagnosing primary, secondary/recurrent or non-specific caries lesions. Variations on the frequency of their use were tested using multivariate analysis and Bonferroni tests. Overall, the dental explorer was the instrument most commonly used to detect primary occlusal caries and caries at the margins of existing restorations. In contrast, laser fluorescence was rarely used to help diagnose occlusal primary caries. For proximal caries, radiographs were used to help diagnose 75%–100% of lesions by 96% of the DPBRN dentists. Dentists who use radiographs most often to assess proximal surfaces of posterior teeth were significantly more likely to also report providing a higher percentage of patients with individualized caries prevention (p=.040) and seeing a higher percentage of pediatric patients (p=.001). The use of specific diagnostic methods varied substantially. The dental explorer and radiographs are still the most commonly used diagnostic methods..

    Full Text Available Policy were introduced to control fluoride exposure and to reduce the prevalence of fluorosis. The study aimed of describing the prevalence, severity and risk factors for fluorosis, and to describe the trend of fluorosis among Indian children. The study also aimed of exploring the effect of the change in fluoride exposure on dental fluorosis and caries. Establishing an appropriate use of fluoride toothpaste could be successful in reducing fluorosis without a significant increase in caries experience. The use of fluorides for oral health has always involved a balance between the protective benefit against dental caries and the risk of developing fluorosis. The link between fluoride and dental health was established to determining the causes of dental fluorosis or enamel mottling. Fluorosis in Indian children was highly prevalent in the early 1990s.

    0.43 (0.41/0.45) and the specificity was 0.97 (0.95/0.98) and 0.89 (0.88/0.90).With regard to the dentine lesions the sensitivities were 0.36 (0.24-0.49) for proximal to 0.56 (0.53-0.59) for occlusal lesions and specificities ranged between 0.87 (0.85-0.89) and 0.95 (0.94-0.96). No reports were found for cavitated occlusal lesions. For proximal lesions sensitivities were above 0.60 and sensitivities above 0.90. Diagnostic Odds Ratios (DOR) were >1 (indicates a useful test) and were higher in proximal than in occlusal lesions. The DOR calculated for proximal lesions in vitro studies was 16.0 (11.5/22.4) and DOR 7.5 (3.4/16.5) for clinical studies). Heterogeneity calculated using I(2) test was moderate: > 50-67%.ConclusionsCaries detection determined by dental radiographs is highly accurate for proximal lesions and dentine caries lesions. For initial carious lesions the test needs to be used with other more sensitive methods in populations that present with high caries risk.

    BACKGROUND. The change towards a more Westernised diet in Libya may increase the risk of caries and erosion in children. AIMS. To investigate any association between dental caries, dental erosion, and potential dietary risk factors in Libyan schoolchildren. METHODS. A random sample of 791 schoolchildren aged 12 years underwent dental examination for caries and erosion and completed a questionnaire to provide dietary data. Dental caries was assessed using the WHO (Oral Health Surveys: Basic Methods, 1997) criteria. Erosion was assessed using UK National Diet and Nutrition Survey (NDNS, Young People Aged 4-18 years. Volume 2: Report of the Oral Health Survey, 2000) criteria. Associations between caries and dietary variables were investigated through bivariate and multivariate analyses. RESULTS. Of the 791 12-year olds, 57.8% (457) had caries experience and 40.8% (323) had experience of erosion. One hundred and ninety-two subjects (42%) of the subjects with caries experience also had erosion, whilst 131 subjects (39.2%) of the 334 without caries had clinical signs of erosion (P = 0.464; OR, 1.123; 95% CI, 0.842, 1.497). There was no statistically significantly relationship between dental caries and dental erosion. Frequency of consumption of fruit-based sugared drinks was statistically significantly positively associated with experience of caries (P = 0.002). CONCLUSIONS. Dental caries experience was associated with frequency of consumption of sugared dietary items but not with dental erosion. © 2011 The Authors.

    2014-01-01

    Background To investigate the role of geography (place of residence) as a moderator in the relationship between dental caries disease and treatment experience and dental fear in 16-year-olds living in Malaysia. Methods A multi-stage-stratified sampling method was employed. Five hundred and three, 16-year-olds from 6 government secondary schools participated in this study. The questionnaire examined participants’ demographic profile and assessed their dental fear using the Dental Fear Survey (DFS). The clinical examination consisted of the DMFT as the outcome measure of dental caries disease and treatment experience by a single examiner (ICC = 0.98). Structural equation modelling inspected the relationship between dental fear and dental caries disease and treatment experience. Results The mean DMFT was 2.76 (SD 3.25). The DT, MT and FT components were 0.64 (SD 1.25), 0.14 (SD 0.56) and 1.98 (SD 2.43) respectively. Rural compared with urban adolescents had significantly greater mean numbers of decayed and missing teeth. The mean DFS score was 40.8 (SD 12.4). Rural compared with urban adolescents had significantly higher mean scores for physical symptoms of dental fear. The correlation between dental fear (DFS) and dental caries disease and treatment experience (DMFT) was 0.29, p dental caries disease and treatment experience. The strength of the relationship between dental fear and dental caries disease and treatment experience varied in accordance with place of residence. Conclusion In conclusion a relationship between dental fear and dental caries disease and treatment experience was shown to exist in 16-year-old adolescents living in Malaysia. This study showed that the rural–urban dichotomy acted as a moderator upon this relationship. PMID:24621226

    Full Text Available The purpose of this study was to identify risk indicators of high caries level at baseline (HCLB based on cross-sectional data and predictors of high caries increment (HCI based on a 7-year-follow-up examination in 6-8-year-old schoolchildren. Two hundred and six schoolchildren were examined in 1997 and in 2004 by the same two calibrated dentists, in Piracicaba, Brazil. At baseline, dental caries, presence of sealants, fluorosis, and oral hygiene status were recorded. The children's parents completed a questionnaire concerning socioeconomic level, fluoride use, dental service utilization, dietary and oral hygiene habits. HCLB and HCI were defined considering the upper quartile of the total caries experience distribution (dmfs+DMFS and caries increment distribution, respectively. Logistic regression models were adjusted estimating the Odds Ratio (OR, 95% confidence intervals and p-values. Having white spot lesions (OR=5.25 was found to be a risk indicator of HCLB. Schoolchildren with dental fluorosis (OR=0.17 or those who brushed the teeth more than two times a day (OR=0.37 presented less probability of HCLB. The predictors of HCI were: dmfs>0 (OR=2.68 and mothers' educational level up to 8 years of schooling (OR=2.87. Clinical and socioeconomic variables were found to be risk indicators and/or predictors of dental caries in schoolchildren.

    (1) To describe caries lesions development and the role of fluoride in controlling disease progression; (2) to evaluate whether the use of fluoride-releasing pit and fissure sealants, bonding orthodontic agents and restorative materials, in comparison to a non-fluoride releasing material, reduces caries incidence in children or adults, and (3) to discuss how the anti-caries properties of these materials have been evaluated in vitro and in situ. The search was performed on the Cochrane Database of Systematic Reviews and on Medline via Pubmed. Caries is a biofilm-sugar dependent disease and as such it provokes progressive destruction of mineral structure of any dental surface - intact, sealed or restored - where biofilm remains accumulated and is regularly exposed to sugar. The mechanism of action of fluoride released from dental materials on caries is similar to that of fluoride found in dentifrices or other vehicles of fluoride delivery. Fluoride-releasing materials are unable to interfere with the formation of biofilm on dental surfaces adjacent to them or to inhibit acid production by dental biofilms. However, the fluoride released slows down the progression of caries lesions in tooth surfaces adjacent to dental materials. This effect has been clearly shown by in vitro and in situ studies but not in randomized clinical trials. The anti-caries effect of fluoride releasing materials is still not based on clinical evidence, and, in addition, it can be overwhelmed by fluoride delivered from dentifrices.

  7. The implications of the new paradigm of dental caries.

    The caries process is the ubiquitous, natural metabolism in the biofilm that causes numerous fluctuations in pH. The interaction of this biofilm with the dental tissues may result in a caries lesion. However, lesion formation and progression can be controlled, particularly by disturbing plaque regularly with a fluoride containing toothpaste. This paradigm implies that everyone with teeth is at risk to lesion development. Treatment of caries is principally non-operative, involving plaque control, fluoride and a sensible diet. Operative dentistry repairs un-cleansable cavities and is part of plaque control. A diagnosis is a mental resting place on the way to a treatment decision. The relevant diagnostic features with respect to caries are lesion activity (active lesions require active management) and un-cleansable cavities. When teaching undergraduates, it is important that they are credited for the non-operative treatment of caries as well as for operative dentistry. This is equally important in dental practice where an appropriate skills mix of the dental team is required to deliver dental health cost-effectively. Training more dentists may be an expensive mistake as far as disease control is concerned. It is ironic that dentists make most money from operative care and specialist treatment when disease control could be delivered relatively cheaply. The key to dental health is regular and effective plaque control with a fluoride containing toothpaste, from cradle to grave. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Dental caries is one of the most common chronic childhood diseases affecting a large portion of children in the United States. The prevalence of childhood dental caries in Kentucky is among the highest in the nation. The purposes of this study are to (1) compare sociodemographic differences between caries and no caries groups and (2) investigate factors associated with untreated dental caries among children who visited a mobile dental clinic in South Central Kentucky. Study subjects were children aged 6 to 15 years who participated in the school-based dental sealant program through the mobile dental clinic operated by the Institute for Rural Health at Western Kentucky University between September 2006 and May 2011 (n = 2,453). Descriptive statistics were calculated for sociodemographic factors (age, gender, race/ethnicity, insurance status, and urban versus rural residential location) and caries status. We used chi-square tests to compare sociodemographic differences of children stratified by caries and no caries status as well as three levels of caries severity. We developed a logistic regression model to investigate factors associated with untreated dental caries while controlling for sociodemographic characteristics. The proportion of children having untreated dental caries was 49.7% and the mean number of untreated dental caries was 2.0. The proportion of untreated dental caries was higher in older children, children with no insurance and living in rural residential locations, and caries severity was also higher in these groups. Odds ratio indicated that older ages, not having private insurance (having only public, government-sponsored insurance or no insurance at all) and rural residential location were associated with having untreated dental caries after controlling for sociodemographic characteristics of children. Untreated dental caries was more likely to be present in older children living in rural areas without insurance. Health interventionists may use

    2016-03-01

    We report the development of a polarization-resolved hyperspectral stimulated Raman scattering (SRS) imaging technique based on a picosecond (ps) laser-pumped optical parametric oscillator system for label-free imaging of dental caries. In our imaging system, hyperspectral SRS images (512×512 pixels) in both fingerprint region (800-1800 cm-1) and high-wavenumber region (2800-3600 cm-1) are acquired in minutes by scanning the wavelength of OPO output, which is a thousand times faster than conventional confocal micro Raman imaging. SRS spectra variations from normal enamel to caries obtained from the hyperspectral SRS images show the loss of phosphate and carbonate in the carious region. While polarization-resolved SRS images at 959 cm-1 demonstrate that the caries has higher depolarization ratio. Our results demonstrate that the polarization resolved-hyperspectral SRS imaging technique developed allows for rapid identification of the biochemical and structural changes of dental caries.

    The authors conducted a study to validate the following 3 evidence-based, process-of-care quality measures focused on dental caries prevention for children with an elevated risk of experiencing caries: sealants for 6- to 9-year-olds, sealants for 10- to 14-year-olds, and topical fluoride. Using evidence-based guidelines, the Dental Quality Alliance developed measures for implementation with administrative data at the plan and program levels. To validate the measures, the authors used data from the Florida and Texas Medicaid programs and Children's Health Insurance Programs and from national commercial dental benefit plans. Data were extracted from 414 randomly selected dental office records to validate the use of administrative data to accurately calculate the measures. The authors also assessed statistically significant variations in overall measure performance. Agreement between administrative data and dental records was 95% for sealants (κ = 0.82) and 90% for topical fluoride (κ = 0.78). Sensitivity and specificity were 90.7% and 88.5% for topical fluoride and 77.8% and 98.8% for sealants, respectively. Variation in overall measure performance was greatest for topical fluoride (χ(2) = 5,887.1; P caries received at least 2 topical fluoride applications during the reporting year. Although there was greater variation in performance for sealants for 6- to 9-year-olds (range, 21.0-31.3%; χ(2) = 548.6; P caries prevention process-of-care quality measures can be implemented feasibly and validly using administrative claims data. The measures can be used to assess, monitor, and improve the proportion of children with an elevated risk of experiencing dental caries who receive evidence-based caries prevention services.

    Although animal experiments have shown that cadmium exposure results in severe dental caries, limited epidemiologic data are available on this issue. We aimed to examine the relationship between environmental cadmium exposure and dental caries in children 6-12 years of age. We analyzed cross-sectional data, including urine cadmium concentrations and counts of decayed or filled tooth surfaces, from the Third National Health and Nutrition Examination Survey. We used logistic and zero-inflated negative binomial (ZINB) regression to estimate the association between urine cadmium concentrations and caries experience, adjusting these analyses for potential confounders including environmental tobacco smoke (ETS). Urine cadmium concentrations ranged from 0.01 to 3.38 ng/mL. Approximately 56% of children had experienced caries in their deciduous teeth, and almost 30% had been affected by caries in their permanent dentition. An interquartile range (IQR) increase in creatinine-corrected cadmium concentrations (0.21 microg/g creatinine) corresponded to a 16% increase in the odds of having experienced caries in deciduous teeth [prevalence odds ratio (OR)=1.16; 95% confidence interval (CI), 0.96-1.40]. This association was statistically significant in children with low ETS exposure (prevalence OR=1.30; 95% CI, 1.01-1.67). The results from the ZINB regression indicated that, among children with any caries history in their deciduous teeth, an IQR increase in cadmium was associated with 17% increase in the number of decayed or filled surfaces. We observed no association between cadmium and caries experience in permanent teeth. Environmental cadmium exposure may be associated with increased risk of dental caries in deciduous teeth of children.

    We explored the epidemiological risk factors for dental caries to help explain differences in the prevalence of adult dental caries. We examined 841 people for the presence of Helicobacter pylori in their dental plaque and for dental caries. Of the 841 subjects, 574 (68.25%) were infected with H pylori, and 516 (61.36%) were diagnosed with dental caries. Among the 574 subjects with H pylori, the prevalence of dental caries was 73.52% (422/574), while the prevalence among the 267 cases without H pylori was 35.21% (94/267). A correlation existed between the presence of H pylori and the occurrence of dental caries (χ(2) = 112.8, P oral cavity is associated with dental caries and poor dental hygiene.

    Caries is defect of the hard dental tissue which is cause by cariogenic microorganisms in the oral cavity. New classification of caries is D1, D2, D3 and D4. D1 is caries in the first layer of enamel. D2 is caries in the second layer of enamel till the margin of dentine ( caries superficial ). D3 is caries in the first layer of dentine ( caries media ).D4 is caries on the top of pulp chamber ( caries pulpae proxima ). One of the most frequently used methods of radiography to detect of caries is bitewing ( BTW ) radiography. (authors)

    Full Text Available BACKGROUND Dental caries is a universal health problem with involving the people globally of all regions and society. The agonising fact is that despite several efforts towards total eradication, dental caries is still prevalent. As the prevalence of dental caries is very high among school children and there is a paucity of such data in Coimbatore and the literature review does not reveal many such studies from this area, the study was conducted in the school going children in Sulur. MATERIALS AND METHODS All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. A health screening camp was conducted for the students in private school, Sulur, February 20-25, 2017, by a team of doctors from PSG UHTC. A total of 1945 students were screened. The students health details have been entered in their health card and those requiring further evaluation have been counseled and the nursing staff at school has been requested to facilitate and guide for followup. All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. All the students who were present in school during 20th to 25th were screened and considered as the inclusion criteria. The exclusion criteria were the absentees during this period. The students were made to sit in an ordinary chair in broad daylight facing away from the sunlight and examined in their school. Data were compiled in an excel worksheet and the percentage calculated. RESULTS A total of 1945 students were screened, of which, 541 students were found to have dental problems that is about 28% of the total screening done. The percentage of dental caries were found to be higher compared to other dental diseases like deep caries, malalignment, malocclusion and calculus. The percentage of dental caries was found to be higher in the females about 78% than the male for whom it was about 72%. The percentage of deep

    This study was conducted to determine prevalence and severity of dental fluorosis and dental caries in school-children living in two zones of the Mexico City's East Area. Fluorosis and caries scores were recorded for 1,569 children according to the Dean Community Index, DMFT and DMFS indexes, and the relationship between fluorosis and fluoride sources was investigated. Dental fluorosis was found in 60.42% of children. Dean's Community score was 0.96 (SD-0.58). Quantity of toothpaste employed, toothbrushing frequency, and early initiation of toothbrushing correlated well with fluorosis (p = 0.03). Caries was present in 70.52% of children, DMFT and DMFS scores were 2.64 (SD 2.4) and 3.97 (SD 4.18) respectively. DMFT and DMFS scores were lower in children with mild and moderate fluorosis than in those fluorosis-free children. (p = 0.03).

    Full Text Available Objective: Tooth decay continues to come up as a serious health problem particularly in developing countries. Limited number of studies investigated the prevalence of complication of untreated dental caries as abscess, fistula and ulceration. The purpose of the present study was to investigate the prevalence of the clinical consequences of untreated dental caries among a group of children. Materials and Method: The study was conducted on 1200 children with ages between 5-12 years in the Department of Pedodontics, Faculty of Dentistry, GaziUniversity between the dates 1-31 March 2012. Caries in deciduous and permanent teeth were scored using DMFT/dmft and PUFA/pufa indexes (D/d: decayed, M/m: missing, F/f: filled, P/p: carious lesion with pulpal involvement, U/u: ulceration of the mucosa due to root fragments, F/f: fistula, A/a: abscess. Results: DMFT index was 2.34 ± 1.37 and dmft index was 4.25 ± 3.46. The prevalence of PUFA/pufa for permanent and deciduous teeth was 2.30% and 22.25%, respectively. The highest score in both permanent and deciduous teeth was caries lesions with pulpal involvement (%11.24 for deciduous teeth and %1.67 for permanent teeth. This was followed by abscess and fistula formation. Conclusion: The prevalence of clinical consequences of untreated dental caries was high for deciduous teeth in the selected population. The PUFA/pufa index is seen as an epidemiological tool complementary to the existing caries index aimed to assess dental caries.

    To estimate the prevalence and severity of dental caries and the dental treatment necessities of school children in Mexico City. The studied population was surveyed for dental caries in 1988 to obtain data necessary for the National Program of Salt Fluoridation in Mexico. The population was selected with a sample frame based on a list of Kindergartens and primary schools registered at the Ministry of Public Education in 1988. The oral cavity examination was based on diagnostic criteria marked by the World Health Organization. A total of 4475 scholars of 5 to 12 years of age were included in the study. Dental caries prevalence in the population reached 90.5%. The index of treatment necessities was high (79.6%). The mean of caries index in scholars of 12 years of age was DMFT = 4.42 (SD = 3.2) and DMFS = 6.53 (SD = 4.8). Results emphasize the pertinence of a widely reaching preventive program of such as salt fluoridation. Additionally, strategies to improve access of the school children population to dental services must be elaborated.

    Cavitation in teeth results from a pathogenic process termed dental caries that has occurred on the tooth surface for weeks or even years. Accumulation of dental plaque (biofilm) on the tooth is usually the first manifestation of the disease. Although acid production is the immediate and proximal cause of dissolution of teeth; it is the milieu within which the acid is formed that should be of primary concern. Focusing on the 'critical pH' has detracted attention from the more biological aspects (biofilm formation) of dental caries. Dental caries is unique; it is a biological process occurring on essentially an inert surface. Investigation of the multitude of interactions occurring in plaque ranging from enamel interfaces to surfaces of bacteria and matrices poses challenges worthy of the best scientific minds. The mouth clearly offers unique opportunities to investigate the multi facets of biofilm formation in vivo, generating data that have relevance way beyond the mouth. Prevention of this ubiquitous disease, dental caries, continues to present serious challenges. The public health benefits of fluoride delivered in its various formats are well recognized. Nevertheless, additional preventive approaches are required. Overcoming the rapid clearance of agents from the mouth is particularly challenging. Building on the polymerizing capacity of glucosyltransferases it may be possible to incorporate a therapeutic agent into the matrix plaque, thereby delivering therapeutic agents precisely to where they are needed. © 2015 John Wiley & Sons A/S.

    2012-03-01

    To assess dental fluorosis, dental caries and quality of life factors associated with dental fluorosis among schoolchildren living in a Colombian endemic dental fluorosis area. 110 12-year olds were visually examined for dental caries (ICDAS) and dental fluorosis (TF) and a self-administered quality of life and fluorosis questionnaire was applied. The prevalence of dental fluorosis reached 100% in this sample with most children falling within the TF 3 severity category. Varying degrees of severity were observed as follows for TF 1 to 6: 1%, 16%, 62%, 16%, 4%, 2%. The prevalence of caries experience (DF-S2) was 54%. The DF-S2 mean was 4.4 (sd 4.3). The principal contributor to the DF-S2 outcome was the decayed component. When initial caries lesions were included (ICDAS-scores 1-3) the mean DF-S1,2 increased to 10 (sd 5.1). The association between fluorosis and dental caries was not statistically significant (p > 0.05). Children not only detected the presence of something abnormal in their teeth but also reported feeling embarrassed, and worried due to their dental appearance. Almost 60% of the children reported avoiding smiling because of their teeth's appearance. The high prevalence of dental fluorosis and dental caries combined with the schoolchildren's negative perception about their dental health reflects the need to propose effective dental public health policies to regulate multiple exposures to fluoride at an early age, and to improve health outcomes in a highly vulnerable population.

    Full Text Available Abstract Introduction: The rate of tooth decay and periodontal diseases today is still high, regardless of progress in oral and dental hygiene. The traditional toothbrush or chewing stick called "Miswak" has been used since ancient times. Many significant effects of Miswak such as antibacterial, anti-caries and antiperiopathic effects have been recognized today. Tooth care is a very important issue and both prevention and treatment of dental caries could be very helpful in maintaining good personal health. In this research, the efficacy of natural toothbrush or Miswak in prevention of dental caries was investigated and compared with the efficacy of ordinary toothbrush and toothpaste. Aim: Miswak was introduced for preventing dental caries by the Holy Prophet Mohammad (S.A.W 1400 years ago and has been used since then in many Islamic countries. In this research, the efficacy of Miswak in prevention of dental caries was investigated and compared with the efficacy of ordinary toothbrush. Methods: This analytical and clinical trial was performed in a high school student population (girls and boys in the city of Yazd, Iran in 2001-2002. Twelve high schools were randomly chosen. From these high schools, 380 second year students (190 cases and 190 controls were enrolled and their teeth condition such as the number of decayed, missing and filled teeth (DMF were recorded in a specific questionnaire. The degrees of decay in the decayed teeth were recorded as well. Then, Miswak sticks were distributed to the case group and required dental training was given to both groups. After one year, the examinations were repeated and findings recorded in the same questionnaires. For analyzing the data, one-way variance analysis, Chi square, Paired t-test and two variable analyses were used. Results: At the start of the study, there were no significant differences between the two groups (case and control with regards to their dental condition and the frequency of

    Science.gov (United States)

    To provide health care providers, patients, and the general public with a responsible assessment of currently available data regarding the diagnosis and management of dental caries throughout life. A non-Federal, non-advocate, 13-member panel representing the fields of dentistry, epidemiology, genetics, medicine, oral biology, oral radiology, pathology, periodontics, public health, statistics, surgery, and including a public representative. In addition, 31 experts in these same fields presented data to the panel and to a conference audience of approximately 700. Presentations by experts; a systematic review of the dental research literature provided by the Agency for Healthcare Research and Quality; and an extensive bibliography of dental caries research papers, prepared by the National Library of Medicine. Scientific evidence was given precedence over clinical anecdotal experience. Answering predefined questions, the panel drafted a statement based on the scientific evidence presented in open forum and the scientific literature. The draft statement was read in its entirety on the final day of the conference and circulated to the experts and the audience for comment. The panel then met in executive session to consider these comments and released a revised statement at the end of the conference. The statement was made available on the World Wide Web at http://consensus.nih.gov immediately after the conference. This statement is an independent report of the panel and is not a policy statement of the NIH or the Federal Government. This Consensus Development Conference, the first sponsored by the NIH on dental caries, provided an excellent venue to describe the great success that has been achieved in reducing caries prevalence. More importantly, it provided a public forum to review both the strengths and weaknesses of current dental caries research and clinical procedures. Effective preventive practices, such as the use of fluoride, sugarless products, and dental

    In their maxillofacial practice, the authors have encountered some children with severe dental caries whose teeth had to be removed; many later appeared to be abused children. The authors hypothesized that in the group of children who underwent multiple tooth extractions for caries under general anesthesia, a larger percentage would be found to be abused compared with the normal population. The authors identified children who underwent multiple tooth extractions under general anesthesia in a well-defined region in the Netherlands in 2005 and 2006. Subsequently, they sought these children in the database of the Dutch national organization against domestic violence and child abuse (Veilig Thuis) in 2015. Of the total group of 376 children, 205 (55%) underwent the procedure because of caries during this period. Child abuse and neglect was established by Veilig Thuis in 47 of these children (23%; 95% confidence interval, 20-26), whereas the procedure occurred before the child abuse was established in 27. There appears to be a strong association between severe dental caries and child abuse and neglect. Hence, severe dental caries could be regarded as an early symptom of child abuse and neglect.

    Full Text Available Background: Dental caries is a multifactorial disease, and its etiology has been advocated to various environmental and genetic factors. Dermatoglyphics is the study of dermal ridges on the palmar and plantar surfaces of hands and feet. It is genetic in nature and is unique to each individual. Enamel as well as finger buds are ectodermal in origin and develop during the same time of intrauterine life; therefore, factors affecting dental caries may cause peculiarities in dermal ridge patterns. Aim: To find a correlation between dermatoglyphic pattern and dental caries in pediatric cases. Materials and Methods: A cross-sectional study was performed on 200 children (100 caries-active and 100 caries-free between the age range of 6–13 years. The decayed, missing, and filled teeth (DMFT score was recorded for caries-active children having a score range of 3–6 and under each score there were 25 cases. Midlo and Cummins method (1943 of recording palm prints was used using Indiana Ink (stamp pad, roller and printing papers. The prints were inspected with the help of magnifying lens and whorls and loops in each hand were recorded. Statistical Analysis: Statistical analysis was performed using SPSS software 14.00, and Chi-square test was used for statistical analysis of collected data. Results: The number of whorls was found to be more in caries-active children with increased number of whorls in children with a higher DMFT whereas the number of loops was more in caries-free children. There was a statistically significant difference between the groups (P < 0.05. The number of whorls and loops was found to be more on the right hand as compared to the left hand. Conclusion: The results of the study indicate that there is a definite correlation between the number of whorls and loops and the presence of dental caries in children. Hence, dermatoglyphics can be used as a screening method to provide adequate preventive treatment to children showing a higher

    Full Text Available Abstract The aim of this study was to assess the clinical and socioeconomic indicators associated with dental anxiety in preschool children with severe dental caries. A total of 100 children between 3 and 5 years of age were selected during a dental screening procedure. The selection criteria were having at least one tooth with dental caries and a visible pulpal involvement, ulceration, fistula, and abscess (PUFA index of ≥1 in primary teeth. Before the clinical examination or any treatment procedure was performed, we evaluated the children’s dental anxiety using the Facial Image Scale (FIS. Parents completed a questionnaire on socioeconomic conditions, which included the family structure, number of siblings, parental level of education, and family income. A dentist blinded to FIS and socioeconomic data performed the clinical examination. Poisson regressions associate clinical and socioeconomic conditions with the outcome. Most of the children (53% experienced extensive dental caries (dmf-t ≥ 6, and all children had severe caries lesions, with a PUFA index of ≥1 in 41% and that of ≥2 in 59%. The multivariate adjusted model showed that older children (4–5-year old experienced lower dental anxiety levels compared with younger children (3-year old (RR = 0.35; 95%CI: 0.17–0.72 and RR = 0.18; 95%CI: 0.04–0.76, respectively, and children with three or more siblings were associated with higher levels of dental anxiety (RR = 2.27; 95%CI: 1.06–4.87. Older age is associated with low dental anxiety, and more number of siblings is associated with high dental anxiety in preschool children, whereas the severity or extent of dental caries is not associated with dental anxiety.

The selection criteria were having at least one tooth with dental caries and a visible pulpal involvement, ulceration, fistula, and abscess (PUFA) index of ≥1 in primary teeth. Before the clinical examination or any treatment procedure was performed, we evaluated the children's dental anxiety using the Facial Image Scale (FIS). Parents completed a questionnaire on socioeconomic conditions, which included the family structure, number of siblings, parental level of education, and family income. A dentist blinded to FIS and socioeconomic data performed the clinical examination. Poisson regressions associate clinical and socioeconomic conditions with the outcome. Most of the children (53%) experienced extensive dental caries (dmf-t ≥ 6), and all children had severe caries lesions, with a PUFA index of ≥1 in 41% and that of ≥2 in 59%. The multivariate adjusted model showed that older children (4-5-year old) experienced lower dental anxiety levels compared with younger children (3-year old) (RR = 0.35; 95%CI: 0.17-0.72 and RR = 0.18; 95%CI: 0.04-0.76, respectively), and children with three or more siblings were associated with higher levels of dental anxiety (RR = 2.27; 95%CI: 1.06-4.87). Older age is associated with low dental anxiety, and more number of siblings is associated with high dental anxiety in preschool children, whereas the severity or extent of dental caries is not associated with dental anxiety.

    The purpose of this study was to assess the prevalence of caries in children aged 8-13 years having dental fluorosis and to determine the correlation between the grades of dental fluorosis and caries. 451 school children in the age group of 8-13 years were selected for the study and were divided into six age groups. The children were assessed for dental fluorosis according to Dean's criteria Index of fluorosis, and dental caries according to WHO basic survey guidelines. The overall oral health status of the child was assessed by DMFT index. The results of the present study revealed that the prevalence of grade 2 fluorosis was the highest and grade 5 fluorosis was the lowest in all the age groups. Number of children having dental fluorosis was highest in the age group between 12-13 years followed by the age group between 13-14 years. The overall DMFT increased as the age of the children increased in the different age groups. The DMFT increased as the severity of fluorosis increased upto grade 2 and then decreased from grade 3 to grade 5.

    The aim of this study was to assess the caries experience of Hungarian police students and to evaluate its relationship with nutrition, oral hygiene habits, behavioural and social factors. This representative cross-sectional epidemiological survey was conducted in a dental office of the Miskolc Law Enforcement Secondary School in Hungary in 2008. Altogether 792 Hungarian police student volunteers (male/female ratio was 90.3/9.7%, age: 20.4 ± 1.3 years, mean ± SD) participated in the study. Caries experience was measured using World Health Organization criteria and a validated questionnaire was used to collect social and oral health behaviour data. The DMFT number was 10.3 ± 5.7 (mean ± SD). Significant relationships were found between the DMFT value and the education of fathers, frequency of dental attendance, and use of dental floss (p dental attendance, while from the components the FT value showed statistically significant relationships with the education of fathers and the MT component with the use of dental floss (p < 0.05). Based on the results of this survey, strategies aiming at effective caries-preventive programmes should be established in police student populations ensuring the official basic requirements on their health condition and suitability for subsequent service. The published information can be used as a base for new strategies, and allows the evaluation of the effects of a carefully planned and implemented health care system. Copyright © 2012 S.

    Dental caries is a disease characterized by demineralization of enamel crystals leading to the penetration of bacteria into the dentine and pulp. Early detection of enamel demineralization resulting in increased enamel porosity, commonly known as white spots, is a difficult diagnostic task. Laser induced autofluorescence was shown to be a useful method for early detection of demineralization. The existing studies involved either a single point spectroscopic measurements or imaging at a single spectral band. In the case of spectroscopic measurements, very little or no spatial information is acquired and the measured autofluorescence signal strongly depends on the position and orientation of the probe. On the other hand, single-band spectral imaging can be substantially affected by local spectral artefacts. Such effects can significantly interfere with automated methods for detection of early caries lesions. In contrast, hyperspectral imaging effectively combines the spatial information of imaging methods with the spectral information of spectroscopic methods providing excellent basis for development of robust and reliable algorithms for automated classification and analysis of hard dental tissues. In this paper, we employ 405 nm laser excitation of natural caries lesions. The fluorescence signal is acquired by a state-of-the-art hyperspectral imaging system consisting of a high-resolution acousto-optic tunable filter (AOTF) and a highly sensitive Scientific CMOS camera in the spectral range from 550 nm to 800 nm. The results are compared to the contrast obtained by near-infrared hyperspectral imaging technique employed in the existing studies on early detection of dental caries.

    Environmental pollution is a significant health hazard and is mainly caused by commercialization. The etiology of dental caries is multifactorial and one such factor is exposure to trace element such as lead. Hence, the present study was carried out to find out the correlation between the levels of lead in the enamel, saliva and dental caries in children. 90 children aged 5 years consisting of both genders from different kindergartens along Coastal Karnataka were included in the study. The selected children were divided into 3 groups as; control group, early childhood caries (ECC) group and severe-ECC (S-ECC) group respectively. Enamel and salivary lead level was assessed by using graphite atomic absorption spectrophotometry. Mean enamel lead levels in the control, ECC and S-ECC group were 47.7, 85.45 and 90.43 ppm respectively and mean salivary lead levels were 0.23, 1.7 and 1.77 ppm respectively which was statistically very highly significant (p lead levels (p > 0.05). The enamel and the saliva of all the children had measurable amounts of lead and its levels increased with increase in severity of dental caries proving the cariogenic potential of lead. A positive correlation was seen between the enamel and the salivary lead levels.

    The problem of identifying potential determinants and predictors of dental caries is of key importance in caries research and it has received considerable attention in the scientific literature. From the methodological side, a broad range of statistical models is currently available to analyze dental caries indices (DMFT, dmfs, etc.). These models have been applied in several studies to investigate the impact of different risk factors on the cumulative severity of dental caries experience. However, in most of the cases (i) these studies focus on a very specific subset of risk factors; and (ii) in the statistical modeling only few candidate models are considered and model selection is at best only marginally addressed. As a result, our understanding of the robustness of the statistical inferences with respect to the choice of the model is very limited; the richness of the set of statistical models available for analysis in only marginally exploited; and inferences could be biased due the omission of potentially important confounding variables in the model's specification. In this paper we argue that these limitations can be overcome considering a general class of candidate models and carefully exploring the model space using standard model selection criteria and measures of global fit and predictive performance of the candidate models. Strengths and limitations of the proposed approach are illustrated with a real data set. In our illustration the model space contains more than 2.6 million models, which require inferences to be adjusted for 'optimism'.

    To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile. A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7). The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development. This pilot study indicates that the severity of dental caries is correlated with early childhood development. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Fluoridated dentifrices reduce dental caries in subjects who perform effective oral hygiene. Actinomyces naeslundii increases in teeth-adherent microbial biofilms (plaques) in these subjects, and a well-characterized serum immunoglobulin G (IgG) antibody response (Actinomyces antibody [A-Ab]) is also increased. Other studies suggest that a serum IgG antibody response to streptococcal d-alanyl poly(glycerophosphate) (S-Ab) may indicate caries experience associated strongly with gingival health and exposure to fluoridated water. The aim of this study was to investigate relationships between A-Ab response, oral hygiene, S-Ab response, and caries experience. Measurements were made of A-Ab and S-Ab concentrations, caries experience (number of decayed, missing, and filled teeth [DMFT], number of teeth surfaces [DMFS], and number of decayed teeth needing treated [DT]), exposure to fluoridated water (Flu), mean clinical pocket depth (PD; in millimeters), and extent of plaque (PL) and gingival bleeding on probing (BOP). A-Ab concentration, the dependent variable in a multiple regression analysis, increased with S-Ab concentration and decreased with PL and DMFT adjusted for Flu (R(2) = 0.51, P caries in subjects performing effective oral hygiene using fluoridated dentifrices. Conversely, a low A-Ab response is suggestive of decreased A. naeslundii binding to saliva-coated apatite and greater caries experience, as reported by others.

    This study aimed to analyze the validity of self-perceived dental caries and associated factors in a sample of 795 adults (35-44 years). The dependent variable was self-perceived dental caries, and the independent variables were combined in blocks. Three logistic models were performed: (1) all adults; (2) adults with a formal diagnosis of caries; and (3) adults without such caries. Self-perceived dental caries showed 77.7% sensitivity, 58% specificity, 65% accuracy, 52% positive predictive value, and 81% negative predictive value. In Model 1, self-perceived dental caries was associated with time of use of dental services, access to information, flossing, formal diagnosis of caries, self-perceived need for treatment, toothache, and dissatisfaction with oral health and general health. In Model 2, self-perceived dental caries was associated with time of use of dental services, self-perceived need for treatment, and dissatisfaction with oral health and general health. In Model 3, self-perceived dental caries was associated with time of use of dental services, access to information, flossing, self-perceived need for treatment, and dissatisfaction with oral health. Self-perceived dental caries showed limited utility as a diagnostic method.

    Full Text Available Dental caries levels in the Kingdom of Saudi Arabia have been a cause of concern to public health planners for sometime. The dental caries symposium of the 14th Makkah Dental Conference brought together leaders from the different academic and clinical stakeholders in the provision of dental health care in the Kingdom of Saudi Arabia. The aim of the symposium was to establish consensus on the role of different public health measures to be implemented in the Kingdom of Saudi Arabia that could help reduce the overall dental caries rate. This consensus statement summarizes the key findings of the panel and presents a consensus statement on six major topics: (1 water fluoridation, (2 dental health care provision by the Ministry of Health, (3 cost-effectiveness of preventive dental care, (4 caries risk assessment, (5 evidence-based recommendations for the prevention of dental caries, and (6 the role of the dental academic sector in the prevention of dental caries. These six factors were discussed in the background of international best practices in caries prevention and how these practices could be adopted in the Kingdom of Saudi Arabia.

    Alkali production by oral bacteria is believed to have a major impact on oral microbial ecology and to be inibitory to the initiation and progression of dental caries. A substantial body of evidence is beginning to accumulate that indicates the modulation of the alkalinogenic potential of dental biofilms may be a promising strategy for caries control. This brief review highlights recent progress toward understanding molecular genetic and physiologic aspects of important alkali-generating pathways in oral bacteria, and the role of alkali production in the ecology of dental biofilms in health and disease.

    We conducted a parallel group randomized controlled trial of children initially aged 2 to 3 y who were caries free, to prevent the children becoming caries active over the subsequent 36 mo. The setting was 22 dental practices in Northern Ireland, and children were randomly assigned by a clinical trials unit (CTU) (using computer-generated random numbers, with allocation concealed from the dental practice until each child was recruited) to the intervention (22,600-ppm fluoride varnish, toothbrush, 50-mL tube of 1,450 ppm fluoride toothpaste, and standardized, evidence-based prevention advice) or advice-only control at 6-monthly intervals. The primary outcome measure was conversion from caries-free to caries-active states. Secondary outcome measures were number of decayed, missing, or filled teeth (dmfs) in caries-active children, number of episodes of pain, and number of extracted teeth. Adverse reactions were recorded. Calibrated external examiners, blinded to the child's study group, assessed the status of the children at baseline and after 3 y. In total, 1,248 children (624 randomized to each group) were recruited, and 1,096 (549 intervention, 547 control) were included in the final analyses. Eighty-seven percent of intervention and 86% of control children attended every 6-mo visit ( P = 0.77). A total of 187 (34%) in the intervention group converted to caries active compared to 213 (39%) in the control group (odds ratio, 0.81; 95% confidence interval, 0.64-1.04; P = 0.11). Mean dmfs of those with caries in the intervention group was 7.2 compared to 9.6 in the control group ( P = 0.007). There was no significant difference in the number of episodes of pain between groups ( P = 0.81) or in the number of teeth extracted in caries-active children ( P = 0.95). Ten children in the intervention group had adverse reactions of a minor nature. This well-conducted trial failed to demonstrate that the intervention kept children caries free, but there was evidence that once

    The aims of this cross-sectional statistical study were to evaluate the association between obesity and dental caries and to assess the impact of food intake, oral hygiene and lifestyle on the incidence of dental caries in obese paediatric patients, analysed by Dual X-ray Absorptiometry (DXA). A sample of 96 healthy patients, aged between 6 and 11 years (mean age 8.58±1.43) was classified in relation to body composition assessment and McCarthy growth charts and cut- offs. Body composition analysis, to obtain body fat mass (FM) and body fat free mass (FFM) measurements, was determined by means of a DXA fan beam scanner. The subjects underwent dental examination to assess the dmft/DMFT, and completed a questionnaire on food intake, oral hygiene habits and lifestyle. The sample was subsequently subdivided into four groups: Group A (normal weight - caries-free), Group B (normal weight with caries), Group C (pre-obese/obese - caries-free), Group D (pre-obese/obese with caries). The statistical analysis was performed using SPSS software (version 16; SPSS Inc., Chicago IL, USA). Spearman's correlation was performed to evaluate the correlation between dmft/DMFT and FM%. The chi-square test was performed to assess the categorical variables, while the non-parametric Kruskal Wallis test and the Mann Whitney test were employed for the quantitive variables. Statististical significance was set at a P-value of 0.05. The preobese-obese children had higher indexes of dental caries than normal weight subjects, both for deciduous teeth (dmft 2.5 ± 0.54 vs 1.4 ± 0.38; p=0.030) and permanent teeth (DMFT 2.8 ± 0.24 vs 1.93 ± 1.79; p=0.039). The correlations between dmft/DMFT indexes and body composition parameters were analysed and a significant correlation between dmft/DMFT indexes and FM% was observed (p=0.031 for dmft, p=0.022 for DMFT). According to the data recorded, there was no statistically significant difference between Groups A, B, C and D in terms of food intake between

    Dental caries is a major public health problem in most industrialised countries, affecting 60% to 90% of school children. Community water fluoridation was initiated in the USA in 1945 and is currently practised in about 25 countries around the world; health authorities consider it to be a key strategy for preventing dental caries. Given the continued interest in this topic from health professionals, policy makers and the public, it is important to update and maintain a systematic review that reflects contemporary evidence. To evaluate the effects of water fluoridation (artificial or natural) on the prevention of dental caries.To evaluate the effects of water fluoridation (artificial or natural) on dental fluorosis. We searched the following electronic databases: The Cochrane Oral Health Group's Trials Register (to 19 February 2015); The Cochrane Central Register of Controlled Trials (CENTRAL; Issue 1, 2015); MEDLINE via OVID (1946 to 19 February 2015); EMBASE via OVID (1980 to 19 February 2015); Proquest (to 19 February 2015); Web of Science Conference Proceedings (1990 to 19 February 2015); ZETOC Conference Proceedings (1993 to 19 February 2015). We searched the US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization's WHO International Clinical Trials Registry Platform for ongoing trials. There were no restrictions on language of publication or publication status in the searches of the electronic databases. For caries data, we included only prospective studies with a concurrent control that compared at least two populations - one receiving fluoridated water and the other non-fluoridated water - with outcome(s) evaluated at at least two points in time. For the assessment of fluorosis, we included any type of study design, with concurrent control, that compared populations exposed to different water fluoride concentrations.

    Dental caries is one of the most common preventable childhood diseases; people are susceptible to this ailment throughout their lifetime. In the US, 90% of late adolescents and young adults have dental caries, while 94% of all dentate adults had evidence of treated or untreated coronal caries. Dental caries is often not self-limiting and without proper care can progress until the tooth is destroyed. In this paper, the etiology of dental caries is briefly introduced. It is followed by a thorough review of patents and literatures on the recent development of various novel technologies for the prevention and treatment of dental caries. Recent advances in anti-plaque agents, including chemoprophylactic agents, antimicrobial peptides, vaccines, probiotics/replacement therapy and sugar substitutes, and remineralization agents including fluorides and casein phosphopeptides are analyzed. TAKE HOME MASSAGE: Both the discovery of new anti-caries agents and the development of dentotropic delivery systems will be the future focus of this research field.

    Obesity and dental caries are increasing epidemics, especially among children and adolescents. This epidemiological observational cross-sectional study was conducted to assess the possible association between body mass index (BMI) and dental caries among 111,792 school children and adolescents in Jiangsu Province. We found that 13.14% participants of the study sample were overweight, and 7.37% were obese. The prevalence of dental caries was 12.95% in overweight and 7.89% in obese students. There were significant differences in caries prevalence by sex, region, age group, and BMI. Overweight and obesity statuses were associated with dental caries among the study population. BMI and dental caries present a continuous health problem. Thus, we recommend that oral health promotion be used for caries prevention and control.

Glucosyltransferase fragment (Gtf are also in other strains of Streptococcus such as Streptococcus anginosus, Streptococcus milleri which includes beta hemolysis. Genotypically B Streptococcus anginosus has genetic characteristics that are similar to Streptococcus mutans. The research objective was to determine the existence of Gtf B/C gene as a cause of caries in Streptococcus anginosus. The study was conducted in experimental laboratories with PCR technique by taking a sample of 20 children who had caries. The results showed there was the amplification of Streptococcus anginosus with a level of homology 96%, 97%, and 99%. The results of the Gtf genes amplification fragment B/C provided 600 pb ribbon. The conclusion was Streptococcus anginosus classified as cariogenic bacteria because they had Gtf B/C genes.

    The aim of the study was to assess the prevalence of dental fluorosis, dental caries, and associated risk factors in the school children of district Fatehgarh Sahib, Punjab, India, using a cross-sectional study design. Oral health status of children aged between 8 and 15 years was assessed using World Health Organization (WHO) 2013 criteria. Dental fluorosis was assessed using Dean's index, and dental caries were recorded using decayed, missing, filled/decayed, extracted, filled (DMF/def) indices. Four hundred school children were examined, of which 207 were in the 8-11-year-old group and 193 were in the 12-15-year-old group. The overall prevalence of dental fluorosis was 4.1%, which might be linked to a high concentration of fluoride in drinking water at certain locations of rural Punjab. The prevalence of dental caries was 36.5% with a mean DMF score of 0.3 and def score of 0.6. Risk factors for dental caries include oral hygiene behavior and sugar consumption patterns. The study highlights the need to increase awareness about the oral health and hygiene among the school children in India.

    The aim of the study was to investigate caries experience and dental care index in diabetic children and to determine if correlation exists between caries experience and metabolic control, insulin treatment, and the duration of diabetes. The study group consisted of 52 children and adolescents, 3-16 years of age with type 1 diabetes attending the outpatient diabetic clinic at Ghent University Hospital, Belgium. Fifty healthy subjects recruited from the paediatric dental clinic served as the control group. Caries lesions were assessed using DMF-index both at cavity and non-cavity levels. Participants and/or their guardians provided information about oral hygiene habits and dietary habits. Diabetes-related data (type, duration, insulin regimen) were collected from medical records and completed with the lab data on HbAlc. It became clear that, although children with type 1 diabetes mellitus could be expected to run a potential high caries risk taking into account the diabetes-associated biological and behavioural alterations, no significant differences were observed regarding caries experience and dental care between diabetic children and healthy controls. The level of untreated dental decay among the diabetic children is, however, considerably high, which was reflected by a significant lower dental attendance. © 2010 The Authors.

    Dental hygienists do not legally (or definitively) diagnose caries, but they often are responsible for preliminary interpretation of bitewing (BW) radiographs taken during prophylaxis appointments. Given this custom of practice, it is important to understand whether there is a difference between the capabilities of dental hygienists and dentists in interpreting BWs based on education and clinical experience. This study compared proximal carious lesion classification from BWs by senior dental students and senior dental hygiene students. Volunteers (40 dental [D] and 54 dental hygiene [DH] students) classified proximal carious lesions from BWs of 96 extracted teeth, which were mounted in wax to simulate quadrants of the mouth. A soft tissue equivalent was placed in front of the mounted teeth before x-ray exposure. Films were developed automatically and mounted into six sets point scale. The teeth were sectioned vertically and evaluated clinically at 5x magnification with an explorer. The "gold standard" of carious lesion classification was then compared to the students' classifications. All students detected 54% of the carious lesions and correctly identified lack of caries 80.5% of the time. There were no differences between the two groups of students in terms of sensitivity, but dental students showed higher specificity (p = 0.0006). Permitting dental hygienists to make preliminary interpretations of caries from BWs in the dental office appears to be an acceptable practice.

    Full Text Available Objective: There are various risk factors which play an essential role in the multifactorial disease “dental caries.” Although absence of interdental spaces in the primary dentition may increase the risk of dental caries, not many studies have been carried out to assess this correlation. This study was performed to assess the relationship between interdental spacing and dental caries in primary dentition.Materials and Methods: Five hundred 4-6 year-old children were enrolled into this study. Dental caries was recorded using the criteria given by Warren et al. Following this, impressions were made for the upper and lower arches and dental casts were poured. Interdental spaces were measured on the dental casts using a digital verniercaliper. The data obtained were subjected to statistical analysis.Results: The number of sites with interdental spaces was higher in the maxillary arch in comparison to the mandibular arch. The highest number of interdental spaces was observed between the maxillary anteriors. The number of demineralized, but non-cavitated tooth surfaces (d1were higher than the number of cavitated tooth surfaces. This difference was significant in the mandibular anterior segment. Dental caries showed a negative correlation with interdental spacing. A significant correlation was found between dental caries and interdental spacing in the posterior segment of the mandibular arch.Conclusion: This study showed that children with no interdental spacing in the primary dentition are at higher risk for dental caries.Key Words: Dental Caries; Interdental Spaces; Interproximal Caries

    A pathfinder pilot survey was conducted in rural Chiriqui Province, Panama, using standard WHO methodology, in order to estimate dental caries prevalence and treatment need. Examinations for caries and treatment need were performed by six trained, experienced examiners. From a convenience sample of 2,597 subjects, a stratified cluster sample was constructed using index ages 12 and 15 years and age groups 35-44 and 65-74 years. The results showed a mean Decayed, Missing and Filled Teeth index (DMFT) of 4.08 for 12 year olds, 6.40 for 15 year olds, 13.20 for the 35-44 age group, and 18.88 for the 65-74 age group (P Mexico and Haiti when compared to the results of other Central American community studies. The percentage of caries free 12 year olds was 6.8 per cent. Of the total sample, 74.7 per cent of individuals would require one or multiple surface restorations and 47.9 per cent would require at least one extraction. Restorative need was greatest in the 15 year olds. The severity of dental caries in this sample was moderately severe and the treatment need extraordinarily high.

    Full Text Available Los factores de riesgo asociados con la caries dental constituyen una probabilidad medible y tienen valor predictivo en la prevención de esta enfermedad que la sitúa como la principal causa de pérdida dentaria. Se realizó un estudio observacional descriptivo de corte transversal para determinar el comportamiento clínico epidemiológico de los factores de riesgo de la caries dental en niños de círculos infantiles del municipio Artemisa entre abril y diciembredel 2007, con la finalidad de identificar la prevalencia y factores de riesgo asociados con la caries dental y analizar el grado de riesgo en la muestra objeto de estudio. El universo de trabajo estuvo formado por 642 infantes pertenecientes a 6 círculos infantiles y la muestra se realizó por factibilidad, en la cual se seleccionaron 2 círculos infantiles para un total de 240 infantes, los cuales se agruparon atendiendo a la edad, sexo, prevalencia de caries dental y factores de riesgo mayormente asociados, así como el grado de riesgo. Se realizó un formulario que incluía el interrogatorio a padres y/o tutores y el examen bucal a los niños en las mismas instituciones, aplicando en cada caso el índice ceo-d. Entre los principales resultados se destaca, que el 80 % de los niños se encontraban libres de caries, que los factores de riesgo que más incidieron fueron la dieta cariogénica y la higiene bucal deficiente y que más del 80 % de la muestra posee un bajo riesgo a caries. Se concluye que la prevalencia de caries dental en estas instituciones es baja, a pesar de la influencia de factores de riesgo que condicionan la aparición de la enfermedad.Risk factors associated to dental caries are a measurable likelihood and also a predictive value in prevention of this condition, which is the major cause of teeth loss.

    Full Text Available Dental caries still remain as the most prevalent oral health disease in children. Many efforts have been done to prevent dental caries in children, but unfortunately there are dental practitioners who still have false mindset and prefer not to treat the dental caries case in primary teeth with the most common reasons are because it will be replaced with the permanent teeth. There are many negative effect will occur if the dental caries treatments in primary teeth are neglected.This topic would review the effects of untreated dental caries in children based on research reports.Severely decayed teeth have an important impact on children’s general health, nutrition, growth and body weight by causing discomfort, pain, sleeping problems, learning disorders and absence from school.  Untreated caries may affect seriously the quality of children’s life because of pain and discomfort, which could lead to acute and chronic infections, oral mucosal conditions and altered eating and sleeping habits. Furthermore, untreated caries in primary teeth can have a lasting detrimental impact on the permanent dentition by causing high caries risk or developmental defects of the permanent successor tooth. Moreover it has been reported that children at each higher level of caries had significantly lower height and weight outcomes than those with lower caries levels. The untreated dental caries in primary teeth would lead the children to poor growth and health which lowering the their quality of life.

    Full Text Available Objective: The aim of the present study was to evaluate the efficacy of two caries detector dyes in the diagnosis of dental caries.Materials and Methods: Twenty extracted human posterior teeth without pulpal exposure were sectioned mesiodistally through the center of the lesions using a water-cooled disk.The tooth halves were randomly divided into two groups and treated with Caries Detector (CD and Caries Check (CC detector dyes. Access cavities were prepared followed by caries removal and dye application. All cavities were arbitrarily divided into two right and left sections and excavation of the stained areas was performed on the left parts, while the right sections remained untouched. Bacterial penetration into dentinal tubules was evaluated using Gram-stained decalcified sections under light microscopy. Sensitivity and specificity of both dyes were calculated.Results: The sensitivity of CD and CC were 74% and 71%,respectively. The specificity obtained for both dyes was 100%.Conclusion: Considering the low sensitivity of the dyes evaluated in the present study, it seems that they may not be reliable when used as the sole diagnostic technique for detection of carious lesions in posterior teeth.

    Various models have been used to study the accuracy of imaging systems for detection of dental caries. This study compares the ability of dentists to detect mechanically created defects versus natural dental caries cavitations on the proximal surfaces of extracted teeth with Computed Dental Radiography (Schick Industries, Long Island City, N.Y.). Detection rates are investigated according to lesion depth to permit comparisons to be made between studies in the literature with other mechanical defects or natural caries models. Discrimination of natural caries versus artificial defects with Computed Dental Radiography is also compared with a previous report that used standard dental film. Fifty-two extracted molar and premolar teeth were mounted into representative sets of maxillary and mandibular posterior arches for bite-wing radiography. There were 16 proximal surfaces with natural caries and 28 proximal surfaces with mechanical defects. An optical bench was used to ensure constant beam geometry. A 1.8 cm acrylic soft tissue equivalent attenuator was placed in front of the receptor. Thirty dentists acted independently as observers to differentiate between sound proximal tooth surfaces, natural dental caries, and mechanical defects. Evaluation of intra- and interobserver variability was made with use of the kappa statistic. The Zelen test of odds ratios was used to test for homogeneity, and the Mantel-Haenszel analysis plus stratified logistic regression were used for inference about the common odds ratio. Significance was set at p detection was 74% for mechanical defects and 67% for natural caries. The odds of detecting a mechanical defect were 1.40 times the odds of finding natural dental caries cavitation of the same depth. Lesion depth did influence the probability of correctly identifying the presence of a lesion; the odds of identifying cavitation increased 1.41 times with every 0.1 mm increase in lesion depth. Correct designation of lesion type was 1.42 times

    Candida albicans may have cariogenic potential but its role in caries etiology has not been established. The aim of this study was to determine candida albicans in supragingival dental plaque and infected dentine of cervical and proximal in early childhood caries (ECC). This cross-sectional study was carried out on 6o children aged 2-5 years, which were divided into 3 groups: children with at least one cervical caries; children with at least one proximal caries and caries-free. The infected dentine was collected from cervical and proximal caries lesions and plaque samples were collected from the three groups in order to compare the frequency of candida albicans in the collected sites. All samples were cultured in Sabouraud and CHROMagar medium and the cases that were positive for candida albicans were cultured in germ tube. Data were collected and analyzed. The mean age of the children was 3.9 years. From 100 samples, candida albicans samples were isolated in 55%, mold fungi were found in 29% cases and there was no fungal growth in 16% of the samples. In plaque samples, candida albicans were found in 15% of caries-free samples, 20% of the proximal and 80% of the cervical caries. In samples extracted from the caries, candida albicans were found in 60% of the proximal and 100% of the cervical caries. Mothers with university educational level had children with more cervical decays, caries free and proximal caries, respectively. The results showed that prevalence of Candida albicans in dental plaque and caries lesions of children with early childhood caries were relatively high and the prevalence was higher in cervical caries group.

    Insulin dependent diabetes mellitus is a severe disease that raises blood glucose levels because of hyperglycemia and insulinopenia. Fluctuations in water and electrolyte levels may result in xerostomia and other changes in the salivary composition. Since diabetes has an influence on oral health, it is important for the dentist to be aware of newer advances in the field of diabetes and to recognize specific oral problems related to diabetes. Thus, the dentist becomes an important part of the health care team for the patients with diabetes. The present study correlated salivary flow rate, salivary pH and total salivary antioxidant levels and dental caries in type I diabetic patients. A total of 200 children that included 100 known diabetic children (study group) and 100 healthy children (controls) of both the sexes and from similar socioeconomic backgrounds formed the part of this study. Dental caries was assessed using DMFT index. The salivary total anti-oxidant level was estimated using phospho molybdic acid using spectrophotometric method. The salivary flow rate was recorded using the Zunt method and the salivary pH using the pH indicating paper. The results were statistically analyzed using t-test. The analyzed parameters showed increase in salivary anti-oxidant levels, reduced salivary flow rate, increase incidence of dental caries, salivary pH was decreased when compared to the control group.

    Full Text Available The study of twins provides a unique opportunity to evaluate the genetic and nongenetic contributions to a variance of multitude of traits. Twin research has revealed the impact of a strong genetic component to the variance of many dental traits. The present study was conducted to assess the dental caries and oral hygiene status in monozygotic (MZ and dizygotic (DZ twins. A random sample of 129 MZ and DZ twin pairs aged 6-15 years were included in this study. The zygosity of twin pairs was initially recorded by facial appearance and later determined by dermatoglyphics. Dental caries and oral hygiene status were recorded in these twin pairs and the data were subjected to statistical analysis. No significant difference was observed in the mean decayed, extracted due to caries and filled teeth (deft in primary dentition and decayed, missing and filled (DMFT in permanent dentition scores and oral hygiene status in MZ and DZ twin pairs. The similarity observed in oral health status reflects the effects of a shared environment in MZ and DZ twin pairs.

  19. Exposure to metal ions and susceptibility to dental caries.

    Results from several epidemiologic studies have shown that there are large differences in the prevalence of dental caries from one region to another within the United States as well as in other countries. It has been postulated that the observed differences may be attributed in part at least to exposure to trace elements such as selenium, vanadium, molybdenum, strontium, and lead. Although data from epidemiologic studies usually support this hypothesis, direct evidence is sparse with the possible exception of exposure to lead. Data from several epidemiologic studies and animal-based research support the concept that lead is a caries-promoting element. Lead mimics calcium in several respects and may affect development of teeth and salivary glands, clearly enhancing susceptibility to dental caries. Elevated blood levels are found most commonly in persons residing in inner cities, particularly among the poor. Many states require blood lead level to be monitored in young children. Where feasible, these records should form part of health history and be available to the treating dental practitioner to ensure that extra preventive procedures may be implemented.

    To compare the diagnostic accuracy of Kodak Insight film with other intra-oral films in the detection of dental caries. Periapical radiographs of 99 extracted human teeth with sound proximal surfaces and interproximal artificial cavities were made on Kodak Ultra speed, Ektaspeed, Agfa Ektaspeed and Kodak Insight films and automatically processed. Six dentists examined the presence of dental caries using a five-point confidence rating scale and compared the diagnostic accuracy by ROC (Receiver Operating Characteristic) analysis and ANOVA test. The sensitivity of Kodak Ultra speed, Ektaspeed, Agfa Ektaspeed and Insight film were 0.84, 0.77, 0.75 and 0.79 respectively. The specificity of Kodak Ultra speed, Ektaspeed, Agfa Ektaspeed and Insight film were 0.97, 0.95, 0.96 and 0.94 respectively. The mean ROC areas (Az) of Kodak Ultra speed, Ektaspeed, Agfa Ektaspeed and Insight film were 0.917, 0.910, 0.894, 0.909 respectively. There was no significant differences between Az of Insight film and other films (p = 0.178). Theses results suggested that Kodak Insight film have the comparative diagnostic accuracy of dental caries with Ultraspeed and Ektaspeed films. (77)

    This cross-sectional study assessed the prevalence and severity of the enamel defects, known as Molar-Incisor Hypomineralization (MIH) and its relationship to dental caries. A sample of 1157 schoolchildren (population based), aged 6-12 years, of the Araraquara city-Brazil, was evaluated according to the European Academy of Paediatric Dentistry (EAPD) criteria by two trained examiners. The dental impact caused by MIH was evaluated with the Decayed, Missing and Filled Teeth (DMFT) index (WHO). Data were analyzed using ANOVA and Chi-square tests (p < 0.05). The socioeconomic status was collected using a questionnaire answered by parents. The prevalence of MIH was 12.3%. Mild impairment was the most frequent diagnosis. DMFT of children with MIH was 0.89 (± 1.18), which are higher than those of the unaffected group (0.43 ± 1.01). An association was found between dental caries only in the permanent dentition of children with MIH (p = 0.0001). Family income was considered low in 85% of the families of children with MIH in the public system, while in private school it was 18% (p < 0.05). The prevalence of MIH in Araraquara was associated with greater caries experience in the permanent dentition.

    To determine the efficacy of salivary nitric oxide as a biomarker for dental caries risk in children and to compare the salivary nitric oxide levels in caries-active and caries-free children. One hundred children aged 6-12 years were selected and were divided into two groups according to DMFT index: as caries-free consisting of 50 individuals (DMFT/dmft = 0) and caries-active group (DMFT/dmft ≥3) consisting of 50 individuals. The saliva collected was estimated for nitric oxide level by Griess reaction method. Paired t test was used to correlate the difference of mean salivary nitric oxide levels between caries-active and caries-free groups. The mean level of nitric oxide in saliva of the control group was 581.3 ± 134.6 μg/mL and that of caries-active group was 335.4 ± 111.1 μg/mL, respectively. The mean salivary level of nitric oxide was higher in the caries-free group as compared with the caries-active group which was statistically significant (p = 0.000). Salivary nitric oxide was higher in the caries-free group as compared to the caries-active group which suggests that increased production of nitric oxide in the oral cavity may contribute to lower caries incidence in children.

    Full Text Available Introduction: Dental caries is the most prevalent disease among mentally handicapped (MH children worldwide. Dental neglect may throw light on complex relationships between individual behavior, environmental factors, and dental caries in children. Objectives: The objective was to assess the prevalence and severity of untreated dental caries and to explore the relationship between untreated dental caries and dental neglect among MH children and healthy children in Bangalore city. Materials and Methods: A cross-sectional comparative study was conducted on 130, 6-17 years MH and 152 healthy school children in Bangalore city. A questionnaire on the children′s sociodemographic background, oral health-related behaviors, and dental neglect scale was completed by the parents. Caries was assessed according to World Health Organization criteria (1997. Odontogenic infections were recorded using the pufa/PUFA index. Statistical tests such as Mann-Whitney U-test, Chi-square test, Spearmans correlation, and step-wise linear regression were performed at significance level P < 0.05. Results: Dental caries was present in 89.2% of MH children as compared with 88.15% of the healthy children. Caries experience significantly correlated with consequences of untreated dental caries in both the groups (P = 0.001. No statistical significant correlation was observed between dental neglect and dental caries experience and its consequences in both the groups. Conclusions: High prevalence of dental caries and dental neglect in both the groups calls for an integrated approach. Oral health promotion and intervention programs should be targeted and concentrated toward these risk groups.

    We investigated the association between antipsychotic medications and the risk of dental caries in patients with schizophrenia. We enroled a nationwide cohort of patients with newly diagnosed schizophrenia within 1 year of dental caries development. Exposure to antipsychotics and other medications was categorised according to their type and duration, and the association between exposure and dental caries was assessed through logistic regressions. Of the 3610 patients with newly diagnosed schizophrenia, 2149 (59.5%) exhibited an incidence of treated dental caries. Logistic regression analysis identified a younger age, female sex, high income, a 2-year history of dental caries, and exposure to first-generation antipsychotics, and antihypertensives as independent risk factors for treated dental caries in patients with schizophrenia. Hyposalivation, the adverse effect of first-generation antipsychotics and antihypertensives, was associated with an increased risk of treated dental caries. However, hypersalivation from first-generation antipsychotics for dental caries was associated with a protective factor. These findings suggest that clinicians should pay attention to the aforementioned risk factors for dental caries in patients with schizophrenia, particularly while prescribing first-generation antipsychotics and antihypertensives to such patients.

    Research has demonstrated the validation of specific caries risk assessment (CRA) systems, but little is known about how dental practitioners assign a caries risk level to their patients. The aim of this study was to explore dental students' decision making in caries risk assignment when using the Caries Management By Risk Assessment (CAMBRA) system. Multiple correspondence analysis and chi-squared automated interaction detector analysis were performed on data collected retrospectively for a period of six years (2003-09) at the University of California, San Francisco predoctoral dental clinic. The study population consisted of 12,952 patients from six years of age through adult who received a baseline CRA during the period, were new to CAMBRA, and had not received any prior CAMBRA recommendations. The results showed variation in decision making and risk level assignment, illustrated by the range of percentages for the three scores (low, moderate, and high/extreme caries risk) when CRA was assigned for the first time. For those first-time CRAs, decision making was mainly based on four factors: cavities or caries lesions into dentin on radiograph, restorations during the last three years due to caries, visible heavy plaque, and interproximal lesions into enamel (by radiographs). This study's findings provide important data regarding one group of CAMBRA users and thus contribute to the development of knowledge about the implementation of caries risk assessment in contemporary dental practice.

    China has 55 ethnic minority groups comprised of 113 million persons, or 7.0% of total population. Dental caries is a major health problem for children in China, and national oral health surveys currently report dental caries based on geographical location rather than by ethnic group. This study reviews the literature on dental caries in ethnic minority children in China. Publications were retrieved in Chinese and English from five electronic databases; thirty-eight studies from 1983 to 2012 met inclusion criteria and described 25 ethnic minority groups. Primary dentition median caries prevalence and experience were higher (51% and dmft = 3.0, respectively) than permanent dentition caries prevalence and experience (39% and DMFT = 0.8). Median caries prevalence was highest (80%) for permanent dentition among aggregated ethnic minorities with population greater than 1 million. More work and research is needed to expand dental caries prevention and treatment measures for ethnic minority child populations in China.

    Salivary secretory IgA (sIgA) is said to play an important role in the immune response against dental caries. This study aimed to determine the salivary sIgA levels in healthy smokers and non-smokers, and its correlation with dental caries. A total of 70 healthy subjects were selected and classified into four groups according to dental caries and tobacco smoking habits: smoking with caries (Group 1, n = 15); smoking without caries (Group 2, n = 15); non-smoking with caries (Group 3, n = 15); and non-smoking without caries (Group 4, n = 25). Salivary sIgA was measured using ELISA. The fissure and proximal caries were examined clinically and radiographically. Caries status was determined according to the decay surface index. Smokers showed a higher number of caries and the lowest concentration of sIgA. The highest levels of sIgA were observed in non-smoking and caries-free subjects compared to caries-active smokers (123.2 ± 19.9 vs. 13.3 ± 4.1 μg/ml respectively, p caries in smokers. © 2013 Australian Dental Association.

    Full Text Available Dependence on drugs is a complex disease, incurable and that its use persists in the face of extremely negative consequences. Objective: was to evaluate the prevalence and severity of caries in users of legal drugs. Methods:It is an epidemiological, cross-sectional, descriptive study, held with adults, users of legal and illegal drugs, institutionalized in rehabilitation centers of municipalities in the southwestern region of the state of Bahia. We used a form with sociodemographic questions about the use of licit and illicit drugs. To assess tooth decay, we used the decayed, missing and filled teeth index (DMFT, and the dental units were assessed with a World Health Organization (WHO Model probe and a dental mirror. Data were tabulated and analyzed in Excel. Results: 73 individuals were evaluated, aged between 18 and 64, mean age 35.5 (SD ± 10.7. It was found that 71.4% are single, 73,7% with low level of education, 74.6% do not use dental floss. Caries prevalence was 98.6%, DMF-T average 15.6. In 18-34 years old individuals, the DMF-T average was 12.1 and from 35 to 64 years old it was 19.8. Regarding dentition, 52.6% of the teeth were affected by the disease. Among the affected teeth, 39.9% were decayed, 44.1% lost and 16% filled. Conclusion: We conclude that there is a high prevalence of caries in this population. Among the dental needs, the restoration of the dental element has to be highlighted.

    While national surveys have found that African-Americans have a higher prevalence and severity of dental caries than white-Americans, there are only a few descriptive studies of the prevalence and severity of dental caries in low-income urban African-Americans. This study assessed the prevalence, severity and determinants of dental caries, using the International Caries Detection and Assessment System (ICDAS). A representative sample of low-income families (a caregiver and a child aged 0-5 years) was selected from low-income census tracts in the city of Detroit, Michigan. Of the 12,655 randomly selected housing units, 10,695 were occupied and 9781 were successfully contacted (91.5%). There were 1386 families with eligible children in the contacted households; and of those, 1021 were interviewed and examined at a permanent examination center organized for this study. This represents an overall response rate of 73.7%. At the center, trained staff interviewed the main caregivers of the selected children, and trained and calibrated dentists examined the caregiver and her/his child. Data used in this study included information gathered from the social, behavioral and parenting questionnaires, the Block Food Frequency Questionnaire (total sugar intake), and data collected from community and census databases. Over 90% of the adults (ages 14-70 years, average 29.3) had at least one noncavitated carious lesion and 82.2% had at least one primary cavitated lesion. Negative binomial regression models found that the age of caregivers and the number of churches in neighborhoods were negatively associated with the number of noncavitated tooth surfaces. Cavitated tooth surfaces were positively associated with age, oral hygiene status, being worried about teeth, a recent visit to a dentist, and the number of grocery stores in the neighborhoods. However, the number of cavitated tooth surfaces was negatively associated with preventive dental visits, positive rating of oral health

    In recent years, unprecedented gains in the understanding of the biology and mechanisms underlying human health and disease have been made. In the domain of oral health, although much remains to be learned, the complex interactions between different systems in play have begun to unravel: host genome, oral microbiome with its transcriptome, proteome and metabolome, and more distal influences, including relevant behaviors and environmental exposures. A reasonable expectation is that this emerging body of knowledge can help improve the oral health and optimize care for individuals and populations. These goals are articulated by the National Institutes of Health as "precision medicine" and the elimination of health disparities. Key processes in these efforts are the discovery of causal factors or mechanistic pathways and the identification of individuals or population segments that are most likely to develop (any or severe forms of) oral disease. This article critically reviews the fundamental concepts of risk assessment and outcome prediction, as they relate to early childhood caries (ECC)-a common complex disease with significant negative impacts on children, their families, and the health system. The article highlights recent work and advances in methods available to estimate caries risk and derive person-level caries propensities. It further discusses the reasons for their limited utility in predicting individual ECC outcomes and informing clinical decision making. Critical issues identified include the misconception of defining dental caries as a tooth or surface-level condition versus a person-level disease; the fallacy of applying population-level parameters to individuals, termed privatization of risk; and the inadequacy of using frequentist versus Bayesian modeling approaches to derive individual disease propensity estimates. The article concludes with the notion that accurate caries risk assessment at the population level and "precision dentistry" at the

    The purpose of this study was to evaluate the effectiveness of xylitol in reducing dental caries in children compared to no treatment, a placebo, or preventive strategies. MEDLINE via PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched from January 1, 1995 through Sept. 26, 2016 for randomized and controlled trials on children consuming xylitol for at least 12 months. The primary endpoint was caries reduction measured by mean decayed, missing, and filled primary and permanent surfaces/ teeth (dmfs/t, DMFS/T, respectively). The I2 and chi-square test for heterogeneity were used to detect trial heterogeneity. Meta-analyses were performed and quality was evaluated using GRADE profiler software. Analysis of five randomized controlled trials (RCTs) showed that xylitol had a small effect on reducing dental caries (standardized mean difference [SMD] equals -0.24; 95 percent confidence interval [CI] equals -0.48 to 0.01; P = 0.06) with a very low quality of evidence and considerable heterogeneity. Studies with higher xylitol doses (greater than four grams per day) demonstrated a medium caries reduction (SMD equals -0.54; 95 percent CI equals -1.14 to 0.05; P = 0.07), with these studies also having considerable heterogeneity and very low quality of evidence. The present systematic review examining the effectiveness of xylitol on caries incidence in children showed a small effect size in randomized controlled trials and a very low quality of evidence that makes preventive action of xylitol uncertain.

    The aim of this study was to verify whether socioeconomic determinants, such as parents' educational level, family income and dental service attendance by children, are associated with the presence of caries among an Italian population of children. An observational retrospective study was carried out in a population of children aged 4-14 years who visited the Paediatric Dentistry Department of the University of Perugia, Italy. Children were stratified according to familial socioeconomic level (father's and mother's educational level, family income) and dental service attendance of children. Age- and sex- adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated by means of multivariate logistic regression models. A sample of 231 children (mean age 8.1 yrs, SD 2.6; 127 males, 104 females) was recruited. One hundred and sixty three (70.46%) children in the study had caries. Caries presence in children was higher in children where the mothers' educational level was lower (OR =6.1; 95% CI = 3.1 to 12.7), in children where the fathers' educational level was lower (OR =2.9; 95% CI =1.6 to 5.5) and in children with lower family income (OR = 9.9; 95% 95% CI = 5.1 to 20.1). No statistically significant difference were observed in terms of caries presence between the children who were visited at least once by a dentist and children who were not previously seen by a dental practitioner (OR = 0.8; 95% CI = 0.4 to 1.6). Socioeconomic level was an important predictor of caries presence among children. Both low income and low parental educational level were related to an increased presence of caries, whereas previous dental visits experience did not affect caries presence in children.

    Dental caries has a significant impact on the general health and development of children. Understanding caries epidemiology is an essential task for the United Arab Emirates (UAE) policymakers to evaluate preventive programmes and to improve oral health. The purpose of this review is to collect and summarise all data available in the published literature on the epidemiology of dental caries in the UAE in children aged under 13 years. This will provide dental health planners with a comprehensive data summary, which will help in the planning for and evaluation of dental caries prevention programmes. Data were collected from the various published studies in PubMed, Academic Search Complete, Google, and the reference lists in relevant articles. Four keywords were used in the search: 'dental caries,' 'epidemiology,' 'prevalence,' and 'UAE'. All studies conducted in the UAE in general or any single emirate that sheds light on the prevalence of dental caries of children under 13 years were included in this literature review. Studies on early childhood caries and factors associated with dental caries were also included. The review comprises 11 published surveys of childhood caries in UAE. The earliest study was published in 1991 and the most recent was published in 2011. The range of decayed, missing and filled primary teeth (dmft) in UAE children (age between 4 years and 6 years) was 5.1-8.4. For the 12-year-old group the decayed missing and filled permanent teeth (DMFT) ranged from 1.6 to 3.24. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate goals and planning for preventive oral health programmes. The current data available on the dmft and DMFT indicate that childhood dental caries is still a serious dental public health problem in the UAE that warrants immediate attention by the government and policy makers. © 2014 FDI World Dental Federation.

    Objective: Dental caries remains a public health problem, particularly among socially deprived populations. In some developing countries, salt fluoridation programmes have been recently developed, but the use of fluoridated salt is limited worldwide and the level of evidence for its efficacy remains debated. Method: A literature review was conducted to identify epidemiological or clinical studies that have evaluated the effect of salt fluoridation on dental caries experiences in children. Results: After a literature search, 22 references were selected reporting data on the preventive effect of salt fluoridation programmes in Europe (Hungary, Switzerland, France, Germany) and South and Central America (Colombia, Mexico, Jamaica...). Data were mainly obtained from descriptive or retrospective epidemiological studies. The results indicate that, in the absence of topical fluoride support, salt fluoridation leads to a significant reduction in caries indexes among treated children compared to a control group. In a context of widespread use of fluoridated toothpastes, the additional effect achieved by salt fluoridation is limited. The prevalence of fluorosis is not markedly increased with fluoridated salt, but side effects were not always evaluated. Conclusion: Today, a salt fluoridation programme could be useful in areas in which fluoridated toothpastes are not widely used. The communication policy promoting the consumption of fluoridated salt is crucial to ensure the effectiveness of such a programme.

    Objectives India is unique in entire world due to variety of dietary habits in population. Many people of India follow totally vegetarian life style through their entire life time due to some religious and cultural reasons. Present study tried to analyze the role of different factors in the occurrence of dental caries including dietary habit. Methods Persons suffering with dental caries were examined for the type of dental caries in relation to different factors. Dental examination was performed and patients were asked a questionnaire and the data was recorded and analyzed. Results Incidence of dental caries was higher in female. High number of dental caries patients was observed among vegetarian population. 21–30 year age group was found to be most infected with dental caries. Conclusions This study can be helpful to analyze respective role of different dietary factors including protein rich diet, age, gender etc. on the prevalence of dental caries, which can be helpful to counteract the potential increase in the cases of dental caries and to design and plan preventive strategies for the persons at greatest risk.

    Full Text Available Aim: The aim of the present study was the evaluation of non-microbial salivary caries activity parameters and salivary biochemical indicators in predicting dental caries. Materials and Methods: The present study was carried out on 60 children, aged 4-6 years, selected from the schools of Panchkula district, Haryana, on the basis of their caries status. Level of hydration, flow rate, pH, buffering capacity, relative viscosity, calcium, phosphorus and alkaline phosphatase levels in caries-free and caries-active children were evaluated. Results: Results showed that 90% of subjects in the caries-free group and 30% of subjects in the caries-active group had normal level of hydration value of less than 60 s and the difference was found to be statistically very highly significant. Normal flow rate of stimulated saliva was found in 90% of the subjects in caries-free group and 33.3% subjects in the caries active group and difference was found to be statistically very highly significant. Adequate salivary pH was found in 100% subjects in caries-free group and 30% in caries-active group and the difference was statistically very highly significant. Conclusion: To conclude, within limitations of this study, it became clear that normal level of hydration and higher values for flow rate, pH, buffering capacity of saliva lead to good oral health and a reduced caries occurrence. Increased salivary viscosity plays a role in increasing caries incidence. Salivary biochemical indicators like calcium, phosphorus and alkaline phosphatase also play their respective role in determining caries susceptibility of an individual. These salivary parameters can be used as diagnostic tool for caries risk assessment.

    Full Text Available A pesar de ser la caries dental una de las enfermedades más prevalentes en el ser humano, la Odontología no ha sido capaz todavía de establecer unos estándares para su diagnóstico y tratamiento; la decisión de cuándo y cómo obturar un diente afectado por caries dental está sujeta a una gran variabilidad. Se realiza una revisión bibliográfica con el objetivo fundamental de profundizar en los conocimientos teóricos y prácticos sobre tratamientos preventivos, curativos no invasivos e invasivos utilizados contra esta enfermedad. Se concluye que se deben potenciar los factores remineralizantes y solo cuando una lesión es activa, debe ser obturada, y que las nuevas técnicas de Biología Molecular pueden acelerar las conquistas de vacunas sintéticas.In spite of being dental caries one of the most prevailing lesions in individuals, Odontology has not yet been able to set some standards for its diagnosis and treatment since the decision of how and when a tooth with caries should be sealed shows great variability. A literature review was made to delve into the theoretical and practical knowledge on preventive and invasive and non-invasive curative treatment used in this type of illness. It was concluded that re-mineralizing factors should be potentiated, an active lesion is the only one that must be sealed and that new Molecular Biology techniques can accelerate the obtaining of synthetic vaccines.

    Full Text Available The prevalence of asthma has been increasing since the 1980s. Asthma and tooth decay are the two major causes of school absenteeism. There are few studies present in the literature. The objectives of the present study were to know the severity of dental caries and periodontal problems in children before and after taking antiasthmatic medication. The present study was conducted on 105, six- to fourteen-year-old asthmatic children to determine the condition of their dental caries and their periodontal status before and after taking antiasthmatic medication, for a period of 1 year and these were matched with their controls. The results showed that salbutamol inhaler shows increased caries rate with high significance over other groups, which was followed by salbutamol tablets and beclamethasone inhaler respectively. It has been concluded that antiasthmatic medication has its effects on dental caries and periodontal disease and asthmatic patients are recommended to adopt more precautionary oral hygiene practices and keep their caries activity and periodontal health under constant check.

    Socioeconomic position (SEP) is inversely associated with most oral health outcomes, but the patterns of association may vary depending on the specific outcome. We estimated associations between SEP and two oral health outcomes, dental caries and traumatic dental injuries (TDI), in Quebec children. We used data from the baseline visit of the QUALITY (QUebec Adipose and Lifestyle Investigation in Youth) Cohort, an ongoing study in Montreal and Quebec, Canada. The analytical sample included 590 children aged 8-10 years. Data on parents' SEP (household income, education) and children's health behaviours and involvement in sports were obtained through questionnaires and interviews. Oral health outcomes (dental caries and TDI in permanent teeth) were assessed by clinical oral exam. Negative binomial regression was used to model dental caries (DMFS index) and number of teeth with TDI adjusting for selected covariates. The mean (SD) DMFS and number of TDI were 0.61 (1.43) and 0.12 (0.43), respectively. Compared to the upper quartile of income, children in the lower quartile had a DMFS approximately 3 times higher (PRR=2.68, 95% CI: 1.43, 5.04). Adjusting for oral health and nutritional behaviours had no effect. Conversely, children in the highest income quartile had a 3 times higher number of teeth with TDI compared to the lowest quartile (PRR=3.14, 95% CI: 1.22, 8.08). Physical activity did not explain this relationship. Parents' education was not associated with dental caries or TDI. SEP seems to play a different role in the cause of dental caries and TDI.

    Iron deficiency anemia accounts for 90% of all types of anemia in the world. Although the prevalence has declined in recent years, it remains an important pediatric public health problem. Iron deficiency has also been associated with dental caries. It impairs salivary gland function causing reduced salivary secretion and buffering capacity leading to increased caries activity. The aim of the study is to explore an association between dental caries and serum levels of iron and ferritin in children aged 3-12 years. Subjectsand Methods: The study group included 120 children, hospitalized for uncomplicated medical problems. Blood reports were evaluated to determine serum iron and ferritin levels. Dental caries experience was assessed using deft index. The collected data were tabulated and analyzed using Student's t-test and Pearson's correlation coefficient. Out of 120 children, 38 children showed low serum iron levels of which 31 children had dental caries and nine out of 15 children in the high serum iron level group showed dental caries. High ferritin levels were seen in three children among which two children were caries-free and only one child had a low ferritin level who also had a positive deft score. Based on the results, it was concluded that there is an inverse association between serum iron levels and dental caries whereas there is no association between serum ferritin levels and dental caries.

    Dental caries is an oral pathology associated with both lifestyle and genetic factors. The caries process can be influenced by salivary composition, which includes ions and proteins. Studies have described associations between salivary protein polymorphisms and dental caries experience, while others have shown no association with salivary proteins genetic variability. The aim of this study is to assess the influence of salivary protein polymorphisms on the risk of dental caries by means of a systematic review of the current literature. An electronic search was performed in PubMed, Scopus, and Virtual Health Library. The following search terms were used: "dental caries susceptibility," "dental caries," "polymorphism, genetics," "saliva," "proteins," and "peptides." Related MeSH headings and free terms were included. The inclusion criteria comprised clinical investigations of subjects with and without caries. After application of these eligibility criteria, the selected articles were qualified by assessing their methodological quality. Initially, 338 articles were identified from the electronic databases after exclusion of duplicates. Exclusion criteria eliminated 322 articles, and 16 remained for evaluation. Eleven articles found a consistent association between salivary protein polymorphisms and risk of dental caries, for proteins related to antimicrobial activity (beta defensin 1 and lysozyme-like protein), pH control (carbonic anhydrase VI), and bacterial colonization/adhesion (lactotransferrin, mucin, and proline-rich protein Db). This systematic review demonstrated an association between genetic polymorphisms and risk of dental caries for most of the salivary proteins.

    The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries ( p = 0.329; OR = 2.2, 95% CI: 0.35-13.72) or dental erosion ( p = 0.590; OR = 2.33; 95% CI: 0.56-9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition ( p = 0.031; OR = 5.1; 95% CI: 1.61-23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

    To determine the feasibility of water fluoridation to prevent caries in Kunming by investigating the epidemiological status of dental caries and dental fluorosis of children, and to provide the longitudinal reference data for the long-term epidemiology survey of dental caries and dental fluorosis in Kunming city. Through stratified cluster sampling method, 212 5-year-old children and 1149 12-year-old children were recruited in the survey. Dental caries condition of each child was clinically examined, dental fluorosis was examined in 12-year-old group. The prevalence of dental caries of primary teeth in 5-year-old group was 73.6%, mean value was 4.47 +/- 4.39. The values of permanent teeth in 12-year-old group were 53.5% and 1.42 +/- 1.83. The prevalence of dental fluorosis in 12-year-old group was 4.1% and the average community fluorosis index was 0.03. Based on the high prevalence of dental caries and the low prevalence of dental fluorosis, it is suggested that using water fluoridation to prevent caries is feasible and necessary in Kunming city.

    Molar incisor hypomineralization is a developmental defect of dental enamel associated with rapid caries progression. In order to discover whether molar incisor hypomineralization predisposes to dental caries, a cross-sectional cohort study was conducted in a sample of 414 children aged between eight and nine years. It was found that 24.2% of the children presented molar incisor hypomineralization. Of these, 72% had a mild form and 28% a severe form. Caries prevalence was greater among the ch...

    Scarce information exists on the clinical features of dental caries in the Imperial Roman population and no structural data on caries lesions from this period have so far been published. We report on the findings of 86 teeth (50-100 AD) found during archaeological excavations of the temple of Castor and Pollux in the Forum Romanum. We found that nearly all teeth had large carious cavities extending into the pulp. The distribution and size of the caries lesions were similar to those found in contemporary adult populations in Africa and China living without access to dental care. Most lesions had a hypermineralized zone in the dentin at the advancing front of the carious cavities as revealed by micro-computed tomography. This biological dentin reaction combined with the morphology of the cavities might indicate that some temporary topical pain relief and intervention treatment slowed down the rate of lesion progression. This is indirectly supported by examination of cavities of similar size and depth from a contemporary population without access to dental health care. In contrast to the lesions in the Roman teeth, these lesions did not exhibit a hypermineralized dentin reaction. We investigated whether the Pb isotopic composition of enamel and/or dentin of a single tooth matched that of a sample of an ancient Forum water lead pipe. The Pb isotopic composition of the tooth did not match that of the tube, suggesting that the subjects were exposed to different Pb sources during their lifetime other than the lead tubes.

    2005-05-01

    As a prelude to development of broader-spectrum vaccines for dental caries, we explored the immune potential of constructs combining epitopes from mutans streptococcal glucosyltransferases (GTF) and glucan binding protein B (GbpB). Two diepitopic peptide constructs were synthesized in a multiple antigenic peptide (MAP) format. Both constructs contained SYI, a 20-mer GbpB peptide that included a sequence having major histocompatibility complex class II binding characteristics. One diepitopic construct (SYI-CAT) also contained a 22-mer sequence from the catalytic domain of GTF. Another diepitopic construct (SYI-GLU) contained a 22-mer sequence from the glucan binding domain of GTF. To assess the ability of each construct to induce antibody reactive with GbpB and GTF native proteins, rats were injected subcutaneously with SYI-CAT, SYI-GLU, or the constituent monoepitopic constructs. Only the SYI-CAT construct induced significant levels of serum immunoglobulin G (IgG) and IgA antibody to both pathogenesis-associated proteins. Also, immunization with SYI-CAT significantly (P dental caries after immunization with SYI-CAT, SYI, or CAT MAP constructs, followed by infection with Streptococcus mutans strain SJr. Dental caries were lower in each peptide-immunized group than in the sham-injected group. The level of protection after SYI-CAT immunization was similar to that after immunization with constituent MAP constructs. In another experiment, rats were infected with Streptococcus sobrinus strain 6715 under an identical protocol. Significant protection was observed on buccal surfaces in both SYI-CAT and CAT construct-immunized, but not in the SYI construct-immunized, groups. Thus, addition of the GbpB-derived SYI peptide to the GTF-derived CAT peptide construct not only enhanced the immunological response to CAT and GTF epitopes, but also extended the protective effect of the construct to include both S. mutans and S. sobrinus.

  10. The scientific and public-health imperative for a vaccine against dental caries.

    2006-07-01

    Dental caries is caused by one of the most ubiquitous bacterial infections of humans. In many countries such as Brazil and China, this disease is reaching epidemic proportions, and it is clear that a more effective public-health measure to combat dental caries is needed, because disadvantaged children are the most severely affected. One of the main groups of oral microorganisms, the mutans streptococci, has been associated with the aetiology of dental caries, and preclinical studies of immunological interventions have shown the feasibility of interfering with this disease. Moreover, clinical trials have indicated that a mucosal immune response to a crucial antigen(s) of mutans streptococci can influence the pathogenesis of dental caries. Evidence that this antigen(s) is appropriate for use in a vaccine against dental caries, as well as evidence for an appropriate target population of individuals and a logical time of administration, has now emerged.

    Dental caries affects ≤80% of the world’s population with almost a quarter of US adults having untreated caries. Dental caries is costly to health care and negatively affects well-being. Dietary free sugars are the most important risk factor for dental caries. The WHO has issued guidelines that recommend intake of free sugars should provide ≤10% of energy intake and suggest further reductions to caries risk, which showed evidence of moderate quality from cohort studies that limiting free sugars to ≤10% of energy reduced, but did not eliminate, dental caries. Even low levels of dental caries in children are of concern because caries is a lifelong progressive and cumulative disease. The systematic review therefore explored if there were further benefits to dental health if the intake of free sugars was limited to caries when free sugar intake was 5% but ≤10% of energy. The WHO recommendations are intended for use by policy makers as a benchmark when assessing intake of sugars by populations and as a driving force for policy change. Multiple strategies encompassing both upstream and downstream preventive approaches are now required to translate the recommendations into policy and practice. PMID:26773022

    Dental caries among preschool children remains a significant dental public health problem. In Ireland, there are no national data available regarding dental caries levels in preschool children. Furthermore, the number of young children with disabilities and their dental caries levels remains unknown. The aim of the present study was to measure the dental caries levels in a sample of preschool children with disabilities. A team of trained and calibrated dentists examined a sample of all 0- to 6-year old preschool children with disabilities in two health service administrative areas under standardized conditions. Dental caries was recorded using WHO criteria. Of a total of 422 participants, 337 datasets were included in the study. Of these 337 examined children, approximately 75.1% had a cognitive disability and 12.9% had a noncognitive disability. In 12% of the children, a diagnosis had not yet been established. Dental caries at dentin level was detected from the age of 4 years. The overall mean decayed/missing/ filled teeth (dmft) was 0.49 (SD, 1.39). The analysis of mean dmft levels in children with positive (dmft > 0) scores revealed a mean dmft of 1.14. The evidence from this study demonstrated that dental caries levels in preschool children with disabilities in Ireland are low when compared with the general population. Furthermore, children aged 3 years or younger exhibited no dental caries at dentin level and therefore were not affected by early childhood caries. An adjustment of current oral health prevention practice may lead to a further reduction in dental caries levels in this section of the child population.

    Streptococcus mutans (S. mutans) is the prime pathogen of dental caries. There are few reports that studied the relationship between S. mutans, bacteria and dental caries in permanent teeth when compared to those in primary teeth. This study aimed to detect S. mutans and bacteria of dental caries and non-caries groups in permanent teeth from a north China population by real-time polymerase chain reaction (PCR) and compare the relationship between the number of these bacteria and the prevalence of dental caries in permanent teeth. Human saliva samples were collected from 142 subjects with permanent teeth. According to their dental tooth (DT), 142 subjects were divided into a dental caries group (DT ≥ 1) and a non-caries group (DT = 0). With specific primers for S. mutans and 16S rRNA, the total number of S. mutans and total bacteria of 142 saliva samples were detected by real-time PCR and statistically analyzed. There was no significant difference between the detection rates of S. mutans (P = 0.118) and medians of S. mutans (P = 0.115). The ratio of S. mutans to total bacteria in people with dental caries was significantly higher than in those without caries (P dental caries was significantly lower than in those without caries (P caries in the permanent teeth of several individuals from a north China population. The ratios of S. mutans to total bacteria in saliva detected by real-time PCR with Sm479F/R and 16S RNA primers were closely associated with the prevalence of dental caries in the same population. These assays may be useful for the assessment of an individual's risk of dental caries.

    The nation's eating habits are undergoing major transformation, with a swing away from traditional meals to a huge increase in snack consumption, but very little is known of the nutritional and dental implications of this change. The research project reported here evaluated a range of snack foods in caries-active laboratory animals, comparing them, as dietary ingredients, with noncariogenic and cariogenic (sugar) diets. The findings showed the very low cariogenicity of salted peanuts, followed by ready-salted and salt and vinegar crisps, extruded maize, mixed-starch and prefabricated/fried potato products, and cheese-filled puffs. Other varieties of crisps (cheese and onion and special shapes) proved to be more cariogenic, not far short of semi-sweet biscuits in some cases. It is concluded that the severity of the processing undergone by the snack foods and the nature of the flavouring agents with which they are coated can influence their dental properties.

    Research on the association between dental caries and body mass index (BMI) in children has shown contradictory results; thus we aimed to examine the association between dental caries and the full range of BMI classes among children. We comprehensively searched PubMed, Embase, and the Cochrane Library for studies published prior to March 2017. Articles comparing dental caries among the full range of BMI classes for children below 18 years of both genders were included. Fourteen studies were eligible for this study. Basic information - i.e., first author, published year, study design, country, sample size, age, type of dental caries index and BMI, main results and conclusions, and means and standard deviations of the dental caries indexes used - was pooled. The weighted mean differences and corresponding 95% confidence intervals for dental caries between children with abnormal weight and those with normal weight were analyzed. Generally, no significant differences in caries were found between any abnormal-weight group and the normal-weight group for both primary and permanent teeth. Sensitivity analyses showed that the obese group had more caries than the normal-weight group in their primary teeth. Significantly more caries was found among the overweight and obese children in both primary and permanent teeth in high-income countries, but not in low- and middle-income countries. We recommend that further studies use suitable sample sizes, unify the criteria for BMI categorization and the dental caries index, and investigate the confounding factors that might influence dental caries and BMI. © 2018 S.

    Full Text Available Background: Dental caries is the predominant cause of tooth loss in children and young adults. Mutans streptococci are the principal etiological agents of dental caries, of which Streptococcus mutans (SM and Streptococcus sobrinus are most important in terms of human caries. Genetic factors also contribute to dental caries of which dermatoglyphics is one. Aim: The aim of the study was to explore the unique relationship between genetic component (dermatoglyphics and dental components (dental caries, salivary pH, SM level and to identify children at particular risk of dental decay. Settings and Design: One hundred children, 6–12 years of age, were selected and divided into two groups: Group 1 (children with dental caries, subject group and Group 2 (children without dental caries, control group. Methods: Dermatoglyphic patterns were recorded using a digital scanner (CanoScan LiDE, and dental caries status was recorded with “decayed-extracted-filled teeth” index for primary teeth and “decayed-missing-filled teeth” index for permanent teeth. Salivary pH was determined using pH meter strips. SM level was estimated by microbial culture of collected saliva samples. Statistical Analysis: Mann–Whitney test, Wilcoxon test, and Z-test were applied. Results and Conclusion: (1 Subject group had a decreased frequency of loops, whereas control group had increased frequency of loop pattern on palmer digits (P < 0.001. (2 Subject group had a low salivary pH toward normal and control group had high salivary pH values toward normal (P < 0.001. (3 Subject group had high SM level as compared to control group (P < 0.001. Therefore, there exists a relationship between genetic component (dermatoglyphics and dental component (dental caries, salivary pH, and SM level.

    There are no prospective studies investigating the effects of sugar-related feeding practices on changes in dental caries from early childhood to young adulthood. The aim of this study was to assess whether sugar-related feeding practices affect dental caries between the ages of 6 and 18 y. This birth cohort study was initiated in 1993 in Pelotas, Brazil. There were 3 dental clinical assessments; at ages 6 y (n = 359), 12 y (n = 339), and 18 y (n = 307). Sugar-related feeding practices were assessed at ages 4, 15, and 18 y. Covariates included sex and life course variables, such as family income, breast-feeding, mother's education, regularity of dental visit, and child's toothbrushing habits. Group-based trajectory analysis was performed to characterize trajectories of time-varying independent variables that had at least 3 time points. We fitted a generalized linear mixed model assuming negative binomial distribution with log link function on 3-time repeated dental caries assessments. One in 5 participants was classified as "high" sugar consumers, and nearly 40% were "upward consumers." "Low consumers" accounted for >40% of the sample. High and upward sugar consumers had higher dental caries prevalence and mean DMFT in all cohort waves when compared with low sugar consumers. Caries occurred at a relatively constant rate over the period of study, but in all sugar consumption groups, the increment of dental caries was slightly higher between ages 6 and 12 y than between 12 and 18 y. Adjusted analysis showed that dental caries increment ratio between ages 6 and 18 y was 20% and 66% higher in upward and high sugar consumer groups as compared with low consumers. The higher the sugar consumption along the life course, the higher the dental caries increment. Even the low level of sugar consumption was related to dental caries, despite the use of fluoride. © International & American Associations for Dental Research 2016.

    Few studies have been conducted to investigate the effects, if any, of specific medication used to manage the symptoms of attention deficit/hyperactivity disorder (ADHD) as a risk factor for dental caries. A reported side-effect of the medication is a reduction in saliva. Healthy saliva has been shown to play many important functions in the prevention of dental caries. The focus of this review is to determine if any evidence exists to confirm that stimulant medication used to treat the symptoms of ADHD in children increases the risk of dental caries by virtue of its effect on the reduction of salivary flow. A MEDLINE search was conducted for relevant studies. Search terms used were dental caries, attention deficit/hyperactivity disorder, ADHD, pharmacologic treatment of ADHD, stimulant medication, xerostomia, dry-mouth and saliva flow. Publication dates ranged from 2002 to 2012. Although dental caries prevalence has been found to be higher in children with ADHD, decreased salivary flow as a side-effect of pharmacological treatment does not appear to be responsible. Dental caries is a multi-factorial disease process. The most effective method of reducing dental caries in ADHD children is more frequent recare visits focusing on home plaque removal practices along with dietary counseling to reduce the consumption of cariogenic foods and drinks. This can only be accomplished with inclusion of the parent/guardian in the process. Copyright © 2014 The American Dental Hygienists’ Association.

    The aim of this study was to determine the contributions of sealant and water fluoridation to the time trends in dental caries from 2003 to 2010. Data were from three waves of the Korean National Oral Health Surveys between 2003 and 2010, including a total of 23 059 children (11 889 boys and 11 170 girls) aged 8, 10, and 12 years. The impacts of sealant and water fluoridation on dental caries were obtained by logistic regression for each age group of children. The contributions of sealant and water fluoridation to the time trends in the prevalence of dental caries were examined by a series of logistic regression models, and changes in the adjusted odds ratios for each survey year were also calculated. Over the past 7 years, the prevalence of dental caries decreased dramatically. Although sealant had a significant impact on dental caries in each survey year, remarkable decreases in dental caries from 2003 to 2010 were not explained by the secular changes in the dental sealant or water fluoridation factor. We observed important population declines in dental caries in Korea in children aged 8-12 years; however, the likely causes for these secular trends remain to be determined. © 2015 John Wiley & Sons A/S.

    Full Text Available The aim of this review is to give an overview of 55 years experience of milk fluoridation and draw conclusions about the applicability of the method. Fluoridated milk was first investigated in the early 1950s, almost simultaneously in Switzerland, the USA and Japan. Stimulated by the favourable results obtained from these early studies, the establishment of The Borrow Dental Milk Foundation (subsequently The Borrow Foundation in England gave an excellent opportunity for further research, both clinical and non-clinical, and a productive collaboration with the World Health Organization which began in the early 1980s. Numerous peer-reviewed publications in international journals showed clearly the bioavailability of fluoride in various types of milk. Clinical trials were initiated in the 1980s – some of these can be classed as randomised controlled trials, while most of the clinical studies were community preventive programmes. Conclusion. These evaluations showed clearly that the optimal daily intake of fluoride in milk is effective in preventing dental caries. The amount of fluoride added to milk depends on background fluoride exposure and age of the children: commonly in the range 0.5 to 1.0 mg per day. An advantage of the method is that a precise amount of fluoride can be delivered under controlled conditions. The cost of milk fluoridation programmes is low, about € 2 to 3 per child per year. Fluoridation of milk can be recommended as a caries preventive measure where the fluoride concentration in drinking water is suboptimal, caries experience in children is significant, and there is an existing school milk programme.

    To evaluate the inequality in dental caries distribution according to different thresholds assessed using the International Caries Detection and Assessment System (ICDAS) and to investigate the associations of socioeconomic factors with caries lesions at both noncavitated and cavitated thresholds. Study subjects were recruited in Santa Maria, Brazil, during the National Day of Children's Vaccination, and 639 children aged 12-59 months were included. Fifteen calibrated examiners performed the examinations using ICDAS criteria. Inequality in dental caries distribution was measured using the Gini coefficient, and the Significant Caries Index was calculated for several thresholds of ICDAS. Poisson regression analysis was used to assess the associations of socioeconomic factors with the highest caries scores. The inequality in the distribution of dental caries was lower when precavitated caries were included; the Gini coefficient decreased from 0.77 to 0.60 when noncavitated caries lesions were included in the analyses. Moreover, the inequalities were higher in the younger than in the older children for all thresholds. Socioeconomic factors were significantly (P < 0.001) associated with caries when an ICDAS score of 3 was considered as the cut-off point. Children whose mothers did not complete primary education (P < 0.001) and those with low household income (P < 0.001) were more likely to have increased dental caries. Caries lesions were more equally distributed when noncavitated lesions were included in the dental survey. Socioeconomic factors are found to be associated with the inequalities in caries distribution in this age group. © 2013 American Association of Public Health Dentistry.

    To ensure the oral health of a population, clinicians must deliver appropriate dental services, and local communities need to have access to dental care facilities. However, establishment of this infrastructure must be based on reliable information regarding disease prevalence and severity in the target population. The aims of this study were to measure the incidence of dental caries in school children aged 12-14 throughout Qatar, including the influence of socio-demographic factors. A cross-sectional study was conducted in Qatar from October 2011 to March 2012. A total of 2113 children aged 12-14 were randomly selected from 16 schools located in different geographic areas. Three calibrated examiners using World Health Organization (WHO) criteria to diagnose dental caries performed the clinical examinations. Data analyses were subsequently conducted. The mean decayed, missing, and filled teeth index values were respectively 4.62 (±3.2), 4.79 (±3.5), and 5.5 (±3.7), for 12, 13, and 14 year-old subjects. Caries prevalence was 85%. The mandibular incisors and canines were least affected by dental caries, while maxillary and mandibular molars exhibited the highest incidence of dental caries. Dental caries were affected by socio-demographic factors; significant differences were detected between female and male children, where more female children showed dental caries than male children. In addition, children residing in semi-urban areas showed more dental caries than in urban areas. Results indicated that dental caries prevalence among school children in Qatar has reached critical levels, and is influenced by socio-demographic factors. The mean decayed, missing, and filled teeth values obtained in this study were the second highest detected in the Eastern Mediterranean region.

    The etiology of dental caries is generally agreed to be a complex problem with many indirect factors that may obscure the direct cause or causes. There is substantial evidence that heredity plays an important role in this disease. Dermatoglyphics is a study that can be used to indicate congenital abnormalities. This study sought to determine a correlation between the prevalence of dental caries and dermatoglyphic fingerprint patterns, and thus assess the reliability of such patterns for identifying a susceptibility to dental caries. The results showed that the association between people with dental caries and whorls in their fingerprints was 60.4% . The association between people without caries who had loops in their fingerprints was 55.7%. These associations had a statistical significance of P < 0.001.

    Full Text Available Objectives: To investigate social and dental maternal characteristics related to the child’s caries experience and to verify the social representation of mothers with regard to the oral health-illness process. Methods: The sample consisted of 272 pairs of mothers and children who attending public institutions of early childhood education in Ponta Grossa city. The information of interest was collected through a structured, oral clinical examination and semi-structured interview. The test used for statistical analysis was a chi-square for independence. Results: The results confirmed the association between the mothers’ need for treatment and the children’s dental caries experience as well as their relationship with socio-economic variables. Education, income, number of children and frequency of visits to the dentist were the variables that showed statistical significance. Conclusion: Unfavorable maternal social inclusion, the number of children the mother has, their need for dental treatment and their frequency of visits to the dentist were associated with the children’s dental caries experience. Moreover, it appears that the mother’s social representations was an important tool for health information, and should be considered in the formulation of public policies.

    The purpose of this study was to assess Maryland dental hygienists' knowledge, practices and opinions regarding dental caries prevention and early detection. A 30 item survey was mailed to 1,258 Maryland dental hygienists. Two follow-up mailings and email reminders were sent. The response rate was 43% (n=540). Nearly all respondents were female (98%), and 58% practiced in solo settings. Knowledge and certainty of knowledge were moderate: sealants are needed regardless of topical fluoride use (55% certain, 40% less certain), newly erupted permanent molars are the best candidates for sealants (54%, 36%) and professionally applied fluorides are desirable in areas without fluoridated water (55%, 36%). Fewer were certain that incipient lesions can be remineralized before cavitation (23%, 69%), and dilute, frequently administered fluorides are more effective in caries prevention than concentrated, less frequently administered fluorides (6%, 24%). Opinions regarding effectiveness of protocols for 2 age groups from 6 months to 6 years, the challenges of early childhood caries (ECC), prevention practices regarding sealant and topical fluoride applications varied widely. Eighty-nine percent reported routinely assessing dental caries risk factors of child patients and 90% were interested in continuing education courses. There were no significant differences between different types of practice settings, year of graduation, race/ethnicity or gender. Knowledge of recommended guidelines for fluoride and sealant application support clinical decision-making and self-care counseling. Misinformation and lack of understanding of current research and recommendations identify a need for educational interventions in undergraduate dental hygiene programs and through continuing education for practicing hygienists.

    Full Text Available Streptococcus mutans (S. mutans are regarded as the main initiator microorganism of caries, with Lactobacilli participating on caries progression, due to its carcinogenic capacity. The purpose of this study was to examine the number of S. mutans and Lactobacillus sp in children with in children’s saliva with dental caries and free caries. Twenty children attending the Paediatric Dental Clinic in Airlangga University participated in our study. Their age ranged from 1–14 years old. Subject was divided into two groups, which were study group consisting of 10 children with 3–5 dmft/DMFT and control group with 10 caries free children. Subjects were examined and their caries number was recorded using WHO index. Stimulated saliva was collected from each subject for bacterial assessment. Colony counting of S. mutans and Lactobacillus sp count in each saliva sample group were done. The study showed that subject with 3–5 dmft/DMFT had higher number of S. mutans and Lactobacillus sp than caries free.

    The association between trauma and caries is still controversial in the literature. The aim of this study was to evaluate the possible association between caries and dental trauma through a systematic review with meta-analysis. A systematic literature search was performed in PubMed, Lilacs, BBO, Scopus, Web of Science, Cochrane Library, and Open Grey databases. The MeSH terms used were 'Tooth injuries', 'Tooth fractures', 'Tooth avulsion', 'Tooth movement'; 'Dental caries'; 'DMF index'; and 'Tooth demineralization'. MeSH synonyms, related terms, and free terms were included. The inclusion criteria comprised clinical investigations of subjects with and without caries that had suffered dental trauma. Quality assessment and bias control were carried out. Meta-analysis was performed using the comprehensive meta-analysis software (version 3.2). Heterogeneity was assessed using the I 2 index, and the odds ratio was also calculated (P dental trauma and dental caries in permanent teeth [OR: 1.490, 95%, CI: 1.209-1.835]. However, for children with primary teeth, the results showed a negative association (P = 0.006) between dental trauma and caries [OR: 0.706, 95%, CI: 0.550-0.906]. The results demonstrated positive and negative association between the presence of caries and dental trauma in permanent and primary teeth, respectively. © 2016 John Wiley & Sons A/S.

    Obesity and dental caries have become increasingly prevalent challenges to public health. Research results into the relationship between obesity and dental caries in children have been mixed and inconclusive. The aim of this review and meta-analysis was to provide evidence to quantify the relationship between obesity and dental caries in children using a systematic approach. A systematic search for papers between 1980 and 2010 addressing childhood obesity and dental caries was conducted and a random effects model meta-analysis applied. Fourteen papers met the selection criteria. Overall, a significant relationship between childhood obesity and dental caries (effect size = 0.104, P = 0.049) was found. When analysed by dentition type (primary versus permanent), there was a nonsignificant association of obesity and dental caries in permanent and primary dentitions, yet on accounting only for standardized definitions for assessment of child obesity using body mass index, a strong significant relationship was evident in children with permanent dentitions. Moderating for study country of origin (newly 'industrialized' versus industrialized) showed a significant relationship between obesity and dental caries in children from industrialized but not newly industrialized countries. Cofactors such as age and socioeconomic class were significant moderators. Future analysis should investigate these confounding variables, helping shape the future of obesity management programmes and oral health interventions, through determining common risk factors. © 2012 John Wiley & Sons A/S.

    The aim of the study was to evaluate the prevalence and severity of dental caries among 18-year-old Lithuanian adolescents and to disclose possible differences in the prevalence and severity of dental caries related to gender, urbanization, and different county. A total of 1063 18-year-old adolescents attending school, 427 boys and 636 girls from 10 Lithuanian counties including urban and rural areas, were included in the cross-sectional study on dental caries. The method of multistage cluster sampling was used. The dental examination was performed according to the methodology of oral status evaluation recommendations by the World Health Organization (WHO). The prevalence of dental caries, DMFT score, Significant Caries Index, and dental care index were determined. The overall prevalence of dental caries among 18-year-old Lithuanian adolescents was 78.3%. The study population had a mean DMFT score of 2.93 [SD, 2.81]. Considering the gender, a higher DMFT score was observed among girls than boys (3.03 [SD, 2.88] versus 2.73 [SD, 2.71]) and in rural than urban areas (3.02 [SD, 2.98] versus 2.89 [SD, 2.73]). The Significant Caries Index and the dental care index among 18-year-old adolescents were 6.14 and 62.3%, respectively. This study showed a relatively high prevalence of dental caries. The existing differences of caries experience between the urban and the rural areas as well as between the counties could be influenced by the socioeconomic differences in the country.

    This ross-sectional study involving 127 male prisoners evaluates the use of dental services and dental caries among Brazilian inmates. Data were collected by interview and clinical examination. Sociodemographic and sentencing information as well as use of dental services, self-reported dental morbidity, self-perception, and oral health impacts were investigated. The mean DMFT index value was 19.72. Of the components, the decayed component showed the highest mean value (11.06 ± 5.37). Statistically significant association was found between DMFTs with values from 22 to 32 and oral health satisfaction (p = 0.002), difficulty speaking (p = 0.024), shame of talking (p = 0.004) and smiling (p dental services, 80% had their last dental appointment less than one year ago, with most visits occurring in prison (80%), with restorative treatment (32%), followed by dental pain (26.4%), being the main reasons for such appointments. Most prisoners used dental services provided by the prison. Although restorative treatment has been the main reason for the use of dental services, "decayed" and "missing" components contributed to the high mean DMFT index.

    Full Text Available School remains an important setting offering an effective and efficient ways to reach over to children and through them, families and community members.(1 Dental caries is very common disease in childhood, interfering with food intake affecting physical development in the form of malnutrition, child’s school attendance and academic performance. Tooth decay or cavities caused by dental caries is an infectious disease and is diet and oral hygiene dependent. If left untreated result in toothache, permanent cavitations and children with active disease become adult with tooth decay. Also poor dentition and malocclusion decreases the masticatory performance effecting oral health and quality of life. Fortunately dental caries is both preventable and treatable with effective home care and regular access to preventive dental services. The present study was carried out in the rural area of Konkan region to assess the awareness regarding oral hygiene, prevalence of dental caries, to assess the masticatory performance.

    To determine whether children advised by a pediatrician to take sports drinks consume them more frequently than do other children and whether these children have an increased risk of dental caries. The subjects were 522 mother/child pairs who attended a dental checkup for 3-year-olds at one of ten community health centers in Nagasaki, Japan. Pearson's chi-square test was used to compare the prevalence of children with or without dental caries according to child-related variables. Multiple logistic regression was performed to assess the relationship between the presence of dental caries and child-related variables taken from a dental checkup and a questionnaire. A high frequency of sports drink consumption was strongly associated with dental caries in children. The highest proportion of mothers answered that they were advised by a pediatrician to give sports drinks to their children. However, these children consumed sports drinks significantly less frequently than did children who did so for reasons other than pediatrician recommendations. In addition, these children were significantly less likely to have dental caries than were children who consumed sports drinks for otherreasons. Pediatrician-recommended consumption of sports drinks does not lead to more frequent consumption of these beverages or to dental caries in 3-year-old children.

    The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. A community-based, cross-sectional study among 2376 elderly subjects (age: 65-74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Ppopulation in urban areas (OR 1.713; 95% CI 1.337-2.195), smoking (OR 1.779; 95% CI 1.384-2.288), and individuals without dental insurance (OR 2.050; 95% CI 1.120-3.754) with dental caries. The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries.

    Few studies have examined dental caries experience in Aboriginal adults. The objectives of this study were to describe the dental caries experience of some Aboriginal Australian adults residing in the Northern Territory, and to determine associations with dental caries experience. A convenience sample of Aboriginal adults from Australia's Northern Territory was dentally examined. Self-reported oral health information was collected through a questionnaire. Data were available for 312 participants. The per cent of untreated decayed teeth (per cent DT >0) was 77.9 (95% CI 73.0 to 82.1), the mean DT was 3.0 (95% CI 2.6 to 3.4), the prevalence of any caries experience (the per cent DMFT >0) was 95.5 (95% CI 92.6 to 97.3) and the mean DMFT was 9.7 (95% CI 8.9 to 10.5). In multivariable analyses, unemployment and not brushing teeth the previous day were associated with the per cent DT >0. Problem-based dental attendance was associated with both the mean DT and the per cent DMFT >0. Older age, residing in the capital city, being non-incarcerated, last visiting a dentist caries experience among this convenience sample of Aboriginal Australian adults was very high. Most factors associated with dental caries were social determinants or dental service access-related. © 2015 Australian Dental Association.

    To determine the dental caries experience and treatment needs among 5-year-olds in Albania. This cross sectional study was conducted in 2015 by using a cluster sampling technique. The dmft was used to assess dental caries experience and caries prevalence as percentages of children with dmf⟩0. Caries treatment needs were assessed with dt/dmft x 100, missing teeth with mt/dmft x 100 and ft /dmft x 100 as the Care Index. 2,039 five-year-olds, from 17 districts of Albania were selected . Children's residency was divided into 3 main regions (South, West, Central and North). WHO 2013 diagnostic criteria were used and dental caries was recorded at cavity level d3. The mean age was 5.4 (SD 0.5) years. The caries prevalence (dmf⟩0) was 84.1%. The prevalence of children without cavitated lesions (d=0) was 20.1%. The mean dmft index was 4.41 (SD 3.83). The caries treatment needs were 84% (SD 26%). The Albanian 5-year-olds assessed in this survey had a high dental caries experience and untreated cavities in the primary dentition. The national health authorities should introduce preventive programs and improved dental care access for this age group. Copyright© 2017 Dennis Barber Ltd

    In this paper, a one-dimensional (1D) thermal-wave model coupled diffuse-photon-density-wave for three-layer dental tissues using modulated laser stimulation was employed to illustrate the relationship between dental caries characteristic (i.e. caries layer thickness, optical absorption coefficient and optical scattering coefficient) and photothermal radiometry (PTR) signal. Experimental investigation of artificial caries was carried out using PTR scanning imaging. The PTR amplitude and phase delay were increased with dental demineralized treatment. The local caries characteristic parameters were obtained by the best-fitting method based on the 1D thermal-wave model. The PTR scanning imaging measurements illustrated that the optical absorption coefficient and scattering coefficient of caries region were much higher than those of the healthy enamel area. The demineralization thickness of caries region was measured by PTR scanning imaging and its average value shows in good agreement with the digital microscope. Experimental results show that PTR scanning imaging has the merits of high contrast for local inhomogeneity of dental caries; furthermore, this method is an allowance to provide a flexibility for non-contact quantitative evaluation of dental caries.

    To explore the possible association between weight class and prevalence of caries among children born 2005-2007, living in Nuuk, Greenland, at time of school entry. A cross-sectional register study based on data from electronic medical records(EMR) and oral health data from public health and dental care facilities. Data from routine examinations of children at time of primary school entry, including height and weight, were obtained from the EMRs. Dental charts recording oral health and caries were collected from public dental healthcare service. The prevalence of caries was calculated as the proportion of included children with dft score (decayed and/or filled non-permanent teeth) ≥1. 55%(373/681) had relevant data recorded in EMRs and dental charts, and could be included in the study. The prevalence of dental caries was 57.1%(213/373). The prevalence of caries increased with higher weight class,but no statistically significant trend was observed(p=0.063). Increasing prevalence of caries with increasing weight class was observed in this study. A linear trend could not be confirmed statistically. The high prevalence of caries and overweight indicate the need for continued focus on preventative initiatives and monitoring. A combined strategy targeting both caries and overweight may be considered.

    Full Text Available OBJECTIVES: Autism is a lifelong neurodevelopmental disorder. The aims of this study were to investigate whether children with autism have higher caries prevalence, higher periodontal problems, or more treatment needs than children of a control group of non-autistic patients, and to provide baseline data to enable comparison and future planning of dental services to autistic children. MATERIAL AND METHODS: 61 patients with autism aged 6-16 years (45 males and 16 females attending Dubai and Sharjah Autism Centers were selected for the study. The control group consisted of 61 non-autistic patients chosen from relatives or friends of autistic patients in an attempt to have matched age, sex and socioeconomic status. Each patient received a complete oral and periodontal examination, assessment of caries prevalence, and caries severity. Other conditions assessed were dental plaque, gingivitis, restorations and treatment needs. Chi-square and Fisher's exact test of significance were used to compare groups. RESULTS: The autism group had a male-to-female ratio of 2.8:1. Compared to controls, children with autism had significantly higher decayed, missing or filled teeth than unaffected patients and significantly needed more restorative dental treatment. The restorative index (RI and Met Need Index (MNI for the autistic children were 0.02 and 0.3, respectively. The majority of the autistic children either having poor 59.0% (36/61 or fair 37.8% (23/61 oral hygiene compared with healthy control subjects. Likewise, 97.0% (59/61 of the autistic children had gingivitis. CONCLUSIONS: Children with autism exhibited a higher caries prevalence, poor oral hygiene and extensive unmet needs for dental treatment than non-autistic healthy control group. Thus oral health program that emphasizes prevention should be considered of particular importance for children and young people with autism.

    Full Text Available Context Oral health status plays an essential role in human health. Recently, enhancement in oral health caries has been noted in both developed and developing countries. Dental caries is still very common among children. Screening and preventive interventions is necessary. The aim of this study was to review the diagnostic and preventive approaches for dental caries in children. Evidence Acquisition Searching PubMed, Medline, the Cochrane Library (for 5 recent years from 2011 - 2016, and reference lists for keywords and phrases such as “dental caries in children” and prevention and diagnosis, we included trials and controlled observational studies regarding the diagnosis and preventive techniques for dental caries in children. Results We found no study demonstrating the effects of screening by primary care providers on clinical outcomes. In a cohort study, pediatrician examination associated with a sensitivity of 0.76 was reported to identify dental caries in children. The results of the new randomized trials that were confirmed by previous studies showed that the efficacy of fluoride varnish is more than no varnish in reduction of dental caries from 18% to 59%. Some of the trials regarding xylitol had no results regarding the effects on dental caries. New observational studies have shown an association between early childhood fluoride use and enamel fluorosis. There is no evidence on the accuracy of prediction instruments in primary care settings. Conclusions We found no direct evidence that reveals that screening by primary care clinicians can decrease early childhood caries. Previous evidences reviewed by the United State Preventive Services Task Force demonstrated that oral fluoride supplementation is effective in decreasing caries incidences, and recent evidences supported the effectiveness of fluoride varnish in higher-risk children.

    To investigate the association between malocclusion/dentofacial anomalies and dental caries among adolescents. A cross-sectional study was conducted with 509 adolescents aged 11 to 14 years enrolled at public schools in the city of Osório in southern Brazil. Parents/caregivers answered a structured questionnaire on demographic and socioeconomic variables. A trained examiner recorded the presence of malocclusion (Dental Aesthetic Index [DAI]), traumatic dental injury, and dental caries. Data analysis involved the chi-square, Mann-Whitney, and Kruskal-Wallis tests. Poisson regression with robust variance was used for the multivariable analysis. A total of 44.8% of the adolescents had dental caries (mean DFMT  =  1.33 ± 1.84). The DAI index ranged from 15 to 77 (mean  =  29.0 ± 7.9); 43.6% of the sample had severe malocclusion and 11.6% had traumatic dental injury. The prevalence and severity of dental caries were significantly greater among adolescents with severe malocclusion. The multivariate analysis demonstrated that adolescents with severe or handicapping malocclusion had a 31% greater probability of having dental caries (prevalence ratio: 1.31; 95% CI: 1.02-1.67), independently of demographic, socioeconomic, or clinical aspects. The orthodontic characteristics associated with the occurrence and severity of caries were maxillary irregularity ≥3 mm (P  =  .021) and abnormal molar relationship (P  =  .021). Handicapping malocclusion, maxillary irregularity, and abnormal molar relationship were associated with the occurrence and severity of dental caries. The findings suggest that the prevention and treatment of these conditions can contribute to a reduction in dental caries among adolescents.

    The aim of the study is to assess the relationship between caries and dental fluorosis in Ethiopian children living in Rift Valley areas known for endemic fluorosis. A total of 306 children (12-15 years old), selected from areas with moderate (0.3-2.2 mg/l), or high (10-14 mg/l) fluoride concentration in the drinking water were interviewed and examined for caries and dental fluorosis. Scorings were recorded according to the DMF system, and the Thylstrup-Fejerskov (TF) Index. Prevalence of dental fluorosis (TF-score > or = 1) was 91.8% (moderate area) and 100% (high-fluoride area). The corresponding caries prevalence and mean DMFT in the areas were 45.3% versus 61.6%, and 1.2 versus 1.8, respectively. Age and severity of dental fluorosis were found to be independent predictors for DMFT > or = 1. When compared with 12-year olds with TF-scores 0-4, odds ratios were 3.0 (95% CI 1.6-5.7) and 2.0 (95% CI 1.2-3.2) if TF-scores were > or = 5 and age 13-15 years, respectively. A positive relationship between caries and fluorosis was observed across tooth types in both areas. The percentage of children with DMFT > or = 1 was highest in groups with TF-score > or = 5 in the second molar, followed by the first molar. The present findings indicate that the second molar is the tooth most severely affected by dental fluorosis and dental caries. Dental caries increased with increasing severity of dental fluorosis, both in moderate- and high-fluoride areas. Thus, a positive relationship between dental caries and dental fluorosis was observed across various tooth types, in both areas. Copyright Blackwell Munksgaard, 2004

    Full Text Available Dental care is consistently reported as one of the primary medical needs of children with disabilities (IDC. The aim of the present study was to explore the influence of oral health behaviors on the caries experience in children with intellectual disabilities in Guangzhou, China. A cross-sectional study was carried out in 477 intellectually disabled children, 12 to 17 years old, who were randomly selected from special educational schools in Guangzhou. A self-administered parental questionnaire was used to collect data on socio-demographic characteristics and oral health behavior variables, and 450 valid questionnaires were returned. Multiple regression analysis was used to examine the factors associated with dental caries. The average age of those in the sample was 14.6 years (SD = 1.3, 68.4% of whom were male, and the caries prevalence rate was 53.5% (DMFT = 1.5 ± 2.0. The factors significantly affecting the development of dental caries in IDC included gender, the presence or absence of cerebral palsy, and the frequency of dental visits and toothbrushing. In conclusion, the presence of cerebral palsy contributed to an increase risk of caries experience in intellectually disabled children, while toothbrushing more than twice a day and routine dental visits were caries-protective factors. Oral health promotion action may lead to a reduction in dental caries levels in IDC.

    Dental caries is the main problem oral health and it is not well established in the literature if the enamel defects are a risk factor for its development. Studies have reported a potential association between developmental defects enamel (DDE) and dental caries occurrence. We investigated the association between DDE and caries in permanent dentition of children and teenagers. A systematic review was carried out using four databases (Pubmed, Web of Science, Embase, and Science Direct), which were searched from their earliest records until December 31, 2014. Population-based studies assessing differences in dental caries experience according to the presence of enamel defects (and their types) were included. PRISMA guidelines for reporting systematic reviews were followed. Meta-analysis was performed to assess the pooled effect, and meta-regression was carried out to identify heterogeneity sources. From the 2558 initially identified papers, nine studies fulfilled all inclusion criteria after checking the titles, abstracts, references, and complete reading. Seven of them were included in the meta-analysis with random model. A positive association between enamel defects and dental caries was identified; meta-analysis showed that individuals with DDE had higher pooled odds of having dental caries experience [OR 2.21 (95% CI 1.3; 3.54)]. Meta-regression analysis demonstrated that adjustment for sociodemographic factors, countries' socioeconomic status, and bias (quality of studies) explained the high heterogeneity observed. A higher chance of dental caries should be expected among individuals with enamel defects. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available La caries dental es una enfermedad multifactorial que representa un problema de salud pública global y nacional. Se conocen los factores de riesgo individual, no así los asociados con su ocurrencia poblacional; no es claro por qué algunos países o regiones presentan mayor prevalencia que otros. Es necesario analizar los determinantes sociales de la salud (DSS asociados. El objetivo de este estudio fue explorar la asociación entre algunos determinantes poblacionales y la prevalencia de caries dental en la población infantil mexicana. Se realizó un estudio de casos de carácter ecológico cuyas unidades de observación fueron las 32 entidades federativas de la República mexicana.

    Full Text Available Background/Aim. It is considered that over 450 million people worldwide suffer from some form of mental disorder. Previous studies in other countries have shown that schizophrenia is among the most frequent. Oral health is significant for general health and should not be separated from mental health. Studies in other countries have shown an increased incidence of carious and extracted teeth, and less incidence of filled teeth in this group of psychiatric patients. The aim of this study was to establish condition of the existing teeth, to determine the prevalence of caries and to consider possible risk factors that contribute to the current oral health status of hospitalized patients with schizophrenia. Methods. The study comprised 190 patients with schizophrenia, hospitalized at the Clinic for Psychiatric Disorders “Dr. Laza Lazarević” in Belgrade, and 190 mentally healthy patients at the Clinic for Periodontology and Oral Medicine, Faculty of Dental Medicine in Belgrade. The decayed, missing, filled (DMF index, sociodemographic and economic characteristics were registered in both groups, as well as characteristics of the primary disease of hospitalized patients with schizophrenia. Results. The value of DMF index (representing the sum of carious, extracted and filled teeth, in the hospitalized patients with schizophrenia was 18.57 ± 7.07 and 12.47 ± 5.64 in the healthy group (p = 0.000. The structure of the DMF index in the study group showed that caries and extracted teeth dominated with 88.1%; in the control group, filled teeth dominated with 55.6%, which was a statistically significant difference for all the three observed variables. Conclusion. Hospitalized patients with schizophrenia had twice as many caries and extracted teeth, and five time less filled teeth than healthy people. The patient’s age and taking antiparkinsonics were established as predictors of the increased DMF index in hospitalized patients with schizophrenia.

    Full Text Available Background: Dental caries remains the most important dental health problem in developing countries. In India the prevalence of dental caries is reported to be about 50-60%. Most of the Indian studies have been carried out in school children and very few in adults. This study aimed to estimate the prevalence of dental caries in the adult population (aged 35-44 years and in the elderly (60 years and above in an urban resettlement colony in New Delhi. Methodology: A community-based cross-sectional study was carried out in Dakshinpuri, New Delhi, from January to February 2007. A local adaptation of the WHO questionnaire was used. Oral examination was done and dentition status was recorded by trained investigators and according to the standard procedures. Results: A total of 452 participants were enrolled in the study. The prevalence of dental caries in the 35-44 years age-group was 82.4% and it was 91.9% in those ≥60 years. The DMF index was 5.7 ± 4.7 in the 35-44 years age-group and 13.8 ± 9.6 in the ≥60 years age-group. Of the participants, 27.9% were currently using tobacco. A statistically significant association was found between tobacco consumption and dental caries ( P = 0.026. The awareness about good and bad dental practices was found to be low among the study participants. One-fifth of the individuals with dental problems relied on home remedies. Conclusion: The prevalence of dental caries among adults is high in this population. There is a need to generate awareness about oral health and the prevention of dental caries and to institute measures for the provision of dental care services at the primary level.

    Full Text Available New types of copolymers using monomers which form inorganic polymers network (glass-like and organic networks have been developed, known as ormocers. The aim of this work was to study how a particular dental filling material is degraded when subjected to a caries challenge by using low pH solutions. The supernadants were studied by HPLC to detect the presence of molecules from the resin, while the changes of the material surface were evaluated by contact angle. An organic modified ceromer (ormocer called Definite® (Degussa was tested. Samples were built following manufacturer's instructions. After pH cycles, solutions were injected in a HPLC. The contact angle was obtained using a goniometer after and before the cycles. HPLC results showed material degradation, only detected in acid solutions. Bis-GMA and TEGDMA were detected in Definite® residues. Means and S.D. of contact angle were (p < 0,05: baseline: 85.16° ± 3.90° and after pH cycles: 69.77° ± 7.12°. The authors concluded that an ormocer filling material degraded on a caries simulated environment.

    Topically applied fluoride gels have been widely used as a caries-preventive intervention in dental surgeries and school-based programmes for over three decades. This updates the Cochrane review of fluoride gels for preventing dental caries in children and adolescents that was first published in 2002. The primary objective is to determine the effectiveness and safety of fluoride gels in preventing dental caries in the child and adolescent population.The secondary objectives are to examine whether the effect of fluoride gels is influenced by the following: initial level of caries severity; background exposure to fluoride in water (or salt), toothpastes, or reported fluoride sources other than the study option(s); mode of use (self applied under supervision or operator-applied), and whether there is a differential effect between the tray and toothbrush methods of application; frequency of use (times per year) or fluoride concentration (ppm F). We searched the Cochrane Oral Health Group Trials Register (to 5 November 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2014, Issue 11), MEDLINE via OVID (1946 to 5 November 2014), EMBASE via OVID (1980 to 5 November 2014), CINAHL via EBSCO (1980 to 5 November 2014), LILACS and BBO via the BIREME Virtual Health Library (1980 to 5 November 2014), ProQuest Dissertations and Theses (1861 to 5 November 2014) and Web of Science Conference Proceedings (1945 to 5 November 2014). We undertook a search for ongoing trials on ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform on 5 November 2014. We placed no restrictions on language or date of publication in the search of the electronic databases. We also searched reference lists of articles and contacted selected authors and manufacturers.

    Photoacoustic method to detect hidden dental caries is proposed. It was found that high frequency ultrasonic waves are generated from hidden carious part when radiating laser light to occlusal surface of model tooth. By making a map of intensity of these high frequency components, photoacoustic images of hidden caries were successfully obtained. A photoacoustic imaging system using a bundle of hollow optical fiber was fabricated for using clinical application, and clear photoacoustic image of hidden caries was also obtained by this system.

    The high prevalence of dental caries in children worldwide is a major oral health problem which requires early intervention. Dental caries is mainly caused by the action of acids produced by bacteria in addition to many other factors. Recent genetic studies have reported that a number of genes are associated with the susceptibility to dental caries. The majority of these genes are associated with inflammation, increased susceptibility to infection, and dentine matrix formation. Using the TaqMan assay and direct DNA sequencing, the prevalence of 6 single-nucleotide polymorphisms (SNPs) in MMP9, MBL2, MMP2, and TIMP2 genes was determined in 102 children with caries and in 100 age-matched caries-free controls. Out of the 6 SNPs tested in the 4 selected genes, only rs11003125 in the MBL2 gene was shown to be associated with a high prevalence of caries in our cohort. In addition, haplotype analysis of the 6 SNPs tested revealed that certain haplotypes, namely GT of rs11003125G and rs7501477T and GT of rs7096206G and rs7501477T, were found to be associated with a high prevalence of dental caries in our cohort, while haplotype AG of rs17576A and rs7501477G was found to have a protective effect against dental caries. In conclusion, the data indicate that rs11003125 in the MBL2 gene was shown to be associated with a high prevalence of caries in our cohort, and 2 haplotypes are also involved in the increased susceptibility to dental caries. © 2016 S.

    Experience and awareness of adult females concerning dental caries is important in its prevention particularly in children because of their natural role as care givers. To determine the prevalence of dental caries and treatment needs in an adult female Nigerian population. In this cross-sectional study, adult females attending outreach programmes were examined for dental caries using the Decayed Missing and Filled Teeth caries index (DMFT). Socio-demographic variables were also recorded and statistical analysis done with SPSS software. A total of 430 females aged 16 to 59 years participated in the outreach programme out of which 109 (25.3%) had a DMFT score > 0. Mean DMFT was 0.7 ± 1.6. Fifty-five (12.8%) participants had decayed teeth, 78 (18.1 %) had missing teeth and 10(2.3%) had filled teeth. The treatment need was 34.3%, restorative index was 13.3% and significant caries index was 2.0. There were significant differences in caries experience based on age, marital status and educational qualifications of participants p caries among the study group was low but the treatment need was high. Younger females, singles and those with lower educational qualifications had a higher dental caries experience.

    1993-01-01

    Given the decline in dental caries incidence in preteens and young teenagers in the United States, a study of the incidence of dental caries in young adults (17-23 years) was conducted to provide a descriptive epidemiologic picture of this "new" natural history of dental caries in the late and post-teenage years. A retrospective study was performed analyzing the detailed dental records of the four-year college experience in the class of 1989, US Coast Guard Academy. Occlusal caries incidence, in the absence of associated proximal caries, was shown to be moderately common in molars (11.9%) and rare in premolars (0.8%). In contrast to previous studies' findings, demographic indicators, socioeconomic status indicators, and prior caries experience were poor predictors of occlusal caries incidence; targeting a universal sealant policy in this population therefore would be done best by tooth type rather than patient type. A preliminary cost-comparison model, projected over a 40-month period, suggests that the cost of initiating a universal molar sealant policy in this population would be 92 cents per year per student greater than the cost of restoring occlusal caries in the presence of sound proximal surfaces. This cost comparison suggests that it would be advantageous to initiate such a policy.

    Full Text Available Statement of Problem: Dental caries is one of the common diseases in the world. It is an infective disease which is caused by loss of minerals and destruction of dental tissues. One of the most effective ways to diagnose the interproximal caries is radiography. Bitewing radiography is the best way for caries diagnosis.Purpose: The aim of this study was to evaluate the prevalence of the interproximal caries in dental students of Islamic Azad University.Materials and Methods: This research was a cross sectional study that was conducted on 89 students of the Azad University consisting of 48 females and 41 males who were selected by random sampling. For each individual student left and right posterior bitewing radiographs were taken with a standard method (the interproximal spaces were between 6-7,5,6 and 4,5. Thus 12 interproximal spaces were examined in each individual. The most proximal cavitation surfaces were detected in the upper Jaw.Results: Results revealed that 6 individuals (6.7% were totally caries free and 83 individuals (93.3% showed interproxmal caries. Out of 1068 proximal spaces which had been studied 794 Spaces (73.4% were caries free and 274 surfaces (25.7% had caries.Conclusion: The high incidence of proximal caries and the possibility of missing them in the routine examinations make the bitewing radiographs an effective procedure for diagnosis.

    Full Text Available Early childhood caries affects 28% of children aged 2–6 in the US and is not decreasing. There is a well-recognized need to identify susceptible children at birth. Caries-free adults neutralize bacterial acids in dental biofilms better than adults with severe caries. Saliva contains acidic and basic proline-rich proteins (PRPs which attach to oral streptococci. The PRPs are encoded within a small region of chromosome 12. An acidic PRP allele (Db protects Caucasian children from caries but is more common in African Americans. Some basic PRP allelic phenotypes have a three-fold greater frequency in caries-free adults than in those with severe caries. Early childhood caries may associate with an absence of certain basic PRP alleles which bind oral streptococci, neutralize biofilm acids, and are in linkage disequilibrium with Db in Caucasians. The encoding of basic PRP alleles is updated and a new technology for genotyping them is described.

    Caries is a disease which on the basis of numerous epidemiological data it should be possible to control. The preventive interventions which have proved to have the greatest effect on the diffusion of this disease are essentially: fluoroprophylaxis, oral hygiene, food hygiene and periodic dental examination. The common denominator, which has the greatest effect on success, is a good level of health education of the populations affected by the programme, with specific reference to the teeth. The importance of the diet as a possible element predisposing to caries is an ascertained fact by now, and in fact it is well known that the greatest cariogenic effect is achieved after eating foods containing large quantities of fermentable sugars at irregular intervals throughout the day, especially in the form of products of high density and viscosity. The proposal to replace sugar with substitutive sweeteners such as: xilitol, sorbitol, licasin, talin, palatinit and, more recently, aspartame does not completely solve the problem; and apart from this the clearcut reduction of caries achieved in different European and non-European countries does not appear to be directly connected with a drop in sugar consumption, while more and more importance is ascribed to individual food choices. Oral hygiene procedures aim not only at the cleaning of teeth but also, to some extent, controlling the bacterial plaque. For this reason these are sometimes included among anticaries interventions; however opinions differ in this regard, with a clear prevalence of negative views. The question changes radically if we combine with mechanical procedures alone the use of fluoride-based toothpastes, which are recognised, in combination with other interventions, as playing a fundamental role in the rapid decline of caries in industralised countries. Toothpaste is considered as an excellent vehicle for the topical application of fluoride since it comes into contact with the teeth is slight

    Dental caries is a multifactorial condition, prevention of which requires comprehensive understanding of both contextual and compositional determinants and their population impact. To investigate contextual and compositional factors associated with the prevalence of dental caries in children and to estimate the population impact of those factors. Children in one Australian state were selected through stratified random sampling selection in 2010-2011. Oral epidemiological examinations provided individual-level outcomes: prevalence of dental caries in the primary (among 5- to 8-year-olds) and permanent dentitions (9- to 14-year-olds). Socioeconomic status, oral health behaviours and practices and dietary patterns were explanatory factors at the individual-level, school-level and area-level fluoridation status. Three-level multilevel multivariable models were sequentially specified for the prevalence of dental caries to estimate prevalence ratios (PR) associated with explanatory factors, adjusting for covariates and between- and within-group variances. Population attributable fraction (PAF) was estimated as the population impact of the statistically significant explanatory factors. Data from 2214 5- to 8-year-olds and 3186 9- to 14-year-olds from 207 schools in 16 areas were analysed. The prevalence of dental caries in the primary and the permanent dentitions was 47.1% (43.9-50.4) and 38.8% (36.1-41.6), respectively. The highest prevalence of dental caries was observed in the nonfluoridated areas. In bivariate associations, factors at three levels were associated with prevalence of dental caries. In the full models, children in the nonfluoridated areas had significantly higher prevalence of dental caries [PR for the primary: 1.29 (1.11-1.50); PR for the permanent 1.49 (1.01-2.21)] compared with children in fluoridated areas, controlling for other factors. PAF estimates indicated that lack of water fluoridation attributed to 21% and 31% of primary and permanent dental

    Full Text Available The aim of the present study was to investigate determinant factors associated with the presence of dental caries and lesion activity in preschool children. A population-based, cross-sectional study was carried out with 843 children of aged three to five years enrolled at public and private preschools in the city of Campina Grande, Brazil. A questionnaire addressing socio-demographic data and oral health care was self-administered by parents/caregivers. Three dentists previously calibrated examined the children for the diagnosis of dental caries and lesion activity using the International Caries Detection and Assessment System (ICDAS. Nutritional status was evaluated based on the body mass index. Logistic regression analysis for complex samples was performed (α = 5%. The prevalence of dental caries was 66.3%. Among the children with caries, 88.0% had active lesions. Dental caries was more prevalent in girls (OR = 1.53, 95%CI: 1.05-2.23, in children from families with a monthly household income ≤US$312.50 (OR = 2.38, 95%CI: 1.65-3.43 and those whose mothers had up to eight years of schooling (OR = 1.55, 95%CI: 1.07-2.23. Lesion activity was significantly associated with mother's schooling ≤ 8 years (OR = 2.15, 95%CI: 1.15-4.00. The prevalence rates of dental caries and lesion activity were high and mainly associated with a lower socioeconomic status and mother's schooling.

    There is growing interest in the association between anthropometric measurements and dental caries in childhood over time (life-course studies). The aim of this review was to identify and systematically review the evidence of the association between anthropometric measurements and dental caries in childhood over time. PubMed, Institute for Scientific Information (ISI) Web of Knowledge, the Cochrane Library, and 6 other databases were searched to identify effective articles. A systematic approach involving critical appraisal was conducted to examine the relation between anthropometric measurements and dental caries in preschool- and school-aged populations from longitudinal studies. An initial search identified 1338 studies, with 59 potentially effective studies (κ = 0.82) and 17 effective studies (κ = 0.88). The quality of reporting among the studies ranged from 19.5 to 30.0 according to the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) criteria. Among the effective studies, 2 studies in which caries was used to predict anthropometric measurements consistently found an inverse association and 15 studies in which anthropometric measurements were used to predict caries were inconsistent, with results appearing to be influenced by nonuniformity of assessments, setting, and procedure of measurements; age and ethnicity of participants; and confounders of dental caries. In conclusion, among >1000 studies identified, 17 informed this systematic review. The quality of reporting of these studies varied considerably. Evidence of the association between anthropometric measurements and dental caries is conflicting and remains inconclusive. PMID:25593143

    Fluoride mouthrinses have been used extensively as a caries-preventive intervention in school-based programmes and by individuals at home. This is an update of the Cochrane review of fluoride mouthrinses for preventing dental caries in children and adolescents that was first published in 2003. The primary objective is to determine the effectiveness and safety of fluoride mouthrinses in preventing dental caries in the child and adolescent population.The secondary objective is to examine whether the effect of fluoride rinses is influenced by:• initial level of caries severity;• background exposure to fluoride in water (or salt), toothpastes or reported fluoride sources other than the study option(s); or• fluoride concentration (ppm F) or frequency of use (times per year). We searched the following electronic databases: Cochrane Oral Health's Trials Register (whole database, to 22 April 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 3), MEDLINE Ovid (1946 to 22 April 2016), Embase Ovid (1980 to 22 April 2016), CINAHL EBSCO (the Cumulative Index to Nursing and Allied Health Literature, 1937 to 22 April 2016), LILACS BIREME (Latin American and Caribbean Health Science Information Database, 1982 to 22 April 2016), BBO BIREME (Bibliografia Brasileira de Odontologia; from 1986 to 22 April 2016), Proquest Dissertations and Theses (1861 to 22 April 2016) and Web of Science Conference Proceedings (1990 to 22 April 2016). We undertook a search for ongoing trials on the US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the World Health Organization International Clinical Trials Registry Platform. We placed no restrictions on language or date of publication when searching electronic databases. We also searched reference lists of articles and contacted selected authors and manufacturers.

    Dental caries is a common disease in children of all ages. It is desirable to know whether children with primary, mixed and permanent dentitions share risk factors for cavitated and non-cavitated caries. Objective To assess the longitudinal associations between caries outcomes and modifiable risk factors. Methods One hundred and fifty-six children in the Iowa Fluoride Study met inclusion criteria of three dental examinations and caries-related risk factor assessments preceding each examination. Surface-specific counts of new non-cavitated caries and cavitated caries at the primary (Exam 1: age 5), mixed (Exam 2: age 9) and permanent (Exam 3: age 13) dentition examinations were outcome variables. Explanatory variables were caries-related factors, including averaged beverage exposure frequencies, toothbrushing frequencies, and composite water fluoride levels collected from 3–5, 6–8, and 11–13 years, dentition category, socioeconomic status and gender. Generalized linear mixed models (GLMMs) were used to explore the relationships between new non-cavitated or cavitated caries and caries-related variables. Results Greater frequency of 100% juice exposure was significantly associated with fewer non-cavitated and cavitated caries surfaces. Greater toothbrushing frequency and high SES were significantly associated with fewer new non-cavitated caries. Children had significantly more new cavitated caries surfaces at the mixed dentition examination than at the primary and permanent dentition examinations. Conclusions There were common caries-related factors for more new non-cavitated caries across the three exams, including less frequent 100% juice exposure, lower toothbrushing frequency and lower socioeconomic status. Less frequent 100% juice exposures might be associated with higher exposures to several other cariogenic beverages. PMID:22320287

    To evaluate the effect of oral hygiene behaviour, dental anxiety, self assessed dental status and treatment necessity on dental caries status of medical students. The study was conducted among 345 medical students of Udaipur city, India who had provision for free dental services and the study was based on a questionnaire which consisted of two parts, first part containing questions regarding self assessment of dental status and treatment necessity along with oral hygiene behaviour and the later part comprised of Corah Dental Anxiety scale (DAS). Clinical examination was based on the WHO caries diagnostic criteria. Females perceived greater dental anxiety than males. Individuals claiming poor dental status had higher mean decayed, missing and filled teeth (DMFT) score (6.67) than good (2.89) and fair (4.44). The mean decayed component among the anxious students (5.4) was almost twice that of less anxious (2.77) student population. DAS constituted the first major contributor for missing component followed by smoking status which alone explained a variance of 7.1%. The cumulative variance explained by all the independent variables on the DMFT status accounted to 56.4% with self assessed dental status alone contributing a variance of 44.9%. The most significant (P dental status (14.5%). Oral hygiene behaviour, dental anxiety, self assessed dental status and treatment necessity significantly affected the dental caries status of medical students.

    This study sought to determine whether the self-perceived image of a young adult's anterior dental esthetics is linked with periodontal health, dental caries, and oral hygiene practices. Two hundred subjects were assessed via a clinical examination, including intraoral photographs. The subjects were questioned about their demographics and oral hygiene practices and given the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) to measure their self-perceived variables related to dental esthetics. A high PIDAQ score indicates a negative image of one's own dental esthetics, while a low PIDAQ score indicates a positive outlook. A self-perceived negative psychosocial impact of anterior dental esthetics was detected in subjects with higher levels of dental caries and visible gingival inflammation in the anterior region of the mouth.

    Medline, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), LILACS (Latin American and Caribbean Health Sciences), CNKI (China National Knowledge Infrastructure), Wanfang (China) and the South African Department of Health databases were searched. In addition the archives at the WHO Collaborating Centre for Nutrition and Oral Health at Newcastle University and reference lists of reviews were searched and experts contacted for further relevant papers. Intervention, cohort population or cross sectional studies were considered where there was any intervention to alter the intake of sugar or the intake of sugars or change of sugar intake was monitored. The main outcome was caries incidence. The GRADE (Grading of Recommendations Assessment Development and Evaluation) system was used to assess study quality. Separate data abstraction forms were designed for RCTs and observational studies and meta-analyses were to be conducted where possible. Sixty-five papers reporting 55 studies were included. No RCTs were identified. Three studies (four papers) were interventional, eight (12 papers) were prospective cohort, 20 (25 papers) were population based and 24 (25 papers) were cross-sectional. Data variability limited meta-analysis. Of the studies, 42 out of 50 of those in children and five out of five in adults reported at least one positive association between sugars and caries.Five of the eight cohort studies allowed comparison of dental caries development when sugars consumption was equivalent to a level 10% E. All eight studies found higher caries with sugars intake > 10% E compared with dental caries development. There is evidence of moderate quality to show that dental caries is lower when free-sugars intake is Dental caries progresses with age, and the effects of sugars on the dentition are lifelong. Even low levels of caries in childhood are of significance to levels of caries throughout the life course. Analysis of the data suggests that there may be

    Caries incidence and prevalence have decreased significantly over the last few decades due to the widespread use of fluoride. However, an increase in the prevalence of dental fluorosis has been reported simultaneously in both fluoridated and non-fluoridated communities. Dental fluorosis occurs due to excessive fluoride intake during the critical period of tooth development. For the permanent maxillary central incisors, the window of maximum susceptibility to the occurrence of fluorosis is the first 3 years of life. Thus, during this time, a close monitoring of fluoride intake must be accomplished in order to avoid dental fluorosis. This review describes the main sources of fluoride intake that have been identified: fluoridated drinking water, fluoride toothpaste, dietary fluoride supplements and infant formulas. Recommendations on how to avoid excessive fluoride intake from these sources are also given. Copyright © 2011 S. Karger AG, Basel.

    In vitro studies show that milk or milk components may have cariostatic properties. However, the results of epidemiological studies on the association between intake of dairy products and dental caries have been inconsistent. The purpose of this cross-sectional study was to examine the association between intake of dairy products and the prevalence of dental caries in young children. Study subjects were 2058 Japanese children aged 3 years. Information on diet was assessed with a self-administered brief diet history questionnaire for children. The consumption of dairy products was categorized into 3 levels in order to represent the tertiles as closely as possible. Dental caries was assessed by a visual examination. Adjustment was made for sex, toothbrushing frequency, use of fluoride, between-meal snack frequency, maternal smoking during pregnancy, environmental tobacco smoke exposure at home, and paternal and maternal educational levels. Compared with yogurt consumption at the lowest tertile ( or =4 times/week) was significantly associated with a lower prevalence of dental caries, showing a clear dose-response relationship (adjusted prevalence ratio=0.78, 95% confidence interval: 0.62-0.98, P for trend=0.04). There were no material associations between intake of cheese, bread and butter, or milk and the prevalence of dental caries. These data suggest that a high consumption of yogurt may be associated with a lower prevalence of dental caries in young children. Copyright 2010 Elsevier Ltd. All rights reserved.

    Scientific advances in cariology in the past 150 years have led to the understanding that dental caries is a chronic, dietomicrobial, site-specific disease caused by a shift from protective factors favoring tooth remineralization to destructive factors leading to demineralization. Epidemiologic data indicate that caries has changed in the last century; it now is distributed unequally in the U.S. population. People who are minorities, homeless, migrants, children with disabilities and of lower socioeconomic status suffer from the highest prevalence and severity of dental caries. Scientific advances have led to improvements in the prevention, diagnosis and treatment of dental caries, but there is a need for new diagnostic tools and treatment methods. and Future management of dental caries requires early detection and risk assessment if the profession is to achieve timely and cost-effective prevention and treatment for those who need it most. Dental professionals look forward to the day when people of all ages and backgrounds view dental caries as a disease of the past.

    The aim of this study was to assess the correlates of income and income inequality with dental caries in a sample of all countries, as well as in rich countries alone. In this ecological study, the authors analyzed national data on income, income inequality and dental caries from 48 countries. Of them, 22 were rich countries (according to World Bank criteria). The authors determined income by gross national income (GNI) per capita (formerly known as gross national product) and income inequality by the Gini coefficient (a measure of income inequality on a scale between 0 and 1). They assessed dental caries according to the decayed, missing, filled teeth (dmft) index in 5- to 6-year-old children. The authors used Pearson and partial correlation coefficients to examine the linear associations of income and income inequality with dental caries. GNI per capita, but not the Gini coefficient, was inversely correlated with the dmft index in the 48 countries. However, the results showed an opposite pattern when analyses were restricted to rich countries (that is, the dmft index was significantly correlated with the Gini coefficient but not with GNI per capita). These findings support the income inequality hypothesis that beyond a certain level of national income, the relationship between income and the population's health is weak. Income inequality was correlated more strongly with dental caries than was income in rich countries. Among rich countries, income inequality is a stronger determinant of childhood dental caries than is absolute income.

    Metabolic disturbances in diabetes mellitus can affect oral health. Altered levels of salivary lipids have been suggested as a risk for dental caries. There has been lack of research in this regard and in children with type 1 diabetes mellitus. To assess the salivary triglycerides and cholesterol levels in children with type 1 diabetes mellitus and correlate them with their dental caries status. Thirty children aged 12-16 years with type 1 diabetes mellitus and 30 age- and gender-matched healthy children were included in the study. Unstimulated saliva was collected from each child and evaluated for salivary triglyceride and cholesterol levels. Dental caries status (DMFT) was recorded. Salivary cholesterol and triglyceride levels were significantly higher in children with type 1 diabetes mellitus (p ≤ 0.05). In comparison to controls, mean DMFT score was higher in the diabetic children. Salivary triglycerides showed a significant correlation with dental caries status in the study group (p = 0.035). In normal children, salivary cholesterol levels showed a significant association with dental caries. (p = 0.008). Both salivary cholesterol and triglycerides levels were significantly higher in children with type 1 diabetes mellitus. Salivary triglycerides showed a significant association with dental caries in these children. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

    2012-01-01

    The objective The authors undertook an updated systematic review of the relationship between body mass index and dental caries in children and adolescents. Method The authors searched Medline, ISI, Cochrane, Scopus, Global Health and CINAHL databases and conducted lateral searches from reference lists for papers published from 2004 to 2011, inclusive. All empirical papers that tested associations between body mass index and dental caries in child and adolescent populations (aged 0 to 18 years) were included. Results Dental caries is associated with both high and low body mass index. Conclusion A non-linear association between body mass index and dental caries may account for inconsistent findings in previous research. We recommend future research investigate the nature of the association between body mass index and dental caries in samples that include a full range of body mass index scores, and explore how factors such as socioeconomic status mediate the association between body mass index and dental caries.

    This study analyzed how oral hygiene (i.e., brushing, rinsing, and flossing) influences the trajectories of dental caries (i.e., numbers of decayed, missing, and filled teeth) among older Americans within the context of social stratification. Data came from Piedmont Dental Study that involved a sample of 810 older Americans who were dentate in 1988 with up to four repeated observations through 1994. Hierarchical linear models were used for data analysis. Brushing, flossing, and rinsing were associated with the trajectories of dental caries in distinct ways. In addition, oral hygiene was correlated with race, education, household income, and use of dental care. The effects of brushing and flossing on decayed and missing teeth remained robust, even when socio-demographic and health attributes were controlled. Conversely, socioeconomic disparities in dental caries persisted, when oral hygiene was adjusted. Both social stratification and oral hygiene need to be considered in promoting oral health. © The Author(s) 2014.

    Previous studies have demonstrated that the presence of lactic acid bacteria (LAB), especially those classified into the genus Lactobacillus, is associated with the progression of dental caries in preschool children. Nevertheless, the kinds of species of LAB and the characteristics that are important for dental caries have been unclear. The aims of this study were: (1) to investigate the distribution of oral LAB among Japanese preschool children with various prevalence levels of caries; and (2) to reveal the characteristics of these isolated LAB species. Seventy-four Japanese preschool children were examined for caries scores and caries progression, and their dental cavity samples were collected for LAB isolation and identification. The saliva-induced agglutination rate and the resistance to acidic environments of the identified strains were measured. Statistical analysis showed that preschool children carrying Lactobacillus (L.) salivarius or Streptococcus mutans have a significantly higher prevalence of dental caries, the growth ability in acidic environments correlates with the caries scores of individuals with L. salivarius, and the caries scores exhibit positive correlation with saliva-induced agglutination in L. salivarius. These results show that specific Lactobacillus species are associated with dental caries based on the level of carious lesion severity. The present study suggests that these specific Lactobacillus species, especially those with easily agglutinated properties and acid resistance, affect the dental caries scores of preschool children, and that these properties may provide useful information for research into the prevention of dental caries.

    Objective was to evaluate the relationship between physio-chemical properties of saliva such as flow rate, buffering capacity, pH, Streptococcus mutans in saliva and its relationship with dental caries. Eighty children were evaluated for physio-chemical properties of saliva, out which 40 were caries-active (group 1) and 40 caries-free (control group). Caries status of each child was scored by using DMFS and dfs indices to get a combined DMFS and dfs score. The physio-chemical properties were evaluated using Saliva Check (GC Asia Dental Pte Ltd- India) and streptococcus mutans using Dentocult SM Strip Mutans. Flow rate, pH, and buffering capacity of saliva in caries-active children were decreased but not statistically significant. The Streptococcus mutant count of saliva was increased significantly in caries-active children. The physio-chemical properties of saliva like pH, buffering capacity, salivary flow rate, concentration of various components like proteins, calcium and antioxidant defense system play a major role in the development of caries. Hence, more clinical and laboratory studies are needed to determine the exact relationship between these physio-chemical properties of saliva and dental caries.

    The purpose of this paper was to describe the use of dental services and the prevalence of dental caries in children living in Madrid, Spain. A descriptive, cross-sectional study was conducted using data from the Madrid City Health Survey. The questions asked were: (1) When was the last time your child visited the dentist? (2) What was the reason for your child's last visit? and (3) Is your child currently suffering from caries, fillings, or bleeding from the gums when brushing? The independent variables included: sex; age; education level; and nationality. Data from 960 children (approximately 27% of whom were immigrants) were analyzed. Over the last year, approximately 59% of the children had received dental care and 28% suffered from caries. After multivariate analysis, we observed that 3- to 6-year-old children, immigrants, and children of parents with low education levels are more likely not to have received dental care during the last year. We also found that children are more likely to suffer from caries as they get older and if they are immigrants. Being an immigrant and from a lower education level typically results in a less frequent use of dental health services, and children of immigrants have a greater risk of suffering from dental caries. It is essential to investigate the reasons why and introduce strategies to reduce barriers to dental health access among immigrants.

    This publication describes the history of minimal intervention dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the 'surgical' care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI's policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. © 2012 FDI World Dental Federation.

    Much progress has been made in the science of caries risk assessment and ways to analyze caries risk, yet dental education has seen little movement toward the development of frameworks to guide learning and assess critical thinking in caries risk assessment. In the absence of previous proactive implementation of a learning framework that takes the knowledge of caries risk and critically applies it to the patient with the succinctness demanded in the clinical setting, the purpose of this study was to develop a model learning framework that combines the science of caries risk assessment with principles of critical thinking from the education literature. This article also describes the implementation of that model at one dental school and presents some preliminary assessment data.

    Full Text Available Introduction: Dental caries is one of the most prevalent infectious diseases to affl ict humanity. Although caries has multifactorial etiology, inherited genetic behavior and taste threshold may play an important role on caries. Material and Method: Thirty mothers and thirty children in the age group of 6–14 years of both sexes who have stable mental condition and ASA physical status were selected for the study & 6-n-propylthiouracil testing is done. Results: It is observed that nontaster siblings have higher caries prevalence than medium tasters and supertasters. Discussion: Genetic sensitivity to taste is an inherited trait in children from their parents, inheritance from mother being more pronounced. Hence, this study is intended. Conclusion: Dental caries is multi-factorial. No significant correlation between susceptibility of mother and child to genetic sensitivity exists, and genetic sensitivity is not the only criteria for severity.

    Dental caries is the most common microbial disease affecting mankind. Caries risk assessment methods, identification of biomarkers and vaccine development strategies are being emphasized to control the incidence of the largely preventable disease. Pattern recognition receptors such as the toll like receptors (TLR) have been implicated as modulators of host-microbial interactions. Soluble TLR-2 and its co-receptor, CD14 identified in saliva can bind the cell wall components of cariogenic bacteria and modulate the disease process. The objective of this study is to determine the potential of salivary sTLR-2 and sCD14 as biomarkers of caries activity and indirect measures of the cariogenic bacterial burden. Unstimulated whole saliva was collected from twenty caries free and twenty caries active children between the ages of 5 and 13 years. The concentration of sCD14 and sTLR-2 together with that of the cytokine IL-8 reported to be increased in dental caries was assessed by the enzyme linked immunosorbent assay. While the level of sCD14 and that of IL-8 was equivocal between the two groups, the sTLR-2 concentration in caries active saliva was significantly higher than that in caries free saliva. The sTLR-2 in saliva could serve as a potential biomarker for caries activity.

    One of the World Health Organisation (WHO) global health goals stated that the global average for dental caries should not have been more than 3 DMFT at 12 years of age by the year 2000. However, the prevalence of dental caries, gingivitis and dental treatment needs among 12-year-old children in many regions of the developing world had then hardly been investigated. To determine the prevalence of dental caries and gingivitis and the dental treatment needs among 12-year-old children in Kitale Municipality in North- Western Kenya. Descriptive cross-sectional study. Primary schools in Kitale Municipality. Two hundred and ninety two children aged 12 years were randomly selected from eight schools that were also randomly selected. Data were collected according to the WHO Oral Health Survey Methods. The children were examined for decayed (D), missing due to decay (M) and filled teeth and the caries experience using the DMFT index was computed. Gingivitis and treatment needs were assessed using the CPITN index. The overall prevalence of dental caries was 50.3% while its prevalence when only the permanent teeth were considered was 44.5% with a mean DMFT of 0.92 +/-50 1.36. Girls had a significantly higher caries experience (DMFT) than boys (pgingivitis was 77.7%. Out of these 38.7% of the children required professional dental care entailing scaling and oral prophylaxis. The prevalence of dental caries and gingivitis was high hence there was greater need for one surface restoration and full mouth scaling for these children. School based oral health programme to improve oral hygiene of these children is recommended.

The aim of this research was to describe the dental caries in skulls of Pawon Man. The type of the research was descriptive by using purposive sampling. The samples were from four Pawon Man skulls and their teeth. The research was conducted by using clinical examination. All aspects were recorded, collected and presented in tabular form. The result shows that 12.5% of the samples from 32 teeth of skulls of Pawon Man I, III, IV and V had experienced dental caries. Clinical examination shows presence of dental caries in samples of Pawon Man III of  permanent mandibular third molar tooth of region 4(48 in lingual area and buccal lesion of lower left third molar (38. In Pawon IV, lingual lesion of lower left permanent second molar (37 and in lower left permanent third molar (38. All lesions are only in enamel which is code 1 according to ICDAS code. In conclusion, the dental caries in skulls of Pawon Man was low due to their low sugar diets from fruits and sugar-rich plants (fructose sugars. Consumption of hard foods and evidence of presence of animal teeth and mollusks had contributed to the higher percentage of dental attrition compared to dental caries.   Keywords: dental caries, clinical, pawon man

    To assess the association between two intrauterine growth restriction (IUGR) surrogates - IUGR [small for gestational age birth (SGA) and fetal growth restriction (FGR)] and preterm birth with dental caries. Data from the Third National Health and Nutritional Examination Survey (1988-1994) were used, including 2- to 5.9-year-old singletons (n = 3189). Dental caries was defined as presence of any teeth with dental caries (treated or untreated) and also as presence of at least two teeth with dental caries. Exposure variables were preterm birth (education of head of household, breastfeeding, and use of baby bottle. Separate statistical analyses were conducted for IUGR and for preterm birth through the estimation of prevalence ratio (PR), taking complex sampling design into consideration and adjusting for confounders. Sensitivity analysis was conducted including and excluding 2-year-old children and also with the two definitions of dental caries. In general, the inclusion of 2-year-old children and the case definition of presence of any teeth with dental caries biased the results toward the null, but with no major changes in the results. In bivariate analysis, SGA and FGR birth were both negatively but not significantly associated with dental caries while a significant positive association was found for preterm birth. Sensitivity analysis showed that the PR for preterm in bivariate analysis varied from 1.65 (95% CI 1.14-2.40) to 1.84 (95% CI 1.19-2.83). After adjusting for confounders, the PR for preterm birth varied from 1.38 (95% CI 1.00-1.89) to 1.64 (95% CI 1.22-2.20). After adjustment, the PR for SGA varied from 0.79 (95% CI 0.56-101) to 0.66 (95% CI 0.33-0.96). For children from 3 to 5.9 years old, the adjusted PR for FGR using the category 'none' as reference were mild (PR 1.10; 95% CI 0.76-1.58), moderate (PR 0.66; 95% CI 0.26-167), and severe (PR 0.59; 95% CI 0.36-0.99). These values for FGR were very similar for the other models using other classifications of

    Despite great improvements in the oral health of populations across the world, problems still persist particularly among poor and disadvantaged groups in both developed and developing countries. According to the World Oral Health Report 2003, dental caries remains a major public health problem...... in most industrialized countries, affecting 60-90% of schoolchildren and the vast majority of adults. Although it appears that dental caries is less common and less severe in developing countries of Africa, it is anticipated that the incidence of caries will increase in several countries of that continent......, due to changing living conditions and dietary habits, and inadequate exposure to fluorides. Research on the oral health effects of fluoride started around 100 years ago; the focus has been on the link between water and fluorides and dental caries and fluorosis, topical fluoride applications, fluoride...

    Obesity and dental caries are global public health problems which can impact in childhood and throughout the life course. In simple terms, childhood dental caries and body weight are linked via the common risk factor of diet. An association between dental caries and obesity has been described in a number of studies and reviews. However, similarly, a relationship has also been noted between low body weight and caries experience in children. This protocol will provide the framework for an umbrella review to address the following question: Does the available evidence support a relationship between dental caries experience and body weight in the child population? This review protocol outlines the process to carry out an umbrella systematic review which will synthesise previous reviews of childhood dental caries experience and body weight. An umbrella review methodology will be used to examine the methodological and reporting quality of existing reviews. The final umbrella review aims to aggregate the available evidence in order to provide a summary for policymakers and to inform healthcare interventions. PROSPERO CRD42016047304.

    The objective of this study was to determine dental caries frequency and to analyze salivary and bacterial factors associated with active and inactive systemic lupus erythematous (SLE) patients. Also, a proposal to identify dental caries by a surface, teeth, and the patient was developed. A cross-sectional, blinded study that included 60 SLE patients divided into two groups of 30 subjects each, according to the Activity Index for Diagnosis of Systemic Lupus Erythematous (SLEDAI). The decayed, missing, and filled teeth (DMFT) index and Integrative Dental Caries Index (IDCI) were used for analyzing dental caries. The saliva variables recorded were: flow, pH, and buffer capacity. The DNA copies of Streptococcus mutans and Streptococcus sobrinus were estimated by real-time PCR. The caries frequency was 85% for SLE subjects (73.3% for inactive systemic lupus erythematous (ISLE) and 100% for active systemic lupus erythematous (ASLE)); DMFT for the SLE group was 12.6 ± 5.7 and the IDCI was (9.8 ± 5.9). The ASLE group showed a salivary flow of 0.65 compared with 0.97 ml/1 min from the ISLE group; all variables mentioned above showed a statistical difference (p dental caries in epidemiological studies. © The Author(s) 2016.

    Full Text Available Despite the importance of conducting regular epidemiological surveys to monitor dental health in lower socio-economic citizens especially of preschool children, only few papers were published respectively. The aims of this study were to describe preschool children's and their mother's dental caries experiences and to describe mothers' knowledge and behaviors' towards dental health in a suburb area near the capital city of Indonesia. The samples were 152 mother-childpairs with children age less than 5 years old. Intra oral examination by decay-missing-filling-teeth index was performed. Moreover, interviews were conducted to gain information regarding mothers’ oral health behavior and knowledge. 70% children had caries with mean dmf-t= 3.7, consisting 100% of component decay. 90% mothers had caries with DMF-T=7.8, consisting 99% of component decay. More than 50% of mothers had low knowledge and behaviors towards dental health, which comprises of: (1 never checked their children’s dental health, (2 starting to clean their child's teeth after child's age is more than 1 years old, (3 don’t know that caries is an infectious disease, (4 frequently using same feeding and drinking equipments together with their children, (5 considering deciduous teeth are not importantbecause it will be replaced with permanent teeth anyway. It could beconcluded that the prevalence of dental caries in studied sample were high, these were relevant to the findings that the mother's knowledge and behaviors' towards dental health were low. The results of this study demonstrated that mothers might have a high contribution in their child’s caries risk. Prevention should be undertaken at an early age and actively including caregivers is essential in planningand conducting any dental health interventions.

    The objectives of the present study were to establish dental caries prevalence (percentage with caries) and experience in the primary and permanent dentition (dmft and DMFT) of 6 to 13-year-old schoolchildren in Campeche, Mexico, and to estimate the contributing roles of the likely risk indicators. A cross-sectional study was carried out in 1,644 children aged 6-13 years. Self-administered questionnaires obtained information on social, economic, behavioral, and demographic variables. The primary dentition of 1,309 children and the permanent dentition of 1,640 children were evaluated in the oral examinations. The main outcome measures were DMFT, dmft, and SiC indices. Data were modeled using logistic regression analysis. The overall caries prevalence was 77.4%, 73.6% in the primary dentition (61.6% in 6-year-olds), and 49.4% in the permanent dentition. The dmft and DMFT indices were 2.85+/-2.73 and 1.44+/-2.05, respectively (DMFT = 3.11+/-2.62 in 12-year-olds). The SiC index was 6.05 at 12 years of age. Associated variables to dental caries in both dentitions were presence of enamel defects, presence of dental plaque, low socio-economic status, female sex, and older age. Mother's schooling was negatively associated (OR = 0.95) with caries in primary dentition. Caries experience in the primary dentition (OR = 6.02) was positively associated with caries in the permanent dentition. Dental caries status in these Mexican children was closer to the goals proposed by the WHO/FDI for 2000 than previous studies. This study has identified clinical, socio-economic, and behavioral determinants for dental caries in primary and permanent dentition on Mexican schoolchildren.

    The association between dental caries and metabolic syndrome (MetS) is inconsistent. The aim of the present study was to assess the relationship between dental caries and MetS and its components in a middle-aged Chinese population. A cross-sectional analysis was performed of 13 998 participants aged 45-65 years undergoing a health check during 2013-14. An index variable of decayed, missing, and filled teeth (DMFT) was calculated. Logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) after adjustment for sex, age, education level, dietary habits, alcohol use, smoking, physical activity, and periodontitis. Of the 13 998 participants, 6164 had dental caries and 7834 did not; 3571 had MetS, whereas 10 427 did not. Participants with severe caries showed a higher prevalence of MetS, abdominal obesity, elevated blood pressure, dyslipidemia, and hyperglycemia than those with mild or no caries (all P dental caries and those with two or more DMFT were 1.12 (95 % CI 1.14-1.74) and 1.09 (95 % CI, 0.89-1.21), respectively (P trend  caries were associated with MetS among subjects with hyperglycemia (OR 1.14 [95%CI, 0.98-1.34]; P caries and abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, and elevated blood pressure (adjusted ORs [95 % CIs] 0.98 [0.82-1.16], 1.01 [0.85-1.19], 0.84 [0.70-1.00], and 0.96 [0.86-1.13], respectively; all P > 0.05).

    Full Text Available Objective: To determine the history of dental caries and the need for dental treatment of children with visual disabilities 6-12 years, belonging to Chile Special Schools, 2014.Material and Methods: A descriptive cross-sectional observational study. The target population was children with visual disabilities in special schools in Chile. A clinical examination was performed to obtain a deft, DMFT and the need for treatment. Two calibrated examiners performed the visual clinical examination, according to the WHO criteria. Additionally, lesions clinically detectable enamel surfaces cavitated and not cavitated recorded. The recorded data were analyzed using descriptive statistics.Results: Ninety-four children were examined, belonging to 7 special schools. The average dmft was 2.05 (SD±2.6 and DMFT was 0.96 (SD±1.3. At 6 years, the dmft/ DMFT was 3/0 respectively. At 12 years dmft was 0.17 and DMFT was 1.42. Caries prevalence was 56.3%. 95% of children need sealants, 50% need at least a restoration of a face, and 29% restoration of 2 or more surfaces. As for enamel lesions, 34% of children had at least one lesion not cavitated and 48% of them had a cavitated lesion. Conclusion: The history of dental caries is similar to that reported in the general population; however, there is a high need for preventive treatment, so it is necessary to conduct more research to clarify whether these patients have a higher cariogenic risk due to alteration visual, so as to establish promotional / preventive effective strategies.

    The purpose of this article is to review the current status of dental caries diagnosis using cone beam computed tomography (CBCT). An online PubMed search was performed to identify studies on caries research using CBCT. Despite its usefulness, there were inherent limitations in the detection of caries lesions through conventional radiograph mainly due to the two-dimensional (2D) representation of caries lesions. Several efforts were made to investigate the three-dimensional (3D) image of lesion, only to gain little popularity. Recently, CBCT was introduced and has been used for diagnosis of caries in several reports. Some of them maintained the superiority of CBCT systems, however it is still under controversies. The CBCT systems are promising, however they should not be considered as a primary choice of caries diagnosis in everyday practice yet. Further studies under more standardized condition should be performed in the near future.

    The aim of this study was to investigate the association between intermediary social determinants, namely social support and social network with dental caries in adolescents. An adapted version of the WHO social determinants of health conceptual framework was used to organize structural and intermediary social determinants of dental caries into six blocks including perceived social support and number of social networks. A cross-sectional study was conducted with a representative sample of 542 students between 12 and 14 years of age in public schools located in the city of Dourados, Brazil in 2012. The outcome variables were caries experience (DMFT ≥ 1) and current dental caries (component D of DMFT ≥ 1) recorded by a calibrated dentist. Individual interviews were performed to collect data on perceived social support and numbers of social networks from family and friends and covariates. Multivariate Poisson regressions using hierarchical models were conducted. The prevalence of adolescents with caries experience and current dental caries was 55.2% and 32.1%, respectively. Adolescents with low numbers of social networks and low levels of social support from family (PR 1.47; 95% CI = 1.01-2.14) were more likely to have DMFT ≥ 1. Current dental caries was associated with low numbers of social networks and low levels of social support from family (PR 2.26; 95% CI = 1.15-4.44). Social support and social network were influential psychosocial factors to dental caries in adolescents. This finding requires confirmation in other countries but potentially has implications for programmes to promote oral health. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available ABSTRACT Dental caries is one of the dental health problems. Dental caries are formed because there was leftover food that sticks to the teeth, which eventually lead to tooth calcification. Impact, teeth become brittle, hollow, even broken.Dental caries experience a loss of power to make a child chewing and digestive disruption, which resulted in growth of less than the maximum. This study aims to determine the relationship of parents’ behavior towards the maintenance of dental health of children (feeding habits sweet, sticky and drinking milk, teeth maintenance, inspection tooth and mouth with dental caries in the TK R.A Bustanussholihin in Balun village Turi District of Lamongan. This study Analytics whose data is collected with a cross sectional sample of kindergarten children aged 4–6 years with a total sample of 49 children. The collection of primary data through interviews parents TK R.A Bustanussholihin student using questionnaires and secondary data obtained from the agency are in the region of the profile data TK R.A Bustanussholihin in Balun Village of Turi District of Lamongan. This study used a correlation coefficient of contingency. Based on the results of the contingency coefficient correlation test showed that the factors that have a strong relationship is the habit of feeding the sweet, sticky, and drink milk with a value of P = 0.504. While the factors that have a weak link is the habit of maintaining dental hygiene habits of children and child oral examination . From this study it can be concluded that there is a relationship or a strong correlation between feeding habits sweet, sticky and drinking milk with the incidence of dental caries in children aged 4–6. So as to prevent dental caries severity we need to hold counseling on feeding sweet, soft and gooey on the effect of dental caries as well as how it should be formula feeding or breast milk to the child to prevent rampant caries.

    The present study aimed to determine the prevalence of and relationship between dental caries and dental fluorosis at varying levels of fluoride in drinking water. The study was conducted among 3007 school children in the age group of 12 to 16 years in 2 districts of Haryana having varying fluoride levels in drinking water. Type III examination for dental caries according to the WHO index and dental fluorosis estimation according to Dean's index was done. The prevalence of dental caries decreased from 48.02% to 28.07% as fluoride levels increased from 0.5 to 1.13 ppm, but as the fluoride level increased further to 1.51 ppm, there was no further reduction in caries prevalence, but there was a substantial increase in fluorosis prevalence. The optimum level of fluoride in drinking water was found to be 1.13 ppm, at which there was maximum caries reduction with minimum amount of esthetically objectionable fluorosis. © 2012 APJPH.

    Dental caries and trauma are the most common oral health problems for many decades. There is need for prevalence data to analyze the nature of the problems and to take necessary steps in improving public health. To assess the prevalence of dental caries and traumatic dental injuries among schoolchildren of age 6 to 12 years in Bhopal city. Cross-sectional study design was selected. Universal sampling method was followed in this study. A total of 1,204 children were examined. The distribution of samples was done based on age, gender, residing area, and type of school. Data were collected and statistically evaluated under chi-square test and analysis of variance. The overall caries experience (73.17%) was found to be higher than that of traumatic injury experience (20.9%). There was age-related correlation between age and decay, missing, and filled teeth score. Since most injuries occur at home or at school, educating the individual is the key that will have a great impact on the prognosis of traumatic injuries. Also good food habits need to be instilled in children from a tender age with the help of parents, which is the ultimate solution to fight caries.

    To estimate the prevalence of dental caries and treatment needs in 12-year-olds and adolescents. Cross-sectional study based on results from the epidemiological surveys: Oral Health Conditions in the State of Sao Paulo, 2002 and the Brazilian Oral Health Survey (SBBrasil) 2010. Secondary data for 5,782 (2002) and 369 (2010) 12-year-olds and 880 (2002) and 300 (2010) 15- to 19-year-olds were analyzed. Dental caries attack was evaluated using the DMFT (decayed, missing or filled teeth) index and the need for treatment verified using the criteria proposed by the World Health Organization. The Significant Caries Index was used to measure the severity of the decay in the tercile of the group with the highest prevalence of the disease. In order to analyze the results, the Chi-squared and Mann-Whitney tests were used, with a 5% significance. There was a decrease of 39.3 percentage points in the DMFT index for 12-year-olds (p caries respectively. The percentage of restored teeth decreased in both age groups, although the prevalence of dental caries did not change in the group more affected by dental caries. In the group with few dental caries, there was a decrease in the component 'tooth loss' for adolescents and increase in the component 'decayed teeth' for the 12-years-old and the adolescents. There was an increase in the need for dental treatment in the group as a whole and in the group of 12-year-olds more affected by dental caries; and among the adolescents, the need for restoration on two or more surface decreased in the group as a whole and also in the group which suffered least from dental caries. The decreasing need for non-complex treatment in adolescents suggests that promotion and prevention activities are having a positive effect on this group. Moreover, the two epidemiological surveys in the state of Sao Paulo show improvements in oral health conditions in both age groups studied and calls for monitoring aimed also at the group least affected by dental caries.

    This study aimed to assess dental caries status and associated factors in Uruguayan adults and elders using data from the first Uruguayan National Oral Health Survey. Data were representative of the country as a whole. Socio-demographic information was collected with a closed questionnaire. Dental caries was assessed by clinical examination using the DMFT index. The final sample consisted of 769 participants. Mean DMFT was 15.20 and 24.12 for the 35-44 and 65-74-year age groups, respectively. Mean number of decayed teeth was 1.70 in adults and 0.66 in elders. Multivariate analyses showed higher prevalence of dental caries associated with age 65-74 years, low socioeconomic status, use of public dental services, presence of gingivitis; for decayed teeth, age 35-44 years, low socioeconomic status, use of public dental services, infrequent tooth brushing, need for oral health care, and presence of root caries showed higher severity. Uruguayan adults and elders from disadvantaged backgrounds concentrated a heavier burden of dental caries.

    Objectives The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. Methods A community-based, cross-sectional study among 2376 elderly subjects (age: 65–74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). Results 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Pcaries accounted for 2.08% with a rate higher in urban areas (Pcaries. Conclusions The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries. PMID:24260129

    This publication describes the history of Minimal Intervention Dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the ‘surgical’ care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI’s policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. PMID:23106836

    To determine if there is an association between longer breast-feeding duration and dental caries in healthy urban children. We conducted a cross-sectional study of urban children aged 1 to 6 years recruited through The Applied Research Group for Kids (TARGet Kids!) practice-based research network between September 2011 and August 2013. The main outcome measure was parental report of dental caries. The adjusted predicted probability of dental caries was 7%, 8%, 11%, and 16% with total duration of breast-feeding duration of 12, 18, 24, and 36 months, respectively. In the adjusted logistic regression analyses, relative to breast-feeding 0 to 5 months, the odds of dental caries with total breast-feeding duration >24 months was 2.75 (95% confidence interval 1.61-4.72). Among healthy urban children, longer breast-feeding duration was associated with higher odds of dental caries. These findings support heightened awareness and enhanced anticipatory guidance for preventive dental care, particularly among children who breast-feed beyond 2 years of age.

    Carious lesions are distributed nonuniformly across tooth surfaces of the complete dentition, suggesting that the effects of risk factors may be surface-specific. Whether genes differentially affect caries risk across tooth surfaces is unknown. We investigated the role of genetics on two classes of tooth surfaces, pit and fissure surfaces (PFS) and smooth surfaces (SMS), in more than 2,600 subjects from 740 families. Participants were examined for surface-level evidence of dental caries, and caries scores for permanent and/or primary teeth were generated separately for PFS and SMS. Heritability estimates (h2, i.e. the proportion of trait variation due to genes) of PFS and SMS caries scores were obtained using likelihood methods. The genetic correlations between PFS and SMS caries scores were calculated to assess the degree to which traits covary due to common genetic effects. Overall, the heritability of caries scores was similar for PFS (h2 = 19–53%; p caries scores for both PFS and SMS in the primary dentition was greater than in the permanent dentition and total dentition. With one exception, the genetic correlation between PFS and SMS caries scores was not significantly different from 100%, indicating that (mostly) common genes are involved in the risk of caries for both surface types. Genetic correlation for the primary dentition dfs (decay + filled surfaces) was significantly less than 100% (p caries risk in PFS versus SMS in the primary dentition. PMID:22286298

    Associations between childhood lead exposures and dental caries in children have been reported for over 30 years, with widely varying findings and conclusions, and using measures of lead exposure which ranged from food sources and water to tooth, hair or blood lead concentrations. This study examined the relationship of lead exposure and dental caries in a population of normatively healthy children. This cross-sectional study used a population of 507 children aged 8-12 who were participating in a clinical trial of dental materials to examine the relationship between lead and caries. Blood lead concentrations and dental caries were examined for association in both primary and permanent teeth. Because it is possible that neurobehavioral status could be associated with both lead exposure and dental caries prevalence, we also examined neurobehavioral status of the subjects. A gender-specific association (males only) between lead exposure and dental caries was found in primary teeth only. Neurobehavioral measures and IQ were not associated with caries status in this population. This study did not support neurobehavioral status as mediating any association between lead exposure and caries in a normatively healthy population. A gender-specific association between lead and caries not previously reported was found in primary teeth, and no biological explanation for this has been suggested. We conclude that this study provides only weak evidence, if any, for an association of low-level lead exposure with dental caries.

    Full Text Available Abstract Background Maternal nutrition status during pregnancy may affect fetal tooth development, formation, and mineralization, and may affect dental caries susceptibility in children. We investigated the association between maternal intake of dairy products and calcium during pregnancy and the risk of childhood dental caries. Methods Subjects were 315 Japanese mother-child pairs. Data on maternal intake during pregnancy were assessed through a diet history questionnaire. Outcome data was collected at 41–50 months of age. Children were classified as having dental caries if one or more primary teeth had decayed or been filled. Results Higher maternal cheese intake during pregnancy was significantly inversely associated with the risk of dental caries in children, showing a clear inverse dose–response relationship; the adjusted odds ratio (OR in comparison of the highest tertile with the lowest was 0.37 (95 % confidence interval [CI]: 0.17-0.76, P for trend = 0.01. The inverse associations between maternal intake of total dairy products, yogurt, and calcium during pregnancy and the risk of childhood dental caries were of borderline significance: the adjusted ORs for the highest tertile of total dairy products, yogurt, and calcium were 0.51 (95 % CI: 0.23-1.09, P for trend = 0.07, 0.51 (95 % CI: 0.23-1.10, P for trend = 0.07, and 0.50 (95 % CI: 0.23-1.07, P for trend = 0.08, respectively. There was no evident relationship between maternal milk intake and the risk of childhood dental caries. Conclusion These data suggested that high intake of maternal cheese during pregnancy may reduce the risk of childhood dental caries.

    This study was undertaken to investigate and analyze the significance of dermatoglyphics in predicting the susceptibility of individuals to develop dental caries. This case-control study was conducted on 1250 children in the age group of 5 to 12 years from Chennai Corporation School, Vadapalani, Chennai. Out of 1250 subjects, 625 subjects were in the study group and the remaining 625 subjects were the control group. The study group included children with dental caries in 5 or more teeth based on the DMFT index performed and control group consisted of normal, healthy children without any dental caries. The finger and palmar prints of both hands were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and configurational types were classified according to the topological method. Statistical analysis was performed using nonparametric tests and t-test to compare the dermatoglyphic pattern changes between the study group and the control group and was applied for each variable, to compare the proportions, and p-value. (1) Dental caries susceptibility of an individual increases with an increase in the incidence of whorl pattern (83% correlation). (2) All the variables show statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among study and control group. (3) The dermatoglyphic patterns are efficient and can predict in assessing the risk of susceptibility to dental caries in study group. The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of loop pattern. The dermatoglyphic patterns may be utilized effectively to study the genetic basis of dental caries. In a developing country like India, it might prove to be a noninvasive, inexpensive and effective tool for screening.

    To evaluate the influence of social inequalities of individual and contextual nature on untreated dental caries in Brazilian children. The data on the prevalence of dental caries were obtained from the Brazilian Oral Health Survey (SBBrasil 2010) Project, an epidemiological survey of oral health with a representative sample for the country and each of the geographical micro-regions. Children aged five (n = 7,217) in 177 municipalities were examined and their parents/guardians completed a questionnaire. Contextual characteristics referring to the municipalities in 2010 (mean income, fluorodized water and proportion of residences with water supply) were supplied by the Fundação Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics). Multilevel Poisson regression analysis models were used to assess associations. The prevalence of non-treated dental caries was 48.2%; more than half of the sample had at least one deciduous tooth affected by dental caries. The index of dental caries in deciduous teeth was 2.41, with higher figures in the North and Northeast. Black and brown children and those from lower income families had a higher prevalence of untreated dental caries. With regards context, the mean income in the municipality and the addition of fluoride to the water supply were inversely associated with the prevalence of the outcome. Inequalities in the prevalence of untreated dental caries remain, affecting deciduous teeth of children in Brazil. Planning public policies to promote oral health should consider the effect of contextual factors as a determinant of individual risk.

    The objective of this study was to compare clinical examination of of dental caries and secondary caries with panoramic examination, and to examine bone lesions and dental anomaly of unerupted state. In this study, clinical records and panoramic radiographs were available for 89 first grade students in elementary school. Dental caries of occlusal surfaces, proximal surfaces, and buccolingual surfaces were examined. Secondary caries was examined too. In addition, the central lesion and dental anomaly of unerupted state were examined in panoramic radiographs. The obtained results were as followed :1. Carious detectability of clinical examination in occlusal and buccolingual surface was higher than that of panoramic examination, but it is statistically insignificant (p>0.05). In proximal surface, carious detectability of panoramic examination was higher than that of clinical examination, and it is statistically significant (p<0.01). 2. In contrast to clinical examination only, when the two examination methods were combined, there was additional detection of dental caries (26.7% in occlusal surface, 48.2% in proximal surface, 33.3% in buccolingual surface, and 38.3% totally). 3. In detection of secondary caries, panoramic examination had lower ability than clinical examination in all three surfaces, but in case that both methods were combined, totally 36.0% extra carious lesions were detected. 4. In panoramic examination, detectability of secondary caries in upper teeth is lower than lower teeth. 5. In panoramic examination, it was possible to detect the central lesions and dental anomalies of unerupted state which cannot be detected in clinical examination. It is useful to combine the panoramic examination with clinical examination in order to increase carious detectability and to evaluate the central lesions and dental anomalies of unerupted state.

    Dental caries is one of the most prevalent diseases of childhood in developing countries. However, there is a paucity of epidemiological data on the prevalence and associated factors of dental caries in Eritrea. The objective of this study was to assess the prevalence and associated factors of dental caries among 12 years old school children in Eritrea. A school based cross sectional study was conducted among 225 twelve years old students in two selected schools. One school from randomly selected urban and rural subzones of the country were selected. WHO adopted questionnaire and a standard checklist were used to collect relevant data. To assess dental caries, two examiners were calibrated by a certified dentist and inter observer agreement was calculated using the Cohen's Kappa statistic (0.82). All data analysis was done using SPSS version 20. The prevalence of dental caries was 78%, without significant difference between males (78%) and females (79%).The mean DMFT value was 2.50 (±2.21). The decayed component contributed 98.3% of the score as it had 2.44 (±1.2) share to the mean DMFT value. The first molar was the most affected tooth with a DMFT value of 1.55 (±1.36). The mean significant caries index score (SiC) was 4.97 (±1.9) which is higher than the upper limit of SiC value of 3 set by the WHO as a global average. More than half of the respondents had never visited a dentist and out of the students who had utilized a dental health facility, 82% of visits were due to dental pain while visits for regular checkups were cited by only 6.6% of the respondents. Dental caries was found to be a common public health problem among 12 years old Eritrean students. The prevalence of dental caries, mean DMFT and SiC scores were higher than the average score of other developing countries. Gaps in dental health service utilization, dental health practices and suboptimal water fluoride levels contribute to poor dental health among school children in Eritrea.

    Context Dental caries is a common oral disease among children. There are various factors that influence caries development. Parents and family environment influence oral health behaviours among children. Dental Anxiety is a common hindrance in seeking dental treatment. Mothers’ dental anxiety may act as a barrier to seek professional advice about their children’s caries experience. Aim To evaluate dental anxiety among mothers and its possible relationship with caries experience in their children in Udaipur city, India Setting and Design The sample was selected from those attending Darshan Dental College and Hospital, Udaipur for dental treatment. The study period was from June 2014 to November 2014. Materials and Methods A cross-sectional survey was designed. A total of 187 mother-child pairs were recruited for the study. The children’s age ranged from 3-14 years. Modified Dental Anxiety Scale (MDAS), Hindi version, was used to evaluate dental anxiety among the mothers that categorizes the dental anxiety into five levels. Demographic detail such as age, educational level, and family income was also collected. The World Health Organization (WHO) criteria was utilized for the diagnosis of dental caries in children. DMFT (Decayed, missing and filled teeth) and DMFS (Decayed, missing and filled surfaces) scores were then calculated. Statistical Analysis Statistical Package for Social Sciences (SPSS) version 20.0 was used to interpret data. Maternal anxiety scores taken as mean MDAS were compared with various independent variables. Statistical tests were used to compare maternal anxiety and children’s caries experience. A p value equal or less than 0.05 was considered as statistically significant. Results Almost half (49.7%) of the mothers reported as being ‘fairly anxious’ or ‘very anxious’. There was a significant (p=.001) difference in maternal dental anxiety level in relation to age of the children. Mothers of younger children reported higher anxiety

    The purpose of this study was to investigate the effects of low power red laser associated with acidulated phosphate fluoride on the development of induced-dental caries in rats. Dental caries were induced in molars of 40 rats divided into five groups: control group (CG), the teeth were not submitted to any treatment; laser group (LG), teeth were irradiated with a low power red laser (LPRL), power of 30 mW and dose of 5 J/cm(2); fluoride group (FG), teeth were treated with topical acidulated phosphate fluoride (APF) 1.23% applied for 4 min; laser+fluoride group (LFG), teeth were irradiated with LPRL followed by APF; fluoride+laser group (FLG), teeth were treated with APF followed by LPRL. The animals were killed after 48 days, and the first and second molars were extracted to analyze the caries lesion area, microhardness, and calcium and phosphorus ratio. There were no statistical differences among FG, LFG, and FLG regarding to caries area and microhardness, although the caries area were smaller in LFG. Ca/P ratio did not show significant differences among all groups. Although LPRL before APF application appeared to diminish the caries progression, LPRL did not present any additional benefit compared with acidulated phosphate fluoride on the prevention of induced-dental caries in rats.

    To investigate the relationship between maternal depression and childhood caries in a cohort of adolescent mothers. This cross-sectional study nested in a cohort evaluated a sample of 538 mother/child dyads. When the children were 24-36 months of age, data regarding oral health from children and mothers were collected by clinical dental examination. A mother's major depressive disorder was assessed by using the Mini International Neuropsychiatric Interview (MINI [Plus]), at the current moment. Independent variables were obtained by using questionnaires. The outcome on dental caries experience was dichotomized by using 2 cut points: dmfs ≥1 and dmfs ≥3. Poisson regression analysis, using a hierarchical approach, was applied to assess the association between major depressive disorder in mothers with and those without caries experience and the outcome. The prevalence of dental caries in children was 15.1% (n = 82). The mean dmfs index was 1.12 (SD = 3.72). The prevalence of major depressive disorder was 32.6% (n = 168). An interaction between caries status and depressive disorder was found, and after adjusted analysis, children from mothers with major depressive disorder with negative caries experience presented a higher caries prevalence (prevalence ratio 4.00, 95% confidence interval 1.29-12.41). Our findings suggest that maternal psychiatric disorders could have a negative impact on children's oral health. © 2016 S. Karger AG, Basel.

    Molar incisor hypomineralization is a developmental defect of dental enamel associated with rapid caries progression. In order to discover whether molar incisor hypomineralization predisposes to dental caries, a cross-sectional cohort study was conducted in a sample of 414 children aged between eight and nine years. It was found that 24.2% of the children presented molar incisor hypomineralization. Of these, 72% had a mild form and 28% a severe form. Caries prevalence was greater among the children with severe form (60.7%) than in those with mild form (43.1%) or no molar incisor hypomineralization (45.5%). The caries indices were higher in out molar incisor hypomineralization (1.18) or with mild form (1.08). The tooth-surface caries ratio was significantly higher in surfaces with severe hypomineralization than in those with no hypomineralization or mild hypomineralization. A linear regression model showed that cariogenic food intake and the presence of severe molar incisor hypomineralization were significantly associated with DMFS. Consequently, an association was found to exist between dental caries and the presence of surfaces affected by severe molar incisor hypomineralization, which should be considered a risk factor within the multifactorial etiology of caries.

    This 3-year retrospective controlled clinical trial assessed the effect of a school-based oral health education program on caries incidence in children. A total of 240 students, aged 5 to 7 years, from two public schools in Monte Sião, Brazil, were included in this study. A school-based oral health education program was developed in one of the schools (experimental group), including 120 students, while the 120 students from the other school did not participate in the program (control group). All children were initially examined for dental caries (dmf-t), and after 3 years, 98 children from the experimental group and 96 from the control group were again examined and answered a questionnaire on oral health issues. The between-groups difference in caries incidence on permanent teeth was calculated using Poisson regression analyses. Logistic regression was used to observe the association between caries incidence and other variables. More students from the experimental group stated knowing what was dental caries and declared that they use dental floss daily, but no significant differences in caries incidence was observed between the experimental and control groups. The school-based oral health education program is not adequately efficient to decrease caries incidence after three years, but some issues about oral health knowledge could be slightly improved.

    Dental caries continues to be the most common infectious disease of childhood; however, it is no longer pandemic, but endemic in specific sectors of populations. Therefore, it is important to identify and target patients at risk of developing caries in order to develop specific preventive measures. This study aims to test dental caries risk indicators for significant associations with caries severity. Five separate, small, isolated rural villages in Mexico with varying degrees of caries prevalence were selected for this observational study. A total of 248 children were examined. Risk indicators were assessed via questionnaire and water and salt fluoride analysis. Caries severity was measured by the International Caries Detection and Assessment System (ICDAS-I). Prevalence of caries ranged from 95% to 100% for the five villages. Mean total DMFS (decayed, missing, or filled surfaces-permanent teeth) and dmfs (decayed, missing, or filled surfaces-primary teeth) scores ranged from 2.5 to 5.0 and from 11.3 to 16.9, respectively. Multivariable models showed age and drinking soda between meals to be significantly associated with DMFS, and drinking juice and being female were significantly associated with dmfs. DMFS and dmfs were high in each village, significantly different between villages, and associated with specific risk indicators.

    To examine the spatial clustering of obesity and dental caries in young children in Plymouth, United Kingdom, to evaluate the association between these conditions and deprivation, and explore the impact of neighbourhood-level characteristics on their distribution. Cross-sectional study analysing data from the National Child Measurement Programme (N=2427) and the Local Dental Health Survey (N=1425). The association of deprivation with weight status and caries was determined at individual and area level, using ANOVA and Poisson models. The overall spatial clustering was assessed using a modified version of the Global Moran's I, while clusters were located through Local Indicators of Spatial Association. Spatial autocorrelation was assessed using the variograms of the raw values. Log-linear Poisson models were fitted to assess the significance of neighbourhood characteristics on overweight/obesity and caries distribution. At an individual level, deprivation was not associated with BMI z-scores but was a significant predictor of caries (p⟨0.05). However, at area level, deprivation related to the rates of both conditions. A significant positive autocorrelation was observed across neighbourhoods for caries. The variograms suggested spatial autocorrelations up to 2.5 km and 3 km for overweight/obesity and caries, respectively. Among several neighbourhood characteristics, the proportion of people on benefits was found to be a significant predictor of caries rates. Our results underline the importance of considering geographic location and characteristics of the broader environment when developing strategies to target obesity and caries.

    To evaluate in a systematic review whether the use of dental floss in primary teeth is associated with a reduction in incidence of proximal caries. Searches were performed using the following databases: PubMed MEDLINE, Web of Science, Bireme, Scopus and The Cochrane Library. Only 5 studies were eligible for inclusion. The quality assessment and bias control of the studies were carried out based on the Fowkes and Fulton Guideline. The study concept was first registered in the international prospective register of systematic reviews (PROSPERO). Flossing was professionally performed in one study and self-reported (by parents or by the children) through questionnaires in all other 4 studies. In the first study, the authors concluded that daily interdental flossing resulted in a significant reduction in the incidence of proximal caries in deciduous teeth during a 20-month period. Two cross-sectional studies found that the use of interdental floss did not show any relevant association with the prevalence of caries; one study found that a higher the frequency of flossing was associated with higher caries experience, and the other found an association between severe caries and the use of dental floss, independently of the flossing frequency. There is only one study in the current literature showing evidence of an association between the use of dental floss and proximal caries reduction on primary dentition. However, the use of dental floss should never be discouraged. Healthy habits acquired in childhood continue throughout adult life, with numerous oral- and general-health benefits.

    Lifelong control of disease processes associated with dental caries should be an essential part of the process of care for practicing dental hygienists. The purpose of this study was to identify the knowledge, attitudes and practice behaviors among dental hygienists regarding caries risk assessment (CRA) and management. Utilizing the American Dental Hygienists' Association (ADHA) Survey/Research Center database of all registered dental hygienists in the U.S., 2,500 actively licensed dental hygienists were randomly selected and sent a web-based survey via SurveyMonkey™. The survey included items about practice characteristics and questions regarding knowledge, attitudes and practice behaviors regarding CRA and management. Second and third emails were sent to non-respondents. A 4-point Likert type scale (1=never, 2=sometimes, 3=frequently and 4=always) was used to rate the occurrence of caries management recommendations used in the practice setting. Frequencies and percentiles were used to evaluate demographic, knowledge and attitude information. The response rate was 9% (n=219) - 87% were ADHA members. Participants reported a high level of comfort (89%) in performing CRA, yet only 23% used an established CRA/management instrument. Over-the-counter fluoride dentifrices (70.1%), individualized oral hygiene instructions (86%) and individualized recare intervals (73.7%) were most often used as caries management recommendations, while low-dose fluoride rinses (45%) and prescription strength sodium fluoride gel or paste (42%) were used less frequently. Dental hygienists scored high on knowledge of CRA with the exception of white spot lesions as a risk factor (42%) and efficacy of chlorhexidine in caries management (61%). There is a need to improve practicing dental hygienists' knowledge and involvement in the active management of caries. Focused training in the use of established CRA/management tools should be designed to improve their knowledge and influence practice

    To facilitate the planning of future dental services, this study sought baseline data, relating to caries experience and dental attendance, for Somali children resident in Sheffield, UK. A convenience sample of 4 to 14 year old Somali children was drawn from pupils attending Somali religious education classes, youth groups and selected schools in Sheffield. During 1998 and 1999, 238 Somali children were subjected to a dental examination and a structured interview. The mean age of the study population was 9.4 years with equal male and female distribution. The majority of children (58%) had been born in Somalia compared with 29% in the UK or 13% in another country. Just over half of the sample had English-speaking mothers. The mean dmft for 4 to 6 year olds was 2.12 and 50% demonstrated a past caries experience. In the 7 to 10 year old group, mean dmft was 2.05 and caries had again affected 50% of subjects. Mean DMFT for 11 to 14 year olds was 1.37 and 58% showed evidence of previous caries experience. The mother's reported ability to speak English was a strong predictor of caries experience in the group as a whole. Interestingly, an English-speaking mother was associated with low caries prevalence in young children, but with high caries prevalence in children over the age of 7 years. Finally, only 57% of subjects had seen a dentist within the previous 12 months, and almost half of these visits had been prompted because of a specific problem. It is evident that some Somali children have a high caries experience, with mother's ability to speak English being the greatest predictor of dental disease. Preventive strategies need to be developed for this population and regular dental attendance should be encouraged.

    The frequent and high consumption of sugar products, particularly sucrose, is one of the causative factors of dental caries. Meta-analyses assessing the relationship between sugar intake and dental caries revealed that a restricted sugar intake to less than 10% of the daily energy intake results in substantial health benefits. Sugar consumption in Poland is 2-fold higher than recommended by the WHO. As change in dietary habits is slow, knowledge of whether a gradual reduction of sugar consumption influences beneficially the dental condition is important. Assessment of the relationship between caries experience and sugar consumption in 12-year-old children. The data obtained from the Statistical Agricultural Yearbooks of the Central Statistical Office in Poland regarding the average yearly sugar intake by a person in the years 1995-2013, and caries prevalence (frequency and DMFT) resulting from the national epidemiological studies of the 12-year-old children conducted by the Ministry of Health in those years were analyzed. The data was analyzed by linear regression. Regression function parameters and coefficients of determination were assessed for a possible link between sugar consumption and dental caries frequency and severity was expressed as DMFT value. The mean yearly sugar intake by a statistical Pole ranged from 43.6 kg (2002) to 35.3 kg (2006). Despite a slight trend to lower the sugar consumption, its mean intake in 1995 and 2013 was the same (41.9 kg). Caries frequency and DMFT decreased in 2012 compared to 1995 from 90.5% to 79.6% and from 4.3 to 3.53 kg in 2012, respectively. The increased sugar intake by 1 kg/year caused the increase of caries frequency by 1% and DMFT value by 0.2. Even a relatively low decrease in sugar consumption can exert some beneficial influence on the dental condition in adolescents, particularly upon the severity of caries.

    Full Text Available Caries has traditionally been assessed with WHO criteria including only obvious caries lesions. ICDAS has been developed to detect also the enamel caries lesions. This study aims to study caries and the associations of the number of caries lesions between the permanent and primary molars with ICDAS in the mixed dentition of the first and second grade primary school children. The clinical examinations of 485 children were conducted by four examiners with high reproducibility (inter- and intraexaminer kappas >0.9. The mean number of caries lesions—especially dentine caries—seemed to be higher in the second primary molars than in the first permanent molars. There were significant correlations between the number of lesions on occlusal and lingual surfaces between the primary and permanent molars. Enamel caries lesions, restorations, and caries experience did not increase according to age. Therefore, caries might be increasing in this population. As a conclusion, ICDAS recording seems to give appropriate information from the occurrence of caries lesions and its correlations between the primary and permanent teeth and surfaces.

    To determine whether common polymorphisms in the sweet taste receptor (TAS1R2) and glucose transporter (GLUT2) genes are associated with dental caries, 80 healthy Caucasian individuals aged 21-32 years were genotyped and grouped based on the TAS1R2 (Ile191Val) and GLUT2 (Thr110Ile) polymorphisms. Clinical and radiographic examinations were conducted by a single examiner who was blinded to the genotypes. To assess caries prevalence, three different caries scores were determined: DMFT (decayed, missing, and filled teeth), DMFT + X-ray and ICDAS (International Caries Detection and Assessment System). Associations between genotypes and caries prevalence were analyzed using Student's t test. Based on the genotypes for each of the GLUT2 and TAS1R2 genes, individuals were stratified into four groups for comparison of caries scores. A higher DMFT score (mean ± SE; 4.3 ± 0.4 vs. 6.1 ± 1.2, p = 0.04) was observed among carriers of the Ile allele for GLUT2 (risk group). Carriers of the Val allele for TAS1R2 (resistant group) demonstrated lower caries scores: DMFT (4.1 ± 0.5 vs. 5.8 ± 0.9, p = 0.05), DMFT + X-ray (4.9 ± 0.6 vs. 7.5 ± 0.9, p = 0.01), and ICDAS (19.5 ± 2.2 vs. 26.14 ± 2.82, p = 0.03). Based on genotype stratification, caries scores were significantly lower in the double resistant group as compared to the double risk groups: DMFT (9.1 ± 0.08 vs. 4.2 ± 0.01, p caries risk. Considering the combination of risk/resistance genotypes might further our understanding of genetic predispositions to dental caries and improve the accuracy of caries prediction models.

    To determine the sources of fluoride exposure and the prevalence and severity of fluorosis and dental caries and sources of fluoride exposure in the permanent dentition of 11-year-old children. A cross-sectional study of 111 children attending elementary schools in the State of Mexico, where the concentration of fluoride in drinking water is caries prevalence was 53.2% (95% CI: 50.1-56.3) with DMFT = 1.27 +/- 1.67 (D = 0.85 and F = 0.42). Children who had no fluorosis showed more caries (p = 0.001). Dental fluorosis was associated with the initial age of brushing (before age four), OR = 0.511 (0.338-0.772); frequency of brushing (three times a day), OR = 0.681 (0.483-0.958), brushing before sleeping (yes), OR = 0.664 (0.473-0.932), and applications of fluoride (yes), OR = 0.756 (0.576-0.994). Dental caries was associated with several variables, such as initial age of brushing, OR = 11.28 (4.6-27.7), frequency of brushing, OR = 0.245 (0.109-0.553), brushing before sleeping, OR = 8.03 (3.295-19.59), and applications of fluoride, OR = 14.2 (4.54-44.53). In the final regression model, the level of caries and fluorosis was significantly associated (p = 0.000) with the amount of fluoride exposure. The multivariate shows this relationship. Fluorosis prevalence was high for low levels and low for more severe levels. According to the CFI in the studied example, dental fluorosis represents a public health problem in the studied sample. Dental caries was low with a predominance of tooth decay. Exposure to different sources of fluoride, was a risk factor for the development of fluorosis and a benefit with regard to dental caries.

    The purpose of this study was to examine the risk factors of dental caries at the level of an individual person with survival analysis of the prospective data for 5 years. A total of 249 first-grade students participated in a follow-up study for 5 years. All participants responded to a questionnaire inquiring about socio-demographic variables and oral health behaviors. They also received an oral examination and were tested for Dentocult SM and LB. Over 5 years, the participants received yearly oral follow-up examinations to determine the incidence of dental caries. The incidence of one or more dental caries (DC1) and four or more dental caries (DC4) were defined as one or more and four or more decayed, missing, and filled permanent teeth increments, respectively. Socio-demographic variables, oral health behaviors, and status and caries activity tests were assessed as risk factors for DC1 and DC4. The adjusted hazard ratios (HRs) of risk factors for DC1 and DC4 were calculated using Cox proportional hazard regression models. During the 5-year follow-up period, DC1 and DC4 occurred in 87 and 25 participants, respectively. In multivariate hazard models, five or more decayed, missing, and filled primary molar teeth [HR 1.93, 95% confidence interval (CI) 1.19-3.13], and Dentocult LB of two or three (HR 2.21, 95% CI 1.37-3.56) were independent risk factors of DC1. For DC4, only Dentocult LB of two or three was an independent risk factor (HR 2.95, 95% CI 1.11-7.79). Our results suggest that dental caries incidence at an individual level can be associated with the experience of dental caries in primary teeth and Dentocult LB based on the survival models for the 5-year prospective data. © 2014 John Wiley & Sons A/S.

    Water fluoridation has been cited as one of the top 10 public health achievements of the 20th century. Herein, we analyzed water fluoridation articles related to dental caries published in PubMed between 1950 and 2016 using informetrics and linguistic methods to investigate trends in the studies. To this aim, queries such as "dental caries and (water fluoridation or fluoridated water)," "dental caries and (fluoride or fluoridation)," and "dental caries" were submitted to PubMed to retrieve information about articles on water fluoridation within the area of dental caries and fluoride - their titles, abstracts, publication dates, author affiliations, and publication journals. This article information was then collected by an automatic web crawler and examined through informetrics and linguistic analyses. It was found that the number of articles concerned with water fluoridation and dental caries was 3,381 and declined over time after 1970. The articles were published by 750 journals - most notably, Community Dentistry and Oral Epidemiology and Caries Research. With regard to the geographic distribution of the authors, Europe and North America, especially the USA and UK, accounted for 59.9% of the articles published during the years 1987 to 2015, though there was a sharp increase in the number of authors in Oceania and Asia in recent years. In the titles and abstracts of the articles, "community" and "fluorosis" were mentioned more frequently than the other key terms selected in this study, regardless of the period examined. Our findings may allow one to assess how the research on water fluoridation has evolved over the past several decades. © 2018 S. Karger AG, Basel.

    Staphylococcus epidermidis is one of most prevalent in dental caries or dental pulp which has the capability of horizontal genetic transfer between different bacterial species in the oropharynx, suggesting that it may evolve with the dissemination of resistant determinants, This study was performed to molecularly characterize and differentiate S. epidermidis isolated from dental caries and healthy individual. Also, two important cytokines in inflammation were assayed caused due to S. epidermidis of health and dental caries sources. Dental caries strains were more resistant with high MIC 50 and MIC 90 value. These isolates also showed the presence of mecA gene and another virulence gene i. e sea and seb comparatively more than healthy individual isolates. SCCmec types, III and IV was more prevalent in dental caries isolates where an as healthy individual was more non-typable. Additionally, the quantity of IL-1β and IL-8 caused due to dental caries isolates was seen more which indicate dental caries isolates are able to induce. This study showed that S. epidermidis a normal flora of oropharyngeal are more diverse to those strains which cause dental caries. S. epidermidis owns a prodigious genetic plasticity that permits to obtain, lose or regulate genetic elements that provide compensations to improve its colonization in the host.

    The impact of oral conditions on quality of life in overweight/obesity needs to be elucidated. The aim of this study was to evaluate the association between dental caries activity, quality of life and obesity in Brazilian adolescents. This study was conducted at public schools in Brazil, on a sample of 202 adolescents, 12 years of age. For anthropometric evaluation, the body mass index (BMI)-for-age was used. In oral examinations, the Decayed, Missing, Filled teeth (DMFT), significant caries (SiC) and dental caries activity (DCA) indices were used (κ > 0.94). The Child-Oral Impacts on Daily Performance (Child-OIDP) index was applied. The sample was divided into two groups: O (overweight/obese; n = 101) and N (normal weight; n = 101). For data analysis, chi-square, odds ratio (OR), Wilcoxon and Pearson correlation tests were used (P Obesity, dental caries and quality of life were not correlated. Adolescents with normal weight presented a low perception of the impact of oral conditions on quality of life; however, it seemed to affect psychological aspects in their daily performances. Providing adolescents with nutritional assistance may prevent obesity and dental caries, and improve their quality of life. © 2014 FDI World Dental Federation.

    Leading scientific and organizational prerequisites for the feasibility of clinical examination of the entire child population of the Russian Federation to the dentist is, above all, the high prevalence and intensity of dental diseases in children of all ages. As a result of many years of research and follow-up of children of preschool and school age we have proved the need to distinguish a group of children with zero activity of dental caries. The referring criteria are determined according to the results of comprehensive clinical and laboratory examination in order to determine the degree of risk of dental caries and individual caries resistance. The age-specific risk group is settled by "Stop caries" software. In order to optimize the preventive activities children are divided in 5 groups for routine preventive dental care. Unfortunately the efforts of modern dental services aimed at eliminating the consequences of caries process by filling cavities. Individualized preventive approach will increase the effectiveness of preventive measures and save public funds allocated in the amount of compulsory health insurance for pediatric dentistry.

    This was to evaluate the prevalence of the developmental defects of enamel (DDE) in primary teeth and its association with dental caries. A cross-sectional study with a randomised representative sample was carried out with 1101 children aged 2-5 years enrolled in public preschools (50% prevalence of DDE in primary teeth, a standard error of 3%, and a confidence level of 95%). Three calibrated dentists (K > 0.62) performed clinical examination. Data collected were: sex, age, DDE (Modified DDE Index) and dental caries (WHO). Descriptive analysis, Chi-square test and multinomial logistic regression were applied for data analysis. Among children, 565 (51.3%) were boys; mean age was 3.7 (±0.9 years). The prevalence of enamel defect was 39.1%; the prevalence of diffuse opacities, demarcated opacities and enamel hypoplasia was 25.3, 19.1 and 6.1%, respectively. The prevalence of dental caries was 31.0%, with mean def-t 1.14 (±2.44). Primary teeth with enamel hypoplasia had three times the odds of having dental caries than those with absence of enamel defects (OR = 3.10; 95% CI: 1.91, 5.01). The presence of enamel defects was moderate and associated with dental caries.

    Increasing evidence suggests that socioeconomic factors may be associated with an increased risk of dental caries. To provide better evidence of the association between dental caries in adults and socioeconomic indicators, we evaluated the relation between these two conditions in a thorough review of the literature. Seven databases were systematically searched: Pubmed, Cochrane, Web of Science, Bireme, Controlled Trials, Clinical Trials and the National Institute for Health and Clinical Excellence. No restrictions were placed on the language or year of publication. The search yielded 41 studies for systematic review. Two independent reviewers screened the studies for inclusion, extracted data and evaluated quality using the Newcastle-Ottawa scale. The following socioeconomic indicators were found: educational level, income, occupation, socio-economic status and the community index. These indicators were significantly associated with a greater occurrence of dental caries: the subject’s education, subject’s income, subject’s occupation and the Gini coefficient. A high degree of heterogeneity was found among the methods. Quality varied across studies. The criteria employed for socioeconomic indicators and dental caries should be standardized in future studies. The scientific evidence reveals that educational level, income, occupation and the Gini coefficient are associated with dental caries. PMID:23202762

    The purpose of this study was to evaluated the diagnostic performance of the senior dental students for the proximal dental caries in intraoral radiographs and to compare it with the dental hospital residents, the reference group. It was also investigated the diagnostic performance according to the carious lesion depth. Thirty-five intraoral periapical and bitewing radiographs with 213 proximal surface included in this study were selected from the dental patients at Chonnam National University Hospital. The observers were 181 senior dental students from 5 dental schools and 40 dentists who were second year resident from 5 dental hospitals. They were asked to evaluate the presence ro the absence of the proximal dental caries. The results were as follows : 1. The mean of the hitting rate for the overall observers was 184.51 surfaces and the diagnostic accuracy was 86.62%. 2. The diagnostic performance of the sound proximal tooth surfaces was very high, i.e., 91.5% true negative rate and 8.5% false positive rate. 3. The diagnostic performance of the dentist group was higher than the student group (P<0.05). 4. The proximal dental caries perceptibility increased as the lesion depth increased significantly (P<0.001) except no difference between the carious lesion depth III and IV (P>0.001).

    We present the clinical applicability of fluorescence ratio reference standard (FRRS) to discriminate different stages of dental caries. Toward this, laser-induced autofluorescence emission spectra are recorded in vivo in the 400- to 800-nm spectral range on a miniature fiber optic spectrometer from 65 patients, with a 404-nm diode laser as the excitation source. Autofluorescence spectra of sound teeth consist of a broad emission at 500 nm that is typical of natural enamel, whereas in caries teeth additional peaks are seen at 635 and 680 nm due to emission from porphyrin compounds in oral bacteria. Scatter plots are developed to differentiate sound teeth from enamel caries, sound teeth from dentinal caries, and enamel caries from dentinal caries using the mean fluorescence intensity (FI) and ratios F500/F635 and F500/F680 measured from 25 sites of sound teeth and 65 sites of carious teeth. The sensitivity and specificity of both the FI and FRRS are determined. It is observed that a diagnostic algorithm based on FRRS scatter plots is able to discriminate enamel caries from sound teeth, dentinal caries from sound teeth, and enamel from dentinal caries with overall sensitivities of 85, 100, and 88% and specificities of 90, 100, and 77%, respectively.

    To compare two groups of children with externalising behaviour problems, having low and elevated caries risk, respectively. Those parameters were assessed in relation to behavioural characteristics and family structure, and to compare the caries risk assessment and gender differences in relation to children in general in the Region of Västra Götaland, Sweden. Families (228) with children, aged 10-13 years, participating in parent training programmes, were recruited. Parents provided information through questionnaires regarding parental knowledge and monitoring, family warmth and conflict and family structure. Children's behavioural characteristics, based on the Strength and Difficulties Questionnaire and the Disruptive Behaviour Disorder rating scale, were used as outcome. Data about caries risk assessment were obtained from dental records. Children in the elevated caries risk group showed higher mean values for conduct problems as well as impulsivity. Parents of the children in the elevated caries risk group reported more parental solicitation and less family conflicts. Children with an elevated caries risk lived more often in households with more than two children and had more often a father from a non-Nordic country. There were statistically significant more children with an elevated caries risk in the study group compared to children in general in the Region of Västra Götaland, both totally and within gender. Differences were observed with regard to behavioural characteristics in externalising children with an elevated risk for caries. Increased knowledge regarding behavioural characteristics in externalising children is an important parameter to be considered in caries risk assessment.

    Declarative Title: Improving the efficacy of fluoride therapies reduces dental caries and lowers fluoride exposure. Background Fluoride is delivered to the teeth systemically or topically to aid in the prevention of dental caries. Systemic fluoride from ingested sources is in blood serum and can be deposited only in teeth that are forming in children. Topical fluoride is from sources such as community water, processed foods, beverages, toothpastes, mouthrinses, gels, foams, and varnishes. The United States Centers for Disease Control and Prevention (CDC) and the American Dental Association (ADA) have proposed changes in their long standing recommendations for the amount of fluoride in community drinking water in response to concerns about an increasing incidence of dental fluorosis in children. Current research is focused on the development of strategies to improve fluoride efficacy. The purpose of this update is to inform the reader about new research and policies related to the use of fluoride for the prevention of dental caries. Methods Reviews of the current research and recent evidence based systematic reviews on the topics of fluoride are presented. Topics discussed include: updates on community water fluoridation research and policies; available fluoride in dentifrices; fluoride varnish compositions, use, and recommendations; and other fluoride containing dental products. This update provides insights into current research and discusses proposed policy changes for the use of fluoride for the prevention of dental caries. Conclusions The dental profession is adjusting their recommendations for fluoride use based on current observations of the halo effect and subsequent outcomes. The research community is focused on improving the efficacy of fluoride therapies thus reducing dental caries and lowering the amount of fluoride required for efficacy. PMID:24929594

    Concurrent chemoradiation (CCR) therapy is a standard treatment for patients with locally advanced head and neck cancer (HNC). It is well documented that CCR causes profound acute and late toxicities. Xerostomia (the symptom of dry mouth) and hyposalivation (decreased salivary flow) are among the most common treatment side effects in this cohort of patients during and following treatment. They are the result of radiation-induced damage to the salivary glands. Patients with chronic hyposalivation are at risk for demineralization and dental cavitation (dental caries), often presenting as a severe form of rapidly developing decay that results in loss of dentition. Usual post-radiation oral care which includes the use of fluoride, may decrease, but does not eliminate dental caries associated with radiation-induced hyposalivation. The authors conducted a narrative literature review regarding dental caries in HNC population based on MEDLINE, PubMed, CLNAHL, Cochrane database, EMBASE, and PsycINFO from 1985 to 2014. Primary search terms included head and/or neck cancer, dental caries, dental decay, risk factor, physical symptom, physical sequellea, body image, quality of life, measurement, assessment, cost, prevention, and treatment. The authors also reviewed information from National Institute of Dental and Craniofacial Research (NIDCR), American Dental Association (ADA), and other related healthcare professional association web sites. This literature review focuses on critical issues related to dental caries in patients with HNC: potential mechanisms and contributing factors, clinical assessment, physical sequellea, negative impact on body image and quality of life, potential preventative strategies, and recommendations for practice and research in this area.

    To observe the trends of dental caries and identify risk factors which may be associated with caries among children in Guangxi province between 2011 and 2013. Three age groups of children (3-year-old, 6-year-old, 12-year-old) were selected from 3 urban and rural areas in Guilin, Baise and Beihai of Guangxi province and examined annually from 2011 to 2013.The caries prevalence, mean DMFT/dmft, caries incidence rate and filling rate were recorded. The data was analyzed with SPSS19.0 software package. The caries prevalence, mean DMFT/dmft and caries incidence rate in the 3 groups were increased year by year. The caries prevalence of deciduous teeth in 3-year-old group was 53.2%, 68.7% and 79.1% respectively, and the growth rate was 48.6%; The mean dmft was 2.34, 4.06 and 5.68, and the caries incidence rate increased from 55.9% to 61.2%. In the 6-year-old group, the caries prevalence of permanent teeth was 8.6%, 21.6% and 48.0% respectively, and the growth rate was 458.1%; The mean DMFT was 0.13, 0.34 and 0.99, and the caries incidence rate increased from 15.6% to 36.6%. The caries prevalence of permanent teeth in 12-year-old group was 52.8%, 60.2% and 71.3%, and the growth rate was 35.0%; The mean DMFT was 1.49, 1.92 and 2.96, and the caries incidence rate increased from 26.1% to 46.9%. The frequency of drinking soft drink or sweet, taking sweets at bedtime or after brushing teeth, brushing teeth with help, frequency of brushing, fluoride toothpaste may be the risk factors related to dental caries among children in this study. Dental caries increase fast among children in Guangxi area. It is necessary to take appropriate measures to improve children's oral health.

    The aim of this study was to determine whether a high degree of dental caries severity is associated with the distal and proximal determinants of caries in a group of Brazilian adults aged 35 to 44 years. A population-based case-control study was conducted using two groups-a case group with high caries severity (DMFT ≥ 14) and a control group without high caries severity (DMFT caries severity was associated with regular visits to the dentist, low income, use of private/supplementary dental service and not petitioning the authorities for community benefits. The results of the study underscore the importance of considering distal and proximal factors in the assessment of the severity of dental caries. Greater caries severity persists among low-income families and among groups with a low degree of social cohesion.

    The consumption of water, milk and various sugary drinks and their relationship with the caries experience of a random sample of teenagers aged 14 to 15 years living in New South Wales, Australia was investigated. Data were obtained from both clinical and questionnaire components of the NSW Teen Dental Survey, 2010. The analyses allowed for various demographic and behavioural risk factors using caries experience (DMFT >0) and mean DMFT as the key outcome variables. Males were more likely than females to consume large volumes of sugary drinks. Consuming two or more glasses of sugary drinks per day led to significantly increased caries experience amongst this sample of 14 and 15 year olds. Factors found to be associated with elevated sugary drink consumption included family income, gender, and mother's education level. There is a strong correlation between increased caries experience of NSW teenagers and high levels of consumption of sugary drinks. © 2015 Australian Dental Association.

    The aim of the present study was to investigate the relationships between cariogenic bacterial infection and single nucleotide polymorphisms (SNPs) in candidate genes associated with dental caries, and to explore the factors related to caries in children. Children aged 3 to 11 years were selected. Detection of cariogenic bacteria (Streptococcus mutans, Streptococcus oralis, Streptococcus sobrinus and Lactobacillus) from the plaque of each patient, and SNP analyses of five candidate genes (MBL2, TAS2R38, GLUT2, MMP13 and CA6) were performed using DNA isolated from buccal mucosal cells. The dental caries experience in primary and permanent teeth was determined using the decayed, missing and filled teeth (DMFT) index, and the effects of the observed factors on the DMFT value were analyzed by multiple regression analysis. The results of the multiple regression analysis showed that the DMFT value significantly increased in the presence of S. mutans or S. sobrinus (p caries.

Los niños con antecedentes de caries en la dentición temporal tuvieron mayor probabilidad de presentar caries en la dentición permanente (odds ratio = 2,48; intervalo de confianza del 95%, 1,66-3,79. Conclusión: Se observó una baja prevalencia de caries en la dentición permanente con un alto porcentaje de dientes obturados, a diferencia de lo observado en la dentición temporal. A unos años de las metas propuestas para el año 2000 (FDI/OMS, no se cumplieron los objetivos en los niños de 6 años de edad. Sin embargo, la meta para el año 2000 en niños de 12 años fue satisfactoria. Como en otros estudios, observamos que la experiencia de caries en la dentición temporal se encuentra asociada con la presencia de caries en la dentición permanente.Objective: To determine the prevalence of caries, deft and DMFT indices (sum of decay, messing, and filling tooth in primary and permanent dentition, and the Significant Caries Index (SiC in scholars from Leon, Nicaragua.

    This study was conducted to assess caries treatment thresholds among Japanese dentists and to identify characteristics associated with their decision to intervene surgically in proximal caries lesions within the enamel. Participants (n = 189) were shown radiographic images depicting interproximal caries and asked to indicate the lesion depth at which they would surgically intervene in both high- and low-caries-risk scenarios. Differences in treatment thresholds were then assessed via chi-square tests, and associations between the decision to intervene and dentist, practice, and patient characteristics were analyzed via logistic regression. The proportion of dentists who indicated surgical intervention into enamel was significantly higher in the high-caries-risk scenario (73.8%, N = 138) than in the low-caries-risk scenario (46.5%, N = 87) (p restorative treatment thresholds for interproximal primary caries differ by caries risk. Most participants would restore lesions within the enamel for high-caries-risk individuals (Clinicaltrials.gov registration number NCT01680848). PMID:23053847

    We have previously shown that dental caries may be produced in diabetic rodent models fed with noncariogenic standard diets; however, many studies usually add large amounts of sugar to the diet to induce dental caries. Moreover, the physical properties of cariogenic diets have been reported as an important factor in the formation of caries. The aim of this study was to clarify the effect of the hardness of non-cariogenic diets on the development of dental caries in diabetic rodents. Seven-wee...

    Malnutrition and dental caries in early childhood remain persistent and intertwined global health challenges, particularly for indigenous and geographically-remote populations. To examine the prevalence and associations between early childhood dental caries, parent-reported mouth pain and malnutrition in the Amazonian region of Ecuador, we conducted a cross-sectional study of the oral health and nutrition status of 1407 children from birth through age 6 in the “Alli Kiru” program (2011–2013). We used multivariate regression analysis to examine relationships between severe caries, parent-reported mouth pain measures, and nutritional status. The prevalence of dental caries was 65.4%, with 44.7% of children having deep or severe caries, and 33.8% reporting mouth pain. The number of decayed, missing and filled teeth (dmft) increased dramatically with age. Malnutrition was prevalent, with 35.9% of children stunted, 1.1% wasted, 7.4% underweight, and 6.8% overweight. As mouth pain increased in frequency, odds for severe caries increased. For each unit increase in mouth pain frequency interfering with sleeping, children had increased odds for being underweight (Adjusted Odds Ratio (AOR): 1.27; 95% CI: 1.02–1.54) and decreased odds for being overweight (AOR: 0.76; 95% CI: 0.58–0.97). This relationship was most pronounced among 3–6 year-olds. Early childhood caries, mouth pain and malnutrition were prevalent in this sample of young children. Parent-reported mouth pain was associated with severe caries, and mouth pain interfering with sleeping was predictive of poor nutritional status. We demonstrate the utility of a parsimonious parent-reported measure of mouth pain to predict young children’s risk for severe early childhood caries and malnutrition, which has implications for community health interventions.

    Objectives The aim of this study was to quantify the agreement among individual National Dental Practice-Based Research Network dentists’ self-reported treatment decisions for primary occlusal caries, primary proximal caries, and existing restorations. Methods Five hypothetical clinical scenarios were presented: primary occlusal caries; primary proximal caries; and whether three existing restorations should be repaired or replaced. We quantified the probability that dentists who recommended later restorative intervention for primary caries were the same ones who recommended that existing restorations be repaired instead of replaced. Results Dentists who recommended later restorative treatment of primary occlusal caries and proximal caries at a more-advanced stage were significantly more likely to recommend repair instead of replacement. Agreement among dentists on a threshold stage for the treatment of primary caries ranged from 40 to 68%, while that for repair or replacement of existing restorations was 36 to 43%. Conclusions Dentists who recommended repair rather than replacement of existing restorations were significantly more likely to recommend later treatment of primary caries. Conversely, dentists who recommended treatment of primary caries at an earlier stage were significantly more likely to recommend replacement of the entire restoration. Between-dentist agreement for primary caries treatment was better than between-dentist agreement for repair or replacement of existing restorations. Clinical implications These findings suggest consistency in how individual dentists approach the treatment of primary caries and existing restorations. However, substantial variation was found between dentists in their treatment decisions about the same teeth. PMID:23743181

A cross-sectional study was performed on a sample of 1993 children enrolled in 58 public preschools from Araçatuba City, São Paulo State, Brazil, during 2010. The exams were made using the decayed, missing, and filled teeth index (World Health Organization methodology and detection criteria for non-cavitated lesions. A tested, self-administered questionnaire was sent to parents to obtain information about their socio-behavioral characteristics. Standardization was performed to verify concordance among examiners (kappa = 0.84. The prevalence of cavitated caries lesions was 41.2% (821, and the prevalence of both, cavitated and non-cavitated caries lesions, was 43.9% (875. The means ± standard deviations of the decayed, missing, and filled teeth index for children aged 4, 5, and 6 years were 1.18 ± 2.45, 1.65 ± 2.67, and 1.73 ± 2.77, respectively. Caries were significantly more prevalent in children from families with low incomes and low educational levels. The presence of dental caries was associated with access to dental services (p < 0.05. The associations between both, cavitated and non-cavitated dental caries lesions, and the frequency of oral hygiene were statistically significant. The prevalence of dental caries in preschoolers was strongly associated with factors related to the children's parents. Therefore, information about parents' socio-economic status, behaviors, and attitudes in relation to oral health should be considered when planning prevention and educational programs for the oral health of preschool children.

El objetivo de esta revisión fue comparar los resultados de la evidencia sobre la relación entre obesidad y caries dental en niños, por lo cual se realizó una búsqueda computarizada y sistemática utilizando el término "dental caries" combinado con "obesity", "overweight" y "underweight" en las bases de datos Medline, Embase, Pubmed y Ovid, arrojando 439 artículos, de estos se seleccionaron 15 artículos que cumplieron con los criterios de inclusión y superaron una evaluación de calidad metodológica. Los hallazgos fueron almacenados y organizados en una base de datos, se procesaron y analizaron estadísticamente teniendo en cuenta razones de disparidad y el coeficiente de correlación de Pearson reportados. Se presentó un prevalencia general de caries dental de 49,6 %, para los obesos fue de 52,5 % y para los no obesos de 46,8 %. No se encontró asociación entre caries y obesidad en 9 de 15 estudios. La evidencia consultada sugiere que no existe relación entre obesidad y caries dental en niños, pues la prevalencia de caries no mostró diferencias estadísticamente significantes entre niños obesos y no obesos.

    Full Text Available Background: There is a lack of consensus regarding the relationship between the risk of dental caries and asthma in the child population. Most studies concluded that asthmatic children are at risk of dental caries from the disease status or its pharmacotherapy. The objectives of this study werer to assess the dental caries status of asthmatic patients in the age group of 3-14 years and to examine the possible association of these conditions to various aspects of bronchial asthma and its management. Materials and Methods: The present study is a hospital-based case-control cross-sectional study. One hundred and five asthmatic patients were studied. The children were examined for their dental caries status, and the scores were compared with age-, gender- and socioeconomic status-matched group of 112 nonasthmatic patients selected randomly from public schools (control group. Caries lesions were assessed using decayed, missing, filled teeth/decayed, missing, and filled surfaces (DMFT/DMFS and dmft/dmfs index according to the WHO criteria (1987. Parents or guardians provided information about oral hygiene and dietary habits by direct interview. Asthma-related data (type and form of medication, severity and duration of asthma were collected from medical records and/or parental interview. Results: The mean age of asthmatics was (7.7 ± 3.5 years and (7.8 ± 3.5 for nonasthmatics. The results showed significantly higher prevalence and severity of dental caries among asthmatic group. As comparing asthmatic children using β2-agonists to those children using β2-agonists and corticosteroids, the results revealed that there were no statistically significant differences in caries index between the two groups. In their primary teeth, children with severe asthma had higher dmft/dmfs than children with moderate and mild asthma unlike in the permanent teeth. Form of medication used - an inhaler or a noninhaler combination (syrup and tablets - had no effect on

    To assess dental caries status and oral health related behavior of 12 year old school children in relation to urbanization and gender; to analyze the effect of socio-demographic and behavioral variables on dental caries experience. Study sample comprised 831, 12 year old school children in, India. Caries status was assessed by Decayed, missing, filled teeth (DMFT) index and a 16 item closed ended questionnaire was administered to children for assessing their oral health related knowledge, beliefs and behavior. Mean caries experience and prevalence was 1.94 and 64.9% respectively. Decay was the dominant component of DMFT. Greater proportion of female and urban children presented better oral health knowledge, beliefs and practices. Boys were more liable (OR=1.2, 95% CI=1.10-1.96) for having caries than girls. Children living in rural areas and whose parents were not professionals or semiprofessionals were more likely to experience caries. Children whose mothers were unskilled or house wives were more than twice likely to present caries (OR=2.14, 95% CI-2.03-2.45) than those children whose mothers were skilled or semi-skilled. Children of illiterate fathers and mothers were 1.09 (95% CI, 1.02-1.49) and 1.98 (95% CI, 1.13-1.99) times more likely to have dental caries than those children whose parents had greater than 10 years of education. Children, those who cleaned their teeth less than once a day presented an odds ratio of 1.36 (CI-1.17-1.86) also higher odds of dental caries was observed in children consuming sweets or soft drinks more than once a day. The prevalence and severity of dental caries was low among urban children and girls than their rural and boy counterparts. In general, oral health knowledge, beliefs and practices were low, predominantly in rural and male children. Caries experience was significantly associated with gender, location of residence, brushing frequency, frequency of consumption of soft drinks and sweets, parents' occupation and education.

    2002-06-01

    This study examined the association between chronic medication exposure and 5-year dental caries increment among older people, using a theoretical model whereby xerogenic medication is thought to lead to increased caries by either (i) chronically lowering salivary flow, thus reducing salivary buffering of plaque acids, or (ii) producing the symptoms of dry mouth, leading to symptomatic relief through the use of cariogenic drinks and foodstuffs. Data were obtained from participants remaining at the 5-year follow-up phase of a cohort study of community-dwelling South Australians aged 60 +. Medication information was available at baseline and at 5 years, enabling only those medications taken on both occasions to be included in the analyses. Dental examinations were conducted at baseline and 5 years, and a reversal-adjusted 5-year caries increment was computed. Multivariate modelling was used to control the effects of potential confounders. Of the original sample, 528 (62.3%) remained after 5 years, with those remaining tending to be younger, healthier and less medicated than those lost to follow-up. Five-year coronal caries incidence was 66.9%. The adjusted coronal caries increment (AdjCI) was higher among males and among those taking a beta-blocker or an antiasthma drug for the previous 5 years. The 5-year incidence of root surface caries was 59.3%. A lower root surface AdjCI was associated with taking daily aspirin. Of the medications shown in earlier analyses to predict dry mouth, only the antiasthma drugs were associated with higher caries experience, and they had predicted more severe xerostomia symptoms. This study offers no strong evidence for a medication-caries relationship, as only one of the observed medication-caries associations was explicable in terms of the theoretical model. However, it should be acknowledged that older people taking antiasthma drugs may be at higher risk of coronal caries, possibly through measures taken for the symptomatic relief of

    To examine dental caries development and caries risk factors among preschool African American children from low-income families in Detroit, Michigan, over a 4-year window. Data came from a representative sample of 1021 children (0-5 years) and their caregivers in Detroit. The baseline participants in 2002-2003 (W1) were re-examined in 2004-2005 (W2) and 2007 (W3). Caries was measured using the International Caries Detection and Assessment System. Bivariate and multivariate analyses for repeated data were conducted to explore associations between caries increment outcomes and demographics, access to dental care, oral health-related behaviours, and social and physical environments. The mean number of new noncavitated caries lesions (NCCL) was 2.8 between W1 and W2 and 2.6 between W2 and W3, while the mean number of new cavitated caries lesions (CCL) was 2.0 and 2.0, respectively, during the same time periods. In younger children (risk of new NCCL was associated with child's soda intake and caregiver's age. For the risk of new CCL, significant risk factors included baseline NCCL, baseline CCL, as well as child's age. Baseline caries and child's soda intake were also associated with the risk of developing new decayed, missing and filled tooth surfaces. Higher number of new NCCL relative to CCL was developed among low-income African American children during early childhood. New caries development was associated with baseline caries and child's soda intake. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Severe early childhood caries are a prevalent public health problem among preschool children throughout the world. However, little is known about the microbiota found in association with severe early childhood caries. Our study aimed to explore the bacterial microbiota of dental plaques to study the etiology of severe early childhood caries through pyrosequencing analysis based on 16S rRNA gene V1-V3 hypervariable regions. Forty participants were enrolled in the study, and we obtained twenty samples of supragingival plaque from caries-free subjects and twenty samples from subjects with severe early childhood caries. A total of 175,918 reads met the quality control standards, and the bacteria found belonged to fourteen phyla and sixty-three genera. Our results show the overall structure and microbial composition of oral bacterial communities, and they suggest that these bacteria may present a core microbiome in the dental plaque microbiota. Three genera, Streptococcus, Granulicatella, and Actinomyces, were increased significantly in children with severe dental cavities. These data may facilitate improvements in the prevention and treatment of severe early childhood caries.

    Full Text Available Objective: Excessive weight in children is a major public health concern. The intake of refined carbohydrates, especially sugars and the prevalence of dental caries are well documented in the literature. The purpose of this study was to investigate the relationship between dental caries and BMI in elementary school children.Materials and Methods: The sampling technique used in the present study was a cluster random sampling. A total of 1000 pupils (500 girls, 500 boys aged 6-11 years from 20 private and state elementary schools (10 boys, 10 girls. The weight status was measured in children by assessment of body mass index (BMI (=bodyweight/body height2 kg/m2 corresponding to gender and age-ranked percentages.To assess the caries frequency the decayed filled teeth (DFT index for permanent dentition and the dft index for primary dentition were used since they give good perception about the situation of tooth caries in young patients.Results: The highest mean total dft/DFT was seen in normal weight and lowest average in at risk of overweight children. There was not a statistically significant relationship found between high weight and caries frequency in the first (p=0.08 and permanent dentitions (p=0.06.Conclusion: The results of this preliminary study do not support an association between dental caries and obesity.

    Full Text Available This study aimed to assess whether birth weight is associated with dental caries during the teenage period. In this register-based cohort study, all children of 13 years of age (n = 18,142 who resided in the county of Stockholm, Sweden, in 2000, were included. The cohort was followed until individuals were 19 years of age. Information regarding dental caries was collected from the Public Health Care Administration in Stockholm. Data concerning prenatal and perinatal factors and parental socio-demographic determinants were collected from the Swedish Medical Birth Register and National Registers at Statistics Sweden. The final logistic regression model showed that birth weight ≥4000 g, adjusted for potential confounders, was significantly associated with caries increment (DMFT ≥ 1 (D = decayed, M = missing, F = filled, T = teeth between 13 and 19 age (OR, 1.22; 95% CI = 1.09–1.36. The relatively enhanced risk OR was further increased from 1.22 to 1.43 in subjects with birth weight ≥4600 g. On the contrary, subjects with birth weight <2500 g exhibited a significantly lower risk (OR, 0.67; 95% CI = 0.50–0.89 for exhibiting caries experience (DMFT ≥ 4 at 19 years of age. In conclusion, high birth weight can be regarded as a predictor for dental caries, and especially, birth weight ≥4500 g is a risk factor for caries increment during adolescence.

    The objective of this study was to prove the association between dental caries and single nucleotide polymorphisms (SNPs) in the ENAM gene. The research was carried out in 96 children (48 with caries and 48 counterparts free of this disease), aged 20-42 months, with 11-20 erupted teeth. All children were from four day nurseries located in Poznan. The study included the dental examination to select individuals to the research and oral swab collection for molecular evaluation. Seven selected SNPs markers of the ENAM gene were genotyped, five using TaqMan probe assay (rs2609428, rs7671281, rs36064169, rs3796704, and rs12640848) and two by Sanger sequencing (rs144929717 and rs139228330). Statistically significant higher prevalence of the alternative G allele and the alternative GG homozygote in the control group in comparison with the caries group in SNP rs12640848 was observed, respectively, p = 0.0062 and 0.0010. Although the prevalence of the AG heterozygote was higher for the caries subjects in comparison with controls (OR = 2.9), and the result was statistically significant (p = 0.0010), the overall prevalence of the G allele for this SNP was significantly higher in control group (OR = 2.3; p = 0.0062). The study revealed the strong association between rs12640848 marker of ENAM gene and caries susceptibility in primary teeth in children from Poznan. The presence of SNPs in the ENAM gene may be important as suspected predictive factor of dental caries occurrence in children.

    The article presents the results of examination and treatment of patients with initial caries (K02.0), infected with herpes virus. Technologies and methods used by most dentists are not sensitive enough to detect caries at early stages, while the remineralizing therapy can be very effective. The method of laser fluorescence spectroscopy with DIAGNOdent pen device (KaVo) was used for diagnostic of dental caries at early stages. Treatment was carried out with HealOzon device (KaVo), which is used in oral medicine to produce ozone.

    Full Text Available The prevalence of dental caries in 6, 9, 12 and 15-year-old school children of Chandigarh, selected on a randomized basis was evaluated using Moller′s criteria (1966 and correlated with the various risk factors. The mean deft was found to be 4.0 ± 3.6 in 6 year old and 4.61 ± 3.14 in 9 year old, whereas the mean DMFT in 12 and 15 year old was found to be 3.03 ± 2.52 and 3.82 ± 2.85 respectively. The high prevalence of dental caries in these children was attributed to the lack of use of fluoride toothpaste (80% children, lack of knowledge about etiology of dental caries (98% and frequency of sugar exposures up to more than five times per day (30%.

  15. DENTAL CARIES LEADING TO PREMATURE LOSS OF BABY TEETH- IMPLICATIONS AND MANAGEMENT

    Full Text Available Dental caries is a destructive process causing decalcification of the tooth enamel and leading to continued destruction of enamel and dentin, and cavitation of the tooth. Dental caries can occur soon after eruption of the primary teeth, starting at 6 months of age. Primary teeth are present for a reason. One key reason is that they save space for the permanent tooth, which will erupt into its position when the deciduous / primary tooth is lost normally. If a primary tooth (baby or milk tooth, has to be removed early due to say, an abscess which is mostly a result of dental caries, a space maintainer may be recommended to save the space. If the space is not preserved, the other teeth may drift causing difficult to treat crowding and orthodontic problems. These "spacers" are placed temporarily, and are not permanent. They are removed when the new tooth (usually a bicuspid erupts or the abutment teeth get loose.

  16. Dental caries and periodontal disease (prevention and control methods).

    There is a compelling need to apply preventive programs in both private and community practice of dentistry. This is to maintain improvements in oral health in developed and industrialized countries, and to stem increases in oral diseases in underserved and developing ones. At the outset, the terms prevention and control must be understood. The former is considered to mean a procedure or course of action that prevents the onset of disease, whereas the latter, implies reversing or stabilizing disease conditions. To be more precise, prevention will refer to the pre-pathologic or pre-clinical stage encompassing the promotive and specific protection levels--primary prevention stage. On the other hand, control will encompass early diagnosis and prompt treatment, disability limitation and rehabilitation levels-termed also collectively, as pathologic, clinical and final stages, or secondary and tertiary prevention. Community-based programs are usually structured to compliment therapeutic interventions of oral diseases, as well as prevention. In this era, and towards the next millennium, preventive and control programs are given high priorities in order to minimize the need for curative, restorative and therapeutic management of oral diseases. This review of the literature will give emphasis on established methods and programs for the prevention and control of the two most common oral diseases, dental caries and periodontal disease. The problems, background, and oral health objectives for the year 2000 as proposed by the World Health Organization (WHO) and the Federation Dentaire Internationale (FDI), as well as the recent advances in oral health relative to these diseases will be discussed. Finally, to better improve the efficacy of existing prevention and control methods, research needs and areas of concern relative to these diseases will be given consideration.

    Objectives A number of articles have addressed gender differences in the productivity of dentists, but little is known about differences in practice patterns for caries management. This study compared the use of a comprehensive range of specific diagnostic methods, preventive agents, and restorative decision making for caries management between male and female dentists who were members of The Dental Practice-Based Research Network(DPBRN). Methods This study surveyed general dentists who were members of DPBRN and who practiced within the United States. The survey asked about dentist, practice, and patient characteristics, as well as prevention, assessment, and treatment of dental caries. Differences in years since dental school graduation, practice model, full/part-time status, and practice owner/employee were adjusted in the statistical models, before making conclusions about gender differences. Results Three hundred ninety-three male (84%) and seventy-three female (16%) dentists participated. Female dentists recommended at-home fluoride to a significantly larger proportion of their patients, whereas males had a preference for using in-office fluoride treatments with pediatric patients. Female dentists also choose to restore interproximal lesions at a significantly later stage of development, preferring to use preventive therapy more often at earlier stages of dental caries. There were few differences in diagnostic methods, time spent on or charges for restorative dentistry, and busyness of their practices. Conclusion DPBRN female dentists differ from their male counterparts in some aspects of the prevention, assessment, and treatment of dental caries, even with significant covariates taken into account. Practice patterns of female dentists suggest a greater caries preventive treatment philosophy. PMID:21454850

    There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥ 16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses. © 2014 Eur J Oral Sci.

    Silver diamine fluoride (SDF) treatment has been identified as a potential solution to address the dental public health issues of untreated dental caries and insufficient access to care. The current study assessed the effectiveness of 38 percent SDF in arresting active dental caries lesions and in reducing or preventing associated dental pain and infections in young, at-risk children. We enrolled 32 children aged 2-5 years with 118 active caries lesions in primary teeth from a community dental clinic in Oregon. After baseline examinations, carious lesions were treated with 1-2 applications of 38 percent SDF. Children were re-evaluated at 3-week and 3-month recalls to assess color and consistency changes in lesions (soft/hard). Parents were interviewed regarding symptoms of pain or infection and were surveyed regarding subjective feelings about SDF. Of 102 lesions (16 excluded from analyses), 100 were found to be arrested at first recall and all at second recall. The duration of SDF application was not associated with arrest of decay (P = 0.68). No incidence of pain or infection of an SDF-treated tooth was recorded. Parental impression of ease of application, taste, and esthetics was favorable. Our results suggested SDF was effective in arresting active caries lesions in primary teeth in young children and was well accepted by parents. SDF offers an easy and highly efficient nonsurgical alternative treatment to traditional restorative dental treatment in young children, and it has great potential to aid the dental public health community to address dental caries in at-risk populations. © 2017 American Association of Public Health Dentistry.

    Colonization resistance is one of local immunity mechanisms determined by a combination of factors that inhibit the adhesion and growth of mucous membrane bacteria. We examined patients with different levels of caries intensity assessing oral mucosa colonization resistance by our own method. Caries development resulted in changes of colonization resistance with the increased rate of inhibition of the oral mucosa colonization resistance barrier.

    The aim of this study was to examine the relationship between differences in dental attendance and oral hygiene patterns and dental caries and periodontal treatment needs. 1469 young people, aged 7, 12 and 15-19 years, and representing the urban (60%) and rural (40%) population from Spain were evaluated. Dental caries and periodontal treatment needs were registered according to the index D.M.F.T. and C.P.I.T.N., following the criteria of W.H.O. Regular dental attendance was observed in 16.6% of subjects examined, and only 9.4 saw a dentist regularly for dental prophylaxis. Statistical analyses showed that while the more frequent the dental visits, the lower the rate of caries, and periodontal treatment needs, the higher, however, the average number of fillings and the D.M.F.T. scores. These individuals had the higher number of functioning teeth, restored or sound, but they also had the disadvantage of having higher levels of disease experience. By the other way the individuals who saw the dentist regularly for dental prophylaxis presented the lower caries rate and periodontal treatment needs, the fewer tooth loss, and also an important reduction in the D.M.F.T. scores. Similar observations had been made in the individuals who brush their teeth frequently or with a correct technique. The results suggested that while frequent dental visits do not apparently help to prevent the onset of further dental disease, we can achieve this goal with regular preventive oriented dental therapy.

  5. Antibacterial Peptides: Opportunities for the Prevention and Treatment of Dental Caries.

    Science.gov (United States)

    Pepperney, Adam; Chikindas, Michael L

    2011-06-01

    Dental caries is a multifactorial disease that is a growing and costly global health concern. The onset of disease is a consequence of an ecological imbalance within the dental plaque biofilm that favors specific acidogenic and aciduric caries pathogens, namely Streptococcus mutans and Streptococcus sobrinus. It is now recognized by the scientific and medical community that it is neither possible nor desirable to totally eliminate dental plaque. Conversely, the chemical biocides most commonly used for caries prevention and treatment indiscriminately attack all plaque microorganisms. These treatments also suffer from other drawbacks such as bad taste, irritability, and staining. Furthermore, the public demand for safe and natural personal hygiene products continues to rise. Therefore, there are opportunities that exist to develop new strategies for the treatment of this disease. As an alternative to conventional antibiotics, antibacterial peptides have been explored greatly over the last three decades for many different therapeutic uses. There are currently tens of hundreds of antibacterial peptides characterized across the evolutionary spectrum, and among these, many demonstrate physical and/or biological properties that may be suitable for a more targeted approach to the selective control or elimination of putative caries pathogens. Additionally, many peptides, such as nisin, are odorless, colorless, and tasteless and do not cause irritation or staining. This review focuses on antibacterial peptides for their potential role in the treatment and prevention of dental caries and suggests candidates that need to be explored further. Practical considerations for the development of antibacterial peptides as oral treatments are also discussed.

    Anaemia caused by iron deficiency and dental caries are still among the most prevalent diseases in some developing countries. Anaemia can be prevented by iron fortification of food. Previous studies demonstrated that iron-sucrose, which has been used for prevention of anaemia, reduces the incidence of caries in rats. The aim of the present study was to compare the influence of ferrous sulphate and ferric glycerophosphate co-crystallized with sucrose on the incidence of dental caries in rats. Forty-eight desalivated rats were caged in a programmed feeder and received their essential nutrition by gavage. The animals were fed 17 meals per day at hourly intervals of 88 parts/10(6) Fe++ or Fe co-crystallized with sucrose. Plain sucrose and calcium glycerophosphate with sucrose were used as control groups. Both ferric- and ferrous-sucrose meals reduced the incidence of smooth-surface and sulcal caries in rats. Stain formation, organic acid production and acidogenic activity of dental plaque in animals receiving iron-sucrose meals were also investigated. Ferric glycerophosphate did not induce extrinsic staining on the tooth surface. The concentration of organic acids did not differ significantly among the groups. The acidogenic activity of plaque in animals receiving either of the iron-sucrose meals tended to be lower than that of the control groups. The possibility that iron-sucrose might reduce the prevalence of two major public health problems, dental caries and anaemia, makes this preventive approach extremely attractive for additional investigation.

    The objective of this study was to determine the responsiveness of oral health-related quality of life (OHRQoL) (oral health impact profile [OHIP] and oral impact on daily performance [OIDP]) and health-related quality of life (HRQoL) (World Health Organization quality of life scale, brief [WHOQOL-BREF]) in dental caries restoration treatment. The study also aimed to assess the influence of treatment on the responsiveness of patients' quality of life (QoL). A total of 126 patients (aged 16-40 years) received dental caries restoration treatment with a 2-week follow-up and pre- and posttreatment interviews by questionnaire. Patients were assessed for their perceptions of OHRQoL and HRQoL by using the OHIP, OIDP, and WHOQOL-BREF measures. The responsiveness of all outcome measurements was assessed by effect size (ES). Stepwise multiple regression analysis was used to examine the association with the responsiveness of all outcome measurements. Significant differences were found between OIDP (ES = 0.39), OHIP (ES = 0.54), and WHOQOL-BREF (ES = 0.13) with regard to pretreatment and posttreatment (p-values: caries status at baseline were significantly associated with responsiveness by all measurements. This study suggests that dental caries treatment moderately improves OHRQoL, but is less related to HRQoL. Furthermore, the number of dental caries and restoration are important factors affecting the improvement of patients' perceived OHRQoL.

    Down syndrome (DS) is the most common genetic disorder in humans, but its incidence in monozygotic twins is extremely rare. The aim of this study was to determine the factors associated with dental caries in a pair of monozygotic twin girls with DS, where one had caries experience and the other did not. Clinical examination, salivary Streptococcus mutans (S. mutans) levels and their genotypic diversity, the biochemical composition of the dental biofilm, the frequency of sucrose consumption, and toothbrushing habits were assessed from the twin girls. Twin with caries experience showed higher levels of S. mutans in the saliva and lower concentrations of calcium, phosphate, and fluoride and higher concentrations of extracellular polysaccharides in the biofilm compared to her sister. Genotypic diversity of S. mutans was also higher in the twin with caries experience. Dental biofilm composition showed different patterns of cariogenicity between the two sisters, which may also by itself explain the difference in the dental caries between them. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

    Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

    To investigate the status of dental caries of deciduous teeth among preschool children in Shenyang city. According to the criteria recommended by the World Health Organization and The Second National Oral Health Investigation, the deciduous caries of 5375 preschool children aged from 3 to 6 years were clinically examined. The mean dmft and the prevalence of dental caries for each age group were calculated. The results were analyzed using SPSS11.0 software package for t test (to compare the difference between the two sample groups), one way ANOVA (to compare the differences among three and more sample groups) and chi2 test (to compare the rate of each group). The prevalence of dental caries was 71.29%. The mean dmft score was 3.88. The prevalence of dental caries and mean dmft increased gradually as the children were growing up (P caries of the upper teeth was significantly more common than that of the lower teeth (P caries were minor in degree of severity, and mostly lie in the occlusal and proximal surface. The filling rate was 10.82%.As the age increase, the filling rate increased, too. Deciduous dental caries of preschool children was an important problem in Shenyang city, and the filling rate was very low. Necessary methods for early prevention of dental caries must be taken into consideration.

    Teeth are an interesting material for the study of ancient populations. The aim of our study was to determine the prevalence and distribution of caries in a medieval sample of paired maxillas in a rural population in Southwest France and to compare men and women. Our sample included 58 adults, 29 men and 29 women, with dentate maxillas in good state of conservation, for a total of 1,395 teeth out of a possible 1,846 (75%). The number of caries and their localization were noted. The frequency of antemortem missing teeth was 8.67%. The prevalence of caries was 17.46% and the most frequent caries were occlusal and proximal. Second and third molars were the most frequently affected maxillary and mandibular teeth. Caries on maxillary teeth were statistically more frequent than on mandibular teeth (p0.05). Our study showed that the frequency and the distribution of dental caries in this medieval population from southwest France were comparable to those of other European populations from the same period. The low level of caries was probably due to attrition and noncariogenic food. Differences between men and women were not significant, even though our results suggest that men were much more concerned by caries than women, especially for posterior teeth. A different diet may be the reason for this difference.

No such information was available for pre-school children in Mbeya city. To determine dental caries status and associated factors in 2 to 4-year-old children in Mbeya city. A cross sectional study was conducted among 525 children aged 2-4 years and their parents/caregivers. Caries was assessed using caries assessment spectrum and treatment index, oral hygiene by visual inspection for visible plaque on index teeth, and dietary and oral hygiene habits by a questionnaire. Kappa statistics was used to test reliability of study instruments, χ 2 -test and logistic regression was employed for studying associations. Caries free children for dmft1, dmft2 and dmft3 were 79.8%, 83.8% and 94.7% and caries experience was 0.49 (1.23), 0.4 (1.14) and 0.10 (0.53) respectively. Older age [(OR =2.722 (1.617-4.582) p =caries. Prolonged breastfeeding for more than 1 year and breastfeeding at night had no association with dental caries. The prevalence of dental caries was very low. Older age and frequent consumption of factory made sugary foods at age 1-2 years were associated with higher odds of developing dental caries. Prolonged breasfeeding and breastfeeding at night had no association with dental caries. Prevention of dental caries should be instituted as soon as primary teeth start erupting, especially through discouraging consumption of factory made sugary foods/snacks.

    To investigate ethnic-specific deprivation gradients in early childhood dental caries experience considering different domains of deprivation. We used cross-sectional near whole population-level data on 318 321 four-year-olds attending the "B4 School check," a national health and development check in New Zealand, across 6 fiscal years (2010/2011 to 2015/2016). The "lift the lip" screening tool was used to estimate experience of any caries and severe caries. We investigated deprivation gradients using the Index of Multiple Deprivation (IMD), which measures seven domains of deprivation across 5958 geographical areas ("data zones"). Ethnicity was categorized into five groups: (i) Māori, (ii) Pacific, (iii) Asian, (iv) Middle Eastern, Latin American and African (MELAA) and (v) European & Other (combined). We used a random intercepts model to estimate mutually adjusted associations between deprivation, ethnicity, age, fiscal year, and evidence of any dental caries experience. Reports of any caries experience decreased from 15.8% (95% CI: 15.7; 15.9%) to 14.7% 95% CI: 14.4; 14.8%), while reports of severe caries experience increased from 3.0% (95% CI: 3.0; 3.1%) to 4.4% (95% CI: 4.3; 4.5%) from 2010/2011 to 2015/2016. This varied by ethnicity with larger increases in severe caries for Pacific children from 7.1% (95% CI: 6.8; 7.4%) to 14.1% (95% CI: 13.7; 14.5%). There were deprivation gradients in dental caries experience with considerable variation by ethnicity and by domain of deprivation. The association between deprivation and dental caries experience was weakest for Asian children and was most pronounced for Pacific and Māori children.

    The objective of this study was to investigate the influence of caregiver education level on children's dental caries mediated by both caregiver and child oral health behaviors. Participants were 423 low-income African American kindergarteners and their caregivers who were part of a school-based randomized clinical trial. Path analysis tested the hypothesis that caregiver education level affected untreated dental caries and cumulative overall caries experience (decayed or filled teeth) through the mediating influence of frequency of dental visits, use of routine care, and frequency of toothbrushing for both caregiver and child. The results supported the hypothesis: Caregivers who completed high school were 1.76 times more likely to visit dentists themselves compared with those who did not complete high school (e0.56=1.76, 95%CI: 1.03-2.99), which in turn was associated with 5.78 times greater odds of dental visits among their children (e1.76=5.78, 95%CI: 3.53-9.48). Children's dental visits, subsequently, were associated with 26% fewer untreated decayed teeth compared with children without dental visits (e-0.31=0.74, 95%CI: 0.60-0.91). However, this path was not present in the model with overall caries experience. Additionally, caregiver education level was directly associated with 34% less untreated decayed teeth (e-0.42=0.66, 95% CI: 0.54-0.79) and 28% less decayed or filled teeth (e-0.32=0.72, 95%CI: 0.60-0.88) among the children. This study overcomes important conceptual and analytic limitations in the existing literature. The findings confirm the role of caregiver education in child dental caries and indicate that caregiver's behavioral factors are important mediators of child oral health. PMID:25661111

    Data on epidemiology of dental caries of adults in rural India appear to be sparse. The purpose of the study was to assess the oral health status and dental treatment needs of a rural Indian population. The study population consisted of 189 volunteer subjects with a mean age of 34.9 ± 14.2 years and 54% males. Decayed, missing due to caries and filled teeth (DMFT) and tooth surfaces (DMFS) assessed the dental caries experience. Structured interviews collected data on perception of health including oral health, oral hygiene practices and snacking habits. While only 38.1% perceived themselves to be in good or very good dental health, nearly 85% felt the same about general health. The most common sugar exposure was sweetened tea; 75% consumed the beverage at least once a day. More than 80% of the subjects had untreated caries with mean DMFT and DMFS scores of 5.1 ± 3.9 and 13.8 ± 17.8, which lacked any gender differences. Dental treatment needs ranged from 16.9% two-surface fillings to 60.8% one-surface fillings; 23.8% crowns or bridges and 37.6% extractions. Those who perceived themselves to be in better oral health had significantly lower DMFT (4.0 ± 3.2 vs 5.9 ± 4.1) and DMFS (8.4 ± 11.7 vs 17.1 ± 20.0) scores (p dental caries as well as dental treatment needs among the study participants.

    The aim of this study was to determine the association between obesity and caries by utilizing the data of a cohort of preschool children aged 4-5 years. Data were obtained from a cohort of 1,160 children. Dental caries detection was performed according to the World Health Organization criteria. The caries index was measured as the number of decayed (d), extracted (e), and filled (f) teeth (t) (deft), or surfaces (defs). The body mass index (BMI) in units of kg/m2 was determined, and children were categorized according to age- and gender-specific criteria as normal weight (5th-85th percentile), at-risk overweight (> or = 85th- or = 95th percentile). Odds ratios were determined for at-risk overweight and overweight children using logistic regression. The prevalence of dental caries was 17.9 percent. A slightly higher percentage of dental caries was found in boys (19.6 percent) than in girls (16.4 percent). From the total sample, the mean BMI was 17.10 +/- 3.83. Approximately 53.7 percent of children were classified as normal weight, 14.2 percent as at-risk overweight, and 32.1 percent as overweight. At-risk overweight children were higher among girls (17.1 percent) than among boys (11.3 percent). When adjusted for covariates, the logistic regression model showed that there was a significant association between at-risk overweight children (P caries in the primary dentition. Mean (SD) deft value of the sample was 1.08 (2.34), while the corresponding defs value was 1.43 (3.29). Obesity appears to be associated with dental caries in the primary dentition of preschool Mexican children.

    Dental caries is the most common chronic disease of childhood that interferes with normal nutrition intake, speech, and daily routine activities. Dental caries is a lifetime disease, and the highest priority risk group is school children. To assess the prevalence of dental caries and treatment needs among school going children of Chandigarh. A cross-sectional study was done among school going children of Chandigarh in the age group of 3-17 years. The subjects were selected from four randomly selected schools. All the children from the selected schools were examined. A total of 4493 subjects formed the sample size. Dentition status was assessed using dft index by Gruebbel for primary dentition and DMFT index by Klein, Palmer, Knutson for permanent dentition, respectively. Chi-square test was used to find an association between the study variables. Independent t-test and one-way ANOVA were used to compare the mean difference. Among the 4493 study subjects, caries prevalence was found to be 47.3%. Mean dft and DMFT score of the population was 1.06 ± 1.995 and 0.41 ± 1.022, respectively. When analyzing the treatment needs among various age groups 42.6% of the study subjects required oral prophylaxis and 45% required restorative procedures. Based on the findings, it can be concluded that high prevalence of caries was found in primary dentition than permanent dentition and most of the decayed teeth were untreated. This study emphasize the need for treating dental caries at its earliest possible stage and parents should be made aware of caries preventive measures for their children.

    Oral diseases are considered as major public health problem. Dental caries restricts the school activities and are the dominant cause of dental morbidity. The aims of this survey were to determine prevalence of dental caries among pupils of Dakar and to study their food habits and oral hygiene. A descriptive transversal study was conducted from February 15th to May 07th, 2011 with respect of WHO directives (protocol of 1997) readjusted to Senegalese context. Our results showed a prevalence of 41.8%; a mean DMF index of 0.644; a proportion of teeth decayed of 65%, 32.2% for missing teeth and 2.7% of filled teeth. The multivariate logistic regression analysis showed that snacking, consumption of sweetened drinks far from meals and brushing teeth before the meals were significantly linked to the presence of dental caries. These results showed that the state of oral health and the prevention level of dental caries among these children were not so good. A new orientation of oral health policy based on messages regarding the main etiologic factors is imperative.

    Full Text Available Lesion of hard dental tissue with caries process and lesions not connected with caries present overwhelming majority of dental diseases. Causes leading to damage of enamel integrity and dentin with progressing demineralization are known; they allow to choose justified method of primary prophylaxis. Along with it, etiology and pathogenesis of enamel lesions with demineralization signs remains unexplored. Epidemiologic study of prevalence, incidence and severity of lesion of hard dental tissues in 330 pupils, who constantly live on endemic iodine-defficient territory, of three zones – mountain zone, foothill and valley. For comparison, schoolchildren migrated to this territory 2-3 years after birth, and children – residents of favorable as for iodine level in drinking water were examined, 30 children in each group. It was established, that overwhelming number of schoolchildren of endemic zone suffer from endemic goiter of various severity, which sufficiently impacts on protein-mineral ratio of the organism, bone skeleton and teeth including. It was also established, that residents of three various levels of iodine consumption are prone to development of multiple dental caries and systemic enamel hypoplasia. Children, residents of mountain zone suffer the most, with simultaneous lesion of thyroid gland. The role of endemic goiter in systemic dental enamel hypoplasia and multiple caries, which changes protein matrix, negatively impacts on odontogenesis and mineralization degree is underlined.

    Objectives: To compare two surveys across seven states for the prevalence of dental caries among Mexican schoolchildren. Study Design: Analysis of two cross-sectional surveys: Schoolchildren from 6 to 10 years of age were examined in the 1988–1989 survey and 6- to 10-year-old and 12-year-old students were included in the 1998–2001 survey. The baseline data of seven states were available for analysis. Representative probability samples were conducted statewide in both surveys. The World Health Organization (WHO) method was used to obtain the dental caries index (dmft, DMFT). At present, additional and more recent epidemiological data representative statewide in Mexico are unavailable. Results: The participants were 9798 schoolchildren in the 1988–1989 survey and 16882 schoolchildren in the 1998–2001 survey. The prevalence of caries in children ages 6 to 10 years was 86,6% in the first survey and 65,5% in the second survey, showing a 24,4% reduction. The primary teeth index in the first survey was dmft = 3,86 (IC95% 3,68 4,04) and in permanent teeth, it was DMFT = 1,03 (IC95% 0,95 1,11). In the second survey, the comparable values were dmft = 2,36 (IC95% 2,20 2,52) and DMFT = 0,35 (IC95% 0,29 0,40), corresponding to a reduction of 38,89% and 66,02% in the primary and permanent dentition, respectively. Treatment needs remain high: In the second survey, as 92,75% of the index DMFT was conformed as decayed teeth. Conclusion: Overall, we detected a downward trend in the dental caries indices, particularly in the permanent dentition. The increase in the availability of fluoride likely contributed to the observed decline in dental caries. Key words:Schoolchildren, dental caries, treatment needs, salt fluoridation, Mexico.

    Body mass index (BMI) is an index that measures height for weight, which is commonly used to categorize underweight, overweight, and obese individuals. Deviation from normal weight results from an imbalance between caloric consumption and energy expenditure. Childhood obesity and childhood dental caries are coincidental in many populations, probably due to common confounding risk factors, such as intake frequency, cariogenic diet, and poor oral hygiene. So the aim of the present study was to assess the BMI status and to corelate between dental caries and BMI among the Anganwadi children of Belgaum city, Karnataka, India. Four hundred and thirty three children from 20 Anganwadi's belonging to the age group of 2 to 6 years of both sexes were measured for BMI and dental caries status. The caries index was measured as the number of decayed (d) and filled (f) teeth (t) (dft). The BMI in units of kg/m 2 was determined and children were categorized according to age-and gender-specific criteria as underweight (95th percentile). The data were subjected to statistical analysis using Student's t-test, analysis of variance (ANOVA), and Karl Pearson's correlation coefficient test with the help of Statistical Package for the Social Sciences (SPSS) version 18.0. The proportion of subjects in Centre for Disease Control (CDC) weight categories was: 5% underweight, 79% normal, 9% under the risk for overweight, and 6% overweight. A significant association was found between children with normal BMI and those who were underweight, overweight, and under the risk for overweight. Children with overweight/obese or underweight/malnourished children had higher decayed and filled surfaces compared to children with normal weight. Nutritional status has a profound effect on dental caries. Both underweight/malnutrition and overweight/ obesity have significant adverse implications for health. Childhood obesity and childhood dental caries are coincidental in many populations.

    Full Text Available INTRODUCTION: Dental caries and nutritional status in children in preschool age are serious public health problems, with multifactorial etiology, with diet as a common risk factor. OBJECTIVE: This cross-sectional study assessed the relationship between dental caries and nutritional status of preschool children attending public schools in a city in the State of Sao Paulo. MATERIAL AND METHOD: The study population was comprised of 3-5 year-old preschool children (n = 229 attending public schools, in which dmft (decay, missing, filled, teeth was used for dental caries assessment and Body Mass Index (BMI was used for nutritional status in accordance with the recommendations of the World Health Organization. Statistical analysis was performed in a descriptive way through absolute and relative frequencies and Spearman Correlation test and Kruskal Wallis (P<0.05. RESULT: A dmft of 1.65 (2.87 and a SiC index (Significant Caries Index of 4.88 (3.20 have been found, indicating polarization of dental caries. It was observed that 66.81% of children presented with nutritional status within the normal range and children with malnutrition had a mean dmft of 4.0 (3.66, which is two times higher than the other categories of nutritional status. No statistically significant correlation has been found by correlating dmft and components with Body Mass Index. CONCLUSION: This research did not identify a significant correlation between the occurrence of dental caries and nutritional status of preschool children, researches should be conducted to elucidate this relationship.

    Few studies have assessed the effect of breastfeeding, bottle feeding, and sugar consumption on children's dental caries. We investigated whether the duration of breastfeeding is a risk factor for dental caries in the primary dentition, independently of sugar consumption. An oral health study ( n = 1303) nested in a birth cohort study was carried out in southern Brazil. The average number of decayed, missing, and filled primary tooth surfaces (dmfs) and severe early childhood caries (S-ECC: dmfs ≥6) were investigated at age 5 years. Breastfeeding was the main exposure collected at birth and at 3, 12, and 24 months of age. Data on sugar consumption were collected at 24, 48, and 60 months of age. Marginal structural modeling was used to estimate the controlled direct effect of breastfeeding (0-12, 13-23, and ≥24 months) on dmfs and on S-ECC. The prevalence of S-ECC was 23.9%. The mean number of dmfs was 4.05. Children who were breastfed for ≥24 months had a higher number of dmfs (mean ratio: 1.9; 95% confidence interval: 1.5-2.4) and a 2.4 times higher risk of having S-ECC (risk ratio: 2.4; 95% confidence interval: 1.7-3.3) than those who were breastfed up to 12 months of age. Breastfeeding between 13 and 23 months had no effect on dental caries. Prolonged breastfeeding increases the risk of having dental caries. Preventive interventions for dental caries should be established as early as possible because breastfeeding is beneficial for children's health. Mechanisms underlying this process should be investigated more deeply. Copyright © 2017 by the American Academy of Pediatrics.

    Full Text Available Context : India has been the focus of many health surveys among normal, physically, and mentally handicapped children. However, the data, concerning oral health conditions of socially handicapped children living in orphanages, are scanty. Aims: To study the effect of parental inadequacy, environmental deprivation, and emotional disturbances on dental caries through intelligence quotient (IQ and self-concept in orphan children and also to co-relate dental caries with different levels of IQ and self-concept. Settings and Design: The study was carried out amongst socially handicapped children living in orphanages. Patients and Methods: 100 children in the age group of 10-14 years from orphanages were selected. Malin′s Intelligence Scale for Indian Children (MISIC was used to assess the intelligence quotient; self-concept questionnaire to assess self-concept of the child and recording of dental caries status of children was done as per WHO Index (1997. StatisticaL Analysis Used : To assess the relationship of dental caries with IQ, student′s unpaired t-test was used and; to find the relationship between self-concept and dental caries, Karl-Pearson′s coefficient of co-relation was applied. Results: the children in orphanages had a lower IQ and high caries experience but had an above average self-concept. There was also no co-relation between dental caries and self-concept. Conclusions: Orphan children, being socially handicapped, are at an increased risk for dental caries due to a lower IQ level, parental deprivation, and institutionalization. Moreover, lack of co-relation between dental caries and self-concept could be explained by the fact that dental caries is a lifelong process whereas different dimensions of self-concept are in a state of constant flux.

    Full Text Available Purpose: The aim of the presented study was to determine the incidence of secondary root caries lesions in patients referred for treatment in the Faculty of Dental Medicine – Sofia. Material/Methods: The subjects who took part in the study were patients referred for treatment of caries lesions in the Faculty of Dental Medicine, Sofia. They were interviewed for smoking, presence of systematic diseases and medications and debris and plaque were removed from natural teeth prior to examination. Dental examination was carried out with a dental mirror and a probe. Decayed, missed and filled teeth (DMFT were recorded. Root caries lesions, restorations of those lesions and secondary caries lesions were recorded separately. Results: A total number of 603 patients were examined. The frequency of appearance of root caries in the investigated population was 33.5% (202 patients. The whole number of root caries lesions was 857. Three hundred forty three (41.4% of those lesions were restored. Presence of secondary caries lesions was observed in 138 cases (39.1%. Conclusions: Based on the data obtained from the presented study it may be concluded that most of the root caries lesions remain untreated (58.8%. Secondary carious was diagnosed in 39.1% of the root caries restorations. The patients with secondary caries lesions presented with higher incidence of concomitant diseases and lower incidence of smoking.

    Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH. Totally, 76 female students within the age group of 18-23 years were clinically examined, and their decayed, missing, filled teeth (DMFT) score and oral hygiene index-simplified were recorded. Based on their DMFT score, they were divided into following three groups; group I (n = 16, DMFT score = 0), group II (n = 30, DMFT score Dermatoglyphic pattern distribution in caries-free group showed more ulnar loops than high caries group (group III) while high caries group showed more whorl patterns. Presence of whorl with double loop, whorl within a loop was associated with high DMFT score. The total finger ridge count was lower in caries group. The mean salivary pH was higher in caries-free group than high caries group. Thus, we conclude that dermatoglyphic patterns may be potential diagnostic tool for detecting patients prone to develop dental caries.

    We have previously reported that dental caries progress in spontaneously and chemically induced diabetic rodent models. The aim of this study was to clarify the relationship between hyperglycemia and dental caries by evaluating the preventive effect of glycemic control with insulin on the progression of the lesions in diabetic rats. Male WBN/KobSlc rats aged 15 weeks were divided into groups of spontaneously diabetic rats (intact group), spontaneously diabetic rats with insulin treatment (INS group), alloxan-induced prolonged diabetic rats (AL group), and alloxan-induced prolonged diabetic rats with insulin treatment (AL + INS group). The animals were killed at 90 weeks of age, and their oral tissue was examined. Dental caries and periodontitis were frequently detected in the intact group, and the lesions were enhanced in the AL group (in which there was an increased duration of diabetes). Meanwhile, glycemic control with insulin reduced the incidence and severity of dental caries and periodontitis in the INS group, and the effects became more pronounced in the AL + INS group. In conclusion, glycemic control by insulin prevented the progression of dental caries and caries-related periodontitis in the diabetic rats.

    Dental caries and enamel defects (DDE) are prevalent amongst children. The presence of DDE, especially enamel hypomineralization, may increase caries experience. The reported prevalence of hypomineralized second primary molars (HSPM) is 2.7-21.8%, although the occurrence in Australian children remains unknown. These HSPM represent a potential predictive factor for molar-incisor hypomineralization (MIH). In total, 623 children aged 3-5 years from 30 randomly selected kindergartens participated. The HSPM were recorded using an index combining the European Academy of Paediatric Dentistry MIH Judgment Criteria and modified DDE Index. Caries was recorded using International Caries Detection and Assessment System criteria. In total, 144 HSPM were observed in 88 of the 623 (14.1%) children, a tooth-level prevalence of 5.8%. The prevalence of dentinal carious lesions was 13.2%, and caries prevalence (d 2-6 mft > 0) was 36.4%. Cavitated carious lesions affected 30.7% of HSPM. The relationship between an increase in HSPM lesion extent and increasing number of HSPM per child was statistically significant. A positive association between HSPM severity and extent at tooth level existed (P < 0.05). There was a positive relationship between the extent of HSPM and carious lesion severity (P < 0.05). In this population, children with HSPM did not have overall greater caries experience. © 2017 Australian Dental Association.

    This study aimed to determine the prevalence of molar incisor hypomineralization (MIH) in Thai children and evaluate the association between MIH and dental caries in the permanent dentition. A cross-sectional study was conducted among six- to seven-year-old participants of a birth cohort study in Khon Kaen, Thailand. MIH was examined by one calibrated dentist using European Academy of Pediatric Dentistry criteria. The association between MIH and caries was determined by logistic regression at subject level, and generalized estimating equations at tooth level. Of 484 children who had at least one erupted permanent first molar, the prevalence of MIH was 20 percent, with no difference between genders. Children with MIH had increased odds of having caries in the permanent dentition compared to those without MIH (odds ratio [OR] equals 4.6; 95 percent confidence interval [CI] equals 2.7 to 7.9). MIH molars had approximately 10 times higher odds of developing caries than non-MIH counterparts (OR equals 9.9; 95 percent CI equals 5.7 to 16.9). Caries risk was higher in the upper molars than in the lower molars. Molar incisor hypomineralization is common and associated with increased risk for dental caries among this group of Thai children.

    Vitamin D may prevent dental caries. To date, no attempts have been made to examine the correlation between the incidence of caries and the concentrations of vitamin D in children with pituitary growth hormone deficiency.The study observed patients of the Department of Endocrinology and Diabetology of the University Paediatric Hospital of the Medical University of Lublin treated with human recombinant growth hormone for pituitary growth hormone deficiency (GHD). The study was conducted between October 2014 and June 2015. The study group consisted of 121 children and adolescents (6-17 years old), including 56 children from rural areas and 65 children from urban areas. The study group was stratified by area of residence.In our study, the increase in vitamin D3 [25(OH)D] levels reduced the D component by 0.66 per each 10 ng/mL of vitamin D3 concentration. The percentage of children with active caries in rural areas is 91.07% (n = 51), which is significantly higher than the percentage of children with active caries in urban areas (81.54%, n = 53).To date, information regarding the potential possibility of reducing the incidence of dental caries by means of increasing the levels of vitamin D was sidelined by paediatricians and dentists alike. Therefore, this aspect of caries prevention should be highlighted.

The study used data of 7,280 five-year-old children participating in the 2010 Brazilian Oral Health Survey (SBBrasil 2010 Project). Children were clinically examined and their parents or carers were interviewed at their homes. The outcome was the prevalence of the oral impacts on daily performance, and the explanatory variable was dental pain in the last six months. Other independent variables were children's gender and skin color/race, family income, household overcrowding, and caries experience (dmft). Rao-Scott test and Poisson regression for complex samples were carried out. The prevalence of impacts on daily performances was 26.1% (95%CI 22.3-30.2). Significant associations were found between the outcome and pain, caries experience, and sociodemographic variables. After adjusting for the independent variables, only pain and caries remained significant. Impacts on daily performances were more frequent among children with pain (PR = 1.14, 95%CI 1.06-1.23) compared to those without pain. Children with low dmft (PR = 1.90, 95%CI 1.39-2.60) and those with high dmft (PR = 3.53, 95%CI 2.78-4.49) had a higher prevalence of impact than those with no caries experience. Dental pain and caries had strong negative impacts on the five-year-old children's daily performances regardless of their demographic and socioeconomic characteristics.

    The purpose of this study was to assess Maryland physicians' knowledge and understanding of dental caries etiology and prevention, opinions related to prevention effectiveness, and their prevention practices. In 2010, a 30-item, self-administered survey questionnaire was mailed to a random sample of 1,472 Maryland family physicians and pediatricians, with 294 surveys being returned and usable, yielding a 20 percent return rate. Statistical analyses in this descriptive study included distributions and cross-tabulations for the survey responses. Thirty-five percent of family physicians and 45 percent of pediatricians indicated they provide caries prevention education to their patients. Approximately half of the physicians reported performing some type of caries risk assessment. Out of 10 dental caries knowledge questions, there was not a single question that the majority of physicians answered correctly with certainty. Nine percent of family physicians and 12 percent of pediatricians reported they provided fluoride varnish treatment to their three- to six-year-old patients at the time of this survey. This study identified specific areas, related to Maryland physicians' dental caries etiology and prevention knowledge, that continuing education and training programs could enhance.

    Optical coherence tomography (OCT) is emerging as a technology that can potentially be used for the detection and monitoring of early dental enamel caries since it can provide high-resolution depth imaging of early lesions. To date, most caries detection optical technologies are well suited for examining caries at facial, lingual, incisal and occlusal surfaces. The approximal surfaces between adjacent teeth are difficult to examine due to lack of visual access and limited space for these new caries detection tools. Using a catheter-style probe developed at the NRC-Industrial Materials Institute, the probe was inserted into the interproximal space to examine the approximal surfaces with OCT imaging at 1310 nm. The probe was rotated continuously and translated axially to generate depth images in a spiral fashion. The probe was used in a mock tooth arch model consisting of extracted human teeth mounted with dental rope wax in their anatomically correct positions. With this ex vivo model, the probe provided images of the approximal surfaces revealing morphological structural details, regions of calculus, and especially regions of early dental caries (white spot lesions). Results were compared with those obtained from OCT imaging of individual samples where the approximal surfaces of extracted teeth are accessible on a lab-bench. Issues regarding access, regions of interest, and factors to be considered in an in vivo setting will be discussed. Future studies are aimed at using the probe in vivo with patient volunteers.

    Dental caries is the most common chronic oral disease, affecting 2.4 billion people worldwide who on average have 2.11 decayed, missing, or filled teeth. It impacts the quality of life of patients, socially and economically. However, the comprehension of dental caries may be difficult for most people, as it involves a multifactorial etiology with the interplay between the tooth surface, the dental biofilm, dietary fermentable carbohydrates, and genetic and behavioral factors. Therefore, the production of effective materials addressed to the education and counseling of patients for the prevention of dental caries requires a high level of specialization. In this regard, the dental caries-related contents produced by laypersons and their availability on the Internet may be low-quality information. The aim of this study was to assess the readability and the quality of dental caries-related information on Brazilian websites. A total of 75 websites were selected through Google, Bing, Yahoo!, and Baidu. The websites were organized in rankings according to their order of appearance in each one of the 4 search engines. Furthermore, 2 independent examiners evaluated the quality of websites using the DISCERN questionnaire and the Journal of American Medical Association (JAMA) benchmark criteria. The readability of the websites was assessed by the Flesch Reading Ease adapted to Brazilian Portuguese (FRE-BP). In addition, the information presented on the websites was categorized as etiology, prevention, and treatment of dental caries. The statistical analysis was performed using Spearman rank correlation coefficient, Mann-Whitney U test, hierarchical clustering analysis by Ward minimum variance method, Kruskal-Wallis test, and post hoc Dunn test. Pcaries information showed significantly higher quality scores than those with limited contents (P=.009). On the basis of this sample, dental caries-related contents available on Brazilian websites were considered simple, accessible

    Most studies have investigated the association between parental socioeconomic factors and dental caries in children based on educational and income levels; studies focusing on parental occupation, however, have been relatively limited. This cross-sectional study examined the associations between parental occupations and levels of education and household income and the prevalence of dental caries in Japanese children aged 3 years. Study subjects were 6315 children. Oral examination results were obtained from the parents or guardians, who transcribed the information recorded by medical staff at a public health center from their maternal and child health handbooks to our self-administered questionnaire. Children were classified as having dental caries if one or more primary teeth had decayed or had been filled. Adjustment was made for sex, age, region of residence, breastfeeding duration, between-meal snack frequency, toothbrushing frequency, use of fluoride, regular dental check-ups, maternal smoking during pregnancy, and living with at least one household smoker. The prevalence of dental caries was 14.7%. Compared with having an unemployed father, having a father employed in professional and engineering, clerical, sales, security, or manufacturing process was significantly associated with a lower prevalence of dental caries. Compared with having an unemployed mother, having a mother employed in professional and engineering or service was significantly inversely associated with the prevalence of dental caries. Significant inverse associations were observed between parental levels of education and household income and the prevalence of dental caries. The findings of our study suggest that parental occupation affects the prevalence of dental caries in children. We confirm that higher levels of parental education and household income decreased the prevalence of dental caries.

    To determine whether dental caries, as an indicator of cumulative exposure to sugar, is associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease, in Māori and Pacific children aged 5 and 6 years at their first dental visit. A cohort study was undertaken which linked school dental service records of caries with national hospital discharge and mortality records. Cox models were used to investigate the strength of the association between dental caries and rheumatic fever incidence. A total of 20 333 children who were free of rheumatic heart disease at enrolment were available for analysis. During a mean follow-up time of 5 years, 96 children developed acute rheumatic fever or chronic rheumatic heart disease. After adjustment for potential confounders, children with five or more primary teeth affected by caries were 57% (95% CI: 20% to 106%) more likely to develop disease during follow-up, compared to children whose primary teeth were caries free. The population attributable to the risk for caries in this cohort was 22%. Dental caries is positively associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease in Māori and Pacific children. Sugar intake, an important risk factor for dental caries, is also likely to influence the aetiology of rheumatic fever. Published by the BMJ Publishing Group Limited.

    This study aimed to explore the association between early life factors and dental caries among 5-year-old Chinese children. Data from 9722 preschool children who participated in the third National Oral Health Survey of China were analysed. Information on early life (birth weight, breastfeeding and age when toothbrushing started), child (sex, ethnicity, birth order and dental behaviours) and family factors (parental education, household income, place of residence, number of children in the family, respondent's age and relation to the child) were obtained from parental questionnaires. Children were also clinically examined to assess dental caries experience using the decayed, missing and filled teeth (dmft) index. The association of early life factors with dmft was evaluated in negative binomial regression models. We found that birth weight was not associated w
