    Full Text Available Aim: To determine the anti-carious effect of coffee in humans. Coffee represents one of the most consumed products by the population. Materials and Methods: A random sample of 1000 individuals, of both sexes, who consumed only coffee as a beverage and who visited the Out-Patient Department of KLE Society′s Institute of Dental Sci-ences, with a dental complaint and no history of any major illness, were considered as subjects. The patients′ histories with regard to the coffee intake, such as, period of consumption, frequency of consumption, whether taken with milk or wihout milk, with sugar or without sugar, and the brand make, was noted. History of the type of diet, consumption of sweets, periodic-ity of brushing, and whether they had undergone fluoride applications were also noted. A thousand patients who consumed beverages other than coffee were taken as the control. Results: The results showed that coffee most consumed was roasted coffee, and the frequency on an average was about three cups per day, for an average period of 35 years. The Decayed/Missing/Filled Surface (DMFS scores varied from 2.9, in subjects who drank black coffee, to 5.5 in subjects who consumed coffee together with sweeteners and creaming agents. The DMFS score was 3.4 in subjects who consumed coffee together with milk but no sugar. The DMFS score of the control subjects was 4, indicating that coffee if consumed alone had anticaries action, but in the presence of additives the antibacterial and anticaries action was totally minimized. Conclusion: Thus coffee can help in prevention of dental caries if consumed without additives.

    Secondary caries is a disease that occurs on the tooth after the filling has been used for a period of time. Secondary caries is also the main reason for the replacement of dental restorations. Regardless of the material used for fillings, secondary caries cannot be completely avoided. The proportion of secondary caries is very high after filling in permanent teeth or primary teeth. Secondary caries mainly occurs because of the formation of micro cracks after filling. When the micro crack width exceeds 50 microm, saliva will enter the micro cracks between the filling and tooth tissue. The cariogenic bacteria in the saliva will grow when the environment of micro cracks is appropriate, thereby producing secondary caries. The prevention of secondary caries includes micro crack control, fluoride use, teeth cleaning, tooth decay and gum disease treatment, and regular checkups. PMID:24881200

  5. The role of chlorhexidine in caries prevention.

    2008-01-01

    The use of chlorhexidine for caries prevention has been a controversial topic among dental educators and clinicians. In several reviews, it has been concluded that the most persistent reduction of mutans streptococci have been achieved by chlorhexidine varnishes, followed by gels and, lastly, mouth rinses. Also, the evidence for using different chlorhexidine modes or a combination of chlorhexidine-fluoride therapy for caries prevention has been "suggestive but incomplete". Variable study designs and lack of data in high-risk children and adults support the need to continue conducting randomized, well-controlled clinical trials and to search for a practical, effective mode of antimicrobial treatment that augments the known effect of fluoride treatments. Currently, the only chlorhexidine-containing products marketed in the United States (US) are mouthrinses containing 0.12 percent chlorhexidine. Based on the available reviews, chlorhexidine rinses have not been highly effective in preventing caries, or at least the clinical data are not convincing. Due to the current lack of long-term clinical evidence for caries prevention and reported side effects, chlorhexidine rinses should not be recommended for caries prevention. Due to the inconclusive literature and sparse clinical data on gels and varnishes, their use for caries prevention should also be studied further to develop evidence-based recommendations for their clinical role in caries prevention. Since dental caries is a disease with a multifactoral etiology, it is currently more appropriate to use other established, evidence-based prevention methods, such as fluoride applications, diet modifications and good oral hygiene practices. Recent findings also indicate that the effect of an antimicrobial agent for reducing the levels of mutans streptococci or plaque reduction may not always correlate with eventual caries reduction. The clinically important outcome is proven reductions in caries. Many advances in the

    Dental caries is considered as the most common polymicrobial oral disease in the world. With the aim of developing alternative approaches to reduce or prevent the decay, numerous papers showed the potential anticaries activity of a number of natural products. The natural products with anticaries effects are selected from e.g. food, beverages, flowers or traditional herbs. Most of the effective components are proven to be polyphenol compounds. Many of the natural products are studied as antibacterial agents, while some of them are found to be effective in shifting the de-/remineralization balance. However, the mechanisms of the anticaries effects are still unclear for most of the natural products. In the future, more efforts need to be made to seek novel effective natural products via in vitro experiment, animal study and in situ investigations, as well as to enhance their anticaries effects with the help of novel technology like nanotechnology.

    Full Text Available Probiotics have the potential to provide significant benefits to human health, so we decided to investigate the probiotics species that may have preventive action against dental caries mainly in children in order to determine if there can be created a preventive medicine, made from probiotics found in the oral cavity. Oral probiotics that have shown promising activities in the prevention of dental caries are: Streptococcus salivarius (strain K12, BGH01 Lactobacillus salivarius, BGH089 gasseri Lactobacillus, Streptococcus sanguinis and Streptococcus oligofermentans. In vitro studies on the use of probiotics for the prevention of dental caries have shown interesting results, but in vivo they are not very encouraging. It is necessary to deepen in the therapeutic effects of probiotics strains already discovered in order to obtain from them an effective preventive agent against dental caries and so ensuring a better quality of life, especially in children.

    To investigate the effectiveness of 3 caries-preventive measures on high- and low-caries risk occlusal surfaces of first permanent molars over 3 y. This cluster-randomized controlled clinical trial covered 242 schoolchildren, 6 to 7 y old, from low socioeconomic areas. At baseline, caries risk was assessed at the tooth surface level, through a combination of ICDAS II (International Caries Detection and Assessment System) and fissure depth codes. High-caries risk occlusal surfaces were treated according to daily supervised toothbrushing (STB) at school and 2 sealants: composite resin (CR) and atraumatic restorative treatment-high-viscosity glass-ionomer cement (ART-GIC). Low-caries risk occlusal surfaces received STB or no intervention. Evaluations were performed after 0.5, 1, 2, and 3 y. A cavitated dentine carious lesion was considered a failure. Data were analyzed according to the proportional hazard rate regression model with frailty correction, Wald test, analysis of variance, and t test, according to the jackknife procedure for calculating standard errors. The cumulative survival rates of cavitated dentine carious lesion-free, high-caries risk occlusal surfaces were 95.6%, 91.4%, and 90.2% for STB, CR, and ART-GIC, respectively, over 3 y, which were not statistically significantly different. For low-caries risk occlusal surfaces, no statistically significant difference was observed between the cumulative survival rate of the STB group (94.8%) and the no-intervention group (92.1%) over 3 y. There was neither a difference among STB, CR, and ART-GIC on school premises in preventing cavitated dentine carious lesions in high-caries risk occlusal surfaces of first permanent molars nor a difference between STB and no intervention for low-caries risk occlusal surfaces of first permanent molars over 3 y.

    2007-09-01

    The aim of this paper was to critically review the current role of community water fluoridation in preventing dental caries. Original articles and reviews published in English language from January 2001 to June 2006 were selected through MEDLINE database. Other sources were taken from the references of the selected papers. For the past 50 years community water fluoridation has been considered the milestone of caries prevention and as one of the major public health measures of the 20th century. However, it is now accepted that the primary cariostatic action of fluoride occurs after tooth eruption. Moreover, the caries reduction directly attributable to water fluoridation have declined in the last decades as the use of topical fluoride had become more widespread, whereas enamel fluorosis has been reported as an emerging problem in fluoridated areas. Several studies conducted in fluoridated and nonfluoridated communities suggested that this method of delivering fluoride may be unnecessary for caries prevention, particularly in the industrialized countries where the caries level has became low. Although water fluoridation may still be a relevant public health measure in poor and disadvantaged populations, the use of topical fluoride offers an optimal opportunity to prevent caries among people living in both industrialized and developing countries.

    The aim of this prospective study was to determine the effectiveness of caries preventive measures started during pregnancy on the caries experience of first-time mothers and their infants. Eighty-one pregnant women with low social background were selected on the basis of the presence of active carious lesions and were randomly divided into control (38) and experimental (43) groups. The initial dental status (DMFS and white spot lesions) was established through clinical examination. The prophylactic measures were repeated during pregnancy and 6 and 12 months after delivery. Both groups received primary care intervention. They were instructed in relation to the etiologic factors of dental caries and received oral hygiene kits. Oral hygiene instructions were reinforced through interactive brushing. The experimental group also received antimicrobial treatment (topical application of NaF and iodine solution immediately after prophylaxis and 3 and 5 days later) and restorative care using glass ionomer cement. By the time the children were 2 years of age, 33.3% of the infants in the control group and 14.7% in the experimental group had caries activity. A significant difference in caries prevalence was observed between children with and without visible dental plaque. The mean number of tooth surfaces with carious lesions (including areas of demineralization) was higher among the children in the control group compared to the experimental group (6.3 x 3.2), however, with no statistical significance. Maternal caries increase was a significant factor influencing the caries experience of the children. These data support the evidence of an association between caries prevalence in young children and clinical (dental plaque) and maternal factors. PMID:12964648

  19. Dental caries: Strategies to control this preventable disease

    Full Text Available Objective. 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. Conclusion. Dental caries is preventable – individuals, communities and countries need strategies to achieve this.

  20. Nd:YAG laser in caries prevention: a clinical study

    International Nuclear Information System (INIS)

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 μm, resulting in an energy density of 84,9 J/cm2. The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

  2. Chlorhexidine solutions, gels and varnishes in caries prevention.

    To combat dental caries, a chemical has been sought that possesses stronger antimicrobial properties than fluoride in support of its physicochemical tooth-protecting properties. These searches have led to several agents, of which chlorhexidine (CH) appears most effective. To reduce local side effects of the well-known 0.2% CH mouthwash, a 0.05% CH gluconate + 0.04% NaF solution, pH 5.9, has been developed. Use of this combination over a 2-year period resulted in a 53% reduction in caries increment and a 75% reduction in gingival bleeding, i.e. a clear duality of prevention of oral disease (Luoma et al. 1978). Staining of teeth was minimal and easily removable in about one third of the subjects. To lessen the contribution of patients, chlorhexidine gels, without but more especially with fluoride have been professionally administered. Reductions in salivary mutans streptococci after short periods of gel applications have been found to persist longer than reductions after brief periods of mouthwashing. Reductions of approximal caries increment by about 50% in children, and root surface caries in adults have been obtained through use of CH gels. The effect on root surface caries in adults was equal to that obtained through use of local fluoride applications. Dental CH varnish seems promising, especially because a very short contact time with a tooth may be sufficient to reduce mutans streptococci. No simultaneous effects against caries and gingivitis of CH gels or varnishes has been reported. Comparisons of CH solutions, gels and varnishes, with or without fluoride, in relation to their potentials for preventing oral disease in subjects at risk remain to be accomplished. PMID:1298965

    Streptococcus mutans is a Gram-positive bacterium involved in development to caries, the most common infectious disease of our time. Streptococcus mutans interacts with other microbes, like the fungus Candida albicans and both are commonly isolated from patients with caries. Since the role of C. albicans in caries remains unknown, our aim was to unravel this using an in vitro dual-species cariogenic oral biofilm model. Biofilms were grown for 24-72 h on glass cover slips or hydroxyapatite (HA) disks to mimic the surface of teeth. Medium pH, lactic acid production capacity and calcium release from HA disks were determined. All 24-h biofilms had external pH values below the critical pH of 5.5 where enamel dissolves. In contrast, 72-h dual-species biofilms had significantly higher pH (above the critical pH) and consequently decreased calcium release compared to single-species S. mutans biofilms. Counter intuitively, lactic acid production and growth of S. mutans were increased in 72-h dual-species biofilms. Candida albicans modulates the pH in dual-species biofilms to values above the critical pH where enamel dissolves. Our results suggest that C. albicans is not by definition a cariogenic microorganism; it could prevent caries by actively increasing pH preventing mineral loss. PMID:27129365

Investigations in vitro into metabolic activity, co-aggregation, growth inhibition, bacteriocin production, and adhesion have collectively suggested a potential role for probiotic lactobacilli and bifidobacteria to modulate the oral microbial ecology. Likewise, short-term clinical studies with intermediate microbial endpoints indicate that interference with caries-associated bacteria seems possible through probiotic dairy products, tablets, lozenges and chewing gum in various dose regimens. Few randomized controlled clinical trials with caries outcomes are available, but three studies with preschool children and the elderly have demonstrated preventive fractions between 21% and 75%, following regular intake of milk supplemented with probiotic lactobacilli. However, further large-scale trials with orally derived anti-caries candidates are needed before we can say that we are ready for bacteriotherapy as an adjunct to complement the existing evidence-based methods for preventing and controlling caries in daily practice.

    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.

    Many reviews support fluoride varnish (FV) as a caries-inhibitory agent. Evidence from 6 Cochrane systematic reviews involving 200 trials and more than 80,000 participants further confirms the effectiveness of FV, applied professionally 2-4 times a year, for preventing dental caries in both primary and permanent teeth. The relative benefit of FV application seems to occur irrespective of baseline caries risk, baseline caries severity, background exposure to fluorides, use of fluoride toothpaste and application features such as prior prophylaxis, concentration of fluoride or frequency of application. While the efficacy of FV is acknowledged in clinical practice guidelines globally, the implementation of this recommendation may still be an issue. Factors that may facilitate FV application in the USA include Medicaid eligibility, relationships with dentists/community centers and strong cooperation and communication between physicians and support staff. Barriers include insufficient time to integrate oral health services into well-child visits, difficulty in applying FV (lack of skills/training) and resistance among colleagues and staff. Research in the UK/Scotland also suggests encouraging clinicians in their motivation to perform this treatment and addressing professional and parental concerns relating to possible negative consequences may be influential. Further research targeting cost-effectiveness and how FV in routine care may fit in with political agendas relating to, for example, inequalities in health care provision and access will also play a key part in stakeholder decisions to put resources into this issue.

Studies that used other formulations of CCP-ACP were excluded. Trials using split-mouth design were also excluded. Only English language papers were considered.Data extraction and synthesisPapers were assessed independently by both authors using the Cochrane Collaboration tool for assessing risk of bias in randomised trials.1 Meta-analysis was not possible due to study heterogeneity.ResultsTwelve studies were available for the final review; three studies on caries prevention were assessed as having low risk of bias. The remaining nine studies, with high risk of bias, reported on treatment or regression of early carious lesions. Two RCTs reported no significant benefits in the use of Tooth Mousse(®) over brushing with a fluoride toothpaste, a third study demonstrated a statistically significant increase in enamel microhardness for the Tooth Mousse(®) group compared to control group but no difference to the group who had fluoride gel treatment. Overall the authors concluded that Tooth Mousse(®) performs no better than fluoride in the prevention of carious lesions.Seven of nine studies evaluated caries lesion severity in orthodontic patients, with four demonstrating statistically significant white spot regression. Two trials in non-orthodontic patients showed statistically significant remineralising potential of Tooth Mousse(®) over fluoride mouthrinse or the regular use of fluoride toothpaste in 14-30 days.ConclusionsThe authors found no evidence to support the use of Tooth Mousse(®) over brushing with a fluoride toothpaste for the prevention of early caries.

    2014-08-01

    Full Text Available : INTRODUCTION: Patients undergoing fixed orthodontic therapy are at high risk of developing decalcification, caries and white spot lesions. AIM: As little information is available about preventive measures taken by orthodontists, this study surveyed the measures used by orthodontists those practicing in Rajasthan in prevention of such problems. MATERIALS AND METHODS: A questionnaire regarding preventive measures undertaken before, during and after the orthodontic treatment was sent to 128 orthodontists, out of them 100 orthodontists replied to the questionnaire. All the data obtained from this questionnaire was tabulated and analyzed statistically using ANOVA test. RESULTS: Before starting the treatment, majority of orthodontists always prescribed oral hygiene instructions and recommended the use of fluoride rinses while chlorhexidine rinses and other cleansing aids were usually recommended. During the treatment when demineralization was seen developing, majority of orthodontists explained the consequences, gave extra oral hygiene instructions and recommended the use of fluoride rinses as well as other oral hygiene aids which was found to be statistically significant (p < 0.05. At the completion of treatment, majority of orthodontists always gave extra oral hygiene instructions and recommended the use of fluoride rinses as well as fluoride gel. Fluoride varnish, chlorhexidine rinses, oral hygiene aids like brushes and other measures such as polishing of white spot lesions were occasionally recommended which was also found to be statistically significant (p < 0.05. CONCLUSION: Rajasthani orthodontists undertake satisfactory measures to prevent demineralization and caries within practical limits.

    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.

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 from the early 1980s onwards. Numerous peer-reviewed publications in international journals showed clearly the bioavailability of fluoride in milk, and increased concentrations of fluoride in saliva, dental plaque, dental enamel and dentine, and urine, after consumption of fluoridated 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 programs. These evaluations showed clearly that the optimal daily intake of fluoride in milk is effective in preventing dental caries. At present, milk fluoridation programs are running continuously in about ten countries of the world. 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 program. The program should aim to provide fluoridated milk for at least 200 days per year and should commence before the children are 4 years of age. PMID:18078140

    2003-03-01

    Early Childhood Caries is a significant public health problem in Palau. Data have shown that nearly 80% of children ages 3-5 years of age in Palau experience dental caries and a significant number of these children require general anesthesia to treat or remove painful or infected carious teeth. In response to this growing problem, the Division of Oral Health has systematically developed a prevention program in collaboration with the Maternal and Child Health Unit under the Ministry of Health. The core program involves integrating preventive oral health services into all regular prenatal and postnatal care programs and improving the capacities of health professionals to provide such services. The program promotes the idea that oral health is an important component to overall health and all efforts are made to integrate oral health into broader public health initiatives. Both health and process outcomes are being monitored by an oral health surveillance system, while preliminary data show improved oral health among young children. This paper takes a closer look at the development of the Palau program. PMID:16276951

    Full Text Available Oral and dental health has got improvement tremendously over the last century but the prevalence of dental caries in children has remained a significant clinical problem. Caries risk varies between individuals according to each subject’s balance between factors exposing to and protecting from caries attack. It is important to assess the risk of caries for all patients on a routine basis. Caries risk is divided into three levels: high, moderate, and low. Thereby, the dental professional is better to make a specific prevention and treatment recommendations to reduce a child risk and improve overall oral health. The goal of caries-risk assessment and preventive treatment is to eliminate caries or at least to reduce the high-caries occurrence down to the level of the remaining part of the age group. Preventive treatment is divided into three parts: primary, secondary, and tertiary prevention. This paper describes the primary prevention in children with high caries risk by behavior modification and tooth protection. Behavior modification is about dental health education, oral hygiene, diet and sugar consumption, sugar-free chewing gum and sugar-free medicines. Tooth protection is about sealant, usage of flouride and chlorhexidine.

  1. Radiation-related caries. Etiology and possible preventive strategies. What should the radiotherapist know?

    International Nuclear Information System (INIS)

    After radiation treatment of head-and-neck cancer, the impairment of patient's quality of life still remains an issue. After completion of the treatment course, a substantial number of patients develop so-called radiation caries. In addition, almost 50% of all cases of infectious osteoradionecrosis (iORN) of the jaws are directly associated with radiation caries. This review addresses our current knowledge on the etiology and pathogenesis of radiation caries including possible preventive strategies. Materials and methods A PubMed search using the terms ''radiation caries'' (''radiation related caries'', ''radiation related damage to dentition'') and ''radiogenic caries'' (''postradiation caries'', ''dental complications and radiotherapy'') was performed. The analysis of its content focused on the etiology, the pathogenesis, and the available knowledge on prophylaxis as well as treatment of radiation caries. Results For this review, 60 publications were selected. As main causal factors for radiogenic caries, either indirect impairment, resulting from alterations in the oral environment (e.g., radiation-induced xerostomia) or direct radiation-induced damage in teeth hard tissues are discussed. Radiation caries remains a lifelong threat and, therefore, requires permanent prevention programs. Conclusion To enable optimal medical care of the patients during the time course of radiotherapy as well as afterwards, close interdisciplinary cooperation between radiotherapists, oral surgeons, otorhinolaryngologists, and dentists is absolutely essential.

    Full Text Available Abstract Background Dental caries is one of the primary causes of tooth loss among adults. It is estimated to affect a majority of Americans aged 55 and older, with a disproportionately higher burden in disadvantaged populations. Although a number of treatments are currently in use for caries prevention in adults, evidence for their efficacy and effectiveness is limited. Methods/Design The Prevention of Adult Caries Study (PACS is a multicenter, placebo-controlled, double-blind, randomized clinical trial of the efficacy of a chlorhexidine (10% w/v dental coating in preventing adult caries. Participants (n = 983 were recruited from four different dental delivery systems serving four diverse communities, including one American Indian population, and were randomized to receive either chlorhexidine or a placebo treatment. The primary outcome is the net caries increment (including non-cavitated lesions from baseline to 13 months of follow-up. A cost-effectiveness analysis also will be considered. Discussion This new dental treatment, if efficacious and approved for use by the Food and Drug Administration (FDA, would become a new in-office, anti-microbial agent for the prevention of adult caries in the United States.

    Full Text Available Until recently, the standard of care for early childhood caries (ECC has been primarily surgical and restorative treatment with little emphasis on preventing and managing the disease itself. It is now recognized that surgical treatment alone does not address the underlying etiology of the disease. Despite costly surgeries and reparative treatment, the onset and progression of caries are likely to continue. A successful rebalance of risk and protective factors may prevent, slow down, or even arrest dental caries and its progression. An 18-month risk-based chronic disease management (DM approach to address ECC in preschool children was implemented as a quality improvement (QI collaborative by seven teams of oral health care providers across the United States. In the aggregate, fewer DM children experienced new cavitation, pain, and referrals to the operating room (OR for restorative treatment compared to baseline historical controls. The teams found that QI methods facilitated adoption of the DM approach and resulted in improved care to patients and better outcomes overall. Despite these successes, the wide scale adoption and spread of the DM approach may be limited unless health policy and payment reforms are enacted to compensate providers for implementing DM protocols in their practice.

    Full Text Available Objective: To evaluate an educative/preventive program to control caries disease in 160 babies, ages ranging from 1 to 21 months. Method: The selected children, healthy and without caries, were examined once every three months during 15 months. In each appointment, the biofilm was removed with gauze and a baby’s toothbrush, according to the child’s age. After visual examination, the number of teeth and eventual alterations were recorded. Mothers were guided to perform suitable preventive activities through personal orientation, posters and slides. There were educational lectures at the beginning of the research, as well as every six months. The oral examination and the hygiene training of the mothers were conducted at the health units, community centers and a university. Aiming to verify the changes in the feeding and hygiene habits, questionnaires were applied at the beginning of the study and 12 months later. Results: The majority of the mothers hadn’t completed elementary school and the family income ranged from 1 to 3 minimum salaries. After 15 months, the drop-out rate was 23.8%. The incidence of caries, which was 7.3% in the 122 babies, evaluated with an average of 0.25 teeth with caries. Including the black spots, the incidence of caries was 9.8%, with an average of 0.4 teeth with caries. Conclusion: The educative/preventive program contributed to a lower caries incidence, and it stimulated the adoption of healthier habits. There was a decrease of 33% in night time bottle-feeding, and an increase of 20.9% in oral hygiene.

    Full Text Available Objective. To characterize the oral health-related attitudes and behavior of Czech parents of preschool children. Materials and methods. A representative sample of 796 parents was recruited for the crosssectional questionnaire survey. Study data were collected using a validated questionnaire with 44 attitudinal items related to different aspects of caries prevention. The data were analyzed by explorative factor analysis, extracted factors were subjected to reliability analysis and Kruskal–Wallis ANOVA was used to test differences in the factor scores in respondents with different levels of education and selfperceived SES. Results. The factor analysis extracted 3 factors, labeled ”Toothbrushing – perceived significance and parental efficacy”; ”External caries control” and ”Internal caries control”. They explained 28.9% of the data variability. The comparison of the factor scores in groups with different SES and education of mothers showed highly significant differences. For all three factors, median values of the aggregated Likert scale increased with increasing SES and education of the mother. Conclusion. The parents report that they are aware of their responsibility for the prevention of tooth decay in their children. In caries prevention they concentrate on toothbrushing. Dietary measures do not seem to be of similar importance to them. The increasing self-perceived SES of the family and the education level of the mother have a significantly positive effect on the caries-preventive attitudes of the parents. Based on the study results, the message to the publichealth sector in the Czech Republic should include the need to highlight the importance of a non-cariogenic diet and the role of fluorides in caries prevention.

    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. PMID:26781572

    Obesity and dental caries in childhood are among the major public health concerns described as a global pandemic because of their global distribution and severe consequences. A consensus has developed as to a recently emerging and alarming common risk factor that leads to the double burden of dental caries and obesity; energy-dense foods (sugar-coated cereals, high-sugar yogurt, soft drinks) are becoming very popular among children because of their dense marketing, cheaper price, increased supply and variety. Implementation of health-promoting and -supporting marketing strategies for healthy food can be one initial cornerstone for successful application of the common risk factor approach in prevention of obesity and dental caries, as also suggested by World Health Organization. Labelling healthy food with a 'health-friendly' logo, illustrating that the teeth and the heart are both parts of the whole body (standing side by side supporting each other as close friends), both happy and protected because of consumption of healthy food for the whole body, can promote the foods that are friendly to health of the whole body, implementing the common risk factor approach under a single theme. Labelling healthy food as 'health-friendly' based on an international consensus will provide a clear and uniform picture of what is healthy to eat and result in an international integrated programme for prevention of obesity and caries.

    Steffen Mickenautsch

    Full Text Available INTRODUCTION/AIM: To appraise the clinical literature in determining whether loss of complete sealant retention as surrogate endpoint is directly associated with caries occurrence on sealed teeth as its clinical endpoint and to apply the appraised evidence in testing the null-hypothesis that the retention/caries ratio between different types of sealant materials (resin and glass-ionomer cement is not statistically significant (= Prentice criterion for surrogate endpoint validity. METHODS: Databases searched PubMed/Medline, Directory of Open Access Journals; IndMed, Scielo. Systematic reviews were checked for suitable trials. The search terms: "fiss* AND seal*" and "fissure AND sealant" were used. Article selection criteria were: clinical trial reporting on the retention and caries occurrence of resin and/or glass-ionomer cement (GIC fissure sealed permanent molar teeth; minimum 24-month follow-up period; systematic review or meta-analysis. Datasets and information were extracted from accepted trials. The principle outcome measure was the ratio of Risk of loss of complete retention to the Risk of caries occurrence per sealant type (RCR. Risk of bias was assessed in trials and sensitivity analysis with regard to potential confounding factors conducted. The null-hypothesis was tested by graphical and statistical methods. RESULTS: The risk of loss of complete retention of sealant materials was associated with the risk of caries occurrence for resin but not for GIC based sealants. The difference between RCR values of the two sealant types was statistically significant (p<0.05. The null-hypothesis was rejected. CONCLUSIONS: The current clinical evidence suggests that complete retention of pit and fissure sealants may not be a valid surrogate endpoint for caries prevention as its clinical endpoint. Further research is required to corroborate the current results.

  3. The evidence base for professional and self-care prevention - caries, erosion and sensitivity

    2015-01-01

    Background The aim of this conference paper was to examine the evidence base for primary and secondary prevention of dental caries, erosions and dentin hypersensitivity through professional and self-care measures. Methods A mapping of systematic reviews (SR) of literature was carried out in PubMed and the Cochrane library through April 2014 using established MeSH-terms and disease-related search words in various combinations. The search was restricted to SR's published in English or Scandinavian and all age groups were considered. The reference lists of the selected papers were hand-searched for additional review articles of potential interest. Meta-analyses, guidelines and treatment recommendations were considered only when SR's were lacking. In the event of updates or multiple systematic reviews covering the same topic, only the most recent article was included. No quality assessment of the systematic reviews was carried out. The quality of evidence was rated in four levels according to the GRADE scale. Results In total, 39 SR were included. For primary caries prevention, the quality of evidence was high for the use of fluoride toothpaste (with and without triclosan) and moderate for fluoride varnish and fissure sealants. The quality of evidence for fluoride gel, fluoride mouth rinse, xylitol gums and silver diamine fluoride (SDF) was rated as low. For secondary caries prevention and caries arrest, only fluoride interventions and SDF proved consistent benefits, although the quality of evidence was low. Likewise, the GRADE score for preventing erosions located in the enamel with fluoride supplements was low. The quality of evidence for various professional and self-care methods to prevent and manage dentine hypersensitivity was very low. Conclusions There are knowledge gaps in many domains of cariology and preventive dentistry that must be addressed and bridged through clinical research of good quality. PMID:26392204

    Full Text Available Probiotics have the potential to provide significant benefits to human health, so we decided to investigate the probiotics species that may have preventive action against dental caries mainly in children in order to determine if there can be created a preventive medicine, made from probiotics found in the oral cavity. Oral probiotics that have shown promising activities in the prevention of dental caries are: Streptococcus salivarius (strain K12, BGH01 Lactobacillus salivarius, BGH089 gasseri Lactobacillus, Streptococcus sanguinis and Streptococcus oligofermentans. In vitro studies on the use of probiotics for the prevention of dental caries have shown interesting results, but in vivo they are not very encouraging. It is necessary to deepen in the therapeutic effects of probiotics strains already discovered in order to obtain from them an effective preventive agent against dental caries and so ensuring a better quality of life, especially in children.Los probióticos tienen el potencial de brindar beneficios muy importantes para la salud humana, por lo que se decidió investigar las especies probióticas que pudiesen tener acción preventiva contra la caries dentales fundamentalmente en los niños, para determinar la existencia de un medicamento contra ellas, a partir de microorganismos probióticos presentes en la cavidad bucal. Los probióticos bucales que han demostrado acciones alentadoras en la prevención de las caries dentales son: el Estreptococos salivarius (cepa K12, Lactobacilos salivarius BGH01, Lactobacilos gasseri BGH089, Estreptococos sanguinis y Estreptococos oligofermentans. Los estudios in vitro sobre el uso de probióticos para la prevención de las caries dentales poseen resultados interesantes, pero, in vivo, estos no son muy alentadores. Se debe profundizar en los efectos terapéuticos de las cepas probióticas ya descubiertas para que se puedan obtener de estas un agente preventivo efectivo contra las caries, para poder

    Full Text Available Abstract Background The 'high-risk approach' is a commonly adopted strategy recommended for the prevention of dental caries in populations. The scientific basis for the strategy has been questioned. The objective of this study is to assess the contribution that children identified at 'high-risk' made towards the total of new caries lesions over a 4-year period, by analysing the distribution of new lesions per 100 children. Methods Data are from the National Preventive Dentistry Demonstration Programme (NPDDP in the United States. The analyses identified the distribution of new carious lesions over a 4-year period in four groups of 7 year-old children who received differing preventive regimes. Results The majority of new lesions occurred in those children classified at lowest caries risk at baseline. Irrespective of the preventive regime adopted and the initial caries levels, children classified as 'highest risk' contributed less than 6% of the total number of new lesions developing over 4 years. Conclusion These findings challenge the basis for the adoption of a high-risk strategy.

    2015-01-01

    Full Text Available Introduction. Pregnancy may pose an increased risk for the development of caries and other oral health problems. Continuous screening of oral health status, implementing appropriate preventive measures (particularly oral hygiene, healthy diet plans and education is of paramount importance not only for oral health but also for the general health status of the future mother and her offspring. Effects of Food on Caries Development. Caries prevention through healthy diet implicates the reduction in frequency and amount of intake of cariogenic food, above all of refined carbohydrates, i.e. sugars and sweets. Foods known to have caries-prophylactic effects should predominate in healthy diet plans. They mainly include solid foods, which have mechanical effects on teeth cleaning, as well as foods providing sufficient amounts of vitamins (A, C, D and a variety of elements and compounds (calcium, phosphates, fluorides favoring the preservation and remineralization of tooth structures. Education of Pregnant Women on Healthy Deit. In accomplishing these goals, education and direct positive communication between the educator and the pregnant woman play a crucial role. Educative approach is always individual and determined by the patient’s specific cultural and socioeconomic features and status, as well as her habits, motivation and willingness to accept relevant recommendations. Accomplishing the aforementioned goals requires the appropriate organization and professional competence within the preventive dental service and its close cooperation with the relevant medical institutions and social support in the framework of public health protection. Conclusion. Preserving of oral health during pregnancy is predominantly influenced by the following factors: 1 healthy diet, 2 oral hygiene, 3 patients’ education, 4 regular control of oral health, 5 appropriate organization of dental services and 6 community engagement.

    Abstract Background Dental caries is a persistent public health problem with little change in the prevalence in young children over the last 20 years. Once a child contracts the disease it has a significant impact on their quality of life. There is good evidence from Cochrane reviews including trials that fluoride varnish and regular use of fluoride toothpaste can prevent caries. The Northern Ireland Caries Prevention in Practice Trial (NIC-PIP) trial will compare the costs and effects of a caries preventive package (fluoride varnish, toothpaste, toothbrush and standardised dental health education) with dental health education alone in young children. Methods\\/Design A randomised controlled trial on children initially aged 2 and 3 years old who are regular attenders at the primary dental care services in Northern Ireland. Children will be recruited and randomised in dental practices. Children will be randomised to the prevention package of both fluoride varnish (twice per year for three years), fluoride toothpaste (1,450 ppm F) (supplied twice per year), a toothbrush (supplied twice a year) or not; both test and control groups receive standardised dental health education delivered by the dentist twice per year. Randomisation will be conducted by the Belfast Trust Clinical Research Support Centre ([CRSC] a Clinical Trials Unit). 1200 participants will be recruited from approximately 40 dental practices. Children will be examined for caries by independent dental examiners at baseline and will be excluded if they have caries. The independent dental examiners will examine the children again at 3 years blinded to study group. The primary end-point is whether the child develops caries (cavitation into dentine) or not over the three years. One secondary outcome is the number of carious surfaces in the primary dentition in children who experience caries. Other secondary outcomes are episodes of pain, extraction of primary teeth, other adverse events and costs which will

    The authors present the results of three years' activity relating to "caries' prevention" in comparison with data concerning the research of previous five years. The average and standard deviations of DMFT values with regard to the permanent teeth and dmft concerning the deciduous ones, obtained from the dental visit of 222 children attending the 1st and the 3rd class of the primary school and 1st class of the secondary school, has demonstrated a statistically significant reduction of caries, compared with data concerning 749 pupils of the same standards in the period from 1984 to 1988. This fact confirms that the programme defined by U.S.L. n. 15 "Alta Val di Cecina", including sanitary education for children of primary school with their parents and teachers, besides dental examinations to the filter classes, is a valid instrument to obtain the reduction of carious' pathology in evolutive age.

    The present study evaluated teaching that recent graduates in Finland had received in caries prevention and their perceived need for updated Best Practice Guidelines. A two-page questionnaire was mailed to all dentists in Finland who had graduated from 1995 to 1998 (n = 390). After one reminder, the response rate was 46%. The closed questions covered teaching in 14 caries-preventive methods and its suggestions as to when and on whom to apply such methods. Each dentist's own opinion on the three most important methods for caries prevention in patients with various types of dentition was sought in open questions. The respondents reported that at dental school, on average 12.5 (SD = 2.4) of 14 aspects of caries prevention were covered in theoretical teaching, 5.5 (SD = 3.8) in demonstrations and 8.5 (SD = 3.0) in clinical training. The top four methods teaching suggested for every patient were toothbrushing (100%), use of fluoridated toothpaste (99%), interdental cleaning (98%), and use of xylitol (97%); followed by fluoride varnish (77%) and fissure sealants (54%). The three caries-preventive methods the respondents felt to be most useful were the same for all types of dentitions, in order of importance: (i) toothbrushing and use of fluoridated toothpaste, (ii) supplementary use of fluorides at home and (iii) healthy dietary habits, in particular, avoidance of sucrose. As regards clinical work, such teaching had served the respondents' real-life needs in patients' caries prevention either extremely (44%) or moderately (54%) well; 91% said, however, that they would benefit from nationwide Best Practice Guidelines. In conclusion, the recent graduates' emphasis on patient-active methods in caries prevention may indicate a change in the current policy favouring patient-passive methods. PMID:14717684

    Full Text Available The dental health of preschool children with congenital heart disease (CHD is usually poor, which may contribute to the development of infective endocarditis (IE. Primary care physicians play an important role in providing access to preventive dental services, particularly for preschool children. The object of this study was to provide epidemiologic evidence for the impact of primary care physicians’ (PCP’s counseling role on early childhood caries in children with CHD in Guangzhou, China, which might guide future caries prevention to decrease the risk of IE in children with CHD. A hospital-based, case-control study was performed, which contained 100 children with newly diagnosed early childhood caries and 100 matched (sex and age children without dental caries. All of the subjects were diagnosed with CHD at birth and recruited from Guangdong Cardiovascular Institute from 2012 through 2013. A conditional multivariate logistic-regression model was used to assess the associations between PCPs’ role and early childhood caries with a significance level of 5%. Our findings revealed that mother’s education level (OR = 0.36, CL = 0.14–0.92 and knowledge, being educated on the relationship between CHD and infective endocarditis (OR = 0.48, CL = 0.25–0.94 and the impact of oral health on infective endocarditis (OR = 0.37, CL = 0.18–0.79 by the PCP were associated with early childhood caries.

    A preventive dental program (PDP) instituted in pregnant women and comprising an educational and a preventive part was evaluated when their children were five and six years of age. Dental caries was examined in sixty-seven mother-child pairs belonging to the program and in sixty-nine control mother-child pairs. In the five-year-old children 87 percent of the PDP group were caries free compared with the 50 percent in the control group. Comparable figures for six-year-old children were 89 percent and 62 percent in the PDP and control group, respectively. The mean dft of the PDP children five and six years of age was 0.4 and 0.2, respectively, versus 1.3 and 1.4 for the control children. The differences in caries-free status and caries prevalence were statistically significant. In conclusion, the preventive dental program which started in pregnant women and continued in the mothers and their children were highly effective for a long-term reduction of dental caries.

    Full Text Available Abstract Background Dental caries is unevenly distributed within populations with a higher burden in low socio-economy groups. Several attempts have been made to allocate resources to those that need them the most; there is a need for convenient approaches to population-based monitoring of caries risk over time. The aim of this study was to develop the geo-map concept, addressing time trends in caries risk, and demonstrate the novel approach by analyzing epidemiological data from preschool residents in the region of Halland, Sweden. Methods The study population consisted of 9,973 (2006 and 10,927 (2010 children between 3 to 6years of age (~77% of the eligible population from whom caries data were obtained. Reported dmfs>0 for a child was considered as the primary caries outcome. Each study individual was geo-coded with respect to his/her residence parish (66 parishes in the region. Smoothed caries risk geo-maps, along with corresponding statistical certainty geo-maps, were produced by using the free software Rapid Inquiry Facility and the ESRI ArcGIS system. Parish-level socioeconomic data were available. Results The overall proportion of caries-free (dmfs=0 children improved from 84.0% in 2006 to 88.6% in 2010. The ratio of maximum and minimum (parish-level smoothed relative risks (SmRRs increased from 1.76/0.44=4.0 in 2006 to 2.37/0.33=7.2 in 2010, which indicated an increased geographical polarization of early childhood caries in the population. Eight parishes showed evidential, positional changes in caries risk between 2006 and 2010; their corresponding SmRRs and statistical certainty ranks changed markedly. No considerable parallel changes in parish-level socioeconomic characteristics were seen during the same time period. Conclusion Geo-maps based on caries risk can be used to monitor changes in caries risk over time. Thus, geo-mapping offers a convenient tool for evaluating the effectiveness of tailored health promotion and preventive

    Primary, secondary, and tertiary preventive dental services have the potential for achieving the triple aim of better health outcomes for populations, better patient experience of care, and lower per capita costs. Yet, maximization of preventive services has not occurred in dental practice nor been promoted by dental plans. While the lack of such things as diagnostic codes, caries classification systems, and validated risk assessment tools are barriers to increasing preventive care, they may not be the primary barriers that need to be addressed. The purpose of this paper was to focus on three issues: (1) the dental care business model based on a value proposition of surgical care rather than preventive care; (2) the benefit plan design that undervalues or does not cover effective primary, secondary, and tertiary preventive services; and (3) the current financial crisis in health care. It is the business model of dental practice and the benefit design of payers that are the biggest barriers that will have to change to transform dental care into a more effective and efficient means of achieving and maintaining health.

    2016-04-01

    The Cochrane Review on water fluoridation for the prevention of dental caries was published in 2015 and attracted considerable interest and comment, especially in countries with extensive water fluoridation programmes. The Review had two objectives: (i) to evaluate the effects of water fluoridation (artificial or natural) on the prevention of dental caries, and (ii) to evaluate the effects of water fluoridation (artificial or natural) on dental fluorosis. The authors concluded, inter alia, that there was very little contemporary evidence, meeting the Review's inclusion criteria, that evaluated the effectiveness of water fluoridation for the prevention of dental caries. The purpose of this critique is to examine the conduct of the above Review, and to put it into context in the wider body of evidence regarding the effectiveness of water fluoridation. While the overall conclusion that water fluoridation is effective in caries prevention agrees with previous reviews, many important public health questions could not be answered by the Review because of the restrictive criteria used to judge adequacy of study design and risk of bias. The potential benefits of using wider criteria in order to achieve a fuller understanding of the effectiveness of water fluoridation are discussed. PMID:27056513

    Full Text Available Abstract Background Dental caries in children is unevenly distributed within populations with a higher burden in low socio-economy groups. Thus, tools are needed to allocate resources and establish evidence-based programs that meet the needs of those at risk. The aim of the study was to apply a novel concept for presenting epidemiological data based on caries risk in the region of Halland in southwest Sweden, using geo-maps. Methods The study population consisted of 46,536 individuals between 3-19 years of age (75% of the eligible population from whom caries data were reported in 2010. Reported dmfs/DMFS>0 for an individual was considered as the primary caries outcome. Each study individual was geo-coded with respect to his/her residence parish. A parish-specific relative risk (RR was calculated as the observed-to-expected ratio, where the expected number of individuals with dmfs/DMFS>0 was obtained from the age- and sex-specific caries (dmfs/DMFS>0 rates for the total study population. Smoothed caries risk geo-maps, along with corresponding statistical certainty geo-maps, were produced by using the free software Rapid Inquiry Facility and the ESRI® ArcGIS system. Results The geo-maps of preschool children (3-6 years, schoolchildren (7-11 years and adolescents (12-19 years displayed obvious geographical variations in caries risk, albeit most marked among the preschoolers. Among the preschool children the smoothed relative risk (SmRR varied from 0.33 to 2.37 in different parishes. With increasing age, the contrasts seemed to diminish although the gross geographical risk pattern persisted also among the adolescents (SmRR range 0.75-1.20. Conclusion Geo-maps based on caries risk may provide a novel option to allocate resources and tailor supportive and preventive measures within regions with sections of the population with relatively high caries rates.

    Full Text Available ABSTRACT Tooth decay is one of the diseases most prevalent, being ranked as one of the major public health problems worldwide. For this reason it has been emphasized the development of new preventive methods, as the use of sugar-free gum. With this strategy it is possible to obtain significant benefits for oral health product by: (1 stimulation of salivation, which favors the clearance and regulates the pH; (2 promotion of remineralization as a consequence of this stimulation and the addition of minerals to the gum; (3 mechanical plaque control; (4 replacement of sugar with sweeteners harmful for bacteria, of which the most widely used is the xylitol; and (5 addition of active agents such as bicarbonate, casein, urea, chlorhexidine and chitosan, among others. Despite providing these benefits, is considered that the effect of gum is weak in preventing caries when the order is sought in the absence of toothbrushing and therefore should be proposed for implementation in addition to routine oral hygiene and not as a preventive measure alone, being necessary to perform a greater number of short and long term clinical trials to evaluate the effectiveness in a context of high biological variability, including patients of different sex, age, socioeconomic status and systemic health.

    Purpose We assessed the efficacy of supervised toothbrushing with xylitol toothpaste to prevent early childhood caries (ECC) and to reduce mutans streptococci (MS). Methods In this cluster-randomized efficacy trial, 4 Head Start classrooms in the Marshall Islands were randomly assigned to supervised toothbrushing with 1,400ppm/31% fluoride-xylitol (Epic Dental, Provo, UT) or 1,450ppm fluoride-sorbitol toothpaste (Colgate-Palmolive, New York, NY) (N=196 children, ages 4–5 yrs). We hypothesized no difference in efficacy between the two types of toothpaste. The primary outcome was primary molar d2-3mfs increment after 6 mos. A single examiner was blinded to classroom assignments. Two classrooms were assigned to the fluoride-xylitol group (85 children) and 2 classrooms to the fluoride-sorbitol group (83 children). The child-level analyses accounted for clustering. Results There was no difference between the two groups in baseline or end-of-trial mean d2-3mfs. The mean d2-3mfs increment was greater in the fluoride-xylitol group compared to the fluoride-sorbitol group (2.5 and 1.4 d2-3mfs, respectively), but the difference was not significant (95% CI:−0.17, 2.37;P=0.07). No adverse effects were reported. Conclusion After 6 mos, brushing with a low strength xylitol/fluoride toothpaste is no more efficacious in reducing ECC than a fluoride only toothpaste in a high caries risk child population.

    Full Text Available Abstract Background Supervised toothbrushing programs using fluoride dentifrice have reduced caries increment. However there is no information about the effectiveness of the professional cross-brushing technique within a community intervention. The aim was to assess if the bucco-lingual technique can increase the effectiveness of a school-based supervised toothbrushing program on preventing caries. Methods A randomized double-blinded controlled community intervention trial to be analyzed at an individual level was conducted in a Brazilian low-income fluoridated area. Six preschools were randomly assigned to the test and control groups and 284 five-year-old children presenting at least one permanent molar with emerged/sound occlusal surface participated. In control group, oral health education and dental plaque dying followed by toothbrushing with fluoride dentifrice supervised directly by a dental assistant, was developed four times per year. At the remaining school days the children brushed their teeth under indirect supervising of the teachers. In test group, children also underwent a professional cross-brushing on surfaces of first permanent molar rendered by a specially trained dental assistant five times per year. Enamel and dentin caries were recorded on buccal, occlusal and lingual surfaces of permanent molars during 18-month follow-up. Exposure time of surfaces was calculated and incidence density ratio was estimated using Poisson regression model. Results Difference of 21.6 lesions per 1,000 children between control and test groups was observed. Among boys whose caries risk was higher compared to girls, incidence density was 50% lower in test group (p = 0.016. Conclusion Modified program was effective among the boys. It is licit to project a relevant effect in a larger period suggesting in a broader population substantial reduction of dental care needs. Trial registration ISRCTN18548869.

    After radiation treatment of head-and-neck cancer, the impairment of patient's quality of life still remains an issue. After completion of the treatment course, a substantial number of patients develop so-called radiation caries. In addition, almost 50% of all cases of infectious osteoradionecrosis (iORN) of the jaws are directly associated with radiation caries. This review addresses our current knowledge on the etiology and pathogenesis of radiation caries including possible preventive strategies. Materials and methods A PubMed search using the terms ''radiation caries'' (''radiation related caries'', ''radiation related damage to dentition'') and ''radiogenic caries'' (''postradiation caries'', ''dental complications and radiotherapy'') was performed. The analysis of its content focused on the etiology, the pathogenesis, and the available knowledge on prophylaxis as well as treatment of radiation caries. Results For this review, 60 publications were selected. As main causal factors for radiogenic caries, either indirect impairment, resulting from alterations in the oral environment (e.g., radiation-induced xerostomia) or direct radiation-induced damage in teeth hard tissues are discussed. Radiation caries remains a lifelong threat and, therefore, requires permanent prevention programs. Conclusion To enable optimal medical care of the patients during the time course of radiotherapy as well as afterwards, close interdisciplinary cooperation between radiotherapists, oral surgeons, otorhinolaryngologists, and dentists is absolutely essential.

  20. Effects of the low-intensity laser therapy on the prevention of dental caries induced in rats

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the effects of low intensity laser therapy, associated or not to an acidulated phosphate fluoride, on the prevention of dental caries induced in rats. It was used 40 wistar rats, female, weaned with 18 days, fed with a cariogenic diet during 48 days and inoculated orally with Streptococcus mutans by three consecutive days starting from the second day of the diet. On the fifth day of experiment the animals were divided into five groups: Gc (control) the animas were no submitted to any treatment; GL (laser) irradiation with low power laser (GaAlAs, λ=660 nm, P=30 mW, Δt=5 sec, 5 J/cm2); GF (fluoride) topical application of acidulated phosphate fluoride (APF 1,23%) for four minutes; GLF (laser + fluoride) irradiation with low power laser followed by topical application of acidulated phosphate fluoride; GFL (fluoride + laser) topical application of acidulated phosphate fluoride followed by low power laser. The animals were sacrificed after 48 days; the molars were extracted and prepared to determine the dental caries lesions area by optical microscopy, enamel microhardness and analysis of the calcium and phosphorus ratio (Ca/P) by energy dispersive spectroscopy. The results were statistically analyzed by ANOVA (pLF was smaller than that for GF and GFL groups but no statistical difference was observed. There was no significant statistical difference between the microhardness of the GC and GL groups and among GFL, GLF and GF groups. Regarding to the calcium and phosphorus ratio, it was not observed significant statistical differences among the groups. These findings suggest that low-intensity laser radiation associated with acidulated phosphate fluoride reduces the caries area and could be an alternative in the prevention of the dental caries.

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 {mu}m, resulting in an energy density of 84,9 J/cm{sup 2}. The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

    Full Text Available Abstract Background Occlusal surfaces of erupting and newly erupted permanent molars are particularly susceptible to caries. The objective of the study was to assess and compare the effect of a single application of 38% SDF with ART sealants and no treatment in preventing dentinal (D3 caries lesions on occlusal surfaces of permanent first molars of school children who participated in a daily school-based toothbrushing program with fluoride toothpaste. Methods The prospective community clinical trial in the Philippines was conducted over a period of 18 months and included 704 six- to eight-year-old school children in eight public elementary schools with a daily school-based fluoride toothpaste brushing program. Children were randomly assigned for SDF application or ART sealant treatment. Children from two of the eight schools did not receive SDF or ART sealant treatment and served as controls. SDF or ART sealant treatment was applied on sound occlusal surfaces of permanent first molars. Surfaces that were originally defined as sound at baseline but which changed to dentinal (D3 caries lesions were defined as surfaces with new caries (caries increment. Non-compliance to the daily toothbrushing program in three schools offered the opportunity to analyze the caries preventive effect of SDF and sealants separately in fluoride toothpaste brushing and in non-toothbrushing children. Results In the brushing group, caries increment in the SDF treatment group was comparable with the non-treatment group but caries increment in the sealant group was lower than in the non-treatment group with a statistically significant lower hazard ratio of 0.12 (0.02-0.61. In the non-brushing group, caries increment in the SDF treatment group and the sealant group was lower than the non-treatment group but the hazard ratio was only statistically significant for the sealant group (HR 0.33; 0.20-0.54. Caries increment was lower in toothbrushing children than in non

    1993-01-01

    About 65% of the original 258 children who participated in 1982-1984 in a caries prevention program involving the use of xylitol chewing gum were retrieved in 1989 for a follow-up study. Ninety-five subjects from the original xylitol (X) group and 70 subjects from the original control (no-gum, C) group were available. In 1984, when the children completed the program at the age of 13-14 years, the caries scores were significantly lower in children who had used xylitol gums daily, compared with the C group. In 1989, 5 years after the discontinuation of the gum program, the difference between the X and C groups had continued to increase in favor of the X group. These effects were explained by assuming that the X gum program had facilitated the establishment of a low-virulent bacterial flora on the surfaces of the teeth, and especially on those teeth that erupted during the trial proper. This type of results are possibly helpful when evaluating cost-benefit ratios of caries prevention. PMID:8281565

    The aim of the study was to assess the relationship between the salivary mutans streptococci (SMS) level and the effectiveness of a preventive intervention based on a biannual application of an amine fluoride solution (AmF). A total of 284 schoolchildren aged 6 years were recruited from eleven classes of a primary school in Milan and randomly assigned to an experimental (A) and a control group (B). SMS counts were obtained at baseline and caries incidence data (diseased, missing, filled teeth, DMFT) were recorded every 6 months for 5 years. The participants of the experimental group received application of an AmF 1% F(-) solution twice a year on the enamel surfaces of the first permanent molars for 5 years. Control group subjects received application of a placebo solution twice a year on the enamel surfaces of the first molars for the same period. The mean DMFT in the experimental and control groups were 0.56 and 0.22, respectively, at the beginning and 1.14 and 2.06 after 5 years. SMS data allowed children to be classified into low- (0-10(5) CFU/ml of saliva) and high- (>10(5) CFU/ml of saliva) SMS subjects. Survival analysis, performed on the first molar data split by SMS group, showed a significantly higher caries reduction in low-SMS experimental group subjects compared to low-SMS control group subjects after 5 years. No significant differences were found between the two high-SMS experimental and control groups. These findings indicate that the preventive effects of the treatment were significantly lower in subjects who had high SMS. It is concluded that the effectiveness of a simple and economical topical fluoride intervention applicable at a community level is significantly influenced by the SMS level of the subjects involved. Simple AmF preventive interventions, applied on low-SMS subjects, can give significant results in terms of caries reduction. PMID:10529526

    The objective of this study was to estimate the caries impact of providing training in infant feeding guidelines to workers at Brazilian public primary care clinics. In a cluster-randomized controlled trial (n = 20 clinics), health care workers either were trained in guidelines for infant nutrition, stressing healthful complementary feeding, or were assigned to a 'usual practices' control, which allowed for maternal counseling at practitioner discretion. Training occurred once; the amount of counseling provided to mothers was not assessed. Eligible pregnant women were enrolled to follow health outcomes in their children. Early childhood caries (ECC) was measured at age three years (n = 458 children). The overall reductions in ECC (relative risk, 0.92; 95%CI, 0.75, 1.12) and severe ECC (RR, 0.87; 95%CI, 0.64, 1.19) were not statistically significant. There was a protective effect among mothers who remained exclusively at the same health center (S-ECC RR, 0.68; 95%CI, 0.47, 0.99) and among those naming the health center as their principal source of feeding advice (S-ECC RR, 0.53; 95%CI, 0.29, 0.97). Health care worker training did not yield a statistically significant reduction in caries overall, although caries was reduced among children of mothers more connected to their health centers.

    Full Text Available Dental caries is one of the most common childhood diseases, and people continue to be susceptible to it throughout their lives. Although dental caries can be arrested and potentially even reversed in its early stages, it is often not self-limiting and progresses without proper care until the tooth is destroyed. Early childhood caries (ECC is often complicated by inappropriate feeding practices and heavy infection with mutans streptococci. Such children should be targeted with a professional preventive program that includes oral hygiene instructions for mothers or caregivers, along with fluoride and diet counseling. However, these strategies alone are not sufficient to prevent dental caries in high-risk children; prevention of ECC also requires addressing the socioeconomic factors that face many families in which ECC is endemic. The aim of this paper is to systematically review information about ECC and to describe why many children are suffering from dental caries.

    Habitual xylitol gum-chewing may have a long-term preventive effect by reducing the caries risk for several years after the habitual chewing has ended. The goal of this report was (1) to determine if sorbitol and sorbitol/xylitol mixtures provide a long-term benefit, and (2) to determine which teeth benefit most from two-year habitual gum-chewing - those erupting before, during, or after habitual gum-chewing. Children, on average 6 years old, chewed gums sweetened with xylitol, sorbitol, or xylitol/sorbitol mixtures. There was a "no-gum" control group. Five years after the two-year program of habitual gum-chewing ended, 288 children were re-examined. Compared with the no-gum group, sorbitol gums had no significant long-term effect (relative risk [RR], 0.65; 95% confidence interval [c.i.], 0.39 to 1.07; p Xylitol gum and, to a lesser extent, xylitol/sorbitol gum had a long-term preventive effect. During the 5 years after habitual gum-chewing ended, xylitol gums reduced the caries risk 59% (RR, 0.41; 95% c.i., 0.23 to 0.75; p Xylitol-sorbitol gums reduced the caries risk 44% (RR, 0.56; 95% c.i., 0.36 to 0.89; p xylitol strongly depended on when teeth erupted (p xylitol gum-chewing should be started at least one year before permanent teeth erupt.

    2013-01-01

    Full Text Available Introduction: Study on the effect of topically applied mutanase on plaque formation and caries in rats showed strong inhibition of dental caries. Furthermore, it has been shown that the presence of mutanase in dental plaque may affect the synthesis and structure of sticky, extracellular glucans. The Hypothesis: Mutanase can be easily added to gum base. After chewing of mutanase-containing chewing gum, the enzyme will be released into the oral cavity. Mutanase will hydrolyze sticky, extracellular glucans, e.g., mutan inhibiting cariogenic bacteria to cohere/adhere and form plaque. Evaluation of the Hypothesis: The main challenge with this hypothesis is the source of mutanase. It can be obtained from Paenibacillus sp. MP-1 or Trichoderma harzianum F-340. Directly compressible medicated chewing gum bases can be used to avoid inactivation of mutanase during the manufacturing process.

    Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are aetiologically associated with the development of dental caries in humans and experimental animals. These organisms produce glucosyltransferases (GTases), which catalyse the synthesis of adherent glucan from sucrose, promoting the adherence of the organisms to the tooth surface. In addition, they release large quantities of acids from various dietary sugars. These are the essential virulence factors of mutans st...

    Lasers are used for several procedures involving hard and soft tissues of the oral cavity. Included in those procedures is the use of the CO2 laser to alter the surface structure of tooth enamel to render it more resistant to caries. A new 9.6micrometers wavelength TEA CO2 laser (Argu Photonics, Jpiter, FL) has been investigated as a device that can be used for this procedure without harming the dental pulp. Erupted, caries and restoration free third molars (n=24) were used in the experiment. Teeth were irradiated at an incident fluence of 1.5J/cm2 and a repetition rate of 10Hz and a spot size 1mm in diameter. At the low and high settings, 200 to 400 pulses were delivered at 12mJ per pulse for a total energy of 2.4 or 4.8J delivered for 20 or 40 seconds respectively. Other teeth were subjected to a sham dental procedure (positive control) or no procedure (negative control). Prior to testing, radiographs were taken of all teeth, and they were tested pulpally using heat, cold and electricity to determine vitality. The teeth were removed either immediately or at one week or one month after testing. They were bioprepared and examined histologically for signs of inflammation. Only one tooth developed symptoms of sensitivity to cold for 10 days following exposure to the high power level. The sensitivity was of fleeting duration and was judged to be reversible pulpitis. All teeth tested responded normally at pretesting and pre-extraction time periods. Histological examination disclosed no indication of an inflammatory response in the pulp tissue. All sections appeared normal with no changes seen in the normal pulpal morphology. We conclude that the 9.6 micrometers wavelength laser causes no pulpal damage at the energy levels used and can be used safely for caries prevention treatments.

    Full Text Available Abstract Background Early Childhood Caries (ECC is a widespread problem in Australian Aboriginal communities causing severe pain and sepsis. In addition dental services are difficult to access for many Aboriginal children and trying to obtain care can be stressful for the parents. The control of dental caries has been identified as a key indictor in the reduction of Indigenous disadvantage. Thus, there is a need for new approaches to prevent ECC, which reflect the cultural norms of Aboriginal communities. Methods/Design This is a Phase II single arm trial designed to gather information on the effectiveness of a dental health education program for Aboriginal children aged 6 months, followed over 2 years. The program will deliver advice from Aboriginal Health Workers on tooth brushing, diet and the use of fluoride toothpaste to Aboriginal families. Six waves of data collection will be conducted to enable estimates of change in parental knowledge and their views on the acceptability of the program. The Aboriginal Health Workers will also be interviewed to record their views on the acceptability and program feasibility. Clinical data on the child participants will be recorded when they are 30 months old and compared with a reference population of similar children when the study began. Latent variable modeling will be used to interpret the intervention effects on disease outcome. Discussion The research project will identify barriers to the implementation of a family centered Aboriginal oral health strategy, as well as the development of evidence to assist in the planning of a Phase III cluster randomized study.

    2013-07-01

    Full Text Available 72 1024x768 Various studies stated that the increase concentration of fluoride in toothpastes leads to the reduction of calcium loss in enamel. Objective: The purpose of this study was to test the difference between the effect of 1300ppm fluoride with carrageenan toothpaste and 1000ppm fluoride only toothpaste on roughness and hardness of enamel surface. Methods: Enamel specimens were obtained from 30 extracted human premolars. The enamel specimens were randomly assigned to one of the three groups, 1300ppm fluoride with carrageenan toothpaste, 1000ppm fluoride only toothpaste and toothpaste with no fluoride as a negative control. The samples were immersed in 1% citric acid with pH 4 for 150 seconds for demineralization, afterwards exposed to each toothpaste for 6 minutes. Results: The results demonstrated that toothpaste with 1300ppm fluoride with carregeenan has two times greater efficacy in triggering remineralization than toothpaste with 1000ppm fluoride only, with regards to surface roughness and hardness recovery in an in vitro caries model. Conclusion: The results suggested that treatment of enamel with toothpaste containing 1300ppm fluoride with carrageenan has high potential in inducing remineralization on enamel.DOI: 10.14693/jdi.v20i1.125

    The purpose of this study was to investigate the effects of low intensity laser therapy, associated or not to an acidulated phosphate fluoride, on the prevention of dental caries induced in rats. It was used 40 wistar rats, female, weaned with 18 days, fed with a cariogenic diet during 48 days and inoculated orally with Streptococcus mutans by three consecutive days starting from the second day of the diet. On the fifth day of experiment the animals were divided into five groups: G{sub c} (control) the animas were no submitted to any treatment; G{sub L} (laser) irradiation with low power laser (GaAlAs, {lambda}=660 nm, P=30 mW, {delta}t=5 sec, 5 J/cm{sup 2}); G{sub F} (fluoride) topical application of acidulated phosphate fluoride (APF 1,23%) for four minutes; G{sub LF} (laser + fluoride) irradiation with low power laser followed by topical application of acidulated phosphate fluoride; G{sub FL} (fluoride + laser) topical application of acidulated phosphate fluoride followed by low power laser. The animals were sacrificed after 48 days; the molars were extracted and prepared to determine the dental caries lesions area by optical microscopy, enamel microhardness and analysis of the calcium and phosphorus ratio (Ca/P) by energy dispersive spectroscopy. The results were statistically analyzed by ANOVA (pcaries areas for the group G{sub LF} was smaller than that for G{sub F} and G{sub FL} groups but no statistical difference was observed. There was no significant statistical difference between the microhardness of the G{sub C} and G{sub L} groups and among G{sub FL}, G{sub LF} and G{sub F} groups. Regarding to the calcium and phosphorus ratio, it was not observed significant statistical differences among the groups. These findings suggest that low-intensity laser radiation associated with acidulated phosphate fluoride reduces the caries area and could be an alternative in the prevention of the dental caries.

    Recent increases in caries prevalence in young children throughout the world highlight the need for a simple but effective infant oral care programme. This programme needs to include a medical disease prevention management model with an early establishment of a dental home and a treatment approach based on individual patient risk. This article presents an updated approach with practical forms and tools based on the principles of caries management by risk assessment, CAMBRA. This method will aid the general practitioner to develop and maintain a comprehensive protocol adequate for infant and young children oral care visits. Perinatal oral health is vitally important in preventing early childhood caries (ECC) in young children. Providing dental treatment to expectant mothers and their young children in a 'dual parallel track' is an effective innovative strategy and an efficient practice builder. It promotes prevention rather than intervention, and this may be the best way to achieve long-lasting oral health for young patients. General dental practice can adopt easy protocols that will promote early preventive visits and anticipatory guidance/counselling rather than waiting for the need for restorative treatment.

    The program of chemical preventive dentistry is based primarily upon the development of a procedure for stabilizing stannous fluoride in solution by forcing it into glycerin. New topical fluoride treatment concentrates, fluoride containing gels and prophylaxis pastes, as well as a completely stable stannous fluoride dentifrice are made possible by the development of a rather complicated heat application method to force stannous fluoride into solution in glycerin. That the stannous fluoride is clinically effective in such a preparation is demonstrated briefly on orthodontic patients.

    Full Text Available Objective. This study explores the challenges faced by the research implementation team in engaging new mothers in a community oral health prevention intervention in an American Indian (AI reservation community. Methods. Qualitative methods in the form of in-depth interviews were used in the study. Qualitative data were collected from research staff workers at a field site, who were involved in the implementation of a culturally tailored, randomized controlled trial of a behavioral intervention utilizing Motivational Interviewing (MI. Results. Several challenges were described by the field staff in engaging new mothers, including low priority placed on oral health, lack of knowledge, and distractions that reduced their ability to engage in learning about oral health of their child. Other difficulties faced in engaging the mothers and the AI community at large were distrust related to racial differences and physical and environmental barriers including poor road conditions, lack of transportation and communication, and remoteness of data collection sites. The field staff developed and applied many strategies, including conducting home visits, applying new communication strategies, and interacting with the community at various venues. Conclusion. Prevention interventions for ECC need to target AI mothers. Strategies developed by the field staff were successful for engaging mothers in the study.

    Caries prevention is a goal to be achieved by dentist in order to promote health. There are several methods used to detect dental caries each one presenting advantages and disadvantages, especially regarding hidden occlusal caries. The improvement of laser technology has permitted the use of laser fluorescence for early diagnosis of hidden occlusal caries. The aim of this study was to assess the efficacy of the use of 655 nm laser light on the detection of hidden occlusal caries. Forty molar teeth from patients of both sexes which ages ranging from 10 - 18 years old were used on this study. Following manufacture's instructions regarding the use of the equipment, the teeth had their occlusal surface examined with the DIAGNOdent. Twenty six of 40 teeth had hidden occlusal caries detected by the DIAGNOdent. However only 17 of these 26 teeth showed radiographic signs of caries the other 9 teeth showed no radiological signs of the lesion. Radiographic examination was able to identify 34,61% of false negative cases. This means that many caries would be left untreated due to the lack of diagnosis using both visual and radiographic examination. The use of the DIAGNOdent was effective in successfully detecting hidden occlusal caries.

    This study was conducted to determine the effect of Q-Switched Nd: YAG laser energy dose to human enamel caries. The specifications of Q-Switched Nd: YAG laser as followed: wavelength of 1064 nm and 6 ns pulse width. Caries enamel samples taken from human teeth molars of 17-35 ages and the type of media caries. Energy doses used in this study were 723.65 mJ/cm2, 767.72 mJ/cm2, and 1065.515 mJ/cm2; 5 Hz repetition rate, and 20 second exposure time. Samples characterized the surface morphology and the percentage of constituent elements, especially calcium/phosphorus (Ca/P) with FESEM-EDAX. The fraction volume and crystallinity percentage of hydroxyapatite (HA) with XRD and hardness value using Vickers Microhardness Test. The results indicated that exposure of Q-Switched Nd:YAG laser on enamel caries resulting cracks, holes, and melt due to plasma production effects in the surface. Plasma production effect also resulted in micro properties such as percentage of Ca/P was close to normal, the fraction volume and crystallinity percentage of HA went up but did not change the crystal structure (in terms of the lattice structure). The hardness value also rose as linear as exposure energy dose caused by phototermal effect. Based on the results, Q-Switched Nd:YAG laser can be used as contactless drill dental caries replacement candidate with the additional therapy effect such as localized caries in order to avoid the spread, the ratio of Ca/P approaching healthy teeth, the fraction volume and crystallinity percentage of HA rose and established stronger teeth with peak energy dose 1065.515 mJ/cm2.

  9. The relationship between diet and Dental Caries

    International Nuclear Information System (INIS)

    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.

    using complementary methods for its control. Pit and fissures sealants represent one of the most effective preventive interventions in dentistry, being considered as a contribution to the public health interventions. Nevertheless, there are no consistent evidences about their true effectiveness and impact in the prevention of caries. These inconsistencies could be due to the presence of bias or the heterogeneity of the studies available in literature. Thus, we propose to make a review with the aim to evaluate the methodological quality of clinical trials using pit and fissure sealants. A search of studies between 1990 and 2012 was conducted and 18 clinical trials that fulfilled the inclusion and exclusion criteria were found. The studies included were obtained and evaluated by a single reviewer. This review concludes that the evidence that guarantees the use of this intervention is methodologically poor. These findings may stimulate the professionals to clarify the truth referring to the effectiveness of sealants, before applying it indiscriminately. The accomplishment of new clinical trials executed with an appropriate methodological design and statistical analysis is recommended, generating reliable results for the decision making that guides the Public Health Policies.

    2013-11-01

    Full Text Available Dental caries is a multifactorial disease that affects most populations throughout the world and it is still the primary cause of oral pain and tooth loss. The occlusal surfaces of posterior teeth are the most vulnerable sites for dental caries due to their anatomy. Therefore, the aim of the following article is to summarize current knowledge on occlusal caries development and the possibilities of its prevention. Although the overall caries rate today has fallen for populations in industrialized countries, the rate of occlusal surface caries has not decreased. This may be explained with fact that topically applied fluorides and their mode of action prevent caries better on smooth than on occlusal surfaces. As we know, tooth decay of first permanent molars causes a great deal of different short and long term difficulties for patients. Therefore, there is a continuous need for implementation of programs for caries prevention in permanent teeth. Nowadays, we like to treat our patients by minimally invasive methods. A very important step in our effective preventive treatment is sealing pits and fissures as a cornerstone of occlusal caries management. Reliable assessment of caries activity is also very important for defining treatment needs and plans. A very important decision, which should be made during occlusal caries management, is the selection of restorative material according to the treatment plan. Conclusion. Current possibilities in occlusal caries prevention and management are very effective. Therefore, dentists today do not have any excuse for avoiding the philosophy of Minimally Invasive Dentistry, especially when we talk about caries management of occlusal surfaces in permanent molars.

Objective - in vitro study of changes of just erupted permanent teeth enamel surface under the influence of exogenous means for caries prevention containing different calcium compounds. Methods. For the study we used 35 enamel samples of permanent teeth that had erupted within the same term (premolars of 11-13 years old children, less than 6 months after eruption. 5 samples were the control group before the experiment. 30 samples were randomly divided equally into three groups (10 samples in each group and stored in boxes with artificial saliva. Enamel samples of the first group were treated with cream “TOOTH MOUSSE” (10% casein phosphopeptide - amorphous calcium phosphate, samples of the second group were treated with gel “R.O.C.S.® Medical minerals” (calcium glycerophosphate, magnesium chloride, xylitol. Samples of the first and second groups were treated at the beginning of the research and 3, 6 and 9 months later during 10 days, twice a day for 30 minutes. Samples of the third group were the control and were not treated. Investigation of the enamel surface was performed at the beginning of the experiment, after 6 and 12 months. The structure of the samples surface was studied at the equator zone with the scanning electron microscope. Results. At the beginning of the experiment signs of insufficient mineralization were observed on the surface of the enamel samples of the control group. After 12 months of treatment with cream with casein phosphopeptide - amorphous calcium phosphate and gel with calcium glycerophosphate, surface of the enamel samples of both groups had the signs of an increased mineralization due to the long-term preservation of a layer of additional chemical compounds. Conclusion. The surface of the permanent teeth enamel immediately

  3. Promoting oral health: interventions for preventing dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries. A report on recommendations of the task force on community preventive services.

    Science.gov (United States)

    2001-11-30

    The Task Force on Community Preventive Services (the Task Force) has conducted systematic reviews of the evidence of effectiveness of selected population-based interventions to prevent and control dental caries (tooth decay), oral (mouth) and pharyngeal (throat) cancers, and sports-related craniofacial injuries. The Task Force strongly recommends community water fluoridation and school-based or school-linked pit and fissure sealant delivery programs for prevention and control of dental caries. Using the rules of evidence it has established, the Task Force found insufficient evidence of effectiveness or ineffectiveness of the remaining interventions reviewed. Therefore, the Task Force makes no recommendation for or against use of statewide or communitywide sealant promotion programs, population-based interventions for early detection of precancers and cancers, or population-based interventions to encourage use of helmets, facemasks, and mouthguards to reduce oral-facial trauma in contact sports. The Task Force's finding of insufficient evidence indicates the need for more research on intervention effectiveness. Until the results of such research become available, readers are encouraged to judge the usefulness of these interventions by other criteria. This report presents additional information regarding the recommendations, briefly describes how the reviews were conducted, and provides information designed to help apply the strongly recommended interventions locally.

  4. Health promotion and dental caries

    Directory of Open Access Journals (Sweden)

    Marisa Maltz

    2010-01-01

    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.

    Full Text Available Abstract Despite remarkable reduction in the prevalence of dental caries in the United States, dental caries is still a highly prevalent disease among children who are socially disadvantaged (racial/ethnic minority, poor, rural, immigrants. Consequently, caries sequelae such as dental pain, need for dental treatment under general anesthesia, and future orthodontic treatment, are also concentrated among the most socially disadvantaged children. To make the situation more appalling, those children who need treatment the most are the ones least likely to visit the dentist. Low income children are less likely to visit the dentist in part because of family's competing needs for limited resources, shortage of pediatric dentists, and dentists not taking uninsured or publicly insured patients. In the same vein, if these children do not have access to dental care, they are deprived from effective caries preventive measures that are dentist-dependent such as sealants and professionally applied fluoride. Dentistry has done well at devising caries preventive and treatment strategies; but these strategies have missed the most needed segment of society: disadvantaged children. The challenge now is to develop innovative strategies to reach these children.

    The purpose of this study was to assess the relationship between vitamin D status and dental caries in Canadian school-aged children participating in the Canadian Health Measures Survey (CHMS). The CHMS was a national cross-sectional study involving physical assessments, laboratory analysis, and interviews. Analysis was restricted to data for 1,017 children 6 to 11 y of age. Outcome variables included the presence of caries and overall total caries score (dmft/DMFT index). Levels of 25-hydroxyvitamin D (25(OH)D) were measured from serum samples obtained from participants. Bivariate analysis, logistic regression for the presence of caries, and multiple linear regression for total caries scores were used. Significance was set at P ≤ 0.05. Overall, 56.4% of children experienced caries, and the mean dmft/DMFT score was 2.47 (95% CI 2.09 to 2.84). The unadjusted odds of children with 25(OH)D levels ≥75 nmol/L having experienced caries was 0.57 (95% CI 0.39 to 0.82), while the odds for caries at the ≥50 nmol/L level was 0.56 (95% CI 0.39 to 0.89). After controlling for other covariates, backward logistic regression revealed that the presence of caries was significantly associated with 25(OH) levels caries scores were also associated with 25(OH)D concentrations caries and lower serum vitamin D. Improving children's vitamin D status may be an additional preventive consideration to lower the risk for caries. PMID:26553883

En este artículo se analiza el estado del conocimiento y la evidencia científica sobre este tema.The treatment of deep dentine carious lesions in permanent teeth has included, generally, complete removal of affected dentin in a single session, including soft demineralized dentin, regardless of the regenerative potential of dental pulp. One complication often linked to this attitude is the pulp exposure, in many cases ending in root canal treatment. Several studies have shown that the elimination of deep dentine caries in stages, in two visits to several months apart, protects the pulp, reducing the frequency of pulp exposures, while allowing the development of tertiary dentin, with the consequent decrease in the percentage of cases requiring endodontic treatment. This article discusses the state of knowledge and scientific evidence on this topic.

    Full Text Available Dental disease can have devas-tating effects on children who lack access to dental care. The US was shocked to learn of the recent death of a child from a caries related infection. The bio-logical basis of dental caries risk is usually considered interims of individual behavior. The role of the family and other more complex units of social organization in determining caries risk are not often appreciated. The transmission of caries causing bacteria from mothers (or other care givers having extensive contact with the child has been well docu-mented. In addition the age at which children are vulnerable to colonization with caries causing organisms is known. Despite the fact that the dental and scientific communities possess knowledge concerning the routs of caries transmission, efforts to implement preventive programs specifically targeting the reduction of caries transmission have been inconsistent. Working with and motivating families to prevent caries transmission should be the shared objective of researchers and clinicians. Armed with the available know-ledge, caries should not the thought of as an inevitable part of life. The goal of this essay is to challenge readers to empower people at risk to make decisions that enable them to break the chain of caries infection.

    Remineralization of minor enamel defects is a normal physiological process that is well known to clinicians and researchers in dentistry and oral biology. This process can be facilitated by various dietary and oral hygiene procedures and may also concern dentin caries lesions. Dental caries is reversible if detected and treated sufficiently early. Habitual use of xylitol, a sugar alcohol of the pentitol type, can be associated with significant reduction in caries incidence and with tooth remineralization. Other dietary polyols that can remarkably lower the incidence of caries include erythritol which is a tetritol-type alditol. Based on known molecular parameters of simple dietary alditols, it is conceivable to predict that their efficacy in caries prevention will follow the homologous series, that is, that the number of OH-groups present in the alditol molecule will determine the efficacy as follows: erythritol >/= xylitol > sorbitol. The possible difference between erythritol and xylitol must be confirmed in future clinical trials. PMID:20339492

    2000-01-01

    This work was carried out as part of a community development project in North-West Haiti. The aim was to determine the prevalence of dental caries among young Haitians and to identify the principal determinants and risk factors. A total of 322 schoolchildren, all aged 12 years, participated in the study in March and April 1996. Demographic characteristics, hygiene and dietary habits were recorded. In parallel, a dentist assessed the amount of debris present on the teeth and investigated the children's history of caries. Almost two thirds of the children examined were free of caries. The mean number of decayed missing and filled teeth (DMFT index) was 0.93, which is low. However, a high-risk group was identified with a mean DMFT index of 3.8. This group is a source of some concern, particularly as the region's health services are often inaccessible resulting in dental caries frequently remaining untreated until tooth extraction is required. Logistic regression analysis showed that dental hygiene and, to a lesser extent, sugar intake, were the principal risk factors for dental caries. Adolescents who consume more than three meals per day and who, presumably, have a higher intake of cariogenic food, present more caries than those who consume less. These schoolchildren meet the objectives of the WHO for dental caries for 2000, but two courses of action are nonetheless necessary: caries prevention and improved access to dental health care. To prevent caries, techniques for increasing the resistance of teeth could be recommended, as in industrialized countries. However, such strategies would be difficult to implement in the rural context of a developing country. The addition of fluoride to drinking water, for example, is not practical as most of the inhabitants of rural areas do not have access to running water. The use of sealing agents, which protect against decay affecting the occlusal surfaces of molars, is also impractical, for financial reasons. Thus, basic

    Dental caries is one of the most common childhood diseases, and people continue to be susceptible to it throughout their lives. Although dental caries can be arrested and potentially even reversed in its early stages, it is often not self-limiting and progresses without proper care until the tooth is destroyed. Early childhood caries (ECC) is often complicated by inappropriate feeding practices and heavy infection with mutans streptococci. Such children should be targeted with a professional ...

    Full Text Available Objective. The aim of this research was to assess the efficiency of different multifactor models in caries prediction. Material and methods. Data from the questionnaire and objective examination of 109 examinees was entered into the Cariogram, Previser and Caries-Risk Assessment Tool (CAT multifactor risk assessment models. Caries risk was assessed with the help of all three models for each patient, classifying them as low, medium or high-risk patients. The development of new caries lesions over a period of three years [Decay Missing Filled Tooth (DMFT increment = difference between Decay Missing Filled Tooth Surface (DMFTS index at baseline and follow up], provided for examination of the predictive capacity concerning different multifactor models. Results. The data gathered showed that different multifactor risk assessment models give significantly different results (Friedman test: Chi square = 100.073, p=0.000. Cariogram is the model which identified the majority of examinees as medium risk patients (70%. The other two models were more radical in risk assessment, giving more unfavorable risk –profiles for patients. In only 12% of the patients did the three multifactor models assess the risk in the same way. Previser and CAT gave the same results in 63% of cases – the Wilcoxon test showed that there is no statistically significant difference in caries risk assessment between these two models (Z = -1.805, p=0.071. Conclusions. Evaluation of three different multifactor caries risk assessment models (Cariogram, PreViser and CAT showed that only the Cariogram can successfully predict new caries development in 12-year-old Bosnian children.

    Introduction Despite overall improvements in oral health, the number of children admitted to hospital for extraction of teeth due to caries under general anaesthesia (GA) has been reported as increasing dramatically in England. The new UK government plans to transform NHS dentistry by improving oral health.Aim To evaluate the dental care received by children who required caries-related extractions under GA and obtain the views of their parents or guardians on their experiences of oral health services and the support they would like to improve their child's oral health, to inform future planning.Method An interview questionnaire was designed and piloted to collect data from a consecutive sample of 100 parents or guardians during their child's pre-operative assessment appointment. This took place at one London dental hospital between November 2009 and February 2010.Results Most children were either white (43%) or black British (41%); the average age was seven years (range 2-15, SD 3.1, SE 0.31) and the female:male ratio was 6:5. Most (84%) had experienced dental pain and 66% were referred by a general dental practitioner (GDP). A large proportion of parents or guardians (47%) reported previous dental treatment under GA in their children or child's sibling/s. Challenges discussed by parents in supporting their child's oral health included parenting skills, child behaviour, peer pressure, insufficient time, the dental system and no plans for continuing care for their child. Three out of four parents (74%) reported that they would like support for their child's oral health. Sixty percent of all parents supported school/nursery programmes and 55% supported an oral health programme during their pre-assessment clinic.Discussion These findings suggest that the oral health support received by high caries risk children is low. Health promotion programmes tailored to this cohort are necessary and our findings suggest that they would be welcomed by parents. PMID:21508990

    Caries is one of the most common infectious diseases in the world. Dental caries can be defined as destruction of the tissues of the tooth by bacterial fermentation of dietary carbohydrates. In this respect, some bacteria are considered more caries-promoting than others, as an example Streptococcus mutans. A common feature for caries-promoting bacteria is that they are acidogenic and aciduric. The most common bacteria used as probiotics, lactobacilli and bifidobacteria, are, in theory, caries...

  2. Radiation caries - an evil eye of radiotherapy

    International Nuclear Information System (INIS)

    Although radiotherapy plays an important role in the management of patients with head and neck cancer, it is also associated with several undesired side effects such as radiation caries which is a common, yet serious, complication. The radiotherapy field of exposure frequently includes the salivary glands, oral mucosa, and jaws, thus, leading to various side effects including hyposalivation, mucositis, and taste loss. Irradiated patients are also at increased risk for the development of a rapid, rampant carious process known as radiation caries. Lesions tend to develop four weeks after completion of radiotherapy and affect atypical areas of teeth, such as the lingual surface, incisal edges, and cusp tips. The aim of this paper is to review the clinical features, prevention and management of radiation caries. (author)

    Dental caries, the most chronic disease affecting mankind, has been in the limelight with regard to its prevention and treatment. 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. This paper throws light on the role and effects of various forms of xylitol on dental caries and oral hygiene status of an individual. PMID:25422590

  10. Preventive maintenance basis: Project overview report update. Final report

    International Nuclear Information System (INIS)

    Preventive maintenance (PM) programs in US nuclear plants have evolved from strict compliance with the vendor's general recommendations which are likely to be conservative, to more flexible tasks which are intended to accommodate the plant service conditions. These PM programs have evolved piecemeal from the vendor recommendations and historical experience, with the result that their logical structure and coherent basis may be technically weak and scarcely recognized. The historical reasons for the performance of specific PM tasks are usually poorly documented, if at all. The result is that relationships and dependencies between the tasks, their limits of applicability and justifications for task intervals, are not well known. Utilities have expressed the desire for a technical basis and rationale capable of supporting the maintenance tasks for each major component type and of facilitating appropriate changes to them. The PM Basis project provides the utility user with the technical basis for PM tasks and task intervals and also gives the necessary information to adapt the tasks and intervals to plant conditions. A recommended program of PM tasks, a synopsis of the task content and intervals, and the reasons why these choices are technically valid in a variety of circumstances, are presented for 39 major component types. Each component type is treated in a separate volume of this series. This project overview report presents the project objectives and organization, describes the content, interpretation, and use of the PM Basis database, and explains the process by which the information was obtained

    Résults are presented from the "belgian heart disease prevention project, part of the WHO european collaborative trial in the multifactorial prevention of coronary heart disease (CHD)". 19.409 men aged 40-59 yr took part; they were employed in thirty factories which formed the allocation units for a randomised controlled trial lasting 5-6 yr. The intervention package consisted largely of health education promoting a cholesterol-lowering diet, smoking cessation, weight control, physical activity, and treatment of arterial hypertension. A programme of information was supplemented by face-to-face counselling at the workplace by two physicians attached to the project. The coronary risk profile was reduced in the intervention group, compared with that in the control group, especially during the first 4 yr, by effects on serum cholesterol, number of cigarettes smoked daily, and arterial blood-pressure. Total mortality was 17.5% lower in the intervention group than in the control group (p = 0.038); coronary mortality was reduced by a non-significant 20.8% whereas CHD incidence (non-fatal myocardial infarction plus fatal myocardial infarction plus sudden deaths) was reduced by 24.5%, (P = 0.031). Non-fatal myocardial infarction (not a major end-point) was similarly reduced by 26.1% (p = 0.030). PMID:2679938

The salivary samples were collected for ST and LBC and plaque samples were collected for Cariostat. Caries activity was assessed. Results: The data obtained were analyzed for sensitivity, specificity, positive predictive value, negative predictive value and over all accuracy. Conclusions: Our present study showed that the LBC was found to have a higher correlation in caries as the caries increased the count also increased with positive caries activity. A good correlation was found between Snyder and LBC for the caries activity 1, 2 and 3. But no correlation was seen for score 0. To conclude, a combination of all these tests was found to be good for assessing caries risk groups.

    Dental caries (tooth decay) continues to be a major problems for adults as well as children, even though great advances have been made in preventive methods in the last 20 years. New methods for the management of caries will work best if lesions can be detected at an early stage and chemical rather than physical intervention can take place, thereby preserving the natural tooth structure and helping the saliva to heal, or remineralize, the areas of early decay. Clinical detection of caries in the US relies on visual examination, tactile with hand held explorer, and conventional radiographs, all of which are inadequate for the occlusal (biting) surfaces of the teeth where most of the decay now occurs. The dentist often has to explore by drilling with a dental bur to confirm early decay in these areas. New method that can determine the extent and degree of subsurface lesions in these surfaces non-destructively are essential for further advances in the clinical management of dental caries. Optical methods, which exploit the differences between sound and carious enamel and dentin, show great promise for the accurate detection of these lesions. Two or three- dimensional images, which include a measure of severity will be needed.

    Dental caries is the most common oral disease with high incidence, widely spread and can seriously affect the health of oral cavity and the whole body. Current caries prevention measures such as fluoride treatment, antimicrobial agents, and traditional Chinese herbal, have limitations to some extent. Here we design and synthesize a novel peptide based on the amelogenin, and assess its ability to promote the remineralization of initial enamel caries lesions. We used enamel blocks to form initial lesions, and then subjected to 12-day pH cycling in the presence of peptide, NaF and HEPES buffer. Enamel treated with peptide or NaF had shallower, narrower lesions, thicker remineralized surfaces and less mineral loss than enamel treated with HEPES. This peptide can promote the remineralization of initial enamel caries and inhibit the progress of caries. It is a promising anti-caries agent with various research prospects and practical application value.

  11. Caries detection in dental radiographs

    International Nuclear Information System (INIS)

    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

    Full Text Available Dental caries is an infectious, communicable disease, which causes destruction of teeth by acid-forming bacteria found in dental plaque. Caries progression or reversal is determined by the balance between protective and pathological factors in the mouth. There have been revolutions in every field and dentistry is no exception to it, these changes have led to a change in concept from the conventional surgical approach of removing dental decay and cutting of tooth structure to the medical model which deals with interception of disease at different stages and possible reversal of the disease process. The key to medical paradigm is determination of caries risk in an individual and effective early detection of initial carious lesions. There are various equipments available in market which uses different principles for diagnosing caries susceptibility in an individual. In the years of thorough research different agents have been investigated for their role in caries prevention and reversal. There is a separate treatment plan for managing patients falling in different risk category. This article outlines the need for the medical management of dental caries and how it can be a viable option in dental decay management.

    Candida spp. are frequently detected in the mouths of children with extensive caries lesions compared with caries-free subjects. In this study we evaluated the presence of Candida spp. in association with mutans streptococci and lactobacilli in the saliva of children with dental decay, before and after anti-caries treatment. Samples of saliva from 14 children with caries lesions and from 13 caries-free subjects were evaluated for the presence of mutans streptococci, lactobacilli and Candida spp. by culture. Eleven of 14 carious subjects hosted Candida spp. in their saliva as against only 2 out of 13 subjects without caries lesions. Carious subjects were treated by adopting a conventional protocol for caries disease (rinses with a mouthwash containing 0.2% chlorhexidine and fluorine). After treatment, the salivary bacterial counts decreased for mutans streptococci and in some cases for lactobacilli, but large numbers of Candida spp. remained in the saliva of several children. The latter were treated with the antifungal drug nystatin (oral rinses) and evaluation of the level of yeasts in the saliva showed disappearance of the microorganism in several cases. The results indicate that antiseptic treatment alone for dental decay is not sufficient for the eradication of microorganisms potentially responsible for caries lesions, in particular when yeasts are present. We hypothesize that the oral cavity of children could act as a reservoir of fungi, and eradication could be needed to prevent both exacerbation of caries lesions, and colonization by Candida spp. of other host sites.

  4. Sugars and Dental Caries: Evidence for Setting a Recommended Threshold for Intake.

    Moynihan, Paula

    2016-01-01

    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

    Edgar, W M; Higham, S M

    The crucial role played by the actions of saliva in controlling the equilibrium between de- and remineralization in a cariogenic environment is demonstrated by the effects on caries incidence of salivary dysfunction and by the distribution of sites of caries predilection to those were salivary effects are restricted. However, of the several properties of saliva which may confer protective effects, it is not certain which are most important. A distinction can be made between static protective effects, which act continuously, and dynamic effects, which act during the time-course of the Stephan curve. Evidence implicates salivary buffering and sugar clearance as important dynamic effects of saliva to prevent demineralization; of these, the buffering of plaque acids may predominate. Enhanced remineralization of white spot lesions may also be regarded as dynamic protective effects of saliva. Fluoride in saliva (from dentifrices, ingesta, etc.) may promote remineralization and (especially fluoride in plaque) inhibit demineralization. The design of experiments using caries models must take into account the static and dynamic effects of saliva. Some models admit a full expression of these effects, while others may exclude them, restricting the range of investigations possible. The possibility is raised that protective effects of saliva and therapeutic agents may act cooperatively. PMID:8615945

  6. New method to detect caries via fluorescence

    Caries, a common and widespread infectious disease, has to be detected as early as possible. Based on the need for an easy and handy tool for preventing invasive treatment a new fluorescence camera system has been developed. Using this camera the so-called porphyrins, metabolic products of oral pathogenic bacteria can be visualized. Thereby fluorophores are excited at a wavelength of 405nm by the built-in GaN-LEDs. Healthy and diseased dental hard tissues fluoresce in the green and in the red spectral range, respectively, thus allowing differentiation by coulor. To prove the reliability of this fluorescence camera system, freshly extracted teeth were examined. Three different methods of analysis were verified and compared to give information about the lesions (sensitivity & selectivity): The extent of the fluorescence area, the integral of the red/green ratio of the lesion and the maximum red/green ratio in the area of interest. Histological sections of the teeth served as reference. In addition, the camera was compared to a tip probe sensor already available on the market. In total, our results show that regarding the three different algorithms of analysis, the maximum of the red/green ratio is a preferential method to evaluate carious lesions. Sound tissue, enamel caries and dentin caries can be clearly distinguished. The new fluorescence camera is a handy, efficient and fast device in order to detect lesions and seems to be superior to the tip probe sensor regarding the positioning. Further studies are required.

    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.

    The purpose of this presentation is to relay the experience of the Office of New Production Reactors (NP) in developing and implementing its pollution prevention program. NP was established to plan, design, and construct a new safe and environmentally acceptable nuclear reactor capacity necessary to provide an assured supply of tritium to maintain the nation`s long-term deterrent capability. The Program offered the Department of Energy an opportunity to demonstrate its commitment to environmental protection via minimization of environmental releases; new design offers the best opportunity for pollution prevention. The NP pollution prevention program was never fully implemented because NP`s tritium production design activity was recovery terminated. The information in this paper represented lessons learned from the last three years of NP operation.

    Objectives: To determine the prevalence of dental caries, and associated social risk factors among preschool children in Riyadh, Saudi Arabia. Methods: The study consisted of a random sample of 3 to 5 years- old preschool children who were examined in Riyadh, Saudi Arabia; 388 children (184 boys and 204 girls) were examined from 10 different preschools. Each surface of their teeth was examined for dental caries utilizing modified WHO criteria (WHO, 1997). Data information about age, gender and social factors status were obtained by questionnaires that had been answered by parents. Results: About 69% of children had dental caries with dmft score of 3.4 (± 3.6) and dmfs of 6.9 (± 9.9). There was no statistically significant difference between boys and girls. Less caries was observed among children whose parents worked and it was statistically significant as well as whose mothers had high or low educational level. Increased number of family members appeared to have a high incidence of dental caries which was also statistically significant. There was no significant difference in dental caries prevalence with birth order. Conclusions: Dental caries among preschool children in Saudi Arabia was still very common. Improvement of preventive measure at early age should be emphasized by parents and dental health professionals. More attention is required for Non-working parents telling them about the risk of dental caries affecting their children and the awareness of preventive care of dental health. PMID:27182260

    Introduction Dental caries is a common dental disease, which occurs during childhood and continues to be a major public health problem. The prevalence of dental caries was associated with oral hygiene practice, sugar consumption and implementation of the preventive oral health program. Aim The purpose of this study was to assess the prevalence of dental caries in school children aged between 6-14 years using the International Caries Detection and Assessment System (ICDAS II). Materials and Methods The study population consisted of 2796 school children living in Pallikkaranai, Chennai, India and studying in government recognized schools. Each student was examined by a single examiner using ICDAS system under natural light during normal school hours. Results The prevalence of dental caries was 68.8% in the total surveyed population. The gender-wise prevalence of dental caries shows, females to have slightly higher prevalence than male. The prevalence of dental caries at the age group of 6 years was 57%, seven year 67%, eight year 63%, nine year 74%, 10 year 76%, 11 year 74%, 12 year 69%, 13 year 71%, and 14 year 69%. The distribution of CARS (Caries associated with Sealants and Restorations) in the surveyed population was only 1.4% Conclusion The distribution of non-cavitated/early enamel lesions was higher in the studied population and indicated a requirement of a sustained dental health preventive program targeting specific segments of the population.

    Three hundred patients of chronic urticaria were screened for dental affections. Sixty two (20.66%) patients were detected to have dental caries. Among the control group which com-prised of 100 patients, 20% had dental caries. There was thus no increased incidence of dental caries among patients with urticaria. Only 2 patients had remission of urticaria following treat-ment of caries. Dental caries therefore is probably not a cause of chronic urticaria.

    International Nuclear Information System (INIS)

    The purpose of the study was to compare macroscopic and radiographic examination of proximal root surface caries of extracted teeth from patients aged 65-95 years. Although the study conditions for macroscopic and radiographic diagnosis favored more sensitive evaluations than routine clinical conditions, there was a 24% disagreement in diagnosis. This finding indicates that under routine clinical conditions it is difficult to register with certainty all superficial root carious lesions. Even in the absence of clinically detectable root surface caries, preventive measures should be considered for elderly people with exposed root surfaces

    1995-05-01

    Caries selective ablation is fixed to a window of fluences predicted by the ablation thresholds of carious and healthy dentin, respectively. The aim of the study was to develop a dental handpiece which guarantees homogeneous fluence at the irradiated tooth surface. Furthermore the point of treatment should be cooled down without energy losses due to the cooling system. We suggest the direct coupling of the laser radiation into a laminar stream of liquid, which acts in turn as a lengthened beam guide. The impacts of the laser radiation and of the cooling medium fall exactly into the same point. Hot ablation debris is removed out of the crater by the flush of the water jet. Fluences are constant if the handpiece is used in contact mode or at a distance. Normally the surface of a bare fiber working in contact mode is destroyed after a few shots. Coupling the laser radiation into a stream of liquid prevents this destruction. Putting together the benefits of this special handpiece short overall treatment times seem to be possible. High average power can be applied to the tooth without the threat of thermal damage. Furthermore no time consuming cutting of the fiber prolongs the treatment time.

    Caries is caused by acid production in biofilms on dental surfaces. Preventing caries therefore involves control of microorganisms and/or the acid produced. Here, calcium-phosphate-osteopontin particles are presented as a new approach to caries control. The particles are made by co-precipitation and designed to bind to bacteria in biofilms, impede biofilm build-up without killing the microflora, and release phosphate ions to buffer bacterial acid production if the pH decreases below 6. Analysis of biofilm formation and pH in a five-species biofilm model for dental caries showed that treatment with particles or pure osteopontin led to less biofilm formation compared to untreated controls or biofilms treated with osteopontin-free particles. The anti-biofilm effect can thus be ascribed to osteopontin. The particles also led to a slower acidification of the biofilm after exposure to glucose, and the pH always remained above 5.5. Hence, calcium-phosphate-osteopontin particles show potential for applications in caries control. PMID:26923119

    Full Text Available Obesity is a chronic disease characterized by excess body fat, which can lead to other health problems, including insulin resistance, non-alcoholic fatty liver disease, polycystic ovary syndrome, hypertension, dyslipidemia, sleep apnea, asthma, heart attack, stroke, atherosclerosis and metabolic syndrome. Currently, obesity and dental caries are major public health concerns and dietary habits are a very important common component of their etiological factors, showing some correlation with the sociodemographic characteristics of individuals presenting these diseases. In relation to caries experience, the literature suggests a correlation between obesity and dental caries in children and adolescents, in primary and/or permanent dentition, though divergent results exist regarding assessment based on the method recommended by the WHO (1997, i.e., restricted to carious lesions with cavitation. Some studies indicate greater prevalence of proximal carious lesions in obese adolescents compared with those with normal weight. Salivary changes, such as the concentrations of phosphate, sialic acid, proteins and immunoglobulins and in peroxidase activity could explain the increased probability of obese children presenting greater risk of dental caries. Thus, it is important to consider the contribution of salivary parameters in caries experience of overweight children and adolescents and the implementation of preventive measures in this population.

    Full Text Available Background: It is an accepted fact that genetics plays an important role in determination of palmar dermatoglyphic patterns. Since caries is a multifactorial disease with the influence of genetic pattern, this study was undertaken to explore the possibility of dermatoglyphics as a noninvasive and early predictor of dental caries in children, so as to initiate preventive oral health measures at an early age. Materials and Methods: The study group comprised of 200 children aged between 4 and 5 years. The dmfs score was evaluated. The experimental group (Group 1, comprised of 100 children with early childhood caries (ECC with dmfs >5. The control group (Group 2 comprised of 100 children with dmfs score of 0. Results: An increased frequency of ulnar loops in caries-free children and whorls in children with ECC was observed. Low mean atd angle and low mean. Total ridge count was observed in the ECC group. Conclusion: There is definite variation in dermatoglyphics between the ECC and caries-free group, indicating that dermatoglyphic patterns can be used as a predictive tool for children with ECC.

    Although the prevalence of dental caries has decreased gradually in the past three decades in the Australian population, dental caries remains the primary reason for tooth loss in Australia. At the community level, total health expenditure on the treatment of dental caries (and its consequences) is substantial. Accordingly, caries prevention is an important focus at both the individual and community levels. This paper outlines the principles upon which modern caries prevention is based and stresses the importance of manipulating the oral environment (in terms of salivary parameters, ions, pH and the oral flora) as a major strategy for effective long-term caries prevention. Practical advice is provided on the correct home use of preventive agents, including chewing gums, chlorhexidine, fluorides, bicarbonate rinses and phosphopeptides. PMID:10925501

    1999-01-01

    The course of caries depends on an equilibrium between de- and remineralization of enamel. Epidemiologic studies performed during recent years in Poland have demonstrated a high incidence and severity of caries in children and teenagers. Therefore, the actual program of caries prevention covering the whole population of children and teenagers has not performed to the expectations, possibly because the program protocol does not discriminate between children susceptible and resistant to caries. The aims of this work included: 1. Analysis of tooth groups and surfaces as to their susceptibility to caries; 2. Evaluation of the influence of de- and remineralization modifying factors such as: a) dental plaque and sugars, b) caries-causing bacteria, c) enamel resistance to acids, d) biochemical properties of saliva--on the susceptibility to caries; 3. Evaluation of the uptake of fluorides from chewing gum by enamel in relationship to caries susceptibility. An initial clinical examination of permanent teeth was performed in 292 children aged 12 years. Subsequently, two groups were formed: one with 45 children free from caries and another with 77 children at high risk of caries. Control examinations of permanent teeth in both groups were carried out after one and three years from the initial examination. The clinical examination included a check-up of secondary dentition, counting of erupted teeth, sealed teeth, evaluation of oral hygiene status, gingivae, abnormalities in mineralization and measurement of the rate of microdemineralization. The biochemical analysis of saliva was done to measure the content of fluorides, calcium, phosphorus and magnesium, as well as pH. Microsamples of enamel were collected using acid biopsy and the content of calcium and fluorine in the superficial and underlying layer was assayed. The thickness of both layers obtained by biopsy was also measured. Commercial test kits--Dentocult SM and Dentocult LB, served to determine the amount of caries

    Objectives To better understand the effectiveness of xylitol in caries prevention in adults, and to attempt improved clinical trial efficiency. Methods As part of the Xylitol for Adult Caries Trial (X-ACT), non-cavitated and cavitated caries lesions were assessed in subjects who were experiencing the disease. The trial was a test of the effectiveness of 5 grams/day of xylitol, consumed by dissolving in the mouth five 1 gram lozenges spaced across each day, compared with a sucralose placebo. For this analysis, seeking trial efficiency, 538 subjects aged 21–80, with complete data for four dental examinations were selected from the 691 randomized into the three year trial, conducted at three sites. Acceptable inter and intra examiner reliability before and during the trial was quantified using the kappa statistic. Results The mean annualized non-cavitated plus cavitated lesion transition scores in coronal and root surfaces, from sound to carious favoured xylitol over placebo, during the three cumulative periods of 12, 24, and 33 months, but these clinically and statistically non-significant differences declined in magnitude over time. Restricting the present assessment to those subjects with a higher baseline lifetime caries experience showed possible but inconsistent benefit. Conclusions There was no clear and clinically relevant preventive effect of xylitol on caries in adults with adequate fluoride exposure when non-cavitated plus cavitated lesions were assessed. This conformed to the X-ACT trial result assessing cavitated lesions. Including non-cavitated lesion assessment in this full scale, placebo controlled, multi site, randomized, double blinded clinical trial in adults experiencing dental caries, did not achieve added trial efficiency or demonstrate practical benefit of xylitol.

    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. PMID:26662487

    Background Although caries is prevalent in adults, few preventive therapies have been tested in adult populations. This randomized clinical trial evaluated the effectiveness of xylitol lozenges in preventing caries in elevated caries-risk adults. Methods X-ACT was a three-site placebo-controlled randomized trial. Participants (n=691) ages 21–80 consumed five 1.0 g xylitol or placebo lozenges daily for 33 months. Clinical examinations occurred at baseline, 12, 24 and 33 months. Results Xylitol lozenges reduced the caries increment 11%. This reduction, which represented less than one-third of a surface per year, was not statistically significant. There was no indication of a dose-response effect. Conclusions Daily use of xylitol lozenges did not result in a statistically or clinically significant reduction in 33-month caries increment among elevated caries-risk adults. Clinical Implications These results suggest that xylitol used as a supplement in adults does not significantly reduce their caries experience. PMID:23283923

  20. Dental caries - not just holes in teeth! A perspective.

    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.

    This article presents the rationale and content of a current study that seeks to improve methods to identify children at high risk to dental caries. It summarizes the results of the development of a 12-factor, preliminary caries prediction model based on data derived from the National Preventive Demonstration Program. Despite data limitations, the model produced a sensitivity of .5 and specificity of .8 for four-year caries increment prediction in first- and fifth-grade children. Data on a number of additional potential predictors are being collected in two sites to expand and improve the existing model. These factors are identified. PMID:3184028

    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. PMID:26192983

    Full Text Available Abstract Background Fall prevention interventions for community-dwelling older adults have been found to reduce falls in some research studies. However, wider implementation of fall prevention activities in routine care has yielded mixed results. We implemented a theory-driven program to improve care for falls at our Veterans Affairs healthcare facility. The first project arising from this program used a nurse advice telephone line to identify patients' risk factors for falls and to triage patients to appropriate services. Here we report the formative evaluation of this project. Methods To evaluate the intervention we: 1 interviewed patient and employee stakeholders, 2 reviewed participating patients' electronic health record data and 3 abstracted information from meeting minutes. We describe the implementation process, including whether the project was implemented according to plan; identify barriers and facilitators to implementation; and assess the incremental benefit to the quality of health care for fall prevention received by patients in the project. We also estimate the cost of developing the pilot project. Results The project underwent multiple changes over its life span, including the addition of an option to mail patients educational materials about falls. During the project's lifespan, 113 patients were considered for inclusion and 35 participated. Patient and employee interviews suggested support for the project, but revealed that transportation to medical care was a major barrier in following up on fall risks identified by nurse telephone triage. Medical record review showed that the project enhanced usual medical care with respect to home safety counseling. We discontinued the program after 18 months due to staffing limitations and competing priorities. We estimated a cost of $9194 for meeting time to develop the project. Conclusions The project appeared feasible at its outset but could not be sustained past the first cycle of

    It is well established that the development of new technologies for early detection and quantitative monitoring of dental caries at its early stage could provide health and economic benefits ranging from timely preventive interventions to reduction of the time required for clinical trials of anti-caries agents. However, the new technologies currently used in clinical setting cannot assess and monitor caries using the actual mineral concentration within the lesion, while a laboratory-based microcomputed tomography (MCT) has been shown to possess this capability. Thus we envision the establishment of mathematical equations relating the measurements of each of the clinical technologies to that of MCT will enable the mineral concentration of lesions detected and assessed in clinical practice to be extrapolated from the equation, and this will facilitate preventitive care in dentistry to lower treatment cost. We utilize MCT and the two prominent clinical caries assessment devices (Quantitative Light-induced Fluorescence [QLF] and Diagnodent) to longitudinally monitor the development of caries in a continuous flow mixed-organisms biofilm model (artificial mouth), and then used the collected data to establish mathematical equation relating the measurements of each of the clinical technologies to that of MCT. A linear correlation was observed between the measurements of MicroCT and that of QLF and Diagnodent. Thus mineral density in a carious lesion detected and measured using QLF or Diagnodent can be extrapolated using the developed equation. This highlights the usefulness of MCT for monitoring the progress of an early caries being treated with therapeutic agents in clinical practice or trials.

    The aim of the study was to investigate the efficacy of the use of xylitol-containing tooth-wipes in preventing dental caries in young children. In a double-blinded randomized controlled clinical trial, 44 mothers with active caries and their 6- to 35-month-old children were randomized to xylitol-wipe or placebo-wipe groups. The children’s caries scores were recorded at baseline and 1 year. Salivary levels of mutans streptococci and lactobacilli were enumerated at baseline, 3, 6, and 12 months. Data were analyzed by intent-to-treat modeling with imputation for caries lesions and a linear mixed-effect model for bacterial levels. Significantly fewer children in the xylitol-wipe group had new caries lesions at 1 year compared with those in the placebo-wipe group (P < 0.05). No significant differences between the two groups were observed in levels of mutans streptococci and lactobacilli at all time-points. Daily xylitol-wipe application significantly reduced the caries incidence in young children as compared with wipes without xylitol, suggesting that the use of xylitol wipes may be a useful adjunct for caries control in infants (Clinicaltrials.gov registration number CT01468727).

    Full Text Available Background: Dental caries is one of the most preventable yet prevalent chronic diseases worldwide. Our objective was to evaluate the effect of family structure and behavioral and eyesight problems as they relate to caries severity in schoolchildren.Methods: This research was carried out on 845 primary schoolchildren aged 9 yr in Kerman, Iran, in 2012. Ten variables, including health records, family structure information and a dmft/DMFT index, were collected. Children were categorized into three groups based on the WHO caries severity classification. Low caries level was defined as dmft/DMFT4.4. The Cochran–Armitage test and ordinal logistic regression were employed for data analysis.Results: Almost half of pupils had moderate or high caries severity. The odds of being in a higher caries severity category in pupils with behavioral problems (OR=2.37, 95% CI: 1.29-4.38 and girls (OR=1.6, 95% CI: 1.22-2.06 were higher than in other categories. In addition, pupils with eyesight problems (OR=0.58, 95% CI: 0.37-0.90 and overweight pupils (OR=0.46, 95% CI: 0.31-0.71 had lower caries severity than others. The effects of parents’ education, birth rank, living with parents and consanguineous relationship between parents were not significant on caries severity (P>0.05.Conclusions: Female pupils with behavioral problems were at a higher risk of caries severity than other pupils. These pupils need to be educated and coached on proper dental care. In addition, overweight pupils and those with eyesight problems had less caries severity than others. Family structure in this study did not have an effect on the severity of dental caries.

    We evaluated the predictive and construct validity of a caries activity assessment system associated with the International Caries Detection and Assessment System (ICDAS) in primary teeth. A total of 469 children were reexamined: participants of a caries survey performed 2 yr before (follow-up rate of 73.4%). At baseline, children (12-59 mo old) were examined with the ICDAS and a caries activity assessment system. The predictive validity was assessed by evaluating the risk of active caries lesion progression to more severe conditions in the follow-up, compared with inactive lesions. We also assessed if children with a higher number of active caries lesions were more likely to develop new lesions (construct validity). Noncavitated active caries lesions at occlusal surfaces presented higher risk of progression than inactive ones. Children with a higher number of active lesions and with higher caries experience presented higher risk of developing new lesions. In conclusion, the caries activity system associated with the ICDAS presents predictive and construct validity in primary teeth in the assessment of occlusal caries lesions, but predictive validity was not observed in smooth surfaces.

    Governments and donors are investing considerable resources on HIV prevention in order to scale up these services rapidly. Given the current economic climate, providers of HIV prevention services increasingly need to demonstrate that these investments offer good 'value for money'. One of the primary routes to achieve efficiency is to take advantage of economies of scale (a reduction in the average cost of a health service as provision scales-up), yet empirical evidence on economies of scale is scarce. Methodologically, the estimation of economies of scale is hampered by several statistical issues preventing causal inference and thus making the estimation of economies of scale complex. In order to estimate unbiased economies of scale when scaling up HIV prevention services, we apply our analysis to one of the few HIV prevention programmes globally delivered at a large scale: the Indian Avahan initiative. We costed the project by collecting data from the 138 Avahan NGOs and the supporting partners in the first four years of its scale-up, between 2004 and 2007. We develop a parsimonious empirical model and apply a system Generalized Method of Moments (GMM) and fixed-effects Instrumental Variable (IV) estimators to estimate unbiased economies of scale. At the programme level, we find that, after controlling for the endogeneity of scale, the scale-up of Avahan has generated high economies of scale. Our findings suggest that average cost reductions per person reached are achievable when scaling-up HIV prevention in low and middle income countries. PMID:25779621

    Tobacco use experimentation is most frequent between the ages of 15–24 in India. Therefore, programming to counteract tobacco use among adolescents is needed. There is a lack of evidence-based teen tobacco use prevention and cessation programs. The current study provides an outcome evaluation of the Project EX tobacco use prevention and cessation program among Indian adolescents (16–18 years). An eight-session classroom-based curriculum was adapted to the Indian context and translated from English to Hindi (local language). Next, it was tested using a quasi-experimental design with 624 Indian students at baseline, involving two program and two control schools, with a three-month post-program follow-up. Project EX involves motivation enhancement (e.g., talk shows and games) and coping skills (e.g., complementary and alternative medicine) components. Program participants rated complementary and alternative medicine (CAM) activities like meditation, yoga and healthy breathing higher than talk shows and games. Compared to the standard care control condition, the program condition revealed a prevention effect, but not a cessation effect. Implications for prevention/cessation programming among Indian teens are discussed. This study was approved by the Independent Ethics Committee, Mumbai. PMID:26454232

    Full Text Available Objectives. Dental caries is the most common chronic childhood disease, with numerous identified risk factors. Risk factor differences could indicate the need to target caregiver/patient education/preventive care intervention strategies based on population and/or individual characteristics. The purpose of this study was to evaluate caries risk factors differences by race/ethnicity, income, and education. Methods. We enrolled 396 caregiver-toddler pairs and administered a 105-item questionnaire addressing demographics, access to care, oral bacteria transmission, caregiver's/toddler's dental and medical health practices, caregiver's dental beliefs, and caregiver's/toddler's snacking/drinking habits. Logistic regressions and ANOVAs were used to evaluate the associations of questionnaire responses with caregiver's race/ethnicity, income, and education. Results. Caregivers self-identified as Non-Hispanic African-American (44%, Non-Hispanic White (36%, Hispanic (19%, and “other” (1%. Differences related to race/ethnicity, income, and education were found in all risk factor categories. Conclusions. Planning of caregiver/patient education/preventive care intervention strategies should be undertaken with these caries risk factor differences kept in mind.

    The main factors predisposing the onset of the carious process are: 1 the presence of bacterial species able to lower the pH until critical values of 5.5, 2 the absence of adequate oral hygiene, 3 an inefficient immune response anti-caries, 4 the type of alimentary diet and 5 the structure of the teeth. Among the 200 bacterial species isolated from dental plaque the most pathogenic for dental caries are: Streptococcus mutans, Streptococcus sobrinus, Lactobacillus acidophilus, Actinomices viscusus and Bifidobacterium dentium. Our laboratory (LAB® s.r.l., Codigoro, Ferrara, Italy has developed a test for absolute and relative quantification of the most common oral cariogenic bacteria. The test uses specific primers and probes for the amplification of bacteria genome sequences in Polymerase Chain Reaction Real Time. The results provide a profile of patient infection, helpful for improving the diagnosis and planning of preventive treatment to reduce the bacterial load.

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. PMID:23905153

    Dental caries on tooth surfaces is still a problem in many industrialized countries. For many years, dentistry was influenced by a mechanical approach characterized by the use of high-speed rotary cutting instruments, and dentists predominantly used surgical methods to address caries. This included radical removal of diseased portions of the tooth, along with material-driven geometric extensions to areas that were assumed to be caries-resistant. This concept of extension for prevention was introduced by G. V. Black and influenced dentists for more than 120 years. Recently, a new paradigm of operative conservatism, sometimes referred to as "minimally invasive dentistry," has gained popularity. This paradigm is designed to promote maximum preservation of healthy dental structures over a lifetime. The aim of this review is to discuss the efficacy of current nonsurgical treatments for non-cavitated caries lesions in permanent teeth. Based on results obtained from clinical trials, this review evaluates treatments such as consumption of CPP-ACP added gums, resin infiltration and fissure sealing. Although in a few cases an invasive approach is needed to arrest caries progression, the non-surgical approach generally provides potential benefits that include conserving structure by delaying intervention or minimizing the operative procedure. All current non-invasive methods are effective in treating non-cavitated caries lesions. The adoption of non-invasive approaches in the management of these lesions can preserve dental tissues, thus increasing tooth longevity. PMID:21494394

    Full Text Available Realization that dental caries is a reversible, dynamic biochemical event at a micron level has changed the way the profession recognizes the caries disease and the caries lesion. The diagnosis of dental caries poses challenges due to the complex interaction of multiple endogenous causal factors. The most appropriate diagnostic aid for this purpose is the risk model of caries risk assessment. The analyses of the biological determinants provide clues to the dominant causal factor. The detection of a carious lesion has undergone a rigorous revision and revolution in order to identify the earliest mineral change so that it can be controlled without resorting to invasive management options. Apart from detection, it became mandatory to assess the extent of the lesion (noncavitated/cavitated, assess the activity status of the lesion (active/arrested, monitor the lesion progress (progression/regression over a period of time, and finally to predict the prognosis of the lesion as well as the disease. The prognosis of the disease can be best assessed by analyzing the predictor factors in caries risk assessment. The ultimate objective of such a meticulous and methodical approach aids in devising a tailor-made treatment plan, using preventing measures precisely and restorative measures minimally. This ensures the best oral health outcome of the patient.

    Full Text Available Dental caries is a transmissible infectious disease in which mutans streptococci are generally considered to be the main etiological agents. Although the transmissibility of dental caries is relatively well established in the literature, little is known whether information regarding this issue is correctly provided to the population. The present study aimed at evaluating, by means of a questionnaire, the knowledge and usual attitude of 640 parents and caretakers regarding the transmissibility of caries disease. Most interviewed adults did not know the concept of dental caries being an infectious and transmissible disease, and reported the habit of blowing and tasting food, sharing utensils and kissing the children on their mouth. 372 (58.1% adults reported that their children had already been seen by a dentist, 264 (41.3% answered that their children had never gone to a dentist, and 4 (0.6% did not know. When the adults were asked whether their children had already had dental caries, 107 (16.7% answered yes, 489 (76.4% answered no, and 44 (6.9% did not know. Taken together, these data reinforce the need to provide the population with some important information regarding the transmission of dental caries in order to facilitate a more comprehensive approach towards the prevention of the disease.

  1. Teeth Caries Decay in MR Imaging

    International Nuclear Information System (INIS)

    X-ray based visualization techniques were for many years the only way to asses structure and state of the human teeth. MRI has been used in the research of the healthy and decayed teeth during last decade. Several papers were presented showing usefulness of spin echo and gradient echo imaging, Single Point Imaging, SPRITE and STRAFI techniques for visualization of the dental surface geometry as well as for distinction between soft tissue (pulp) and mineralized tissue (enamel, dentine and root cement) in the extracted teeth. Recently, MRI was used for estimation of the facial bone structure, in preparation to implantation, localization of the tumor in the facial bone tissue, and in detection of the osteoporosis. The aim of this work was to investigate potential of MRI for detection and estimation of the caries, on the level of laboratory pre-clinical tests. This work was done within the project to develop original, MRI based diagnostic technique for dentistry needs. MRI experiments were performed on the 5 decayed extracted human teeth (impossible conservative therapy), obtained at Dept. of Dental Surgery MUS. After extraction teeth were stored in saline. MRI measurements were done in MR Tomography Lab INP. Prior to the experiment, tooth was degassed to minimize magnetic susceptibility artifacts. A 3D spin echo pulse sequence on the 4.7 T research MRI system, equipped with Maran DRX console, and dedicated home-built probe head, was used to obtain three dimensional (256x128x128) images of the teeth. Corresponding resolution was 60x120x160 mm3. High intensity signal from water penetrated into the porous decayed regions of tooth, contrasted with lack of signal from mineralized tooth tissue, allow for visualization of the presence and extent of caries. Among the 5 measured teeth, MRI allows for detection of the caries in two most decayed tooth. High intensity signal from water penetrated into the porous decayed regions of tooth, contrasted with lack of signal from

    Full Text Available Background: Severe tooth decay is known to affect the health and well-being of young children. However, there has been minimal research showing the association of severe early childhood caries (S-ECC and iron deficiency anemia (IDA. Aims: The primary aim of this study was to investigate an association between S-ECC with IDA. The secondary objective was to find an association between severe caries and body weight of the child. The oral health-related quality of life of children with S-ECC was also assessed. Materials and Methods: Following the ethical approval, 60 children aged 2-6 years (30 with S-ECC and 30 controls with caries status <2 were recruited for this cross-sectional association study. Each child received a clinical examination for dental caries status using deft index and a blood investigation to determine various parameters; hemoglobin (Hb, mean corpuscular volume (MCV, mean corpuscular hemoglobin concentration, and packed cell volume (PCV. Children underwent venipuncture after due parental consent, and 2.5 mL blood was collected from each child to evaluate the above parameters. Following this, the parents filled up a 10 point questionnaire to determine the child′s quality of life. Data were then analyzed by t-test and Fischer′s exact t-test. Result: On comparison of percentage of children with IDA in S-ECC and control group, it was found that children with S-ECC were more likely to have IDA odds ratio (95% confidence interval: 10.77 (2.0, 104.9, (P = 0.001. In addition to this, S-ECC children were significantly more likely to have low Hb, MCV, and PCV levels (P < 0.001 which imply that S-ECC may be a risk marker for the development of anemia. More children (93% with severe caries were found to have less body weight than ICMR standard weight for age as compared to children with low caries (P < 0.05%. Conclusion: S-ECC is strongly associated with the anemia due to iron deficiency, and efforts should be made toward the preventive

    The emergence of clinical care pathways within dentistry has placed renewed emphasis on the caries risk assessment of patients to help predict further disease and guide future prevention and intervention strategies. With dietary intake of non-milk extrinsic sugars (NMES) a key aetiological factor in the development of caries, the predictive level of risk posed by some dietary habits is questioned. Therefore the aim of this study was to investigate the influence of dietary habits on the preval...

    2016-01-01

    This paper reviews the first part of the outcomes of the ORCA Saturday Afternoon Symposium 2014 dealing with 'caries epidemiology and community dentistry: chances for future improvements in caries risk groups'. After the caries decline in many countries, there are remaining pockets of higher caries levels, mostly in the primary dentition and/or linked to a low socio-economic status (SES). The review into the evidence of caries-preventive measures clearly points to the use of fluorides, especially toothbrushing with fluoridated toothpaste and collective measures such as water fluoridation. In contrast to several unsuccessful high-risk approaches, community and public health programmes seem to be able to ensure a population-wide access and compliance in risk groups. Their simple and evidence-based measures mostly combine regular plaque removal and fluoride applications via toothbrushing, at least for children and adolescents. For the future, the common risk factor approach which addresses associations between oral health, social deprivation, diet, hygiene, smoking, alcohol use and stress should lead to combined efforts with other community health and education specialists. Further engagement with public policy, community leaders and administration is needed in order to strengthen healthy choices and behaviour, e.g. in 'healthy' schools and kindergartens. It seems advisable that these population programmes also aim at improving upstream factors. PMID:26752628

    The Adolescents Surveillance System for Obesity prevention (ASSO) Project aimed at developing standardized and web-based tools for collecting data on adolescents' obesity and its potential determinants. This has been implemented and piloted in the local area of Palermo city, Italy. The aim of the present study is to provide an overview of the Project's design, implementation, and evaluation, highlighting all the aspects for a potential scale-up of the surveillance system on the whole national territory and abroad, as a sustainable and effective source of data.The overall structure and management, the ASSO-toolkit, the ASSO-NutFit software, and all developed and used procedures for recruiting, training, and data collecting/analyzing are addressed. An interim evaluation has been performed through a feasibility study; a final Project evaluation has been performed reporting the Strengths, Weaknesses, Opportunities, and Threats (SWOT) and the attributes that a surveillance system should have.This article provides a detailed overview of the Project and highlights that ASSO can be considered a valid, logical, coherent, efficient, and sustainable surveillance system that is consistent with countries' needs and priorities.The system developed by the ASSO Project provides high-quality data and complies with several characteristics typical of a suitable surveillance system. It has a potential of being adopted within the National Health Service and other countries' Health Services for monitoring adolescents' obesity and its determinants, such as food intakes, behaviors, physical activity, and fitness profiles.

    Past research suggests that as many as 50% of onward human immunodeficiency virus (HIV) transmissions occur during acute and recent HIV infection. It is clearly important to develop interventions which focus on this highly infectious stage of HIV infection to prevent further transmission in the risk networks of acutely and recently infected individuals. Project Protect tries to find recently and acutely infected individuals and prevents HIV transmission in their risk networks. Participants are recruited by community health outreach workers at community-based HIV testing sites and drug users’ community venues, by coupon referrals and through referrals from AIDS clinics. When a network with acute/recent infection is identified, network members are interviewed about their risky behaviors, network information is collected, and blood is drawn for HIV testing. Participants are also educated and given prevention materials (condoms, syringes, educational materials); HIV-infected participants are referred to AIDS clinics and are assisted with access to care. Community alerts about elevated risk of HIV transmission are distributed within the risk networks of recently infected. Overall, 342 people were recruited to the project and screened for acute/recent HIV infection. Only six index cases of recent infection (2.3% of all people screened) were found through primary screening at voluntary counseling and testing (VCT) sites, but six cases of recent infection were found through contact tracing of these recently infected participants (7% of network members who came to the interview). Combining screening at VCT sites and contact tracing the number of recently infected people we located as compared to VCT screening alone. No adverse events were encountered. These first results provide evidence for the theory behind the intervention, i.e., in the risk networks of recently infected people there are other people with recent HIV infection and they can be successfully located

    Dental caries is a disease in which minerals of the tooth are dissolved by surrounding bacterial plaques. A caries process present for some time may result in a caries lesion. However, if it is detected early enough, the dentist and dental professionals can implement measures to reverse and control caries. Several optical, nonionized methods have been investigated and used to detect dental caries in early stages. However, there is not a method that can singly detect the caries process with both high sensitivity and high specificity. In this paper, we present a multimodal imaging system that combines visible reflectance, fluorescence, and Optical Coherence Tomography (OCT) imaging. This imaging system is designed to obtain one or more two-dimensional images of the tooth (reflectance and fluorescence images) and a three-dimensional OCT image providing depth and size information of the caries. The combination of two- and three-dimensional images of the tooth has the potential for highly sensitive and specific detection of dental caries.

    Tooth decay is considered the most prevalent human disease worldwide. We present the first metaproteomic study of the oral biofilm, using different mass spectrometry approaches that have allowed us to quantify individual peptides in healthy and caries-bearing individuals. A total of 7771 bacterial and 853 human proteins were identified in 17 individuals, which provide the first available protein repertoire of human dental plaque. Actinomyces and Coryneybacterium represent a large proportion of the protein activity followed by Rothia and Streptococcus. Those four genera account for 60-90% of total diversity. Healthy individuals appeared to have significantly higher amounts of L-lactate dehydrogenase and the arginine deiminase system, both implicated in pH buffering. Other proteins found to be at significantly higher levels in healthy individuals were involved in exopolysaccharide synthesis, iron metabolism and immune response. We applied multivariate analysis in order to find the minimum set of proteins that better allows discrimination of healthy and caries-affected dental plaque samples, detecting seven bacterial and five human protein functions that allow determining the health status of the studied individuals with an estimated specificity and sensitivity over 96%. We propose that future validation of these potential biomarkers in larger sample size studies may serve to develop diagnostic tests of caries risk that could be used in tooth decay prevention.

    Full Text Available Abstract Background Bacterial adhesion is an important determinant of colonization and infection, including dental caries. The salivary scavenger receptor cysteine-rich glycoprotein gp-340, which mediates adhesion of Streptococcus mutans (implicated in caries, harbours three major size variants, designated gp-340 I to III, each specific to an individual saliva. Here we have examined the association of the gp-340 I to III polymorphisms with caries experience and adhesion of S. mutans. Methods A case-referent study was performed in 12-year-old Swedish children with high (n = 19 or low (n = 19 caries experiences. We measured the gp-340 I to III saliva phenotypes and correlated those with multiple outcome measures for caries experience and saliva adhesion of S. mutans using the partial least squares (PLS multivariate projection technique. In addition, we used traditional statistics and 2-year caries increment to verify the established PLS associations, and bacterial adhesion to purified gp-340 I to III proteins to support possible mechanisms. Results All except one subject were typed as gp-340 I to III (10, 23 and 4, respectively. The gp-340 I phenotype correlated positively with caries experience (VIP = 1.37 and saliva adhesion of S. mutans Ingbritt (VIP = 1.47. The gp-340 II and III phenotypes tended to behave in the opposite way. Moreover, the gp-340 I phenotype tended to show an increased 2-year caries increment compared to phenotypes II/III. Purified gp-340 I protein mediated markedly higher adhesion of S. mutans strains Ingbritt and NG8 and Lactococcus lactis expressing AgI/II adhesins (SpaP or PAc compared to gp-340 II and III proteins. In addition, the gp-340 I protein appeared over represented in subjects positive for Db, an allelic acidic PRP variant associated with caries, and subjects positive for both gp-340 I and Db tended to experience more caries than those negative for both proteins. Conclusion Gp-340 I behaves as a caries

    The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Digital radiographs of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size no.2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52 mm2. The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

    The Forsyth County Cervical Cancer Prevention Project (FCP) is a community-based health education project funded by the National Cancer Institute. The target population includes around 25 000 black women age 18 and older who reside in Forsyth County, North Carolina. The overall goal of the program is to prevent mortality from cervical cancer by promoting Pap smears and return for follow-up care when needed. Based on the principles of social marketing, a plan to reach the target population with mass media educational messages through electronic and print channels was developed. Guided by marketing objectives, the target population was divided into relatively discrete segments. The segments included church attenders, patients in waiting rooms of public and selected health providers, female students at local colleges, shoppers, viewers of radio and television, newspaper readers, and business owners and managers. Introduction of the program was based on strategies developed for reaching the target population in each segment with television, radio and print mass media messages. Qualitative assessment of the mass media developed by the program indicated that all forms of communication helped to increase awareness of the program. PMID:10148691

    Full Text Available Cariogram is a computer program that uses an algorithm to assess caries risk. Although the use of Cariogram has recently increased, little information is available regarding its effectiveness in adults. This study aimed to determine whether caries risk from Cariogram relates to caries experience in adults. One hundred and eighty Cariogram files were completed from patients aged ten to fifty-six years (mean: 23.28 years. Seven factors from the software were included from patient records to complete the Cariogram: caries experience, diet (content and frequency, stimulated salivary flow, hygiene index, related diseases and fluoride usage. The percentages of "chances of avoiding new lesions" (caries risk were obtained from Cariogram, and the subjects were classified into five risk groups. Results were compared for each variable with ANOVA, and a correlation between caries and Cariogram variables was calculated by Pearson's correlation coefficient. A multivariate regression model was also used. Only three patients were classified as low risk, and none were classified as very low risk. Thus, only the four upper quintiles were considered for the analysis, and the lower quintile was not considered in the study. Neither DMFT nor the number of lesions were significantly different among the Cariogram's risk categories (p > 0.05. Only diet content was significantly correlated with caries experience (p = 0.006. Caries lesions failed to correlate with any Cariogram variable (p > 0.05. Age, not sex or caries risk scores, showed a strong and positive association with DMFT (p < 0.01. Caries risk from Cariogram appears to be unrelated with caries experience or caries lesions in a high-caries adult population.

    PREFER is a Copernicus Emergency project funded from the 2012 FP7 Space Work Programme, and it is aimed at developing products and services that will contribute to improve the European capacity to respond to the preparedness, prevention, and recovery management steps in the case of forest fire emergency cycle, with focus on the Mediterranean area. It is well known from the most recent reports on state of Europe's forests that the Mediterranean area is particularly affected by uncontrolled forest fires, with a number of negative consequences on ecosystems, such as desertification and soil erosion, and on the local economy. Most likely, the current risks of forest fires will be exacerbated by climate change. In particular, the climate of Southern Europe and the Mediterranean basin is projected to warm at a rate exceeding the global average. Wild fires will therefore remain the most serious threat to Southern European forests. In this situation, the need to collect better information and more knowledge concerning future risks of forest fires and fire prevention in the Mediterranean area is widely recognized to be a major urgent one. As part of the Copernicus programme (i.e. the European Earth Observation Programme), PREFER is based on advanced geo-information products using in particular the earth observation data acquired and developed in the frame of Copernicus. The objective of the PREFER project, started at the end of 2012, 8 partners (from Italy, Portugal, Spain, France and Greece) involved and three years schedule, is the design, development and demonstration of a pre-operational "end-to-end" information service, fully exploiting satellite sensors data and able to support prevention/ preparedness and recovery phases of the Forest Fires emergency cycle in the EU Mediterranean Region. The PREFER information is as general as to be usable in the different countries of the Mediterranean Region, and acts in full complement to already existing services, such as the EC

    Dental caries is a common multifactorial disease, resulting from the interaction of biofilm, cariogenic diet and host response over time. Lactotransferrin (LTF) is a main salivary glycoprotein, which modulates the host immune-inflammatory and antibacterial response. Although a genetic component for caries outcome has been identified, little is known over the genetic aspects underlying its susceptibility. Thus, the aim of this study was to investigate the association between LTF polymorphisms and caries susceptibility. Six hundred seventy seven 12-year-old students were selected: 346 with (DMFT ≥ 1) and 331 without caries experience (DMFT = 0). Also, individuals concentrating higher levels of disease (polarization group, DMFT ≥ 2, n = 253) were tested against those with DMFT ≤ 1 (n = 424). Along with clinical parameters, three representative LTF tag SNPs (rs6441989, rs2073495, rs11716497) were genotyped and the results were evaluated using univariate and multivariate analyses. Allele A for tag SNP rs6441989 was found to be significantly less frequent in the polarization group, conferring a protective effect against caries experience [AA + AG × GG (OR: 0.710, 95% CI: 0.514-0.980, p = 0.045)], and remained significantly associated with caries protection in the presence of gingivitis (p = 0.020) and plaque (p = 0.035). These results might contribute to the understanding of the genetic control of caries susceptibility in humans. PMID:25998152

    Full Text Available The aim of this study was to analyze the influence of socio-behavioral variables on the prevalence and severity of dental caries in 4- to 6-year-old children. 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.

    Dental caries is caused by a combination of infection and diet. This disease, if left untreated, may lead to pain, and impair the quality of life, nutritional status and development of young children. The objective was to investigate the association between snacking and caries in a population at high risk of dental caries. American preschool children (n = 1,206) were recruited in the offices of paediatricians. Data on sociodemographic characteristics, oral hygiene, breast-feeding, use of bottle and snacking were collected by questionnaire. Plaque presence, the number of teeth and their caries status (deft) were scored. The children sampled were 61% Black, 27% White and 10% Asian. Of the 1- to 2-, 2- to 3- and 3- to 4-year-old children, 93.8, 82.4 and 77.3% were caries free, and their mean caries scores were 0.16, 0.58 and 0.93, respectively. Multivariate partial least squares (PLS) modelling revealed plaque presence, lowest income, descriptors for tooth exposure time (number of teeth and age) and cariogenic challenge (total intake of sugar-containing snacks and chips/crisps, and chips intake with a sugar-containing drink) to be associated with more caries. These differences were also found in univariate analyses; in addition, children who continued breast-feeding after falling asleep had significantly higher deft values than those who did not. PLS modelling revealed that eating chips clustered with eating many sweet snacks, candies, popcorn and ice cream. We conclude that, in addition to the traditional risk indicators for caries - presence of plaque, sugar intake and socioeconomic status -, consumption of chips was associated with caries in young children.

    Dental caries is the leading cause of tooth loss, which can promptly be prevented if detected in early stages of progression. Unfortunately, conventional diagnostic modalities currently used in dentistry lack the sensitivity to detect early caries. The authors' intention is to compare the ability of polarized Raman spectroscopy and thermophotonic imaging to make early caries diagnosis. Extracted human teeth with no visible stain or defects were artificially demineralized in accordance to a well-known protocol in dentistry for simulated early caries development at several demineralization stages. Samples were then inspected using polarized Raman spectroscopy and thermophotonic imaging. The sensitivities of these two diagnostic modalities are compared, and the results are verified using transverse micro-radiography. It was found that compared to polarized Raman spectroscopy, thermophotonic imaging exhibits superior sensitivity to very early stages of demineralization.

    2015-03-01

    Full Text Available A dental biofilm forms a distinct environment where microorganisms live in a matrix of extracellular polysaccharides. The biofilm favors certain bacteria and creates a habitat that functions differently compared to planktonic bacteria. Reproducible model systems which help to address various questions related to biofilm formation, the process of caries development, and its prevention are needed and are continuously developed. Recent research using both batch culture, continuous culture and flow cells in caries biofilm formation is presented. The development of new techniques and equipment has led to a deeper understanding of how caries biofilms function. Biofilm models have also been used in the development of materials inhibiting secondary caries. This short review summarizes available models to study these questions.

    In Germany, caries of young people has been declining since the late 1980s, while the prevalence of early childhood caries has remained steady. Data from a number of regional studies suggest a current prevalence between 10% and 15%. However, there is a dearth of longitudinal observational study data on the risk of caries in the permanent teeth of persons who as children had to undergo comprehensive treatment for caries under intubation general anesthesia. The aim of this study was to compare caries experience in the permanent teeth of patients who had to undergo surgical treatment under general anesthesia as a result of non-compliance with caries treatment in early childhood with the experience of patients who did not develop caries at a young age. Analysis of the data revealed that severe caries experience during early childhood resulted in a more severe caries experience during adulthood (difference: 14.8 DMFS; p = 0.001). This increase in caries experience applied to both untreated and treated carious surfaces, and was also apparent in relation to tooth extractions. When compared with persons whose first teeth had been caries-free, patients with severe childhood caries experience tended to show poorer dental hygiene in relation to smooth (p < 0.06) and interproximal (p < 0.04) surfaces. Patients who had been non-compliant as young children were not found to suffer from dental anxiety as young adults. Patients in the treatment and control groups differed with regard to dental health. Aside from being statistically relevant, these differences also have implications for clinical dental practice. PMID:26915485

  2. Diet and Dental Caries: The Pivotal Role of Free Sugars Reemphasized.

    Science.gov (United States)

    Sheiham, A; James, W P T

    2015-10-01

    The importance of sugars as a cause of caries is underemphasized and not prominent in preventive strategies. This is despite overwhelming evidence of its unique role in causing a worldwide caries epidemic. Why this neglect? One reason is that researchers mistakenly consider caries to be a multifactorial disease; they also concentrate mainly on mitigating factors, particularly fluoride. However, this is to misunderstand that the only cause of caries is dietary sugars. These provide a substrate for cariogenic oral bacteria to flourish and to generate enamel-demineralizing acids. Modifying factors such as fluoride and dental hygiene would not be needed if we tackled the single cause--sugars. In this article, we demonstrate the sensitivity of cariogenesis to even very low sugars intakes. Quantitative analyses show a log-linear dose-response relationship between the sucrose or its monosaccharide intakes and the progressive lifelong development of caries. This results in a substantial dental health burden throughout life. Processed starches have cariogenic potential when accompanying sucrose, but human studies do not provide unequivocal data of their cariogenicity. The long-standing failure to identify the need for drastic national reductions in sugars intakes reflects scientific confusion partly induced by pressure from major industrial sugar interests.

    Full Text Available Aim. To examine whether mothers' early employment status is related to the development of severe early childhood caries in their child. Methods. Questionnaire survey of 429 first-time mothers in metropolitan Adelaide, South Australia, and dental examinations of their child at 20 months of age. Results. At months of age, 5.6% of children exhibited caries defined as one or more demineralized or cavitated lesions on the upper incisors. Of the mothers, 52.2% had no paid employment, 39.6% were part-time and 8.2% full-time employed. Overall, mothers' participation in the workforce had no influence on the frequency of severe early childhood caries in their child, but there was a significant interaction with family structure. For mothers without employment there was no difference between single, and two-parent families, but children with an employed single mother more frequently had caries than those with a working mother in a two-parent family (. However, there were no significant differences in children's reported general health. Conclusions. The data indicate a need to explore strategies that may assist single mothers and especially those in the workforce to prevent severe early childhood caries in their child.

Genscreen ultra HIV Ag-Ab “special-tests” are used to detect cases of acute infection. Recent infection is defined as positive test result and preceding negative result within 6 months and/or age younger than 21 years old.RESULTS. In the two cities 173 respondents were recruited to the project, 118 special tests were done. No cases of acute infection and eleven cases of recent infection were found (8 injection drug users (IDUs with preceding negative result within 6 months, 2 IDUs younger than 21 recruited by project team; one non-IDU with preceding negative result within 6 months referred from AIDS-Center. Six recent cases were recruited through screening at VCT sites, 5 others through contact tracing. Psychologists conducted 41 interviews with recent infection cases and their risk networks` members; 176 community alert flyers were distributed to members of risk networks during the interview by psychologist, at the venue by social worker and by participants themselves; 3 drug use venues were visited by project team with concomitant HIV-testing of people present at the venue. CONCLUSIONS. Network tracing seems to be feasible and to help find recently infected people. Further research is needed to tell whether this

  5. PREVENTING POLLUTION USING ISO 14001 AT A PARTICLE ACCELERATOR THE RELATIVISTIC HEAVY ION COLLIDER PROJECT

    International Nuclear Information System (INIS)

    In early 1997 Brookhaven National Laboratory (BNL) discovered that the spent fuel pool of their High Flux Beam Reactor was leaking tritium into the groundwater. Community members, activist groups, politicians and regulators were outraged with the poor environmental management practices at BNL. The reactor was shut down and the Department of Energy (DOE) terminated the contract with the existing Management Company. At this same time, a major new scientific facility, the Relativistic Heavy Ion Collider (RHIC), was nearing the end of construction and readying for commissioning. Although environmental considerations had been incorporated into the design of the facility; some interested parties were skeptical that this new facility would not cause significant environmental impacts. RHIC management recognized that the future of its operation was dependent on preventing pollution and allaying concerns of its stakeholders. Although never done at a DOE National Laboratory before Brookhaven Science Associates, the new management firm, committed to implementing an Environmental Management System (EMS) and RHIC managers volunteered to deploy it within their facility on an extremely aggressive schedule. Several of these IS0 requirements contribute directly to preventing pollution, an area where particular emphasis was placed. This paper describes how Brookhaven used the following key IS0 14001 elements to institutionalize Pollution Prevention concepts: Environmental Policy, Aspects, Objectives and Targets, Environmental Management Program, Structure and Responsibility, Operational Controls, Training, and Management Review. In addition, examples of implementation at the RHIC Project illustrate how BNL's premiere facility was able to demonstrate to interested parties that care had been taken to implement technological and administrative controls to minimize environmental impacts, while at the same time reduce the applicability of regulatory requirements to their operations

    2013-01-01

    In the aftermath of the March 2011 accident at Japan's Fukushima Daiichi nuclear power plant, the future contribution of nuclear power to the global energy supply has become somewhat uncertain. Because nuclear power is an abundant, low-carbon source of base-load power, it could make a large contribution to mitigation of global climate change and air pollution. Using historical production data, we calculate that global nuclear power has prevented an average of 1.84 million air pollution-related deaths and 64 gigatonnes of CO2-equivalent (GtCO2-eq) greenhouse gas (GHG) emissions that would have resulted from fossil fuel burning. On the basis of global projection data that take into account the effects of the Fukushima accident, we find that nuclear power could additionally prevent an average of 420 000-7.04 million deaths and 80-240 GtCO2-eq emissions due to fossil fuels by midcentury, depending on which fuel it replaces. By contrast, we assess that large-scale expansion of unconstrained natural gas use would not mitigate the climate problem and would cause far more deaths than expansion of nuclear power.

    Dental caries is the most common chronic disease of childhood. Cariogram is a well-recognized algorithm-based software program based on different caries-related risk factors and intended to aid clinicians in performing more objective and consistent dental caries risk assessments. This type of approach precedes the diagnosis of caries and allows the dentist to identify at-risk patients and then take appropriate preventive measures before caries develop further. One of the etiological factors favoring the development of dental caries is the mutans streptococci. These acidogenic dental plaque inhabitants can be effectively antagonized by the activity of bacteriocins released by the probiotic Streptococcus salivarius M18 (salivarius M18). Moreover, salivarius M18 after colonizing the human oral mucosa produces the enzymes dextranase and urease that are able to counteract plaque formation and saliva acidity, respectively. Seventy-six subjects at high risk of dental caries were randomized and then either treated or not treated for 90 days with an oral formulation containing the oral probiotic salivarius M18 (Carioblis(®)). The results indicate that the use of salivarius M18 increases the chances of avoiding new dental caries development in children, and its application could be proposed as a new tool in the dentist's armory to be adopted in subjects considered at high risk on the basis of their Cariogram outcome.

Methods The TROPIC project draws on the concept of ‘knowledge exchange’ between policy developers (individuals; organisations and researchers to deliver a knowledge broking programme that maps policy environments, conducts workshops on evidence-informed policy making, supports the development of evidence-informed policy briefs, and embeds evidence-informed policy making into organisational culture. Recruitment of government and nongovernment organisational representatives will be based on potential to: develop policies relevant to obesity, reach broad audiences, and commit to resourcing staff and building a culture that supports evidence-informed policy development. Workshops will increase awareness of both obesity and policy cycles, as well as develop participants’ skills in accessing, assessing and applying relevant evidence to policy briefs. The knowledge-broking team will then support participants to: 1 develop evidence-informed policy briefs that are both commensurate with national and organisational plans and also informed by evidence from the Pacific Obesity Prevention in Communities project and elsewhere; and 2 collaborate with participating organisations to embed evidence-informed policy making structures and processes.

    The development and validation of a caries prediction model comprising 13 sociodemographic and dental examination variables on Grade 1 and Grade 5 children in the National Preventive Dentistry Demonstration Program are described. The objective was to derive a method of predicting children at high risk to caries early in order that preventive measures might be undertaken. True high risk children were defined in two ways: highest 25% of children based on their 4-yr DMFS increment, and their total DMFS score at the end of the study. In both cases, children predicted to be at high risk were defined as the 25% with the highest discriminant score. Discriminant function and logistic regression analyses were used to determine the extent to which the 13 variables collectively discriminated between true high risk and non-high risk children so defined. Sensitivity was approximately 0.50 and specificity around 0.82, using the 4-yr increment as the criterion for defining true high risk, and approximately 0.64 and 0.88, respectively, using the final DMFS score for defining true high risk.

    Full Text Available Objective: To know the beliefs about tooth decay and oral hygiene in adolescents from the Department of Valle of Cauca, Colombia. Methods: The Health Belief Model was used in a descriptive study in 38 out of 42 municipalities of the Department. The sample of 5400 adolescent students from public and private high schools was selected trough a probabilistic, stratified, tri-stage cluster sampling. A structured questionnaire made of 47 items related to the variables of the study was used. Results: Respecting the etiology, 65% beliefs that dental caries is due to bad oral hygiene, 18% due to bacteria, 7% associates it to the sugar consumption and 10% didn’t know; 41% referred that they have had tooth decay already, 14% said that had decay at moment, 37% did not have perceived history of decay; 99.8% answered that they do bush their teeth, the brushing frequency had a median of 3 times per day; 55% uses dental floss and 51% mouth wash; 14% referred that never have visited the dentist and 27% said that visited him/her 7 months ago or more. Conclusions: The use of the Health Belief Model allowed know the basic beliefs about tooth decay and oral hygiene in adolescents of the Valley of Cauca. Beliefs and preventive practices of the participants are not favorable. It is necessary to design preventive interventions for improving perceptions and reducing the presence and effects of the dental caries.

    Full Text Available Aim. To determine the prevalence of dental caries among a representative sample of preschool children (4-5 years old who were accompanied by their parents to the dental centre of the Arab American University in Jenin whether they come seeking dental treatment or as visitors with adult patients. Materials and Methods. 1376 children of both sexes were investigated by three calibrated and trained examiners for dental caries using the dmft index according to the WHO method. Results. 76% of the studied children have already experienced dental caries at the age of 4-5 years (1046 children. The mean dmft score was found to be 2.46 while the other 24% of children were caries-free. There was no significant difference in caries prevalence between boys and girls (77.2% versus 74.6%. Children of highly educated and college graduated mothers were found to have more fillings (restored teeth in comparison to those who belong to mothers who did not finish their secondary (high school education. Conclusion. The number of caries-free children in northern Palestine is still far from numbers found in developed countries. There is a real need to make improvements at the level of parents dental health education, application of preventive measures, and dietary habits among preschool children.

    Prevention of childhood obesity is a global priority. The school setting offers access to large numbers of children and the ability to provide supportive environments for quality physical activity and nutrition. This article describes Project Energize, a through-school physical activity and nutrition programme that celebrated its 10-year anniversary in 2015 so that it might serve as a model for similar practices, initiatives and policies elsewhere. The programme was envisaged and financed by the Waikato District Health Board of New Zealand in 2004 and delivered by Sport Waikato to 124 primary schools as a randomised controlled trial from 2005 to 2006. The programme has since expanded to include all 242 primary schools in the Waikato region and 70 schools in other regions, including 53,000 children. Ongoing evaluation and development of Project Energize has shown it to be sustainable (ongoing for >10 years), both effective (lower obesity, higher physical fitness) and cost effective (one health related cost quality adjusted life year between $18,000 and $30,000) and efficient ($45/child/year) as a childhood 'health' programme. The programme's unique community-based approach is inclusive of all children, serving a population that is 42% Māori, the indigenous people of New Zealand. While the original nine healthy eating and seven quality physical activity goals have not changed, the delivery and assessment processes has been refined and the health service adapted over the 10 years of the programme existence, as well as adapted over time to other settings including early childhood education and schools in Cork in Ireland. Evaluation and research associated with the programme delivery and outcomes are ongoing. The dissemination of findings to politicians and collaboration with other service providers are both regarded as priorities. PMID:26809555

    Full Text Available Background: An anti-cariogenic diet containing probiotics can be effective in caries prevention. This animal study compared the effects of milk and yogurt on Streptococcus sobrinus counts and caries score. Materials and Methods: A total of 36 male rats were infected with S. sobrinus (27,607 and divided into three groups. Group A and B received 200 mL of milk and 100 g of yogurt per day, respectively, and a control group received 2.5 mL of NCP number 2 diet twice daily for 21 days. After killing the animals, their lower left jaws were removed and sonicated to quantify the colonies of S. sobrinus. Dental caries was scored using Keyes technique. Data were analyzed using ANOVA and Kruskal-Wallis, Mann-Whitney and Wilcoxon-Signed Rank tests. Statistical significance was set at P < 0.05. Results: The mean (±standard error of the mean of S. sobrinus colonies in the milk, yogurt and control groups were determined at 119666.67 (±20733, 46416.666 (±12846 and 163,250 (±33493, respectively. Microbial counts decreased in the yogurt group compared with the milk and control groups (P = 0.004 and P = 0.000; respectively. There were significant differences between caries scores of smooth surfaces in the milk and yogurt groups compared with the control group (P = 0.000 and P = 0.000, respectively. Both milk and yogurt significantly reduced caries score of fissured surfaces compared with controls (P = 0.004 and P = 0.000, respectively. Conclusion: Considering the limitations of this study, yogurt administration reduces S. sobrinus counts. In addition, yogurt and milk regimens reduce the caries scores of smooth and fissured surfaces.

  5. Amoco-US Environmental Protection Agency, pollution prevention project, Yorktown, Virginia: Surface water data

    International Nuclear Information System (INIS)

    The report summarizes the surface water sampling program at the Amoco Refinery at Yorktown, Virginia. This was undertaken as a part of the joint project between Amoco Corporation and the United States Environmental Protection Agency to review pollution prevention alternatives at a petroleum refinery. The surface water data provides a snapshot of surface water pollutant generation and discharge from the refinery. Different process units contribute to the total wastewater flow of 460 GPM in the refinery. Water in the ditch system, which is non-process water, is free of organic contamination. Oil and grease, phenols, ammonia and sulfides are the significant components measured in the process wastewater. The concentrations of organics in most water streams leaving the individual process units are relatively low, in the 1-5 parts per million (ppm) range. A few individual streams such as the crude desalter brine and tank water draws have high pollutant loadings. Concentrations of metals in the refinery wastewater are very low. The wastewater treatment plant is very effective in reducing the pollutant loading in the water with overall removal efficiencies greater than 99% for most organics and inorganics

    During the decades after the start of the North Karelia Project in 1971, cardiovascular diseases and related noncommunicable diseases have emerged as the greatest global public health burden. The prevention and control of these diseases have thus become a major challenge and target for global public health, as emphasized by the Political Declaration of the United Nations (UN) General Assembly in 2011. The experiences and results of the North Karelia Project have accordingly received much international attention and have in many ways contributed to the international work in the area, including the strategies and programs of the World Health Organization. The experience of the Project shows the great potential of population-based prevention of cardiovascular diseases and other noncommunicable diseases and that influencing lifestyles related to heart health with comprehensive health promotion and national policies is the cost-effective and sustainable way to improve contemporary public health.

  20. Caries like lesion initiation in sound enamel following CW CO2 laser irradiation: an in vitro study

    International Nuclear Information System (INIS)

    This Study aimed to asses the caries - preventive potential of various CW CO2 laser parameters, and to explore the effect of the laser power density, and the exposure time on the varies inhibition activity. Materials and Methods: Extracted human premolar teeth were irradiated with three different power densities (7.95, 15.9 and 31.8) W/Cm2 for three different exposure times (0.2, 0.4 and 0.8) sec of 10.6 μm CW CO2 laser. All teeth were subjected to caries like lesion formation by 3.5 pH lactic acid for 21 days. The teeth after that were sectioned into ground cross section and the lesion depths were measured using a graticule polarizing microscope. CW CO2 laser preventive treatments inhibit caries like lesion progression up to 44%. This effect was improved with: (1) Increased power density for each of the three exposure times. (2) Decreased exposure time for each of the three power densities within the limits of the previously listed laser parameters. Conclusion: (1) short exposure time of CW CO2 laser results in a significant inhibition of the enamel caries like lesion formation. (2) The inhibitory effect depends upon the power density and the exposure time of the laser beam. (3) The optimal CW CO2 laser parameters used for caries inhibition purpose is achieved with approximately 30 W/Cm2 power density and 0.2 sec exposure time. (author)

  1. Clinical diagnosis of dental caries: a European perspective.

    Science.gov (United States)

    Pitts, N B

    2001-10-01

    The aim of this paper is to provide a broad international perspective on aspects of the RTI/UNC systematic review, to introduce relevant literature not cited, and to make recommendations for clinical practice education and research suggested by the evidence. Clinical caries diagnosis represents the foundation on which the answers to most of the consensus questions will be based. This paper highlights needs for being clear about definitions and nomenclature; understanding the importance of the concepts underlying the D1 and D3 diagnostic thresholds used widely within the RTI/UNC Review; and appreciating that the diagnostic challenge now faced by clinicians is significant and is becoming more complex as the presentation and distribution of the disease changes over time and the range of preventive and operative treatment options expands. A series of recommendations informed by the evidence are made, including a rather contentious issue for many clinicians concerning the lack of evidence supporting the continued use of a sharp explorer as a diagnostic tool for primary caries diagnosis. This practice should be discontinued as it may cause some harm to the patient and yet fails to provide a significant balancing diagnostic benefit. Finally, it is suggested that dentistry should learn from the developing evidence base in medicine on how best to disseminate the findings of reviews and promote appropriate changes in clinical practice.

    Full Text Available 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. 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.

    Full Text Available The emphasis currently given to new technologies for enamel remineralization suggests that the changes in the understanding of the dental caries disease, which occurred in the last century, were either not yet adopted or were forgotten. Just like in the past, when the disease was "treated" by restoring cavities, there is presently a misunderstanding on the concept of incipient lesion remineralization. The aim of this paper was to review some concepts about caries, the natural phenomenon of enamel remineralization and the effect of fluoride (F on it, and also to discuss the clinical relevance of remineralizing products recently launched in the marketplace aiming to "treat early caries lesions".

    Full Text Available Abstract Background The rising burden of obesity in Tonga is alarming. The promotion of healthy behaviours and environments requires immediate urgent action and a multi-sectoral approach. A three-year community based study titled the Ma'alahi Youth Project (MYP conducted in Tonga from 2005-2008 aimed to increase the capacity of the whole community (schools, churches, parents and adolescents to promote healthy eating and regular physical activity and to reduce the prevalence of overweight and obesity amongst youth and their families. This paper reflects on the process evaluation for MYP, against a set of Best Practice Principles for community-based obesity prevention. Methods MYP was managed by the Fiji School of Medicine. A team of five staff in Tonga were committed to planning, implementation and evaluation of a strategic plan, the key planks of which were developed during a two day community workshop. Intervention activities were delivered in villages, churches and schools, on the main island of Tongatapu. Process evaluation data covering the resource utilisation associated with all intervention activities were collected, and analysed by dose, frequency and reach for specific strategies. The action plan included three standard objectives around capacity building, social marketing and evaluation; four nutrition; two physical activity objectives; and one around championing key people as role models. Results While the interventions included a wide mix of activities straddling across all of these objectives and in both school and village settings, there was a major focus on the social marketing and physical activity objectives. The intervention reach, frequency and dose varied widely across all activities, and showed no consistent patterns. Conclusions The adolescent obesity interventions implemented as part of the MYP program comprised a wide range of activities conducted in multiple settings, touched a broad spectrum of the population (wider

    2007-07-01

    Full Text Available Abstract Background Economic theory and limited empirical data suggest that costs per unit of HIV prevention program output (unit costs will initially decrease as small programs expand. Unit costs may then reach a nadir and start to increase if expansion continues beyond the economically optimal size. Information on the relationship between scale and unit costs is critical to project the cost of global HIV prevention efforts and to allocate prevention resources efficiently. Methods The "Prevent AIDS: Network for Cost-Effectiveness Analysis" (PANCEA project collected 2003 and 2004 cost and output data from 206 HIV prevention programs of six types in five countries. The association between scale and efficiency for each intervention type was examined for each country. Our team characterized the direction, shape, and strength of this association by fitting bivariate regression lines to scatter plots of output levels and unit costs. We chose the regression forms with the highest explanatory power (R2. Results Efficiency increased with scale, across all countries and interventions. This association varied within intervention and within country, in terms of the range in scale and efficiency, the best fitting regression form, and the slope of the regression. The fraction of variation in efficiency explained by scale ranged from 26% – 96%. Doubling in scale resulted in reductions in unit costs averaging 34.2% (ranging from 2.4% to 58.0%. Two regression trends, in India, suggested an inflection point beyond which unit costs increased. Conclusion Unit costs decrease with scale across a wide range of service types and volumes. These country and intervention-specific findings can inform projections of the global cost of scaling up HIV prevention efforts.

    Full Text Available Mushroom-derived natural products have been used to prevent or treat cancer for millennia. In this study, we evaluated the anticancer effects of CARI (Cell Activation Research Institute III, which consists of a blend of mushroom mycelia from Phellinus linteus grown on germinated brown rice, Inonotus obliquus grown on germinated brown rice, Antrodia camphorata grown on germinated brown rice and Ganoderma lucidum. Here, we showed that CARI III exerted anti-cancer activity, which is comparable to Dox against melanoma in vivo. B16F10 cells were intraperitoneally injected into C57BL6 mice to develop solid intra-abdominal tumors. Three hundred milligrams of the CARI III/kg/day p.o. regimen reduced tumor weight, comparable to the doxorubicin (Dox-treated group. An increase in life span (ILS% = 50.88% was observed in the CARI III-administered group, compared to the tumor control group. CARI III demonstrates anti-proliferative activity against B16F10 melanoma cells through inducing G0/G1 cell cycle arrest. CARI III inhibits the expression of cyclin D1, CDK4 and CDK2 and induces p21. Therefore, CARI III could be a potential chemopreventive supplement to melanoma patients.

    Background and aims. Early Childhood Caries (ECC) is a public health problem with biological, social and behavioural determinants and the notion that the principal etiology is inappropriate feeding modalities is no longer tenable. Hence this study was undertaken to assess the relationship between ECC and socio-demographic factors, dietary habits, oral hygiene habits and parental characteristics. Materials and methods. The study involved a dental examination of 1400 children aged 0-71 months, recording caries using Gruebbel's deft index and a structured questionnaire to interview parents or caretakers. The tabulated data was statistically analyzed using t-test and ANOVA at 5% level of significance. Results. The variables significantly associated with ECC were age (PPPPPPPPP>0.05). Conclusion. ECC is preventable and manageable with proper information and skills. It is important for healthcare professionals, family physicians and parents to be cognizant of the involved risk factors as their preventive efforts represent the first line of defense.

    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.

    2007-01-01

    This article has taken a medical approach toward the understanding and managing of dental caries. Caries has been defined as a point in a person's life when there is an imbalance between protective and pathologic factors such that the process of demineralization of tooth structure by acid from bacteria in the tooth biofilm exceeds the patient's ability to remineralized tooth structure. The patient diagnosed with caries is out of balance. Caries is a diagnosis of a person. People have caries, teeth have lesions. Caries lesion detection, classification, and analysis are done at the level of the tooth surface. Caries is a process in time. Today we establish a diagnosis. For the future we establish a prediction. Patients can be diagnosed as caries active, caries balanced, or caries undetermined. For an improved treatment plan, future risk and prognosis assessments are accomplished by classifying all patients as either low, moderate, or high risk. A combination of diagnosis and risk or prognosis assessment leads to five treatment groups, each with an appropriate protocol for managing the disease process. The five protocols follow from the use of the four-step medical model for caries management. In the end, there are two treatment plans for these patients: a restorative therapy plan that treats the holes and a disease management plan that treats the disease. Surgical treatment does not manage the disease. Today we are managing tooth decay with medicine instead of a drill. PMID:18051341

    2012-01-01

    Full Text Available Patients can become entirely edentulous (without teeth due to severe malnutrition, genetic defects such as dentinogenesis imperfect, periodontal disease, age, tooth decay or traumas. Sealants, however, are very thin and only fill the pits and grooves of molar teeth. Sealants keep germs and food particles out of the grooves by covering them with a safe plastic coating. Denture sealant cream is used to keep dentures in place during normal daily activity. When properly placed, sealants provide a physical barrier between the dental enamel and the oral environment shielding the tooth surface from acid challenge. Dental sealants are highly effective in preventing dental caries that occur on the surfaces of teeth that have pits and fissures. Sealants can save time, money, and the discomfort sometimes associated with dental fillings.

    Dental caries is one of the most common chronic and multifactorial diseases affecting the human population. The appearance of a caries lesion is determined by the coexistence of three main factors: acidogenic and acidophilic microorganisms, carbohydrates derived from the diet, and host factors. Socio-economic and behavioral factors also play an important role in the etiology of the disease. Caries develops as a result of an ecological imbalance in the stable oral microbiom. Oral microorganisms form dental plaque on the surfaces of teeth, which is the cause of the caries process, and shows features of the classic biofilm. Biofilm formation appears to be influenced by large scale changes in protein expression over time and under genetic control Cariogenic microorganisms produce lactic, formic, acetic and propionic acids, which are a product of carbohydrate metabolism. Their presence causes a decrease in pH level below 5.5, resulting in demineralization of enamel hydroxyapatite crystals and proteolytic breakdown of the structure of tooth hard tissues. Streptococcus mutans, other streptococci of the so-called non-mutans streptococci group, Actinomyces and Lactobacillus play a key role in this process. Dental biofilm is a dynamic, constantly active metabolically structure. The alternating processes of decrease and increase of biofilm pH occur, which are followed by the respective processes of de- and remineralisation of the tooth surface. In healthy conditions, these processes are in balance and no permanent damage to the tooth enamel surface occurs. PMID:25115106

Cariogram is a well-recognized algorithm-based software program based on different caries-related risk factors and intended to aid clinicians in performing more objective and consistent dental caries risk assessments. This type of approach precedes the diagnosis of caries and allows the dentist to identify at-risk patients and then take appropriate preventive measures before caries develop further. One of the etiological factors favoring the development of dental caries is the mutans streptococci. These acidogenic dental plaque inhabitants can be effectively antagonized by the activity of bacteriocins released by the probiotic Streptococcus salivarius M18 (salivarius M18. Moreover, salivarius M18 after colonizing the human oral mucosa produces the enzymes dextranase and urease that are able to counteract plaque formation and saliva acidity, respectively. Seventy-six subjects at high risk of dental caries were randomized and then either treated or not treated for 90 days with an oral formulation containing the oral probiotic salivarius M18 (Carioblis®. The results indicate that the use of salivarius M18 increases the chances of avoiding new dental caries development in children, and its application could be proposed as a new tool in the dentist's armory to be adopted in subjects considered at high risk on the basis of their Cariogram outcome.

    The objective of the present work is to identify the set of prenatal and familial factors that contribute to dental caries of first permanent molars in preschool and young schoolchildren, which will make it possible to determine a high-risk group that should be considered for special preventive measures. This study contributes to the evidence for the multifactorial nature of dental caries. Material was collected during a 2009-2010 study conducted in randomly selected schools and kindergartens in the city of Łódź (Poland). Only children with first permanent molars present were considered for the analysis, which limited the database to 1131 children. Dental examinations were accompanied by a questionnaire completed by the parents, covering items pertaining to prenatal and familial determinants. The present study shows that there are significant differences in the prevalence of caries in first molars between children of different ages (5-13 lat) and that no such differences exist between boys and girls. The prenatal and familial factors conducive to caries include maternal education level (OR=0.55), mode of delivery (OR=0.63) and birth order (OR=0.63). Mothers' smoking habit is also associated with increased caries prevalence in children. Caries prevention should already begin during the prenatal period primarily in respect of mothers with lower educational attainment who are pregnant with a second or subsequent child. PMID:26749439

  1. ROC analysis of acid demineralized artificial caries

    International Nuclear Information System (INIS)

    This study is designed to determine the artificial incipient proximal caries lesion detectability by dentists on Ektaspeed Plus film using ROC analysis. Sixteen premolars and 30 molars, which have 52 proximal caries-like demineralized lesions using acid-gel technique were added to 20 sound premolars and 30 sound molars to make 24 plaster blocks. Each block with 4 teeth and 6 contacting proximal surfaces was placed in an optical bench to take 12 bitewing radiographs with Ektaspeed Plus film. Thirty-six dentists acted as observers to evaluated the proximal lesions using five rating scales for ROC analysis. They were also asked to determine the presence or absence of the proximal caries. The true status of the proximal caries was established by the consensus of three oral and maxillofacila radiologists. For evaluation of intra-observer agreement, 9 dentist reread the radiographs at an interval of 1 month. The Pearson correlation coefficient for the intra-observer agreement was 0.746 (good agreement). Ten observer's data set were degenerated. The mean area under ROC curve from 26 observers was 0.806 and standard deviation was 0.061. The sensitivity and the specificity of the binary response were 0.17 (SD=0.11) and 0.78 (SD=0.17) respectively. The binary response only reveal a single values of sensitivity and the specificity. The ROC analysis to assess the diagnostic accuracy in caries detection, which producing estimates of sensitivities for all specifities, yield more comprehensive measures of diagnostic performance than single values for sensitivity and specificity.

    Full Text Available Background: Habits formed in childhood dictate lifestyle choices made as adults. These encompass both oral hygiene and dietary habits which in turn affect dental caries status. Children largely acquire these habits from modeling/observing parents and other family members. Aim: The purpose of this study was to assess the caries status of 5-year-olds, and evaluate associations between dental caries and family-related factors. Materials and Methods: A cohort of 400 children were examined for dental caries using the WHO criteria. Parents were interviewed using a self-structured questionnaire to collect data with regard to variables under evaluation. Statistical analysis: Collected data was subjected to descriptive analysis using the SPSS 12.0 version. Risk factor association with dental caries was investigated using a stepwise logistic regression analysis with P-values 0 were: Mother with low basic education (OR = 1.3, higher number of siblings (OR = 1.4, high snacking frequency (OR = 2.0, parental inability to control sugar consumption (OR = 1.0 parental laxness about the child′s tooth brushing (OR = 1.5, parents brushing their own teeth less than twice daily (OR= 2.0 and unassisted brushing by the child (OR = 1.8. Conclusion: It is thus mandatory to focus on parents′ education level, attitudes and family-structure when planning preventive programs for young children.

    ABSTRACT Background: Children who have severe early childhood caries (S-ECC) weigh significantly less than caries-free children. The association between S-ECC and weight suggests that its timely treatment at early stages may preserve general health, in addition to preventing pain and infection. Objective: This study was conducted to evaluate whether children with untreated S-ECC had lower weight and height as compared with children with low caries and to evaluate whether full mouth rehabilitation of children with S-ECC resulted in the phenomenon of catch-up growth. Materials and methods: The weight and height of children with noncontributory medical histories and S-ECC (3-6 years) were compared with caries-free children, before and 6 months after full mouth dental rehabilitation. Results: Prior to dental rehabilitation, children with S-ECC had significantly less weight and height than their comparison counterparts (p < 0.001). Following therapeutic intervention, the test group children exhibited catch-up growth in relation to weight, as there was no significant difference in the body weight of the test and control groups (p = 0.171). Conclusion: Comprehensive full mouth rehabilitation of children with S-ECC results in catch-up growth, thus improving the overall health of the child.

  8. Bio-modification approach for novel dentine caries management by Galla chinesis extract and microbial transglutaminase

    Full Text Available Introduction: Dental caries still remains one of the most prevalent diseases worldwide. Unlike enamel caries which can be restored mainly by modulating mineral balance, the dentine caries are characterized with irreversible proteolytic disintegration of organic matrices, highlighting an urgent need to seek novel management strategies. Bio-modification of dentine matrix has been proposed as a novel and alternative approach to enhancing its biochemical and biomechanical properties. The resultant chemical stability and mechanic durability are specifically desirable for prevention and restoration of dentine caries. However, conventional cross linking agents, e.g. glutaraldehyde, formaldehyde,are unsuitable for clinical use due to marked cytotoxicity or instability over time. The Hypothesis: Previous studies revealed that Galla chinesis extract (GCE could inhibit cariogenic microbes and positively modulate enamel de/remineralization balance, and the mechanism was directed to the polyphenols-organic matrix interaction involving hydrogen, covalent, ionic bonding and hydrophobic processes. Microbial transglutaminase (mTGase could induce crosslinks between peptide chains and improve functional properties of food proteins by catalyzing an acyl transfer reaction through ε - (γ-glutamyl lysine (GL bonds. Given the high organic content in dentine and universal reaction nature of GCE and mTGase, we put forward a hypothesis that these two natural products may serve as novel biocompatible bio-modifiers to improve biochemical and biomechanical properties of dentine matrices. Evaluation of the Hypothesis: The validation of our hypothesis will provide profound insights updating current therapeutic strategies against dentine caries, and pioneer novel approaches for biocompatible bio-modification of dentine matrices. Specifically, GCE and mTGase can be integrated into the root canal irrigating and dentine boding procedures, where they may generate beneficial

    Full Text Available Abstract Background The objective of this study was to measure the validity and reliability of a multifactorial Risk Factor Model developed for use in predicting future caries risk in Nevada adolescents in a public health setting. Methods This study examined retrospective data from an oral health surveillance initiative that screened over 51,000 students 13-18 years of age, attending public/private schools in Nevada across six academic years (2002/2003-2007/2008. The Risk Factor Model included ten demographic variables: exposure to fluoridation in the municipal water supply, environmental smoke exposure, race, age, locale (metropolitan vs. rural, tobacco use, Body Mass Index, insurance status, sex, and sealant application. Multiple regression was used in a previous study to establish which significantly contributed to caries risk. Follow-up logistic regression ascertained the weight of contribution and odds ratios of the ten variables. Researchers in this study computed sensitivity, specificity, positive predictive value (PVP, negative predictive value (PVN, and prevalence across all six years of screening to assess the validity of the Risk Factor Model. Results Subjects' overall mean caries prevalence across all six years was 66%. Average sensitivity across all six years was 79%; average specificity was 81%; average PVP was 89% and average PVN was 67%. Conclusions Overall, the Risk Factor Model provided a relatively constant, valid measure of caries that could be used in conjunction with a comprehensive risk assessment in population-based screenings by school nurses/nurse practitioners, health educators, and physicians to guide them in assessing potential future caries risk for use in prevention and referral practices.

  10. The effect of right or left handedness on caries experience and oral hygiene

    Full Text Available Background: There is an indisputable relationship between tooth decay and oral hygiene. Caries can only be prevented by keeping tooth decay at bay. In several prophylactic methods, brushing is the most important. Brushing efficiency is directly related to an individuals′ manual dexterity. Objective: To investigate whether there were differences in oral hygiene and caries prevalence between right- and left-handers. Materials and Methods: Forty-six elementary school students were included in the study. The subjects were 30 males and 16 females, ranging in age from 11 to 13 years. Handedness was ascertained by using the Edinburgh Handedness Scale. All students were examined intraorally. During this examination, the necessary values to determine oral hygiene status and to determine caries prevalence were recorded. Results: It was observed that subjects who used their right hands were in a better position in terms of oral hygiene than those using the left (P < 0.01. In terms of caries prevalence, however, averages for right-handed individuals were lower than those for left-handed subjects, although the difference was not statistically significant. Conclusions: It can be stated that the right-handed individuals have better oral hygiene and the lower incidence of caries because of their better manual dexterity and brush efficiency. So, dentists should consider better manual dexterity and brush efficiency in right-handed individuals before treatment planning. However, future well-designed neurologic studies involving larger numbers of subjects will be necessary to confirm the findings of this study and to understand more about the effects of handedness on oral hygiene performance.

  11. Emerging technologies for diagnosis of dental caries: The road so far

    2009-05-01

    It is now universally recognized that the development of new technologies for early detection and quantitative monitoring of dental decay at an early stage of formation could provide health and economic benefits ranging from timely preventive interventions to reduction in the time required for clinical trials of anticaries agents. The use of technologies as adjunct to clinical visual examination for caries diagnosis will facilitate preventive care in dentistry to lower treatment cost as well as reduce the cost and time for testing potential anticaries agents. This article describes the various technologies available to aid the dental practitioners in detecting dental caries at the earliest stage of its formation, assessing the activities of the detected carious lesion, and quantitatively or qualitatively monitoring of the lesion over time. The need and the importance of these technologies were also discussed. The data discussed are primarily based on published scientific studies and reviews from case reports, clinical trials, and in vitro and in vivo studies. References have been traced manually by MEDLINE® or through manufacturer's websites. While some of the devices are fully developed and commercially available, others are still under development. The devices vary in their modes of action as well as their capability as caries diagnostic aids. It is clear that the differences in caries presentations and behavior in different anatomical sites make it unlikely that any one diagnostic modality will have adequate sensitivity and specificity of detection of carious lesions for all sites; a combination of diagnostic tools will help us diagnose lesions earlier and detect failing restorations sooner, all to avoid more costly, destructive dental procedures and truly take dentistry into the preventive rather than the reactive mode.

    This paper describes the dental health status of Italian 4-year-olds in 2004/2005 and analyzes the association between caries in preschool children and some background characteristics in children and parents. Caries was recorded according to WHO criteria. 5,538 subjects were examined. Information on the children's and their parents' social, behavioral, ethnic and demographic status was obtained through a series of closed questions. Bivariate analysis was performed to investigate the association between caries and background characteristics. The probability of being an extra zero for the dmfs index was estimated via the zero-inflated negative binomial regression model (ZINB). 78.4% (95% CI = 77.2-79.6) of the children were caries-free. The national mean dmfs index was 1.36 (95% CI = 1.15-1.57), ranging from 1.22 (95% CI = 1.03-1.42) in the Italian North-East to 1.73 (95% CI = 0.83-2.63) in the South section. Significant bivariate associations between caries experience and risk factors were observed for parents' nationality (not Italian vs. Italian: p preterm birth (yes vs. no: p = 0.011), prolonged breastfeeding (13 months: p = 0.038) and early tooth eruption (fathers with a high educational level showed a probability of being an extra zero of 0.22. The results suggest a need to plan preventive programs to reduce oral health disparities among Italian preschool children, based on educational intervention with parents and children concerning oral health and caries prevention.
