    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 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.

    Full Text Available Abstract Background Dental caries (decay during childhood is largely preventable however it remains a significant and costly public health concern, identified as the most prevalent chronic disease of childhood. Caries in children aged less than five years (early childhood caries is a rapid and progressive disease that can be painful and debilitating, and significantly increases the likelihood of poor child growth, development and social outcomes. Early childhood caries may also result in a substantial social burden on families and significant costs to the public health system. A disproportionate burden of disease is also experienced by disadvantaged populations. Methods/Design This study involves the establishment of a birth cohort in disadvantaged communities in Victoria, Australia. Children will be followed for at least 18 months and the data gathered will explore longitudinal relationships and generate new evidence on the natural history of early childhood caries, the prevalence of the disease and relative contributions of risk and protective biological, environmental and behavioural factors. Specifically, the study aims to: 1. Describe the natural history of early childhood caries (at ages 1, 6, 12 and 18 months, tracking pathways from early bacterial colonisation, through non-cavitated enamel white spot lesions to cavitated lesions extending into dentine. 2. Enumerate oral bacterial species in the saliva of infants and their primary care giver. 3. Identify the strength of concurrent associations between early childhood caries and putative risk and protective factors, including biological (eg microbiota, saliva, environmental (fluoride exposure and socio-behavioural factors (proximal factors such as: feeding practices and oral hygiene; and distal factors such as parental health behaviours, physical health, coping and broader socio-economic conditions. 4.

    The early childhood caries affect primary dentition before the eruption of the permanent teeth. It is set to extended use of a bottle containing fermentable carbohydrates. The early childhood caries is not only a dental disease: it is a social, cultural and behavioral condition that reflects the practices and beliefs around the child. Swiss data indicate that in aged 2 children, one of for could be affected by this devastating oral disease, mainly in vulnerable populations. The primary care physician has an important role in the screening of preschool children, in determining the risk level of the child for early childhood caries. Physicians can advise families, especially pregnant women, about preventive measures and behavior, leading to a dramatic drop of early childhood caries prevalence. PMID:22545498

    Full Text Available Background:Little research has been carried out on whether the parental stress affects children′s oral health in general and dental caries in particular. This study aimed to investigate the association be-tween parental stress and early childhood caries (ECC. Methods: A cross-sectional study was designed that included 250 children of 4-6 year-old; 127 ones attended the pediatric department of Isfahan School of Dentistry who had early childhood caries and a comparison group of 123 caries free children attended five kindergartens and pre-schools in Isfahan city. Clinical examinations were conducted to evaluate the caries status. The parents of the two study groups completed the self-administrated long form of the Parenting Stress Index questionnaire. De-tails of their socio-demographic status were gathered too. The collected data were analyzed by SPSS version 11.5. The nonparametric Mantel-Haenszel test for correlation statistics was used to determine bivariate associations between total parenting stress and their domains scores in the two groups; i.e., those with early childhood caries and the caries free group. Results: Mean score of PSI in the early childhood caries and caries free group were 286.66 ± 66.26 and 273.87 ± 31.03, respectively. There was not any significant relationship between total parental stress and ECC. The scores of the following domains of PSI demonstrated significant differences between ECC and CF groups: child reinforcement, child distractibility, child deficit attention, life stress and relationship with spouse (P = 0.01, 0.01, 0.001, 0.005 respectively. Conclusion: Findings of this study did not show any significant association between total parenting stress score and prevalence of early childhood caries.

    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.

    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.

    This cross-sectional study empirically tested a theoretical model of pathways and inter-relationships among community, family, and individual determinants of childhood dental caries in a sample of 630, 6-year-old children from the Netherlands. Children's decayed, missing, and filled teeth (dmft) scores were extracted from dental records. A validated parental questionnaire was used to collect data on sociodemographic characteristics, psychosocial factors, and oral hygiene behaviours. Data on neighbourhood quality were obtained from the Dutch Central Bureau of Statistics. Structural equation modelling indicated that the model was valid after applying a few modifications. In the revised model, lower maternal education level was related to poorer family organization, lower levels of social support, lower dental self-efficacy, and an external dental health locus of control. These, in turn, were associated with poorer oral hygiene behaviours, which were linked to higher levels of childhood dental caries. In addition, lower maternal education level and poorer neighbourhood quality were directly associated with higher caries levels in children. This model advances our understanding of determinants of childhood dental caries and the pathways in which they operate. Conception of these pathways is essential for guiding the development of caries-preventive programmes for children. Clues for further development of the model are suggested.

    Full Text Available Background and Aims: Improper feeding is one of the most important etiologic factors in early childhood caries (ECC. In some clinical trials, breast feeding (BF is mentioned as a causing factor in ECC. Results in this topic are different or even controversial. It is vital that all general advices given out are consistent with general health education messages. The aim of this study was to conduct a systematic review on the relationship between breast feeding and early childhood caries. Materials and Methods: Articles, guidelines, related books, and specific databases such as SID, PubMed, Scirus, Elsevier, American Association of Pediatric Dentistry (AAPD, American Association of Pediatrics (AAP and American Dental Association (ADA were searched for related topics cited since 1990. Early childhood caries definition, breast feeding and other variables such as sample size, study location and study design were analyzed.Results: According to data analysis, there was a lack of methodological consistency and inconsistent definitions of ECC and BF in the literature making it difficult to draw conclusions. Results about relationship between prolonged BF and ECC were inconclusive. There was a positive relationship between nocturnal BF and ECC. A history of BF did not have any effect on the caries incidence.Conclusion: Because of the role of breast feeding in children's health, it is important to inform the parents about the possibility of dental caries due to nocturnal breast feeding.

    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.

    Beyond the biological risk factors of early childhood caries (ECC) is child temperament. This study aimed to investigate the relationship of ECC to different traits of child temperament, directly and indirectly through the nutritional and oral hygiene habits. Through a multi-stage sampling, 373 kindergarten children aged 18-36 months participated in this study. The primary caregivers filled in the Early Childhood Behaviour Questionnaire (ECBQ) and a checklist containing demographic data and the dietary and oral hygiene habits of the children. Children were examined for dental caries. The frequency of ECC was 41.14%. With 18 aspects of a child's temperament under consideration, attentional shifting, fear, frustration, low-intensity pleasure, sadness and shyness were significantly higher in the ECC group. Cuddliness, perceptual sensitivity, positive anticipation and soothability were significantly higher in caries-free children. Attentional shifting (p = 0.02), frustration (p = 0.02) and shyness (p = 0.03) were risk factors and cuddliness (p nutritional and oral hygiene habits, easily soothable children were 0.69 times less likely to use sweetened liquids frequently [odds ratio (OR) 0.69, 95% confidence interval (CI) 0.49-0.97, p = 0.03], while sad children were 0.58 times less likely to brush (OR 0.58, 95% CI 0.36-0.94, p = 0.02). Considering temperament traits along with socioeconomic status, positive anticipation was the most significant determinant of ECC (OR 1.57, 95% CI 1.13-2.19, p = 0.007). However, considering temperament, socioeconomic measures and child habits among ECC risk factors, the most significant was the initiation of brushing habits (OR 5.41, 95% CI 2.81-12.98, p = 0.002).

  8. Does breastfeeding increase risk of early childhood caries?

    According to the WHO, "breastfeeding is the normal way of providing young infants with the nutrients they need for healthy growth and development. Exclusive breastfeeding is recommended up to 6 months of age, with continued breastfeeding along with appropriate complementary foods up to two years of age or beyond". However, several studies have reported prolonged and unrestricted breastfeeding as a potential risk factor for primary tooth caries (ECC). On-demand breastfeeding, particularly while lying down at night, would seem to cause ECC because milk remains in the baby's mouth for long periods of time. There is lack of evidence that human milk is cariogenic; other factors, such as oral hygiene, may be more influential in caries development than on-demand breastfeeding. Moreover the biomechanics of breastfeeding differs from those of bottle feeding and milk is expressed into the soft palate and swallowed without remaining on teeth. Indeed we cannot forget that the main factor influencing caries development in infants is the presence of bacteria streptococcus mutans that thrives in a combination of sugars, small amounts of saliva and a low pH. Today the question is open and recently Chaffee, Felines, Vitolo et al. [2014] have found that breastfeeding for 24 months or longer increases the prevalence of severe early childhood caries in low-income families in Porto Alegre, Brazil. These results do not claim that prolonged breastfeeding is the cause of tooth decay; we can expect an association with food for infants often rich in refined sugars, which cause the reduction of the protective effect of saliva on the deciduous teeth enamel. In Japan, Kato, Yorifuji, Yamakawa et al. [2015] have found that infants who had been breastfed for at least 6 or 7 months, both exclusively and partially, were at elevated risk of dental caries at the age of 30 months compared with those who had been exclusively fed with formula. The authors themselves say, however, that further studies

    Early childhood caries (ECC) is a rapid form of dental caries. ECC is the most common chronic childhood disease that can compromise a child's self-esteem, nutritional intake, oral development and quality of life, subsequently leading to malocclusion and psychological problems. The restoration of severely decayed primary teeth is often a difficult procedure that offers a great challenge to paediatric dentists. The present case series document the clinical management of patients suffering from severe early childhood caries using removable partial prosthesis restoring their masticatory function and aesthestics. The ultimate aim of the treatment was to improve psychological and physiological development leading to better functioning of the stomatognathic system. PMID:23843409

    Full Text Available Background: Nitric oxide (NO, a highly reactive radical, participates in the nonspecific natural defense mechanism of the oral cavity. The present study was attempted to evaluate the salivary NO levels in 4–5 year-old children with early childhood caries (ECC. The objective of the present study was to assess the salivary NO concentration in children with different caries activity. Materials and Methods: The study included 120 healthy 4–5 year-old children and they were equally divided into three groups based on decayed, missing, filled surfaces (dmfs score; forty caries-free children (control group, forty children with dmfs 1–5 (ECC group, and forty with dmfs ≥6 (severe ECC group. Saliva collected was measured for NO concentration by Griess reaction method. The obtained data were analyzed by ANOVA and Pearson's correlation coefficient. Results: The mean level of NO in the saliva of the control group was 51.2 ± 8.3457 and that of ECC and severe ECC were 47.1 ± 5.2614 and 33.625 ± 4.6942, respectively. The mean salivary NO concentration was significantly higher in healthy controls when compared to children with ECC and severe ECC. Moreover, a negative correlation (r = −0.6658 was observed between the salivary NO level and the mean dmfs, suggesting that as the salivary NO level decreases, the caries incidence increases. Conclusion: The obtained results support the antimicrobial activity of salivary NO and also suggest that an increase in NO production might contribute to lower the caries occurrence in children.

This cross-sectional study included 329 four-year-old children from São Leopoldo in southern Brazil. Cariogenic dietary practices were assessed at 4 years of age using two 24-hour recalls conducted with the children's mothers. Expenditures on food for children were estimated based on all reported food items and the respective amounts ingested. Early childhood caries and severe early childhood caries were assessed by clinical examination at 4 years of age. Cariogenic dietary habits were not associated with lower food expenditures. On the contrary, in multivariable regression analysis, the intake of chocolate (p = 0.007), soft drinks (p = 0.027) and a higher number of meals and snacks per day (p food for children. No statistically significant differences were observed in food expenditures or in the proportion of household income spent on feeding children between caries-free children, those with early childhood caries and those with severe early childhood caries. In conclusion, keeping children free of dental caries does not necessarily increase food expenditures or the proportion of household income spent on feeding children in low-socioeconomic status populations. Some cariogenic dietary practices were associated with greater expenditures on child feeding.

    Full Text Available Introduction. Early childhood caries (ECC is a special form of caries that affects decideous teeth with rapid progression and numerous complications. Objective. The aim of the study was to define the prevalence of ECC in children of the South Bačka area, the importance of social environment for the prevalence and severity of ECC, and define the model for its prevention. Methods. The survey was the cross-sectional analytical study in the 10% sample of children, aged 13-64 months, different sex, social status and human environment. Severity and prevalence of ECC were assessed by dental check-ups. The epidemiological data were obtained by the interview of parents. The tests of significant statistical differences were performed by the analysis variance and χ2 (p<0.05 test, as well as interdependence of ECC and single characteristics that could be a predictor of the disease by the logistic regression. Results. The prevalence of ECC was 30.5%. The highest disease frequency was found in children of male sex (35.1%, out of kindergardens (54.2%, in the third and the next born child in the family (46.9% and in part-time employed mothers (47.2% who had only elementary education (59.3% and were poorly informed about oral health. The highest prevalence (47.1% of ECC was found in children whose parents had the lowest income per month. Type 1 of ECC was the most presented one (75.0%. Conclusion. The higher prevalence and more severe ECC were found in the third and the next born male child from rural environment.

    Full Text Available Background and objective: Bacterial invasion into pulps of primary teeth can lead to infection and premature tooth loss in children. This pilot study aimed to explore whether the microbiota of carious exposures of dental pulps resembles that of carious dentin or that of infected root canals. Design: Children with severe early childhood caries were studied. Children were consented and extent of caries, plaque, and gingivitis measured. Bacteria were sampled from carious lesion biofilms and vital carious exposures of pulps, and processed by anaerobic culture. Isolates were characterized from partial sequences of the 16S rRNA gene and identified by comparison with taxa in the Human Oral Microbiome Database (http://www.HOMD.org. The microbiotas of carious lesions and dental pulps were compared using univariate and multivariate approaches. Results: The microbiota of cariously exposed pulps was similar in composition to that of carious lesion biofilms except that fewer species/taxa were identified from pulps. The major taxa identified belonged to the phyla Firmicutes (mainly streptococci and Actinobacteria (mainly Actinomyces species. Actinomyces and Selenomonas species were associated with carious lesions whereas Veillonella species, particularly Veillonella dispar was associated with pulps. Other bacteria detected in pulps included Streptococcus mutans, Parascardovia denticolens, Bifidobacterium longum, and several Lactobacillus and Actinomyces species. By principal, component analysis pulp microbiotas grouped together, whereas those in caries biofilms were widely dispersed. Conclusions: We conclude that the microbiota of cariously exposed vital primary pulps is composed of a subset of species associated with carious lesions. Vital primary pulps had a dominant Firmicutes and Actinobacteria microbiota which contrasts with reports of endodontic infections which can harbor a gram-negative microbiota. The microbiota of exposed primary pulps may provide

    Full Text Available Abstract Background Dental caries (decay is an international public health challenge, especially amongst young children. Early Childhood Caries is a rapidly progressing disease leading to severe pain, anxiety, sepsis and sleep loss, and is a major health problem particularly for disadvantaged populations. There is currently a lack of research exploring the interactions between risk and protective factors in the development of early childhood caries, in particular the effects of infant feeding practises. Methods/Design This is an observational cohort study and involves the recruitment of a birth cohort from disadvantaged communities in South Western Sydney. Mothers will be invited to join the study soon after the birth of their child at the time of the first home visit by Child and Family Health Nurses. Data on feeding practices and dental health behaviours will be gathered utilizing a telephone interview at 4, 8 and 12 months, and thereafter at 6 monthly intervals until the child is aged 5 years. Information collected will include a initiation and duration of breastfeeding, b introduction of solid food, c intake of cariogenic and non-cariogenic foods, d fluoride exposure, and e oral hygiene practices. Children will have a dental and anthropometric examination at 2 and 5 years of age and the main outcome measures will be oral health quality of life, caries prevalence and caries incidence. Discussion This study will provide evidence of the association of early childhood feeding practices and the oral health of preschool children. In addition, information will be collected on breastfeeding practices and the oral health concerns of mothers living in disadvantaged areas in South Western Sydney.

    Full Text Available Background: Early Childhood Caries (ECC in the earliest stage is preventable. The studies indicate oral bacteria play an important role in pathogenesis of dental caries. According to high prevalence of ECC, alternative therapies should be explored in order to reduce the occurrence of it. Aim: This study aims to assess the effectiveness of a product containing Povidone Iodine 10% and Sodium Fluoride 0.2% as a supplementary intervention for preventing ECC.Materials and Methods: Thirty-seven children aged 4 to 6 year-old were recruited. Maxillary incisors on each side of the mouth were selected either as a test or control group. Early caries detection examinations were conducted using International Caries Detection and Assessment System (ICDAS clinically and photographically. In a double-blind, placebo-controlled clinical study, a product containing a mixture of  Povidone Iodine 10%  and Sodium Fluoride 0.2%  was applied to the designated incisors of the test group participants. This application was performed every week for a 3-month. The control group participants received a placebo mixture during the same time interval. The caries detection examinations were conducted again after 6 months and the results were compared. The data was analyzed with SPSS V.18, using McNemar test.Results: The incidence of carious lesions increased for the control group while it decreased in the test group (P

    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.

    Full Text Available Background: Lifestyle diseases including dental caries are partly preventable, and associated with health behavior. Establishing favorable health behavior is one main challenge both in general and dental health services. The purpose of this paper was to focus on cross-disciplinary research that has the potential to prevent development of both dental caries and other lifestyle diseases. More specifically the aim was to study how family characteristics and health behavior in pregnancy and early childhood influence caries development in preschool children.Material and methods: Data from dental examination of 5 year old children in the public dental services was linked to data from MoBa. In total, 1348 children were followed from pregnancy to 5 years of age. The data has provided opportunity to follow longitudinally the development of oral health behavior in early childhood in a large sample, and to study associations between caries development during preschool age and information in the MoBa database.Results: Results from the studies showed that tooth brushing frequency established at 1.5 year of age was stable through preschool age. Caries development in preschool age was related to child and maternal risk behavior in early childhood and to characteristics of risk families.Conclusion: Cross-disciplinary research using MoBa data has given new knowledge on dental caries development in early childhood in Norway. This knowledge can be used in clinical practice both in general and dental health services to improve preventive efforts towards early childhood caries and other lifestyle diseases.

    Microbiota-based prediction of chronic infections is promising yet not well established. Early childhood caries (ECC) is the most common infection in children. Here we simultaneously tracked microbiota development at plaque and saliva in 50 4-year-old preschoolers for 2 years; children either stayed healthy, transitioned into cariogenesis, or experienced caries exacerbation. Caries onset delayed microbiota development, which is otherwise correlated with aging in healthy children. Both plaque and saliva microbiota are more correlated with changes in ECC severity (dmfs) during onset than progression. By distinguishing between aging- and disease-associated taxa and exploiting the distinct microbiota dynamics between onset and progression, we developed a model, Microbial Indicators of Caries, to diagnose ECC from healthy samples with 70% accuracy and predict, with 81% accuracy, future ECC onsets for samples clinically perceived as healthy. Thus, caries onset in apparently healthy teeth can be predicted using microbiota, when appropriately de-trended for age. PMID:26355216

    Introduction Candida albicans has been detected together with Streptococcus mutans in high numbers in plaque-biofilm from children with early childhood caries (ECC). The goal of this study was to examine the C. albicans carriage in children with severe early childhood caries (S-ECC) and the maternal relatedness. Methods Subjects in this pilot cross-sectional study were recruited based on a convenient sample. DMFT(S)/dmft(s) caries and plaque scores were assessed during a comprehensive oral exam. Social-demographic and related background information was collected through a questionnaire. Saliva and plaque sample from all children and mother subjects were collected. C. albicans were isolated by BBL™ CHROMagar™ and also identified using germ tube test. S. mutans was isolated using Mitis Salivarius with Bacitracin selective medium and identified by colony morphology. Genetic relatedness was examined using restriction endonuclease analysis of the C. albicans genome using BssHII (REAG-B). Multilocus sequence typing was used to examine the clustering information of isolated C. albicans. Spot assay was performed to examine the C. albicans Caspofungin susceptibility between S-ECC children and their mothers. All statistical analyses (power analysis for sample size, Spearman’s correlation coefficient and multiple regression analyses) were implemented with SAS 9.4 Results A total of 18 S-ECC child-mother pairs and 17 caries free child-mother pairs were enrolled in the study. Results indicated high C. albicans carriage rate in the oral cavity (saliva and plaque) of both S-ECC children and their mothers (>80%). Spearman’s correlation coefficient also indicated a significant correlation between salivary and plaque C. albicans and S. mutans carriage (pcaries severity (pcaries-free children). Among 18 child-mother pairs, >60% of them demonstrated identical C. albicans REAG-B pattern. C. albicans isolated from >65% of child-mother pairs demonstrated similar susceptibility to

    Full Text Available Abstract Background Even though it has been widely studied, early childhood caries (ECC remains a serious public health problem, especially in countries where there is no national program of oral health assessment and no genuine primary oral health care, such as in Kosovo. The purpose of this study was to assess the prevalence of ECC and analyze caries risk factors. Methods The subjects were 1,008 preschool children, selected by stratified random cluster sampling, in the municipality of Prishtina, capital of Kosovo. Data were collected through clinical examination and interviews. Dmft data were recorded according to WHO criteria. Bacterial examination (CRT bacteria test and plaque test of Greene-Vermillion were used. Results The mean dmft of preschool children was found to be 5.8. The prevalence of ECC was 17.36%, with a mean dmft of 11 ± 3.6. Streptococcus mutans prevalence in ECC children was 98%. A significant correlation between dmft and S mutans counts (≥105 CFU/mL saliva was demonstrated. A correlation was also found between daily sweets consumption and dmft in children with ECC (P P Conclusion The prevalence of ECC was high among preschool children in the municipality of Kosovo. We recommend increasing parents' knowledge of proper feeding habits and oral health practices, and increasing preschool children's accessibility to dental services.

    Full Text Available Background: Severe early childhood caries (S-ECC and decay exfoliation filling teeth (def-t >6 is a destructive disease that afflicts teeth, including maxillary anterior teeth. In Indonesia, the prevalence of this disease is still high, for instance in Semarang 2007, the rate reached 90.5% in urban areas and 95.9% in rural areas for early childhood caries which is caused by Streptococcus mutans (S. mutans. Neutrophils are effector cells of innate immunity which become the main component of the very first line of defense against microbes. Purpose: This study analyzed the effect caused by the change of CD63 expression on the surface of salivary neutrophils and the increased level of S. mutans in S-ECC. Method: This study employs observational analytic and cross sectional approach by using T test analysis technique for forty cases of early childhood that had been divided into two groups, first group of twenty children positively diagnosed as S-ECC and second group of twenty children negatively diagnosed as the control group. The sample’s result of gargling with 1.5% NaCl was used for neutrophils isolation and analysis function of salivary neutrophils phagocytosis by using flow cytometry test, while the sample of saliva was used to isolate S. mutans and calculate the level of S. mutans. Result: The expression of CD63+ salivary neutrophils in S-ECC was lower (2.32% ± 0.57 than in caries-free (2.67% ± 0.46, while the level of S. mutans showed that the level was not higher than in S-ECC (9.78 ± 2.22x105 CFU/ml compared to in caries-free (5.13 ± 1.86x105 CFU/ml. Conclusion: The low expression of CD63 in salivary neutrophils can lead to the increased level of S. mutans in S-ECC.

    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.

    Full Text Available Statement of the Problem: Early childhood caries is an important oral health issue. Finding its prevalence would predict the need for oral health promotion disciplines for specific age groups. Purpose: The aim of this study was to assess the caries experience of children living in Tehran, Iran. It also would evaluate the impact of gender, ethnicity, and socioeconomic status (SES on this oral condition. Materials and Method: This epidemiological cross-sectional study was based upon stratified cluster random sampling. The samples consisted of 239 children (2- to 3- years old registered in Tehran’s public healthcare centers for “Healthy Child Program”. Mothers of the recruited children were interviewed for the background data; then children were examined for the oral health status according to ICDAS-II (International Caries Detection and Assessment System and WHO (World Health Organization criteria. Statistical analyses were conducted using STATA.11 for SES classification considering six socioeconomic variables, and SPSS.21 for descriptive/analytical analyses. Results: Primary Component Analysis (PCA demonstrated five classes of SES ranging from the lowest to the highest. The distribution of caries-free (CF children was 10.87%, non-cavitated enamel caries (codes 01-02 were 28.03%, and about 61.1% had cavitated caries (codes 03-06. There was no significant difference in caries experience between the two genders. Cavitated lesions were more prevalent among Kurdish, who also had the least CF children. Caries prevalence, especially code 02, was more among children from 3rd class SES (moderate level. Gender, ethnicity, or SES had no impact on the CF status of the children; however, ethnicity showed significant impact on the prevalence of extensive caries (codes 05-06. Conclusion: The result of the present study is indicative of high caries prevalence among 2 to 3 years old children residing in Tehran. It highlights the need for comprehensive oral

    Full Text Available Abstract Background Severe tooth decay is known to affect the health and well-being of young children. However, little is known about the influence of Severe Early Childhood Caries (S-ECC on childhood nutritional status. The purpose of this study was to contrast ferritin and haemoglobin levels between preschoolers with S-ECC and caries-free controls. Methods Children were recruited as part of a larger case–control study examining differences in nutritional status between those with and without S-ECC. Preschoolers with S-ECC were recruited on the day of their dental surgery, while caries-free controls were recruited from the community. Parents completed a questionnaire and the child underwent venipuncture. The study was approved by the University’s Health Research Ethics Board. Statistics included descriptive, bivariate and logistic regression analyses. A p value ≤ .05 was significant. A total of 266 children were recruited; 144 with S-ECC and 122 caries-free. Results The mean age was 40.8 ± 14.1 months. The mean ferritin concentration for all children was 29.6 ± 17.9 μg/L while the mean haemoglobin level was 115.1 ± 10.1 g/L. Children with S-ECC were significantly more likely to have low ferritin (p=.033 and low haemoglobin levels (p>.001. Logistic regression analyses revealed that children with S-ECC were nearly twice as likely to have low ferritin levels and were over six times more likely to have iron deficiency anaemia than caries-free controls. Conclusions Children with S-ECC appear to be at significantly greater odds of having low ferritin status compared with caries-free children and also appear to have significantly lower haemoglobin levels than the caries-free control group. Children with S-ECC also appear to be at significantly greater odds for iron deficiency anaemia than cavity-free children.

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

Caries occurred at a relatively constant rate over the period of study, but in all sugar consumption groups, the increment of dental caries was slightly higher between ages 6 and 12 y than between 12 and 18 y. Adjusted analysis showed that dental caries increment ratio between ages 6 and 18 y was 20% and 66% higher in upward and high sugar consumer groups as compared with low consumers. The higher the sugar consumption along the life course, the higher the dental caries increment. Even the low level of sugar consumption was related to dental caries, despite the use of fluoride.

    The mainstay of pediatric dental practice is the successful esthetic rehabilitation of a preschooler with advanced carious lesions. Loss of masticatory efficiency, compromised esthesis, mispronunciation of labiodentals sounds, and development of abnormal oral habits are compromises arising due to the loss of primary anterior teeth at an early age either due to trauma or due to caries. Parental desire is the most decisive factor for the placement of an anterior esthetic appliance. This unique case report highlights the fabrication of simple, Groper's appliance in a 5-year-old child with early childhood caries. PMID:26538948

    Full Text Available The prevalence and severity of caries in children under three years old are constantly increasing. One of the cause is the increase consumption of cariogenic carbohydrate. Breast milk have buffer capacity that eventually able to prevent caries. The aims of this research are to discover the correlation between breastfeeding with the severity of Early Childhood Caries (ECC in children under three years old, to provide information on prevalence and severity of caries in children under three years, and to explain factors influencing the incidence of ECC. This research designed cross sectionally and conducted upon 565 children aged 12-38 months, selected using multistage cluster random sampling. The ECC prevalence of children under three years in DKI Jakarta is 52.7%, with average score of def-t 2.85. Bivariate analysis showed that, variables which correlate with the level of ECC are; the way to deliver (p=0,012, frequency (p=0,002, duration (p=0,002, salivary buffer capacity (p=0.013, habitual consumption of sugary diet (p=0.005, child’s dental hygiene behavior (p=0.002, and mother’s education (p=0.001. Multivariate analysis showed that ECC can be explained by these variables: age, mother’s education, the way to deliver and frequency of breast milk complements/replacement of consumtions, child’s brushing habit, plaque pH, and salivary buffer capacity. Resulting determination coefficient 32.1%. There is no significant correlation between breastfeeding and the level of Early Childhood Caries (ECC. The role of protective qualities of breastfeeding are not shown because of bias in obtaining data influence the incidence of caries.

    It is widely acknowledged that parental beliefs (self-efficacy) about oral health and parental oral health-related behaviours play a fundamental role in the establishment of preventative behaviours that will mitigate against the development of childhood dental caries. However, little attention has been given to the wider perspective of family functioning and family relationships on child oral health. For oral health researchers, exploration of this association requires the use of reliable, valid and appropriate assessment tools to measure family relationships. In order to promote methodologically sound research in oral health, this systematic review aims to provide a guide on self-report psychometric measures of family functioning that may be suitable to utilize when exploring childhood dental caries. This systematic review has identified 29 self-report measures of family functioning and evaluated them in terms of their psychometric support, constructs measured and potential utility for oral health research. The majority of the measures reported adequate levels of reliability and construct validity. Construct evaluation of the measures identified five core domains of family functioning, namely 'communication', 'cohesion/engagement', 'control', 'involvement' and 'authoritative/rigid parenting style'. The constructs were subsequently evaluated with respect to their potential relevance to child oral health. Herewith this review provides a framework to guide future research to explore family functioning in furthering our understanding of the development of childhood dental caries. PMID:24107605

    Full Text Available Background: The prevalence of severe early childhood caries (sECC is high in developing nations like India. It has local as well as systemic manifestations. Aims: This study evaluated the influence of sECC and its management on growth parameters and quality of life (QoL of preschool children from low socioeconomic status families. Materials and Methods: 100 preschool children (50 with sECC and 50 with no dental caries; mean age 5.42 ± 0.74 years from low socioeconomic status were studied. QoL; Decayed, extracted and filled teeth (def index; Height (Ht; Weight (Wt; Head circumference (HC; Mid arm circumference (MAC; and, Body Mass Index (BMI were recorded at baseline and compared after six months of dental rehabilitation. The test group included children with sECC having def > 6 and at least one pulpally involved tooth.The control group children did not have DC (def =0. Both the groups were age, gender and socioeconomic status matched. Statistical Analysis: Statistical analysis was done using Statistical Package for the Social Sciences (SPSS v.11.0 computer software. Chi-square test, Analysis of Variance (ANOVA, Fisher′s exact and paired t tests were performed for comparing the groups at baseline and six month recall visit. Results: Baseline measurements showed that 46% of children with sECC had Wt below 3rd percentile (underweight; mean 15.49 ± 1.87Kg which was less than the controls (mean Wt 16.34 ± 1.46kg. They also complained of pain (40%, avoidance of hard food (24%, noticed Wt loss (18% and sleep disturbances (12%. After 6 months of dental rehabilitation, there was a significant improvement in their Wt (P= 0.002 and QoL. Conclusions: sECC negatively influenced the Wt and QoL of children. Awareness, education of parents and facilitation of oral health services may help in improving their Wt and QoL.

    The aim of this case-control study was to explore the relationship between parenting practices, parent-child interaction and childhood dental caries, using a sample of 5-8-year old children from the Netherlands. Cases were defined as children with four or more decayed, missing or filled teeth and controls were caries free. Cases (n = 28) and controls (n = 26) were recruited from a referral centre for paediatric dental care and a general dental practice, respectively. Parenting practices and parent-child interactions of the child's primary caregiver were observed using Structured Interaction Tasks and subsequently rated on seven dimensions: positive involvement, encouragement, problem-solving, discipline, monitoring, coercion and interpersonal atmosphere. All Structured Interaction Tasks were videotaped, and coded by trained and calibrated observers blind to the dental condition. Differences in parenting dimensions between cases and controls were analysed using multivariate analysis of variance, independent samples T-tests, χ(2)-tests and multiple logistic regression analyses. Controls had significantly higher scores on the dimensions positive involvement, encouragement, problem-solving and interpersonal atmosphere, compared to cases. Parents of controls were also less likely to show coercive behaviours. These associations remained statistically significant after adjustment for the mother's education level, tooth brushing frequency and the frequency of consuming sugary foods and drinks, except for coercion. There was no significant difference in discipline between cases and controls. In conclusion, this case-control study found a significant relationship between parenting practices, parent-child interaction quality and childhood dental caries. Our findings suggest that parenting practices may be an important factor to consider in caries preventive programs. PMID:24980791

    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. PCPs played an important role in preventing early childhood caries among preschool children with CHD in Guangzhou, China.

    Full Text Available The relationship between early childhood caries (ECC and obesity is controversial. This cross-sectional survey investigated this association in children from low-income families in Goiania, Goias, Brazil and considered the role of several social determinants. A questionnaire examining the characteristics of the children and their families was administered to the primary caregiver during home visits. In addition, children (approximately 6 years of age had their height, weight, and tooth condition assessed. The primary ECC outcome was categorized as one of the following: caries experience (decayed, missing, filled tooth: “dmft” index > 0, active ECC (decayed teeth > 0, or active severe ECC (decayed teeth ≥ 6. Descriptive, bivariate and logistic regression analyses were conducted. The participants in the current study consisted of 269 caregiver-child dyads, 88.5% of whom were included in the Family Health Program. Caregivers were mostly mothers (67.7%, were 35.3 ± 10.0 years old on average and had 9.8 ± 3.1 years of formal education. The mean family income was 2.3 ± 1.5 times greater than the Brazilian minimum wage. On average, the children in the current study were 68.7 ± 3.8 months old. Of these, 51.7% were boys, 23.4% were overweight or obese, 45.0% had active ECC, and 17.1% had severe ECC. The average body mass index (BMI of the children was 15.9 ± 2.2, and their dmft index was 2.5 ± 3.2. BMI was not associated with any of the three categories of dental caries (p > 0.05. In contrast, higher family incomes were significantly associated with the lack of caries experience in children (OR 1.22, 95%CI 1.01–1.50, but the mother’s level of education was not significantly associated with ECC.

    Full Text Available The habit of nocturnal bottle or breast-feeding has been reported to be a potential cause for early childhood caries (ECC in very young children. The aim of this study was to determine the prevalence of ECC in children 2-5 years of age attending out patient clinic HUSM, in relation to the nursing habits. In this cross-sectional study, 90 children were randomly selected to examine their caries status using torch and disposable mirror. Data on mothers’ educational level, nursing habits and oral hygiene practices, were gather by using structured questionnaire. It has been found that 16.7% of subjects were caries free while 83.3% of them had caries with mean dmf score 6 (SD 5.3. With regard to nursing habits, 29% of subjects had breast-feeding alone, 16% had bottle-feeding alone and 55% had both breast and bottle-feeding. Ninety-three percent of children had been nursed beyond 14 months and 47% had been fed with liquids other than breast milk, infant formula or water. Twenty-seven percent of children were allowed to sleep with nursing bottle in mouth and 52% were allowed to sleep with breast nipple in the mouth which shows significantly associated with ECC (p = 0.03. Tooth brushing habit was reported for 91% of children using toothpaste. Mean age of the children (in months when the mothers started brushing the teeth was 19.1 (SD 10.8 and has significant association with ECC (p < 0.05. This study demonstrates that the habit of allowing infants to sleep with breast nipple in their mouth and the late start of tooth brushing are associated with prevalence of ECC. Educational programs for pregnant women and mothers of young children should be emphasized to enhance the knowledge and awareness of mothers in preventing ECC.

    The current rise in childhood caries worldwide has increased the demand for portable technologies that can quickly and accurately detect and diagnose early stage carious lesions. These lesions, if identified at an early stage, can be reversed with remineralization treatments, education, and improvements in home care. A multi-modal optical prototype for detecting and diagnosing occlusal caries demineralization in vivo has been developed and pilot tested. The device uses a 405-nm laser as a scanned illumination source to obtain high resolution and high surface contrast reflectance images, which allows the user to quickly image and screen for any signs of demineralized enamel. When a suspicious region is located, the device can be switched to perform dual laser fluorescence spectroscopy using 405-nm and 532-nm laser excitations. These spectra are used to compute an auto-fluorescence (AF) ratio of the suspicious region and the percent difference of AF ratios from a healthy region of the same tooth. The device was tested on 7 children's teeth in vivo with clinically diagnosed carious lesions. Lesion depth was then visually estimated from the video image using the 405-nm scanned light source, and within a month the maximum drill depth was assessed by a clinician. The researcher and clinicians were masked from previous measurements in a blinded study protocol. Preliminary results show that the ratiometric percent difference measurement of the AF spectrum of the tooth correlates with the severity of the demineralization as assessed by the clinician after drilling.

    The incidence of early childhood caries (ECC) is a global public health concern. The oral health knowledge of a caregiver can affect a child's risk for developing ECC. An exploratory study of the oral health knowledge and behaviors among caregivers of children 6 years of age and younger was conducted with a convenience sample of adults (n = 114) enrolled in English language or high school equivalency examination courses. The majority of study participants were born in Asia (47 %). Other birth regions included South America (16 %), Caribbean (16 %), Africa (10 %), and Central America (6 %). Study findings showed caregivers with low oral health knowledge were more likely to engage in behaviors that increase a child's risk for developing ECC. A statistically significant relationship was found between participants' rating of their child's dental health as poor and the belief that children should not be weaned from the nursing bottle by 12 months of age (P = 0.002), brushing should not begin upon tooth eruption (P = 0.01), and fluoride does not strengthen teeth and prevent dental caries (P = 0.005). Subjects who pre-chewed their child's food also exhibited behaviors including sharing eating utensils or a toothbrush with their child (P < 0.001). Additional caregiver behaviors included providing their child with a bottle containing cariogenic liquids in a crib (P < 0.001). As a result of this research, it is pertinent that culturally sensitive oral health promotion programs are developed and implemented to raise awareness and reduce the risk of dental disease among immigrant populations.

    Full Text Available Candida albicans is strongly associated with severe early childhood caries (S-ECC. However, the roles of secreted aspartyl proteinases (Saps, an important virulence factor of C. albicans, in the progress of S-ECC are not clear. In our study, the Saps activities were evaluated by the yeast nitrogen base–bovine serum albumi (YNB–BSA agar plate method and by the MTT method with bovine serum albumin (BSA as the substrate. Genotypes of C. albicans and gene expression of Sap1–5 were evaluated. The relationships of Saps activities and genotypes with S-ECC were analyzed. The results showed that enzyme activities of Saps in the S-ECC group were significantly higher than those in the caries free (CF group (p < 0.05. Genotypes A, B and C were detected in the S-ECC group, and genotypes A and C were detected in the CF group. In the genotype A group, Saps activity in the S-ECC group was significantly different from that in the CF group (p < 0.05. The gene expression level of Sap1 in the S-ECC group was significantly higher than that in the CF group (p = 0.001, while Sap4 expression was significantly lower than that in the CF group (p = 0.029. It can be concluded that Sap1–5 are the predominant proteinase genes expressed in C. albicans from dental biofilm and Sap1 may play an important role in the development of S-ECC.

    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.

    Background Although several studies have shown short term health benefits of exclusive breastfeeding (EBF), its long term consequences have not been studied extensively in low-income contexts. This study assessed the impact of an EBF promotion initiative for 6 months on early childhood caries (ECC) and breastfeeding duration in children aged 5 years in Mbale, Eastern Uganda. Methods Participants were recruited from the Ugandan site of the PROMISE- EBF cluster randomised trial (ClinicalTrials.gov no: NCT00397150). A total of 765 pregnant women from 24 clusters were included in the ratio 1:1 to receive peer counselled promotion of EBF as the intervention or standard of care. At the 5 year follow-up, ECC was recorded under field conditions using the World Health Organization’s decayed missing filled tooth (dmft) index. Adjusted negative binomial and linear regression were used in the analysis. Results Mean breastfeeding duration in the intervention and control groups (n=417) were 21.8 (CI 20.7–22.9) and 21.3(CI 20.7–21.9) months, respectively. The mean dmft was 1.5 (standard deviation [SD] 2.9) and 1.7 (SD 2.9) in the intervention and control groups, respectively. Corresponding prevalence estimates of ECC were 38% and 41%. Negative binomial regression analysis adjusted for cluster effects and loss-to-follow-up by inverse probability weights (IPW) showed an incidence-rate ratio (IRR) of 0.91 (95% CI 0.65–1.2). Comparing the effect of the trial arm on breastfeeding duration showed a difference in months of 0.48 (-0.72 to 1.7). Conclusion PROMISE EBF trial did not impact on early childhood caries or breastfeeding duration at 5 years of age. This study contributes to the body of evidence that promotion of exclusive breastfeeding does not raise oral health concerns. However, the high burden of caries calls for efforts to improve the oral health condition in this setting. Trial Registration ClinicalTrials.gov NCT00397150 PMID:25938681

    Full Text Available While the impact of therapeutic levels of ionizing radiation during childhood on dental defects has been documented, the possible effect of low doses on dental health is unknown. The study aims were to assess the association between childhood exposure to low-moderate doses of therapeutic radiation and caries experience among a cohort of adults 50 years following the exposure.The analysis was based on a sample of 253 irradiated (in the treatment of Tinea Capitis and 162 non-irradiated subjects. The DMFT (Decayed, Missing, and Filled Teeth index was assessed during a clinical dental examination and questions regarding dental care services utilization, oral hygiene behavior, current self-perceived mouth dryness, socio-demographic parameters and health behavior variables were obtained through a face to face interview.An ordered multivariate logistic regression model was used to assess the association of the main independent variable (irradiation status and other relevant independent variables on the increase in DMFT.Mean caries experience levels (DMFT were 18.6+7.5 for irradiated subjects compared to 16.4+7.2 for the non-irradiated (p=0.002. Controlling for gender, age, education, income, smoking, dental visit in the last year and brushing teeth behavior, irradiation was associated with a 72% increased risk for higher DMFT level (95% CI 1.19-2.50. A quantification of the risk by dose absorbed in the salivary gland and in the thyroid gland showed adjusted ORs of 2.21 per 1Gy (95% CI 1.40-3.50 and 1.05 per 1cGy (95% CI 1.01-1.09, respectively.Childhood exposure to ionizing radiation (0.2-0.4Gy might be associated with late outcomes of dental health. In line with the guidelines of the American Dental Association, these results call for caution when using dental radiographs.

    Early childhood caries (ECC) is closely related to high numbers of mutans streptococci, lactobacilli and Candida albicans. Oral colonization of these microorganisms was monitored in a prospective clinical study in order to investigate the effect of comprehensive treatment under general anesthesia and the sustainability of microbial changes. Saliva samples were collected from 50 healthy infants with ECC before and in regular intervals up to 12 months after treatment. Microorganisms were detected by cultivation on selective agars (CRT® bacteria and Sabouraud/CandiSelect™) and scored. Additionally, plaque on upper front teeth and the dmft were recorded. Parents were repeatedly interviewed regarding the children's diet and oral hygiene, accompanied by corresponding advice. Plaque frequency and the numbers of mutans streptococci, lactobacilli and yeasts were significantly reduced as a result of treatment (p caries relapse (p Nutritional and oral hygiene habits changed only slightly despite advising. Elimination and restoration of ECC lesions under general anesthesia proved to be an effective procedure in reducing cariogenic bacteria and yeasts. A satisfactory and sustainable success, however, could be achieved neither regarding microbiologic parameters nor with respect to the relapse rate. More suitable strategies are needed. PMID:24216710

    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.

    Dental caries is a multifactorial disease, in which saliva has an important role. Saliva properties affect the growth of cariogenic microorganisms, so variations below threshold levels are considered risk factors for the development of dental caries. Salivary tests and microbiological counts of cariogenic bacteria are often used for clinical purposes in order to reveal problems that could explain caries development and have been evaluated in multiple studies, but these studies have mainly been carried out on adults. Thus, the aim of this study was to identify physicochemical salivary properties, mutans streptococci and Lactobacillus counts among preschool children, and their relationship with ECC in a cross-sectional study in Medellín, Colombia. Caries was determined using ICDAS criteria for a sample of 201 preschool children. Stimulated saliva samples were processed for bacterial detection, mean flow rate, pH and buffer capacity calculation. Risk variables for ECC were assessed individually and adjusted using a binary logistic regression model. The results showed that 71.14% of study subjects had ECC. Flow rate, final pH and Buffer capacity increased with age, but none of them were related to the presence of ECC. Although OR analysis detected correlations between ECC, gender age, dental eruption stage and Lactobacillus presence, binary logistic regression analysis only showed gender and Lactobacillus as strongly associated with ECC. It can be concluded that gender and Lactobacillus presence are key variables for the presence of ECC in these children; whilst age and dental eruption stage play a minor role. Further studies are required to clarify the role of mutans streptococci counts in this population and to establish normal salivary parameters as well as threshold levels for hyprosalivation in preschool children, as results showed differences with normal parameters used for adults.

    While the impact of therapeutic levels of ionizing radiation during childhood on dental defects has been documented, the possible effect of low doses on dental health is unknown. The study aim was to assess the association between childhood exposure to low–moderate doses of therapeutic radiation and caries experience among a cohort of adults 50 years following the exposure. The analysis was based on a sample of 253 irradiated (in the treatment of tinea capitis) and 162 non-irradiated subjects. The decayed, missing, and filled teeth (DMFT) index was assessed during a clinical dental examination and questions regarding dental care services utilization, oral hygiene behavior, current self-perceived mouth dryness, socio-demographic parameters, and health behavior variables were obtained through a face-to-face interview. An ordered multivariate logistic regression model was used to assess the association of the main independent variable (irradiation status) and other relevant independent variables on the increase in DMFT. Mean caries experience levels (DMFT) were 18.6 ± 7.5 for irradiated subjects compared to 16.4 ± 7.2 for the non-irradiated (p = 0.002). Controlling for gender, age, education, income, smoking, dental visit in the last year, and brushing teeth behavior, irradiation was associated with a 72% increased risk for higher DMFT level (95% CI: 1.19–2.50). A quantification of the risk by dose absorbed in the salivary gland and in the thyroid gland showed adjusted ORs of 2.21 per 1 Gy (95% CI: 1.40–3.50) and 1.05 per 1 cGy (95% CI: 1.01–1.09), respectively. Childhood exposure to ionizing radiation (0.2–0.4 Gy) might be associated with late outcomes of dental health. In line with the guidelines of the American Dental Association, these results call for caution when using dental radiographs. PMID:26942172

    Background. Early childhood caries (ECC) is associated with early colonisation and high levels of cariogenic microorganisms. With C. albicans being one of those, there is a need to determine the effectiveness of various chemotherapeutic agents against it. The study is aimed at isolating Candida species in children with ECC and at studying the antifungal effect of coconut oil, probiotics, Lactobacillus, and 0.2% chlorhexidine on C. albicans in comparison with ketoconazole. Materials and Methods. Samples were collected using sterile cotton swabs, swabbed on the tooth surfaces from children with ECC of 3 to 6 yrs and streaked on Sabouraud dextrose agar (HI Media) plates and incubated in a 5% CO2 enriched atmosphere at 37°C for 24 hours. Candida was isolated and its susceptibility to probiotics, chlorhexidine, ketoconazole, and coconut oil was determined using Disc Diffusion method. Results. The mean zone of inhibition for chlorhexidine was 21.8 mm, whereas for coconut oil it was 16.8 mm, for probiotics it was 13.5 mm, and for ketoconazole it was 22.3 mm. The difference between the groups was not statistically significant (Chi-square value 7.42, P value 0.06). Conclusion. Chlorhexidine and coconut oil have shown significant antifungal activity which is comparable with ketoconazole.

    High doses of ionizing radiation are an established cause of childhood leukemia. However, substantial uncertainty remains about the effect of low doses of radiation, including background radiation and potential differences between genetic subgroups of leukemia have rarely been explored. We investigated the effect of the background gamma radiation on childhood leukemia using a nationwide register-based case-control study. For each of the 1,093 cases, three age- and gender matched controls were selected (N = 3,279). Conditional logistic regression analyses were adjusted for confounding by Down syndrome, birth weight (large for gestational age), and maternal smoking. Complete residential histories and previously collected survey data of the background gamma radiation in Finland were used to assess the exposure of the study subjects to indoor and outdoor gamma radiation. Overall, background gamma radiation showed a non-significant association with the OR of childhood leukemia (OR 1.01, 95% CI 0.97, 1.05 for 10 nSv/h increase in average equivalent dose rate to red bone marrow). In subgroup analyses, age group 2-childhood leukemia, particularly at age 2-<7 years. Our findings suggest a larger effect of radiation on leukemia with high hyperpdiploidy than other subgroups, but this result requires further confirmation. PMID:27405274

    Full Text Available Abstract Background Diagnosing childhood asthma is dependent upon parental symptom reporting but there are problems in the use of words and terms. The purpose of this study was to describe and compare understandings of childhood 'asthma' by mothers from three different ethnic backgrounds who have no personal experience of diagnosing asthma. A better understanding of parents' perceptions of an illness by clinicians should improve communication and management of the illness. Method Sixty-six mothers living in east London describing their ethnic backgrounds as Bangladeshi, white English and black Caribbean were recruited to 9 focus groups. Discussion was semi-structured. Three sessions were conducted with each ethnic group. Mothers were shown a video clip of a boy with audible wheeze and cough and then addressed 6 questions. Sessions were recorded and transcribed verbatim. Responses were compared within and between ethnic groups. Results Each session, and ethnic group overall, developed a particular orientation to the discussion. Some mothers described the problem using single signs, while others imitated the sound or made comparisons to other illnesses. Hereditary factors were recognised by some, although all groups were concerned with environmental triggers. Responses about what to do included 'normal illness' strategies, use of health services and calls for complementary treatment. All groups were concerned about using medication every day. Expectations about the quality of life were varied, with recognition that restrictions may be based on parental beliefs about asthma, rather than asthma itself. Conclusion Information from these focus groups suggests mothers know a great deal about childhood asthma even though they have no personal experience of it. Knowledge of how mothers from these ethnic backgrounds perceive asthma may facilitate doctor – patient communication with parents of children experiencing breathing difficulties.

    Full Text Available Objectives. The high prevalence and severity of caries among Canadian First Nations children is a growing concern. Dental surgery in hospital is often necessary to treat the signs of decay but does not address the underlying factors contributing to its development. The purpose of this study was to determine the prevalence and risk factors of caregiver-reported Baby Bottle Tooth Decay (BBTD, or Severe Early Childhood Caries (S-ECC, among preschool children recruited in Phase 2 of the First Nations Regional Longitudinal Health Survey (RHS. Study Design. Cross-sectional study including interviews with caregivers. Methods. This study was limited to data from Manitoba First Nations participating in the RHS Phase 2 (2008–10. Data were restricted to caregiver interviews for their child <72 months of age. The main variable of interest was caregiver-reported BBTD, an antecedent term for S-ECC. Data analysis included descriptive statistics and bivariate analyses; p≤0.05 was significant. Results. Overall, caregivers of 431 preschool children responded. According to caregiver reports, 102/410 (24.9% children had S-ECC. Further, 65.0% responded that their child had already undergone treatment for caries. Children with S-ECC were significantly older than those without. S-ECC was also associated with paternal education levels and employment status, and maternal smoking during pregnancy. Breastfed children were less likely to have S-ECC, while consuming drink crystal beverages in bottles, and daily intake of soft drinks, juice, sweets and fast food were associated with increased risk. Those who reported that healthcare services were not available and were not culturally appropriate were significantly more likely to have children with S-ECC. Conclusions. Caregiver reports suggest that nearly 1 in every 4 children has been affected by S-ECC. Identified risk factors for Manitoba First Nations children included age, education and employment, dietary practices

    Full Text Available Although several studies have shown short term health benefits of exclusive breastfeeding (EBF, its long term consequences have not been studied extensively in low-income contexts. This study assessed the impact of an EBF promotion initiative for 6 months on early childhood caries (ECC and breastfeeding duration in children aged 5 years in Mbale, Eastern Uganda.Participants were recruited from the Ugandan site of the PROMISE- EBF cluster randomised trial (ClinicalTrials.gov no: NCT00397150. A total of 765 pregnant women from 24 clusters were included in the ratio 1:1 to receive peer counselled promotion of EBF as the intervention or standard of care. At the 5 year follow-up, ECC was recorded under field conditions using the World Health Organization's decayed missing filled tooth (dmft index. Adjusted negative binomial and linear regression were used in the analysis.Mean breastfeeding duration in the intervention and control groups (n=417 were 21.8 (CI 20.7-22.9 and 21.3(CI 20.7-21.9 months, respectively. The mean dmft was 1.5 (standard deviation [SD] 2.9 and 1.7 (SD 2.9 in the intervention and control groups, respectively. Corresponding prevalence estimates of ECC were 38% and 41%. Negative binomial regression analysis adjusted for cluster effects and loss-to-follow-up by inverse probability weights (IPW showed an incidence-rate ratio (IRR of 0.91 (95% CI 0.65-1.2. Comparing the effect of the trial arm on breastfeeding duration showed a difference in months of 0.48 (-0.72 to 1.7.PROMISE EBF trial did not impact on early childhood caries or breastfeeding duration at 5 years of age. This study contributes to the body of evidence that promotion of exclusive breastfeeding does not raise oral health concerns. However, the high burden of caries calls for efforts to improve the oral health condition in this setting.ClinicalTrials.gov NCT00397150.

    Full Text Available Sucrose, extracellular polysaccharide, and glucosyltransferases (GTFs are key factors in sucrose-dependent adhesion and play important roles in the process of severe early-childhood caries (S-ECC. However, whether sucrose concentration regulates gtf expression, extracellular polysaccharide synthesis, and sucrose-dependent adhesion is related to the different genotypes of S. mutans isolated from ECC in children and still needs to be investigated. In this study, 52 strains of S. mutans were isolated from children with S-ECC and caries-free (CF children. Water-insoluble glucan (WIG synthesis was detected by the anthrone method, adhesion capacity by the turbidimetric method, and expression of gtf by RT-PCR in an in vitro model containing 1%–20% sucrose. The genotypes of S. mutans were analyzed by AP-PCR. The results showed that WIG synthesis, adhesion capacity, and gtf expression increased significantly when the sucrose concentration was from 1% to 10%. WIG synthesis and gtfB as well as gtfC expression of the 1% and 5% groups were significantly lower than those of the 10% and 20% groups (p < 0.05. There were no significant differences between the 10% and 20% groups. The fingerprints of S. mutans detected from individuals in the S-ECC group exhibited a significant difference in diversity compared with those from CF individuals (p < 0.05. Further, the expression of gtfB and gtfC in the S-ECC group was significantly different among the 1- to 5-genotype groups (p < 0.05. It can be concluded that sucrose-dependent adhesion might be related to the diversity of genotypes of S. mutans, and the 10% sucrose level can be seen as a “turning point” and essential factor for the prevention of S-ECC.

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

    Full Text Available Purpose: Genetic factor to bitter taste perception appears to be largely mediated by the TAS2R38 gene. The insensitivity to bitter compounds like 6-n-propylthiouracil (PROP is mediated by this gene. PROP, a pharmacological drug used in treatment of Graves′ disease, proved to be useful tool in determining the genetic sensitivity levels to bitter and sweet taste. The purpose of this study is to show much simpler PROP sensitivity technique for the clinical examiner and its application as a diagnostic aid in Early Childhood Caries (ECC detection among preschool children. Materials and Methods: A total of 119 children belonging to the age group of 36 to 71 months of both sexes, were recruited from A. J. Institute of Dental Sciences, Mangalore (Karnataka. PROP sensitivity test was carried out to determine the inherent genetic ability to taste a bitter or sweet substance. This study used simpler scaling method to find out genetic sensitivity to bitter taste; one who tasted bitter as taster and one who was not able to differentiate/tasted like paper as non-taster. A questionnaire was provided to evaluate their dietary habits and caries experience was recorded. Collected data were tabulated and subjected to statistical analysis. Results: In the total of 119 children the mean dmfs was definitely higher in non-taster children compared to tasters. The tasters had a mean dmfs value of 9.5120 (S.D. 7.0543 and non-tasters had a value of 7.7250 (S.D. 8.33147, which was statistically significant. The results suggested that there was increase in caries experience among the group of non-tasters as compared to tasters. Tasters tended to be sweet dislikers and non-tasters tended to be sweet likers. On the whole, tasters had a bad dentition as compared to non tasters. Conclusion: The PROP sensitivity test (filter paper test proved to be a useful diagnostic tool in determining the genetic sensitivity levels of bitter taste. The knowledge of a child′s taste

    Perinatal and background risk factors for autism were identified in a cohort of autistic children in Zhengzhou, China, to formulate preventative and treatment strategies for high-risk families. In this case-control study, children were screened for suspected autism using the Autism Behavior Checklist (ABC) and diagnosed according to DSM-IV and the Childhood Autism Rating Scale (CARS). We collected perinatal histories and clinical data of 286 confirmed autistic children treated at the Third Affiliated Hospital Children׳s Psychological Clinic of Zhengzhou University from 2011 to 2013. The control group consisted of 286 healthy children from area kindergartens. Maternal age>30 years, parental introversion as measured by the Eysenck Personality Questionnaire, low level of parental education, smoking, abortion threat, pregnancy complications, maternal illness during pregnancy, maternal mental health, family history of mental illness, neonatal jaundice, birth asphyxia, premature rupture of the fetal membrane, and gestational ageautism group. These factors were significantly correlated with behavioral symptoms as measured by ABC scores (Kendall rank correlation). Birth asphyxia, neonatal jaundice, maternal age, parental introversion, family history of mental illness, abortion threat, premature delivery, and smoking were identified as independent risk factors by multivariate logistic regression.

    Full Text Available Objective: To evaluate the antibacterial action of Amalgomer CR and Fuji VII against bacteria causing S-early childhood caries. Materials and Methods: Antibacterial activity of Amalgomer CR and Fuji VII was assessed using the agar diffusion test in triplicate. The powder and liquid of each test material was mixed and inserted in the punched wells (6 mm × 2 mm. A composition of 0.2% chlorhexidine digluconate acted as control. The agar plates were incubated at 37°C for 24 h for Streptococcus mutans, S. salivarius, S. parasanguinis and Actinomyces viscosus, whereas Lactobacillus casei was incubated for 48 h. Sizes of the inhibition zones were calculated by subtracting the diameter of the specimen (6 mm from the average of the three measurements of the halo. For each test material against each bacteria, 9 measurements were made (3 measurements × 3 times. Kruskal-Wallis test was done to compare the zones of inhibition of test materials against individual bacteria. Pair-wise comparison was done by Mann-Whitney U-test. Results: Amalgomer CR had the most antibacterial against S. mutans (31.0 mm, followed by A. viscosus (21.87 mm, S. salivarius (13.87 mm, S. parasanguinis (10.80 mm, and L. casei (9.69 mm. Fuji VII had the most antibacterial action against S. salivarius (10.65 mm, followed by A. viscosus (9.10 mm. However, it did not inhibit the growth of S. mutans (0 mm, S. parasanguinis (0 mm, and L. casei (0 mm. Conclusion: Amalgomer CR and Fuji VII showed wide variation in antibacterial action against all test organisms.

FONTES DOS DADOS: Foi realizada busca de artigos científicos utilizando-se as bases de dados MEDLINE, Lilacs e SciELO, páginas de internet relevantes, livros técnicos e publicações de consenso de organismos nacionais e internacionais. As palavras-chave utilizadas foram: early childhood caries, dental caries, dental decay e breastfeeding. Percebida a relevância, também se buscou diretamente as referências indicadas nos artigos encontrados. SÍNTESE DOS DADOS: Os estudos que relacionam a cárie com o aleitamento materno invariavelmente só observam os fatores inter-relacionados com o surgimento dessa doença, deixando de lado aqueles associados à amamentação. Muitos desses fatores atuam como variáveis de confusão porque, do mesmo modo que interferem no aleitamento materno, também têm influência no surgimento da cárie. Além disso, estudos atuais têm demonstrado a cariogenicidade de vários alimentos dados às crianças e a não-cariogenicidade do leite materno. CONCLUSÕES: Não há evidências científicas que comprovem que o leite materno possa estar associado com o surgimento de cárie, sendo essa relação complexa e confundida por muitas variáveis.OBJECTIVE: To find scientific evidences that can prove or refute the assumption that nocturnal and on demand breastfeeding are associated with caries in infants and preschool children.

    Full Text Available Este estudo tem por objetivo investigar a relação existente entre a desnutrição energético-protéica e a cárie dentária precoce na primeira infância. Trata-se de uma comunicação, para a qual foi realizada uma revisão da literatura, a partir de análise documental de produção bibliográfica, baseada em levantamentos de periódicos e consultas a livros. Verificou-se que a cárie precoce na infância é altamente prevalente nas comunidades de baixa renda, nas quais a desnutrição é um fator comum e de grande relevância. Estudos mostram que crianças desnutridas tendem a apresentar defeitos estruturais no esmalte do dente, como também estão predispostas a um maior risco à cárie dentária. Portanto, uma deficiência energético-protéica durante a fase de desenvolvimento dentário (odontogênese tem demonstrado uma maior suscetibilidade à cárie dentária, atraso na cronologia de erupção e defeitos estruturais do esmalte (hipoplasia de esmalte, hipofunção das glândulas salivares e mudança na composição da saliva. Estes fatores podem ser os mecanismos pelos quais a desnutrição associa-se à cárie. Em conclusão, os estudos sugerem que a deficiência energético-protéica durante a odontogênese gera atraso na cronologia de erupção e defeitos estruturais no esmalte (hipoplasia, além de poder afetar as glândulas salivares, aumentando o risco de ocorrência da doença cárie.

    A diagnostic test is particularly beneficial if it reveals the level of susceptibility prior to onset of a disease process. In the case of childhood caries, such a diagnostic test affords the opportunity for preventive measures to be implemented before caries begins. Salivary glycoproteins contain a wealth of individually specific oligosaccharide motifs. Depending on microbial compatibilities and individual genotypes, the glycoproteins that form the pellicle coating of teeth may provide attachment sites that foster colonization leading to cariogenesis. Alternatively, certain oligosaccharides, when present in nonpellicle glycoproteins, can interact with planktonic bacteria and lower their ability to interact with the tooth surface. We have found that in young adults the ratio of the two classes of oligosaccharides present in resting saliva exhibits a strong correlation with caries history (DFT: number of decayed and filled teeth). Oligosaccharide moieties associated with the test are quantitated in dried spots of whole saliva on nitrocellulose using commercially available biotinylated lectins with a variety of reporters. A combination of multiple linear regression and neural net analyses were used to develop the algorithms that describe the relationship between oligosaccharide patterns and DFT. During test development several different groups of adults and children have been studied. The correlation algorithms routinely exceed an R(2) (coefficient of determination) of 0.96. When the test is applied to the saliva of children, it yields a projection of their future caries history. Modifying the test result metric to reflect the groups of teeth with caries in young adults, the test identifies those teeth at risk for future caries in children. This test outcome can then be accompanied with suggested specific preventive measures for each tooth group-based risk level.

    Full Text Available Background and Aim: Childhood overweight and obesity are becoming a major public health concern all over the world. Change in lifestyles and economic growth have led to sedentary lifestyle and altered dietary patterns. There are conflicting reports in the literature regarding the association between body mass index (BMI and dental caries from various parts of the world. The aim of the present study was to determine if there is an association between BMI-for-age and dental caries in children and to find out the role of diet with respect to BMI-for-age and dental caries. Materials and Methods: Demographics and anthropometric measurements were obtained for 600 children and BMI-for-age was calculated. Clinical examination for dental caries was carried out following WHO criteria. A diet recording sheet was prepared and children/parents were asked to record the dietary intake for 3 days. Data obtained were statistically analyzed using Chi-square, analysis of variance (ANOVA, and multiple linear regression. Results: After excluding improperly filled diet recording sheets, 510 children were included in the study. Caries prevalence was more in obese children than in other BMI groups. Caries scores increased as BMI-for-age increased, though this was not statistically significant. Consumption of fatty foods and snacks was more with obese children compared to other groups. A correlation was found between caries and snacks. Conclusion: Dental caries scores showed no relationship between BMI-for-age in children. Both snacks and fatty food items were consumed more by obese children, which seeks attention.

Poor nutrition, lack of physical activity, and obesity in children have important public health implications but, to date, their effects have not been studied in the growing population of children in Sweden with immigrant parents. Methods. We estimated the association between parental migration background and nutrition, physical activity, and weight in 8-year-old children born in Stockholm between 1994 and 1996 of immigrants and Swedish parents (n=2589. Data were collected through clinical examination and questionnaires filled out by parents. Odds ratios (ORs and 95% confidence intervals (95% CIs were calculated using multivariable logistic regression. Results. Children of immigrants complied more closely with Nordic Nutrition Recommendations compared with those of Swedes (OR = 1.35, 95% CI 1.11–1.64. They had higher intake of dietary fibre, vitamins C, B6, and E, folic acid, and polyunsaturated fatty acids (omega-3 and omega-6 reflecting higher consumption of foods of plant origin, but lower intake of vitamins A and D, calcium, and iron reflecting lower consumption of dairy products. Children of immigrants had higher intake of sucrose reflecting higher consumption of sugar and sweets. Furthermore, these children had a higher risk of having low physical activity (OR = 1.31, 95% CI 1.06–1.62 and being overweight (OR = 1.33, 95% CI 1.06–1.65 compared with children of Swedish parents. The odds of having low physical activity and being overweight were even higher in children whose parents were both immigrants. A low level of parental education was associated with increased risk of low physical activity regardless of immigration background. Conclusions. Culturally appropriate tools to capture the diverse range of ethnic foods and other lifestyle habits are needed. Healthcare professionals should be aware of the low levels of physical activity, increased weight, and lack of consumption of some important vitamins among children of

However, the extent to which malnutrition affects developmental and cognitive outcomes in the midst of co-occurring risk factors remains largely understudied. We sought to establish if the effects of nutritional status varied according to diverse background characteristics as well as to compare the relative strength of the effects of poor nutritional status on language skills, motor abilities and cognitive functioning at school age. This cross-sectional study was conducted among school-age boys and girls resident in Kilifi District in Kenya. We hypothesized that the effects of area of residence, school attendance, household wealth, age and gender on child outcomes are experienced directly and indirectly through child nutritional status. The use of structural equation modelling (SEM allowed the disaggregation of the total effect of the explanatory variables into direct effects (effects that go directly from one variable to another and indirect effects. Each of the models tested for the four child outcomes had a good fit. However, the effects on verbal memory apart from being weaker than for the other outcomes, were not mediated through nutritional status. School attendance was the most influential predictor of nutritional status and child outcomes. The estimated models demonstrated the continued importance of child nutritional status at school-age.

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

    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.

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

    Background An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. Materials and methods A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Results Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. Conclusions These observations further document the potential protective effects of dental calculus mineralization against dental caries. PMID:27446993

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

    Full Text Available Abstract Background Secondhand smoke exposure (SHSe is perhaps one of the most important toxic exposures in childhood. However, epidemiological studies on the relation between SHSe and dental caries are limited and have yielded inconsistent results. The present cross-sectional study examined the potential association between SHSe at home and the prevalence of dental caries in children. Methods Subjects were 20,703 schoolchildren aged 6 to 15 years in Okinawa, Japan. Information on SHSe at home and potential confounding factors was obtained through questionnaires. Data on dental caries were obtained from school records. Children were classified as having decayed and/or filled teeth (DFT if a dentist diagnosed these conditions. Additionally, we analyzed decayed teeth (DT and filled teeth (FT separately. Adjustment was made for sex, age, region of residence, toothbrushing frequency, use of fluoride, sugar intake, and paternal and maternal educational level. Results The prevalence of DFT was 82.0%. Compared with never smoking in the household, former and current household smoking were independently associated with an increased prevalence of DFT (adjusted prevalence ratios [95% confidence intervals] for former household smoking and current light and heavy household smoking were 1.03 [1.00-1.05], 1.04 [1.02-1.05], and 1.04 [1.03-1.06], respectively; when analyzed separately there was an increased prevalence of DT (adjusted prevalence ratios [95% confidence intervals] for former household smoking and current light and heavy household smoking were 1.06 [1.02-1.11], 1.10 [1.06-1.13], and 1.10 [1.07-1.14], respectively but not FT. A statistically significant dose-response relationship between cumulative smoking in the household and the prevalence of DFT and DT (P for trend Conclusion Our findings suggested that household smoking might be associated with an increased prevalence of dental caries in children.

    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

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

    2008-03-01

    Full Text Available Background: Early childhood caries (ECC is one of the most common diseases of childhood. The etiology of ECC is multifactorial and both genetic and environmental factors play important roles in the pathogenesis of the disease. Genetic variations in the hosts may contribute to changes in the risk for dental caries. Genetic factors such as human leukocyte antigen (HLA have recently been suggested as a predisposing factor. Aim: The aim of this study was to look for an association between HLA-DRB1 and HLA-DQB1 with ECC for developing new strategies for the diagnosis as well as the prevention of the disease. Design: In this study, we extracted the genomic DNAs from whole blood samples of 44 patients with ECC and 35 caries-free children by the salting-out method. We amplified the genomic DNA by PCR-SSP and then HLA-typing was performed for all alleles. Results: The results revealed a significant increase in the frequency of HLA-DRB1FNx0104 in the patient group (P = 0.019. The odds ratio for this allele was detected to be 10. The frequency of HLA-DQB1 alleles was not significantly different between the two groups. Conclusion: The above results suggest that HLA-DRB1FNx0104 is associated with the susceptibility to ECC. Thus HLA-DRB1FNx0104 detection as a molecular marker for early diagnosis of ECC may be recommended.

    Background Streptococcus mutans (S.mutans) is the prime pathogen of dental caries.There are few reports that studied the relationship between S.mutans,bacteria and dental caries in permanent teeth when compared to those in primary teeth.This study aimed to detect S.mutans and bacteria of dental caries and non-caries groups in permanent teeth from a north China population by real-time polymerase chain reaction (PCR) and compare the relationship between the number of these bacteria and the prevalence of dental caries in permanent teeth.Methods Human saliva samples were collected from 142 subjects with permanent teeth.According to their dental tooth (DT),142 subjects were divided into a dental caries group (DT≥1) and a non-caries group (DT=0).With specific primers for S.mutans and 16S rRNA,the total number of S.mutans and total bacteria of 142 saliva samples were detected by real-time PCR and statistically analyzed.Results There was no significant difference between the detection rates of S.mutans (P=0.118) and medians of S.mutans (P=0.115).The ratio of S.mutans to total bacteria in people with dental caries was significantly higher than in those without caries (P <0.001),but the total number of bacteria in people with dental caries was significantly lower than in those without caries (P <0.001).Conclusions S.mutans had different effects on caries in the permanent teeth of several individuals from a north China population.The ratios of S.mutans to total bacteria in saliva detected by real-time PCR with Sm479F/R and 16S RNA primers were closely associated with the prevalence of dental caries in the same population.These assays may be useful for the assessment of an individual's risk of dental caries.

    Full Text Available Ependymal tumors are the third most common group of brain tumors in children, accounting for about 10% of all primary brain neoplasms. According to the current WHO classification, they comprise four entities with the most frequent ependymoma and anaplastic ependymoma. The most of pediatric tumors are located within the posterior fossa, with a tendency to infiltrate the vital brain structures. This limits surgical resection and poses a considerable clinical problem. Moreover, there are no appropriate outcome prognostic factors besides the extent of surgical resection. Despite definition of molecular subgroups, the majority of childhood ependymomas present a balanced genome, which makes it difficult to establish molecular prognostic factors.The purpose of our study was to explore whether miRNA expression could be used as prognostic markers in pediatric infratentorial ependymomas. We also performed a mRNA expression pattern analysis of NELL2 and LAMA2 genes, with immunohistochemical illustrations of representative cases. The miRNA and mRNA expression was measured in 53 pediatric infratentorial ependymomas using a real-time quantitative PCR.Three miRNAs were shown to efficiently differentiate between grade II and III ependymomas: miR-17-5p, miR-19a-3p, and miR-106b-5p. Survival analysis showed that the probabilities of overall (p = 0.036 and event-free survival (p = 0.002 were reduced with higher than median miRNA expression levels of miR-17-5p. Using multivariate analysis adjusted for patient's age, sex, tumor grade and localization, we showed statistically significant associations with event-free survival (p = 0004 and borderline statistical significance with overall survival (p = 0.057 for miR-17-5p. Correlation analysis of miR-19a, miR-17-5p, miR-106b revealed that their expression levels were significantly correlated with EZH2 expression, suggested marker of PFA ependymomas. Furthermore, lower expression level of LAMA2 mRNA was shown to be

    Full Text Available Abstract Background Dental caries is a chronic disease with plaque bacteria, diet and saliva modifying disease activity. Here we have used the PLS method to evaluate a multiplicity of such biological variables (n = 88 for ability to predict caries in a cross-sectional (baseline caries and prospective (2-year caries development setting. Methods Multivariate PLS modelling was used to associate the many biological variables with caries recorded in thirty 14-year-old children by measuring the numbers of incipient and manifest caries lesions at all surfaces. Results A wide but shallow gliding scale of one fifth caries promoting or protecting, and four fifths non-influential, variables occurred. The influential markers behaved in the order of plaque bacteria > diet > saliva, with previously known plaque bacteria/diet markers and a set of new protective diet markers. A differential variable patterning appeared for new versus progressing lesions. The influential biological multimarkers (n = 18 predicted baseline caries better (ROC area 0.96 than five markers (0.92 and a single lactobacilli marker (0.7 with sensitivity/specificity of 1.87, 1.78 and 1.13 at 1/3 of the subjects diagnosed sick, respectively. Moreover, biological multimarkers (n = 18 explained 2-year caries increment slightly better than reported before but predicted it poorly (ROC area 0.76. By contrast, multimarkers based on previous caries predicted alone (ROC area 0.88, or together with biological multimarkers (0.94, increment well with a sensitivity/specificity of 1.74 at 1/3 of the subjects diagnosed sick. Conclusion Multimarkers behave better than single-to-five markers but future multimarker strategies will require systematic searches for improved saliva and plaque bacteria markers.

    Full Text Available Caries remains the most prevalent non-contagious infectious disease in humans. It is clear that the current approaches to decrease the prevalence of caries in human populations, including water fluoridation and school-based programs, are not enough to protect everyone. The scientific community has suggested the need for innovative work in a number of areas in cariology, encompassing disease etiology, epidemiology, definition, prevention, and treatment. We have pioneered the work on genetic studies to identify genes and genetic markers of diagnostic, prognostic, and therapeutic value. This paper summarizes a presentation that elaborated on these initial findings.

    Full Text Available Adolescent rampant caries is a new and growing challenge in Conservative Dentistry. It has the same etiology and pattern as that of nursing bottle syndrome. Herein, a case is presented in which the main cause of rampant caries is the patient′s habit of keeping cariogenic food in her mouth and going to sleep. Educating this etiology and introduction of preventive strategies not only assists in meeting the special oral needs of the adolescent population, but also helps to establish lifelong healthful habits.

  18. Sex differences in dental caries experience: clinical evidence, complex etiology.

    Science.gov (United States)

    Lukacs, John R

    2011-10-01

    A sex difference in oral health has been widely documented through time and across cultures. Women's oral health declines more rapidly than men's with the onset of agriculture and the associated rise in fertility. The magnitude of this disparity in oral health by sex increases during ontogeny: from childhood, to adolescence, and through the reproductive years. Representative studies of sex differences in caries, tooth loss, and periodontal disease are critically reviewed. Surveys conducted in Hungary, India, and in an isolated traditional Brazilian sample provide additional support for a significant sex bias in dental caries, especially in mature adults. Compounding hormonal and reproductive factors, the sex difference in oral health in India appears to involve social and religious causes such as son preference, ritual fasting, and dietary restrictions during pregnancy. Like the sex difference in caries, tooth loss in women is greater than in men and has been linked to caries and parity. Results of genome wide association studies have found caries susceptible and caries protective loci that influence variation in taste, saliva, and enamel proteins, affecting the oral environment and the micro-structure of enamel. Genetic variation, some of which is X-linked, may partly explain how sex differences in oral health originate. A primary, but neglected, factor in explaining the sex differential in oral health is the complex and synergistic changes associated with female sex hormones, pregnancy, and women's reproductive life history. Caries etiology is complex and impacts understanding of the sex difference in oral health. Both biological (genetics, hormones, and reproductive history) and anthropological (behavioral) factors such culture-based division of labor and gender-based dietary preferences play a role.

    Full Text Available Abstract Background Childhood obesity in rural communities is a serious but understudied problem. The current experiment aims to assess a wide range of obesity risk factors among rural youth and to offer an 8-month intervention program for parents to reduce obesity risk in their preteen child. Methods/Design A two-group, repeated measures design is used to assess the effectiveness of the 4-Health intervention program. Assessments include anthropometric measures, child self-evaluations, parent self-evaluations, and parent evaluations of child. County Extension agents from 21 rural Montana counties recruit approximately 150 parent–child dyads and counties are semi-randomly assigned to the active intervention group (4-Health Educational Program or a “best-practices” (Healthy Living Information control group. Discussion This study will shed light on the effectiveness of this parent-only intervention strategy in reducing obesity risk factors among rural preteens. The 4-Health program is designed to provide information and skills development for busy rural parents that will increase healthy lifestyles of their preteen children and improve the parents’ ability to intervene effectively in the lives of their families during this critical developmental period.

    2015-01-01

    Full Text Available Background: Today, most approaches to caries viewed that catastrophic change in normal plaque biofilm is responsible for the disease. The behavior and composition of the biofilm are a reflection of the oral environment; the caries is a reflection of adverse changes occurring in that environment. Thus, it is important to identify the pathogenicity of the plaque biofilm so as to predict the caries risk. The recently developed three-tone plaque disclosing agent was used to test its ability in identifying the pathogenicity of plaque. Aim: To assess the efficacy of three-tone plaque disclosing agent in identifying the plaque pathogenicity and correlate with the clinical caries status and microbiological findings. Materials and Methods: Sixty children of 6-13 years age group of both sexes were clinically examined for caries and plaque scores, and then disclosing agent was applied; the color stained plaque samples were collected and cultured for microbiological assessment, and the data were analyzed based on the caries status of the children. Results: There was a significant difference between the pathological plaque of caries active and caries free group (P < 0.05. The pathological plaque scores and the total colony counts, Streptococcus counts and mutans streptococci counts increased with the increase in caries. Conclusion: Three-tone plaque disclosing agent was effective in identifying pathological plaque and can be used as one of the chairside adjuvants in caries risk assessment.

  3. Drugs that promote dental caries.

    Science.gov (United States)

    2015-02-01

    Dental caries result from erosion of tooth enamel or cementum by acidic substances produced by bacteria found in dental plaque. Caries can lead to pulp necrosis and tooth loss. Risk factors include certain dietary habits, poor oral hygiene, and dry mouth. Diabetes and Sjogren's syndrome can also promote dental caries. Psychotropic substances such as cocaine, methamphetamine, heroin and cannabis can promote dental caries. Many medicinal drugs facilitate the formation of dental caries, through various mechanisms; they include formulations with a high sugar content; drugs that cause dry mouth (especially antimuscarinics); drugs that lower the buccal pH (inhaled powders, etc.); and drugs that cause demineralisation (tetracyclines, etc.). In practice, patients (and parents) should be informed that some drugs can increase the risk of dental caries. They should be encouraged to adapt and reinforce dental hygiene, and advised to visit a dentist regularly.

    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.

    Full Text Available Abstract Background With the increasingly polarized distribution of dental caries among children and adolescents, the usual DMFT measure has become a less meaningful population descriptor. To re-focus on identifying the high caries prevalence group the Significant Caries Index (SiC was created. The aims of this study were to analyze the prevalence and severity of dental caries in Nevada youth over a period of eight years and to compare its expression by means of DMFT and SiC; analyze the caries trends in the population and their underlying factors, and determine whether Nevada youth were at risk for significantly high levels of dental caries. Methods Retrospective data was analyzed from a series of sequential, standardized oral health surveys across eight years (2001/2002-2008/2009 that included over 62,000 examinations of adolescents 13-19 years of age, attending public/private Nevada schools. Mean Decayed-Missing-Filled Teeth index (DMFT and Significant Caries Index (SiC were subsequently computed for each academic year. Descriptive statistics were reported for analysis of comparative DMFT and SiC scores in relation to age, gender, racial background, and residence in a fluoridated/non-fluoridated community. Logistic regression analysis was used to analyze the differential impact of the variables on the probability of being in the high caries prevalence group. Results Comparison of students' mean DMFT to National (NHANES data confirmed that dental caries remains a common chronic disease among Nevada youth, presenting higher prevalence rates and greater mean scores than the national averages. Downward trends were found across all demographics compared between survey years 1 and 6 with the exception of survey year 3. An upward trend began in survey year six. Over time, the younger group displayed an increasing proportion of cariesfree individuals while a decreasing proportion was found among older examinees. As expected, the mean SiC score was

    Full Text Available The aim of this study was to assess the prevalence of caries and risk factors in outpatients of the Pediatric Ambulatory of the Pedro Ernesto University Hospital aging up to 36 months. After signing informed consent forms, the parents answered a structured questionnaire in order to evaluate risk factors for dental caries, including socioeconomic status, oral hygiene and dietary habits. A single investigator carried out the dental examination which assessed the presence of caries, biofilm and gingival bleeding. The data were analyzed by means of the Epi Info program, utilizing the chi-squared test. The children?s mean age was 22.9 months. The prevalence of caries, including white spot lesions, was 41.6%, and the mean def-s was 1.7 (± 2.5. The most affected teeth were the maxillary incisors, and the most common lesion was the white spot. No significant associations were found between the prevalence of caries and socioeconomic status, frequency of oral hygiene, nocturnal bottle- and breast-feeding or cariogenic food and beverage intake during the day. However, the association between caries and oral hygiene quality (dental biofilm was statistically significant (p < 0.001. The results suggest that the presence of a thick biofilm was the most important factor for the occurrence of early childhood caries in the evaluated sample.

Design: Non-cavitated enamel caries lesions (n=15 and dentin caries lesions samples (n=12 were collected from 13 individuals. RNA was extracted and cDNA was constructed, which was used to amplify the 16S rRNA gene. The resulting 780 bp polymerase chain reaction products were pyrosequenced using Titanium-plus chemistry, and the sequences obtained were used to determine the bacterial composition. Results: A mean of 4,900 sequences of the 16S rRNA gene with an average read length of 661 bp was obtained per sample, giving a comprehensive view of the active bacterial communities in caries lesions. Estimates of bacterial diversity indicate that the microbiota of cavities is highly complex, each sample containing between 70 and 400 metabolically active species. The composition of these bacterial consortia varied among individuals and between caries lesions of the same individuals. In addition, enamel and dentin lesions had a different bacterial makeup. Lactobacilli were found almost exclusively in dentin cavities. Streptococci accounted for 40% of the total active community in enamel caries, and 20% in dentin caries. However, Streptococcus mutans represented only 0.02–0.73% of the total bacterial community. Conclusions: The data indicate that the etiology of dental caries is tissue dependent and that the disease has a clear polymicrobial origin. The low proportion of mutans streptococci

    Reports that compare dental caries indices in HIV-seropositive (HIV+) subjects with HIV-seronegative (HIV-) subjects are rare. The objective of this study was to determine if there was an association between HIV infection and dental caries among women enrolled in the Women's Interagency HIV Study. Subjects included 538 HIV+ and 141 HIV- women at baseline and 242 HIV+ and 66 HIV- women at year 5. Caries indices included DMFS and DFS (coronal caries) and DFSrc (root caries). Cross-sectional analysis of coronal caries data revealed a 1.2-fold-higher caries prevalence among HIV+ women compared with HIV- women. Longitudinally, DMFS increased with increasing age and lower average stimulated salivary volume. Root caries results were not significant except for an overall increased DFSrc associated with smoking. Anti-retroviral therapy was not identified as a risk factor for dental caries.

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

    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: Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH. Materials and Methods: Totally, 76 female students within the age group of 18-23 years were clinically examined, and their decayed, missing, filled teeth (DMFT) score and oral hygiene index-simplified were recorded. Based on their DMFT score, they were divided into following three groups; group I (n = 16, DMFT score = 0), group II (n = 30, DMFT score Dermatoglyphic pattern distribution in caries-free group showed more ulnar loops than high caries group (group III) while high caries group showed more whorl patterns. Presence of whorl with double loop, whorl within a loop was associated with high DMFT score. The total finger ridge count was lower in caries group. The mean salivary pH was higher in caries-free group than high caries group. Thus, we conclude that dermatoglyphic patterns may be potential diagnostic tool for detecting patients prone to develop dental caries. PMID:26283816

    2009-01-01

    Full Text Available Background: The diagnosis of dental caries is fundamental to the practice of dentistry. Despite the fact that dental caries has declined considerably, it is still a problem of great importance. The reduction in caries prevalence has not occurred uniformly for all the surfaces. The greatest reduction was observed at lesions located on smooth surfaces, so that occlusal caries are most common in children. Aim: The purpose of this study is to determine the clinical efficacy of DIAGNOdent in detecting occlusal caries. Materials and Methods: A total number of 50 teeth were subjected for visual, radiographic, and DIAGNOdent examinations. All the three methods were compared to histology which is a gold standard. Results: The result obtained showed that DIAGNOdent is superior to visual and radiographic methods in diagnosing occlusal caries.

    Full Text Available Abstract Background This was a retrospective cohort study undertaken to assess the rate and pattern of dental caries development in 6-year-old school children followed-up for a period of 5 years, and to identify baseline risk factors that were associated with 5 years caries experience in Malaysian children. Methods This 5-years retrospective cohort study comprised primary school children initially aged 6 years in 2004. Caries experience of each child was recorded annually using World Health Organization criteria. The rates of dental caries were recorded in prevalence and incidence density of carious lesions from baseline to final examination. Risk assessment was done to assess relative risk for caries after 5 years in children with baseline caries status. Simple and multiple logistic regression analysis were performed to identify significant independent risk factors for caries. Results The sample consisted of 1830 school children. All components of DMFT showed significant differences between baseline and final examination. Filled teeth (FT component of the DMFT showed the greatest increases. Results revealed the initial baseline caries level in permanent dentition was a strong predictor for future caries after 5 years (RR=3.78, 95% CI=3.48-4.10, P0.001. Logistic regression analysis showed significant association between caries occurrence and residence (urban/rural (OR=1.80, Pp observed from baseline and after 5 years was 5.80 persons/100 person-year of observation. The rate of new caries-affected tooth (IDt in the period from baseline and after 5-years was 0.76 teeth/100 teeth-year of observation. Conclusion The majority of 12-year-old school children (70% were caries-free and most of the caries were concentrated in only a small proportion (30% of them. We found that the presence of caries in permanent teeth at the age of 6 years was a strong predictor of future caries development in this population. The strong evidence of early permanent teeth

  9. Health promotion and dental caries

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

    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.

    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.

    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

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.

    Full Text Available Background: One of the causative factors in development of dental caries is microorganisms. Two species of Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are associated with dental caries in human beings. The aim of this study was to investigate the frequency of S. mutans and S. sobrinus in saliva of children with different caries activity and ability to form biofilm and acid susceptibility of these microorganisms. Materials and Methods: This analytical case-control study was performed on 83 preschool children, 4-6 years old. Children were divided into two groups including 41 caries-active and 42 caries-free children. Non-stimulated saliva samples were collected and culture and polymerase chain reaction techniques were used. Statistical analysis was performed using t-test, Chi-square, ANOVA, and Kappa tests. Results: S. mutans and S. sobrinus were found in 65% and 21.6% of the samples respectively. S. mutans was isolated from 75.6% of caries-active and 54.8% of caries-free children. Figures for S. sobrinus were 29.2% and 14.3% respectively. Acid susceptibility of microorganisms isolated from saliva was 87.43 in caries-active children and 94.30 for caries-free children. Biofilm formation of microorganisms in caries-active and caries-free children was 0.77 and 0.73, respectively. Conclusion: Frequency of S. mutans in caries-active children was significantly higher than caries-free children, but the difference in frequency of S. sobrinus was not significant. Acid susceptibility of microorganisms in caries-active children was significantly lower, but the ability to form biofilm was not significantly different in two groups.

    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 The technology advance in recent years determines the need of construction of modern appliances for early diagnosis of dental caries, which are categorized by great precision, non-invasiveness, easy usage and wide availability. Such non-invasive and accurate tool for diagnostics of caries is Caries Detector (LED, Bulgarian product by “Optica Laser”. The detector emits a specific wavelength of near ultraviolet light, which causes fluorescence to porphyrins - metabolic products of the life cycle of caries-inducing bacteria. The purpose of the study is piloting a new diagnostic tool for detection and monitoring of caries excavation based on fluorescence - LED UV caries detector of company “Optica laser”. Subjected to examination by caries indicator dye and UV caries detector were sixty permanent teeth with deep dentine caries. Two methods were used to assess the dentin caries - UV fluorescence detector of “Optica Laser” and staining with caries indicator - dye (Sable ™ Seek®. It was found that among all sixty teeth, the fields, closed by margins of carious process overlap. Fifty-four of tested teeth has shown bigger field of images with staining method and six - smaller in comparison to the fluorescent method. Ultraviolet fLuorescence caries detector of “Optica Laser” company is affordable and easy applicable method for controlled excavation of dentine caries. The detector can be used in daily dental practice equally with other methods. The unit has a number of advantages - non-invasiveness, lack of interaction with tooth structures, speed, reliability, efficiency, predictability and repeatability of results.

    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.

    Early mutans streptococci (MS) infection has been associated with higher caries activity in childhood. Since colonization with MS does not always lead to caries activity, additional factors may be involved in MS cariogenicity. For example, MS may differ in virulence traits such as the potential to synthesize glucan polymers from sucrose. In the present study, we tested the hypothesis that caries activity can be associated with variations in virulence factor expression of MS-infecting strains. At baseline, levels of MS obtained by the tongue-blade sampling method, and the presence of visible plaque on upper incisors, were measured in 101 12- to 30-month-old children. Dental caries lesions were diagnosed at baseline and after one year. Caries incidence data were then used to select ten caries-free and nine caries-active children from whom a total of 20 MS fresh isolates was studied. Water-insoluble glucan (WIG) synthesis, final pH, and sucrose-dependent adherence on glass surfaces were measured in these MS isolates. Concentrated culture supernatants were separated in duplicate SDS-PAGE gels, which were then either stained for protein or incubated with 5% sucrose. The intensities of the WIG bands developed in the 5% sucrose PAGE gels and the corresponding protein-stained GTF bands were measured by scanning densitometry. High MS levels (> or = 100 CFU) were associated with high caries incidence (p development by increasing MS adherence and accumulation in the plaque of young children. PMID:10890715

  20. Current possibilities in occlusal caries management

    Hrvoje Jurić

    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.

    Dental caries is an irreversible microbial disease of the calcified tissues of the teeth and it has a multifactorial origin. In India, the dental caries prevalence in 35-44 year olds was reported to be 80-95% in a DCI survey. Among the elderly in the 65-74 years age group, the DCI survey reported the caries prevalence to be about 70%, while the present survey reported it to be 51- 95% in various states. Surveys which were done on school children in India showed a carie prevalence of approximately 58%.Among the U.S. population, a survey showed an incidence of 93.8% in adults with either past or present coronal caries and an incidence of 45.3% in children 23. In countries like Brazil and China, it is reaching epidemic proportions. Thus, more effective public-health measures are needed to combat dental caries. Mutans streptococci is one of the main microorganisms which are associated with the aetiology of dental caries. Preclinical studies of immunological interventions have shown that the disease can be interrupted. Clinical trials have indicated that a mucosal immune response to Streptococcus mutans crucial antigens can influence the pathogenesis of dental caries. The dental caries vaccine, when it is used in appropriate individuals at the appropriate time, can reduce the reemergence of the disease. PMID:23905153

    Full Text Available The present cohort study examined how lifestyle, household environment, and caries activity test score of Japanese children at age 1.5 years affected their dental caries incidence at age 3. Inclusion criteria were 1.5-year-old children with no dental caries. Dental examinations were performed for 33,655 children who participated in routine dental examinations at 1.5 years of age, and the exam was repeated approximately 21 months later (at age 3 at the Kobe City Public Health Center in Japan. After excluding 622 children who had caries at age 1.5 and 1831 children with missing lifestyle and household environment data in the questionnaires, the final data analysis was performed on a total of 31,202 children (16,052 boys, 15,150 girls.The multivariate logistic regression analysis indicated a strong association of the consumption of sugar-sweetened beverages/snacks, less frequent tooth brushing by the parents, lack of fluoride varnish, family history of smoking, with the risk of developing dental caries. A child’s late bedtime is also one of the major risk factors for dental caries development. Further investigation is needed to examine whether the short duration or the irregularity of the sleep-wake cycle would affect early childhood oral health and whether there is a relationship between late bedtime and late night snack intake.

    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

    Full Text Available The relationship between mother and child in the context of oral health has traditionally been exposed by the scientific literature in microbiology, which lacks a broad and necessary discussion of health and illness seen as processes, both biological and social. Objective: Investigate the family social determinants associated with the caries history of children and the need for dental treatment (NDT among their mothers was the objective of this study. Material and methods: This research employed a cross-sectional study of mother-child pairs living in southern Brazil. Data collection occurred in public institutions of early childhood education. The instruments included a structured questionnaire administered to mothers and clinical oral examinations of the mothers and children. The social variables considered were marital status, maternal education, number of children, income, employment status, and frequency of visits to a dental professional. The measured outcomes were the maternal NDT and child caries history. Data were analyzed by the chi-square test (χ2 and by discriminant analysis. Results: The final sample consisted of 272 mother-child pairs and it was found that the greatest need for treatment was among mothers with low educational level and low family income who rarely or never visited a dentist. Tooth decay was less frequent in only child, and most frequent in children of mothers with low educational attainment, and in children in lower income households who rarely or never visited the dentist. The social determinants of caries in children and of the maternal NDT were similar. It follows that the maternal NDT and caries history among children were strongly associated with maternal education (p<0.0001, household income (p<0.0001, and frequency of visits to a dental professional (0.0018. Caries history among children was also associated with number of children in the household (p<0.0001. Conclusions: The results suggest that the caries

    Dental caries is one of the oldest and most common diseases found in humans. With the recent shift from the surgical model, which emphasized restorative treatment, to a medical model of disease management, newer strategies emphasize disease prevention and conservation of tooth structure. For early detection and monitoring of caries, rather than waiting until a cavity is formed and restorative treatment is needed, devices such as DIAGNOdent, Digital Imaging Fiber-Optic Transillumination, quantitative light-induced fluorescence, and the Electronic Caries Monitor have been introduced. For caries prevention, oral hygiene measures, fluoride application, pit-and-fissure sealants, the use of xylitol, the development of a dental caries vaccine, and the role of the primary caregiver for infants are briefly discussed.

    Full Text Available "nBackground and Aims: Conventional radiological equipments in our country are going to be converted to digital system using computed radiology (CR technology. If we know the accuracy of digital panoramic radiography for detection of small defects in tooth, it will be useful in cases with difficulty for taking the intraoral radiographs. The aim of this study was to evaluate sensitivity and specificity of digital panoramic radiography for detection of proximal caries compared with the bitewing radiography."nMaterials and Methods: One-hundred patients who had been ordered for taking both bitewing and panoramic radiography were included in this study. Panoramic and then bitewing radiographs were observed by a maxillofacial radiologist and interproximal caries were recorded. Sensitivity and specificity of digital panoramic radiography (CI=95% was calculated compared with the bitewing radiography as a gold standard."nResults: This study showed that the values for sensitivity and specificity were 62.7% (CI 95%=57.7%-67.5% and 91.0% (CI 95%=89.2%-92.5%, respectively."nConclusion: Sensitivity of digital panoramic is less than bitewing radiography even with processing before printing. Therefore, bitewing radiography is superior for detection of inter proximal 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 {mu}m and the range of lesional area was 36.95-138.52 mm{sup 2}. 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.

    Full Text Available The aim of the present study was to find the prevalence of nursing caries in Davangere preschool children and its relationship with feeding practices and socioeconomic status of the family. Materials and Methods: A total of 813 children aged 2-6 years were screened for the present study from randomly selected three kindergarten schools each from Government, Government aided, and private managements. Clinical examination was done inside the respective schools. At the time of examination, a proforma was filled for each child comprising of DFS index. The questionnaire by Winter et al. was modified and used in this study. The completed proformas were statistically analyzed to find if any correlation existed between the nursing caries to the feeding practices and socioeconomic status of the family. Results: Duration of breastfeeding increases the number of children with nursing caries and the mean DFS. There is a strong and significant relationship between the severity of nursing caries and the degree of feeding abuse. Children from low socioeconomic status have increased early childhood caries. Conclusion: The prevalence of nursing caries was 19.2% in Davangere preschool population. Nursing caries were more in children who were taking a feeding bottle to bed at night and were increasingly seen in large families and lower socioeconomic groups.

    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.

    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.

    Hungary belongs to those European countries where the intensity of caries is sill very high and the decline in the caries prevalence curve cannot be noticed. Nevertheless reduction in caries incidence were reported in regions with regular administration of fluoride either via fluoridated salts' or fluoride tablets or by means of topical application of fluor. It is very difficult to change the domestic dietary habits and to improve the state oral hygiene. In 1985 a complete preventive program was introduced by a team led by the author based on the three most important fundaments of the caries prevention and the early dental health care system in childhood. Children aged 0 to 6 as well as young elementary school children were given fluoride tablets completed with the use of Elmex Gel in the kindergarten and elementary school. The consumption of fluoride containing toothpastes is steadily increasing in Hungary. Our diet control program is focusing on the reduction of sugar consumption between meals and the introduction of special sweeteners. This is completed with the promotion of special oral hygiene measures and the start of the dental hygienist education program in our country. PMID:1551449

    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 Background: Mechanical method of caries removal is associated with the removal of sound tooth structure, production of pain, heat, annoying sounds, and vibrations. Chemomechanical caries removal method is based on removal of only carious dentin leaving sound dentin intact. Aim: The aim of this study was to compare the efficacy of mechanical and chemomechanical methods of caries removal in deciduous and permanent teeth. Study Design: A total of 30 carious teeth including 15 deciduous and 15 permanent teeth having dentinal caries selected randomly and cut into two halves through center of the lesion, were subjected to caries removal by mechanical (Group A, and chemomechanical methods (Group B. Time taken for removal of caries was noted with stopwatch. Samples were prepared and seen under the scanning electron microscope for the presence of bacterial colonies. Data were analyzed using statistical package for social sciences (SPSS Software. Results: No significant difference was found for the presence of bacterial colonies in both groups of deciduous and permanent teeth; however, time taken for caries removal by the chemomechanical method was twice than the mechanical method. Conclusion: despite the insignificant presence of bacterial colonies and twice time taken as compared to mechanical method, chemomechanical method was easy to introduce, was painless, did not form smear layer and conserved the sound tooth structure.

    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

    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.

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

    2015-02-01

    An ultrathin scanning fiber endoscope, originally developed for cancer diagnosis, was used in a case study to locate plaque and caries. The imaging system incorporated software mitigation of background auto-fluorescence (AF). In conventional fluorescence imaging, varying AF across a tooth surface can mask low-level porphyrin signals. Laser-induced auto-fluorescence signals of dental tissue excited using a 405-nm laser typically produce fluorescence over a wavelength range extending from 440-nm to 750-nm. Anaerobic bacterial metabolism produces various porphyrin species (eg. protoporphyrin IX) that are located in carious enamel, dentin, gingivitis sites, and plaque. In our case study, these porphyrin deposits remained as long as one day after prophylaxis. Imaging the tooth surface using 405-nm excitation and subtracting the natural AF enhances the image contrast of low-level porphyrin deposits, which would otherwise be masked by the high background AF. In a case study, healthy tissues as well as sites of early and advanced caries formations were scanned for visual and quantitative signs of red fluorescence associated with porphyrin species using a background mitigation algorithm. Initial findings show increasing amplitudes of red fluorescence as caries severity increases from early to late stages. Sites of plaque accumulation also displayed red fluorescence similar to that found in carious dental tissue. The use of real-time background mitigation of natural dental AF can enhance the detection of low porphyrin concentrations that are indicators of early stage caries formation.

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.

    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.

    Full Text Available Background: Dental caries is one of the main health problems in children. The first permanent molar presents caries more frequently than any other. Objective: To describe the characteristics of dental caries in the first permanent molars in children between 6 and 13 years-old, and to assess oral hygiene and knowledge about the subject in all the patients treated in the stomatology consultation Barrio adentro “El Guapo”, from November 2005 to March 2006. Methods: A descriptive, transversal study showed that most of the patients had dental caries. It was proved that many of them had, at least, on of the first molars affected by dental caries. The quotient first molar affected/ patient was higher than one. Results: There was a decrease in the percentage of healthy permanent first molars. Poor oral hygiene prevailed, with a medium knowledge level on the subject. Most of the parents didn´t know about the first molar dental cavity. Conclusions: It was needed to perform educative tasks aimed at this age group to avoid further damage to this important tooth, central for the development of the stomatognathic system.

    The microbial ecology of caries is complex and incorporates mechanisms common to the natural colonization of the host and to plaque accumulation at sites that do not develop caries lesions. It is not simply accumulation of plaque in the oral cavity but also the ecology of oral bacteria among the host population and the ecology of organisms in the lesion. In these three habitats odontopathogens and other oral bacteria can undergo genotypic change, which may produce phenotypes more virulent or ...

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

    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

    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.

    Full Text Available Objective In Haiti, families were torn apart and children were left orphans after the 2010 earthquake. In the aftermath of this natural disaster many children were relocated to orphanages across the country and adopted internationally. Years later these children find themselves catching up in growth physically, mentally and emotionally after an extremely traumatic event during a crucial time in their health development. Another important marker of development is the primary dentition and the presence of caries.  We report estimates of early childhood caries (ECC frequency, risk factors and quality of health among Haitian children. Methods Medical and dental professionals conducted a descriptive cross sectional study through the Pittsburgh Kids Foundation and their partnership with IDADEE children’s home, EBAC orphanage and New Vision Children’s home. Vital signs were taken and recorded to create a health/growth history for each child. Brief dental screenings were conducted and topical fluoride treatments were administered. Risk factors and quality of health information was obtained from discussions with the caregivers present. The children and caregivers were given oral hygiene education and supplies (i.e. toothbrushes, toothpaste, floss.  Results Physical exams and dental screenings were conducted on the 40 children ages 3-10 years of age living in the IDADEE children’s home. Two children had cavitated teeth. Eight children had teeth that were stained. Four children had evidence of dental trauma. 26 out of the 40 children had otherwise healthy dentition. Conclusion The IDADEE children’s home and New Vision Children’s home have hopes to expand their capacity with new construction scheduled to be finished in 2016. As more children enter these homes action is needed to educate caregivers on ways to identify high-risk children to prevent ECC and ways they can be treated before irreversible damage is done to the developing permanent

  10. Caries selective ablation: the handpiece

    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.

    Clinical dental examination of 1600 diabetics (815 type 1 insulin dependent and 761 type 2 non-insulin dependent patients) has been performed according to the WHD criteria. According to examination results higher DMF mean value, less uncared of teeth with caries (D) and, in the age group of 19 years and above 30 years, more edentulousness has been found than with healthy individuals. The number of filled and crowded teeth (F) below the age of 35 years in diabetics (p 0.0001), above 45 years in the control group (p 0.0001) was higher. Concerning cared of teeth there was no deviation in the number of filled teeth between diabetic and healthy individuals whereas the number of crown covered teeth was higher with diabetics. (p 0.01). As to the distribution of individuals with healthy teeth and toothless ones it was found characteristic that while among diabetic individuals but 1%, in the control 1.4% possessed retained healthy teeth. The number of completely toothless individuals was higher (11.83%) with diabetics than with healthy individuals (2.25%).

    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

    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.

    Full Text Available BACKGROUND Dental caries is a major and significant oral health condition that affects about 50 to 60% of the population in India among oral diseases. Unfortunately in rural areas oral health care is often limited due to lack of perceived need for dental care among the rural population, financial constraints as well as shortage of dental manpower. AIM This study aims to determine the prevalence of dental caries among the general population of Jagdalpur and also determine the important factors that could have contributed to the disease. SETTING AND DESIGN Case records of patients who reported to the Department of Dentistry were studied retrospectively. Information about decayed, missed, filled teeth, occupation, oral hygiene techniques as well as dental visits was recorded. METHODS AND MATERIAL Retrospective data of 100 patients who visited the Department of Dentistry was collected from the medical records division. Case sheets having incomplete information or patients who were aged below 5 years and above 75 years were not considered for the study. STATISTICAL ANALYSIS Was done using software SPSS 17.0 version. Chi square test (Descriptive Statistics was done to test the significance of nonparametric analysis. P values were considered significant at 0.05% level. RESULTS Of the 100 case records that were examined, dental caries was more prevalent in males than females with asymptomatic significance of both dental caries and missing teeth to be statistically significant. Restored teeth contributed to almost 72.72% of the population. CONCLUSION The prevalence of dental caries among the rural general population is significantly high. Less frequent dental visits and improper or inadequate brushing technique/methods could have contributed to the high incidence of dental caries. Creating awareness regarding proper oral hygiene methods as well as regular dental checkup is recommended.

    2013-01-01

    Background Reliable caries detection is a cornerstone in the modern caries treatment schema. This study aimed to evaluate adopting traditional and new caries detection methods by third-year dental students. Methods Fifty-seven students were given lectures on caries detection, after which they evaluated 27 extracted carious teeth using traditional clinical assessment (CE), Nyvad’s, and ICDAS methods. On three teeth they also performed DIAGNOdent pen® (LF) scanning. Histological scores of the sectioned teeth (ICDAS, LF) and activity estimations of the lesions by the supervisors were used as golden standards (Nyvad, CE). For the ICDAS method , sensitivity and specificity were calculated using dentine caries (D3) as a cut-off point. Mean ICC and kappa values were calculated to evaluate interexaminer agreement for all lesions and methods. Spearman’s correlation coefficient evaluated LF scanning. Results ICDAS method presented good sensitivity (0.78) and specificity (0.87). The inter-examiner agreement for different methods was fair or good (CE ICC = 0.69, κ = 0.53; Nyvad’s method ICC = 0.68, κ = 0.48, ICDAS ICC = 0.66, κ = 0.47). Variation in LF values was the greatest with lesions extending to middle third of dentin. In that case, the Spearman’s correlation coefficient was also the weakest. Conclusions To follow the guidelines by the European Core Curriculum on Cariology, the third year dental students are introduced to methods for detecting lesion depth and assessing lesion activity as well as using new caries detection methods. Their performance in estimating lesion depth is good, and fair to good in estimating lesion activity even after basic training only. PMID:24314305

    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.

    2009-10-01

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

  18. Enamel remineralization: controlling the caries disease or treating early caries lesions?

    Directory of Open Access Journals (Sweden)

    Jaime Aparecido Cury

    2009-06-01

    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".

    2016-01-01

    Background The studies of the distribution of Actinomyces spp. on carious and non-carious root surfaces have not been able to confirm the association of these bacteria with root caries, although they were extensively implicated as a prime suspect in root caries. Objective The aim of this study was to observe the gene expression of Actinomyces spp. in the microbiota of root surfaces with and without caries. Design The oral biofilms from exposed sound root surface (SRS; n=10) and active root caries (RC; n=30) samples were collected. The total bacterial RNA was extracted, and the mRNA was isolated. Samples with low RNA concentration were pooled, yielding a final sample size of SRS=10 and RC=9. Complementary DNA (cDNA) libraries were prepared and sequenced on an Illumina® HiSeq 2500 system. Sequence reads were mapped to eight Actinomyces genomes. Count data were normalized using DESeq2 to analyse differential gene expression applying the Benjamini-Hochberg correction (false discovery rate [FDR]0.05), except for Actinomyces OT178 (p=0.001) and Actinomyces gerencseriae (p=0.004), which had higher read counts in the SRS. Genes that code for stress proteins (clp, dnaK, and groEL), enzymes of glycolysis pathways (including enolase and phosphoenolpyruvate carboxykinase), adhesion (Type-2 fimbrial and collagen-binding protein), and cell growth (EF-Tu) were highly – but not differentially (p>0.001) – expressed in both groups. Genes with the most significant upregulation in RC were those coding for hypothetical proteins and uracil DNA glycosylase (p=2.61E-17). The gene with the most significant upregulation in SRS was a peptide ABC transporter substrate-binding protein (log2FC=−6.00, FDR=2.37E-05). Conclusion There were similar levels of Actinomyces gene expression in both sound and carious root biofilms. These bacteria can be commensal in root surface sites but may be cariogenic due to survival mechanisms that allow them to exist in acid environments and to

  20. Ecological Hypothesis of Dentin and Root Caries.

    Science.gov (United States)

    Takahashi, Nobuhiro; Nyvad, Bente

    2016-01-01

    Recent advances regarding the caries process indicate that ecological phenomena induced by bacterial acid production tilt the de- and remineralization balance of the dental hard tissues towards demineralization through bacterial acid-induced adaptation and selection within the microbiota - from the dynamic stability stage to the aciduric stage via the acidogenic stage [Takahashi and Nyvad, 2008]. Dentin and root caries can also be partly explained by this hypothesis; however, the fact that these tissues contain a considerable amount of organic material suggests that protein degradation is involved in caries formation. In this review, we compiled relevant histological, biochemical, and microbiological information about dentin/root caries and refined the hypothesis by adding degradation of the organic matrix (the proteolytic stage) to the abovementioned stages. Bacterial acidification not only induces demineralization and exposure of the organic matrix in dentin/root surfaces but also activation of dentin-embedded and salivary matrix metalloproteinases and cathepsins. These phenomena initiate degradation of the demineralized organic matrix in dentin/root surfaces. While a bacterial involvement has never been confirmed in the initial degradation of organic material, the detection of proteolytic/amino acid-degrading bacteria and bacterial metabolites in dentin and root caries suggests a bacterial digestion and metabolism of partly degraded matrix. Moreover, bacterial metabolites might induce pulpitis as an inflammatory/immunomodulatory factor. Root and dentin surfaces are always at risk of becoming demineralized in the oral cavity, and exposed organic materials can be degraded by host-derived proteases contained in saliva and dentin itself. New approaches to the prevention and treatment of root/dentin caries are required. PMID:27458979

    2015-01-01

    Background and Objectives Dental caries is an important healthcare challenge in adults over 65 years of age. Integration of oral health screening into non-dental primary care practice may improve access to preventive dental care for vulnerable populations such as the elderly. Such integration would require easy, fast, and accurate early caries detection tools. Primary goal of this study was to evaluate the diagnostic performance of optical coherence tomography (OCT) imaging for detecting very early caries in the elderly living in community-based settings. The International Caries Detection and Assessment System (ICDAS) served as gold standard. Secondary goal of this study was to provide baseline prevalence data of very early caries lesions in independent living adults aged 65+ years. Materials and Methods Seventy-two subjects were recruited from three sites in Southern California: a retirement community, a senior health fair, and a convalescent hospital. Clinical examination was performed using the ICDAS visual criteria and this was followed by OCT imaging. The two-dimensional OCT images (B-scan) were analyzed with simple software. Locations with a log of back-scattered light intensity (BSLI) below 2.9 were scored as sound, and areas equaling or exceeding 2.9 BSLI were considered carious. Diagnostic performance of OCT imaging was compared with ICDAS score. Results OCT-based diagnosis demonstrated very good sensitivity (95.1%) and good specificity (85.8%). 54.7% of dentate subjects had at least one tooth with very early coronal caries. Conclusions Early coronal decay is prevalent in the unrestored pits and fissures of coronal surfaces of teeth in independent living adults aged 65+ years. Though OCT imaging coupled with a simple diagnostic algorithm can accurately detect areas of very early caries in community-based settings, existing devices are expensive and not well-suited for use by non-dental health care providers.

    Full Text Available Background: Dental caries and deviations from normal weight are two conditions which share several broadly predisposing factors. So it′s important to understand any relationship between dental state and body weight if either is to be managed appropriately. Aims: The study was done to find out the correlation between body mass index (BMI, diet, and dental caries among 12-15-year-old schoolgoing children in Panchkula District. Materials and Methods: A multistage sample of 12-15-year-old school children (n = 810 in Panchkula district, Haryana was considered. Child demographic details and diet history for 5 days was recorded. Data regarding dental caries status was collected using World Health Organization (1997 format. BMI was calculated and categorized according to the World Health Organization classification system for BMI. The data were subjected to statistical analysis using chi-square test and binomial regression developed using the Statistical Package for Social Sciences (SPSS 20.0. Results: The mean Decayed Missing Filled Teeth (DMFT score was found to be 1.72 with decayed, missing, and filled teeth to be 1.22, 0.04, and 0.44, respectively. When the sample was assessed based on type of diet, it was found that vegetarians had higher mean DMFT (1.72 as compared to children having mixed diet. Overweight children had highest DMFT (3.21 which was followed by underweight (2.31 and obese children (2.23. Binomial regression revealed that females were 1.293 times at risk of developing caries as compared to males. Fair and poor Simplified-Oral Hygiene Index (OHI-S showed 3.920 and 4.297 times risk of developing caries as compared to good oral hygiene, respectively. Upper high socioeconomic status (SES is at most risk of developing caries. Underweight, overweight, and obese are at 2.7, 2.5, and 3 times risk of developing caries as compared to children with normal BMI, respectively. Conclusion: Dental caries and deviations from normal weight are two

    Young children who are enrolled in Medicaid or the Children’s Health Insurance Program (CHIP) can be at risk for developing early childhood caries (ECC). ECC is a chronic bacterial infection that causes severe tooth decay and can begin to develop before baby teeth erupt. Children with ECC may experience pain, difficulty eating, developmental complications, and loss of days in day care or preschool. ECC is expensive to treat and untreated ECC can lead to other serious infections.

    Full Text Available Objectives. Several groups in Manitoba, Canada, experience early childhood caries (ECC, including Aboriginal, immigrant, and refugee children and those from select rural regions. The purpose of this pilot study was to explore the views of parents and caregivers from four cultural groups on early childhood oral health and ECC. Methods. A qualitative descriptive study design using focus groups recruited parents and caregivers from four cultural groups. Discussions were documented, audio-recorded, transcribed, and then analyzed for content based on themes. Results. Parents and caregivers identified several potential barriers to good oral health practice, including child’s temperament, finances, and inability to control sugar intake. Both religion and genetics were found to influence perceptions of oral health. Misconceptions regarding breastfeeding and bottle use were present. One-on-one discussions, parental networks, and using laypeople from similar backgrounds were suggested methods to promote oral health. The immigrant and refugee participants placed emphasis on the use of visuals for those with language barriers while Hutterite participants suggested a health-education approach. Conclusions. These pilot study findings provide initial insight into the oral health-related knowledge and beliefs of these groups. This will help to inform planning of ECC prevention and research strategies, which can be tailored to specific populations.

    2012-01-01

    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.

  11. Understanding and managing dental caries: a medical approach.

    Science.gov (United States)

    Steinberg, Steve

    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

    2015-04-01

    Full Text Available Background: A previous study revealed Lactobacillus paracasei SD1, a probiotic strain, could reduce mutans streptococci (MS. The aim of this study was to evaluate the long-term effects of L. paracasei SD1 on the colonization of MS, and whether caries lesions developed. Methods: After informed consent, 122 children were recruited and randomly assigned to the probiotic or control groups. The probiotic group received milk-powder containing L. paracasei SD1 and the control group received standard milk-powder once daily for six months. Salivary MS and lactobacilli were enumerated using differential culture at baseline and at three-month intervals for 12 months. The persistence of L. paracasei SD1 was investigated using AP-PCR for DNA-fingerprinting. Oral health was examined at baseline and at the end of the study according to WHO criteria. Results: The long-term consumption could prolong colonization of L. paracasei SD1. Significantly reduced MS counts and increased lactobacilli levels were found among children in the probiotic group. There were less caries lesions in the probiotic group at the end of the study. A significant reduction of the development of new caries lesions (4.5 times was observed in the high caries risk group but not in the low caries risk group. Conclusions: Results demonstrate that the long-term daily ingestion of the human-derived probiotic L. paracasei SD1 significantly reduces the number of MS and caries risk in the high caries group.

    BACKGROUND: Dental caries is the single most prevalent and costly infectious disease worldwide, affecting more than 90% of the population in the U.S. The development of dental cavities requires the colonization of the tooth surface by acid-producing bacteria, such as Streptococcus mutans. Saliva bicarbonate constitutes the main buffering system which neutralizes the pH fall generated by the plaque bacteria during sugar metabolism. We found that the saliva pH is severely decreased in a mouse m...

Four hundred eighty subjects (mean age 40.73, SE ± 0.33 randomly selected from the municipal electoral registry consented to participate in the survey. Subjects were examined, and the International Caries Detection Assessment System (ICDAS index was registered. A highly structured questionnaire was submitted to investigate (1 personal data (i.e., age, gender, educational level, job categorization, (2 life-style behavior (i.e., smoking and dietary habits, and (3 oral health behavior (i.e., tooth brushing, use of fluoride and dental check-up frequency. An evaluation of the mutans streptococci concentration in saliva was also performed. Information on caries-related factors was entered into the Cariogram in order to generate an individual caries risk profile for each subject. Multinomial logistic regression was performed using Cariogram levels as the dependent variable. The possible correlated variables were analyzed using the principal component analysis (PCA. Considering ICDAS scores, 5.62% of the sample had at least an initial decay (ICDAS = 1-2, whereas 40.83% of the sample presented at least one moderate decay (ICDAS = 3-4 and 17.08% a severe decay (ICDAS = 5-6.

    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.

  12. 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.

    Full Text Available Background: Chemomechanical caries removal system is part of the minimal invasive dentistry; the aim of the study was to compare the amount of bacteria after caries removal with chemomechanical system and conventional rotatory instruments and to test the Vickers microhardness and micro-RAMAN analysis of residual dentin after excavation. Materials and Methods: Molars were induced for demineralization, confirmed with DIAGNOdent; Streptococcus mutans were inoculated into the cavities and filled. Caries removal was performed with rotatory instruments and chemomechanical system; surviving bacteria were cultured for 24 and 48 hours at 37΀C. Vickers microhardness and micro-RAMAN analysis were tested after excavation. Data were analyzed with Wilcoxon, continuity correction, odds ratio, ANOVA post hoc Tukey test, and Spearman correlation. Results: Demineralization was significantly detectable at 240 hours of incubation; conventional rotatory instruments and chemomechanical caries removal were effective in 19.4%-22.6% and 25.8%-32.3%, respectively. Vickers microhardness of chemomechanical system was higher (P < 0.0001 than conventional rotatory instruments and comparable to healthy dentin. Micro-RAMAN analysis showed that healthy dentin is correlated to chemomechanical system (R 2 = 0.683, P < 0.00001 and drilling with burs (R 2 = 0.139, P < 0.00001. Conclusion: The chemomechanical system is effective for caries elimination, comparable to conventional rotatory instruments; the remaining Vickers microhardness and composition surface tissue are similar to healthy dentin.

    2016-01-01

    Background and Objective: In the contemporary scenario of both parents employed, there seems to be limited focus on the dietary habits and dental health of their children. Hence, we attempted to correlate the socioeconomic and working status of the parents to the incidence of their children's dental caries. Materials and Methods: One thousand school children aged between 3 and 12 years were enrolled in the study. Socioeconomic and working status of their parents was obtained by a pretested questionnaire following which these children were examined for their dental caries status. The data collected were statistically analyzed using logistic regression analysis and calculation of odds ratio. Results: A significant correlation was observed between working status of the parents and dental caries status of their children. Though, the socioeconomic status and dental caries had a weak correlation, the odds ratio was high, indicating that the children of lower socioeconomic status or family with both parents employed were at a higher risk for dental caries. Conclusion: Efforts are needed to implement programs at the school level to enhance the oral and dental health among children, as parental responsibilities toward this maybe inadequate due to economic or time constraints.

    Full Text Available Introduction: Globally, non-communicable diseases are increasingly recognized as a major cause of morbidity and mortality. Among them, overweight and obesity are imperative. The problem of overweight and obesity is not confined to adults but also to children and adolescents. The present changing dietary pattern among children is contributing to childhood overweight and on other hand stands as a risk factor in the development of dental caries, hence the study aimed to investigate the relation between overweight and dental caries among school children. Materials and Methods: A cross-sectional study was conducted among 5-6-year and 12-year-old school children to evaluate the relation between body mass index (BMI and dental caries. Using stratified random sampling technique 1017 school children were selected. Subjects who have brought consent from their parents were included and subjects who were absent on the day of examination were excluded. A pre-structured questionnaire was prepared to collect data regarding demographic details, oral hygiene practices, dentition status and treatment needs, (BMI, 24-hour diet history, physical activity, and television watching. The data collected were subjected to statistical analysis (SPSS V 16.0 using Chi-square and multivariate logistic regression tests. Results: "Risk of overweight" 20% and an "overweight" of 40% were observed. With BMI, parental overweight (P = 0.001, socioeconomic status (SES (P = 0.001, physical activity (P = 0.001 and television watching (P = 0.001 were found to be statistically related. Body mass index and dental caries were not statistically related. Conclusion: These complex and multifactorial relations like overweight and dental caries may involve many unknown factors which warrant exploration on larger population.

    Full Text Available This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1 and 40 born term (G2, in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth and DMFT (decayed, missing, and filled permanent teeth. The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95 was found in the group of premature children in comparison to the term children (2.07 p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926. One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

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

    This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

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

    2014-04-01

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

    Full Text Available Objectives: The study examined the hypothesis that severe dental caries may affect growth and development in preschool children. Methods: The study examined 218 children with severe caries using standard diagnostic criteria. All children were weighed and measured and a food frequency questionnaire was completed for each. Six months subsequent to tooth extraction, 131 of the children were followed up and underwent repeat measurement of height, weight, dental health and food intake. For each child, body mass index (BMI was calculated, and all measurements were converted into standard deviation scores and compared to the UK 1990 growth reference. Results: In the six months period after having their decayed teeth extracted the children’s BMIs had increased by 0.654. Two-sided t-tests for paired data showed this difference to be significant (P< 0.01. Conclusion: Treatment of gross dental disease appears to promote "catch-up" growth and normalisation of body mass index.

    Chewable tablets containing low dosage flouride content were prepared using two varities of celluloses and their in vitro parameters were evaluated. An eighteen month clinical trial revealed that both these formulations were effective in controlling the caries. However, ethyl cellulose is proved to be superior to methylcellulose as a controlled release matrix material in controlling caries. Thus this study recommends ethylcellulose matrix tablets containing low flouride content is an efficacious and cost effective drug device in controlling dental caries.

    1999-01-01

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

  2. Role of saliva in caries models.

    Edgar, W M; Higham, S M

    1995-11-01

    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

    2013-06-01

    When prevention of dental caries fails, and a child is exposed to the risk of pain and infection, the disease must be managed to reduce this risk. There is growing evidence supporting more 'biological' and fewer 'surgical' approaches to managing dental caries in primary teeth. These biological methods include partial and stepwise caries removal procedures, as well as techniques where no caries is removed. An overview of clinical trials comparing these biological methods to complete caries removal shows that they perform as well as traditional methods and have the advantage of reducing the incidence of iatrogenic pulpal exposures. The Hall Technique is one biological approach to managing caries in primary molars which involves sealing caries beneath preformed metal (stainless steel) crowns. The crown is cemented over the tooth without caries removal, tooth preparation or use of local anaesthesia. The clinical steps for the Hall Technique are straightforward but, as with all dental care provision, appropriate treatment planning for the procedure requires skill. The Hall Technique offers another method of managing early to moderately advanced, active carious lesions in primary molars, with good evidence of effectiveness and acceptability. This evidence aligns with the positive findings of other studies on biological strategies for managing caries in primary teeth.

  4. Radiographic diagnoses and treatment decisions on approximal caries

    International Nuclear Information System (INIS)

    Mineral loss which represents a threshold value for radiographic diagnosis, cannot be defined exactly. For clinical use 10% mineral loss in the direction of the X-ray beam may constitute a border line lesion for radiographic detection, and caries lesions without cavitation seemed to be beyond this diagnostic threshold. The degree of caries estimated by using radiographs is fairly closely related to the depth of the tissue changes recorded in the prepared cavity. Radiographic examinations more often lead to underestimation than overestimation of the degree of caries. Radiographic caries diagnoses made at different degrees of penetration toward the pulp showed insignificant variations with respect to quality, but the observers were more confident of caries being present (used more strict criterion) when they scored caries in inner dentin. Consensus on diagnostic criteria and improved diagnostic quality are considerably more important to the quality of therapeutic decisions on approximal caries than viewing conditions and film density. A semi-radiopaque material in Class II fillings seems to offer advantages compared to amalgam in respect of the diagnosis of secondary caries and marginal defects. There is a danger that dentists will restore approximal caries lesions too early and before these can be diagnosed in dentin radiographically

    2011-04-01

    Full Text Available Dental caries is a chronic infection disease that manifests itself through demineralization of dental tissues and cavitations in the tooth structure. The diagnosis of dental caries poses challenges due to the complex interaction of multiple endogenous causal factors. Naturally, visual and visual-tactile examinations have been the most commonly used diagnostic aids in caries examination for many years. A major drawback in common dental examination was the use of varied diagnostic criteria by various authors. Some extensive reviews regarding this have emphasized the need for a unique system for the diagnosis of such caries. Thus, International Caries Detection and Assessment System (ICDAS emerged as a benchmark for detection and assessment of dental caries. The main objective of the new system is to improve the level of information to help make informed decision about diagnosis, prognosis, and clinical management of caries at both individual and public health levels.This study aimed to review traditional caries diagnosis methods and also describe the philosophy of the new ICDAS system for diagnosis and assessment of caries and also demonstrate how it can serve as a basis and benchmark for clinical and epidemiological research.

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

    Objective of this article is to appraise diagnostic aspects and treatment modalities in childhood ovarian tumor in background of available evidence. Literature search on Pubmed revealed various aspects of epidemiology, histopathological diagnosis, and treatment of pediatric ovarian tumor. 85 % of childhood tumors are germ cell tumors. The varied histopathological picture in germ cell tumors poses a diagnostic and therapeutic challenge. Immunohistochemistry and newer genetic markers like SALL4 and karyopherin-2 (KPNA2) have been helpful in differentiating ovarian yolk sac tumor from dysgerminoma, teratomas, and other pictures of hepatoid, endometrioid, clear cell carcinomatous, and adenocarcinomatous tissues with varied malignant potential. Before platinum therapy, these tumors were almost fatal in children. Fertility-conserving surgery with bleomycin, etoposide, and cisplatin has dramatically changed the survival rates in these patients. This modality gives cancer cure with healthy offspring to female patients with childhood ovarian tumor. Evidence also supports this protocol resulting in successful pregnancy rates and safety of cytotoxic drugs in children born to these patients. PMID:24757335

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    For many decades, oral health has been improving considerably in France. Caries indicators have decreased strongly. However, some "high risk" populations accumulate the majority of tooth decay. For them, health education and public health policies are inefficient. Tooth decay starts early and continues throughout their lives. Describing dental caries as a chronic pathology enables us to envisage alternative therapies, such as therapeutic patient education.

    Type 1 diabetes mellitus is a chronic metabolic disease of an autoimmune origin with early manifestation predominantly in the childhood. Its incidence has been rising in most European countries. Diabetes has been intensively studied by all branches of medicine. There were a number of studies investigating oral consequences of diabetes; however, unambiguous conclusions were drawn only for the relationship between diabetes and periodontal impairment. Many studies confirmed higher plaque levels and higher incidence of chronic gingivitis both in adults and in children with diabetes. Juvenile periodontitis is rare both in healthy subjects and in those with type 1 diabetes. Yet certain findings from well-conducted studies, for example, differences in oral microflora or the impact of metabolic control of diabetes on periodontal health, indicate a higher risk of periodontitis in children with type 1 diabetes. As for the association of diabetes and dental caries, the results of the studies are inconsistent. However, it was found that some risk factors for dental caries are either more or less prevalent in the diabetic population. Despite an extensive research in this area we have to acknowledge that many questions have remained unanswered. There is a need for continued, thorough research in this area.

    Full Text Available Because of the relationship with subsistence, dental caries is a central issue in paleopathological research. Usually, comparisons between caries prevalence exhibited in different skeletal series are made. Dietary variation is the most common explanation for cavities prevalence. The aim of this paper is to verify if it is possible to compare caries prevalence reported on papers for archaeological skeletal series. Another goal is to determine if other factors besides diet are implicated in dental cavity prevalence explanation. Twenty six papers about dental health with caries prevalences published from 1999 to 2004 were analyzed for completeness. This assessment includes carious lesion diagnosis and characteristics, age, sex and size characteristics of samples, and prevalence calculation method. The majority of the analyzed papers do not provide adequate information in the topics listed above. Only very few implicated factors other than diet as a contributor to caries lesions development.

    To improve sensitivity of dental caries detection by laser-induced breakdown spectroscopy (LIBS) analysis, it is proposed to utilize emission peaks in the ultraviolet. We newly focused on zinc whose emission peaks exist in ultraviolet because zinc exists at high concentration in the outer layer of enamel. It was shown that by using ratios between heights of an emission peak of Zn and that of Ca, the detection sensitivity and stability are largely improved. It was also shown that early caries are differentiated from healthy part by properly setting a threshold in the detected ratios. The proposed caries detection system can be applied to dental laser systems such as ones based on Er:YAG-lasers. When ablating early caries part by laser light, the system notices the dentist that the ablation of caries part is finished. We also show the intensity of emission peaks of zinc decreased with ablation with Er:YAG laser light.

    2014-01-01

    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

    2016-01-01

    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......H always remained above 5.5. Hence, calcium-phosphate-osteopontin particles show potential for applications in caries control....

    Full Text Available OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

    This study aimed to find the set of risk indicators best able to predict root caries (RC) incidence in caries-active adults utilizing data from the Xylitol for Adult Caries Trial (X-ACT). Five logistic regression models were compared with respect to their predictive performance for incident RC using data from placebo-control participants with exposed root surfaces at baseline and from two study centers with ancillary data collection (n = 155). Prediction performance was assessed from baseline variables and after including ancillary variables [smoking, diet, use of removable partial dentures (RPD), toothbrush use, income, education, and dental insurance]. A sensitivity analysis added treatment to the models for both the control and treatment participants (n = 301) to predict RC for the control participants. Forty-nine percent of the control participants had incident RC. The model including the number of follow-up years at risk, the number of root surfaces at risk, RC index, gender, race, age, and smoking resulted in the best prediction performance, having the highest AUC and lowest Brier score. The sensitivity analysis supported the primary analysis and gave slightly better performance summary measures. The set of risk indicators best able to predict RC incidence included an increased number of root surfaces at risk and increased RC index at baseline, followed by white race and nonsmoking, which were strong nonsignificant predictors. Gender, age, and increased number of follow-up years at risk, while included in the model, were also not statistically significant. The inclusion of health, diet, RPD use, toothbrush use, income, education, and dental insurance variables did not improve the prediction performance. PMID:27160516

    The onset of caries is characterized by demineralization of dental hard tissues. Optimal fluoridation with respective oral hygiene habits and diet may stop the progression of a lesion and even allow for its remineralization. The aim of modern dentistry must be a preventive approach rather than invasive repair of the disease. This is possible only with early detection and respective preventive measures. Some of today's diagnostic tools are not sensitive enough to detect this early onset of destruction. Tools based on fluorescence could have the possibility to overcome this problem. This overview will focus on today's knowledge of one possible tool, the DIAGNOdent.

    2015-01-01

    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.

    Full Text Available Ribbond is a biocompatible, esthetic material made from high-strength polyethylene fiber. Lenowoven polyethylene ribbon (Ribbond has been used successfully for tooth splinting, replacement of missing teeth, reinforcement of provisional acrylic resin fixed partial dentures, and orthodontic retention. This article presents the application of this polyethylene ribbon - RIBBOND - for the treatment of nursing bottle caries. To conclude we suggest that this combined technique of polyethylene fibers and composite material could be a very efficient alternative procedure to conventional treatment plans in pedodontic practice, with excellent esthetics and functional results.

    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.

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

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

    The literature has shown that poorer levels of oral health are more frequently related to lower socio-economic status, consequently this cross-sectional and exploratory study conducted in 2003 investigated the association between caries and socio-economic factors, access to care, self-perception and habits among 266 12-year-old schoolchildren living in a community with low prevalence of dental caries. World Health Organization dental caries diagnosis methodology was used, in addition to the application of socio-economic and behavioral questionnaires. To identify the factors associated with dental caries, multivariate logistic regression was used and the dependent variable was synthesized into DMFT=0 and DMFT>0. Bearing in mind the limitations of a cross-sectional study, disliking the appearance of teeth, seeking dental care because of pain, studying at a state school and the head of the family being a manual worker were independently associated with dental caries. Even in a municipality with low prevalence of caries, the socio-economic status, dental care and self-perception were important factors in the incidence of dental caries among schoolchildren, and it is recommended that many factors in the bio-psychosocial context of multi-factorial dental caries should be investigated.

    2016-01-01

    Background: One current strategy for the treatment of carious lesions is the use of biomaterials with antimicrobial activity. Aims: The aim of this study was to evaluate a combination of hydroxyapatite and lysozyme for the treatment of dentinal caries by measuring Streptococcus mutans counts before carious tissue sealing, and 24 h, 1 month, and 6 months after treatment. Materials and Methods: Forty permanent third molars were selected, and flat dentin surfaces were prepared. The teeth were exposed to a cariogenic challenge with S. mutans. After challenge, the dentinal caries were collected from five specimens. The remaining specimens were treated with a mixture of hydroxyapatite and lysozyme in sodium laureth sulfate and sealed with composite resin. S. mutans counts were obtained 24 h, 1 month, and 6 months after sealing. Statistical Analysis: The results were evaluated by descriptive statistics and Wilcoxon signed-rank test. Results: a significant reduction in S. mutans (CFU/mL) was observed in dentinal lesions 1 month after treatment with hydroxyapatite/lysozyme in sodium laureth sulfate (P = 0.0254). Comparison of S. mutans counts obtained 24 h, 1 month, and 6 months after treatment revealed reductions only at the 1-month time point (P = 0.0318). Conclusions: the combination of hydroxyapatite and lysozyme may be an alternative for reducing the S. mutans burden in dentinal caries. PMID:27656068

    2016-01-01

    Background: Low viscosity resin infiltration of initial caries lesions is a modern microinvasive method to treat initial cries lesions. However, only scarce information is available about the long-term surface alterations of infiltrated lesions. Methods: Twenty-eight premolar teeth exhibiting non-cavitated initial caries lesions (International Caries Detection and Assessment System (ICDAS code 1&2)) were divided into two groups, one of which was infiltrated with resin, and the other remained untreated. The teeth underwent two thermocycling procedures. The surface roughness was determined quantitatively, and the results were evaluated statistically. In addition, the surfaces of the lesions were investigated by scanning electron microscopy (SEM), and the surface was analyzed visually with respect to surface irregularities. Results: The results showed a reduction in the surface roughness that was significant after 2500 thermocycles compared to the untreated surface. In the control specimens, no change in the surface roughness was found. The qualitative SEM data also showed a smooth surface after thermocycling, which supported the statistical findings. Conclusion: After thermocycling, resin-infiltrated enamel surfaces become smoother and had no additional risk for plaque accumulation. PMID:27733877

    This study integrates two important developments, the concept of health lifestyles (which has focused on adults and adolescents) and the increased attention to early childhood.

    This study integrates two important developments, the concept of health lifestyles (which has focused on adults and adolescents) and the increased attention to early childhood. We introduce the concept of children's health lifestyles, identifying differences from adult health lifestyles and articulating intergenerational transmission and socialization processes shaping children's health lifestyles. Using the nationally representative Early Childhood Longitudinal Study-Birth Cohort (2001-2007; N ≈ 6,150), latent class analyses identify predominant health lifestyles among U.S. preschoolers. Five distinct empirical patterns representing health lifestyles emerge, two capturing low and medium levels of overall risk across domains and three capturing domain-specific risks. Social background predicts children's health lifestyles, but lower household resources often explain these relationships. Across kindergarten measures of cognition, behavior, and health, preschool health lifestyles predict children's development even after controlling for social disadvantage and concurrent household resources.

    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 Introduction: Dental caries is a multifactorial disease with many contributing factors in the genesis of risk (11. Streptococcus mutans (SM is a gram positive, facultative anaerobe commonly found in the human oral cavity. Described for the first time in 1924 by Clarke, is the main germ responsible for the caries disease (5, 9. In fact, SM produces an insoluble extracellular polysaccharide sucrose which plays an important role as a mediator of the adhesiveness, both as a cementing molecule for other microorganisms, and to create a protected site where the microorganism can proliferate (6, 9, 10. Its presence in the plaque is not equal for all people and is closely related to sugar consumption (9. Its transmission can take place early in the life of the child through the mother’s saliva (2, 3, 4, 8.The early acquisition of this organism is associated with Early Childhood Caries (ECC and then creates a primary colonization which is hardly removed (1, 7. Paying special attention to the health of women and children, this work aimed to decrease the incidence of childhood tooth decay, streamlining preventive efforts in a population at risk. Methods: Since 1999, all women referred to our clinic in the second trimester of pregnancy or during childbirth were offered the opportunity to perform a simple test to measure the presence of SM in saliva and have been given some advice (diet, hygiene, fuoro-prophylaxis, dental visit. The sampling of saliva was performed after chewing one paraffin tablet for about 1 minute. For the microbiological examination the technique of dip-slide test (CTR bacteria, Ivoclar Vivadent was used; results were classified according to semi-quantitative classes of microorganism concentration.Women were classified positive when bacterial concentration was 100000 CFU/ml. Besides a general advice on hygiene and diet, these women were invited to undergo a prophylactic treatment with chlorhexidine, a disinfectant with bactericidal

    Full Text Available Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

    Full Text Available Objective: Verify the prevalence of dental caries and its relationship with the type of feeding, oral hygiene habits, and gender of children at the Cândida Vargas Maternity hospital in João Pessoa, Paraíba, Brazil. Methods: The study population included 50 mentally and physically healthy children ranging from 12 the 48 months of age. This was descriptive study using direct documentation (forms and the clinical examinations performed by one calibrated examiner (Kappa = 1. Dental caries diagnosis was according to World Health Organization criteria. Interviews were conducted with the parents for information about the children’s oral hygiene and dietary habits. Data was analysed by means of descriptive statistics (frequencies and percentages and statistical analyses, using the Pearson Chi – Square and Fisher tests. Results: the prevalence of dental caries was 28%; the majority of the parents cared for the children’s daytime oral hygiene (60%, and the prevalent type of feeding was with powdered milk. The average dmf-t was 0.28 and 16% of children had early childhood caries. There was no statistically significant association with any of the variables studied.Conclusion: the prevalence of caries–free children was high. However, the poor oral hygiene after nocturnal breast-feeding and the early introduction of artificial milk, especially with bottle feeding suggests the need to reinforce educational strategies for the parents.

    2015-07-01

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

    Full Text Available Background and Aim: An important purpose of adhesive dentistry is restriction of cavity preparation to carious dentin removal and conservation of sound dentin. Application of caries disclosing agents and cavity disinfectants can help achieving this goal. The aim of this study was to evaluate the effect of caries disclosing agents and cavity disinfectants on microleakage of composite resin restorations. Materials and Methods: This experimental in-vitro study was performed on class V cavities in 48 extracted human sound premolars. The teeth were randomly divided into four equal groups. In group 1 caries detector dye (Seek, Ultradent, USA and in group 2 cavity disinfectant (Consepsis, Ultradent, USA were applied on dentinal surfaces. In group 3 both mentioned materials were applied. Group 4 was considered as control group. PQ1 bonding agent and Amelogen composite were used to restore the cavities. Gingival microleakage was assessed by dye penetration. Data were analyzed by Kruskall Wallis and Dunn tests. P<0.05 was the level of significance.Results: Group 2 showed the least and group 4 showed the highest microleakage;however no statistical significant difference was found among the groups.Conclusion: The use of caries disclosing agent (Seek and cavity disinfectant (Consepsis Liquid did not adversely affect the sealing ability of dentin bonding resins.

    The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restorations in their first dental appointment. The dependent variable was the time of occurrence of new dental caries or restorations and was measured in months. Gender, age, International Code of Diseases (ICD), mother´s education, sugar consumption, use of fluoride toothpaste, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic or asthma drugs, and history of asthma were covariates. The Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental caries/restoration was equal to 107.46 months (95%CI 95.41 to 119.51), with a median of caries-free children up to 94 months. For each point increase in the scale of sucrose consumption, the increase in caries risk was 1.07 (95%CI 1.01 to 1.15). Sucrose consumption was the only risk factor for dental caries found in this group of individuals with developmental disabilities. PMID:27305514

  1. Low levels of caries in aggressive periodontitis: A literature review

    Directory of Open Access Journals (Sweden)

    Sulugodu Ramachandra Srinivas

    2014-04-01

    Full Text Available This article is a traditional literature review on caries levels in aggressive periodontitis. Aggressive periodontitis generally affects systemically healthy individuals aged <30 years (older individuals can also be affected and is characterized by a young age of onset, rapid rate of disease progression, and familial aggregation of cases. Dental caries is caused by the dissolution of enamel by acid-producing bacteria present in the plaque biofilm, especially when the biofilm reaches critical mass due to improper oral hygiene. The association between caries level and aggressive periodontitis has long been debated. Initial research indicated that caries levels were high in patients with aggressive periodontitis, but high-quality studies have consistently shown that caries and aggressive periodontitis are inversely related. A recent in vitro study showed that Streptococcus mutans was killed more readily in the saliva of patients with aggressive periodontitis and Aggregatibacter actinomycetemcomitans positivity than in patients with A. actinomycetemcomitans negativity. Other mechanisms possibly explaining the inverse relationship between caries and aggressive periodontitis in cases of Down’s syndrome are also discussed in this literature review. The usefulness of caries level in the diagnosis of aggressive periodontitis in developing countries such as India, where the disease is diagnosed primarily on the basis of clinical and radiographic features and familial history is also discussed.

    Full Text Available The accuracy in pits and fissures caries detection is of paramount importance in dental caries primary and secondary prevention. A combination of visual examination and probing is currently the mainstay of occlusal caries diagnosis. Unfortunately, these types of inspection alone may leave a certain number of pit and fissure caries undetected. The Vista Cam iX fluorescence camera (Durr Dental, Bietigheim-Bissingen, Germany is a novel dental diagnostic tool for quantitative assessment of dental caries with high specificity for carious lesions detection. In the presented cases photographic images, representing the visual diagnostic approach, are applied as integration to VistaCam iX Proof images. A step-by-step sequence of inspection and assessment of operative treatment need is presented in a case of hidden pit and fissure caries on a permanent molar. Based on the reported case, it could be observed that VistaCam iX Proof shows promising results in hidden pits and fissures caries detection and could be considered a non-invasive examination method that facilitate the detection of early lesions and a potential diagnostic aid.

    Psoriasis is a common skin disease in infants, children, and adolescents. A review of the clinical, epidemiologic, genetic, and therapeutic aspects of childhood psoriasis is presented. Population studies indicate that the first signs of psoriatic lesions occur in the pediatric age group, birth to 18 years of age, and that both genetic and environmental factors interact to precipitate the development of psoriasis. Koebner reactions are the result of external or internal triggering factors, such as physical injury to the skin, low humidity, and certain drugs. The most frequently observed variant to psoriasis is the plaque type, followed by guttate psoriasis, and juvenile psoriatic arthritis. Pustular psoriasis and erythrodermic psoriasis are rare forms of the disease, but are seen in children from infancy to adolescence. The scalp is the most frequently affected site of involvement in pediatric psoriasis, followed by the appearance of lesions on the extensor surfaces of the extremities, trunk, and nails. Although not common in adult psoriasis, the face and ears are often involved. Topical medications such as corticosteroids, calcipotriol, coal tar preparations, anthralin formulations, and ultraviolet B are recommended in monotherapy or in combination therapy, whereas psoralen plus ultraviolet A, methotrexate, and retinoids should only be administered in crisis situations. The treatment objectives in childhood psoriasis are to preserve skin surfaces, to afford physical relief from the disease, and to employ treatments that do not endanger the health or future development of the child.

    Vitamin D is an essential hormone for calcium gut absorption. It is also involved in child growth, cancer prevention, immune system responses, and tooth formation. Due to inadequate vitamin D intake and/or decreased sunlight exposure, vitamin D deficiency has resurfaced in developed countries despite known inexpensive and effective preventive methods. Vitamin D deficiency is a common cause of rickets, a condition that affects bone development in children and that can have serious dental complications. Deficiency during pregnancy can cause enamel hypoplasia of primary teeth. Enamel regeneration is currently impossible; hypoplasia is therefore irreversible, and once affected, teeth are prone to fast caries development. Deficiency during early childhood can affect permanent teeth and ensuing caries can sometimes lead to tooth loss at a young age. Oral manifestations of rickets should be diagnosed early by both physicians and dentists to prevent severe dental complications. This case study presents 2 young girls with rickets in early childhood who suffered from subsequent serious tooth decay.

    Full Text Available Abstract Background Dental caries is the result of a complex interplay of multiple determinants which may change overtime. Therefore, periodic surveys of caries experience and redetermination of the risk indicators of the disease are needed. The aim of this study was to assess the prevalence and severity of coronal and root caries in Greeks aged 35-44 and 65-74-year-old in relation to socio-demographic parameters. Furthermore, trends in coronal caries experience of the 35-44-year-olds were investigated. Methods A sample of 1188 35-44-year-old and 1093 65-74-year-old individuals was selected in 2005 according to WHO guidelines for national pathfinder surveys. Caries was assessed in dentate subjects using the DMFT, DMFS, RDFS and RCI indices. Socio-demographic data were also collected. Univariate and multivariate regression analyses were performed to identify the effect of socio-demographic parameters. Results The mean DMFT and DMFS scores of the adults were 14.06 and 45.78 respectively, while those of the senior citizens were 20.63 and 89.82. Among the 35-44-year-ods, men and those having a higher educational attainment had significantly lower DMFS values (women OR = 1.679, CI: 1.243-2.267 and >12 years of education OR = 0.321, CI: 0.193-0.535 respectively, while educational level was the only predictor of DMFS in senior citizens (OR = 0.279, CI: 0.079-0.992. The mean DMFT score of the 35-44-year-olds has not improved since 1985, but there was a remarkable reduction in the number of DT related to a simultaneous increase in the number of FT. The mean RDFS rose from 0.39 in adults to 2.66 in senior citizens. The mean RDFS score of the middle aged adults was significantly correlated with education (OR = 0.346, CI: 0.180-0.664.

A non-invasive concept for prevention and management is emerging based...... on the common risk factor approach. There is strong evidence that tooth brushing twice a day with fluoridated toothpaste is the most cost-effective way to prevent and control caries development. Physicians need to consider that a number of drugs may affect the saliva flow rate, which increases the caries risk....

    Ozone, either in gaseous form or as ozonated water, has been available for use as a treatment for dental caries for a decade. This paper reviews the literature on the subject by examining the findings of publications in the peer review literature. Eighteen papers were identified by a literature search. From the review of these, it was concluded that, while some laboratory studies and some short duration clinical studies have suggested that ozone may be effective in the treatment of root caries or killing of oral micro-organisms, the clinical evidence for the use of ozone in treatment of caries is not compelling.

Familiarity with the pattern of this type of caries and evaluation of its symmetrical or asymmetrical pattern is necessary for effective and scientific diagnosis and treatment. The aim was to assess the symmetrical or asymmetrical aspects of Nursing Caries in children between3-5 years old.Materials and Methods: In this cross-sectional study, 10 kindergartens were randomly selected by the TehranWelfare Organization. 115 children with NC caries entered to study after examination. Written consents were obtained from the parents. The dmfs in upper primary incisors and upper and lower primary canines, as well as the first primary molars were assessed and the caries pattern in terms of symmetrical or asymmetrical aspects wasevaluated. The data were analyzed by ANOVA, LSD, Chi-square and Fisher tests.Results: In 53.9% of the children with NC, the anterior teeth were affected symmetrically, while 46.1% indicated an asymmetrical pattern. In general, 32.2% of the teeth were affected in a symmetrical pattern and 67.8% of them in an asymmetrical pattern. About the relationship between the breastfeeding from the right or left breast and the symmetrical pattern of the NC, 51% of the children were equally breastfed from both breasts. However, in the asymmetrical NC pattern with more impact in the right side of dentition, 50% of the children had been breastfed from the left side and in children with more caries in the left side of dentition, 50% of them had been breastfed rom the right side (P=0.01.Conclusion: NC has symmetrical and asymmetrical patterns. Direction of mother for breastfeeding affects the symmetrical and asymmetrical pattern of NC.

    A possible consequence of light absorption as the interaction of electromagnetic radiation with molecules of the tooth's hard substances is, apart from the emission of heat, fluorescence. It was demonstrated that the emission spectra of enamel, dentin, and caries look alike upon excitation with red light; however, fluorescence increases with the process of carious destruction. Based on that, the DIAGNOdent System was developed, which simultaneously injects red light into the tooth surface and detects the resulting fluorescence. Due to this design, clinical application is currently limited to accessible occlusal and smooth surfaces. For occlusal caries detection, it was shown that validity and reproducibility could be optimized over classical diagnostic tests for deep dentin lesions with seemingly intact surfaces. The detection of root caries does not play a relevant role in the directly accessible areas, but estimation of the lesion's activity and progression rate is a prerequisite for differentiated lesion management Excellent reproducibility of the laser fluorescence measurements was confirmed for this scenario. Lesions with a soft surface texture show significantly higher fluorescence values than leathery or hard lesions, and values also increase with increasing cavity depth. DIAGNOdent offers the potential to improve follow-ups and estimation of the prognosis and to support clinical management of primary carious lesions.

    Ma, M S; Blanksma, N G

    2015-01-01

    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

    This study evaluated the caries inhibition of dentin primers with the addition of fluoride. Two standardized Class V preparations were placed in 20 molars, the gingival margin placed below the cementoenamel junction and the occlusal margin placed in enamel. Two dentin primers (Syntac and ScotchPrep) were placed in equal numbers of 20 preparations, according to manufacturer's instructions. Ammonium fluoride (10% by weight) was then added to these primers and they were placed in the remaining 20 preparations, opposing the non-fluoridated primer of the same system. All teeth were then restored with a non-fluoridated resin composite. All teeth were subjected to an artificial caries challenge (pH 4.2) for 5 days. Sections of 100 microns were obtained, photographed under polarized light microscopy, then demineralized areas were quantitated by digitization. Results demonstrated the mean areas (mm2 +/- S.D.) demineralization at 0.25 mm, 0.5 mm and 1.0 mm from the restoration margin to be: Syntac/fluoride (1.44 +/- 0.49, 1.68 +/- 0.54, 3.72 +/- 0.74); Syntac (1.99 +/- 0.58, 1.50 +/- 0.35, 2.98 +/- 1.26); ScotchPrep/fluoride (1.23 +/- 0.68, 1.55 +/- 0.64, 3.08 +/- 1.16); ScotchPrep (1.90 +/- 0.83, 1.71 +/- .038, 3.36 +/- 0.62). A paired t-test indicated primers with fluoride to demonstrate significantly less demineralization 0.25 mm from the restoration margin (P < 0.07). PMID:7880460

  4. Elevated incidence of dental caries in a mouse model of cystic fibrosis.

    Directory of Open Access Journals (Sweden)

    Marcelo A Catalán

    Full Text Available BACKGROUND: Dental caries is the single most prevalent and costly infectious disease worldwide, affecting more than 90% of the population in the U.S. The development of dental cavities requires the colonization of the tooth surface by acid-producing bacteria, such as Streptococcus mutans. Saliva bicarbonate constitutes the main buffering system which neutralizes the pH fall generated by the plaque bacteria during sugar metabolism. We found that the saliva pH is severely decreased in a mouse model of cystic fibrosis disease (CF. Given the close relationship between pH and caries development, we hypothesized that caries incidence might be elevated in the mouse CF model. METHODOLOGY/PRINCIPAL FINDINGS: We induced carious lesions in CF and wildtype mice by infecting their oral cavity with S. mutans, a well-studied cariogenic bacterium. After infection, the mice were fed a high-sucrose diet for 5 weeks (diet 2000. The mice were then euthanized and their jaws removed for caries scoring and bacterial counting. A dramatic increase in caries and severity of lesions scores were apparent in CF mice compared to their wildtype littermates. The elevated incidence of carious lesions correlated with a striking increase in the S. mutans viable population in dental plaque (20-fold increase in CF vs. wildtype mice; p value < 0.003; t test. We also found that the pilocarpine-stimulated saliva bicarbonate concentration was significantly reduced in CF mice (16 ± 2 mM vs. 31 ± 2 mM, CF and wildtype mice, respectively; p value < 0.01; t test. CONCLUSIONS/SIGNIFICANCE: Considering that bicarbonate is the most important pH buffering system in saliva, and the adherence and survival of aciduric bacteria such as S. mutans are enhanced at low pH values, we speculate that the decrease in the bicarbonate content and pH buffering of the saliva is at least partially responsible for the increased severity of lesions observed in the CF mouse.

    ABSTRACT Background: Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life. Aim: To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city. Study design: This study was of cross-sectional design. Materials and methods: The study group comprised 512 preschool children 2-6 years of age. The prevalence of caries was recorded using "Dentition status and treatment needs" (WHO basic oral health assessment form, 1997). They were divided into three groups as follows: Group I (dmft score = 0-2), group II (dmft score = 3-4) and group III (dmft score ≥5). The handprints of each child were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and were classified according to the topological method. The frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Statistics: Chi-square test was used to test the significant difference in proportions. Means were compared using Student’s t-test and analysis of variance (ANOVA) or F-test. Results: Subjects belonging to groups II and III showed maximum occurrence of whorl pattern on all digits. Group I subjects had maximum occurrence of arch pattern. All the variables had statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among all three groups. Conclusion: The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of arch pattern.

    Background Currently, several systems of dentin substrate-reacting adhesives are available for use in the restorative treatment against caries. However, the bond effectiveness and property of different adhesive systems to caries-affected dentin are not fully understood. The objective of this study was to evaluate the bond strength of different adhesives to both normal dentin (ND) and caries-affected dentin (CAD) and to analyze the dentin/adhesive interracial characteristics.Methods Twenty eight extracted human molars with coronal medium carious lesions were randomly assigned to four groups according to adhesives used. ND and CAD were bonded with etch-and-rinse adhesive Adper~(TM) Single Bond 2 (SB2) or self-etching adhesives Clearfil SE Bond (CSE), Clearfil S~3 Bond (CS3), iBond GI (IB). Rectangular sticks of resin-dentin bonded interfaces 0.9 mm~2 were obtained. The specimens were subjected to microtensile bond strength (μTBS) testing at a crosshead speed of 1 mm/min. Mean μTBS was statistically analyzed with analysis of variance (ANOVA) and Student-Newman-Keuls tests. Interfacial morphologies were analyzed by Scanning Electron Microscopy (SEM).Results Etch-and-rinse adhesive Adper~(TM) Single Bond 2 yielded high bond strength when applied to both normal and caries-affected dentin. The two-step self-etching adhesive Clearfil SE Bond generated the highest bond strength to ND among all adhesives tested but a significantly reduced strength when applied to CAD. For the one-step self-etching adhesives, Clearfil S~3 Bond and iBond GI, the bond strength was relatively low regardless of the dentin type. SEM interfacial analysis revealed that hybrid layers were thicker with poorer resin tag formation and less resin-filled lateral branches in the CAD than in the ND for all the adhesives tested.Conclusion The etch-and-rinse adhesive performed more effectively to caries-affected dentin than the self-etching adhesives.

    The purpose of this study was to obtain information about the detailed histopathology of naturally occurring root caries. Fifty extracted human teeth exhibiting some degree of root caries were sectioned longitudinally and examined with transmitted light, polarized light and microradiography. The occurrence of the histological zones of dentinal caries was tabulated and revealed a lesion body in all cases. Light microscopy showed the same basic features as microradiography and was most useful when the sections were imbibed in quinoline. A structureless area below the main body of the lesion was observed in 77% of the cases when using quinoline. This fluid more clearly defined the extent of the lesion and may show a "phenolic reaction" when using polarized light microscopy. Partial radiopaque surface layers were observed in almost 80% of the sections. This study has described the detailed histopathology of root caries, and aids in the development of model systems to evaluate this emerging dental health problem. PMID:3930671

    2010-07-01

    This article reviews the current methods for detection and assessment of caries lesions focusing on applicability for daily clinical practice. The end point is to arrive at a diagnosis for each caries lesion. Visual inspection aided by a ball-ended probe is essential for caries lesions assessment and the method must be used for all patients. Use of indices, for example, the International Caries Detection and Assessment System (ICDAS), can improve the performance of this method. Using visual inspection, the clinician must decide about the presence, severity and activity of lesions. After this process, additional methods could aid the dentist in reaching a more appropriate treatment decision in some cases. The ICDAS, including the activity assessment system or the Nyvad system, seems to be the best option to reach final diagnoses for managing lesions. The radiographic method is the most recommended additional method available for daily clinical practice.

    2016-03-01

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

    Full Text Available Background: The incidence of dental caries with periapical granulomas in Indonesia is quite high. However, the mechanism of the formation of periapical granulomas in dental caries caused by bacterial infection in immunopathobiogenesis cannot be explained completely. Thus, this explanation is necessary in order to be used as a basis for diagnostic, preventive and therapeutic measures. Purpose: This research was aimed to determine the role of Hsp60, CD-8 and IFN-γ in immunopatobiogenesis of periapical granuloma in dental caries. Methods: This research was an analytic observational study with cross sectional approach. Samples of this research were 36 teeth of patients with dental caries, consisting of 18 caries teeth with periapical granulomas and 18 caries teeth without periapical granulomas. The variables observed in this research were Hsp60, CD-8 and IFN-γ. Measurements were conducted by using immunohistochemical methods on periapical tissue. Results: The mean of Hsp60, CD-8 and IFN-γ in granuloma group was significantly higher than those in non granuloma group (p<0.05. The positive role of IFN-γ on the incidence of granulomas appeared to be more prominent. Conclusion: The study suggested that in immunopathobiogenesis of periapical granuloma in dental caries, Hsp60, CD-8 and IFN-γ played important roles, but the role of IFN-γ was found to be more prominent.Latar belakang: Angka kejadian gigi karies dengan granuloma periapikal di Indonesia cukup tinggi, Namun mekanisme terbentuknya granuloma periapikal pada gigi karies yang disebabkan oleh infeksi bakteri secara imunopatobiogenesis belum dapat dijelaskan secara tuntas.

    The morphological complexity of the occlusal surface of deciduous molar teeth is considered as a factor to increase vulnerability to caries lesion. Occlusal surface of these teeth shows sulcus, pits and fissures which allow retention of both micro-organisms and food debris which make them more susceptible to caries. In the last decades there was a significant reduction on caries of smooth surface but not on the occlusal surface where dentinal caries develops under fissures which are apparently caries-free under eye observation. This is known as a hidden caries. The occlusal surface of sound extracted deciduous molar teeth were examined using a 655 nm diode laser (DIAGNOdent - KaVo) in order to detect hidden caries. When there was indication of a hidden caries, the area was examined using SEM and confirm or not the diagnosis. The authors concludes that the diagnosis of caries using 655 diode laser is reliable and precise method.

    Arginine metabolism by oral bacteria via the arginine deiminase system (ADS) increases the local pH, which can neutralize the effects of acidification from sugar metabolism and reduce the cariogenicity of oral biofilms. To explore the relationship between oral arginine metabolism and dental caries experience in children, we measured ADS activity in oral samples from 100 children and correlated it with their caries status and type of dentition. Supragingival dental plaque was collected from tooth surfaces that were caries-lesion-free (PF) and from dentinal (PD) and enamel (PE) caries lesions. Regardless of children's caries status or type of dentition, PF (378.6) had significantly higher ADS activity compared with PD (208.4; p caries status. Mixed-model analysis showed that plaque caries status is significantly associated with ADS activity despite children's age, caries status, and dentition (p caries.

    Most of the caries of African child populations is found in limited fractions of that population. The purpose of the present study was to analyze the caries situation of Sierra Leonean schoolchildren in relation to demographic, socioeconomic, and behavioral variables, in order to develop an appropriate index for prediction of caries. A total of 610 students from primary class 1 (mean age: 7 yr) and secondary form 1 (mean age 15 yr) were dentally examined by three examiners and interviewed by their teachers. Intra- and interexaminer reproducibilities were 82 and 70%, and interinterviewer reliability was 67-100% for the individual questions. Urban students had more caries than rural. In class 1, dmfs+DMFS was 4.1 and 1.8, respectively; in form 1, DMFS was 5.3 and 3.5. Two tribes (the Fulas and the Madingos) had higher caries means than the rest, especially in class 1, where dmfs+DMFS was 6.5 and 2.4, respectively. Form 1 students with literate parents had a higher caries mean, and class 1 pupils with defective school uniforms a lower mean. The apparently high-risk groups did not consume more sweet snacks or clean their teeth less frequently. There was clearly more caries among the quartiles of children with most visible plaque on molars, but all social and demographic subgroups had similar amounts of plaque. Multivariate analyses of class 1 children showed that pupils living in urban areas, Fulas and Madingos, and children wearing complete school uniforms had caries significantly more frequently, other factors being equal.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8322004

    The use of fluoride, frequent brushing and flossing, regular dental examinations, and limiting the ingestion of sweet snacks between meals are of primary importance in preventing dental caries. Because many commonly used medications have high concentrations of sucrose, the child with a chronic illness who needs medication on a long-term basis is at higher risk both for caries formation and for compliations of tooth decay. To minimize this risk most medication should be considered equivalent t...

    Background Worldwide, the public health community has recognized the growing problem of childhood obesity. But, unlike tobacco control policy, there is little evidence about what public policies would work to substantially reduce childhood obesity. Public health leaders currently tend to support traditional "command and control" schemes that order private enterprises and governments to stop or start doing specific things that, is it hoped, will yield lower childhood obesity rates. These inclu...

    Investigations into the oral health status of indigenous populations are scarce. The aim of this study was to evaluate caries experience and associated factors among 342 indigenous children and adolescents aged 5-15 years of the Xukuru community in the municipality of Pesqueira, Brazil. A cross-sectional census study was carried out using the criteria of the World Health Organization to determine caries experience. Examinations were performed by two calibrated dentists and a questionnaire was administered to parents/caregivers addressing socio-demographic data, diet and oral hygiene habits. Logistic regression analysis were performed, with dmft and DMFT as the dependent variables (P Caries experience (dmft/DMFT) was high in both the primary and permanent dentition (75.6% and 62.9%, respectively). Mean dmft and DMFT indices were 3.11 and 2.21, respectively. Caries experience in the primary dentition was associated with children residing in villages far from urban areas (P = 0.016), while caries in the permanent dentition was associated with older children (P caries experience, which was associated with age and group of villages. Public policies are needed to improve the oral health status of this population. PMID:26062861

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. Keywords: xylitol, caries preventive effect, oral flora

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

    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.

    The aim of this study was to analyze the relationship between current dietary habits and dental caries in schoolchildren from an area of Spain on which the prevalence of caries was low. The results of an epidemiological study conducted on a random sample of 893 children from the cities of Girona and Figueres are presented. The method of dietary interview consisted of a food-frequency questionnaire. This showed a positive relationship between dental caries and consumption of ice cream, pastries, cakes, sliced bread, on the one hand, and sugar-free chewing gum and sugar-free candies, on the other. A protective effect of skimmed milk and artificial sweeteners was also observed. Results reflect the role of certain foods in caries development, but also the outcome of selective dietary counseling to high-risk children. PMID:8281564

    Background Since the 2008 inception of universal childhood influenza vaccination, national rates have risen more dramatically among younger children than older children and reported rates across racial/ethnic groups are inconsistent. Interventions may be needed to address age and racial disparities to achieve the recommended childhood influenza vaccination target of 70%. Purpose To evaluate an intervention to increase childhood influenza vaccination across age and racial groups. Methods In 2011–2012, 20 primary care practices treating children were randomly assigned to Intervention and Control arms of a cluster randomized controlled trial to increase childhood influenza vaccination uptake using a toolkit and other strategies including early delivery of donated vaccine, in-service staff meetings, and publicity. Results The average vaccination differences from pre-intervention to the intervention year were significantly larger in the Intervention arm (n=10 practices) than the Control arm (n=10 practices), for children aged 2–8 years (10.2 percentage points (pct pts) Intervention vs 3.6 pct pts Control) and 9–18 years (11.1 pct pts Intervention vs 4.3 pct pts Control, p<0.05), for non-white children (16.7 pct pts Intervention vs 4.6 pct pts Control, p<0.001), and overall (9.9 pct pts Intervention vs 4.2 pct pts Control, p<0.01). In multi-level modeling that accounted for person- and practice-level variables and the interactions among age, race and intervention, the likelihood of vaccination increased with younger age group (6–23 months), white race, commercial insurance, the practice’s pre-intervention vaccination rate, and being in the Intervention arm. Estimates of the interaction terms indicated that the intervention increased the likelihood of vaccination for non-white children in all age groups and white children aged 9–18 years. Conclusions A multi-strategy intervention that includes a practice improvement toolkit can significantly improve influenza

    Medulloblastoma accounts for 15-20% of childhood nervous system tumours. The risk of dying was reduced by 30% in the last twenty years. Patients are divided in risk strata according to post-surgical disease, dissemination, histology and some molecular features such as WNT subgroup and MYC status. Sixty to 70% of patients older than 3 years are assigned to the average-risk group. High-risk patients include those with disseminated and/or residual disease, large cell and/or anaplastic histotypes, MYC genes amplification. Current and currently planned clinical trials will: (1) evaluate the feasibility of reducing both the dose of craniospinal irradiation and the volume of the posterior fossa radiotherapy (RT) for those patients at low biologic risk, commonly identified as those having a medulloblastoma of the WNT subgroup; (2) determine whether intensification of chemotherapy (CT) or irradiation can improve outcome in patients with high-risk disease; (3) find target therapies allowing tailored therapies especially for relapsing patients and those with higher biological risk.

    In many odontological studies concerning archeological material, there is no analysis of early caries lesions (caries incipiens) that manifest as a carious spot. At this stage of caries, the enamel is still hard, and thus, it is impossible to diagnose caries by visual methods. We assessed the usefulness of the DIAGNODent pen (DD laser) in analyzing noncavity lesions on the smooth surface sites of crowns from historical populations. Twenty-seven individuals were examined: 18 from Radom (Poland), and nine from Tell Masaikh and Terqa (Syria). A total of 562 teeth were characterized. The series represented different climatic zones, but were dated from the similar period, 18th to 19th century AD. We used four diagnostic techniques: visual, DD laser, radiographic, and histological as the gold standard. DD laser showed that the mean values of healthy enamel in both series did not exceed 15 units. The mean values of smooth and rough spots in the Syrian population were significantly higher than those from Poland. This study showed that all the noncarious spots from the Radom series did not exceed 30 units. In the Syrian samples, this limit was higher at 44 units. These results were confirmed by histology and radiography. The DD laser provided good results in detecting dentine carious lesions in historical material, but its efficiency in diagnosing early caries (caries incipiens) remains uncertain based on the presented series.

    Dental caries is a multifactorial disease that can be conceptualized as an interaction between genetic and environmental risk factors. The aim of this study is to examine the effects of AMELX, CA6, DEFB1, and TAS2R38 gene polymorphism and gene-environment interactions on caries etiology and susceptibility in adults. Genomic DNA was extracted from the buccal mucosa, and adults aged 20 to 60 y were placed into 1 of 2 groups: low caries risk (DMFT ≤ 5; n = 77) and high caries risk (DMFT ≥ 14; n = 77). The frequency of AMELX (+522), CA6 (T55M), DEFB1 (G-20A), and TAS2R38 (A49P) single-nucleotide polymorphisms was genotyped with the polymerase chain reaction-restriction fragment length polymorphism method. Environmental risk factors examined in the study included plaque amount, toothbrushing frequency, dietary intake between meals, saliva secretion rate, saliva buffer capacity, mutans streptococci counts, and lactobacilli counts. There was no difference between the caries risk groups in relation to AMELX (+522) polymorphism (χ(2) test, P > 0.05). The distribution of CA6 genotype and allele frequencies in the low caries risk group did not differ from the high caries risk group (χ(2) test, P > 0.05). Polymorphism of DEFB1 (G-20A) was positively associated, and TAS2R38 (A49P) negatively associated, with caries risk (χ(2) test, P = 0.000). There were significant differences between caries susceptibility and each environmental risk factor, except for the saliva secretion rate (Mann-Whitney U test, P = 0.000). Based on stepwise multiple linear regression analyses, dental plaque amount, lactobacilli count, age, and saliva buffer capacity, as well as DEFB1 (G-20A), TAS2R38 (A49P), and CA6 (T55M) gene polymorphism, explained a total of 87.8% of the variations in DMFT scores. It can be concluded that variation in CA6 (T55M), DEFB1 (G-20A), and TAS2R38 (A49P) may be associated with caries experience in Turkish adults with a high level of dental plaque, lactobacilli count

Secondly, to explore the factors associated with higher caries prevalence in those with the highest DMFT scores compared to the caries-free group. Methods Over 4000 adolescents between ages 12 and 19 (Case Group: N = 2124; Control Group: N = 2045 received oral health screenings conducted in public/private middle and high schools in Nevada in 2008/2009 academic year. Caries prevalence was computed (Untreated decay scores [D-Score] and DMFT scores for the 30% of Nevada Youth who presented with the highest DMFT score (case group and compared to the control group (caries-free and to national averages. Bivariate and multivariate logistic regression was used to analyze the relationship between selected variables and caries prevalence. Results A majority of the sample was non-Hispanic (62%, non-smokers (80%, and had dental insurance (70%. With the exception of gender, significant differences in mean D-scores were found in seven of the eight variables. All variables produced significant differences between the case and control groups in mean DMFT Scores. With the exception of smoking status, there were significant differences in seven of the eight variables in the bivariate logistic regression. All of the independent variables remained in the multivariate logistic regression model contributing significantly to over 40% of the variation in the increased DMFT status. The strongest predictors for the high DMFT status were racial background, age, fluoridated community, and applied sealants respectively. Gender, second hand smoke, insurance status, and tobacco use were significant, but to a lesser extent. Conclusions Findings from this study will aid in creating educational programs and other primary and secondary interventions to

    The Electronic Caries Monitor (ECM) and the recently introduced laser-based KaVo DIAGNOdent have been developed as clinical diagnostic aids in the detection and quantification of occlusal carious lesions. The aim of this in vitro study was to compare their reproducibility and validity. The ability of DIAGNOdent to retrieve sites of occlusal carious lesions without reference to photographs or drawings from previous assessments was also tested. The material comprised 87 premolar teeth: the occlusal surfaces were sound or exhibited non-cavity carious lesions of varying severity. All were photographed and measured by DIAGNOdent and ECM on 2 occasions, 2 weeks apart. The teeth were then sectioned into 300 microm thick slices. Two observers independently classified the sections according to the histopathology, into 5 categories, ranging from sound to dentinal caries in the inner part of the dentin. Statistical analysis comprised intra-class correlation coefficients (ICC) to test reproducibility and regression analysis of validity. Sensitivity and specificity were also calculated for detection of D3 lesions for both devices. DIAGNOdent recorded maximum readings at identical sites on both occasions in 89% of the teeth. The ICC for readings on 2 separate occasions was 0.97 for DIAGNOdent and 0.71 for ECM. The correlations with histology were r = 0.93 and 0.83, for DIAGNOdent and ECM, respectively. For detection of D3 lesions, the sensitivity and specificity were 0.8 and 1 for DIAGNOdent and 0.75 and 0.88 for ECM. In this in vitro study, DIAGNOdent was superior to ECM for occlusal caries detection.
