Dental caries is one of the most common infectious diseases affecting 6–8-year-old children, especially their first permanent molars (FPMs). This study explored the prevalence of dental caries on FPMs by analyzing the oral health status of 1,423,720 children aged 6–8 years in Zhejiang Province, China. The data were extracted from the dental electronic records of the schoolchildren attending the Oral Health Promotion Project (OHPP), conducted during 2013–2017 in Zhejiang Province. Multiple logistic regression models were used to determine the factors affecting dental caries. Boys and girls accounted for 53.2% and 46.8% of the subjects, respectively. From 2013 to 2017, the prevalence of dental caries on FPMs increased: 2013: 20.4%; 2014: 25.3%; 2015: 24.5%; 2016: 27.0%; and 2017: 29.0%, despite the OHPP conducted. Based on multiple logistic regression model, girls had a significantly higher risk of FPM caries compared to boys (OR = 1.38, 95% CI: 1.37–1.39, p < 0.0001); compared with the caries rates in urban areas, the caries risk was significantly higher in rural areas (OR = 1.15, 95% CI: 1.14–1.16, p < 0.0001). In terms of geographic location in Zhejiang Province, the odds ratios of the caries risk of the east, south, west, and north were 1.35 (1.33–1.36), 1.3 (1.28–1.31), 0.81 (0.8–0.83), and 0.82 (0.81–0.84), respectively (p < 0.0001), by considering the central region as a reference. The caries prevalence of FPMs was high, with an increasing tendency and gender, social, cultural, and environmental factors affecting the caries prevalence.

Background From 2005 to 2015, the prevalence of dental caries in both primary and permanent dentitions was significantly increased in China. Previous studies have shown that the prevalence of permanent dental caries in school-aged children had already reached 19.7%–54.0%, 97.5% affecting first permanent molars. This study aimed to investigate the prevalence and contributing factors of dental caries in 6-year-old children in four regions of China to provide information for oral health promotion programs. Methods A randomized cluster sampling method was employed in the study. All 6-year-old first grade children from the selected schools were invited to receive a clinical oral examination. Dental caries were diagnosed according to the World Health Organization criteria. The erupting first permanent molars were recorded using the modified International Caries Detection Assessment System. Questionnaires assessing children’s oral health-related behaviors and their caretakers’ oral health awareness and attitudes were completed by the children’s parents or guardians. Results Overall, 4,936 6-year-old school children participated in the survey. The prevalence of caries among these children was 87.7%, with a mean number of decayed, missing and filled teeth of 6.04 (SD, 4.24). In primary dentition, the caries prevalence was 87.7%, and the mean dmft score was 6.01 (SD, 4.22). In permanent dentition, the caries prevalence was 2.0%, the mean DFS score was 0.04 (SD, 0.31). All permanent dental caries occurred on the first permanent molars. Carious tooth surfaces were identified as modified ICDAS code “A” to indicate initial caries and distinct visual change in enamel. The mean DAS score of non-cavitated caries in the first permanent molars was 0.18 (SD, 0.67). Logistic regression analysis showed that regional and gender factors were significantly related to the caries experience of these children. Conclusions The 6-year-old children from four regions of China had sever primary dental caries and the first permanent molars were at high risk for dental caries. It is critical to protect permanent teeth from caries as early as the eruption of the first permanent molars.

The Relationship

In order to predict the factors which affect the occurrence of dental caries in children after the age 18-months, we analyzed the relationship between the increment of the decayed, missing, and filled teeth (dmft) in children from 18-months to three-years of age and caries risk factors. Subjects were 392 infants who received both an 18-month-old check-up and a three-year-old check-up in Chiba city. Stepwise multiple logistic regression analyses were used to analyze the results with the increment of the dmft by various combinations of independent variables (sex, order of birth, sweets intake, beverage intake, tooth brushing and feeding). The most predictive factors for the increment of the dmft in upper anterior and molar were “breast feeding” and “bottle feeding” respectively. From these results, we concluded that bottle feeding and breast feeding were the risk factors for the increment of the dmft from the age of 18-months to three years.

The aim of the study was to assess the prevalence of dental caries of first permanent molars in a group of children of Craiova. The sample of the study consisted of 83 children aged 7-15 years. The children were examined in a dental office and for each patient it had been analyzed the clinical status of first permanent molars, and it had been calculated the DMFT index. 332 of first permanent molars of 83 children were examined. The percentage of caries damages of first permanent molars was: 6% of girls and 12% of boys had extractions, 21% of girls and 51% of boys had very damaged molars, 38% of girls and 66% of boys had at least one cavity of first permanent molars. The prevalence of caries increases with age, and the extracted molars were found to the children aged 10-15 years. The prevalence of first permanent molars caries is high. The study reveals high percentage of damaged and lost molars to the children aged under 15 years. It is necessary to apply preventive methods in order to improve children’s oral health.

Relevance. Prevention of caries of the first permanent molars is one of the most relevant problems in pediatricdentistry.Purpose – to develop an algorithm for prevention of first permanent molars caries in children with differentlevels of caries risk.Materials and methods. The article presents the results of the implementation of the algorithm for prevention of first permanent molars caries in children with different levels of caries risk. This algorithm includes a comprehensive assessment of the values of indices dmft, DMFT, OHI-S, and the patient's health group is also taken into account. The study involved 253 children aged 6-7 years divided into 4 groups: 3 groups of children depending on the health group and the control group. 3 subgroups were identified in each group – with a low, medium, and high caries risk. We developed preventive measures schemes were for children of each group including training in oral hygiene; controlled and home toothbrushing using fluoride-containing toothpastes; applications of varnishes containing fluoride, calcium, phosphates from 2 to 3 times a year; fissure sealing of the first permanent molars. We carried out these activities were for 24 months, and then evaluated theirs effectiveness. Children in the control group were trained in oral hygiene. The clinical effectiveness of medical prophylaxis was evaluated by changes in the above clinical indicators.Results. In group of children with medium caries risk the increase in caries was 0.09, and the reduction in caries was 89.65%. In children with a low and high caries risk no increase in caries was observed; the reduction in the intensity of caries was 100%. A significant decrease in OHI-S oral hygiene index values was noted in all groups (p < 0.05). We noted high preventive efficacy of fissures sealing in the first permanent molars. No occlusal surface caries developed in sealed fissures.Conclusions. The application of the proposed preventive schemes in patients demonstrates high efficacy of fluoride and calcium-containing varnishes and sealing the fissures of the first permanent molars.

The aim of this study was to describe the 2-year results of an individualized treatment program designed to control occlusal caries in erupting first permanent molars. The sample consisted of 145 five-to-six-year-old students divided into a control group (n=71) and a test group (n=74). All test children received a biannual basic preventive program and a recall system according to individual disease activity. The basic program consisted of 3 (March) and 2 (August) sessions of oral hygiene orientation and toothbrushing with fluoride gel. The analysis of the baseline and 1-2-year data showed a significant reduction in the number of active lesions in the test group. In the control group, there were initially 70 active lesions and after two years 68 surfaces remained with disease and 24 surfaces had been filled. The children in the test group had 80 surfaces with active lesions initially and after two years only 3 surfaces with disease remained. From the 15 cavitated lesions, only 5 surfaces needed to be filled. This program showed that care of erupting teeth on an individualized basis can control occlusal caries.

Study objectivesPerfluoroalkyl acids (PFAAs) are a class of anthropogenic and persistent compounds that may impact some biological pathways related to oral health. The objective of our study was to estimate the relationship between dental caries prevalence and exposure to four PFAA: perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS) in a nationally representative sample of US adolescents.Setting/DesignWe analysed cross-sectional data from the National Health and Nutrition Examination Survey from 1999 to 2012 for 12–19-year-old US adolescents.ParticipantsOf 10 856 adolescents aged 12 to 19 years who had a dental examination, we included 2869 with laboratory measurements for serum PFAA concentrations and complete covariate data in our study.Primary and secondary outcome measuresDental caries prevalence was defined as the presence of decay or a restoration on any tooth surface, or the loss of a tooth due to tooth decay. We used multivariable logistic regression to estimate the covariate-adjusted association between serum PFAA concentrations and dental caries prevalence, accounting for the complex National Health and Nutrition Examination Survey design.ResultsOf 2869 adolescents, 59% had one or more dental caries. We observed no associations between the prevalence of dental caries and serum concentrations of PFOA, PFOS or PFHxS. The adjusted odds of caries were 21% (OR 0.79; 95% CI 0.63 to 1.01), 15% (OR 0.85; 95% CI 0.67 to 1.08) and 30% (OR 0.7; 95% CI 0.55 to 0.90) lower among adolescents in the 2nd, 3rd and 4th serum PFNA concentration quartiles compared to adolescents in the first quartile, respectively. The linear trend for this association was not statistically significant.ConclusionPFOA, PFOS and PFHxS were not associated with prevalence of dental caries. The prevalence of caries was reduced with increasing serum PFNA concentrations; however, these results should be interpreted cautiously given that we were unable to adjust for several factors related to oral health.

This paper examines the factors affecting adolescent motherhood in Bangladesh using the 2007 Bangladesh Demographic and Health Survey data. Overall, 69.3 per cent of the married adolescents began childbearing. Among them 56.4 per cent were already mothers and 12.9per cent were pregnant for the first time. Of the adult married women age 20–49, 62.1 per cent initiated childbearing before age 19. The multiple logistic regression analyses revealed that women’s education, husband’s education, place of residence, ever use of contraceptive method, religion, wealth and region are important determinants of adolescent motherhood in Bangladesh.

Dutch Children

The aim of this study was to investigate potential differences in caries prevalence of children from ethnic minority groups compared to native Dutch children and the influence of socio-economic status (SES) and parent-reported oral health behaviour on this association. The study had a cross-sectional design, embedded in a population-based prospective multi-ethnic cohort study. 4,306 children with information on caries experience, belonging to 7 different ethnic groups, participated in this study. The decayed, missing, and filled teeth (dmft) index was assessed at the age of 6 and categorized in two ways for analysis: children without caries (dmft = 0) versus any caries experience (dmft >0) and children without caries (dmft = 0) versus children with mild caries (dmft = 1-3) or severe caries (dmft >3). Compared to native Dutch children, children with a Surinamese-Hindustani, Surinamese-Creole, Turkish, Moroccan, and Cape Verdean background had significantly higher odds for dental caries. Especially the Surinamese-Hindustani, Turkish, and Moroccan group had significantly higher odds for severe dental caries. Household income and educational level of the mother explained up to 43% of the association between ethnicity and dental caries, whereas parent-reported oral health behaviour did not mediate the association. Alarming disparities in caries prevalence between different ethnic (minority) groups exist, which cannot be fully explained by social inequalities. Public health strategies can apply this new knowledge and specifically focus on the reduction of ethnic disparities in oral health. More research is needed to explain the high caries prevalence among different ethnic minority groups.
