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.

ABSTRACT Aim To evaluate the prevalence of molar incisor hypomineralization (MIH) and its relationship with dental caries in school children of Udupi district. Materials and methods A total of 352 school children were recruited for this study. The European Academy of Pediatric Dentistry (EAPD) 2003, criteria were followed for diagnosis of MIH. Dental caries was recorded using World Health Organization (WHO) guidelines (1997) under natural day light. Results The prevalence of MIH was seen to be 27% (n = 95). A total of 323 teeth had hypomineralization (106 were incisors and 217 were molars). The lower molars (n = 127) were more frequently affected than the upper molars (n = 90). Overall the maxillary incisors (n = 68) were more affected than the mandibular incisors (n = 38). Amongst the children with MIH, the mean number of decayed teeth was significantly lower than mean number of hypomineralized teeth in first permanent molars and first permanent molars and incisors (p < 0.001 and < 0.001) respectively. The mean decayed teeth in first permanent molar and incisors were significantly higher in subjects with MIH than without MIH (p < 0.001). Poisson regression analysis showed a significant positive association between MIH and dental caries (B = 1.43; p < 0.001). Conclusion The prevalence of MIH was relatively high and was associated with dental caries. How to cite this article Tadikonda AN, Acharya S, Pentapati KC.

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.

Abstract Background: Lisu is an ethnic minority group and most of them are living in Yunnan, China. This study investigated the oral health status among 12-year-old Lisu children in Yunnan.Method: This survey employed a multistage sampling method to recruit 12-year-old Lisu children. Two calibrated dentists performed the oral examinations in the primary schools. They examined dental caries, gingival bleeding and dental fluorosis using the diagnosis criteria recommended by the World Health Organization. A self-administrated questionnaire was distributed to the children to collect their sociodemographic background information and oral health-related behaviours. A chi-square test, the Mann-Whitney U test, zero-inflated negative binomial (ZINB) regression and multivariate logistic regression were used for statistical analysis.Results: This survey invited 512 children, and 482 children (48% boys) participated in the study (response rate: 94%). Their caries prevalence was 35% and their caries experience in mean (SD) DMFT scores was 0.63 (0.10). The mean (SD) DT score was 0.60 (1.10), consisting 95% of the mean DMFT scores. No dental fluorosis was observed; whereas 426 children (88%) had gingival bleeding. Results of ZINB model indicated sex and sugary-snacking habits were related to the dental caries experience (p<0.05). The gingival-bleeding prevalence was associated with the mother’s education level, the child’s monthly-pocket money and daily toothbrushing frequency (p<0.05).Conclusion: Dental caries and gingival bleeding were prevalent among 12-year-old Lisu children in the Yunnan province in China, and most of the decayed teeth were unrestored. Dental fluorosis was not observed in the children.

Objectives: National oral health data is required to assess a population's oral health needs, monitor oral health, plan effective intervention community programs and health policies, and evaluate progress toward health objectives. The study aimed to estimate the prevalence, severity, and inequality in dental caries distribution among Korean young people. Study Design: Trained, calibrated examiners at the Korea Ministry of Health & Welfare conducted epidemiological surveys in 2000, 2006, and 2012 during which dental caries were assessed according to World Health Organization (WHO) diagnostic criteria. Decayed, missing, and filled surface and tooth (DMFS/DMFT) indices were estimated. Results: DMFT indices decreased in all regions between 2000 and 2012, with values of 3.3, 2.2, and 1.8 for 12-year-old children in 2000, 2006, and 2012, respectively. The prevalence of caries was higher among female versus male subjects and in rural versus urban areas. Conclusions: Despite the observed decrease in caries experience indicators in Korea, the caries prevalence remains considerably higher than that in European countries and than the targets set by WHO within the Health21 policy framework. Therefore, Korea apparently retains further potential for caries reduction. Community-based oral disease prevention programs are urgently needed to promote oral health.

Introduction: The prevalence of high dental anxiety varies from 2% to 30% worldwide depending on the study population, the methods applied, and the cut-off scores used. There is strong evidence that dental anxiety is associated with dental attendance; it has been reported that individuals with higher dental anxiety tend to visit the dentist irregularly, which in turn may lead to deterioration in oral health. Studies have demonstrated that dental anxiety is associated with poor self-reported and clinically assigned oral health, more decayed and missing teeth, fewer filled teeth and worse periodontal health. Dental students are the future dental doctors who will be dealing with fearful patients in future. Knowing the facts on dental anxiety will have positive impact while treating and dealing such patients. Objectives: The overall objectives of the study were to assess level of anxiety and its possible effect on prevalence of caries among dental students studying at Kathmandu medical college and Dental hospital. Specific: To access the level of anxiety among dental students of different years (from first year to final year) along it was further focused to analyse the level of anxiety among male and female dental students. Methodology: A cross sectional study was conducted to choose a random convenient sample. The data were collected from dental students of first year to final year studying at Kathmandu medical college dental hospital–KMCDH. A structured questionnaire based on modified dental anxiety scale was used to collect the data. Patients were examined for dental caries prevalence using decay, missing and filled teeth (DMFT) index according to World Health Organisation guidelines. Results: The highest MDAS was seen among the younger batches and the mean values for MDAS declined with higher batch of dental students. The mean dental anxiety score for males was 8.9 and 15.5 for females. The difference was statistically significant the most fearful stimulus in dental clinic for both genders was local anesthetic injection, followed by drilling of teeth. Conclusion: Dental anxiety remains a significant problem for many patients of both gender and different age groups of examined students. Dental anxiety has a negative effect on oral health status by increasing the prevalence of decayed teeth. Further studies should be carried out using large random samples before generalizing this conclusion.

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.

INTRODUCTION : Good oral health is important and have major impact on peoples daily lives and activities. This study  was conducted to assess dental caries, periodontal health, and malocclusion of school children aged 12 and 15 years and to compare them in government and private schools. MATERIAL AND METHODS: A cross-sectional study of 12- and 15-year-old children in government and private schools was conducted in Rupendehi (Bhairahawa) Nepal. A sample of 1011 school children (both males and females) was selected by a two-stage cluster sampling method. Clinical recordings of dental caries and malocclusion were done according to World Health Organization diagnostic criteria 1997. Periodontal health was assessed by Community Periodontal Index of Treatment Needs index. The data collected was analyzed by SPSS versons 13. The statistical tests used were t-test and Chi-square tests.RESULTS: The prevalence of dental caries was 32.6% and 42.2% at 12 and 15 years of age, respectively. At 12 years of age, the mean decayed, missing, filled teeth were 0.62 ± 1.42 and it was 1.06 ± 2.93 at 15 years of age. Females had higher level of caries than males at both the ages. At both ages, mean of decayed teeth was statistically higher in government schools as compared with private schools. Children in government schools had significantly less number of mean filled teeth at both ages as compared with private schools. The healthy component of gingiva was present in higher percentage of children in private schools as compared with government schools at both the age groups. The prevalence of malocclusion among the 12- year-old (58.1%) was more as compared with that among the 15-year-old (53.5%).CONCLUSION: The caries experience of 12 and 15 years old children was low but the prevalence of gingivitis and malocclusion was quite high. Effective oral health promotion strategies need to be implemented to improve the oral health of school children further in Rupendehi District , Bhairahawa, Nepal.DOI: http://dx.doi.org/10.3126/jucms.v2i3.11822 Journal of Universal College of Medical Sciences Vol.2(3) 2014: 15-19
