Abstract Background This study aimed to explore the trend and risk indicators for dental caries of children aged 12 years in China based on national oral health survey data in 2005 and 2015. Methods Research data were from the two latest national oral health surveys conducted in mainland China, including 30 and 31 provinces, autonomous regions, and municipalities in 2005 and 2015, respectively. Children aged 12 years were clinically examined for dental caries and dental fluorosis according to the World Health Organization criteria. Sociodemographic characteristics and oral health-related behaviours were collected using questionnaires. Multilevel zero-inflated negative binomial regression model was used to investigate the association between dental caries severity and dental fluorosis, sociodemographic characteristics, and oral health-related behaviours. Results The final analyses included 12,350 and 27,818 children surveyed in 2005 and 2015, respectively. The standardized prevalence of dental caries increased from 27.05% (95% confidence interval [CI], 24.25-28.85) in 2005 to 37.92% (95% CI, 34.94-40.90) in 2015, and the respective standardized mean decayed, missing, filled teeth (DMFT) index scores increased from 0.50 (standard deviation [SD], 1.04) to 0.83 (SD, 1.45) (P < 0.001). Fujian province had the highest increase in dental caries, followed by Liaoning, Heilongjiang, Hainan, and Yunnan. Results revealed that children who were girls, more frequently experienced dental pain, and had more recent dental visits, had significantly higher DMFT scores after adjusting for the survey year and other variables (all P < 0.05). Conclusions Dental caries of 12-year-old children in China deteriorated from 2005 to 2015, particularly in the northeast and southwest regions. Dental caries was associated with sex, dental pain, and dental service utilization.

Abstract Background Children suffer a significant burden of oral diseases which impacts their quality of life, and general health. Many epidemiological studies have looked at oral health status and treatment needs among children in urban and rural areas across different age groups. There was limited literature assessing the oral health status among children in tribal areas, which presents unique challenges in terms of: topography, availability of health services, and complex socio-cultural health practices. Methods Cross-sectional study was conducted among 655 children across six schools between 12-15 years in Jawadhi Hills, Tamil Nadu, India. World Health Organization's, Oral Health Surveys were used for clinical and risk factor assessments. Clinical examination was conducted, and self-assessed questionnaire was administered to the children to assess the risk factors to poor oral health. Since dental fluorosis was common, drinking water samples were collected to assess fluoride levels in the community. Results Prevalence of dental caries and gingivitis (gum disease) was found to be 22.3% and 87.3% respectively. Dental Pain was reported by 57% of children as the most common reason to visit the dentist. Prevalence of dental fluorosis was found to be 53.6%. Multiple logistic regression showed: gender, dental fluorosis, diet, and maternal education significantly associated (p &lt; 0.005) with dental caries. Fluoride levels in water was found to be higher than permissible limits (&gt;1.5 ppm). Conclusions Children requiring treatment (∼ 200) were referred to the local hospital, and treatment was done free-of-cost. School authorities were informed about the current oral health status of children and advised to conduct regular health education & dental camps; the importance of girls' education was emphasized. Local authorities were alerted about the fluoride-rich water situation in the community and educated about defluoridation methods that the community can employ at household level. Key messages Evidence-based burden of oral diseases was presented to the local authorities for the first time, with a call for action. A referral system was established between the schools and the local hospital, to ensure continuity of oral health care for the children.

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.

Abstract Background Lisu is an ethnic minority group living in Yunnan, a province in Southwest China. This study investigated the oral health status among 12-year-old Lisu children in Yunnan. Method: A multistage sampling method was adopted to recruit 12-year-old Lisu children from primary schools. A self-administrated questionnaire was distributed to the children to collect their sociodemographic background information and oral health-related behaviours. Two calibrated dentists performed the oral examinations in the primary schools. They examined dental caries, gingivitis and dental fluorosis using the diagnosis criteria recommended by the World Health Organization. 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 A total of 512 Lisu children were invited, and 482 children (48% boys) participated in the study (response rate: 94%). The caries prevalence was 35% and 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. Gingivitis was found on 426 children (88%), while no dental fluorosis was observed. Results of ZINB model indicated sex and sugary-snacking habits were related to the dental caries experience (p < 0.05). The prevalence rate of gingivitis 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 gingivitis 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.

Background: The aim of this cross-sectional study was to investigate the oral health status of Hani 12-year-old children in Yunnan, a province in Southwest China. Method: This study employed a multistage sampling method to recruit children from local primary schools. Two calibrated dentists examined the status of dental caries, gingival bleeding and dental fluorosis by adopting the diagnosis criteria recommended by the World Health Organization. A self-administrated questionnaire was distributed. The chi-square test and multivariate logistic regression were conducted. Results: This study invited 480 Hani children, and recruited 413 children (52% boys) (response rate: 86%). The dental caries prevalence was 52%, and the caries experience associated with the mean (standard deviation) decayed, missing and filled teeth (DMFT) score was 1.10 (1.46). Gingival bleeding was diagnosed in 252 children (61%), and dental fluorosis was found in two children (0.5%). The results of the regression model indicated the prevalence of dental caries were associated with sugary snacking habits (p = 0.002). The prevalence of gingival bleeding was related to the mother’s education level as well as the child’s monthly pocket money (p < 0.05). Conclusion: Dental caries and gingival bleeding were prevalent among 12-year-old Hani children in the Yunnan province in China. Dental fluorosis was uncommon.

Abstract Background Childhood dental caries can affect the children’s and their parents’ oral health-related quality of life. The aim of the present study was to evaluate the impact of oral and dental health conditions on the oral health-related quality of life in preschool children and their parents. Methods In this descriptive-analytical cross-sectional study, samples were selected from children 3 to 6 years old enrolled in licensed kindergartens using "proportional allocation" sampling. Then, the parents of the children were asked to complete the Early Childhood Oral Health Impact Scale (ECOHIS). Results In this study, 350 children aged 3 to 6 years were evaluated with a mean age of 4.73 years. The mean dmft index (decayed, missed, and filled teeth) was 3.94 ± 4.17. The mean score of oral health-related quality of life was 11.88 ± 6.9, which 9.36 ± 5.02 belongs to the impact on children and 2.52 ± 3.20 to parents' impact. Conclusions The mean score of ECOHIS increased with the dmft index increase in children, indicating a significant relationship between the dmft and ECOHIS score. These outcomes can be used as proper resources to develop preventive policies and promote oral health in young children.

This study assessed oral health outcomes (perceived dental treatment need, untreated dental caries, gingival bleeding, periodontal pockets, and pain in teeth and gums), in relation to color/race inequalities among adolescents in each Brazilian region. The database included dental examination and interview of 16,833 15-19-year-old adolescents, surveyed by the Brazilian health authority, from May 2002 to October 2003, in accordance with international diagnostic criteria standardized by the World Health Organization. Prevalence ratios estimated by Poisson regression, and controlled by socioeconomic status and access to fluoridated piped water, assessed oral health differentials among color/race groups and country's regions. Except for periodontal pockets, prevalence figures were higher in the North and Northeast: perceived dental treatment needs, untreated dental caries, gingival bleeding at probing and pain in teeth and gums varied between 80-83%, 75-76%, 38-43%, and 17-18%, respectively, in these regions. Adolescents living in the Southeast - the richest Brazilian region - presented a better general profile of oral health than their counterparts living in the remaining regions; they had a lower prevalence of untreated dental caries (54%) and unfavorable gingival status (29%). However, the Southeast presented color/race inequalities in all oral health outcomes, with a poorer profile systematically affecting browns or blacks, depending on the oral health condition under consideration. These results reinforce the need for expanding the amplitude of health initiatives aimed at adolescent oral health. Socially appropriate health programs should concurrently aim at the reduction of levels of oral disease and its inequalities.

Objectives: To assess oral health status and practices of 5- and 12-year-old Tribal school children.Methods: A total of 418, 5-year-old children and 327, 12-year-old children were enrolled. Information on demographic characteristics of participants along with oral health behavior was collected. Clinical data were collected on dental fluorosis, periodontal status, dental caries and treatment needs. Dean's index criterion was used to assess dental fluorosis. Community Periodontal Index (CPI) for periodontal conditions and Dentition status and treatment needs for dental caries were recorded. Results: Between meal sugar consumption was high (100%). None of the children in both the age groups had visited trained health personnel for dental treatment. Dental fluorosis prevalence in 5- and 12-year olds was 11.9% and 22.9% respectively. Bleeding on probing and calculus was common between both the age groups. A low mean number of healthy sextants were found and this decreased with age. Mean dmft/DMFT values for 5- and 12-year olds were 4.13 ± 3.90 and 1.15 ± 1.62. Significant caries index (SIC) scores for 5- and 12-year olds were 7.17 ±4.30 and 3.78 ± 3.21 respectively. Conclusion: The present study reveals high sugar consumption, dental fluorosis, poor oral hygiene, and untreated dental disease of tribal children. Under these circumstances, the implementation of preventive programs including restriction of sweets in school premises for the tribal children is the key to good oral health.
