“…The Demirjian method shows a trend of overestimating chronological age in both the male and female groups of the southern China population, and the error was large, so it is considered unsuitable for the age estimation of the southern China population. This result is consistent with many studies in China 6 , 15 , 16 or Asian regions 17 . The Demirjian method was developed for age estimation of French-Canadians children, and the overestimation of the results in and around China suggests that the results of the age estimation are probably matched by the geographical proximity of the population.…”

Age estimation based on the mineralized morphology of teeth is one of the important elements of forensic anthropology. To explore the most suitable age estimation protocol for adolescents in the South China population, 1477 panoramic radiograph images of people aged 2–18 years in the South were collected and staged by the Demirjian mineralization staging method. The dental ages were estimated using the parameters of the Demirjian and Willems. Mathematical optimization and machine learning optimization were also performed in the data processing process in an attempt to obtain a more accurate model. The results show that the Willems method was more accurate in the dental age estimation of the southern China population and the model can be further optimized by reassigning the model through a nonintercept regression method. The machine learning model presented excellent results in terms of the efficacy comparison results with the traditional mathematical model, and the machine learning model under the boosting framework, such as gradient boosting decision tree (GBDT), significantly reduced the error in dental age estimation compared to the traditional mathematical method. This machine learning processing method based on traditional estimation data can effectively reduce the error of dental age estimation while saving arithmetic power. This study demonstrates the effectiveness of the GBDT algorithm in optimizing forensic age estimation models and provides a reference for other regions to use this parameter for age estimation model establishment, and the lightweight nature of machine learning offers the possibility of widespread forensic anthropological age estimation.

“…LBW refers to a newborn weighing ≤ 2.5 kg [ 28 ]. While previous studies on the association between LBW and dental caries in children have yielded inconsistent findings [ 28 – 30 ], our study demonstrated a positive association between LBW and caries. This relationship might be attributed to the higher prevalence of developmental defects observed in children with an LBW, as reported in previous studies [ 28 ].…”

Background Children aged 6–9 years are vulnerable to dental caries due to age-related limitations and a lack of adequate knowledge regarding oral health and hygiene practices. This study aimed to establish a cohort of children aged between 6 and 9 years and conducted a 12-month follow-up to examine the combined effect of pit and fissure sealant (PFS) application and oral health education on their oral health status. Methods A cohort study with 12-month follow-up was conducted in Liaoning province, China. A multi-stage stratified cluster sampling approach was employed in the study. The enrolled 6- to 9-year-old children were all from the selected primary schools, who had resided in the designated area for at least 6 months. Children who were unable to cooperate with the examiner or without informed consent from their guardians were excluded. Experienced dental professionals examined the oral health status of primary school children aged 6–9 years. All children and their guardians were mandated to complete a questionnaire (qualitative data) at the beginning of the study. In the experiment group, children underwent PFS application and chairside oral health education. Clinical examinations and questionnaire surveys were repeated at the 12-month follow-up. The chi-square test and binary logistic regression were conducted to investigate the potential risk factors associated with dental caries prevalence (dependent variable). Independent variables were items from the questionnaire (such as living place, parents’ education level and children’ birth weight). The significant variables identified in the chi-square tests were subsequently included in the binary logistic regression analysis. Results A total of 4,085 children aged 6–9 years were included in the study, with 1805 participants assigned to the experiment group and 2280 to the control group. At baseline, the caries rates of the experimental and control group were 77.95% and 80.35%, respectively without any statistically significant differences. However, at the 12-month follow-up, the caries rate in the experimental group (83.65%) was significantly lower than that in the control group (86.62%) (P < 0.05). The results from the binary logistic regression analysis indicated that parents with a college degree and children in the experimental group exhibited lower caries rates. Conversely, higher caries rates were associated with the consumption of sweet beverages and foods more than once a day and a lack of knowledge regarding the causes of caries (P < 0.05). Conclusions In Liaoning, China, children aged 6 to 9 years exhibited a high prevalence of dental caries. Several factors, including the parent’s education level, the frequency of consuming sweet beverages and foods, and the children’s understanding of the cause of caries, significantly affected the caries prevalence rates. The implementation of PFS application and oral health education effectively reduce the caries rate among the surveyed children.

“…Dental caries are one of the most prevalent and dangerous oral diseases worldwide (GBD 2016 Disease and Injury Incidence and Prevalence Collaborators, 2017), particularly prevalence among adolescents (Kazeminia et al, 2020). Recent research has shown that the frequency of dental caries among Chinese teenagers ranges from 30.9% to 58.1% (He et al, 2022; Shi et al, 2022; Weng et al, 2021). Due to the irreversible nature of dental caries, preventing it during adolescence is essential, as it affects the quality of life and indirectly contributes to a decrease in the nation's productivity (Meier et al, 2017).…”

ObjectivesThis study investigates the relationship between emotional symptoms and dental caries in adolescents and the role of dietary patterns as mediating variables.MethodsThis cross‐sectional study used a multistage stratified random sample of schools, in Jiangsu, with a sample of 17,997 adolescents aged 11–19. Measures included emotional symptoms, dental caries, toothbrushing frequency, and dietary patterns. Logistic and Poisson regression models were conducted to test mediation hypotheses.ResultsThe decayed, missing, and filled teeth index (DMFT) was related to depressive symptoms following adjustment for other variables (incidence rate ratios [IRR] = 1.09; p < 0.05), but not to anxiety symptoms level (IRR = 1.02; p > 0.05). The link between depressive symptoms and DMFT had a partial mediation impact on toothbrushing frequency (a, b, c′ all p < 0.05). Sugary foods, but not fried foods, partially mediated the link between depressive symptoms and caries when toothbrushing frequency was adjusted.ConclusionThere are direct and indirect associations between emotional symptoms and caries; the latter may be due to changes in oral health behaviours that increase the risk of caries.
