Abstract

Objective: This study aimed to determine the relationship between nutritional status and DMFT among adults in Banten using Riskesdas 2018 data. Material and Methods: The design of this study was cross-sectional, with a total sample of 1580 respondents aged 18-95 years. The relationship between BMI and DMFT was analyzed using Cox regression analysis, controlled for age, gender, educational level, work status, timing of tooth brushing, sweet food consumption, and diabetes mellitus status. Ethical permission was obtained from the YARSI University Research Institute, reference number No: 406/KEP-UY/BIA/XII/2021. Results: The mean DMFT was 8.3 (± 7.9). The prevalence of decay was 87.7%. DMFT distributions were as follows: very low, 46.7%; low, 17.5%; moderate, 16.1%; and high, 19.7%. BMI distribution was as follows: thinness 2.7%, underweight 7.7%, normal 53.2%, overweight 25.4%, and obese 11.0%. In multivariate analysis, overweight and obesity (BMI ≥ 25) were associated with a lower risk of having decay compared to normal BMI, with PRs of 0.69 and 0.62, respectively. Thin individuals (BMI < 17) and those underweight (BMI < 18.5) had a higher risk of caries compared to those with normal BMI. A significant inverse association between obesity and dental caries was observed. Overweight and obesity were not risk factors for having decay/caries. Conclusion: The DMFT index is complex and influenced by multiple factors, such as age and diet. Inconsistent results regarding the relationship between BMI and DMFT across studies indicate the need for more comprehensive, longitudinal research to clarify this relationship.
