Cross-sectional study reveals body mass index influences Demirjian dental age estimation accuracy in children, suggesting weight status affects dental development timing.
Purpose: The aim of this study was to determine the relationship between body mass index (BMI) and tooth development in individuals with early and late mixed dentition and to evaluate the effect of changes in BMI on the accuracy of age determination.Material and Methods: The study included 281 children aged 6-12 years. Obesity classification (underweight, normal, overweight and obese) was made within BMI of the cases and dental ages were determined according to Demirjian’s method. Intraclass correlation coefficient (ICC) was used to evaluate the agreement between chronological age and age calculated according to Demirjian’ method. Statistical analyses were performed with SPSS 11.5 software and significance level was taken as 0.05.Results: The mean age according to Demirjian was 9.11±1.75 years. In BMI categories, ICC was 0.436 in underweight children, 0.408 in normal children, 0.579 in overweight children and 0.363 in obese children, and all values were statistically significant (p=0.015, p9 and ≤12 years (p
