Abstract
The study aims to assess the relationship between body mass index (BMI) and dental developmental age in 4-10-year-old age group subjects.74 subjects were selected between the age range of 4-10 years. Height and weight were recorded for the determination of BMI. IOPA radiographs of the mandibular right first permanent molar were taken for estimation of dental age using Nolla’s method.The correlation between BMI and dental developmental age was statistically significant with boys showing greater advancement than girls. A strong positive correlation between dental developmental age and chronological age was found among the total study population. A statistically significant difference was observed in the mean difference between dental age and chronological age, which was higher in girls than in boys and higher among obese than in non-obese. Obese children have a higher rate of dental development compared to normal children. Hence, orthodontic treatment planning should be meticulously chalked out as obese children have accelerated dental growth and maturation.
