Assessment of the relationship between body mass index (BMI) and dental age
Abstract: The aim of the study was to determine the rela-tionship between Body Mass Index (BMI) and accelerated dental development. The dental developmental ages of 100 children aged between 8 and 12 years were determined using the Demirjian method and panoramic radiographs. BMI status was determined for each subject on the basis of the system developed by the International Obesity Task Force. There was a significant direct relationship between dental development and BMI (P < 0.01). Obese children have a higher rate of dental development compared to normal children. CLINICAL RELEVANCE: This is an important variable to be considered when planning for dental and orthodontic treatments in obese children. Brief objectives statement: Overweight or obesity can accelerate dental development. Accelerated dental development in overweight children is important to be considered in pediatric dentistry and orthodontics.
