Impact of Childhood Obesity on Dental Crowding, Arch Shape, and Arch Width

The prevalence of childhood obesity is on the rise in the world and the United States and has been shown to influence growth and craniofacial development. Obese children have been shown to have precocious dental development. This study explores the effects of obesity on dental crowding, arch shape, and arch width in children from age 5-17.9 with various body mass indices (BMI). Patients presenting at the University of Illinois at Chicago for their orthodontic records appointment were recruited. Patients were categorized according to their BMI. The intraoral scans were then analyzed to assess dental crowding and arch width (intercanine and intramolar) using OrthoCAD software and arch shape using Stratovan checkpoint. There was a significant association found between BMI and maxillary intercanine distance, Frankfort mandibular plane angle, and arch shape. Increased obesity was found to have significant differences in their arch morphologies rather than dental crowding.
