Brief Report: Estimating the Dental Age of Children with Autism Spectrum Disorders

Determining a patient's dental age is essential from the dental standpoint but can also have connotations of a forensic, anthropological and medicolegal nature. In this study, we assessed the correspondence between dental age and chronological age in a group of 50 children with autism spectrum disorders, with a chronological age range of 3-17 years. The dental age was calculated using panoramic radiography images, applying linear regression models derived from the classical indices by Nolla and Demirjian. In 2 of every 3 boys, the dental age was ahead of the chronological age, and in almost 1 of every 3 cases, the difference was ≥ 12 months. In the girls, conversely, we found no significant differences between dental age and chronological age.
