Autism is a lifetime developmental disability. Autism affects individuals from different ethnic backgrounds and social classes. Traumatic dental injuries are very common among children in India. TDI is most common among pre-adolescent and adolescent age groups. 16 patients were taken up in the study. Data was collected by reviewing the case sheets of patients with autism disorder from June 2019-April 2020. Data was tabulated and statistical analysis was done in SPSS version 19 using chi square test. It was found that 31.25% of the boys were affected with trauma in the study. Fall (80%) was the most common risk factor associated with trauma. Maxillary central incisors (37.5%) were the commonly fractured teeth. The results were statistically significant, since the p value was <0.05. Within the limits of the study it was found that children with ASD exhibit risk factors of fall to be the most common when compared to those without ASD. Prevalence of TDI was more in boys than girls.
