The purpose of this study is to report base line information about characteristics, and dental experiences of a group of autistic children in three major cities of Saudi Arabia. Most of the children (76.2%) included in the study were diagnosed with autism before the age of 5 years. More than half of the children (53.7%) had no previous dental experience while 33% were treated under general anesthesia. The American Academy of Pediatrics' recommendations should be applied in Saudi Arabia to help improve the average age of diagnosis and make a positive effect on children with autism and their families. Regular visits to dental clinics should be recommended to all families with autistic children to reduce dental disease.
