Autism is a psychological development disorder that starts from infancy. Autistic patients exhibit impaired social and communication abilities, limited interests, and stereotyped repetitive behavior. These patients have difficulties with self-care and cooperation during dental treatment, which are challenging for dentists. Familiarization with the oral characteristics of autistic patients will lead to better dental treatment results. This review investigates the oral diseases in autistic patients. These diseases include caries, factitial oral lesions, orofacial pain, and periodontal diseases. Intervention measures, such as oral hygiene instruction and dental treatment, were also examined.
