Abstract

Background: Autism spectrum disorders (ASD) are a set of developmental, psychological, and neurological disorders that occur in early childhood. The most important characteristic of individuals with autism is difficulty in social interactions and communication. Researchers in the field of oral health have not paid enough attention to these individuals due to their specific behavioral characteristics. Therefore, due to the limitations of the studies in this field in Iran, increasing prevalence of autism, and importance of oral health in people with ASD, this study was conducted to evaluate the oral health status of primary school students with autism (7–15 years old) in autism schools in Tehran. Methods: Students from seven governmental special primary schools in Tehran were selected for this study. Data about oral health behavior and the presence of each of the seven barriers of tooth brushing task was collected via questionnaires completed by parents. During the dental examination, the cooperation level according to the Frankle Index, oral hygiene status according to the Simplified Oral Hygiene Index, and caries experience (DMFT) of the students were recorded by a calibrated dentist. A psychologist assessed the level of ASD using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM5). Data analysis including descriptive and regression analysis was done using the SPSS software version 24. Results: Two hundred and seventeen students aged 7–15 years participated in this study, of whom 65.4% brushed their teeth once or more every day, 85.7% had sugary snacks twice or less per day, 73.7% used fluoridated tooth paste, and 80% brushed their teeth with parents’ help. The most common barrier to tooth brushing was difficulty in brushing (51.6%). The cooperation level was definitely positive in 46.1%. The mean Simplified Oral Hygiene Index (OHI-S) and caries experience (DMFT) scores were 1.92 ± 0.55 and 2.36 ± 2.38, respectively. Conclusion: The clinical indices of OHI-S and caries experience (DMFT) were used to evaluate the oral health status in the students with ASD in Tehran, Iran. A better oral hygiene status was related to higher brushing frequency and lower sweet snack consumption. The findings of the present study indicate that educational interventions regarding oral hygiene and healthy diet may improve oral self-care in individuals with ASD. © 2022, The Author(s).
