A systematic review of population-based gingival health studies among children and adolescents with autism spectrum disorder
The Saudi Dental Journal
Abstract
The prevalence of autism spectrum disorder (ASD) is close to 1% in the United States of America and other countries. Special attention should be given to oral health in individuals with ASD as they are often affected by oral diseases. However, gingival health in children with ASD and adolescents is controversial in terms of the severity of disease and number of people affected.
Aim
To conduct a systematic review and meta-analysis to assess the gingival health status of children and adolescents with ASD.
Methods
The search was conducted using eight databases for articles that met the inclusion and exclusion criteria. This search produced 742 relevant papers, but only five with sufficient data on gingival and plaque indices were eligible for inclusion in this systematic review and meta-analysis.
Results
The homogeneity of the sample was tested using the Cohen Q test, which identified significant heterogeneity (P<0.0001), indicating the use of the random effect’s standard mean difference. Significantly higher gingival index and plaque index values were found in children and adolescents with ASD than in children without ASD.
Conclusion
Individuals with ASD need help and better access to oral healthcare. Further investigation is needed with regard to gingival health in individuals with ASD and caries risk assessment to understand how this disorder affects oral health. A standardized index for gingival health will help in the inclusion of more studies to assess gingival health in children and adolescents with ASD.
