Dental caries status in individuals with hearing difficulties: A systematic review and meta-analysis.

AIMS: The purpose of the systematic review and meta-analysis was to assess the dental caries status in individuals with hearing difficulties. METHODS AND RESULTS: Searches were conducted in six databases with no restriction on publication date. The cross-sectional and comparative cross sectional studies assessing the dental caries status of hearing impaired individuals using standardized evaluation criteria were included. PubMed, Web of Science, Cochrane, Wiley Online, Lilacs, and Scopus databases were searched to identify the relevant papers published before August 1, 2021. The risk of bias assessment was carried out by New Castle Ottawa Quality Assessment Scale. Three thousand three hundred thirty five potentially relevant references were identified in the systematic literature search. Thirteen relevant publications that fulfilled the eligibility criteria were included in the systematic review and the meta analysis. The overall analysis of the included studies revealed pooled dental caries prevalence of 58.0% (95% CI 0.41-0.74) among the hearing impaired individuals. The overall dental caries experience of the included studies showed a mean pooled DMFT of 2.68 (95% CI 1.24-4.12). CONCLUSION: The present systematic review and meta-analysis reported high dental caries prevalence in hearing impaired individuals.
