Methods: Databases, including PubMed and Scopus, CINAHL, Web of Science, PsycInfo were systematically searched for English Language studies conducted among Indians up to July 2022. Two independent reviewers assessed studies selected for retrieval for methodological quality using standardised quality assessment instruments for analytical cross-sectional studies in JBI SUMARI.

Results: Fourty one publications were included in this review (N = 23,090). Studies includes both cross sectional study and Randomized Controlled Trials. Based on the JBI critical appraisal tools, the quality of the included studies was low to high. Twenty-six studies were considered for the meta-analysis. Individuals with dental caries [OR: 3.54 (95% CI 2.24- 5.60), ten studies, 4945 participants] and malocclusion [ OR: 5.44 (95% CI 1.61, 18.39), six studies, 3720 participants] had poor OHRQoL compared to individuals without oral conditions.

Conclusions: Despite the various definitions of the exposures and instruments used to assess Oral Health-Related Quality of Life, our review found that people with dental caries and malocclusion have a significantly higher experience of poor quality of life.
