Qualitative research in oral health in India: A bibliometric analysis

A qualitative research approach is necessary to understand the complexities of social, behavioral, and systemic factors influencing oral health. Despite having a large dental education infrastructure and workforce, a limited number of studies have been published by Indian dental researchers utilizing a qualitative methodology.

Map the existing literature to understand the current landscape of qualitative research in oral health in India.

A comprehensive search of prominent databases, along with handsearching, was conducted to shortlist studies based on a predefined criterion. Eligible studies underwent thematic categorization and bibliometric assessment. Keyword co-occurrence and network analysis were performed using VOSviewer software to identify conceptual linkages and emerging research themes.

Sixty-four studies met the inclusion criteria. Of these, 56 % were pure qualitative and 43 % were mixed-methods studies, with most published in the last five years. Key focus areas include tobacco cessation, pediatric oral health, and barriers to accessing dental services. Methodologically, the studies relied heavily on interviews and focus group discussions, with limited theoretical integration. Thematic clusters showed dominance of behavior-focused research and regional disparities in study distribution.

This is the first review to comprehensively chart the evolution of qualitative research in oral health in India. While momentum is growing, significant gaps remain in methodological depth and thematic diversity. Strengthening training, institutional support, and theoretical engagement is essential for advancing qualitative dental research in India.
