Abstract
Background and objective: children’s oral health education plays an important role in preventing oral diseases and promoting lifelong healthy behaviors. This study aimed to systematically map global research trends, intellectual structure, and thematic development of oral health education in children.

Materials and Methods: This bibliometric analysis publications indexed in the Scopus database from 1929 to 2023. A total of 11,389 records were initially retrieved, of which 335 articles met the inclusion criteria and were analyzed. Data were examined using bibliometric indicators, co-citation analysis, bibliographic coupling, and keyword co-occurrence mapping with VOSviewer (version 1.6.20).

Results: The analysis identified ten major research clusters, including caries prevention, behavioral interventions, clinical approaches, public health promotion, and standardized indicators. The United States (43 publications, 606 citations) and India (42 publications, 573 citations) were the most productive countries. Influential studies by Samuel (2020) and Carvalho (1992) showed strong citation links. Recent research trends emphasize school-based interventions, preventive programs, and behavioral change strategies.

Conclusion: This study demonstrates a shift in pediatric oral health research from clinical treatment toward prevention-oriented and education-based approaches. The findings provide evidence for identifying research gaps, supporting international collaboration, and informing the design of effective oral health promotion programs and policies, particularly for underserved populations.
