Introduction: Photobiomodulation (PBM) has emerged as a promising modality in dentistry, with applications aimed at improving clinical outcomes and enhancing patient satisfaction. Despite growing interest in this field, a comprehensive understanding of research trends and contributions to PBM in dentistry is limited.
Objective: The objective of this review was to analyze the characteristics of published research on PBM applications in dentistry using multidimensional bibliometric analysis and science mapping methodologies.
Methods: A total of 399 publications from 2002 to 2023 were retrieved from the Scopus database for analysis. Bibliometric indicators, including publication trends, productive journals, authorship contributions, country-wise outputs, and keyword occurrences, were examined to identify research patterns and focal areas. The most significant keywords were “photobiomodulation”, “photobiomodulation therapy”, “laser”, “low-level laser therapy”, and “low-level light therapy”. To be considered for the review, an article had to focus on dentistry and be published in an English-language journal. Articles failing to meet these criteria were excluded from the analysis.
Results: The analysis revealed a steady increase in PBM-related publications over the past two decades. The journal Lasers in Medical Science emerged as the most productive in this field. Dr. Reza Fekrazad was the leading contributor, with 14 publications and 133 citations. Brazil was identified as the most prolific country in terms of output. These findings highlight the growing diversity and scope of PBM research in dentistry.
Conclusion: The study provides an insightful overview of the current research landscape in PBM applications in dentistry. By mapping key contributors, productive regions, and thematic areas, the findings serve as a valuable resource for scholars aiming to expand the knowledge base and address gaps in this discipline.
