Global Research Trends on Masticatory Performance and Glycemic Regulation: A Bibliometric Analysis

Abstract

Objectives: This study aimed to map the global scientific landscape and research evolution on the relationship between masticatory performance and blood glucose levels using bibliometric analysis.Methods: This quantitative-descriptive bibliometric study analyzed publications from the Scopus database covering the period 1994-2025.Keyword combinations related to mastication and glycemic response were used for the search.Data were analyzed using R Studio (v2024.4.1),VOSviewer (v1.6.20), and Tableau (v2023.2) to identify bibliometric indicators, collaborative networks, and thematic trends.Results: A total of 652 publications from 311 sources were analyzed.Research output grew from 10 articles/ year (1995-2005) to 34 articles/year (2017-2025).Asian countries led the research effort (46.80%), with Japan contributing the most (97 publications).Tokyo Medical and Dental University was the most productive institution, while Hirano Hirohiko and Watanabe Yutaka were the most cited authors (9 publications; 795 citations each).Major publication outlets included the Journal of Oral Rehabilitation and Gerodontology.Thematic evolution progressed from observational studies ( 2010-2013) to mechanistic research (2014-2017) and clinical interventions (2018-2020 ).Conclusion: There has been substantial growth in research examining the relationship.Future research should address geographical imbalances, promote methodological standardization, and encourage future longitudinal and interventional research.
