| Outline of Final Research Achievements |
Previous studies have demonstrated the efficacy of topically administered metformin in the gingiva for inflammatory bone resorption and periodontal treatment. However, there have been no attempts to prevent the onset or progression of periodontitis with metformin. In this study, we aimed to clarify whether topical metformin administration to the gingiva is effective in preventing alveolar bone resorption.
It was suggested that topical metformin administration in the gingival tissues may also suppress the underlying inflammation caused by aging. Topical metformin administration suppressed inflammation and bone resorption during the development of experimental periodontitis in aged mice, and also reduced the number of TRAP-positive cells. These results suggest that topical metformin administration to the gingiva may be effective in preventing the onset of periodontitis.
