Abstract Objectives This study evaluated the impact of self-management interventions based on the COM-B model on peri-implant conditions in older adults with periodontitis. Materials and methods The patients were randomly divided into two groups: Group 1 (control group) received only an oral health education (OHE) pamphlet. Group 2 (test group) performed a self-management intervention based on the COM-B model. Each patient was examined for the most inflammatory implant. The measurement parameters included self-efficacy, self-management ability, and clinical indicators such as probing depth (PD), bleeding on probing (BOP), modified gingival index (mGI), modified plaque index (mPI), and peri-implant mucositis severity score (PMSS). The data was collected at baseline, 4, 8, and 12 weeks. Results 42 patients underwent testing for 3 months. After 12 weeks, the improvement of self-efficacy, self-management ability, and the reduction of BOP, mPI, and PMSS in the test group was significantly higher than in the control group. Conclusion The study suggests that self-management interventions based on the COM-B model can enhance the self-management ability of older adults with periodontitis and reduce peri-implant inflammation. This method is more effective than distributing OHE pamphlets. Trial registration The randomized controlled clinical trial was registered on Chinese Clinical Trial Registry (No. ChiCTR2400082660, Date: 03/04/2024). |
