Abstract: Objective: To investigate the current status of oral health self -efficacy in elderly patients with chronic periodontitis and to analyze its influencing factors. Methods: A convenience sampling method was used to investigate the oral health self-efficacy in 288 elderly chronic periodontitis patients by applying the General Situation Questionnaire, the Chinese version of Geriatric Self-Efficacy Scale for Oral Health (GSEOH) and the Dental Fear Scale (DFS). Results: The GSEOH score of elderly patients with chronic periodontitis was 57.84±4.28 and the DFS score was 37.69±9.78. The level of dental fear in elderly patients with chronic periodontitis was negatively correlated with the total score of GSEOH (r=-0.457, P <0.001). The multiple regression analysis showed that age, education level, monthly income, residence, severity of periodontitis, and the level of dental fear were the influencing factors of self -efficacy in elderly patients with chronic periodontitis (P<0.05). Conclusion: The level of oral health self-efficacy of elderly patients with chronic periodontitis needs to be improved, and nurses should pay attention to assessing the relevant influencing factors of the patients and adopting targeted nursing interventions to enhance their oral health self-efficacy.

摘要： 目的：调查老年慢性牙周炎患者口腔健康自我效能现状并分析其影响因素。方法：采用便利抽样的方法，应用一般情况调查表、中文版口腔健康自我效能量表（GSEOH）和牙科恐惧量表（DFS）对 288 例老年慢性牙周炎患者进行调查。结果：老年慢性牙周炎患者的 GSEOH 的得分为（57.84±4.28）分，DFS 得分为（37.69±9.78）分；老年慢性牙周炎患者牙科恐惧水平与 GSEOH 总分呈负相关（r=-0.457，P<0.001）；多元回归分析显示，年龄、教育程度、月收入、居住地、牙周炎严重程度、牙科恐惧水平是老年慢性牙周炎患者口腔健康自我效能的影响因素（P<0.05）。结论：老年慢性牙周炎患者的口腔健康自我效能水平有待提高，护士应评估患者的相关影响因素，并采取针对性的护理干预，以提升其口腔健康自我效能。
