目的 探讨3M复合树脂填充乳牙龋齿患儿治疗中的临床价值。方法 回顾性收集2023年4月至2025年4月我院口腔科128例乳牙龋齿患儿临床资料，根据治疗方法不同分为对照组（高强度玻璃离子填充，67例）、观察组（3M复合树脂填充，61例），采用倾向匹配评分法匹配，按照1:1配对选例，两组均纳入53例。比较两组疗效、治疗前后疼痛程度[Wong-Baker面部疼痛评分量表（Wong-Baker评分）]、牙髓活力、牙齿敏感性、龈沟液炎症因子[白细胞介素（IL）-6、IL-8、单核细胞趋化蛋白-1（MCP-1）]、儿童口腔健康影响量表（ECOHIS）评分及并发症。结果 观察组治疗总有效率94.34%高于对照组81.13%（P＜0.05）；治疗后1周观察组Wong-Baker评分、牙髓活力评分低于对照组，牙齿敏感性分级优于对照组（P＜0.05）；治疗后1周，观察组龈沟液IL-6、IL-8、MCP-1水平低于对照组（P＜0.05）；治疗后6个月，观察组口腔症状、口腔功能、心理状态评分低于对照组（P＜0.05）；两组并发症发生率比较，无显著差异（P＞0.05）。结论 3M复合树脂填充治疗乳牙龋齿患儿效果显著，能抑制龈沟液炎症，降低牙齿敏感性，提升牙髓活力，缓解患儿疼痛，改善口腔健康，且安全性较高。

目的 通过关注追踪中老年人口腔健康问题对生活质量的影响,系统梳理中老年人口腔健康的相关影响因素及其关系,为此类人群的口腔健康及其相关生活质量的活动开展提供调研依据。方法 随机抽取2022年10月—2023年5月之间的266名中老年人参与调查,按照“病因链”收集该类人群的社会学特征、日常口腔保健行为、身体健康状况,分析评价中老年人口腔健康相关生活质量。结果 266名中老年人口腔健康常识和行为得分平均为（30.69±8.98）分,口腔健康评估平均为（8.59±3.68）分,口腔健康相关生活质量GOHAI总分为（25.65±8.10）分。单因素分析显示,人口学特征与一般身体健康状况、口腔健康常识和行为以及口腔健康情况与中老年人的口腔健康相关生活质量的GOHAI得分密切相关（P<0.05）。多因素分析显示,女性、年龄>45岁、患慢性病、日常生活习惯是影响中老年口腔健康和生活质量的独立危险因素（P<0.05或P<0.01）。结论 口腔健康作为全身健康的基础,其影响因素多种多样,通过控制干预主要影响因素来提高社区口腔健康和相关生活质量,以改善社区居民生活幸福值。

Objective By focusing on and tracking the impact of oral health problems of middle-aged and elderly people on the quality of life,the relevant influencing factors and relationships of oral health were systematically sorted out to provide a research basis for the development of oral health and related quality of life of such people．Methods A total of 266 middle-aged and elderly people were randomly selected from October 2022 to May 2023 to participate in the survey,and the sociological characteristics,daily oral health care behaviors and physical health status of this population were collected according to the “etiological chain”,so as to analyze and evaluate the quality of life related to the oral health of middle-aged and elderly people．Results The 266 middle-aged and elderly people had a mean score of（30.69±8.98）for general knowledge and behavioral scores of oral health,a mean score of（8.59±3.68）for oral health assessment,a total score of（25.65±8.10）for oral health-related quality of life GOHAI．The univariate analysis showed that demographic characteristics,general body health state,oral health cognition and behavior and oral health state were closely associated with the GOHAI score related to the oral health associated quality of life in the middle-aged and elderly people（P<0.05）．The multivariate analysis indicated that female,age >45 years old,presence of chronic diseases and daily living habits were indepdent risk factors of the oral health and quality of life of the middle-aged and elderly（P<0.05）．Conclusions Oral health,as the basis of systemic health,has various influencing factors,by controlling the main influencing factors can improve the community oral health and related quality of life,and improve the happiness of community residents．
