Abstract：
As we age, maintaining good oral health becomes increasingly crucial for performing daily tasks. Age-related physiological decline can disrupt various biological systems, causing a significant challenge for geriatric dentistry. A systematic review of the literature using six different electronic databases was conducted to investigate the relationship between oral health indicators and bone mineral density disorders in older adults. The study is registered as a priori protocol on PROSPERO (CRD42023403340). A minimum age of 60 years was the main inclusion criterion for all original research articles. Two independent researchers assessed the eligibility of 19,362 records against the inclusion criteria and found 12 articles fitting the eligibility requirements. Five different indicators of poor oral health [number of teeth, periodontal disease, general oral health (dental caries prevalence and dental treatment needs), masticatory function, and occlusal force)] were found related to three outcomes linked to bone mineral density disorders (osteoporosis, fractures, and decreased bone mineral density), regardless of the adopted assessment tools. The number of teeth was negatively associated with fractures and a decreased bone mineral density, while periodontal disease was positively associated with osteoporosis and a decreased bone mineral density. Masticatory function was associated only with osteoporosis, while general oral health was associated only with fractures and occlusal force only with bone mineral density. The oral health indicator most frequently associated with outcomes linked to bone mineral density disorders was the number of teeth. The present findings could help to assess the contribution of each oral health indicator to the development of bone mineral density disorders in older age.
摘要：
随着年龄的增长,保持良好的口腔健康对于执行日常任务变得越来越重要。与年龄相关的生理衰退会破坏各种生物系统，对老年牙科造成重大挑战。使用六个不同的电子数据库对文献进行了系统回顾，以调查老年人口腔健康指标与骨密度障碍之间的关系。该研究在PROSPERO(CRD42023403340)上注册为先验协议。60岁的最低年龄是所有原始研究文章的主要纳入标准。两名独立研究人员根据纳入标准评估了19,362条记录的资格，发现12篇文章符合资格要求。口腔健康不良的五个不同指标[牙齿数量，牙周病,一般口腔健康（龋齿患病率和牙科治疗需求），咀嚼功能,和咬合力)]被发现与骨密度障碍(骨质疏松症，骨折,和骨矿物质密度降低)，无论采用何种评估工具。牙齿数量与骨折和骨密度降低呈负相关，而牙周病与骨质疏松和骨密度降低呈正相关。咀嚼功能仅与骨质疏松症有关，而一般的口腔健康仅与骨折有关，而咬合力仅与骨矿物质密度有关。与骨矿物质密度障碍相关的结果最常见的口腔健康指标是牙齿数量。目前的发现可能有助于评估每个口腔健康指标对老年人骨矿物质密度障碍发展的贡献。
