The relationship between oral health status and bone mineral density has been poorly elucidated. We conducted a cross-sectional study to examine the relationship between oral health status and bone mineral density with data from healthy community-dwelling elderly individuals in Ohnan-cho, Shimane Japan who were recruited in 2019 for the Shimane Center for Community-Based Health Research and Education (CoHRE) study. The study included 702 participants (306 men and 396 women). The median age, bone mineral density, and number of remaining teeth were 69.0 years, 86.2%, and 26.0, respectively. The two groups (Low teeth group and High teeth group) showed significant differences in age, hemoglobin A1c (HbA1c) level, and masticatory function in men ( < 0.05). In women, age, number of untreated teeth, and masticatory function were significantly different ( < 0.05). The odds ratio of propensity score analysis for the association between the number of remaining teeth and bone mineral density was 27.7 (95% confidence interval: 1.86-414.9, < 0.05). The number of remaining teeth could be associated with bone mineral density in the healthy elderly women, and no significant association was observed in men. Number of remaining teeth and bone mineral density may be interrelated, and oral care by dentists/dental hygienists may play an important role in maintaining bone mineral density in elderly women.
口腔健康状况与骨密度之间的关系尚未得到充分阐明。我们进行了一项横断面研究，利用2019年为岛根县社区健康研究与教育中心（CoHRE）研究招募的日本岛根县大南町健康社区老年人的数据，来研究口腔健康状况与骨密度之间的关系。该研究包括702名参与者（306名男性和396名女性）。年龄中位数、骨密度和剩余牙齿数量分别为69.0岁、86.2%和26.0颗。两组（低牙组和高牙组）在男性的年龄、糖化血红蛋白（HbA1c）水平和咀嚼功能方面存在显著差异（<0.05）。在女性中，年龄、未治疗牙齿数量和咀嚼功能存在显著差异（<0.05）。剩余牙齿数量与骨密度之间关联的倾向得分分析的比值比为27.7（95%置信区间：1.86 - 414.9，<0.05）。在健康老年女性中，剩余牙齿数量可能与骨密度有关，而在男性中未观察到显著关联。剩余牙齿数量和骨密度可能相互关联，牙医/口腔保健员的口腔护理可能在维持老年女性骨密度方面发挥重要作用。
