目的许多老年人失去牙齿。然而，很少有研究研究在调整了全身因素后，剩余牙齿的数量或咬合支撑量对老年人发生的牙齿脱落更重要。这项研究的目的是在6年的时间里全面调查与牙齿脱落相关的因素，包括在70岁和80岁的社区居住的日本人的咬合支持。方法队列研究包括70岁组296人和80岁组232人。记录所有参与者在基线和6年后的牙齿数量，并根据牙齿脱落的数量(0或4或更多)将参与者分为两组。咬合支持根据后牙合支持分为三组。对患者的平均探诊深度、刷牙习惯、牙科检查频度、文化程度、经济状况及全身因素(颈动脉粥样硬化、高血压、糖尿病、血脂异常、认知功能、吸烟习惯)进行评估。采用多因素Logistic回归分析牙齿缺失与咬合支持、全身因素的关系。结果Logistic回归分析显示，平均探诊窝深(优势比[OR]=5.70，95%可信区间[CI]=2.70~12.04，P&t；01)和后牙合支持(参考=Eichner A类；Eichner B1-3，OR=4.33，95%CI=1.54~12.17，P<；01；Eichner B4或C，OR=6.16，95%CI=1.17~32.44，P=0.03)与4颗以上牙齿缺失显著相关。结论这项研究表明，年龄本身并不是社区居住的日本老年人多发性牙齿缺失的预测因素。深度平均探测袋深度和缺乏后牙合支持与失去四颗或更多牙齿显著相关。
Objectives Many older people lose their teeth. However, few studies have examined whether the number of remaining teeth or the amount of occlusal support is more important for tooth loss that occurs in older age after adjusting for systemic factors. The purpose of this study was to investigate comprehensively the factors related to tooth loss over a period of 6 years, including occlusal support in 70- and 80-year-old community-dwelling Japanese people. Methods This cohort study included 296 participants in the 70-year-old group and 232 in the 80-year-old group. The number of teeth of all participants was recorded at baseline and after 6 years, and the participants were divided into two groups according to the number of teeth lost (0 or 4 or more). Occlusal support was classified into three groups based on posterior occlusal support. Mean probing pocket depth, tooth brushing habits, frequency of dental check-ups, education level, economic status and systemic factors (carotid atherosclerosis, hypertension, diabetes mellitus, dyslipidemia, cognitive function and smoking habits) were evaluated. Multiple logistic regression analysis was performed to investigate the relationship of tooth loss with occlusal support and systemic factors. Results Logistic regression analysis revealed that mean probing pocket depth (odds ratio [OR] = 5.70, 95% confidence interval [CI] = 2.70-12.04, P < .01) and posterior occlusal support (reference = Eichner class A; Eichner B1-3, OR = 4.33, 95% CI = 1.54-12.17, P < .01; Eichner B4 or C, OR = 6.16, 95% CI = 1.17-32.44, P = .03) were associated significantly with the loss of four or more teeth. Conclusions This study revealed that age itself is not a predictor of multiple tooth loss in community-dwelling older Japanese people. Deep mean probing pocket depth and a lack of posterior occlusal support were significantly associated with the loss of four or more teeth.
