补充数字内容可在文本中本研究的目的是调查在日本的老年人群的牙齿状况和合并症之间的相关性。在这项研究中使用的数据库，从12个养老院在日本获得的数据。研究期间为2014年1月至2015年12月，分析中包括有牙科和其他医疗记录的老年人。采用线性回归模型分析牙齿状况、合并症和其他社会人口统计学/临床背景之间的单变量和多变量相关性。在排除数据缺失的个体后，289名老年人（107名男性和182名女性;平均年龄85岁）被纳入分析。这些人平均有11.6颗牙齿，随着年龄的增长，牙齿数量减少（P <0.001）。 平均蛀牙数为1.4颗。共有116例受试者（40.1%）患有痴呆。在合并症方面，痴呆与现有牙齿数量无显著相关性（P = 0.56），但与龋齿数量相关（P = 0.018）。 在多变量回归分析中调整混杂变量后也观察到这种关联（P = 0.030）。 蛀牙的数量与痴呆症有关。虽然无法从这些观察结果中推断出因果关系，但研究结果表明，牙齿健康可能是即将发生痴呆症的标志，也可能是老年人总体健康状况的标志。额外的纵向研究是非常可取的，以了解牙齿条件和合并症之间的因果关系。
Supplemental Digital Content is available in the text The purpose of this study was to investigate the correlation between dental conditions and comorbidities in an elderly population in Japan. A database constructed using data obtained from 12 nursing homes in Japan was used in this study. The study period ranged from January 2014 to December 2015, and elderly individuals with dental and other medical records were included in the analysis. Linear regression models were used to analyze univariate and multivariate correlation between dental conditions, comorbidities, and other sociodemographic/clinical backgrounds. After excluding individuals with missing data, 289 elderly individuals (107 men and 182 women; mean age, 85 years) were included in the analysis. These individuals had an average of 11.6 teeth, and the number decreased with older age (P < .001). The average number of decayed teeth was 1.4. A total of 116 subjects (40.1%) had dementia. In terms of comorbidities, dementia was not significantly associated with the number of present teeth (P = .56), but it was associated with the number of decayed teeth (P = .018). This association was also observed after adjusting for confounding variables in the multivariate regression analysis (P = .030). The number of decayed teeth was associated with dementia. While causality cannot be inferred from these observational results, the findings indicate that dental health could represent a marker of impending dementia, and probably represent a marker of general health status in the elderly population. Additional longitudinal studies are highly desirable to understand the causal relationships between dental conditions and comorbidities.
