Objective:

Oral health status may be associated with dementia, which in turn results in higher medical costs among older people.

Methods:

This STUDY enrolled 4,275 older individuals. Generalized linear models were constructed with the medical costs of dementia as the dependent variable, and number of teeth, Community Periodontal Index (CPI), and other factors as independent variables.

Results:

Individuals with fewer teeth or with poor periodontal condition had significantly higher medical costs ratios for dementia independent of other confounding variables. The adjusted medical costs ratios of dementia were 4.13 (95% CI [confidence interval]; 1.79–9.56) for those with ≤9 teeth compared with those with ≥20 teeth and 3.48 (95% CI; 1.71–7.08) for those with personal CPI code 4 compared with those with personal CPI code 0–2.

Conclusions:

Oral health status was associated with the medical costs of dementia. Preventing tooth loss and maintaining periodontal health may contribute to controlling dementia costs.

口腔健康与痴呆症医疗费用之间的关联：日本老年人的纵向研究

客观的：

口腔健康状况可能与痴呆症有关，这反过来导致老年人的医疗费用更高。

方法：

这项研究招募了4,275名年龄较大的个体。以痴呆症的医疗费用为因变量，以牙齿数目，社区牙周指数（CPI）和其他因素作为自变量来构建广义线性模型。

结果：

牙齿少或牙周病状况较差的个体，与其他混杂变量无关，痴呆症的医疗费用比率明显更高。≤9颗牙齿的人的痴呆症调整后的医疗费用比率为4.13（95％CI [置信区间]； 1.79–9.56），而≥20牙齿的人则为3.48（95％CI； 1.71–7.08） CPI代码4与个人CPI代码0–2相比。

结论：

口腔健康状况与痴呆症的医疗费用有关。预防牙齿脱落和保持牙周健康可能有助于控制痴呆症的成本。
