Oral health status may be associated with dementia, which in turn results in higher medical costs among older people.
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.
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.
Oral health status was associated with the medical costs of dementia. Preventing tooth loss and maintaining periodontal health may contribute to controlling dementia costs.
口腔健康状况可能与痴呆有关，而痴呆又会导致老年人的医疗费用增加。
本研究纳入了 4275 名老年人。以痴呆的医疗费用为因变量，以牙齿数量、社区牙周指数（CPI）和其他因素为自变量，构建了广义线性模型。
在排除其他混杂因素后，牙齿数量少或牙周状况差的个体痴呆的医疗费用比明显更高。与≥20 颗牙齿的个体相比，≤9 颗牙齿的个体痴呆的调整后医疗费用比为 4.13（95%置信区间[CI]：1.79-9.56）；与个人 CPI 代码为 0-2 的个体相比，个人 CPI 代码为 4 的个体痴呆的调整后医疗费用比为 3.48（95%CI：1.71-7.08）。
口腔健康状况与痴呆的医疗费用有关。预防牙齿脱落和保持牙周健康可能有助于控制痴呆的成本。
