前言：牙周病与痴呆症的关系已有报道。去看牙医以保持健康的牙周组织是很重要的。很少有关于看牙医和痴呆症风险之间的联系的研究报道。这项研究基于医疗保险索赔数据，考察了老年人对牙科保健的使用与痴呆症发病率的关系。材料和方法：我们调查了31775名75岁或80岁的人。牙齿使用率从2014年4月至2015年3月的医疗保险索赔数据中获得。在4年随访期内首次发生痴呆症医疗费用的月份被定义为痴呆症发病月份。结果：在牙科就诊类型方面，接受牙周治疗的痴呆症患者调整后的总体痴呆风险比(0.89：95%CI，0.81~0.98)显著低于未接受牙周治疗的患者(P<0.05)。在牙周治疗天数方面，接受≥治疗5天的受试者患全面性痴呆、阿尔茨海默病和血管性痴呆的调整后HR值分别为0.84(95%CI，0.75~0.94)、0.88(95%CI，0.77~1.00)和0.82(95%CI，0.69~0.99)，差异有统计学意义。定期看牙医以治疗或预防牙周病可能对预防痴呆症很重要。
Introduction:A relationship between periodontal disease and dementia has been reported. It is important to visit a dentist to maintain healthy periodontal tissue. Few studies have been reported on the association between dental visits and the risk of dementia. This study examined the relationship between the use of dental care among older people and the incidence of dementia based on health insurance claims data.Materials and Methods:We targeted 31,775 people aged 75 or 80 years. Dental utilization was obtained from the health insurance claims data from April 2014 to March 2015. The month when dementia medical costs were first incurred during the 4-year follow-up period was defined as the dementia onset month. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of the incidence of dementia for the use of dental care.Results:Regarding the type of dental visit, the adjusted HR of overall dementia was significantly lower (0.89: 95% CI, 0.81–0.98) in those who received periodontal treatment compared with those who did not receive any dental treatment. Regarding the days of periodontal treatment, participants with ≥5 days had significantly lower adjusted HRs for overall dementia, Alzheimer’s disease, and vascular dementia than those with 0 days, and the adjusted HRs were 0.84 (95% CI, 0.75–0.94), 0.88 (95% CI, 0.77–1.00), and 0.82 (95% CI, 0.69–0.99), respectively.Conclusion:Individuals who received periodontal treatment on many days had a low risk of dementia. Regular dental visits to treat or prevent periodontal disease may be important to prevent dementia.
