The study aimed to investigate how the objective use of a powered toothbrush in frequency and duration affects plaque index, bleeding on probing, and periodontal pocket depth ≥ 4 mm in elderly individuals with MCI. A second aim was to compare the objective results with the participants' self-estimated brush use.
Objective brush usage data was extracted from the participants' powered toothbrushes and related to the oral health variables plaque index, bleeding on probing, and periodontal pocket depth ≥ 4 mm. Furthermore, the objective usage data was compared with the participants' self-reported brush usage reported in a questionnaire at baseline and 6- and 12-month examination.
Out of a screened sample of 213 individuals, 170 fulfilled the 12-month visit. The principal findings are that despite the objective values registered for frequency and duration being lower than the recommended and less than the instructed, using powered toothbrushes after instruction and information led to improved values for PI, BOP, and PPD ≥ 4 mm in the group of elderly with MIC.
Despite lower brush frequency and duration than the generally recommended, using a powered toothbrush improved oral health. The objective brush data recorded from the powered toothbrush correlates poorly with the self-estimated brush use.
Using objective brush data can become one of the factors in the collaboration to preserve and improve oral health in older people with mild cognitive impairment.

本研究旨在探讨电动牙刷在使用频率和时长方面的客观使用情况如何影响轻度认知障碍（MCI）老年患者的菌斑指数、探诊出血和牙周袋深度≥4mm。第二个目的是将客观结果与参与者自我估计的刷牙使用情况进行比较。
从参与者的电动牙刷中提取客观刷牙使用数据，并将其与菌斑指数、探诊出血和牙周袋深度≥4mm 等口腔健康变量相关联。此外，将客观使用数据与参与者在基线和 6 个月及 12 个月检查时在问卷中报告的自我报告刷牙使用情况进行比较。
在筛选出的 213 名个体中，有 170 名完成了 12 个月的随访。主要发现是，尽管记录的频率和时长的客观值低于推荐值且少于指导值，但在指导和信息后使用电动牙刷可改善 MCI 老年组的 PI、BOP 和 PPD≥4mm 的值。
尽管刷牙频率和时长低于一般推荐值，但使用电动牙刷可改善口腔健康。从电动牙刷中记录的客观刷牙数据与自我估计的刷牙使用情况相关性较差。
使用客观刷牙数据可能成为协作以维持和改善轻度认知障碍老年人口腔健康的因素之一。
