Abstract：
BACKGROUND: The number of older individuals with mild cognitive impairment and neurocognitive diseases is increasing, which may rapidly deteriorate oral health and Quality of life. Therefore, removing dental biofilm is essential for maintaining good oral health. The present study aimed to investigate whether introducing a powered toothbrush reduces the presence of dental plaque, bleeding on probing, and periodontal pockets ≥4 mm, leading to maintained or improved oral health and improved Quality of life in a group of older individuals with mild cognitive impairment.
METHODS: Two hundred and thirteen individuals aged 55 or older living without official home care with a Mini-Mental State Examination (MMSE) score between 20 and 28 and a history of memory problems in the previous 6 months were recruited and screened for the study. The individuals received a powered toothbrush and thorough instructions on how to use it. Clinical oral examinations, Quality of life examinations, and MMSE tests were conducted at baseline, 6, 12, and 24 months. The intervention group was compared to control groups at baseline and 24-month examination. It was divided into an MMSE high group with a score of more than 26 and an MMSE low group with a score of 26 and lower or decreasing two steps or more for 12 months.
RESULTS: PI, BOP, and PPD≥4 mm improved continuously in both MMSE groups during the 24 months of the study. The values for QoL-AD deteriorated over time, while the oral health-related Quality of life did not show any statistically significant changes.
CONCLUSIONS: Introducing a powered toothbrush improved PI, BOP, and PPD≥4 mm over 24 months, even among individuals with low or declining MMSE scores. Improved oral health is associated with a preserved OHR-QoL.

摘要：
背景：患有轻度认知障碍和神经认知疾病的老年人数量正在增加，这可能会迅速恶化口腔健康和生活质量。因此,去除牙齿生物膜对于保持良好的口腔健康至关重要。本研究旨在调查是否引入电动牙刷减少牙菌斑的存在，探查时出血,和牙周袋≥4毫米，在一组患有轻度认知障碍的老年人中，可维持或改善口腔健康并提高生活质量。
方法：招募了两百十三名年龄在55岁或以上的人，他们没有正式的家庭护理，他们的迷你精神状态检查（MMSE）评分在20到28之间，并且在过去的6个月中有记忆问题史被纳入研究并筛选。这些人收到了电动牙刷和如何使用它的详细说明。临床口腔检查，生活质量检查，和MMSE测试在基线进行，6、12和24个月。在基线和24个月检查时，将干预组与对照组进行比较。将其分为MMSE高组，得分为26分以上，MMSE低组，得分为26分，降低或降低两个步骤或更多，持续12个月。
结果：PI，防喷器,在研究的24个月期间，两个MMSE组的PPD≥4mm持续改善。QoL-AD的值随着时间的推移而恶化，而与口腔健康相关的生活质量没有任何统计学上的显著变化。
结论：介绍一种改进PI的电动牙刷，防喷器,PPD≥4mm超过24个月，甚至在MMSE得分较低或下降的个体中。改善的口腔健康与保留的OHR-QoL相关。
