Oral hygiene influences taste, affecting appetite and nutrition in older adults. However, the impact of self-administered tongue brushing on their taste perceptions was unclear. This pilot study (N = 44) was aimed to observe the changes in taste thresholds using Filter Paper Disc after tongue brushing in Thai older adults. Based on the results, continuous tongue brushing for 3 months reduced tongue coat (p < 0.01) and improved subjective taste in 74% of participants. Sweet and salty recognition thresholds were reduced in both anterior and posterior tongue, while sour and bitter thresholds were reduced only in posterior tongue. No changes in umami (savory) were observed. Daily brushing was more effective than weekly brushing in improving the sweet and bitter tastes. The data suggested that tongue brushing could improve perception of multiple tastes and daily tongue brushing was recommended as routine personal care for older adults. This study supports further investigation in a randomized-controlled setting.
口腔卫生会影响味觉，进而影响老年人的食欲和营养状况。然而，自行进行舌部刷牙对老年人味觉感知的影响尚不清楚。这项试点研究（N = 44）旨在观察泰国老年人在舌部刷牙后使用滤纸圆盘法测定的味觉阈值变化。根据研究结果，持续进行3个月的舌部刷牙可减少舌苔（p < 0.01），74%的参与者主观味觉得到改善。舌前部和后部的甜味和咸味识别阈值均降低，而酸味和苦味阈值仅在舌后部降低。未观察到鲜味（美味）的变化。每日刷牙在改善甜味和苦味方面比每周刷牙更有效。数据表明，舌部刷牙可改善多种味觉的感知，建议将每日舌部刷牙作为老年人的日常个人护理措施。本研究支持在随机对照环境中进行进一步调查。
