The oral cavity is colonized by various groups of microorganisms. Toothbrushing is a common method of maintaining oral hygiene and, upon regular use, can become heavily contaminated with microorganisms. To avoid contamination of the toothbrush with microorganisms from the external environment, toothbrushes can be protected by a protective cap, the significance of which is unknown.
To assess the microbial contamination of the toothbrush with and without a protective cap and to find the significance of the same against microbial contamination.
An study was conducted in the Faculty of Dental Sciences, Sri Ramachandra University. A total of 40 toothbrushes were distributed among dental students aged 18-25 years; 20 were protected by a cap, 20 were unprotected, and instructions were given to recap the toothbrush after brushing. After 1 month of regular usage, toothbrushes were collected, and organisms were identified based on Gram's reaction followed by a biochemical test.
From the study conducted, it is evident that the microbial contamination of the unprotected toothbrush is higher than that of the toothbrushes that were protected with a cover.

口腔中定植着各类微生物。刷牙是保持口腔卫生的常见方法，长期使用后，牙刷会被微生物严重污染。为避免牙刷受到外部环境微生物的污染，可使用保护帽来保护牙刷，但其意义尚不清楚。
评估有保护帽和无保护帽牙刷的微生物污染情况，并探究其对微生物污染的意义。
在斯里兰卡拉马钱德拉大学牙科学院开展了一项研究。共向18 - 25岁的牙科学生分发了40支牙刷；20支配有保护帽，20支无保护帽，并指导学生刷牙后给牙刷戴上保护帽。定期使用1个月后，收集牙刷，并根据革兰氏反应及后续生化试验鉴定微生物。
从开展的研究来看，很明显无保护帽牙刷的微生物污染程度高于有保护帽的牙刷。
