Tongue scraping and brushing have been appreciated for hundreds of years but are still appreciated or used by the public. Scientific evidence has validated the need to practice habitual and tongue cleaning as part of daily home oral hygiene procedures.
To assess and compare the effect of tongue scraping and tongue brushing on oral Mutans streptococci level.
A total of 20 healthy subjects aged 14 to 15 years were randomly selected. Flat plastic tongue scraper and Nylon multitufted small headed toothbrush are the two tongue cleaning devise used. Unstimulated salivary samples were obtained at 4 intervals from each individual. Salivary samples were inoculated on Mitis Salivary Agar Plate and Sorbital Broth was used for identification of Mutans streptococci group.
Paired and unpaired 't' test were employed. Reduiction in the Mutans streptococci level from 48.4 × 10(4) CFU and 38.3 × 10(4) CFU at baseline in tongue scraping and tongue brushing group respectively to 0.34 × 10(4) and 0.39 × 104 CFU after 7th day.
Both tongue coating removal methods evaluated were efficient in reducing mutans streptococci level. This implies that physical removal of the coating on the dorsum of the tongue is important and not the method used for the same.
刮舌和刷舌已被人们认可数百年，但至今仍为公众所接受或使用。科学证据证实，日常家庭口腔卫生程序中应养成清洁舌头的习惯。
评估并比较刮舌和刷舌对口腔变形链球菌水平的影响。
随机选取20名年龄在14至15岁的健康受试者。使用的两种舌清洁工具分别为扁平塑料刮舌器和尼龙多头小头牙刷。从每位受试者身上每隔一段时间采集一次非刺激性唾液样本。将唾液样本接种在米氏唾液琼脂平板上，并用山梨醇肉汤鉴定变形链球菌组。
采用配对和非配对“t”检验。刮舌组和刷舌组的变形链球菌水平在基线时分别为48.4×10⁴CFU和38.3×10⁴CFU，第7天后分别降至0.34×10⁴CFU和0.39×10⁴CFU。
所评估的两种去除舌苔的方法在降低变形链球菌水平方面均有效。这意味着从舌背物理去除舌苔很重要，而不是使用何种方法。
