The effectiveness of an electric toothbrush (Rota-dent), which in design and mode of action resembles the rotating instruments used by professionals in tooth cleaning, was assessed. 40 adult periodontal patients were divided into 2 groups matched with regard to oral cleanliness: an electric toothbrush group (EB) comprising 20 patients who received an electric toothbrush as well as instruction in it's use by a dental hygienist; a control group (CO) comprising 20 patients who were provided with an oral hygiene kit containing a conventional toothbrush, an interspace brush, toothpicks, disclosing tablets and a lighted mouth mirror and who received the oral hygiene instruction by means of a self-teaching manual. All patients received professional mechanical tooth cleaning 1 week prior to the instruction. At a 3-week follow-up session, additional instruction was given by a dental hygienist according to needs. The presence or absence of dento-gingival plaque after disclosing with the Plak-lite system and gingival bleeding by gentle probing was recorded on 4 tooth surfaces of all teeth, initially and after 3 months. The findings showed a similar improvement in the status of oral hygiene in both groups, indicating that in the hands of the patients, the electric toothbrush was just as effective as the comprehensive oral hygiene kit.
对一种电动牙刷（Rota-dent）的效果进行了评估，该电动牙刷在设计和作用方式上类似于专业人员用于牙齿清洁的旋转器械。40名成年牙周病患者按口腔清洁程度分为两组：电动牙刷组（EB），包括20名患者，他们收到了一支电动牙刷，并由一名牙科保健员指导如何使用；对照组（CO），包括20名患者，他们得到了一套口腔卫生用品套装，其中包含一支传统牙刷、一支牙缝刷、牙签、示踪片和一面带照明的口腔镜，并通过一本自学手册接受口腔卫生指导。所有患者在接受指导前1周都接受了专业的机械牙齿清洁。在3周的随访期间，牙科保健员根据需要提供了额外的指导。使用Plak-lite系统进行示踪后，记录所有牙齿的4个牙面有无牙菌斑以及轻轻探查时牙龈出血情况，分别在初始时和3个月后进行记录。结果显示两组的口腔卫生状况改善程度相似，这表明在患者手中，电动牙刷与综合口腔卫生用品套装的效果一样好。
