An automatic oral cleaning apparatus for hospitalized handicapped patients was developed and its clinical application was investigated. The apparatus consisted of an air-driven vibratory toothbrush, an oral irrigator and an aspirator which were supported by a two-jointed arm attached to the side of the mobile body. Two Collis' curve brush tip were connected, back to back, as a brush for this apparatus.Twelve dental students and 17 hospitalized patients of progressive muscular dystrophy were the subjects of this investigation. The plaque score index used was modigication of Harrap's and Cohen's method. The index of experimentally accumulated plaque was 2.1 in the student group and decreased to 1.3 after 3 minutes use of this apparatus. Experimental accumulation of plaque was not adopted on the patient group. The initial plaque score of 3.8 in patient group decreased to 2.1 after the use of the apparatus.The proximal surface of teeth and abnormal arrangement teeth were the most difficult sites to remove plaque by the apparatus.

介绍了一种用于住院残疾人口腔自动清洁装置的研制及临床应用情况。该装置由一个气动振动牙刷、一个口腔冲洗器和一个吸引器组成，它们由一个连接在移动的主体侧面的双关节臂支撑。本研究以12名牙科学生和17名住院的进行性肌营养不良症患者为研究对象。采用改良Harrap和Cohen法的菌斑积分指数。学生组的实验累积菌斑指数为2.1，使用该装置3分钟后降低至1.3。患者组不采用实验性斑块堆积法。患者组的初始菌斑评分为3.8分，使用该器械后菌斑评分降至2.1分，牙近侧面和排列异常牙是最难清除菌斑的部位。
