| Research Abstract |
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.
