Abstract
In March 1987, we investigated the quality of oral hygiene, and the incidence of dental caries and periodontal diseases in 140 severely handicapped patients who had been hospitalized in two national sanatorium. All of the patients had participated under the Matsumoto Dental College Hospital Periodic Dental Check-up System for five years.
The results were as follows;
1. The teeth of all the subjects had been brushed by the sanatorium nursing staff twice per day. The prevailing brushing technique was the horizontal method.
2.37.5% of the subjects showed complete adaptability to the tooth brushing by the nursing staff. However,2.1% showed no adaptability whatsoever.
3. The mean value of the OHI-S was 1.53. The labial surfaces of the maxillary anterior teeth showed the lowest OHI-S value, while the mandibular left posterior teeth showed the highest.
4. The DMF-T was estimated to be 12.51 (DMFT ratio=48.2%). The average D-T was 2.07±4.03, and the average F-T was 8.43±7.22.
5.19.3% of the patients were diagnosed with gingival hyperplasia, and 10.7%had local gingival recessions.
1) Of the patients who had taken Phenytoin daily,35.5 % were diagnosed with hyperplasia.
2) Most local gingival recessions were found on the labial gingiva of the mandibular anterior teeth. A relationship was determined to exist the local recession and the horizontal brushing method.
6.89.2% of the patients suffered from periodontal diseases. On examination using the Community Periodontal Index of Treatment Needs (CPITN), we found that 30.0% of the subjects showed bleeding by probing only (code 1),32.3% had supra or sub-gingival calculus (code 2),23.1% had shallow pockets of 4 to 5 mm (code 3), and 3.9% had deep pockets of more than 6 mm (code 4).
