集団検診において歯周疾患の早期発見のために臨床検査試験紙 (Hema-Combistix) を応用した結果について

The gingival bleeding offers an important part in the conditions or diagnosis of periodontal disease.We paid attention to Hema-Combistix which have been used as a clinical judging paper in urinalysis.The purpose of this paper was to examine if salivary occult blood teat by Hema-Combistix was useful to the detection of periodontal disease in early stage.The results obtained from this study with 1, 241 students of a senior high school examined are as follows:1. Positive group to the salivary occult blood test was 37%.The reaction showed by the positive subjects was classified into three degrees, slight (81%), moderate (16%), and severe (3%).2. There was a tendency toward an increase on PMA index number with increasing degree of the salivary occult blood test.3. A group of subjects with negative reaction to salivary occult blood test but with complaint of gingival bleeding was 30%.Avarages of PMA index number of the groups were 7.6% and 10.9%, respectively.4. There were statistically no differences between positive group and negative group to the salivary occult blood test, on numbers of filled teeth, pH of saliva, protein content in saliva and glucose content in saliva.From these results, it is considered that the salivary inspection method by Hema-Combistix paper serves as a convenient test for finding the gingival bleeding or an early stage of periodontal disease.
