Abstract
The experimental subjects comprised 51 men and 81 women. All were outpatients visiting from 1973 to 1978 at periodontal clinic of Dental Hospital, Iwate Medical University, they were selected for this study on the basis of a standard.
In order to compare clinical finding with the histological picture as well as the comparison between each clinical appearance in the periodontal disease, the gingival biopsies from the anterior portion of the patients of the chronic marginal periodontitis were examined on the basis of periodontal disease index.
The results are as follows.
1. A correlation between the clinical appearances of inflammation and the histological findings of gingival inflammation was found in about two thirds of the cases, particularly there was a correlation more in interdental areas than in marginal areas. There was also a clear correlation between the two.
2. As regard to periodontal pocket and the histological findings of the gingival inflammation, a correlation was found in the interdental areas in male, but not found clearly in other areas.
A correlation was rather observed between periodontal pocket and the clinical appearance of gingival inflammation.
3. A correlation was neither found between bone resorption and the histological finding of gingival inflammation nor found between bone resorption and clinical signs.
4. Sex difference in periodontal pocket and bone resorption was observed. Periodontal pocket depth and bone resorption were highly showed more in male than in female.
Age difference in periodontal pocket depth and bone resorption was observed, particularly it was significant between a twenty-age and a thirty-age.
