In the treatment of this autoimmune disease, cyclosporin A (CyA) is used. Gingival hyperplasia (GH) is one of the important side effects that have been observed in some of the patients. We aimed to evaluate the CyA-induced gingival hyperplasia in BD patients. There were 3 study groups, each having 5 patients. In the first group displaying GH, mast cells were located between epithelial cells and in the connective tissue. Mast cell granules were in crystalline form and electron-dense cored form. Fibroblasts and plasma cells were present in the connective tissue. The second group did not display GH and the mast cells were similar to those in the first group. The third group, was the control group, in which the mast cells were located between the epithelial cells and connective tissue. Mast cell granules were in electron-dense cored form. We concluded that the development of CyA-induced gingival hyperplasia is determined mainly by individual sensitivity to CyA, because although both test groups which received CyA showed an increased number and activity of fibroblasts, only one group of patients developed GH.</p>","PeriodicalId":77213,"journal":{"name":"Journal of Marmara University Dental Faculty","volume":"1 4","pages":"290-6"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20503427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many factors have been reported as the cause of these distortion phenomena, studies of marginal distortion associated with firing metal-ceramic restorations have yielded mixed results. The effect of firing cycles on distortion of a metal-ceramic coping was examined on 0.5 mm thick palladium-copper copings with shoulder marginal finish lines. It was found that the distortion produced in the first stage of firing was greater than at other stages. The marginal distortion seen on the porcelain veneered margin was not significantly different from the distortion on the non-veneered margin. These two results demonstrate that thermal contraction stresses due to porcelain contraction are probably not the primary cause of coping distortion. The internal surfaces of the copings were examined for contamination with porcelain particles and porcelain contamination was detected with an energy dispersive spectrometer analysis. The distortion produced during the porcelain veneering procedure was due to porcelain contamination on the internal surfaces of the copings. A convenient method is necessary to remove porcelain from the internal surfaces of completed restorations.</p>","PeriodicalId":77213,"journal":{"name":"Journal of Marmara University Dental Faculty","volume":"1 4","pages":"285-9"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20503426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
