| Abstract | ||
| Background: This study evaluate the immunohistochemical expression profile of transforming growth factor beta-1 in inflamed gingival tissue of patients with gingivitis and chronic periodontitis compared to healthy subjects and, determine the correlation between this cytokine and the clinical periodontal parameters, intensity of inflammation and chronic periodontitis severity. Materials and methods: Gingival tissue specimens were taken from 23 chronic periodontitis patients, 20 gingivitis patients and 20 periodontally healthy subjects. The periodontal status was evaluated by dichotomous measurements of the clinical periodontal parameters (PLI, GI, BOP, PPD, CAL). The gingival specimens were fixed immediately in 10% formalin and processed routinely into paraffin blocks for further immunohistochemical analysis. Results: A highly significant statistical difference was observed between the study groups regarding the PLI ,GI ,the percentage of bleeding on probing sites and the intensity of inflammation .TGF-β1 expression profile statistical analysis showed a high statistical significant difference among the study groups , A highly significant statistical difference was found between the PPD Scores while a significant statistical difference was revealed among the CAL Scores when the expression profile of TGF-β1 was compared.TGF-β1 was positively correlated with the clinical periodontal parameters (PLI, GI, and BOP) as well as with the intensity of inflammation in the three study groups. In chronic periodontitis group a highly significant positive linear correlation between the PPD and CAL with the TGF-β1 expression profile. Conclusions: TGF-β1 expression profile showed variations as the destructive character of the periodontal disease changed. Therefore, it could be proposed that TGF-β1 might contribute both to inflammatory regulation and remodeling events during periodontal disease | ||
