Background & Aim: Apoptosis is an evolutionary form of physiological cell death. Although numerous investigations have suggested that apoptosis is involved in the pathogenesis of diseases such as Rheumatoid Arthritis, Neurodegenerative diseases and cancer, the effect of apoptosis in periodontal disease still unknown. Therefore, we studied the apoptotic events in periodontally diseased gingival tissue.

Method & Materials: Gingival tissue biopsies from 15 patients with aggressive periodontitis, 15 patients with sever chronic periodontitis, and 15 healthy control, were obtained. Criteria for patients’ inclusion matched with classification of periodontal diseases. The control group included subjects with no prior history of periodontal diseases. The expression of Fas and Bcl-2 receptor were determined by Immunohistochemistry technique.

Results: Positive staining for Fas and Bc-2 receptor in sever chronic periodontitis was observed. (3.86±2.69 %) (36.57±6.24%). In aggressive periodontitis, positive staining for Fas and Bcl-2 receptor was observed (37.73%) (68.34 %). The differences between groups were significant (Mann-Whitney test P value < 0.05).

Conclusion: Our finding established that apoptosis is included in periodontal tissue by host or microbial factors and support the hypothesis that apoptotic mechanism could be implicated in inflammatory process associated with gingival tissue degeneration observed in periodontitis. Indeed, apoptosis has strong effects in sever destruction in aggressive periodontitis.
