OBJECTIVE: To investigate the difference of apoptosis and expression of apoptotic related genes p53 bcl-2 C-myc in the development of oral lichen planus(OLP).

METHODS: Apoptotic cells were detected by TUNEL and immunohistochemical method was used to study P53 bcl-2 C-myc expression in 45 samples with OLP(23 cases of erosive OLP group and 22 cases of non erosive OLP group).

RESULTS: Apoptosis occurred in 100% of the cases and apoptotic index(AI) was 24.3%+/-12.0% (1.9%-50.5%). AI of erosive OLP group was 19.0%+/-10.4% (1.9%-50.5%), and AI of non erosive OLP was 29.4%+/-11.2% (10.4%-49.3%). The obvious differences existed between erosive group and non erosive group (P<0.05). The expression of p53 bcl-2 C-myc positive rates were 31.1% 35.5% 33.3% respectively. The p53 bcl-2 C-myc positive rates in erosive OLP group were 39.1% 52.2% 43.2%and that with non-erosive OLP group were 22.7% 18.2% 22.7% respectively. There was only statistically significance between erosive group and non-erosive group (P<0.05) in expression of bcl-2.

CONCLUSION: Apoptosis and apoptotic related genes p53 bcl-2 C-myc participate in clinical development of OLP. The changes of AI are related to the chronic inflammation of lesion with OLP. We should attach importance to over expression of bcl-2 in erosive OLP.
