Abstract

The frequency of micronucleated cells (MNC) derived from exfoliated human oral mucosal cells has been measured to assess genotoxic damage in chewers of betel quid with tobacco (BQT) and tobacco with lime (T). Significantly elevated frequencies of MNC were observed in the exposed groups (BQT = 4.83 +/- 0.70; T = 5.20 +/- 0.66 per 1000 cells) compared to the control group (C = 2.59 +/- 0.37) although the levels observed were lower than those reported in the literature. No correlation was seen between age, duration and frequency of habits and the frequency of MNC in the 2 habit groups. Clastogenic agents in betel quid possibly involved in micronucleus formation are discussed.
