The micronucleus assay in the oral exfoliated cells of tannery workers.

Context: Micronuclei, tannery workers, chromium, papanicolaou (PAP) stain.

Aims: The presence of micronuclei are biomarkers broadly used; the detection of micronuclei offers a great opportunity to monitor individuals or populations exposed to mutagenic, genotoxic or teratogenic events, mainly the evaluation of micronucleogenic cells presence in epithelial tissues.

Settings And Design: Tannery workers with and without tobacco usage was considered for microneuceli assessment using PAP stain, 50 patients without usage of tobacco was taken and 50 patients with usage of tobacco was considered.
