The purpose of this study was to evaluate the histopathological effect of eugenol and bis-eugenol on oral mucous membranes at the tissue organ level. Oral mucous membranes of mice were applied with three reagents, eugenol, bis-eugenol, and acetone (as the control). The control group showed a normal architecture. The eugenol group showed severe hyperkeratosis, parakeratosis, cellular edema, patchy chronic inflammation, pleomorphism and hyperchromatism of basal layer cells, indicating high mitotic activity. Comparatively, the bis-eugenol group showed mild hyperkeratosis, parakeratosis, however, the shape or arrangement of basal layer cells were normal. Bis-eugenol was considerably less toxic than eugenol.
