RESULTS
An experimental animal study was conducted to study the histological
effects of green tea extract on prevention of nicotine-induced changes
on buccal mucosa of albino Wistar rats. Left buccal mucosa was
selected to inject nicotine to group B and C. The animals of group C
were also given green tea extract once daily orally. Group D animals
were only given green tea extract orally.
The group A with normal oral mucosa was used as control.
Histologically normal buccal mucosa of an adult rat is composed of an
epithelial outer layer and underlying lamina propria. The epithelium of
buccal mucosa of albino rat is stratified squamous keratinized, consist-
