To evaluate the role of lactate dehydrogenase as biomarker in the progression of potentially malignant disorders in smokers and gutkha chewers.

To evaluate the role of lactate dehydrogenase (LDH) as a biomarker in the progression of potentially malignant disorders in smokers and gutkha chewers. The total of 70 individuals having the habit of chewing gutkha and smoking were selected for the study and divided into four groups. Group 1: 20 individuals having the habit of smoking, Group 2: 20 individuals having the habit of chewing gutkha, Group 3: 20 individuals having the habit of smoking and gutkha chewing, and Group 4: 10 healthy individuals. In the present study showed that unstimulated whole saliva from group 1, group 2, and group 3 individuals, there was a significant decrease in isoenzymes LDH-1 and LDH-2 and there was no effect on LDH-3 isoenzyme. In the present study, there is a significant increase in salivary isoenzyme LDH-4. The result indicated that there is an effect of carcinogen (tobacco)-enhanced activity on salivary LDH. The present study showed 70 volunteers reported a statistical significant correlation among the groups. The individuals with habit of smoking and gutkha chewing showed P value <.001 with a significant increase in the isoenzyme LDH-4. A significant increase in the buccal micronuclei of exfoliated cells in the oral mucosal cells of smokers and gutkha chewers. This shows a positive relationship between LDH isoenzymes and the individuals with the smoking and chewing of tobacco. There was a significant correlation between the levels of salivary LDH isoenzymes and cytomorphometric analysis of oral epithelium in smokers and gutkha chewers.
