It is referred to plainly as ‘oral leukoplakia’ (OL) before 20041. Thereafter, it is called PVL. The WHO classified it among the “potentially malignant disorders”2.

The main other function of the periodontium apart from supporting the teeth is to protect and provide nourishment to the teeth. The tissues ...
