A clinicopathological study of the pre-malignant conditions of oral cavity.

The pre-malignant conditions of the oral cavity are those which has got a potentiality to turn malignant in its due course if left untreated. It was only in 1967 when an international reference center for the study of Oral Pre-cancerous Lesion was established by the World Health Organization. The main importance was given to Leukoplakia. The conditions considered as premalignant are Leukoplakia, Lichen planus, Oral submucous fibrosis and erythroplakia. There lesions has got a very close association with the local habits practised by the people. So in this paper this point has been highlighted.The study has included the patient within a time span of one year from 5th April, '94 to 4th April '95. Though the number of the patients is not much but we find it sufficient enough to bring awareness on these potentially dangerous lesion thereby preventing oral cancers.
