Abstract

Oral potentially malignant disorder (OPMD) is defined as an altered epithelium with an increased likelihood for progression to squamous cell carcinoma by the World Health Organization. In most patients with oral cancer, malignancy is preceded by an existing OPMD. Leukoplakia, erythroplakia and oral submucous fibrosis are considered to be the most common types of OPMDs, while special emphasis has been placed on the premalignant nature of oral lichen planus. Prevalence of OPMD has been reported as 6.7% among estate workers in Sri Lanka and population prevalence for leukoplakia was 46.1 per 1000 and 16.4 per 1000 for oral submucous fibrosis. In this chapter diverse clinical presentations and histopathology of OPMD are discussed with more than 60 illustrations.
