The Clinical Presentation of Oral Potentially Malignant Disorders

Early detection of oral cancer improves survival rates significantly, however, the incidence of oral cancer has continued to rise in the UK - between 2002-2012, it increased by more than 30%. There is currently no national screening programme for oral cancer, so undertaking a full examination of the oral mucosa during routine dental appointments is vital. Although strong evidence is still lacking, oral cancer is thought to be preceded by oral potential malignant disorders (OPMDs) or oral precancerous diseases. These mainly present as white/red lesions within the mouth and their clinical appearance can be challenging to diagnose accurately, which can lead to them being misdiagnosed as negligible problems. Dentists must keep up to date with OPMDs detection and ensure they are capable of correctly recognising lesions that carry a potential risk. This paper aims to provide a brief overview on OPMDs, highlighting potentially malignant disorders as they may present to the practitioner, showing their typical clinical appearance, and suggesting differential diagnosis and clinical management in dental practice.
