Abstract

ackground: Oral cancers are most common cancers worldwide today and its morbidity and mortality rates are still high in most countries. Typically, oral cancer is preceded by a premalignant state for a long time.  The survival rates for oral cancer patients will significantly be improved provided lesions are detected and treated at the infancy stage. The World Health Organization has clearly identified prevention and early detection as major objectives in the control of the oral cancer burden.  Early diagnosis is therefore of paramount importance. It is important to screen patients for these conditions so as to detect malignant changes early. Previously, the screening of patients for oral cancer and potentially malignant disorders (PMD) has relied mainly on conventional oral examination. Nowadays, many newer techniques are available to potentially assist in the screening of healthy patients for evidence of oral cancer. In recent years, there has been a growing and persistent demand for new non-invasive, practical diagnostic techniques that might facilitate the early detection of oral PMDs. The present paper reviews the main techniques used to improve premalignant lesion diagnosis.
