We use the term epithelial dysplasia (ED) when we’re in the presence of a variable combination of phenomena that indicate loss in maturation and an incorrect cellular proliferation. Nowadays oral ED is the best diagnostic approach in the assessment of the malignant capacity of premalignant lesions. Nevertheless, its quantification is a subjective process; with none patognomonic or unquestionable parameters are set. There ´s some controversy in its quantification and qualification. We still don’t have the definitive markers than can predict its existence, but more important its evolution in premalignant oral lesions. In this paper we review the most important aspects in the evaluation of oral ED, and contribute with our considerations.
