A descriptive, retrospective, cross-sectional, and analytical study of 35 patients with homogeneous oral leucoplakia associated to the smoking habit, assisted at the Outpatient Department of Maxillofacial Surgery from "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out from January, 2007 to the same month of 2009, aimed at determining the presence not only of changes of keratinisation as parakeratosis, orthokeratosis, and dyskeratosis, but also of epithelial dysplasia. The primary information was obtained through the histological-pathological study of the biopsies processed in the Pathology Department of the aforementioned institution. The distinctive microscopic characteristic was the hyperparakeratosis, with the presence of the abnormal development of the tissue or without it.
