The objectives of the study were gather information about cementomas emphasizing in its clinical, radiographical and hystological characteristics. Bibliography was taken from libraries of the Superior Medical Institute of Camagüey and "Manuel Ascunce Domenech" Provincial Hospital, and moreover, computed data bases (MEDLINE) in a review carried out from September 1995 to March 1996 were used. The study selection was performed by some independent reviewers, taking as a selection criterion those related with the topic chosen and they explained the topics, targets of this research. Within the synthesis of data it was analyzed that cementomas are lesions composed of cemento-like tissues, which are of four different types:- periapical fibrous cementum dysplasia,- benign cementoblastoma,- fibrocementoma and - multiple-familiar giant-like cementoma. They present radiographically as radiopaque images that depend on the evolution stage of the tumour. Hystogenesis is yet uncertain. Hystology is diverse. Concluding, there are four types of lesions derived from cementum -forming cells:- periapical fibrous cementum dysplasia, - benign cementoblastoma, -fibrocementoma, and -multiple-familiar giant-like cementoma. The periapical fibrous dysplasia is common in blacks, being the femenine sex the most affected one; and it frequently occurs in middle age. Incisive and premolar teeth are more affected; and mainly the jaw. Benign cementoblastoma is common in patients younger than 25 years old, generally at the jaw and it is always associated with the tooth root, causing external and internal bone expansion. Fibrocementoma, defined entity that may occur at any age and mainly in the femenine sex and white race, frequently in the jaw, causes tooth displacement. The giant-like cementoma occurs less frequently, common in middle aged- black women, it presents as radiopaque masses symmetrically distributed in the dental arches. Reabsorption and visible displacement are not present.
