NUNES DA ROSA, L. A histopathology study of resorption cementum-dentin in the apical region of human teeth extracted chronic apical lesions. Av Odontoestomatol [online]. 2003, vol.19, n.2, pp.63-73. ISSN 2340-3152.

Twenty-one human teeth extracted with chronic apicallesions were analyzed histopathologically to determine the presence of resorptions of dentin and cementum in the apical region of these teeth. An endodontic file was introduced in each tooth for identification of the apical foramen and a roentgenography was taken with standard technique in number 2 xRay film. After decalcification the teeth were sectioned and only the apical third was analyzed. The teeth underwent the routine histological technic and histopathologically evaluated, the diagnosis of the chronic apicallesion and the presence or not of dentine and cementum resorption and compensation were observed. Nine of the chronic lesions observed were apical cysts, five granulomas and seven chronic abscesses. Out of twenty-one teeth analyzed, twenty teeth presented cementum resorption and seventeen presented dentine and cementum resorption.
