A histoenzymological study was carried out on 40 tissues specimens removed at biopsy and for surgical operations of the following lesions: 5 normal oral mucosa, 5 periapical granulomas, and 30 periapical inflammatory cysts. The purpose of this study was to study some possibly significant variations in levels o activities of oxidative enzymes, and hydrolaxes enzymes. In inflammatory cysts, enzymatic activities were similar to normal epithelium. There was high levels of acid phosphatase LDH and G6PDH activity in the central cells of apical granulomas and in the exfoliating epithelial cells of periapical inflammatory cysts. There were differency in the glycosaminoglicans activity on the different epitelial pattern.
