In this paper we have realized a study on 43 patients on which the retro-alveolar radiological exam has shown the existence of a calcareous structure within the pulp chamber having in view a better knowledge of this structure and its etiology, way of forming and pathological implications. For 16 of the patients the radiological exam was supplemented by a microscopic examination. Radiologically, the denticles were noticed more often in the pulp chamber of the molars. The examination of the histological samples has evidenced aspects such as the size, shape and structure of the denticles. The concentric disposition of the tissue elements shows that in the formation of a denticle there is a "center" around which a conjunctive substance avid of calcium salts is deposited. The microscopic aspects noticed on large denticles allowed us to sustain the hypothesis that in a large pulp chamber many denticles form simultaneously and grow up and merge generating a large-sized unique calcareous structure.
