Tumoral calcinosis is a rare familial disorder characterized by masses of calcification in periarticular soft tissues. Few reports in the literature have described dental abnormalities in patients with tumoral calcinosis. These dental abnormalities include short bulbous roots, pulp stones, and obliteration of the pulp cavity. In this case report, we describe the dental radiographic findings in a patient with tumoral calcinosis; these findings were similar to dentin dysplasia. Periapical radiolucencies with noncarious teeth were observed in addition to the dental findings previously reported.
