title: The frequency and distribution of idiopathic osteosclerosis.
abstract: Full-mouth radiographs of 1921 patients were examined for the presence of radiopacities that could not be attributed to any known sources of bone formation. A total of 103 patients, or 5.4%, exhibited these foci of idiopathic osteosclerosis. Most lesions were located in the vicinity of the mandibular premolars, and the majority had some connection to the apices of the teeth. No difference in frequency between males and females was detected overall, but a statistically significant preponderance of idiopathic osteosclerosis was found in blacks, with a predilection for black females also noted.
