These changes are detected during routine ra- diographic evaluations as single or multiple circular or ovoid radiopaque images measuring more than 200 μm. Used in Endodontics, cone-beam computed tomography (CBCT) may demonstrate root and coronary anatomy and detect calcifications, which may help to make an accurate diagnosis. Objective: This study assessed the prevalence of pulp stone on CBCT scans retrieved from the collection of the Radiology Center of the School of Dentistry — São Leopoldo Mandic. Methods: A total of 181 images were analyzed by means of multiplanar reconstructions. Results were subjected to biostatis- tics. Results: The prevalence of pulp stones was 55%. Prevalence was highest in the 31-40 year age group (89.7%) and in the group of teeth that had been restored (61%). Teeth #16 was the most affected, at a preva- lence of 12.8 %, followed by #17 (10.3%). Conclusion: The prevalence of patients with pulp stones was 55%. Pulp stones were not associated with aging. Most teeth with pulp stones were maxillary permanent molars, and tooth restoration may be the cause of stone formation. Keywords: Dental pulp diseases. Dental pulp calcification.
