Prevalence of pulp stones using digital panoramic radiograph: A preliminary retrospective study

Background: Isolated calcified masses found in the pulpal space of teeth are called pulp stones (PS). Different populations demonstrate a varied prevalence of PS. Aim: The aim of this preliminary study was to evaluate the prevalence of PS in the Pondicherry population, along with its relationships with gender, age, tooth type, and location using digital panoramic radiographs. Materials and Methods: One hundred good-quality digital panoramic radiographs of healthy individuals between 18 and 70 years were selected from the records of the Department of Oral Medicine and Radiology. PS were recognized as well-defined dense radiopaque masses in the intrapulpal space. Two examiners independently analyzed the radiographs for the presence of PS. Results: Out of 100 radiographs, PS were found in 54 radiographs. Males showed a higher incidence (57.4%) than females (42.6%). Furthermore, patients between 20 and 35 years showed a greater prevalence (64.81%) and the incidence was higher in the maxillary arch (70%) than the mandibular arch (30%) with the right side being more frequent. In addition, first molars showed a greater overall prevalence. Conclusion: It was found that the prevalence of PS was 54%. Digital panoramic radiographs can be used as a preliminary investigative technique for the identification of PS.
