Abstract

Introduction: Pulp stones are foci of calcification in the dental pulp. During the orthodontic tooth movement, a complex series of tissue reaction occurs. Studies show that the orthodontic force application may cause pulpal changes like pulpal calcifications. Hence; we assessed the prevalence of prevalence of dental pulp stones in patients undergoing orthodontic treatment. Materials and Method: A total of 50 patients who were scheduled to undergo non-extraction orthodontic treatment were included. Pre-treatment and Post-treatment radiographs were taken in all the patients. Evaluation of the permanent molars (maxillary and mandibular) was done, both pre-treatment and post-treatment. Interpretation of the radiographs was done by skilled and experienced oral radiologists. Diagnosis of pulp stones was done when definite radiopaque bodies as dental pulp stones were noted as present or absent. All the results were recorded in Microsoft excel sheet. Results: At pre-treatment time, prevalence of pulp stones was found to be 26 percent, while at post-treatment time, the overall prevalence of pulp stones was found to be 48 percent. Significant results were obtained while comparing the pretreatment and post-treatment prevalence of pulp stones. Conclusion: Formation of pulp stones might be triggered under the effect of orthodontic trea

Pulp stones are foci of calcification in the dental pulp
Formation of pulp stones might be triggered under the effect of orthodontic treatment
Pulp stones are radiologically variable; they may occur as a single dense mass or as several small radiopacities seen within pulp chambers or root canals, or may extend from the pulp chamber into root canals

Summary

Introduction

Pulp stones are foci of calcification in the dental pulp. During the orthodontic tooth movement, a complex series of tissue reaction occurs. Pulp stones are foci of calcification in the dental pulp Their cause is unknown, and no firm evidence exists that they are associated with any systemic or pulpal disturbance.[1] Pulp stones are radiologically variable; they may occur as a single dense mass or as several small radiopacities seen within pulp chambers or root canals, or may extend from the pulp chamber into root canals. They occur in all tooth types but occur most commonly in molars. Studies show that the orthodontic force application may cause pulpal changes like alteration in pulpal respiration rate, pulpal obliteration by secondary dentin formation, internal root resorption, cyst formation, pulpal necrosis and pulpal calcifications.[4,5,6]
