Prevalence Of Pulp Stones After Orthodontic Treatment - A Review

Abstract

The presence of various forms of calcification within the pulp is not rare but the frequency of this calcification is difficult to estimate. Pulp stones are pulpal calcification thought to arise around the central nidus of the pulp tissue, survival of which depends upon continuous blood supply. 

This review paper aims to discuss the correlation between orthodontic treatment and pulp stone formation. Various studies were conducted and it was found that a significant increase in pulp stone was present at the end of orthodontic treatment. Maxillary 1st molar has exhibited the highest frequency in the occurrence of pulp stones followed by maxillary 2nd molars and mandibular 1st molars. There is a statistically significant difference between the incidence of pulp stones in maxillary and mandibular arches during orthodontic treatment. So far no relation has been detected between pulp stones and gender and between pulp stones and right and left sides of both the arches. Based on the studies, Orthodontic treatment might lead to pulp stone formation. This is attributed to the fact that orthodontic forces might alter the blood supply and vascular pressure leading to calcifications.
