Pulp calcifications in primary teeth.

Abstract

One hundred and twenty primary maxillary and mandibular extracted teeth were collected to study the occurrence and nature of pulp calcifications. The teeth were serially sectioned, stained with hematoxylin and eosin, examined by light microscope. Pulp calcifications were observed in 31 (25.8%) teeth. Two types of pulp calcifications were noticed i.e., diffuse calcifications and free/attached type denticles. The occurrence of pulp calcification appears identical in all teeth except in the first primary molar which is statistically not significant (P greater than 0.05). The low prevalence of pulp calcifications in the primary teeth support the view that pulp calcification increases as the age advances.
