ABSTRACT Calcifications are common in the dental pulp, with a tendency to increase with age and irritation. Deposition of hard tissue in pulp canal space increases dentinal thickness and cause yellowish discoloration of tooth. Almost all pulp canal obliterated cases remain asymptomatic and often there is dilemma on treating such cases. Most of the clinicians face serious difficulties causing iatrogenic errors like perforation, root fracture, gouging and instrument fracture in treating such cases. The use of CBCT, magnification, DG 16 explorer and ultrasonic tips help in the location of orifices. Pulp sensibility test may give a false negative response. A thorough knowledge on root canal anatomy and variations along with operators experience play an important role in endodontic treatment of pulp canal obliteration.
