Abstract

Pulpectomy is one of the treatment options used to maintain primary teeth with radicular pulpal tissue inflammation or that have become nonvital, until normal exfoliation. The primary goal of this procedure is to maintain arch length and function by preserving primary teeth that are essential to proper guidance of the permanent dentition. Other objectives of preserving primary teeth are to enhance esthetics and mastication, prevent aberrant tongue habits, aid in speech, and prevent the psychological effects associated with tooth loss. The treatment consists of removing the pulp tissue associated with micro-organisms and debris from the canal and obturating with resorbable filling material. Familiarity with the complexity of primary tooth canal systems, their formation and resorption pattern dictates the parameters that affect the probability of success of root canal therapy. Moreover, the obturating material as well as obturation technique used that is capable of densely filling the entire root canal system and providing a fluid tight seal from the apical segment of the canal to the cavosurface margin in order to prevent reinfection also significantly influences the success rate of the endodontic therapy. Several methods have been used to deliver obturating materials into the root canals. The purpose of this article is to throw light on various obturation techniques used in deciduous teeth with their comparison, pros and cons.
