Abstract

The main objective in paediatric dentistry is to maintain primary teeth in the oral cavity till exfoliation. Endodontic therapy has to be done to treat infected pulp. Various obturating materials are zinc oxide eugenol (ZOE), iodoform,
Vitapex, metapex, calcium hydroxide, Endofl as, etc. were used in primary teeth but none of these materials have the ideal obturating properties. In primary teeth, a tight apical seal, complete debridement of the canals and
obliteration of the canal space is not always possible, even in pulpectomies that succeed. Because of open apices due to resorption there is no apical barrier that can prevent the extrusion of the fi lling material.
