Perforation in cervical 1/3rd of root or in the floor of pulp chamber has had poorer prognosis than at apical 1/3rd or middle 1/3rd of root canal.If repaired immediately, there is good prognosis.2,4,5 Various materials have been used to treat furcal perforations including zinc oxide eugenol, amalgam, cavit, super EBA, GIC, Ca (OH) , IRM, DFDB 2,3,9 and Ormocer.4,5,7 Novel materials in the field are CEM (Calcium enriched mixture) and Biodentine.32,33 The ideal material for treating radicular perforations should be nontoxic, nonabsorbable, radiopaque, and bacteriostatic or bactericidal37; it should also provide a seal against microleakage from the perforation.26,29,36
