Perforation is an artificial communication between the root canal system and supporting tissues of the teeth. Root perforation complicates the treatment and deprives the prognosis if not properly managed. A wide variety of materials and techniques are available to seal the perforations. Literature shows many reviews on diagnosis, treatment plan and factors affecting the prognosis of perforation repair. Nonsurgical perforation repair should be first sort but difficulties such as extrusion and inadequate sealing of the repair material are encountered. Internal matrix concept for perforation repair provides advantage, as it helps in packing of repair material and also controls the haemorrhage from perforation site. Hydroxyapatite, collaplug, collagen are some of the materials used as matrix for perforation repair. The purpose of this case report was to describe the treatment of subcrestal perforation using absorbable collagen sponge as an internal matrix and biodentin to seal the perforation site.
