Human histologic evidence of periodontal regeneration following treatment of intrabony defects with enamel matrix derivative has yielded inconsistent results in recent case reports. A 46-year-old woman presenting one deep intrabony defect at the distal root of a mandibular first molar scheduled for extraction was selected for enamel matrix derivative therapy. During surgery, a notch was placed ...
objective: furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. the prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. thus, use of a biocompatible material for complete sealing of the perforation site is critically important. this ...
Background and Aim: Furcal perforation has a great impact on prognosis of endodontic treatments, requiring immediate and proper intervention. Gray MTA is applied as material of choice in repairing perforations. The aim of this study was to evaluate the repair of mechanical furcal perforations, histologically using white MTA and Portland cement and compare them with gray MTA. Materials and Metho...

introduction: iatrogenic furcal perforation is a procedural accident in endodontic treatments of primary/permanent teeth; prognosis may be favorable if a complete seal with biomaterial is immediately established. the purpose of this in vitro study was to evaluate microleakage of calcium enriched mixture (cem) cement and proroot mineral trioxide aggregate (mta) for sealing primary molar furcal p...
