internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha ...

persistent microorganisms in the root canal are known to cause endodontic treatments failure. overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions. retrieval of overextended gutta-percha with a nonsurgical approach can prove to be a challenge. this case describes the nonsurgical management of a large periapical lesion associated with ove...

objective: application of chemical solvents especially in problematic canals is usually a part of the retreatment process.this study was performed to compare the solubility of gutta- percha and resilon in chloroform and to find the effect of sample thickness as well as the time of shaking on their solubility. materials and methods: specific weight of resilon and gutta-percha was placed in a sam...

A customized acrylic-resin template with gutta percha markers was fabricated for a human cadaver mandible. Twelve measurements were made between gutta percha markers and between the markers and known mandibular anatomic locations. Periapical, panoramic, and computerized tomographic radiographs were taken of the mandible and stent. Similar readings were recorded from the radiographs. The average...

The use of gutta-percha as a standard obturation material over more than 100 years has made little changes in the obturation technique. With the advent of bonding and composite resins as a routine restorative material, the concept of bonded obturation has come into picture. The Resilon-Epiphany system has brought about a paradigm shift in the conventional obturation technique. This article expl...

Three clinical cases involving teeth with open apices and apical periodontitis were treated using different protocols. The first case was managed with intracanal calcium hydroxide paste for 12 months before obturation with gutta-percha and sealer. In the second case, an apical plug of mineral trioxide aggregate (MTA) was used before obturation with gutta-percha and sealer and treatment was comp...
