Evaluation of Gutta-Percha and Resilon Retreatment - An in-vitro study
Journal Title: Indian Journal of Dental Advancements - Year 2009, Vol 1, Issue 1
Abstract
Persistent or secondary intraradicular infection is a major cause of endodontic failures. Nonsurgical retreatment is the treatment of choice for the management of endodontic failures when access to the root canals is feasible. Endodontic retreatment consists of cleaning, shaping, and three-dimensional obturation of previously obturated root canals. Various techniques are employed to remove the root canal filling materials including the use of hand or rotary instruments with or without heat application, solvents, and/or ultrasound Ni-Ti rotary instruments have also been used for removing filling materials from root canal walls. Gutta-percha, in combination with a variety of sealers, is the most commonly used material for root canal obturation. Resilon, a thermoplastic, synthetic, polyester polymer-based root canal filling material, was recently proposed as an alternative to gutta-percha. The purpose of this study was to compare the amount of residual filling material on the canal walls in root canals filled with gutta-percha or Resilon and retreated using the Protaper treatment files.
