Retreatment Efficacy of Continuous Rotation Versus Reciprocation Kinematic Movements in Removing Gutta-Percha with Calcium Silicate-Based Sealer: SEM Study
Author(s): Raghad Noori Nawaf* and Raghad Abdulrazzaq Alhashimi
Background: The removal of maximum amount of root canal filling materials is necessary for successful endodontic retreatment, several rotary systems have been used for removing obturating materials. The aim of this study: To evaluate the effectiveness of continuous rotation retreatment systems (ProTaper Universal retreatment and XP-endo Retreatment) versus reciprocating systems (Reciproc Blue and Wave One Gold) in removing gutta-percha point and calcium silicate-based sealer from the root canal during endodontic retreatment. Materials and Methods: Forty mandibular second premolars with straight oval canal were used and instrumented with ProTaper Next system up to size X3 file, then obturated with gutta-percha and TotalFill BC Sealer using single cone technique. The samples were divided into four groups according to the retreatment system use.. Read More»
