Abstract :

Objectives The aim of this study was to evaluate the efficacy of sonic and ultrasonic activation of epoxy-amine resin-based root canal sealer on penetration of the sealer into lateral canals compared to non-activated filling. Materials and method Thirty-six single-rooted human anterior teeth were decoronated and prepared, using the ProTaper rotary system (Dentsply Maillefer, Ballaigues, Switzerland) to F4. After the completion of the cle� procedures, lateral canals were created at 3 mm from the working length. The specimens were randomly divided into a control group (manual agitation) and two experimental groups that received a sealer application with either sonic or ultrasonic activation. The root canals were filled using cold lateral compaction and imageswere obtained from each lateral canals at 40× magnification using a stereomicroscope. The sealer penetration was evaluated using a four-grade scoring system. The data were evaluated statistically using the Mann–Whitney U tests with a 95 % confidence level (P = 0.05). Results The ultrasonic activation resulted in a better sealer penetration compared with the non-activated and sonically activated groups (P < 0.001). Sonic activation also resulted in better sealer penetration compared to the non-activated group (P < 0.001). Conclusions The use of the ultrasonic activation of an epoxyamine resin-based sealer promoted greater sealer penetration into the lateral canals. Sonic activation was not effective as ultrasonic.
