Evaluation of bond strength of various epoxy resin based sealers in oval shaped root canals
BACKGROUND The aim of this study was to evaluate the bond strength of AH plus, Acroseal, and Adseal to the root canal dentin. METHODS A total of 36 single-rooted, mandibular premolar teeth were used. Root canal shaping procedures were performed with ProTaper rotary instruments (Dentsply Maillefer) up to size F4. The prepared samples were then randomly assembled into 3 groups (n = 12). For eac...
متن کاملFibre post adaptation and bond strength in oval canals.
AIM To evaluate ex vivo the bond strength and adaptation of fibre posts with oval and circular cross sections luted in oval canals with post spaces prepared using dedicated drills or ultrasonic tips. METHODOLOGY Forty extracted premolars with oval canals were root filled, then randomly divided into four groups according to the post space preparation device and the shape of the luted fibre pos...
متن کاملComparison of Bacterial Leakage between 3 Different Root Canal Obturation Techniques in Oval Shaped Canals
Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 gr...
متن کاملEfficacy of three thermoplastic obturation techniques in filling oval-shaped root canals.
The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n H...
متن کاملEx vivo evaluation of three instrumentation techniques on E. faecalis biofilm within oval shaped root canals.
The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided...
