Comparison 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 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...
متن کاملSuboptimal debridement quality produced by the single-file F2 ProTaper technique in oval-shaped canals.
INTRODUCTION The aim of this study was to determine whether the debridement quality of the single-file F2 ProTaper instrumentation technique is comparable to a full conventional ProTaper sequence in both round and oval-shaped root canals. METHODS Fifty-four recently extracted vital lower incisors were instrumented with either a full range of ProTaper Universal instruments in rotary motion (gr...

متن کاملOval-shaped canal retreatment with self-adjusting file: a micro-CT study
Aims The primary goals of endodontic treatment are to debride and disinfect the root canal space to the greatest possible extent, and to seal the canals as effectively as possible, aiming to establish or maintain healthy periapical tissues. Although initial root canal therapy has been shown to be a predictable procedure with a high degree of success, failure can occur after treatment. Lack of h...
