The failures of root canal preparation with hand ProTaper
UNLABELLED The failures of root canal preparation are due to some anatomical deviation (canal in "C" or "S") and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. OBJECTIVES Our study was made on technique errors while preparing the canal roots with hand ProTaper. METHODO...
متن کاملComparative study of six rotary nickel-titanium systems and hand instrumentation for root canal preparation.
AIM To compare ex vivo various parameters of root canal preparation using a manual technique and six different rotary nickel-titanium (Ni-Ti) instruments (FlexMaster, System GT, HERO 642, K3, ProTaper, and RaCe). METHODOLOGY A total of 147 extracted mandibular molars were divided into seven groups (n = 21) with equal mean mesio-buccal root canal curvatures (up to 70 degrees), and embedded in ...
متن کاملComparison of apical debris extrusion during root canal preparation using instrumentation techniques with two operating principles: An in vitro study
AIMS The aim of this study was to quantify the debris extruded apically from teeth using rotary and reciprocation instrumentation systems. SUBJECTS AND METHODS Eighty extracted human mandibular premolars with single canals and similar lengths were instrumented using ProTaper Universal (40, 06; Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Next (40, 06; Dentsply Maillefer, Ballaigues,...
متن کاملEfficacy of automated versus hand instrumentation during root canal retreatment: an ex vivo study.
AIM To compare automated and manual instrumentation techniques for removing filling material from root canal walls during root canal retreatment. METHODOLOGY One hundred extracted human single-rooted teeth were root filled and stored. Specimens were divided into two groups: group A, Endofill plus gutta-percha; group B, Sealer 26 plus gutta-percha. The filling material was removed using the fo...
