    Evaluation of Apically Extruded Debris Using Continuous Rotation, Reciprocation, or Adaptive Motion
    (Associacao Brasileira de Divulgacao Cientifica, 2018) Sen, O.G.; Bilgin, B.; Koçak, S.; Sağlam, B.C.; Koçak, M.M.
    The aim of this study was to compare the amount of apically extruded debris during root canal instrumentation using ProTaper Next (PTN), Twisted File (TF) Adaptive, and Reciproc instruments. Forty-five extracted human maxillary canines were selected and randomly assigned into 3 groups. The root canals were prepared using PTN instruments with continuous rotation (n=15), TF Adaptive instruments with adaptive motion (n=15), Reciproc instruments with reciprocating motion (n=15). During the preparations, canals were irrigated using distilled water and material extruded apically was collected in pre-weighed Eppendorf tubes. After a 5-day drying period in an incubator, the tubes were weighed and the dry weight of the extruded debris was calculated. Data distributions were assessed via the Shapiro-Wilk test, and groups were compared via the Kruskal-Wallis test. The greatest amount of debris extruded by TF Adaptive and the least by PTN, but the difference was insignificant between groups (p=0.259). All instrumentation systems were associated with debris extrusion. © 2018, Associacao Brasileira de Divulgacao Cientifica. All rights reserved.
