Comparative evaluation of apical debris extrusion between RaCe and Komet F6 An Ex-Vivo Study
Background & Aim: Apical extrusion of debris is one of the reasons for flare-up(pain,swelling,or both). This study aimed to determine the apical debris extrusion of two rotary systems(RaCe and Komet F6 SkyTaper) in curved mesiobuccal canals of mandibular first molars. Material and methods: Thirty mandibular first molars (with mesiobuccal canal curvature 25-35 degree) were included in this ex...
متن کاملLess extrusion debris during the retreatment of curved canals using twisted files with higher rotational speeds: an ex vivo study
BACKGROUND Debris extrusion from the apical foramen can be problematic in severely curved canals. This study aimed to assess the use of Twisted Files (TF) at different rotational speeds during retreatment, compared with manual technique using Triple-Flex Files (TFF). METHODS Forty-eight mesiobuccal root canals were randomized to four groups (n = 12 per group). In groups A, B, and C, gutta-per...
متن کاملApical extrusion of debris by manual and mechanical instrumentation.
The aim of the present study was to assess the presence of apically extruded debris and evaluate the influence of canal curvature on the amount of debris produced by manual and mechanical techniques. Forty single-rooted mature teeth with 15 to 30 degree of root canal curvature were selected. The presence of only one foramen was confirmed using a magnifying lens. A size 15 K-file was placed up t...
متن کاملComparison of apically extruded debris and instrumentation time using rotary, endodontic handpiece and hand files in primary molar teeth: (In-vitro )
Abstract Background & Aim : This study was aimed to compare the instrumentation time and the amount of debris extruded apically during root canal preparation using hand files ,Mtwo rotary system and endodontic handpiece in primary molar teeth. Method & Material : In this experimental study, sixty roots of primary molars of human teeth were assigned to three groups (for each group, n=20). The...
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,...
