Abstract Aim To evaluate the efficacy of filling material removal from oval‐shaped canals after use supplementary files (XP‐endo Finisher and XP‐endo R) through microcomputed tomographic (micro‐CT) analysis. Methodology The root twenty maxillary single‐rooted teeth were prepared with Reciproc R25 filled gutta‐percha AH Plus sealer using continuous wave condensation technique. then retreated R40 instruments. After this, specimens assigned to two groups according cleaning approach, R. surface...
To compare the shaping ability of four root canal instrumentation systems in oval-shaped canals using micro-computed tomographic analysis.Forty anatomically matched mandibular incisors were scanned and assigned to groups (n = 10), according preparation protocol: BioRace, Reciproc, Self-Adjusting File (SAF) TRUShape systems. After instrumentation, specimens rescanned, registered pre- postoperative datasets examined evaluate percentages accumulated hard-tissue debris, untouched walls dentine...
The aim of this study was to compare the percentage non-instrumented area root canals prepared with different enlargements using single-file reciprocating systems (Reciproc and WaveOne) a conventional multi-file rotary (BioRaCe) system by micro-computed tomographic analysis. Thirty mesial roots mandibular molars moderate curvature (10° 20°) presenting type II Vertucci canal configuration similar internal volume were chosen scanned at an isotropic resolution 14.16 µm. sample assigned 3 groups...
Abstract Aim To assess the frequency in which Reciproc instrument reaches full working length ( FWL ) of mandibular molar canals without a glide path. Methodology From pool molars, 253 root were classified as straight (G1) and, 249 moderately curved (G2) following Schneider's method. A R25 VDW , Munich, Germany) was advanced any previous All cases where instruments reached ‘Reaching ’ RFWL ). When not by R25, ‘Not Reaching NRFWL Pearson's χ 2 test compared (i) distributions and for each...
To evaluate the amount of apically extruded debris produced by ProTaper Universal (PTU), Next (PTN), WaveOne (WO) and Reciproc (R) systems after large apical preparations.Sixty mandibular premolars with a single canal were selected randomly assigned into 4 groups (n = 15) according to system used for root preparation: PTU, PTN, WO R groups. Canal preparations performed up size 40 in each group. Distilled water was as an irrigant, from tooth collected pre-weighted glass vials dried. The...
The dentinal radicular microcrack is a difficult clinical problem to diagnose and treat, it one of the most common reasons for tooth extraction. These microcracks start in dentin, laboratory studies have linked crack formation some routine endodontic procedures, namely root canal preparation, obturation, retreatment. Most these were performed using destructive methods, such as sectioning technique, previously developed study internal anatomy teeth. Nowadays, technological advances field...
To evaluate the performance of XP-endo Finisher R instruments when removing root filling remnants from oval-shaped canals using microcomputed tomographic (micro-CT) imaging as analytical tool. Passive ultrasonic irrigation (PUI) was used a reference technique for comparison.Twenty mandibular incisors with were matched based on similar anatomic features canal (volume, aspect ratio and 3D configuration) after scanning procedures. The prepared Reciproc R25 instruments, filled gutta-percha AH...
To evaluate, using an experimental immature tooth model, the fracture resistance of bovine incisors submitted to different reinforcement treatments with mineral trioxide aggregate (MTA).An model was created by sectioning coronal and apical portions 40 8 mm above 12 below cementoenamel junction. The root canals were irrigated 1.0% sodium hypochlorite. They enlarged both coronally apically number 703 carbide burs (ISO: 500-104-168-007-021) their internal diameter standardized 2.1 mm. specimens...
To determine the correlation between leakage and sealer penetration into dentinal tubule.The root canal of 60 mandibular central incisor teeth were prepared filled under standardized conditions. Teeth placed a device to assess glucose using 15 psi pressure application. After 1 h, concentrations in lower chamber measured an enzymatic reaction. Each specimen was then sectioned horizontally at 3, 6 8 mm from apex, standard metallographic preparation performed. The coronally facing surface each...
Abstract Aim To evaluate the effect of 17% ethylenediaminetetraacetic acid ( EDTA ), 2.25% peracetic PA ) or 10% citric CA on push‐out bond strength calcium silicate‐based endodontic sealers [ MTA Fillapex (Angelus, Londrina, Brazil) and Total Fill BC Sealer FKG , La Chaux‐de‐Fonds, Switzerland)] to root dentine after different periods immersion in phosphate‐buffered saline PBS ). AH Plus (Dentsply DeTrey, Konstaz, Germany) was used as a reference material for comparison. Methodology Thirty...
Abstract Aim To investigate the smallest dentine thickness in mesial canals of mandibular molars along cervical and middle thirds root by means a micro‐computed tomographic (micro‐ CT ) technology digital image analysis. Methodology Fifty roots having two independent (mesiobuccal mesiolingual), coronal levels, were selected scanned micro‐CT device. After reconstruction procedures, approximately 468 slices per covering 7 mm below furcation area analysed to measure (danger zone [ DZ ]) each...
Abstract Aim To introduce a new method to select anatomically matched teeth using micro‐computed tomographic (micro‐CT) technology. Methodology Single‐rooted mandibular incisors with single root canal ( n = 60) were selected and distributed into three experimental groups according the used for matching 10 pairs of in each group. In group 1, randomly from pool teeth. 2, paired based on measurement width 5 mm apex radiographs taken buccolingual mesiodistal directions. 3, scanned (pixel size...
