Shaping Ability of XP-Endo Shaper Files With Extended Use Time and R40 Blue in Oval Canals: A Microcomputed Tomography Study in Contralateral Premolars.
J Endod
January 2025
Introduction: This study evaluated the shaping ability of the single-file XP-endo Shaper (XP-S) system, employing an extended working time, and the Reciproc Blue number 40/.06 (REC) instrument during the preparation of oval-shaped canals.
Methods: Eleven pairs of contralateral premolars with a single canal were divided into two groups (n = 11) according to the canal preparation protocol: XP-S (with an additional 45 seconds of instrumentation) and REC.
Article Synopsis
- The study aimed to create a protocol for acid-etching two types of dental cements, Biodentine and Cimmo DTA, by examining their compressive strength, bond strength, and surface characteristics after various etching times.
- Four groups of test specimens (n=12) for each cement were tested at different acid-etching intervals of 0, 5, 10, and 15 seconds.
- Results showed Biodentine had significantly greater compressive strength than Cimmo DTA, and the optimal etching methods differed: selective etching for Biodentine and a full 15-second etch for Cimmo DTA.
Apical periodontitis in endodontically-treated teeth: association between missed canals and quality of endodontic treatment in a Colombian sub-population. A cross-sectional study.
Acta Odontol Latinoam
April 2024
Unlabelled: A high prevalence of post-treatment apical periodontitis associated to variables such as endodontic treatment quality and missed canals has been reported.
Aim: The aim of this study was to evalúate the quality of endodontic treatment and the frequency of missed canals associated with teeth with apicalperiodontitis (AP) through CBCTin a Colombian sub-population.
Material And Method: This was a cross-sectional study assessing 318 cone beam computed tomography (CBCT) scans of endodontically treated teeth from Colombian individuals.
Unlabelled: The remaining filling material after retreatment can harbor bacteria and organic tissues that can influence the outcome of the therapy.
Aim: The aim of this study was to evalúate, by micro-CT, the amount of filling material remaining in the root canal after its removal using WaveOne Gold or ProDesign RT.
Material And Method: Forty human mandibular canines were instrumented with the ProTaper Next system up to the X2 instrument (25.
Unlabelled: Knowledge of root canal internal anatomy and its variations is important forproper endodontic treatment. It is therefore necessary to investigate morphological aspects among different dental groups in the same patient to define the best protocol for the case.
Aim: To evaluate the morphology and symmetry of homologous incisors, premolars and mandibular molars using cone beam computed tomography (CBCT).
