Comparative Evaluation of Dentinal Microcrack Incidence After Root Canal Preparation by BioRaCe and Edge Taper Platinum
Background and Aim: Preparation of root canal with rotary nickel-titanium (NiTi) instruments may potentially create microcracks that can lead to vertical root fracture. This study aimed to compare the incidence of crack formation by BioRaCe and Edge Taper Platinum systems in the mesiobuccal canals of extracted first mandibular molars. Materials and Methods: In this experimental study, 50 first...
متن کاملThe Role of Root Canal Preparation on Apical Geometry: A Review of the Literature
The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...
متن کاملcomparison of apical leakage in leteral condensatsion with and without tug-back with Two types of root canal sealers
in order to deermine the effect of root canal cealer on microleakage of obturated root canal by lateral condensation technique(LCT) with and without tug-back(TB).seventy exteracted single root canal teeth were examined.after preparation of root canal with step-back technique,teeth were divided to six groups as follows:5 teeth as positive control group that obturated by LCT with gutta-perch itho...
متن کاملEvaluation of apical filling after root canal filling by 2 different techniques.
OBJECTIVE To determine the percent gutta-percha-filled area in the apical third of root canals after filling with 2 different root filling techniques. MATERIALS AND METHODS Thirty extracted human lower premolars were instrumented with ProTaper rotary files (Dentsply Maillefer) and then randomly divided into 2 groups of 15 teeth each. The first group was filled using the single-cone technique ...
متن کاملRe: A micro-computed tomographic evaluation of apical root canal preparation using three instrumentation techniques.
AIM To investigate the morphological changes in the apical third of the root canal after preparation with three techniques. METHODOLOGY Forty molar teeth were scanned using micro-computed tomography before and after instrumentation with: Group 1 - stainless steel K-files using the balanced force technique; Group 2 - stainless steel K-files (balanced force) and then refining the apical prepara...
متن کاملCorrelation between remaining length of root canal fillings after immediate post space preparation and coronal leakage.
The seal provided by root canal fillings after post space preparation was studied using a pressure-driven radioactive tracer assay. The coronal part of root canal fillings was immediately removed, using a hot plugger, to a remaining length of either 3, 5, 7, or 9 mm. Intact root canal fillings of 14 mm served as control. Application of air pressure of 130 mm Hg to the tracer solution drove it t...
