The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as pos...

INTRODUCTION The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection (PAD) system to dentin with different root canal sealers by using a push-out test design. MATERIALS AND METHODS A total of 30 extracted mandibular premolar teeth with single and straight roots were used. The crowns were removed and the root canals were prepared by using ProTaper rotar...

INTRODUCTION Inappropriate condensation of gutta-percha or improper use of sealer can lead to voids in root canal filling material and consequent failure of the treatment. Timely detection of voids within root canal filling may prevent complications. In this study, we compared the accuracy of digital and conventional radiograph for detecting voids within root canal fillings. MATERIALS AND MET...

INTRODUCTION The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in removal of gutta-percha (GP) and sealer from the root canal walls with and without use of solvent. MATERIALS AND METHODS Sixty single-canalled distal roots of mandibular molars were prepared and root filled with gutta-percha and AH26. Each canal was randomly allocated to receive one of...

OBJECTIVE The purpose of this study was to compare the depth of dentinal tubule sealer penetration in the apical thirds of severely curved root canals obturated with Resilon/Epiphany self-etch (SE) or gutta-percha/AH Plus using scanning electron microscopy. MATERIALS AND METHODS A total of 34 extracted human mandibular molars with 25-40° curvature of the mesial root canal were selected for th...

Context: Use of root canal solvents has increased the success rate endodontic retreatment and it made procedure faster simpler. Aims: During retreatment, a solvent facilitates removal obturation material sealer by softening it, so as to obtain free debris microorganisms. Hence an invitro study was done evaluate compare dissolving effect RC Solve, Eucalyptus oil G-sol on AH Plus Root Canal Seale...

INTRODUCTION The aim of the present study was to evaluate the physicochemical properties of a bioceramic root canal sealer, Endosequence BC Sealer. Radiopacity, pH, release of calcium ions (Ca(2+)), and flow were analyzed, and the results were compared with AH Plus cement. METHODS Radiopacity and flow were evaluated according to ISO 6876/2001 standards. For the radiopacity analysis, metallic ...

The results after 4 to 24 months were reported previously. Of 180 atients, 120 responded to the 5-year recall. Success of oot canal treatments w...

AIM To investigate the pattern of routine endodontic practices among Nigerian dentists. MATERIALS AND METHODS This study was a questionnaire-based survey of samples of dentists in the Nigerian cities of Enugu and Benin. The self-administered questionnaire contained 25 close-ended questions with multiple choice options. The data collected included demographic details of respondents, root canal...
