A Laboratory Investigation of the Effectiveness of Different Acids in Removing Mineral Trioxide Aggregate From Simulated Root Canals

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim was to compare the effectiveness of acids in removing MTA from root canals. Fifty acrylic blocks were filled with MTA and divided into groups – 10% hydrochloric acid; 10% citric acid; 2% acetic acid; 2% carbonic acid and 20% tartaric acid. MTA was removed with the acids, plus ultrasonic tips and rotary files.

Determination of Surface Characteristics, Solubility and Ion Release of a Calcium Silicate Root Canal Sealer

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study investigated the solubility of AH Plus Bioceramic sealer (AHPB), the ion release, and the modification of surface characteristics compared to AH Plus (AHP). Solubility was examined according to ISO guidelines in deionised water and phosphate buffer saline (PBS) for 3 months.

Impact of Instrumentation Technique on Endodontic Treatment Quality in Curved Molars: A Retrospective Analysis

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This cross‐sectional study evaluated technical failures in root canal treatments (RCTs) of curved molars (> 10°) performed by undergraduate students and their association with instrumentation techniques. Evaluations included filling extension, density, taper and ledge/zip formation.

Correlation Between LPS and LTA Levels With Clinical Features in Secondary Endodontic Infections

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study aimed to quantify LPS and LTA levels in root canals requiring endodontic retreatment due to secondary or persistent infection and evaluate the relationship between Gram‐positive and Gram‐negative virulence factors and clinical symptoms and signs.

A comparison of image artifacts with gutta-percha and different sealers on root filled teeth using cone beam computed tomography: An in vitro study

open access: yesCaspian journal of dental research, 2020
Introduction: Different materials cause artifacts in cone-beam computed tomography (CBCT) images, which, in turn, reduce the quality of images. The aim of this study was to investigate the abundance of artifacts induced by different root canal therapy ...

Ideal Horizontal X‐Ray Beam Angulation for Maxillary Molars. A Retrospective Clinical Study Using Cone‐Beam Computed Tomography

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to analyse cone‐beam computed tomography (CBCT) images to determine the ideal horizontal X‐ray beam angulations for maxillary first and second molars. CBCT scans from 85 patients were retrospectively analysed to measure the angles at which buccal root canals (MB, DB) of maxillary first (n = 170) and second (n = 157 ...
