INTRODUCTION The aim of this study was to evaluate the effects of training duration and case difficulty on the radiographic quality of root canal fillings performed by dental students in Saudi Arabia. METHODS AND MATERIALS A longitudinal cohort study was conducted at King Saud University. Root canal treatments performed by 55 dental students from 2012-2014 were included in the study. Each stu...

background and aims. different materials have been used for root-end filling during surgical endodontic treatment. the aim of this in vitro study was to evaluate the dye penetration in different thicknesses of calcium enriched mixture (cem) cement as root-end filling material. materials and methods. following root canal filling in 70 extracted human single-rooted premolar teeth, the apical 3 mm...

AIM To determine the prevalence of apical periodontitis and assess the quality of endodontic fillings in the population of the city of Zagreb, Croatia. METHODS A total of 1462 orthopantomograms from new patients at 6 different dental practices was analyzed during 2006 and 2007. The presence of periapical lesions was determined by using the periapical index score (PAI). The quality of endodont...

Coronal restorations and posts can positively influence the long-term prognosis of teeth following root canal therapy. Final sealing the canal by placing an appropriate post and core will minimize leakage of oral fluids and bacteria into the periradicular area and is recommended as soon as possible after completion of root canal filling. Glass ionomer or MTA placed over the residual root canal ...

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 & metho...

INTRODUCTION Adequate root canal seal following retreatment is essential for a successful outcome. Resilon/Epiphany (R/E) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. This in vitro study compared the amount of apical microleakage of R/E with gutta-percha/AH26 (GP/AH26) sealer as secondary root canal filling following retreatment in human tee...

INTRODUCTION The purpose of this study was to evaluate the radiographic quality of root canal fillings by fourth-, fifth-, and sixth-year undergraduate students at Tabriz Faculty of Dentistry between 2006 and 2012. METHODS AND MATERIALS A total of 1183 root canal fillings in 620 teeth were evaluated by two investigators (and in case of disagreement by a third investigator) regarding the prese...

Meticulous cleaning, shaping and filling of the root canal system are requisites for a successful root canal treatment.. Unfortunately, canal preparation is adversely influenced by the highly complex, intricate and variable root-canal anatomy. Thorough knowledge of root canal morphology and unusual anatomy of the tooth is crucial for the practitioner. Over the years, there have been numerous st...
