AIM To re-examine a population after 20 years and evaluate changes in prevalence of endodontic treatment and apical periodontitis, as well as the technical quality of root fillings. METHODOLOGY One hundred and fifteen out of an original 200 patients living in the northern part of Sweden were re-examined with a full mouth radiographic survey after 20 years. Frequencies of root canal treated te...

The aim of this study was to evaluate the standard quality of 1,347 root fillings performed by postgraduate students in Endodontics according to 3 radiographic quality parameters. The analyzed quality parameters included apical extension (AE), taper (TA) and homogeneity (HO), which received scores S2 (ideal standard), S1 (slight deviation) or S0 (accentuated deviation). A perfect filling (PF) r...

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...

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...

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...

Introduction: There is substantial evidence that the technical quality of root canalfilling has a significant effect on the outcome of root canal treatment. Theaim of this study was to evaluate the technical quality of root canal fillingsperformed by dental students. Methods: The records of 325 teethradiographs, treated by dental students in 2008-2009 in Babol Dental School,were selected and ev...

BACKGROUND/OBJECTIVE Progress in endodontic techniques and methodological advances have altered root canal therapy over the last decades. These techniques and methods need periodical documentation. This observational study determined the current prevalence of endodontic treatments, and investigated the relationship of various factors with the periapical status in a Lower Austrian subpopulation....

OBJECTIVES The purpose of this study was to evaluate the radiographic quality of root canal fillings performed by first and second clinical year dental students at the Faculty of Dentistry in Süleyman Demirel University, Turkey. METHODS The technical quality of 833 root canal fillings was evaluated by three examiners according to the density of the filling and the distance between the end of ...

Background: The education of undergraduate dental students in endodontics should be of high standards to enable newly graduate dentists to deal with the most commonly encountered endodontic clinical problems. Hence, the objective of this study is to evaluate radiographically the quality of root canal fillings done by undergraduate students in the College of Dentistry, King Khalid University, Sa...

OBJECTIVE This study was performed to determine in vitro the short- and long-term sealing ability of a recently developed silicon-based root canal filling material (Gutta-Flow). STUDY DESIGN Sixty human upper central incisors were divided into 3 groups (n = 20). The root canals were instrumented and obturated with laterally compacted gutta-percha and AH26 sealer (group 1), continuous-wave the...
