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...

The purpose of this study was to evaluate the microleakage of various root-end filling materials using a fluid filtration system. Sixty extracted human single-rooted teeth were used. The crowns were removed, the canals prepared, and root-end fillings placed. The samples were divided into two control and five experimental groups. The root-end filling materials tested were: amalgam, Intermediate ...

OBJECTIVES The aim of the present study was to determine radiographically the different reasons and problems of endodontic treatment failure. METHODS The periapical radiographs of 100 patients with one hundred teeth (130 root canals) were examined to identify the problems and failures of endodontic treatment. The various reasons of failure that is under filling, poor filling, over filling and...

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...

One-visit mineral trioxide aggregate (MTA) apexification is gaining in popularity over the use of calcium hydroxide barriers. This study examined the sealing properties of two MTA apexification procedures using an in vitro apexification model. White MTA was introduced into instrumented single-rooted canals with standardized artificially created open apices to form 3- to 5-mm-thick orthograde ap...

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...

OBJECTIVES The aim of this study was to assess the prevalence of periapical lesions in root canal-treated teeth in a Turkish Cypriote population and to investigate the influence of the quality of root canal fillings and coronal restorations on the prevalence of periapical lesions. SUBJECTS AND METHODS The sample for this cross-sectional study consisted of 1,006 adult patients seeking routine ...

background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...

IRM has been recommended for root end filling during endodontic surgery. This study evaluated the seal of IRM root end fillings prepared with various powder to liquid ratios (P:L) at extended time intervals using a fluid filtration method. The P:L of IRM evaluated included 2, 3, 4, 5, and 6 g/ml and the P:L which resulted from the manufacturer's recommended scoop and dropper. Ten teeth were eva...

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....
