Within the limitations of this study, our results indicate that microtomography, with proposed semi-automatic algorithm, is a useful tools for three-dimensional quantitative evaluation of dental root canal fillings. In canals filled with thermoplastic gutta-percha and Tubli-Seal, voids at the interface between the filling and canal dentine deserve special attention due to of their periapical lo...

Objectives: The aim of the present study was to evaluate the quality of root canal treatments and coronal restorations investigating their influence on the periapical status of endodontically-treated teeth in a Turkish population based on radiographic examination. Materials and Methods: The study included 583 patients referred for routine dental care. A total of 1125 endodontically treated teet...

OBJECTIVES To determine the health status of periradicular tissue and the quality of root canal fillings in an adult Saudi population attending dental clinics for the first time. Methods: This cross sectional study was conducted  in the dental clinics at King Saud University, Riyadh and other dental centers (Jeddah, Najran, and Albaha City), Kingdom of Saudi Arabia between year 2010   and 2012....

INTRODUCTION The purpose of this study was to investigate the effectiveness of basic root canal treatment (BRT) with tactile working length determination in terms of radiographic and clinical outcome parameters compared with endodontic treatment with standard radiographic working length control. METHODS This was a clinical, multicenter, controlled, open-label trial to evaluate BRT effectivene...

AIM A cross-sectional radiographic orthopantomogram (OPG) survey was done to determine the prevalence of apical periodontitis (AP) in root canal-treated teeth in a selected population, and to evaluate the influence of the coronal restorations (CR) and root canal fillings on the periapical status. MATERIALS AND METHODS A total of 250 OPGs were evaluated out of which root canal treatment (RCT) ...

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...

The present study was conducted to determine the influence of 2 intracanal medicaments (calcium hydroxide, chlorhexidine gel 2%) when used either alone or combined on the short- and long-term sealing ability of permanent root canal fillings. Ninety human upper central incisors were divided into 4 experimental groups (n=20). All root canals were instrumented in a step-back motion and then treate...

AIM To evaluate the technical quality of root fillings performed in the undergraduate clinic of the Dental College, King Saud University, Saudi Arabia and to compare the technical quality of root canal treatment between the 4th- and 5th-year students. METHODOLOGY A random sample of 710 records of patients who had received dental treatment by undergraduate students at the College of Dentistry ...
