T s e d a c w m bstract his study assessed the apical leakage of ultrasonically ondensed root fillings in extremely large canals, comared to cold lateral condensation and thermoplastic ompaction. Ninety single-rooted teeth were used. In 5 teeth canals were enlarged to size 70 (large). The emaining 45 canals were enlarged to size 140 (exremely large). Each set of teeth was subdivided into hree r...

Objective. The purpose of this study was to radiographically evaluate technical quality of root canal fillings performed by dental undergraduates at Libyan International Medical University in Libya. Methods. Root canal cases were treated at university dental clinic from the fall of 2012 to the fall of 2013 by the fourth and fifth year dental students. Students used step-back preparation and col...

AIM To compare the ability of Ceramicrete, BioAggregate and white ProRoot MTA (mineral trioxide aggregate) to prevent glucose leakage through root-end fillings. METHODOLOGY After root canal instrumentation, the apical 3 mm of maxillary incisors were resected and retropreparations, 3 mm in depth, were created with ultrasound. Root-end cavities were filled with the tested materials (15 roots pe...

The purpose of this study was to determine the different reasons for root canal failure in the department of dentistry at Pakistan Institute of Medical Sciences. It was a cross sectional study which was based on collection and interpretation of data. Seventy patients of both genders were selected from dental out patient department of PIMS. All patients selected, presented with post endodontic c...

The aim of this study was to compare the efficacy of D-RaCe files and a self-adjusting file (SAF) system in removing filling material from curved root canals instrumented and filled with different techniques by using microcomputed tomography (micro-CT). The mesial roots of 20 extracted mandibular first molars were used. Root canals (mesiobuccal and mesiolingual) were instrumented with SAF or Re...

OBJECTIVE The presence of periapical radiolucency has been used as a criterion for endodontic treatment failure. However, in addition to the inherent limitations of radiographic examinations, radiographic interpretations are extremely subjective. Thus, this study investigated the effect of partial analysis of root filling quality and periapical status on retreatment decisions by general dentist...

AIM To investigate the prevalence of apical periodontitis (AP) and root filled teeth found on cone-beam computed tomography (CBCT) scans in a Belgian subpopulation in a retrospective cross-sectional study. METHODOLOGY At the university hospital of Leuven, 804 patients received a CBCT scan between 01/01/2013 and 01/01/2014. The investigated sample included 631 scans with a permanent dentition ...

OBJECTIVE With a microcomputed tomography (microCT) imaging device, we aimed to quantitatively evaluate root canal fillings after commonly used endodontic procedures and also tested the suitability of microCT for this purpose. MATERIALS AND METHODS Eighty single roots were instrumented and obturated with gutta-percha and Tubli-Seal. They were divided into 4 groups of 20. The Hand groups were ...

Strengthening of Resilon-filled roots via an adhesive interface should be reflected by improvement in the interfacial strength and dislocation resistance between the root fillings and intraradicular dentin. This study compared the interfacial strengths of Resilon/Epiphany and gutta-percha/AH Plus using a thin-slice push-out test design. Failure modes of root slices after push-out testing were e...

Despite the advantages of cone-beam computed tomography (CBCT), the images provided by this diagnostic tool can produce artifacts and compromise accurate diagnostic assessment. This paper describes an endodontic treatment of a maxillary molar where CBCT images suggested the presence of a nonexistent third root canal in the palatal root. An endodontic treatment was performed in a first maxillary...
