The aim of this study was to evaluate the effects of different root canal filling techniques on the bond strength of epoxy resin-based sealers. Sixty single-rooted canines were prepared using ProTaper (F5) and divided into the following groups based on the root filling technique: Lateral Compaction (LC), Single Cone (SC), and Tagger Hybrid Technique (THT). The following subgroups (n = 10) were ...

The effect of Super-EBA cement as a root-end filling placed in teeth before replantation was examined in eight molar roots in monkeys. After extraction, root ends were resected, the canals contaminated with oral bacteria, root-end cavities prepared, and fillings of Super-EBA placed before replantation. After 8 wk, the jaws were removed and prepared for histological examination. The tissue respo...

UNLABELLED Calcium oxide, available for decades as a root canal filling material, has been little used in recent years due to its lack of radio-opacity, and an expectation that it would lead to an excess of root fractures. In this study, four general dentists submitted 79 cases of endodontically treated teeth whose roots were filled with either Biocalex 6/9, or Endocal-10, and rendered adequate...

AIM To investigate the effect of the radiographic and clinical quality of coronal restorations on the composition of the root canal flora of teeth with necrotic pulps and teeth with root fillings associated with apical periodontitis. METHODOLOGY Twenty-eight necrotic pulps and 35 root filled canals with signs of apical periodontitis were studied. Both the coronal filling (presence of radiogra...

BACKGROUND Obtaining a correct working length is critical to the success of endodontic therapy. Different methods have been used to identify this crucial measurement. The Aim of this clinical study was to compare the effect of working length determination using apex locator alone or in combination with working length radiograph on the apical extent of root canal filling. METHODS A total numbe...

this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic tr...

The most-popular root canal filling materials for primary teeth are zinc oxide eugenol (ZOE), iodoform paste, and calcium hydroxide. Root canal filling materials need to be biocompatible with the periapical tissue. There are few papers which indicate the mechanism of cellular change of root canal filling materials. The purpose of the present study was to evaluate the cellular changes of a ZOE w...

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...

AIM To investigate the quality of root fillings and coronal restorations and their association with periapical status in an adult Spanish population. METHODOLOGY A total of 180 subjects, aged 37.1 +/- 15.7 years, who presented as new patients at the Faculty of Dentistry, Seville, Spain, were examined. All participants underwent a full-mouth radiographic survey incorporating 14 periapical radi...

Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop...
