introduction: the purpose of this in vitro study was to investigate the influence of 5.25% sodium hypochlorite (naocl) and 0.12% chlorhexidine gluconate (chx) use separately and combined as endodontic irrigants on the apical sealing ability of two endodontic sealers. materials and methods: eighty-six extracted maxillary central incisor teeth were used. the teeth were decoronated at the cej, acc...

UNLABELLED The aim of this study was to investigate the technical quality of root fillings in root filled teeth, their association with periapical status and prevalence of apical periodontitis. MATERIAL AND METHODS The sample consisted of 83 subjects, presenting consecutively as new patients seeking dental care (prosthetic, endodontic and cariologic treatment) in the years 2005/2006. Clinical...

AIM The aim of this study was to investigate the quality of endodontic and coronal restorations and the association with periapical status in a Danish population. METHODOLOGY A total of 614 randomly selected individuals (20-60+ years of age) from Aarhus County had a full-mouth radiographic examination. The quality of endodontic and coronal restorations and the periapical status of endodontica...

INTRODUCTION Adequate root canal seal following retreatment is essential for a successful outcome. Resilon/Epiphany (R/E) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. This in vitro study compared the amount of apical microleakage of R/E with gutta-percha/AH26 (GP/AH26) sealer as secondary root canal filling following retreatment in human tee...

AIM: The aim of this in vitro study is to determine the push-out bond strength bundle glass fiber post (Rebilda GT) and tapered post). MATERIALS AND METHODS: Twenty freshly extracted human single rooted premolar teeth were used, all endodontically treated, after 24 h from obturation gutta-percha removed leaving 5 mm apically ensure clinically acceptable apical seal. Finally, canals flushed with...

INTRODUCTION An immature tooth with pulpal necrosis and apical periodontitis presents a unique challenge to the endodontist. Endodontic treatment options consist of apexification, apical barriers, or more recently, revascularization. The purpose of this case series is to report three cases that used revascularization protocol as described by Banchs and Trope. Each case presented its own special...

INTRODUCTION This in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (GP) root filling used with either mineral trioxide aggregate (MTA), new endodontic cement (NEC) or AH26 as filler/sealers. MATERIALS AND METHODS Forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. Samples were randomly divided into three experimenta...

Apexification with calcium hydroxide is associated with certain difficulties, such as the very long treatment time required, the possibility of tooth fracture, and incomplete calcification of the bridge. Use of an apical plug is an alternative treatment for open apices, and this has gained popularity in recent years, employing mineral trioxide aggregate (MTA) for optimal results. Here we report...

INTRODUCTION Recently, attention has been drawn to the influence of smear layer removal on apical seal, and the relation of root canal filling material with canal wall surface in the presence and absence of the smear layer. The purpose of this study was to evaluate the influence of the smear layer removal on the apical sealing ability of AH26 sealer. MATERIALS AND METHODS Forty extracted huma...

Tyloses form in xylem vessels in response to various environmental stimuli, but little is known of the kinetics or regulation of their development. Preliminary investigations indicated that wounds seal quickly with tyloses after pruning of grapevine shoots. In this study, tylose development was analyzed qualitatively and quantitatively at different depths and times from pruning cuts along curre...
