OBJECTIVES The aim of this study was to evaluate the effect of gutta percha/AH26 and Resilon/RealSeal SE on residual antimicrobial activity of chlorhexidine (CHX) in human root dentin and suggest the best filling material when CHX is used as final irrigant. MATERIALS AND METHODS One-hundred and forty-four single-rooted human teeth were selected for this study. Canals were instrumented to the ...

The purpose of this study was to evaluate the potential of using mineral trioxide aggregate as a root canal filling material by comparing its apical sealing ability with that of laterally condensed gutta-percha with sealer and high-temperature thermoplasticized gutta-percha with sealer in extracted bovine teeth. Sixty bovine incisors with single canals were prepared in a standard manner using L...

BACKGROUND The key to success of any root canal therapy is adequate obturation of the prepared root canal space. Root canal sealers are not dimensionally stable and might dissolve partially over a period of time. The objective of this in vitro study is to evaluate the push-out bond strength to intraradicular dentin of two endodontic obturation materials. MATERIAL AND METHODS Forty extracted s...

Background/Aim. The ability to effectively and consistently penetrate into dentinal tubules is considered as a favorable factor of root canal sealers RCS). aim the study was assess penetration depth three RCS combined with four obturation techniques. Methods. Mesial canals 66 extracted human mandibular molars were endodontically prepared randomly allocated 12 experimental groups depending on se...

Since there are no data in the literature regarding comparison of marginal adaptation hydraulic sealers when used with a single-cone technique or through thermomechanical compaction, this study aimed to evaluate behavior four different endodontic two above-mentioned obturation techniques by evaluating gap existing between materials and dentinal walls scanning electron microscopy. Given objectiv...

AIM   To compare the effectiveness of two Ni-Ti systems and hand files for removing gutta-percha and sealer from root canals. METHODOLOGY   The root canals of 60 single-rooted human teeth were prepared, filled with gutta-percha and sealer (Pulp Canal Sealer; SybronEndo, Orange, CA, USA). Specimens were then divided into three groups (n=20), and root filling material was removed using MTwo Ret...

The quality of apical seal with regard to the length of remaining gutta-percha following post-space preparation is still controversial. The purpose of this in vitro study was to compare three different lengths of remaining gutta-percha for apical seal after post-space preparation. A total of 126 single-rooted extracted maxillary human anterior teeth with intact apices, straight roots, and witho...

This in vitro study compared the ultrastructural quality of the apical seal achieved with Resilon/Epiphany and gutta-percha/AH Plus. Single-rooted extracted human teeth were prepared using a crown-down technique, debrided with NaOCl and EDTA, and obturated with either Resilon/Epiphany or gutta-percha/AH Plus. They were examined for gaps along canal walls using SEM, and for apical leakage using ...
