OBJECTIVES To evaluate the effect of root canal sealers (RCS) and specimen aging on the bond strength of fibre posts to bovine intraradicular dentin. MATERIAL AND METHODS 80 teeth were used according the groups - Sealapextm, Sealer 26®, AH Plus® and specimens aging - test with no aging and with aging. The canals prepared were filled using one of each RCS. The posts were cemented. Roots were cr...

Objective: The purpose of this study was to use confocal laser microscopy analysis evaluate the effectiveness conventional needle irrigation (CNI), EndoActivator (EA), and EDDY during endodontic retreatment.
 Methods: This included 45 maxillary incisor teeth with a single root canal. Root canals were prepared ProTaper Universal files (Dentsply Sirona, Ballaigues, Switzerland) obturated lab...

PURPOSE To investigate whether the placement of a methacrylate root canal sealer or a conventional epoxy root canal sealer in two steps increases their dislocation resistance when compared to a one-step placement procedure. MATERIALS AND METHODS Eighty single-rooted teeth were randomly allocated to 4 groups (n=20). All canals were instrumented to size 40, 0.06 taper and irrigated according to...

OBJECTIVE The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with - Tubli-Seal EWT/Gutta-percha, AH Plus/Gutta-percha, Epiphany SE sealer/Epiphany point. STUDY DESIGN Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen. Fifty five teeth were enlarged up to ISO size 40 master api...

Coronal leakage is an important factor affecting the outcome of endodontic therapy. This study evaluated the microbial leakage (ML) and the apical inflammatory response (AIR) in dog's teeth after root canal filling with three endodontic sealers, post preparation and exposure to the oral environment, testing the hypothesis that there is a positive correlation between these two histological param...

This case report describes root canal filling performed over a large S1 ProTaper file fragment in a second mandibular molar with irreversible pulpitis. An S1 ProTaper file was fractured during the instrumentation of the mesiobuccal canal. Approximately 10 mm of file fragment remained in the apical and middle thirds of the canal. The obturation was performed over this fragment using thermomechan...

OBJECTIVE The purpose of this study was to introduce a new method for quantitative testing of endodontic leakage. STUDY DESIGN Eighty straight maxillary anterior teeth were divided randomly into 3 experimental groups of 20 samples each and 2 control groups. The experimental groups were prepared using the modified double-flared technique and obturated by lateral compaction of cold gutta-percha...

INTRODUCTION Root canal sealers used in odontological applications are capable of providing an apical seal, thus inhibiting potential bacterial penetration into the periradicular tissues. Since insolubility is the ideal characteristic for a root canal sealer material, in dentistry the sealability of the material depends on its solubility. PURPOSE This study tested the solubility of six differ...

Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...
