introduction: the aim of this study was to evaluate the apical and coronal sealing of endodontic fillings promoted by the associations of sealer 26/gutta-percha, endofill/gutta-percha and resilon/ epiphany. materials and methods: it was used 38 human canines, 10 teeth for each test group and 4 teeth for each control group. after teeth conventional endodontic treatment, they were immersed in sal...

Background: The objective of three-dimensional obturation is to completely seal the canal system from any bacterial ingress from the oral cavity and periradicular tissues. The aim of the study to compare the push-out bond strength of the smart seal C-point obturating system with epiphany resilon obturation system and the gold standard gutta-percha/AH plus system. Materials and Methods: Thirty e...

The effectiveness of a material to adequately seal the root canal space is related to its physical properties and handling characteristics. Since the introduction of the warm vertical compaction technique, the thermoplastic compaction of canal spaces has been broadly advocated. Warm gutta percha can be easily Rheological characterization of thermoplasticized injectable gutta percha and resilon

UNLABELLED The development and maintenance of the sealing of the root canal system is the key to the success of root canal treatment. The resin-based adhesive material has the potential to reduce the microleakage of the root canal because of its adhesive properties and penetration into dentinal walls. Moreover, the irrigation protocols may have an influence on the adhesiveness of resin-based se...

introduction: the purpose of this study was to evaluate the sealing ability of gray-colored mineral trioxide aggregate (gmta), white-colored mta (wmta), and resilon as root filling materials. materials and methods: sixty-six human maxillary central incisors were used in the present study. in the group a, 20 teeth were filled with gmta. in the group b, 20 teeth were filled with wmta and in the g...

the purpose of this ex- vivo study was to evaluate the fracture resistance of simulated immature teeth, obturated with gutta-percha or resilon and reinforced by either composite resin or fiber post.eighty-four human maxillary incisors were divided into seven groups (n=12). teeth in all groups were prepared until peeso #5 (1.5mm) could be passed through the apex. root ends received 4mm of mta pl...

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 ...

background: reinforcement of root canals obturated with resilon was reported by several investigators, but no studies reported the reinforcement of overtly fl ared root canals obturated with resilon material. the aim of this study was to investigate the fracture resistance of overtly fl ared root canals fi lled with resilon as compared to similar root canals fi lled with gutta-percha (gp). mate...

INTRODUCTION The aim of the present experimental study was to evaluate the push-out bond strength of Dorifill, Epiphany and MTA-Fillapex sealers to root canal dentin in presence and absence of smear layer (SL). METHODS AND MATERIALS Sixty human single-rooted teeth were selected and divided into six groups (n=10). The canal irrigation protocol in groups 1, 3 and 5 consisted of 2.5% NaOCl durin...

INTRODUCTION Vertical root fracture inevitably leads to tooth extraction. Thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. This study aimed to assess the fracture resistance of roots following the application of different sealers including Epiphany, iRoot sealer and AH-plus. METHODS AND MATERI...
