OBJECTIVE Handling of endodontic sealers is greatly dependent on their elasticity and flow ability. We compared the viscoelastic properties of three root canal sealers. MATERIALS AND METHODS AH Plus (Dentsply, De Trey, Konstanz, Germany), Endofill (Dentsply Hero, Petrópolis, Rio de Janeiro, Brazil) and AH26 (Dentsply, De Trey, Konstanz, Germany) were mixed according to the manufacturers' inst...

OBJECTIVES Recently, bioceramic sealers like EndoSequence BC Sealer (BC Sealer) have been introduced and are being used in endodontic practice. However, this sealer has limited research related to its retreatability. Hence, the aim of this study was to evaluate the retreatability of two sealers, BC Sealer as compared with AH Plus using micro-computed tomographic (micro-CT) analysis. MATERIALS...

introduction: optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. so, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. materials and methods: in this in vitro study, six endodon...

Assess the antibacterial, physical and chemical properties of AH Plus, BioRoot RCS Pulp Canal Sealer (PCS) in contact with 2% chlorhexidine digluconate (CHX) used as final irrigant prior to root canal obturation. The antimicrobial were investigated by direct tests for planktonic biofilm growth E. faecalis, S. mutans, S.epidermidis S.aureus vitro. setting time, wettability, microhardness surface...

OBJECTIVES The aim of this study was to compare the push-out bond strength and dentinal tubule penetration of root canal sealers used with coated core materials and conventional gutta-percha. MATERIALS AND METHODS A total of 72 single-rooted human mandibular incisors were instrumented with NiTi rotary files with irrigation of 2.5% NaOCl. The smear layer was removed with 17% ethylenediaminetet...

INTRODUCTION Several studies have evaluated the inflammatory reaction triggered by Epiphany (EPH), a contemporary endodontic sealer. However, they used conventional parameters, which need additional analysis to better understand the reactions induced by this sealer compared to other traditional sealers. METHODS AND MATERIALS The intensity and time span of tissue irritations for three endodont...

background: the strong link between sealer solubility and periapical reinfection indicates that water solubility of new sealers should be studied. this study aimed to assess the water solubility of five root canal sealers (ah-26, topseal, 2-seal, acroseal, and roeko seal automix [rsa]). materials and methods: in this in vitro experimental study, 30 specimens were fabricated from each of the abo...
