INTRODUCTION This study aimed to compare the cytotoxicity of MTA Fillapex, AH-26 and Apatite root canal sealers at different times after mixing. METHODS AND MATERIALS In this in vitro study, MTA Fillapex, AH-26 and Apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. Then, human fetal foreskin fibroblast cell line (HFFF2) were added to each sealer cell culture me...

Perioperative blood loss during total hip arthroplasty (THA) increases patient morbidity, length of stay (LOS), medical resource use (MRU), and costs. Minimizing blood loss may reduce postoperative anemia, the need for blood transfusions, and the increased risk of infections and longer hospital stays associated with blood transfusions. Pharmacologic agents and bipolar sealer devices can minimiz...

INTRODUCTION: Antibacterial properties of nanoparticles have recently come into the spotlight in endodontic therapy. OBJECTIVES: Evaluation of the antimicrobial efficacy of zinc oxide based sealer incorporated with silver and zinc oxide nanoparticles compared with simple zinc oxide sealer against Enterococcus faecalis. MATERIALS AND METHODS: The study was conducted on 60 human extracted mandibu...

It is an "in vitro" study to evaluate the sealing ability of 3 root canal sealers using a dye leakage/clearing method. 40 lower incisors were instrumented by step-back technique and divided into 4 groups. The teeth filled with lateral condensation guta-percha varying sealer. Fill Canal, Sealer 26, N-Rickert tested compared control group in which guttapercha cones no seater used. Linear penetrat...

background: sealing ability is one of the most important features of endodontic sealers. the purpose of this in vitro study was to compare the sealing ability of a resin-based sealer with a mineral trioxide aggregate-based sealer. materials and methods: a total of 60 single-rooted extracted human teeth were randomly divided into two experimental groups (n = 25) and two control groups (n = 5). a...

AIM In an effort to control postoperative sensitivity, dentin sealers are being applied following crown preparations, with little knowledge of how crown retention might be affected. A previous study demonstrated no adverse effect when using a gluteraldehyde-based sealer, and existing studies have shown conflicting results for resin-based products. This study determined the retention of the cast...

OBJECTIVES The purpose of this in vitro study was to evaluate gaps or voids occurring in roots filled with three different sealers. METHODS Thirty extracted human single-rooted teeth were decoronated, instrumented using NiTi rotary instruments, divided into three groups (n=10 per group) and obturated with one of the following: Epiphany with Resilon, MetaSEAL with gutta-percha or AH Plus with ...

We investigated the use of India ink as an indicator of root canal sealing ability. Sealing ability is one of the most important factors required of root canal cements. Various dyes have been used for this purpose. Methylene blue, radioisotopes and India ink have all been tried. However, there is no evidence that India ink is suitable as an indicator. We measured the particle size distribution ...

OBJECTIVE This study assessed the biocompatibility of the Epiphany endodontic sealer prepared with resinous solvent of Epiphany system (Thinning resin) in rat subcutaneous tissues. STUDY DESIGN Polyethylene tubes were filled with the sealer and 4 groups were established: GI, Epiphany prepared with 1 drop of resinous solvent (RS); GII, Epiphany prepared with 1 drop of RS and photoactivated; GI...

The objective of this study was to compare the adaptation of mechanically softened gutta-percha to the root canal wall in the presence and absence of smear layer. The root canals of 20 freshly extracted human maxillary incisors were cleaned and shaped. Prior to obturation, 10 root canals were irrigated with 20 ml of 50% citric acid followed by 20 ml of 5.25% sodium hypochlorite. All canals were...
