AIM To evaluate the outcome of root canal treatment in primary teeth using three root canal filling materials - RC Fill, Vitapex and Pulpdent root canal sealer. METHODOLOGY The study was a single-centre, double-blind, randomized controlled trial carried out on 129 primary mandibular molars with necrotic pulps or irreversible pulpitis in 4- to 9-year-old children. Participants were selected ba...

Successes of endodontic treatment depend on cleaning and shaping of root canal and adequately obturate the prepared root canal space. 1-3 Obturation has historically been achieved with gutta percha and a sealer. The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, anastomoses between canals and a variety of fins. All this leads to...

The aim of this study was to determine the percentage of gutta-percha-filled area (PGFA) in the apical third of root canals after filling with either System B or cold lateral lateral condensation techniques. Sixty-six recently extracted human maxillary central incisors were prepared with ProTaper NiTi rotary files and randomly divided into two groups of 33 teeth each. Root canal obturation was ...

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...

BACKGROUND The aim of this study was to investigate the physical properties and biological effects of an experimentally developed injectable premixed calcium-silicate root canal sealer (Endoseal) in comparison with mineral trioxide aggregate (MTA) and a resin-based sealer (AHplus). METHODS The pH, solubility, dimensional change, flow, and radiopacity of the materials were evaluated. Biocompat...

Introduction: The purpose of this study was to test different sealer removal protocols following root canal filling before adhesive seal of access cavities. Material and methods: Forty single root teeth were selected for the study, prepared to size 60 taper .02, and filled with AH plus and a single gutta-percha cone size 55 taper .02. Excess sealer was removed with: ethanol-moisturised foam pel...

The aim of this study was to investigate apical microleakage after use of the Resilon system in comparison with gutta-percha. The materials used were 54 mesial roots of mandibular molars with an apical curvature of 20-40 degrees . The root canals were instrumented with the Prosystem GT(R) and obturated with: Group I: Gutta-percha + Sealer by lateral condensation (n = 25); Group II: Gutta-percha...

OBJECTIVES The aim of this study was to evaluate tooth discoloration caused by contact with a novel injectable mineral trioxide aggregate (MTA)-based root canal sealer (Endoseal; Maruchi, Wonju, Korea) compared with a widely used resin-based root canal sealer (AHplus; Dentsply De Trey, Konstanz, Germany) and conventional MTA (ProRoot; Dentsply, Tulsa, OK, USA). MATERIALS AND METHODS Forty sta...

The aim of this study was to obtain a quantitative analysis of the film thickness of a root canal sealer formed after filling by three different techniques. Thirty human maxillary incisors were selected and access cavities were prepared using high-speed diamond stones and water spray. A size #15 K-Flexofile was introduced in the canal of each specimen until it was seen just at the apical forame...
