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...

INTRODUCTION Retreatment is performed in teeth with unsuccessful root canal therapy or persistent apical lesion. The most important factor for achieving successful retreatment is thorough cleaning and reshaping. NiTi files and rotary instruments are widely used for the removal of obturatants. This study compared the ability of Mtwo and D-RaCe retreatment systems to remove residual gutta-percha ...

Background Complete seal at dentin-sealer-core interface of the root canal is required to maintain long-term periapical health. Aim The aim of this in vitro scanning electron microscopic (SEM) study was to determine which of the commonly used root canal sealer among AH-Plus, GuttaFlow, and RealSeal provides a superior marginal adaptation with the dentin in the apical third region of root cana...

Hydroxyapatite (HA) is the most thermodynamically synthetic calcium phosphate cement, and has indicated useful as a sealer because can seal a furcation perforation, is shown to be biocompatible and also has potential to promote the healing of bone in endodontic therapy. The objective of this study is to determine the sealing ability of HA produced by School of Engineering, Universiti Sains Mala...

INTRODUCTION The function of root canal fillings is to seal the root canal system. The important physical property necessary for sealers to achieve this is low solubility. However, any therapeutic effect of calcium hydroxide-based sealers is dependent on the calcium hydroxide being in ionized form, which implies that the material must be at least partly soluble. OBJECTIVE The objective of our...

INTRODUCTION Adequate root canal seal following retreatment is essential for a successful outcome. Resilon/Epiphany (R/E) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. This in vitro study compared the amount of apical microleakage of R/E with gutta-percha/AH26 (GP/AH26) sealer as secondary root canal filling following retreatment in human tee...

INTRODUCTION The aim of this study was to evaluate the effect of intra-canal calcium hydroxide (CH) remnants after ultrasonic irrigation and hand file removal on the push out bond strength of AH-26 and EndoSequence Bioceramic sealer (BC Sealer). METHODS AND MATERIALS A total of 102 single-rooted extracted human teeth were used in this study. After root canal preparation up to 35/0.04 Mtwo rot...

OBJECTIVE The aim of this study was to evaluate the influence of apical foramen widening on the healing of chronic periapical lesions in dogs' teeth after root canal filling with Sealer 26 or Endomethasone. STUDY DESIGN Forty root canals of dogs' teeth were used. After pulp extirpation, the canals were exposed to the oral cavity for 180 days for induction of periapical lesions, and then instr...

OBJECTIVES The aim of the present study was to investigate the effects of root canal sealers on the cytotoxicity of 3T3 fibroblasts during a period of 5 weeks. MATERIAL AND METHODS Fibroblasts (3T3, 1×105 cells per well) were incubated with elutes of fresh specimens from eight root canal sealers (AH Plus, Epiphany, Endomethasone N, EndoREZ, MTA Fillapex, Pulp Canal Sealer EWT, RoekoSeal and S...
