Comparison of the sealing ability of apical plug materials in simulated open apices: An in vitro study

PURPOSE The aim of this study was to evaluate the microleakage of apical plugs made of four different materials in simulated immature teeth. METHODS Ninety extracted single-rooted teeth were selected and randomly divided into six groups according to the materials used: NeoMTA, EndoSequence Bioceramic Root Repair Material Fast Set Putty (BC RRMFS), Biodentine, Endo Repair, […]

Push-out bond strength of MTA with antiwashout gel or resins

ABSTRACT INTRODUCTION: This study’s aim was to make an assessment of the push-out bond strength of four MTA-based formulations for use as root-end filling materials. METHODS: MTA Plus mixed with (i) water (‘MTA-W’); (ii) a proprietary water-based antiwashout gel (‘MTA-AW’); (iii) Superbond C&B chemically curing resin (‘MTA-Chem’); and (iv) Heliobond light-curing resin (‘MTA-Light’) was tested.

Evaluation of compressive strength of hydraulic silicate-based root-end filling materials

ABSTRACT INTRODUCTION: Hydraulic silicate cements such as mineral trioxide aggregate (MTA) have many clinical advantages. Newer hydraulic silicate materials have been developed that improve on the limitations of mineral trioxide aggregate such as the long setting time and difficult handling characteristics. The purpose of this study was to examine the effect of saline and fetal […]

The effect of root dentin conditioning protocols on the push-out bond strength of three calcium silicate sealers

ABSTRACT INTRODUCTION: The objective was to compare the effects of irrigation protocols on the push-out bond strength of calcium silicate materials at two different time periods (7-days and 3-months). METHODS: Root canals (n=300) were irrigated with one of the following (n=60): group 1 (3% NaOCl–17% EDTA); group 2 (17% EDTA–3% NaOCl); group 3 (1:1 mixture […]

Fracture Resistance of Teeth with Simulated Perforating Internal Resorption Cavities Repaired with Different Calcium Silicate-based Cements and Backfilling Materials

Abstract: This study assessed the fracture resistance (FR) of teeth with simulated perforating internal resorption cavities repaired with different calcium silicate-based cements (CSCs) and backfilling materials. METHODOLOGY: Ninety-six mandibular premolar teeth were used. Twelve of the teeth were assigned as negative control group. Remaining roots were instrumented with rotary files, and standardized internal resorption cavities […]
