Effect of root canal irrigating solutions on the compressive strength of tricalcium silicate cements.

Abstract OBJECTIVES: The aim of this study was to evaluate the effect of root canal irrigants on the compressive strength of hydraulic tricalcium silicate cements. MATERIALS AND METHODS: Specimens (n = 60) of tricalcium silicate materials-Group 1: White ProRoot mineral trioxide aggregate (MTA), Group 2: NeoMTA Plus, Group 3: White MTA Angelus, and Group 4: Biodentine were exposed to […]

The effect of root dentin conditioning protocols on the pushout bond strength of three calcium silicate sealers.

ABSTRACT OBJECTIVE: 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). MATERIALS AND 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 of […]

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 […]

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

Abstract Aim: Assessment of the push-out bond strength of four MTA-based formulations for use as root-end filling materials. Methodology: 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 lightcuring resin (‘MTA-Light’) was tested. Root slices 3 mm thick human had […]
