objectives: mineral trioxide aggregate (mta) is extensively used in endodontics. however, mta is difficult to handle because of its granular consistency, low mechanical properties and initial looseness. the objective of this study was to assess the compressive strength (cs), diametral tensile strength (dts), and ph of set mta using methyl cellulose as liquid. materials and methods: white proroo...

i ntroduction: the aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (dpc) with four different dpc methods/materials. methods and materials: this study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. subsequent to tooth isolation, standardized class i occlu...

Objective Mineral trioxide aggregate (MTA) cements contain two types of particles, namely Portland cement (PC) (nominally 80% w/w) and bismuth oxide (BO) (20%). This study aims to determine the particle size distribution (PSD) of PC and BO found in MTA. Materials and methods The PSDs of ProRoot MTA (MTA-P) and MTA Angelus (MTA-A) powder were determined using laser diffraction, and compared to s...

OBJECTIVE To evaluate the push-out bond strength of Biodentine (BD) in comparison with two available calcium silicate based materials, bioaggregate (BA) and ProRoot MTA (WMTA). MATERIALS AND METHODS One hundred and twenty-three Root dentin slices of freshly extracted single Rooted human teeth were randomly divided into three groups (n = 41) according to the used test material: WMTA, BA, BD. A...

The aim of the present in vitro study was to investigate effects 10% and 40% citric acid (CA) on color calcium silicate–based cements (CSCs) comparison common root canal irrigants. Samples six CSCs (n = 6)—ProRoot MTA (Dentsply, Tulsa, OK, USA), Biodentine (Septodont, Saint-Maur-des-Fossés, France), Plus (Avalon Biomed Inc, by Prevest Denpro Limited, Jammu, India), Repair HP (Angelus, Londrina,...

Background and Aim: The use of ceramics has a long history. A new category of these materials was used in medicine in 1960 introduced as bioceramics. Biocompatibility, osteoinductivity and sealing ability are among the most favorable characteristics of endodontic bioceramics. Introduction of mineral trioxide aggregate (MTA) revolutionized endodontics and this new era is progressively growing. ...
