UNLABELLED The aim of the present study was to compare, clinically and radiographically, the mineral trioxide aggregate (MTA) to formocresol (FC) when used as medicaments in pulpotomized vital human primary molars. METHODS The sample consisted of 120 primary molars, all teeth were treated with the same conventional pulpotomy technique. Sixty molars received FC and 60 received MTA throughout a...

INTRODUCTION The aim of this study was to evaluate MTA Plus (Prevest Denpro Limited, Jammu, India, for Avalon Biomed Inc) material's properties, namely calcium release, the pH change, solubility, water sorption, porosity, surface morphology, and apatite-forming ability after immersion in simulated body fluid. METHODS Two tricalcium silicate powders (MTA Plus and ProRoot MTA; Dentsply Tulsa Sp...

BACKGROUND AND PURPOSE Medial temporal lobe atrophy (MTA) is a hallmark of Alzheimer disease (AD). Its progression is often seen during the course of AD, but its frequency and risk factors remain unclear. METHODS We investigated MTA in 35 patients with AD from whom sequential magnetic resonance imaging scans were available. White matter lesions (WML; for the periventricular [PV] and subcortic...

AIM This was to carry out a review of the literature concerning mineral trioxide aggregate (MTA) and Portland cement with regards to clinical, biological and mechanical findings and a possible substitution of MTA through Portland cement for endodontic use. STUDY DESIGN Electronic literature search of scientific papers from January 1993 to January 2009 was carried out on the MEDLINE and Scopus...

OBJECTIVES The aim of this study was to evaluate the cytotoxicity, setting time and compressive strength of MTA and two novel tricalcium silicate-based endodontic materials, Bioaggregate (BA) and Biodentine (BD). MATERIALS AND METHODS Cytotoxicity was evaluated by using a 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-((phenylamino)carbonyl)-2H-tetrazolium hydroxide (XTT) assay. Measurements of 9...

OBJECTIVES The purpose of this study was to evaluate in vitro cytotoxicity of the pozzolan cement and other root-end filling materials using human periodontal ligament cell. MATERIALS AND METHODS Endocem (Maruchi), white ProRoot MTA (Dentsply), white Angelus MTA (Angelus), and Super EBA (Bosworth Co.) were tested after set completely in an incubator at 37℃ for 7 days, Endocem was tested in tw...

AIM To compare the mineralization inductive capacity of Biodentine and Bioaggregate with Mineral trioxide aggregate (MTA) and to investigate possible signaling pathways of mineralization in human dental pulp cells (HDPCs). METHODOLOGY Viability of HDPCs in response to Biodentine, Bioaggregate, and MTA was measured using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide. To investig...

We applied the hippocampal radial atrophy mapping technique to the baseline and follow-up magnetic resonance image data of 169 amnestic mild cognitive impairment (MCI) participants in the imaging arm of the Alzheimer's Disease Cooperative Study MCI Donepezil/Vitamin E trial. Sixty percent of the subjects with none to mild hippocampal atrophy rated with the visual medial temporal atrophy rating ...

INTRODUCTION Mineral trioxide aggregate (MTA) is a therapeutic, endodontic repair material that is reported to exhibit calcified tissue-conductive activity although the mechanisms remain unclear. We hypothesize that the dissolution of calcium from MTA into the surrounding environment may play an important role in the osteoblastic/cementoblastic differentiation of human periodontal ligament cell...

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...
