TL;DR: This review article focuses on various physical properties of the material with subheadings and continues with biocompatibility, and includes the review of studies on Biodentine as a vital pulp treatment material.
Abstract: Biodentine is a calcium-silicate based material that has drawn attention in recent years and has been advocated to be used in various clinical applications, such as root perforations, apexification, resorptions, retrograde fillings, pulp capping procedures, and dentine replacement. There has been considerable research performed on this material since its launching; however, there is scarce number of review articles that collates information and data obtained from these studies. Therefore, this review article was prepared to provide the reader with a general picture regarding the findings about various characteristics of the material. The results of a PubMed search were classified and presented along with some critical comments where necessary. The review initially focuses on various physical properties of the material with subheadings and continues with biocompatibility. Another section includes the review of studies on Biodentine as a vital pulp treatment material and the article is finalized with the summary of some case reports where the material has been used.

TL;DR: Biodentine and NeoMTA Plus did not show a significant reduction in compressive strength when exposed to NaOCl, and EDTA reduced theCompressive strength of the cements tested.
Abstract: The aim of this study was to evaluate the effect of root canal irrigants on the compressive strength of hydraulic tricalcium silicate cements. 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 one of the solutions (n = 20): Phosphate buffered saline (PBS; control), 3 % NaOCl, or 17 % EDTA for 5 min while being suspended in PBS. Compressive strength values were evaluated after 7 days of storage. The data were statistically analyzed by two-way ANOVA and Tukey’s multiple comparison test (P = 0.05). Biodentine (BD) showed significantly higher compressive strength than the other materials (P < 0.05) in the control group. When exposed to NaOCl, compressive strength of WMTA and WMTA-A decreased significantly (P < 0.05), while EDTA decreased the compressive strength of all the cements compared to the control (P < 0.05). There was no significant difference in the compressive strength of BD and NMTA-P when exposed to NaOCl or EDTA. Biodentine and NeoMTA Plus did not show a significant reduction in compressive strength when exposed to NaOCl. EDTA reduced the compressive strength of the cements tested. Tricalcium silicates were differentially influenced by root canal irrigants. It is essential to understand the composition of these materials prior to clinical use. Traces of irrigants from the root canal wall must be thoroughly removed.

TL;DR: Considering the superior physical and biologic properties, Biodentine™ could be an efficient alternative to MTA to be used in a variety of clinical applications.
Abstract: Introduction Biodentine TM is a new version of calcium silicate-based inorganic cement. Aim The aim of this review is to provide a detailed analysis of the physical and biological properties of Biodentine TM and to compare these properties with those of other tricalcium silicate cements viz. mineral trioxide aggregate (MTA) and Bioaggregate TM (Bioaggregate). Study design A comprehensive systematic literature search for all publications to date was performed on 20th November 2013 by two independent reviewers in Medline (PubMed), Embase, Web of Science, CENTRAL (Cochrane), SIGLE, SciELO, Scopus, Lilacs and clinicaltrials.gov using the search terms Biodentine, ‘‘tricalcium silicate’’, Ca3SiO5, ‘‘dentine substitute’’, ‘‘dentin substitute’’ and RD 94. In addition to the electronic search, hand searches and reference searches were performed to include articles published in journals that were not indexed in Medline. Randomised control trials (RCT), case control studies, case series, case reports, in vitro studies, animal studies and short communications in English language were considered for this review. Conclusions Considering the superior physical and biologic properties, Biodentine TM could be an efficient alternative to MTA to be used in a variety of clinical applications. There appears to be a wide range of clinical applications where Biodentine TM could be used in the field of endodontics, dental traumatology, restorative dentistry and pediatric dentistry. Although it seems to be good clinical practice, currently there is little clinical evidence to support all potential indications.

TL;DR: The properties of MTA and Biodentine are compared analyzing the research work done in this field so far by various researchers all across the globe.
Abstract: An ideal dental repair material should possess certain exclusive properties such as adequate adhesive ability, insolubility, dimensional stability, biocompatibility, bioactivity etc. New materials claiming better performance are continuously being introduced in the market to optimize the care of dental patients. Biodentine has been recently introduced as the "the first all-in-one, bioactive and biocompatible material for damaged dentin replacement". Manufacturers claim that Biodentine has noticeably shorter setting time in contrast to other silicate cements such as Mineral Trioxide Aggregate (MTA) and also has better mechanical and handling properties. This article is aimed to compare the properties of MTA and Biodentine analyzing the research work done in this field so far by various researchers all across the globe.

TL;DR: In this paper, a structure refinement method was described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram.
Abstract: A structure refinement method is described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram. Nuclear as well as magnetic structures can be refined, the latter only when their magnetic unit cell is equal to, or a multiple of, the nuclear cell. The least-squares refinement procedure allows, with a simple code, the introduction of linear or quadratic constraints between the parameters.

TL;DR: White MTA was deficient in alumina suggesting that the material was not prepared in a rotary kiln, and the microstructure of hydrated MTA would likely be weaker when compared with that of PC.
Abstract: Camilleri J. Hydration mechanisms of mineral trioxide aggregate. International Endodontic Journal, 40, 462–470, 2007. Aim To report the hydration mechanism of white mineral trioxide aggregate (White MTA, Dentsply, Tulsa Dental Products, Tulsa, OK, USA). Methodology The chemical constitution of white MTA was studied by viewing the powder in polished sections under the scanning electron microscope (SEM). The hydration of both white MTA and white Portland cement (PC) was studied by characterizing cement hydrates viewed under the SEM, plotting atomic ratios, performing quantitative energy dispersive analyses with X-ray (EDAX) and by calculation of the amount of anhydrousclinkermineralsusingtheBoguecalculation. Results Un-hydrated MTA was composed of impure tri-calcium and di-calcium silicate and bismuth oxide. The aluminate phase was scarce. On hydration the white PC produced a dense structure made up of calcium silicate hydrate, calcium hydroxide, monosulphate and ettringite as the main hydration products. The un-reacted cement grain was coated with a layer of hydrated cement. In contrast MTA produced a porous structure on hydration. Levels of ettringite and monosulphate were low. Bismuth oxide was present as un-reacted powder but also incorporated with the calcium silicate hydrate. Conclusions White MTA was deficient in alumina suggesting that the material was not prepared in a rotary kiln. On hydration this affected the production of ettringite and monosulphate usually formed on hydration of PC. The bismuth affected the hydration mechanism of MTA; it formed part of the structure of C-S-H and also affected the precipitation of calcium hydroxide in the hydrated paste. The microstructure of hydrated MTA would likely be weaker when compared with that of PC.

TL;DR: The hydration mechanism of MTA is different to that of Portland cement; in MTA the bismuth oxide is bound to the C-S-H and is leached out from the cement with time as the C/S-h decomposes, and the release of calcium ions reduces with time.
Abstract: Objective To characterize the hydration products of white mineral trioxide aggregate (MTA). Methodology Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X-ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un-hydrated and after hydration and curing for 30 days at 37 °C. Analysis of hydrated cement leachate was performed weekly for five consecutive weeks from mixing using inductively coupled plasma atomic emission spectroscopy after which the cements were viewed under the scanning electron microscope to evaluate the cement microstructure. Quantitative energy dispersive analysis with X-ray was performed and atomic ratios were plotted. Results Both Portland cement and MTA produced calcium silicate hydrate (C-S-H) and calcium hydroxide (CH) on hydration. The tricalcium aluminate levels were low for MTA which resulted in reduced production of ettringite and monosulphate. On hydration the bismuth level in the hydrated MTA decreased; bismuth oxide replaced the silica in the C-S-H and was leached out once the C-S-H decomposed with time. Both MTA and Portland cement released a high amount of calcium ions which decreased in amount over the 5-week period. Conclusions The hydration mechanism of MTA is different to that of Portland cement. In MTA the bismuth oxide is bound to the C-S-H and is leached out from the cement with time as the C-S-H decomposes. MTA produces a high proportion of calcium ions from CH a by-product of hydration and also by decomposition of C-S-H. The release of calcium ions reduces with time.

TL;DR: Both Biodentine and MTA caused the uptake of Ca and Si in the adjacent root canal dentine in the presence of PBS, and the dentine element uptake was more prominent for BiodENTine than MTA.
Abstract: Han L, Okiji T. Uptake of calcium and silicon released from calcium silicate–based endodontic materials into root canal dentine. International Endodontic Journal. Aim To compare Biodentine and White ProRoot mineral trioxide aggregate (MTA) with regard to Ca and Si uptake by adjacent root canal dentine in the presence of phosphate-buffered saline (PBS). Methodology Root canals of bovine incisor root segments were instrumented, filled with either Biodentine or MTA (n = 20 each) and then immersed in Ca-and Mg-free PBS for 1, 7, 30 or 90 days (n =5 each). Unfilled, unimmersed dentine specimens (n =5 ) served as controls. The specimens were sectioned longitudinally, and the ultrastructure of the dentine‐ material interface and the elemental composition/ distribution in the material‐adjacent dentine were analysed using a wavelength-dispersive X-ray spectroscopy electron probe microanalyser with image observation function. Data were statistically analyzed using one-way anova and Tukey’s honestly significant difference test or the Mann‐Whitney U-test. Results Along the material‐dentine interface, both materials formed a tag-like structure that was composed of either Ca- and P-rich crystalline deposits or the material itself. The width of a Ca- and Si-rich layer detected along the dentine layer of the material‐ dentine interface showed increases over time. The Caand Si-rich layer width was significantly larger (P < 0.05) in Biodentine than MTA at 30 and 90 days. Conclusions Both Biodentine and MTA caused the uptake of Ca and Si in the adjacent root canal dentine in the presence of PBS. The dentine element uptake was more prominent for Biodentine than MTA.
