TL;DR: In this paper , the porosity and solubility of the nanoFastCement (NFC) were evaluated at different magnifications (200×, 1000×, 4000×, 6000× and 10000×) in secondary backscattered electron mode.
Abstract: New calcium silicate base cements are introduced as root repair materials in order to defeat the problems of early root repair materials. Their mechanical properties such as solubility and porosity should be concerned.This study was conducted to evaluate the solubility and porosity of the NanoFastCement (NFC) as a new calcium silicate base cement comparing to mineral trioxide aggregate (MTA).In this in vitro study, scanning electron microscope (SEM) was used to evaluate the porosity at five different magnifications (200×, 1000×, 4000×, 6000× and 10000×) in secondary backscattered electron mode. All analyses were performed at 20kV. The obtained images were subjected to qualitative evaluation regarding the porosity. Solubility was determined following the international standards organization (ISO) 6876 method. Twelve specimens in specially fabricated stainless steel ring molds were weighed, initially and after 24 hour and 28 days of immersion in distilled water. Each weight was measured three times to record the average weight. Solubility was measured by calculating the difference of the initial and final weight.Solubility of the NFC in comparison with MTA showed no statistical difference (p Value > 0.05) after one day and 28 days. NFC acted like MTA and showed an acceptable solubility value at exposure time intervals. In both groups, solubility increased as time went on (p Value<0.05). The porosity of NFC was comparable to MTA, and NFC presented a less porous and a slightly smoother surface compared to MTA.NFC has similar solubility and porosity to Proroot MTA. Therefore, it can be a good, more available and less expensive substitute for MTA.
TL;DR: MTA has a pH of 10.2 initially, which rises to 12.5 three hours after mixing, and is more radiopaque than Super-EBA and IRM, and none of the materials tested showed any solubility under the conditions of this study.
TL;DR: Dental polymer networks have been shown to be susceptible to hygroscopic and hydrolytic effects to varying extents dependent upon their chemistry and structure, and these effects on the clinical performance of polymer restoratives is largely unknown.
TL;DR: This in vitro study used rhodamine B fluorescent dye and a confocal microscope to evaluate the sealing ability of amalgam, super EBA, and a mineral trioxide aggregate when used as root end filling materials.
TL;DR: MTA is a bioactive material that influences its surrounding environment and possesses some antibacterial and antifungal properties, depending on its powder-to-liquid ratio.
TL;DR: The authors conclude that Ca, the dominant ion released from mineral trioxide aggregate, reacts with phosphates in synthetic tissue fluid, yielding hydroxyapatite, and the dentin-mineral trioxide aggregation interfacial layer results from a similar reaction.
