Background: Dentin adhesion is a basic aspect to consider in a root canal sealer. Calcium silicate-based cements are materials that have excellent biocompatibility and bioactivity. Bioactivity is closely related to dentin bond strength. One of the tests that is most used to evaluate the adhesive property of a sealing cement is the "push-out bond …

Calcium silicate is used to insulate high-temperature pipes and equipment and for fire endurance applications. It is manufactured and sold in three different forms: preformed block, preformed pipe, and board. Today's calcium silicate manufactured in North America is noted for its high compressive strength, corrosion-inhibiting properties, …
Calcium Silicate had no discernible effect on nidation or on maternal or fetal survival in rabbits. Magnesium Aluminum Silicate had neither a teratogenic nor adverse effects on …
The bone, being an essential tissue in the human body, not only protects the organs inside the body but also provides mechanical support, haematopoiesis, mineral …
This study aimed to review the considerations for choosing a suitable sealer according to various endodontic scenarios. An electronic search of PubMed, Scopus, and the Web of Science was undertaken for the keywords of 'sealer choosing', 'appropriate sealer', 'suitable sealer', 'sealer for clinical scenario', and 'sealer for clinical situations'. However, the …
The longstanding significance of calcium silicate materials in the built environment cannot be overstated. In addition, a wide range of calcium silicate-based …
The risk of nZVI/biochar was reduced to low risk compared with raw materials. • Oxide scale can be used as a cheap iron source to produce nZVI/biochar composites. • Blast furnace slag protect nZVI from corrosion by forming calcium silicate coating. • Calcium silicate coated-nZVI/biochar shows excellent As(V) removal and …
Other common anti-caking agents include: silicon dioxide, calcium silicate, iron ammonium citrate, and yellow prussiate of soda. Several anti-caking agents have been cause for concern recently because of their name. Sodium and Potassium ferrocyanide are feared because the chemical compound contains cyanide, a known toxin and common …
The aim of the present in vitro study was to evaluate the intratubular penetration of three bioceramic sealers in root canal retreatment. Here, 30 single-rooted human teeth were instrumented with the Protaper Universal system and filled with gutta-percha and the epoxy-resin-based sealerPlus mixed with rhodamine B. After two …
The increase in heavy metal concentration in water bodies due to rapid industrial and socio-economic development significantly threatens ecological and human …
Explore the fascinating world of magnesium silicate, its properties, industrial uses, health impacts, environmental role, and future potential. Magnesium Silicate: An Overview. Magnesium silicate, chemically denoted as Mg 2 SiO 4, is a mineral compound with a rich history and wide range of applications in various industries. It is part of a ...
This review aims to evaluate whether root canal obturation with calcium silicate-based (CSB) sealers reduces the risk and intensity of endodontic postoperative pain when compared to epoxy resin ...
