A chemical activity evaluation of two dental calcium silicate-based materials

Abstract

Calcium silicate-based materials are interesting products widely used in dentistry. The study was designed to compare the chemical reaction between analyzed two preparates and dentin during cavity lining. In our work, dentinal discs were prepared from human extracted teeth filled with Biodentine and MTA+. The samples were then analyzed by way of SEM, EDS and Raman spectroscopy. The obtained results revealed differences in elemental composition between both materials. Biodentine showed higher activity in contact with dentine. Moreover, the interfacial layer in the tooth filled by Biodentine was wider than that in the tooth filled with MTA+. The applied methods of analysis confirmed that both materials have a bioactive potential which is a promising ability.

Efficacy of different calcium silicate materials as pulp-capping agents: Randomized clinical trial

“… 24 However, only a few studies have investigated the clinical efficacy of this MTA+. 16 In this study, MTA+ demonstrated a success rate of 86% after 36 months, which was similar to most studies performed with conventional MTA. In addition, all of the calcium silicate derivatives were found to be better than the calcium hydroxide preparations in both clinical and radiographic examinations.…”

“… 21 In this manner, bioceramics have been produced, necessitating the revision and/or modification of traditional MTA. 14 , 16 , 22 Nanoparticle insertion to the base of conventional MTA facilitates preparation and increases the sealing process, strength, elasticity and homogeneity of the material. In this study, two novel modified calcium silicate materials as well as calcium hydroxide materials were used as pulp-capping agents and were evaluated in terms of sealing, restoring the vitality of the pulp and inducing the DBF.…”

“…MTA+ (Bio MTA) is a similar material to conventional MTA but is modified with the insertion of nanoceramic particles (2%) and hydroxyapatite ingredients (2%) and by decreasing the size of the grains (33%). 16 These particles are three times smaller than the smallest particles of conventional MTA, which provides penetration of calcium ions to the demineralized tissue; facilitates packing material in the application site; increases the sealing process, strength and homogeneity; and reduces the setting time. 16 …”

Endodontium — together or separately?

“…The studies of other authors have shown similar effects of MTA when used to cover pulp directly [13]. In both groups, total dentin bridge formation was observed and no pulp inflammation was present, suggesting Biodentine as an alternative to MTA [4,5].…”
