Hydraulic cements and hardened materials obtained after hydration of the hydraulic cements, especially cements useful in the medical field such as dental cements. In particular, a hydraulic cement including calcium silicate particles and calcium carbonate particles having specific particles sizes. The hydration of the hydraulic cement enables to provide a hardened composite material with reinforcing properties, having calcium silicate particles dispersed in a solid dispersant phase including calcium silicate hydrates (CSH) and porous intergranular areas including insoluble calcium carbonate particles having a d.sub.50 granulometry ranging from 1 nm to 1500 nm.

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler A, phyllo silicate(s), Paste B comprising water, poly-acid, non acid-reactive filler B, optionally chelating agent. The invention also relates to a hardenable composition obtainable by combining the pastes of the kit or parts and to the use of such a composition as or for preparing a dental cement, dental filling mater ial, dental core build up material or dental root channel filling material.

The present invention relates to dental cement composition that is more biocompatible and stimulates quicker healing of the damaged dental tissues. Specifically, the invention relates to dental cement composition comprising a combination of dental repair compounds consisting of nanoparticles of Tri-calcium Silicate (Ca3SiO5), Di-calcium Silicate (Ca2SiO4), Calcium Titanate (CaTiO3) and Hydroxyapatite (Ca10(PO4)6(OH)2).

The present invention relates to: composition for differentiating non-dental mesenchymal stem cells into odontoblasts comprising CPNE7 protein or gene; method for differentiating in vitro non-dental mesenchymal stem cells using the same; and also use thereof.

Provided is a dental investment that is a dental phosphate-bonded investment including boron nitride at 0.1% to 5% by weight.
