A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

A cement system for forming an implant comprises a reactive glass ionomer cement (GIC) powder, a polycarboxylic acid or salt, and a filler. The polycarboxylic acid or salt is included to initially provide a paste having a pH less than 7 when the cement system is mixed with water. In one embodiment, the filler is substantially inert when mixed with water and is selected from (CaO)(AI.sub.2O.sub.3)6, (CaO)(AI.sub.2O.sub.3).sub.2, calcium silicate (CaOSiO.sub.2), and mixtures thereof. In another embodiment, the filler is substantially reactive when mixed with water and is selected from (CaO).sub.2(SiO.sub.2), (CaO).sub.3(SiO.sub.2), and mixtures thereof, and the cement system includes an additional acid to maintain the paste at a pH less than 7 for at least one hour after the cement system is mixed with water.

Provided is a formulation for oral teeth, which includes a plurality of calcium ion carriers and a plurality of calcium-containing particulates. The particulates are carried by the calcium ion carriers, such that the formulation can prevent or rapidly treat dentin-associated symptoms or diseases, while providing a prolonged prophylactic or therapeutic effect.

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.
