The present invention provides a curable calcium phosphate composition for biological hard tissue repair that yields a cured product excellent in durability in a wet environment such as in a body or an oral cavity. The present invention relates to a curable calcium phosphate composition for biological hard tissue repair, including tetracalcium phosphate particles (A), calcium hydrogen phosphate particles (B), calcium carbonate particles (C), and water (D), the curable calcium phosphate composition including 5 to 75 parts by weight of the tetracalcium phosphate particles (A), 10 to 70 parts by weight of the calcium hydrogen phosphate particles (B), and 2 to 50 parts by weight of the calcium carbonate particles (C) per 100 parts by weight of the total of the tetracalcium phosphate particles (A), the calcium hydrogen phosphate particles (B), and the calcium carbonate particles (C).

This invention provides a non-surgical method for treating periodontitis comprising administering an article into a periodontal pocket, where the article comprises crosslinked collagen and hydroxyapatite. This invention also provides articles to be used within these methods.

A phosphorous compound such as STMP is used as a cross-linking agent while making a starch nanoparticle in an emulsion process. Negative charge of the nanoparticle is reduced or reversed by adding cations and/or cationizing the starch optionally while forming the nanoparticles. Anionic active agents, such as fluoride or fluorescein, are optionally incorporated into the nanoparticle during the formation process. For example, a fluoride salt can also be used, which promotes the crosslinking reaction while also providing fluoride in the nanoparticle. The retention of both calcium and fluoride in the nanoparticle is improved when both salts are used. Alternatively, the nanoparticle may be used without added calcium and/or fluoride. The nanoparticles may be useful for tooth remineralization, the treatment of dentinal hypersensitivity, to treat caries, or as a diagnostic agent to locate carious lesions.

Lithium disilicate apatite glass-ceramics are described which are characterized by a high chemical stability and can therefore be used in particular as restoration material in dentistry.

The present invention relates to the deposition of a micro-crystalline hydroxyapatite and tricalcium phosphate coating onto gutta-percha cones, to be used as dental composite for root canal filling. The method proposed for coating involves the surface pretreatment of gutta-percha cones with sodium hydroxide; immersion of gutta-percha cones in simulated body fluid, which contains calcium and phosphate ions; and replacing consumed simulated body fluid after an interval of time, at physiological pH and temperature. The nucleation process results in the biomimetic deposition of a thin and uniform layer of calcium phosphates and hydroxyapatite. Improved characteristics such as in sealing ability, bonding strength, and ability to form hermetic seal, therefore allows the dental composite produced, to be used appropriately as filling matter in root canal treatments.
