摘要:
Improved compositions comprising a mixture of gutta-percha and a hydraulic material containing calcium silicate, calcium aluminate, calcium phosphate, and calcium sulfate compounds are provided. Preferably, the composition includes hydroxylapatite mineral. The composition is particularly suitable for obturating and sealing dental root canals. The composition should provide a stable barrier to bacterial and fluid leakage in the root canal system of a tooth. In addition, the composition should help promote the growth of new bone and tissue surrounding the root tip area.
