Gutta percha points的意思

"Gutta percha points" refers to a type of material used in endodontic (root canal) therapy. Endodontic points are small, cone-shaped instruments that are used to fill and seal the root canals of teeth after the pulp has been removed. Gutta percha is a natural rubber that is often used in this context because it can be easily molded and shaped to fit the specific contours of the root canal, and it is also impervious to bacteria and able to withstand the forces of chewing.

During an endodontic procedure, the root canal is cleaned and shaped to remove any infection or debris. Once the canal is prepared, gutta percha points are heated and then compacted into the canal to serve as a sealant. The points are typically used in conjunction with an endodontic sealer, which helps to fill any microscopic spaces and further seal the canal.

Gutta percha points are a common and effective material for root canal filling because they provide a tight, durable seal that can help to prevent reinfection of the tooth and preserve the tooth's function.
