    • The present invention provides substances, devices, methods, and kits for photo-sterilization of a root canal, prior to and when performing endodontics, as well as periodically as post-endodontic prophylactic measures. The root-canal filling includes a light-transmitting element, operative as a diffuser, and methods are provided for communicating light to the diffuser, for disinfecting the walls of the root canals, by photo sterilization. The diffuser may be formed of silicone polymers, synthetic fused silica, quartz or the like, and may be surrounded by a light-transmitting sealer. The diffuser may be incorporated with an endodontic post, or a specially designed post, which may be transparent and (or) hollow. In a preferred embodiment, the diffuser is formed of a light transmitting conical shell of Cyclic Olefin Copolymers (COC), filled with a fluid such as air, distilled water, or silicone oil.
    • 本发明提供了在进行牙髓治疗之前和期间根管根管的光消毒的物质,装置,方法和试剂盒,以及周期性地作为根治后预防措施。 根管填充物包括作为扩散器操作的透光元件,并且提供了用于将光传播到扩散器的方法,用于通过光杀菌来消毒根管壁。 扩散器可以由硅氧烷聚合物,合成熔融石英,石英等形成,并且可以由透光封闭器包围。 扩散器可以与可以是透明的(或)中空的根管柱或特殊设计的柱结合。 在优选实施例中,扩散器由填充有诸如空气,蒸馏水或硅油的流体的环状烯烃共聚物(COC)的透光锥形壳形成。
