Apparatus for evacuation of root canal

In an endodontic procedure, after the working of a root canal by instruments to remove material and shape the walls of the canal, irrigant is supplied via a microcannula. A vacuum is applied via a tube which is inserted partway down the root canal. The tube and microcannula pass through a material created by a standard dental filling material of a composite nature Which provides a seal at a position near the top of the coronal opening. The irrigant is supplied in a manner sufficient to ensure delivery to a side vent of the microcannula. The vacuum at the end of tube draws the irrigant and debris up from the apex of the root canal into the tube. The side vent may have a plurality of more round holes, a diagonal slit or a U shaped slit, or any other shape. The vent opening should not extend more than approximately 0.75 mm from the closed spherical tip of the microcannula, it must be burr free any the opening must be smaller than the internal diameter of the microcannula.

Preparation method of low-volume-shrinkage antibacterial dental resin composite material

The invention discloses a preparation method of a low-volume-shrinkage antibacterial dental resin composite material. The preparation method comprises the following steps: mixing and stirring bifunctional acrylate resin and phosphoryl-containing acrylate resin to obtain a dental resin solution; adding a silver source compound, and mixing uniformly with a photoinitiator after the silver source compound is dissolved; then adding an inorganic filler; and finally, injecting into a mold, and irradiating by adopting blue light or ultraviolet light. According to the preparation method disclosed by the invention, a bisphenol monomer with rigid radicals is adopted to prepare a dental resin monomer to reduce the volume shrinkage during curing of a material, and bidirectional amphipathic molecules containing phosphonyl and unsaturated double-bond functional groups are used as a surface modifying agent to ensure that on the one hand, the interface action between the resin and the inorganic filler is improved, and on the other hand, by virtue of the complexing action between the phosphonyl functional groups and silver ions, the silver source compound is dissolved, the process of releasing nano silver is controlled, and a long-acting antibacterial effect is achieved, so that a dental filling material which has low volume shrinkage, excellent mechanical property and antibacterial effect is prepared.
