摘要:
A system and method for mitigating pain associated with dentistry provides a removal apparatus for removing a portion of a tooth. A desiccation apparatus flows a desiccated gas to the portion of the tooth to desiccate dentinal tubules in a region surrounding the portion of the tooth, generally preventing nerve cells within the tooth from transmitting pain signals associated with the removal. The removal apparatus has a drill head with a body having an axial opening configured to accept a dental burr. An annular passage exists between the dental burr and the body within the axial opening. A chamber in the body is in fluid communication with the axial opening, where a channel is fluidly coupled to an external port and to a source of the desiccated gas to flow the desiccated gas therethrough and expose a drilling region of the dental burr to the desiccated gas to mitigate pain.
