Abstract: A device for drying a root canal includes a cannula configured to inject a gas stream into the root canal. The cannula is a conduit having a proximal end in fluidic communication with a distal end. A handpiece is configured to removably hold the proximal end of the cannula at a distal handpiece end. A gas stream source is connectable to a proximal end of a tube. A distal end of the tube is connectable to the proximal handpiece end. A cut-off valve is disposed within the handpiece in fluidic communication in series between the distal handpiece end and the proximal handpiece end. The cut-off valve is configured to cut off the gas stream flowing through the handpiece. A manually-controlled operating element is mechanically coupled to the cut-off valve, where the operating element is configured to be controlled by a dentist or technician holding the handpiece.

Abstract: A method and a device for introducing a dental filling material with a synthetic resin base into a tooth cavity. The filling material has a viscosity which is lowered under the action of vibrations, such as when subjected to ultrasound. The device subjects the filling material to the action of vibrations as it is injected into the tooth cavity.
