Abstract:
Chitosan nanoparticles are provided for use in the in vivo treatment of connective tissues in root canal therapies. The nanoparticles are optionally linked with one or more photoactivatable compounds for providing antibactenal/antibiofilm properties, neutralizing bacterial byproducts and/or chemical/photodynamic crosslinking to achieve enhanced mechanical properties, chemical stability in connective tissues and/or to improve surface/interfacial integrity between filling material and connective tissue.
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:
The present invention relates to methods for the restoration of a decayed portion of an anterior tooth or re-restoration of a previously filled anterior tooth, and to dental matrices and composite resin dispensers that may be used in the methods for the restoration of a decayed portion of an anterior tooth.
Abstract:
Devices and methods for dispensing material from a dental handpiece. In one example, the method includes receiving an input that indicates that an amount of the material is to be dispensed from the container of the dental handpiece. The method also includes rotating an electric motor to rotate an imbalanced mass to vibrate a vibration transmission element that vibrates the material in the container. The method also includes dispensing the amount of the material from the container with a piston based on the input.

Abstract:
An apparatus and method for heating an endodontic instrument by infrared radiation includes a housing defining a chamber. An infrared heating element is positioned within the chamber. The housing includes an aperture and an adjacent holder for holding the endodontic instrument, such as an obturator. The endodontic instrument held by the holder extends through the aperture and into the chamber. The infrared heating element directs infrared radiation toward the endodontic instrument, which heats the endodontic instrument.
Abstract:
A holder for a delivery device for delivering filler material into a prepared root canal comprises a body, a mounting portion adapted to removably receive the delivery device; and a heating circuit having a heating device wherein said heating device is positioned to be in thermal communication with said delivery device when the delivery device is mounted to the holder. The holder thus enables heating of the filling material in situ in the prepared root canal at the time of insertion of the filling material in to the canal and while the filler material is being packed into the prepared canal.
Abstract:
The present invention is directed to root canal obturation in a tooth. In one embodiment, a plug is positioned in a root canal and bonded to the root canal by applying a light-curing adhesive to the canal and exposing the plug to a light source to bond the plug to the root canal. In another embodiment, a carrier is disclosed having an optically transmissive plug portion for insertion into the canal. In still another embodiment, the plug portion of the carrier includes an optical fiber to transmit light from a light source into the plug portion. In still yet another embodiment, a filler material is heated and injected into the root canal in a semi-liquid state and exposed to light to cure the adhesive.
Abstract:
A dental obturation system, which is configured such that a power terminal unit is installed between a rotary unit and a cartridge unit such that a heating unit can heat a filling material and a needle member, mounted to the front end of a main body having a battery therein, can be rotated while applying the heated filling material to a root canal, so that an operator can easily and conveniently administer dental treatment without changing his/her posture or the orientation of the main body according to the location of a decayed tooth of a patient.
