摘要： An endodontic irrigator tip (20) having a cannula (60) with an annealed distal portion (65) and a proximal portion (63) enables the cannula (60) to easily move within a root canal. The cannula (60) extends from a hub (22) that is adapted for coupling with a syringe or other delivery device. The cannula (60) has an outlet orifice for delivering an irrigant out of the endodontic irrigator tip and into the root canal. The outlet orifice may be defined by a rounded rim that optimally enables the distal insertion end of the cannula to be advanced within the root canal.

摘要： The invention relates to a mechanised dental instrument consisting of an active part (2) and a sleeve (3) arranged on the end opposing said active part, said sleeve (3) being provided with a rotating drive means (4) that can directly engage, in the assembly position, in the head of a handpiece, with a rotating drive means located upstream of the head of the handpiece. The invention is characterised in that the drive means (4) is produced from a flat metallic piece which is fixed, especially by being slid over the axle (2a) of the active part (2), and is provided with at least one opening (5) that is shaped in such a way as to enable the circulation of the plastic material forming the sleeve (3) during the moulding over said axle (2a) and to thus ensure the connection of the rotating drive means on the axle (2a).

摘要： Methods and apparatus providing a critical set of endodontic instruments. The set includes a first endodontic instrument, a second endodontic instrument, and a third endodontic instrument. Each endodontic instrument includes a working portion that has a cone-like shape. Each working portion having an effective contact area defined by the exposed surface area of the working portion's respective cone-like shape. The difference between the effective contact areas of the first endodontic instrument and second endodontic instrument being substantially the same as the difference between the effective contact areas of the second endodontic instrument and third endodontic instrument.

摘要： An endodontic instrument for use in performing root canal therapy on a tooth having at least one straight flute which prevents self-threading or screwing of the instrument into a root canal during use. The instrument includes a shaft having a longitudinal central axis, a shank portion and an elongated working portion extending from the shank portion along the central axis, the elongated working portion having a proximal end, a distal end, and at least one peripheral surface and at least one straight flute formed on at least a portion of the peripheral surface of the working portion, the straight flute forming at least one cutting edge on the peripheral surface. The straight flute may be formed of a plurality of flute sections disposed on the peripheral surface of the instrument, the plurality of flute sections angularly displaced about the central axis with respect to one another. A method of manufacturing an endodontic instrument is also disclosed.

摘要： The invention is a new root canal reamer for use in a handpiece, with two or more cutting blades and an increasing and constant taper angle, whose reaming section comes between 16 and 30 mm in length. Said reaming section is designed to operate not only on the apical portion of the root canal, but also - entirely or partially - on the coronal portion. This new root canal reamer can have variable taper angle and tip diameter, thus making it possible to obtain a complete kit.

摘要： An integral, one-piece silanated particle impregnated gutta percha core/cone technique employs a thin layer of a luting agent, such as glass ionomer cement with a machined gutta percha core/cone (10), precisely matches the preparation, thereby reducing leakage and achieving a hermetic seal. The hermetic seal is further enhanced by a mono-block bond that occurs between the silanated particles in the gutta percha and the appropriate chemical sealant. Optional cryogenic treatment of the gutta percha material changes its molecular weight, making it stiffer and conducive to forming an integral, one piece core/cone, without the need for a separate carrier core to install the tapered gutta percha core/cone (10) within the root canal. Additionally, the tapered body of the core/cone may be reticulated in a slightly three dimensional texturized framework (20) to increase surface area and therefore increase retention. Optional line demarcation indicia (14a) are also placed on the core/cone. Additionally, the head (12) of the core/cone can be gripped by a delivery vehicle clasp.
