Patent number: 8641415Abstract: In a method and apparatus for detecting a crack in a human tooth, especially one covered by a restoration, such as a crown, the approach is to stress the suspect tooth and, by means of acoustic emission techniques, analyze the characteristics of the resultant acoustic emission from the tooth. To aid the identification of a crack from the acoustic emission signal, a baseline may be obtained by performing this procedure at a time when the tooth is known not be cracked, e.g., when a restoration is placed on it. This baseline acoustic emission signature is recorded. This procedure is repeated at intervals. The subsequent measurements are compared with the baseline to identify changes that indicate the initiation and growth of a crack. The invention includes apparatus for implementing the method. The approach is to integrate the acoustic emission pulser and sensor into commercially available dental instruments, e.g., a tooth polisher and a water syringe.Type: GrantFiled: January 3, 2011Date of Patent: February 4, 2014Assignee: Kallis Technical ServicesInventor: James M.

Patent number: 8403665Abstract: An oral irrigator has a pump, a discharge nozzle and a pressure control. The pump has a generally constant operating speed and feeds the discharge nozzle. The pressure control is adapted to modify a discharge pressure at the nozzle without a significant change in pump speed. The pressure control modifies a level of fluid flow restriction between the pump and the nozzle. The modification of the level of fluid flow restriction is accomplished by modifying aspects of a fluid flow path extending through the pressure control. The aspects modified include the diameter, length and/or number of direction changes of the fluid flow path.Type: GrantFiled: February 22, 2010Date of Patent: March 26, 2013Assignee: Water Pik, Inc.Inventors: Brenda Lee Thomas, Kurt Michael Taylor

Patent number: 8398324Abstract: Dispenser for dispensing a substance onto a substrate, such as a tooth treatment compound onto teeth, includes a vial including a pair of thin members forming a cavity therebetween in which the substance is arranged and a conduit defining an internal dispensing channel communicating with the cavity, an applicator tip arranged in connection with the conduit and including projections adapted to contact the substrate, and a cap including a cavity. The cap removably attaches to the vial and when attached, covers the applicator tip and seals the internal channel. When the cap is detached from the vial and the thin members are squeezed toward one another, the substance in the cavity is urged out of the cavity into and through the internal channel in the conduit and onto the projections to enable it to be brought into contact with the substrate.Type: GrantFiled: January 22, 2010Date of Patent: March 19, 2013Assignee: JBL Radical Innovations, LLCInventor: Jonathan B. Levine

Patent number: 8328553Abstract: A capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.Type: GrantFiled: March 9, 2007Date of Patent: December 11, 2012Assignee: 3M Innovative Properties CompanyInventors: Bruce R. Broyles, Marc Peuker, Sebastian Guggenmos, Andreas J. Boehm, Hubert Schloegl, Michael Knee, Werner Fichtl, John W. Dubbe, Arno Hohmann, Darin J. Meyertholen, Dean K. Reidt, Steven J. Maxa, Urs Mahnel

Publication number: 20120301843Abstract: Disclosed is a dental handpiece wherein the chip air line is selectively switched to the ON-state for using both water and chip air, and to the OFF-state for using only water. The dental handpiece has a switching valve provided between the circumferential chip air channel and the chip air line in the handpiece body for selectively allowing and preventing communication therebetween, wherein opening of the valve switches the communication to the ON-state in which chip air is allowed to pass from the circumferential chip air channel into the chip air line, whereas closing of the valve switches the communication to an OFF-state in which chip air is prevented from passing from the circumferential chip air channel into the chip air line.Type: ApplicationFiled: May 24, 2012Publication date: November 29, 2012Inventors: Takao Kimura, Masanori Mizunuma, Keita Yokochi
