Patent number: 10646315Abstract: A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode portion of the curing light. The device body includes a proximal gripping end and a distal head end. The device body is formed from a thermally conductive body material. Excellent heat conduction away from the LED dies is achieved using a thermally conductive layer disposed over the device body. The thermally conductive layer serves as a conduit to quickly conduct heat away from the LED dies for dissipation within the material of the device body In this manner, the material of the device body serves as a highly efficient heat dissipater. The surface area coupling the thermally conductive layer to the device body is sufficiently large that a majority (e g, substantially all) of heat being conducted by the thermally conductive layer is transferred to the device body during operation of the device.Type: GrantFiled: December 29, 2009Date of Patent: May 12, 2020Assignee: ULTRADENT PRODUCTS, INC.Inventors: Dee Jessop, Jared Sheetz, Neil Jessop

Patent number: 9539073Abstract: A dental curing light system is configured to include a dental curing light (100) having a device body (102) with a proximal handle portion (106) and a distal head portion (104). One or more light sources (120) for generating light are disposed on or within the device body (102). Generated light is emitted from the distal head portion (104) and includes wavelengths greater than about 420 nm and wavelengths less than 420 nm. A separate head attachment member or device (160) is coupleable over the distal head (110) of the device body (102) so as to receive substantially all light emitted from the distal head portion (104) of the device body (102).Type: GrantFiled: March 9, 2012Date of Patent: January 10, 2017Assignee: Ultradent Products, Inc.Inventor: Neil Jessop

Patent number: 8454558Abstract: A hollow inner plunger for use within a syringe-in-syringe mixing system for mixing a two-part dental composition. The hollow inner plunger includes a body having a continuous cylindrical wall defining an internal chamber for containing a first component. The body includes a proximal end and a distal end. A sealing plug and rupturable membrane are disposed at the distal end of the body, and the sealing plug and rupturable membrane are integrally formed together as a single piece (e.g., formed of a single piece of elastomeric material). An associated syringe-in-syringe mixing system includes a first plunger, the hollow inner plunger, and a syringe barrel configured to contain a second component. When assembled, the first plunger is slidably disposed within the hollow inner plunger, and the hollow inner plunger is slidably disposed within the syringe barrel. The two components are initially separated by the rupturable membrane.Type: GrantFiled: April 26, 2007Date of Patent: June 4, 2013Assignee: Ultradent Products, Inc.Inventors: Neil Jessop, Bruce S.

Patent number: 7833015Abstract: Kits and methods facilitate chair-side coating of an endodontic cone for improved sealing between the hydrophilic root canal tissue, the hydrophobic elastomer substrate of the endodontic cone, and a hydrophilic sealing resin. The kit includes one or more endodontic cones (e.g., formed of gutta percha) and a micro-dose container containing an adhesive composition. The practitioner can dip the cones into the adhesive composition so as to coat the cones chair-side, just prior to use. The adhesive composition includes an adhesive resin compound comprising at least one hydrophobic region and at least one hydrophilic region. The hydrophobic region is compatible with the hydrophobic elastomer substrate of the endodontic cone, while the hydrophilic region is compatible with a hydrophilic endodontic sealing resin.Type: GrantFiled: March 26, 2007Date of Patent: November 16, 2010Assignee: Ultradent Products, Inc.Inventors: Richard Tuttle, Jeff Wagner, Neil Jessop, Jaleena Fischer-Jessop
