Patent number: 8992216Abstract: There is provided a method for detecting interproximal tooth defects such as caries by injecting light at one or more wavelengths into a tooth and detecting reflected/diffracted light or emitted fluorescence. The detected light intensity is characteristic of a healthy or diseased tooth in the interproximal area.Type: GrantFiled: August 29, 2006Date of Patent: March 31, 2015Assignee: Dentsply Canada Ltd.Inventor: Naim Karazivan

Patent number: 8814571Abstract: The present invention relates to a tooth coating applicator (10), typically in the form of a strip (11), and a method for applying a dental sealant to a surface of a tooth (T), and specifically to the interproximal surface (S) thereof. The applicator (10) is elongated and is adapted to be typically inserted into an interproximal space (I) defined between a pair of adjacent teeth (T, T?) and to be gradually slid against a dental surface of one of the teeth.Type: GrantFiled: April 17, 2009Date of Patent: August 26, 2014Assignee: Dentsply Canada Ltd.Inventor: Naim Karazivan

Patent number: 8721327Abstract: A dental tartar detection and removal device (10) comprises a powered tartar removal instrument (12) adapted to be displaced along a tooth (T), illumination means (14) for illuminating with an incident light a region on the examined or periodontal site, detection means (16) for collecting the light reflected there at, and an analysing system for providing a signal to an operator (OP) of the tartar removal instrument (12) or to the tartar removal instrument when measurements on the reflected light in one or more predetermined ranges of wavelengths fall within any first predetermined range of values that are characteristic of tartar, or when said measurements do not fall within any second predetermined range of values that are characteristic of artefacts other than tartar.Type: GrantFiled: April 20, 2011Date of Patent: May 13, 2014Assignee: Dentsply Canada Ltd.Inventors: Naim Karazivan, Emmanuel Montini, François Ayotte

Patent number: 8297971Abstract: A dental tartar detection system (10), especially for detection of subgingival tartar (S), comprises a probe (12) adapted to be displaced along a tooth (T) an illumination system (14) for illuminating with an incident light a region on the tooth (T), a detection system (16) for collecting the light reflected thereat, and an analysis system (34) for providing a signal to an operator of the probe (12) when measurements on the reflected light in one or more predetermined range of wavelengths fall within any predetermined range of values that are characteristic of tartar (S). Typically, the detection of tartar (S) is achieved on the basis of the possible colors that tartar (S) can have such that the aforementioned one or more predetermined range of values cover wavelengths associated with colors of tartar (S).Type: GrantFiled: December 29, 2010Date of Patent: October 30, 2012Assignee: Dentsply Canada Ltd.Inventors: Yves Berube-Lauziere, Naim Karazivan, Emmanuel Montini, Sophie Bernier, Marc Levesque, Yvan Mimeault, Michel Doucet

Publication number: 20100040993Abstract: A diagnostic tool for detection of dental pathology is provided that functions as a self-contained, handheld unit. The tool includes a light probe and a housing within which are located an optical source, an optical detector, an analysis processor and a power source. The components within the housing are integrated on a support which is removable from the housing. The housing is in multiple pieces which may be connected together during operation, and disconnected to allow removal of the support. This allows for sterilization of the housing and light probe without the electrical components of the device.Type: ApplicationFiled: June 22, 2007Publication date: February 18, 2010Applicant: DENTSPLY CANADA LTD.Inventors: Naim Karazivan, Sylvain Trottier, Claude Cyr, Stéphane Gagnon, Francis Haynes
