Publication number: 20120251981Abstract: The disclosure relates to a method for treating or preventing periodontal disease, such as gingivitis or periodontitis. The method may comprise the steps of a) providing a composition disposed within a reservoir, the reservoir being fluidly connected to an exterior surface of an applicator having a frictional stress value sufficient to cause mechanical displacement of a biofilm present on a surface of the tooth, or comprising pores having a diameter of 0.1-1000 ?m, or both, b) dispensing the composition through the applicator onto the exterior surface of the applicator, and c) applying the composition to an oral cavity surface.Type: ApplicationFiled: April 2, 2012Publication date: October 4, 2012Applicant: KLOX Technologies Inc.Inventors: Remigio Piergallini, Nikolaos Loupis, Shipra Rastogi

Patent number: 8263048Abstract: The invention is directed to a calcium phosphate complex and the composition containing the same for oral care applications, in which the calcium phosphate complex is formed by chelating the ?-polyglutamic acid (?-PGA) with amorphous calcium phosphate (ACP). This complex can prevent crystallization of ACP and maintain its high solubility. The calcium phosphate complex has superior mucoadhesion properties, allowing it to remain in the mouth longer and offering effective buffering, by which dental caries can be alleviated and prevented.Type: GrantFiled: December 21, 2010Date of Patent: September 11, 2012Assignee: Taipei Medical UniversityInventors: Jen-Chang Yang, Sheng-Yang Lee, Der-Zen Liu, Nai-Chia Teng, En-Sheng Ke, Chien Chung Chen, Dian-Yu Ji, Chen-Feng Ma, Hong-Da Wu

Publication number: 20120202167Abstract: Device and method for lasering biological tissue. In a general aspect, the device for lasering a biological tissue may include a source configured to provide a pulsed laser beam, an outcoupler configured to couple the laser beam towards the tissue, and an outfeeder configured to feed a photosensitizer in a direction of the tissue where the outfeeder is connected to the outcoupler. In another general aspect, a method for lasering a biological tissue may include applying a photosensitizer towards the tissue, providing a pulsed laser beam, and lasering a site of the tissue with the pulsed laser beam where the laser beam is emitted with a temporal width at a half maximum range from about 1 ps to about 100 ps.Type: ApplicationFiled: April 23, 2012Publication date: August 9, 2012Applicants: LUMERA LASER GMBHInventor: Anton KASENBACHER
