Abstract: Disclosed is a method, and a system, for accomplishing the in situ formation of a gel in an interdental space. This is useful for the interdental application of one or more dental care agents, such as antimicrobial agents or other anti-plaque agents. The invention makes use of a two component system comprising a gelable liquid and a liquid gelling agent capable of bringing about gelation of the liquid. The system of the invention is arranged such that first the gelable, typically viscous, liquid can be applied, and then the liquid gelling agent is forced, e.g. jetted, into the applied gelable liquid. The system is designed such as to prevent the gelling agent and the gelable liquid to come into contact with each other before both have been applied. The system is configured to allow the gelable liquid to be applied prior to the gelling agent.

Abstract: Disclosed is a new method, and a system, for the delivery of particles comprising at least one oral care agent to the oral cavity, so as to particularly enable delivery into the interproximal spaces. The method involves providing a liquid comprising the particles and introducing the liquid into the oral cavity in the form of a fluid jet, said jet having a velocity of from 0.5 m/s to 5 m/s. The fluid jet can be generated by an appropriately adapted oral irrigator, but other devices can be used as well. The invention is particularly suitable for the delivery of adhesive gel particles comprising one or more oral care agents, preferably particles for the controlled and/or slow release of such agents.

Abstract: A delivery system includes a first layer which includes at least one of positively-charged particles and positively-charged molecules. A second layer is in contact with the first layer. The second layer includes at least one of negatively-charged particles and negatively-charged molecules. At least one of the first and second layers includes an active agent, such as an oral care agent. The active agent is incorporated in the positively-charged particles and/or negatively-charged particles of the respective layer.

Abstract: Disclosed is a preparation for the interdental delivery of oral care agent. The preparation comprising one or more oral care agents contained in particles comprising an orally acceptable release matrix, wherein the particles are resiliently deformable and capable of being compressed so as to fit in an interdental space. The particles can thus be provided in a size slightly larger than that of an interdental space. By compression they can be inserted, particularly jetted, into interdental spaces, and their tendency to thereupon expand again provides a force retaining them in the space where they were applied, without being prone to washing away by saliva.

Abstract: This is a preliminary amendment. The claims are amended for non-statutory reasons: to remove multiple dependencies, to correct one or more informalities, to remove figure label number(s), and/or to replace European-style claim phraseology with American-style claim language. The scope of the claims have not been changed and no new matter is added.The amendment to the claims does not address issues of patentability. Applicant(s) reserve(s) the right to continue prosecution of any subject matter canceled, or not claimed because of eliminating multiple dependencies, in this, a divisional, or other continuing application.Examination of the application is now respectfully requested. If any points remain in issue that may best be resolved through a personal or telephonic interview, the Examiner is respectfully requested to contact the undersigned at the telephone number listed below.

Abstract: Disclosed is a new method, and a system, for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The pH change typically is a pH increase in the event of a direct pH-triggered gelation. The pH change typically is a pH decrease in the event of gelation induced by ions, such as calcium ions, released from a pH-sensitive carrier. The device comprises a dispensing unit for the composition, a distal end of which is adapted to apply said substance onto teeth or gums. The device further comprises an electrode system comprising first and second electrodes, the first electrode being adapted to be held against the composition at a location at or near teeth or gums, and the second electrode being adapted to be held against the composition at a location away from teeth or gums, The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the electrodes.
