An orthodontic remodeling device, wherein the bite plate is modified to have textured teeth and gum facing surfaces so as to provide cleaning, massaging or acupressure effect when in use.

A method of providing a dental mouthpiece comprises: an oral cavity shape acquisition step for acquiring the shape of the oral cavity; a design requirement specification step of receiving a selected range and an amount of a medicine as design requirements; and a design step for outputting design on the basis of the shape of the oral cavity and the range and amount of application of the medicine, design data of a dental mouthpiece that is provided with a space for the medicine and is able to retain the above-mentioned amount of the medicine in the application range.

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.

Disclosed is a toothpick for periodontal care for applying a drug in an oral cavity. The toothpick for periodontal care according to the present invention includes: a drug container which accommodates a drug for periodontal care; and a toothpick part which is provided at one end portion of the drug container and has a nozzle hole that is formed in a longitudinal direction and communicates with an internal space of the drug container so as to apply the drug for periodontal care between a user's teeth.

The invention features a pharmaceutical suspension containing drug particles, a drug delivery device anchored in the mouth for continuously administering the pharmaceutical suspension, and methods of their use.

A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.

The present disclosure relates to bite plates for use with various orthodontic remodeling devices. A bite plate that releases fluoride during use, thus encouraging remineralization on enamel is described. Additionally, bite plates with a colorant or color-changing matrix that serve as indicators for fluoride concentration are also described.

Methods and systems for delivering drug particles to a target site are disclosed. An example method for implementing the subject matter described herein includes applying a drug delivery patch to a target site. The drug delivery patch can include a substrate, an electrode integrated with the substrate, and a fluid in the substrate having drug particles suspended in the fluid. The method further includes transmitting a signal to the drug delivery patch to power the drug delivery patch by inductive coupling. Powering the drug delivery patch causes the electrode in the drug delivery patch to motivate the drug particles towards a target site of the drug delivery patch.

This invention provides a non-surgical method for treating periodontitis comprising administering an article into a periodontal pocket, where the article comprises crosslinked collagen and hydroxyapatite. This invention also provides articles to be used within these methods.

In some embodiments, an apparatus comprises a housing, an emitter, and an electronic circuit. The housing is configured to fit within a patient's mouth. The emitter is at least partially encased within the housing. The emitter is configured to emit an effective amount of light to the alveolar soft tissue when the housing is disposed within the mouth. The electronic circuit is operatively coupled to the emitter. The electronic circuit is configured to control the emitter when the housing is disposed within the mouth and the apparatus is in use during orthodontic treatment. The apparatus and its use for regulating tooth movement or maintaining or improving oral tissue health are disclosed herein.
