When the sensor is located on the bristle set back plate, the determination is made on the basis of the position of the bristle set relative to the cheek of the user.

  • Publication number: 20150140515
    Abstract: A tooth whitening method applies a light transmitting oxidizing composition to teeth in an oral cavity, after which a hand-held LED light source with a light transmitting lens and a cup forming a chamber having an open end is moved over the teeth so that the cup distributes the oxidizing composition while the teeth are exposed to light transmitted through the lens. This not only ensures intimate contact of the teeth with the oxidizing composition, but also maintains a more or less constant spacing between the light source and the tooth surfaces for optimum results. A sealant is then applied to the teeth to resist moisture contamination of the oxidizing composition.

  • Publication number: 20150118636
    Abstract: A method for controlling a dental instrument includes a foot pedal responsive to commands from a user. An operating mode is selectable between normal and boost cycle. A conventional mode is selectable by pressing and holding the foot pedal to a first level to operate in normal mode. The foot pedal operates in a boost mode when the pedal advances to a second level. Maintained mode is selectable by tapping the foot pedal to change modes between idle, normal and boost mode. Each mode is switched by tapping the foot pedal. The pedal switches between the second process and the first process by pressing and holding the foot pedal at the desired level corresponding to normal or boost mode. The pedal switches from the first process to the second process by tapping the foot pedal at the level corresponding to normal or boost.

  • Publication number: 20150111169
    Abstract: Provided is a dental ultrasonic cleaning device that efficiently cleans teeth or dentures in an oral cavity using ultrasonic waves. A dental ultrasonic cleaning device 1 emits ultrasonic waves through a cleaning-liquid (W1) to the surface of a cleaning-target 26, ultrasonically cleaning it. An ultrasonic born 24 propagates ultrasonic waves being generated by an ultrasonic-wave transducer 23 and emits them from the vibratory surface 25 provided at the tip-end of the horn 24. A liquid-reserving part 27 is provided, surrounding the vibratory surface 25 of the ultrasonic horn 24, which temporarily reserves the cleaning-liquid (W1) between the vibratory surface 25 and the cleaning-target 26. A cap-member 33 is provided at a certain interval opposite the liquid-reserving part 27.

  • Patent number: 9011823
    Abstract: Mouth rinses, dentifrices, lozenges, confections, chewing gums, and similar delivery vehicles containing non-toxic soluble calcium are used prior to administration of a fluoride-containing composition to increase the effectiveness of the fluoride therapy. An effective amount of calcium is released into the oral cavity and allowed to penetrate into the oral tissue. Calcium-bound fluoride deposits form in the oral tissue upon subsequent administration of the fluoride-containing composition to provide increased salivary, plaque and oral tissue fluoride concentrations.

  • Patent number: 9005587
    Abstract: The present invention provides compositions including saturated calcium phosphate (sCaP) solutions, that may be prepared from mixtures of calcium deficient apatite and one or more of sodium fluoride and zinc chloride, or F or Zn ions. The solutions may be prepared from mixtures of calcium compounds and one or more of sodium or potassium phosphates, sodium or potassium fluoride and zinc salts with, for instance, either phosphoric or hydrochloric acids. Such compositions may be useful for increasing occlusion of dentin tubules, decreasing bacterial attachment to dentin tubules, decreasing bacterial growth or colonization on tooth surfaces such as enamel and dentin surfaces including on dentin tubules, increasing resistance to acid dissolution, inhibiting dental caries formation and progression and tooth decay and inhibiting development of tooth hypersensitivity.
