  • Publication number: 20190209437
    Abstract: Compositions and methods for whitening the teeth of a patient or subject are described for performing a dental prophylaxis or cleaning procedure during which at least one tooth whitening composition is applied to the surface of a stained tooth, said compositions and methods resulting in a tooth color change that is noticeable to the patient or subject immediately following the procedure. The novel procedure allows for a high degree of tooth whitening to be safely achieved in a short period of time while under the control of a dentist, dental hygienist, or other dental professional, and which at least partially coincides with the performance of a dental prophylaxis or cleaning procedure in order to save significant clinical operatory chair time compared to cleaning and whitening procedures that are performed in non-overlapping time frames or appointments. Light may also be used to enhance whitening.

  • Patent number: 9775790
    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.

  • Patent number: 9662284
    Abstract: Compositions and methods for whitening the teeth of a patient or subject include the application of at least one tooth whitening composition having a viscosity of at least 100 centipoise to the surface of a stained tooth, accompanied by the application of a sealant composition that forms protective film or coating on the tooth surface to resist moisture contamination of the oxidizing composition. The whitening procedure can be further enhanced by removal of acquired pellicle from the tooth surface prior to application of oxidizing and sealant compositions. The novel procedure allows for a high degree of tooth whitening by protecting the oxidizing composition while it is in contact with the tooth surface.

  • Patent number: 9320580
    Abstract: A hand-held, ergonomic instrument with an LED that emits actinic light in visible wavelengths mounts a replaceable applicator cup with a reservoir for a tooth whitening composition held in place against a user's tooth during a whitening procedure. Actinic light is directed onto the tooth surface through a window in the cup and the tooth whitening composition substantially without attenuation, delivering at least about 100 milliwatts per square centimeter of light energy to the tooth surface. The cup includes a rigid body for mounting the cup to the instrument and an opaque flexible sleeve molded in place over the outside of the body to form a seal with the tooth surface and prevent exposure of soft mouth surfaces to the actinic radiation during a whitening procedure. A safety switch disables the LED when the applicator cup is not in contact with a tooth surface.

  • Publication number: 20160106641
    Abstract: A thickened tooth whitening composition in gel form comprises hydrogen peroxide or a hydrogen peroxide precursor, and a thickening polymer or copolymer comprising a pendant sulfonic acid group moiety, preferably hydroxyethyl acrylate/sodium acryloyldimethyltaurate copolymer. Gels in accordance with the invention exhibit an extended shelf life without requiring refrigeration or other special storage conditions. A particularly efficacious manner of method of whitening teeth comprises applying a volume of a gel in accordance with the invention onto the bristles of a toothbrush, applying a volume of a toothpaste onto the toothbrush bristles, and brushing one or more teeth to be whitened with the toothbrush bristles onto which the toothpaste and the thickened tooth whitening composition were applied for a sufficient period to cause the composition and toothpaste to mix together.

  • Patent number: 8986005
    Abstract: An oral care device is described for contacting or transferring a dental composition to the hard or soft surfaces of the teeth comprising a backing layer and a discontinuous pattern of a dentally therapeutic composition. A method of using said oral care device to effectuate an aesthetic or therapeutic treatment is also described, whereby the oral care device is placed against the surface of at least one oral cavity structure, the discontinuous pattern of dentally therapeutic composition is contacted with or transferred to said structure. The backing layer may be left in place during the treatment period, or optionally removed from the oral cavity while leaving the therapeutic composition in contact with the target structure.

This not only ensures intimate contact of the teeth with the gel, 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 gel-coated teeth, after which a dental prophylaxis is performed by cleaning and scaling the teeth at the gum line, gingival margins, and crevicular spaces while avoiding excessive disruption of the sealant composition. This simultaneous cleaning and whitening procedure reduces patient time at the dentist compared to separate cleaning and whitening procedures.

  • Publication number: 20140011163
    Abstract: A vibratory fluid dispensing instrument holds a rheologically non-Newtonian (shear-thinning) liquid, gel, cream, or paste therapeutic composition in a container section of a disposable applying device from which the composition is manually dispensed into an applicator brush for application to one or more surfaces in an oral cavity. The instrument includes a vibratory appliance mounted to the device and mechanically coupled thereto to enable application of the composition in conjunction with mechanical energy that reduces the viscosity of the composition due to vibratory shear forces and thereby leads to better penetration of the composition into hard and soft tissue surfaces. The vibratory appliance can be separate from the applying device so that it can be removed from an applying device after the container section is empty and reused with a replacement applying device.
