A dental probe for determining the vitality of a tooth, comprising a light emitter and a light receiver, wherein the light emitter emits light from an emitter surface adapted to be positioned on a hard dental surface of a tooth, wherein the light receiver collects light incident on a receiver surface adapted to be positioned on a hard dental surface of the tooth so that the optical path of the light emitted from the light emitter passes at least through a portion of the pulp chamber of the tooth. The light receiver includes a light shielding spacer member adjacent to the optical path for establishing and maintaining a distance of at least 50 μm between the gum line and the optical path at the receiver surface. The light emitter further a light shielding spacer member adjacent to the optical path for establishing and maintaining a distance between the gum line and the optical path at the emitter surface, wherein the light shielding spacer member establishes and maintains a distance of at least 50 μm between the gum line and the optical path at the emitter surface, and in that an apical-coronal diameter of the light emitter surface and the light receiver surface is at most 1200 μm in the direction normal to the optical path.

A system for monitoring anxiety of an individual includes a chair having at least a seat and a back, a base supporting the chair, and a first sensor disposed in at least one of the seat or the back. The first sensor is configured to, without being in direct contact with the individual, continuously obtain data related to a first physical characteristic from the individual seated in the chair. The first physical characteristic is one of respiration or pulse rate. The system further includes a display and a controller. The controller is configured to receive, in real-time, the data related to the first physical characteristic from the first sensor and compile a first metric from the received data. The first metric is configured to visually represent a change in the first physical characteristic. The controller is further configured to output the first metric to the display in real-time.

An oral irrigator includes a base having a pump mechanism, a reservoir housed within the base and fluidically connected with the pump mechanism. A handle with a jet tip is connected with an outlet from the pump mechanism to receive a pressurized fluid stream from the reservoir to direct a fluid at a surface inside an oral cavity. The oral irrigator also includes a radiant energy source and delivery system for directing radiant energy at a surface inside an oral cavity.

The present disclosure relates to a phototherapy device that can deliver light to tissues to activate photoactive agents that have been applied to the tissues or that are included within a fiber optic tip member of the device which may be coupled to a light source using a sleeve. The present disclosure also relates to methods of phototherapy using the phototherapy device such as anti-bactericidal treatment, anti-fungal treatment, anti-parasitic treatment, anti-viral treatment.

A dental syringe tip system for attachment to a dental syringe. The dental syringe tip system can include components such as an outer core, an inner core, and a carrier which can be combined in a multitude of combinations to achieve different fluid flow characteristics, such as discharge pressure and discharge pattern, through the dental syringe tip. The outer core and inner core can have passages designed to modify fluid flow characteristics. In addition, the outer core and inner core can have additional connectors for receiving fluids from sources other than a dental syringe. Some or all of the components can be separate to be assembled by a manufacturer or an end-user. Assembly of multiple components can be facilitated by retention features located on the components.

A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

An extra-oral capture hood includes a first cone that provides a first path for a vacuum product through the extra-oral capture hood. A second cone concentric with the first cone and disposed around the first cone provides a second path for the vacuum product through the extra-oral capture hood, the second path being located between the first cone and second cone. A disconnect is connected to at least one of the first cone or second cone, the disconnect being configured to connect the extra-oral capture hood to a duct, a valve or other component of a capture system.

Disclosed is a power generating system for a rotatory dental apparatus that can power the illumination source. The rotatory dental apparatus includes a supply hose having a hose connector at its one end. A swivel coupling connects the hose connector to the dental handpiece. The power generating system can be configured in the hose supply. In one case, the power generating system can be installed in the hose connector of the hose supply. In one case, the power generating system can be interposed between the two sections of the hose supply. In one case, the power generating system can be installed in a hose coupling that is interposed between the swivel coupling and the hose connector.

Provided herein are aptamers that bind specifically to the surface proteins of periodontal pathogens. Also provided herein are methods for detecting and treating periodontal disease in a subject. The method comprises detecting bacteria associated with periodontal disease by use of the present aptamers to analyze a sample taken from a gum pocket of a tooth of the subject; and treating the periodontal disease of the subject by administering to the gum pocket of the tooth a bactericide or an anti-microbial phototherapy to eradicate the bacteria associated with periodontal disease.

A method includes receiving scan data of a tooth during a first mode of operation, the scan data of the tooth having been generated by an intraoral scanner. The method includes invoking a second mode of operation and presenting, in a GUI, an image of the tooth. The method includes presenting, in the GUI, indications of a plurality of color zones of the tooth, the indications comprising, for at least one color zone of the plurality of color zones, an indication that insufficient color information has been received, wherein each color zone represents a separate region of the tooth for which an approximately uniform color is to be used. The method includes categorizing, for one or more color zones of the plurality of color zones for which sufficient color information has been received, each of the one or more color zones according to a color pallet used for dental prosthetics.
