A trans-illuminative intraoral diagnostic lighting system includes a housing containing at least one LED and has a removable light diffusing positioning apparatus attached to it that facilitates proper positioning of the housing within the oral cavity of a person behind their teeth. When the LED(s) is/are activated, the oral cavity is illuminated and light passes through the teeth making their internal structures visible outside the oral cavity. A retractor may be used to retract the cheeks and lips to allow full exposure of the teeth and a camera may be employed to photograph the teeth from outside the oral cavity.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

A computer program and computer-based system for remotely assessing oral health of a person by obtaining at least one digital image (1) of the person's oral cavity and additional non-image data (2) comprising anamnestic information about the person (30). The digital images (1) are segmented using statistical image segmentation algorithms (101,102) to extract visible segments (3), which are further processed to predict any invisible segments (6). The resulting segments are processed by a statistical object detection algorithm (104) using the non-image data (2) as further input to identify dental features (7), which are filtered to select only risk-related dental features (8) using a risk database (9) and mapped to respective tooth regions (11) or oral cavity regions (12) in an Oral Risk Atlas (10).

An endoscope nosepiece includes a nosepiece body and a drape. The nosepiece body has a pipe line through which an insertion part is inserted. The drape is provided integrally with the nosepiece body and covers a head of a patient. The nosepiece body is integrally provided with a stopper portion. The drape is located on a side of the pipe line facing an outside of a body of the patient with respect to the stopper portion.

Methods and apparatuses for generating and displaying a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth). These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth.

An oral imaging device includes a base, a camera module, and a plurality of light source modules. The base includes a camera component, an opening surface, and a plurality of light source components connected to two sides of the camera component. A slant angle exists between each light source component and the camera component. The slant angle is a non-right angle. The opening surface is substantially parallel to the camera component. The camera module is located on the camera component and faces the opening surface. The plurality of light source modules each are located on each light source component and configured to project a light beam onto the opening surface. A center ray of the light beam passes through a center point of the opening surface.
