Abstract
Abstract An apparatus for the recordation of images indicating the location of dental restorations in the mouth of an individual comprises support and positioning means for the person whose dental features are to be recorded, a first source of ultraviolet light located and arranged to illuminate the mouth area of the patient, a second source of visible light located and arranged to illuminate at least the face area of the patient, and a camera located and positioned to take a photograph of at least the mouth area while at least the face area is illuminated by the light sources. The intensity of the light sources may be adjustable to provide an accurate rendering of flesh tones while accentuating the restorations.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
An apparatus for the recordation of images indicating the location of dental restorations in the mouth of an individual, comprising support and positioning means for the person whose dental features are to be recorded; a first source of ultraviolet light located and arranged to illuminate the mouth area of the patient; means for adjusting the light output of said ultraviolet light source; a second source of visible light located and arranged to illuminate at least the face area of the patient; means for adjusting the light output of said second visible light source; and camera means located and positioned to take a photograph of at least said mouth area while at least said face area is illuminated by said first and second light sources.
Claim 2
Independent Claim
124 words
An apparatus for the recordation of images indicating the location of dental restorations in the mouth of an individual, comprising support and positioning means for the person whose dental features are to be recorded; a first source of ultraviolet light located and arranged to illuminate the mouth area of the patient; means for adjusting the light output of said ultraviolet light source; a second source of visible light located and arranged to illuminate at least the face area of the patient; means for adjusting the light output of said second visible light source; and camera means located and positioned to take a photograph of at least said mouth area while at least said face area is illuminated by said first and second light sources.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1, wherein said first source of ultraviolet light comprises a pair of ultraviolet flash units spaced equidistant from the patient on opposite sides of the line between the camera and the patient.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2, wherein said second source of visible light includes a light box and a ring-flash unit.
Claim 5
Dependent Claim
22 words
The apparatus of claim 3, wherein said ring-flash, light box and ultraviolet flash units are synchronized to the exposure of the film.
Claim 6
Independent Claim
124 words
A method for producing an image of at least the mouth and face area of a patient whereby non-florescing dental reconstructions are highlighted and the remainder of the patient's face appearing in the picture appears in true color, comprising the steps of (i) positioning the patient before a camera; (ii) locating a first source of ultraviolet light to bathe the mouth area of the patient in such ultraviolet light; (iii) locating a second source of visible light such that at least the face portion of the patient is bathed in such visible light; and (iv) exposing a section of film such that the latent image carried thereon is as a result of both the effects of said visible and ultraviolet light upon the patient.
Claim 7
Independent Claim
124 words
A method for producing an image of at least the mouth and face area of a patient whereby non-florescing dental reconstructions are highlighted and the remainder of the patient's face appearing in the picture appears in true color, comprising the steps of (i) positioning the patient before a camera; (ii) locating a first source of ultraviolet light to bathe the mouth area of the patient in such ultraviolet light; (iii) locating a second source of visible light such that at least the face portion of the patient is bathed in such visible light; and (iv) exposing a section of film such that the latent image carried thereon is as a result of both the effects of said visible and ultraviolet light upon the patient.
