Abstract

A dental apparatus includes a light irradiation unit for emitting a light to irradiate an oral cavity, an image capturing unit for image-capturing the oral cavity light irradiated by the light irradiation unit, and an output unit for outputting data for highlighting and displaying at least one of a plaque site and a calculus site on an image of the oral cavity based on an image captured result by the image capturing unit.

First claim

What is claimed is:

1 . A dental apparatus, comprising:
a light source configured to irradiate an oral cavity with a light; at least one imager configured to image the oral cavity irradiated with the light; a position detector configured to detect a position of the dental apparatus; and an output unit configured to output image data detected by the at least one imager to display at least one of a plaque site and a calculus site based on the image data and the position.

2 . The dental apparatus according to claim 1 , wherein the position detector detects an angle of the dental apparatus, and the output unit outputs an angle data detected by the position detector.

3 . The dental apparatus according to claim 1 , wherein the position detector detects a spatial position of the dental apparatus.

4 . The dental apparatus according to claim 3 , wherein the position detector comprises a locator signal generator and a receiver corresponding to a reference position, the receiver receives a locator signal from the locator signal generator, and the position detector determines a spatial position data based on the locator signal and outputs the spatial position data.

5 . The dental apparatus according to claim 1 , wherein the light source further irradiates the oral cavity with an excitation light that induces a photodisinfection action.

6 . The dental apparatus according to claim 1 , further comprising;
a disinfection light source configured to irradiate the oral cavity with an excitation light that induces a photodisinfection action.

7 . The dental apparatus according to claim 1 , wherein the light source further irradiates the oral cavity with p-polarized light, and the image data is based on an s-polarized light amount returned from the oral cavity.

8 . The dental apparatus according to claim 7 , wherein the image data discerns between the plaque site and the calculus site based on a reflected light amount from the image data.

9 . The dental apparatus according to claim 1 , wherein the light source further irradiates the oral cavity with s-polarized light, and the image data is based on an p-polarized light amount returned from the oral cavity.

10 . The dental apparatus according to claim 7 , wherein the image data discerns between the plaque site and the calculus site based on a reflected light amount from the image data.

11 . A dental apparatus, comprising:
a light source that irradiates an oral cavity with a light; at least one imager that images the oral cavity irradiated with the light; a position detector that detects a position of the dental apparatus; and an output unit that outputs image data detected by the at least one imager to display at least one of a plaque site and a calculus site based on the image data and the position.

12 . A method, comprising:
irradiating an oral cavity with a light from a light source; imaging, by at least one imager, the oral cavity irradiated with the light; detecting, by a position detector, a position of the dental apparatus; and outputting, by an output unit, image data detected by the at least one imager to display at least one of a plaque site and a calculus site based on the image data and the position.

13 . The method according to claim 12 , wherein the position detector detects an angle of the dental apparatus, and the output unit outputs an angle data detected by the position detector.

14 . The method according to claim 12 , wherein the position detector detects a spatial position of the dental apparatus.

15 . The method according to claim 14 , wherein the position detector comprises a locator signal generator and a receiver corresponding to a reference position, the receiver receives a locator signal from the locator signal generator, and the position detector determines a spatial position data based on the locator signal and outputs the spatial position data.

16 . The method according to claim 12 , wherein the light source further irradiates the oral cavity with an excitation light that induces a photodisinfection action.

17 . The method according to claim 12 , further comprising;
a disinfection light source that irradiates the oral cavity with an excitation light that induces a photodisinfection action.

18 . The method according to claim 12 , wherein the light source further irradiates the oral cavity with p-polarized light, and the image data is based on an s-polarized light amount returned from the oral cavity.

19 . The method according to claim 18 , wherein the image data discerns between the plaque site and the calculus site based on a reflected light amount from the image data.

20 . The method according to claim 12 , wherein the light source further irradiates the oral cavity with s-polarized light, and the image data is based on an p-polarized light amount returned from the oral cavity.
