Abstract
A tooth brushing device with a video scope including a video scope having a prism mirror 10 and an objective lens 9 that form light from an object into an image, a CCD unit 8 that converts the light formed into the image, into an electric signal, and a handle section 7 held by an operator, a tooth brush having a brush section having a cavity portion 4 formed therein and a handle section held by the operator, and a display section for displaying an image picked up by the video scope, in which the handle section of the toothbrush is integrated with the handle section 7 and the prism mirror 10 is arranged where a clear image of a tooth to be brushed by the operator is picked up by the video scope. When images are picked up through the cavity portion 4 formed in the brush section and a toothbrush section and an image pickup section are independently installed in the handle section 7, images can be picked up even during a tooth brushing operation.
