In general, in the treatment process for treating teeth or periodontality of a dental patient, the patient should keep the mouth open while the treatment is being performed. By the way, regardless of age and sex, it is difficult to endure physically and open the jaw joints for a long time. Moreover, in the case of young children or the elderly, the strength of the jaw muscles is weak, so that they may shut themselves unknowingly during the treatment, which may lead to wrong treatment or even injury to the teeth or the oral cavity.

Thus, a mouse prop is used between the molars of the upper jaw and the lower teeth of the lower jaw to support the upper jaw and the lower jaw at the time of dental treatment so that the patient can keep the mouth open. That is, as shown in Figure 1, when the patient opens the mouth with the inclined support (1a, 1b) in the upper and lower portions respectively so as to match the angle of the molars of the upper jaw teeth and lower teeth A mouse prop (1) is used as the basic form. The mouse prop 1 is usually made of a soft silicone rubber or the like, and the support parts 1a and 1b which contact the molar teeth of the upper jaw teeth and the molar teeth of the lower jaw teeth, respectively, are disposed so that the mouse prop 1 is not separated between the teeth. The flange 1c is formed up and down, and the knurling processing for preventing the slip of the mouse prop 1 is performed.

On the other hand, when a doctor diagnoses or treats a tooth and periodontal region while the patient opens his mouth and wears a mouth prop, illumination of the inside of the oral cavity is necessary to clearly observe and treat the region. Thus, in the past, the illumination lamp installed in the doctor unit was used, but this has a problem in that it is difficult to light up to a deep part in the oral cavity because there is a limitation in adjusting the irradiation angle of the light source. Therefore, at present, this problem is solved by using a separate lighting device mainly composed of a small flash shape of a size similar to a handpiece, or by using a lighting device provided in the handpiece itself. By the way, in the case of using a small flash type lighting device, there is a problem that the dentist has to hold the lighting device by hand at all times, which interferes with the treatment of the patient.
