Abstract: The purpose of the present invention is to provide a specific wound healing accelerator effective for accelerating healing of wounds, particularly of wounds in the oral cavity, or a composition which includes the wound healing accelerator. This wound healing accelerator including a specific polyphenol is easy to handle and is capable of accelerating would healing even by contact for a short time.

Abstract: It is intended to provide a sterilizer, an oral cavity sterilizer, a sterilization method, a sterilization apparatus, and a sterilizer evaluation method capable of enhancing a sterilization effect. The sterilizer including hydrogen peroxide and a catalase activity inhibitor containing scutellaria or green tea is brought into contact with a sterilization target. Next, the sterilization target is irradiated with light having a wavelength of 350 nm to 500 nm using a light emitting device formed of a semiconductor laser. By the light irradiation, the hydrogen peroxide is photolyzed to generate hydroxy radicals, and sterilization is achieved by the thus-generated hydroxy radicals.

Abstract: A dental treatment device in which attenuation of a laser beam is not liable to occur is provided.
