<p>The invention relates to a dental instrument comprising a mirror and a suction device having an inlet. Liquid from the patient's oral cavity is sucked up through said inlet by said suction device. The reflecting surface of the mirror is passed through by an opening, which during use of the instrument forms the mouth of said inlet, the reflecting surface of the mirror thus being flushed clean by the liquid flowing across it.</p> |
