A dental mirror comprising a shaft (2) and a head (3) having a mirror (4) arranged in a brace (6). The shaft has a boring (26), connected to a source of underpressure. The boring opens centrally below the mirror under a hole (13) in the brace. The brace is provided with shoulders (8) for holding the mirror and forming slits around the periphery of the mirror for connecting the boring with the space outside the mirror for suction of air, liquid and smaller particles through said slits to the boring and further to the source of underpressure. Said flow of air/liquid prevents formation of moisture and removes air/liquid-bubbles on the mirror. |
