<p>The instrument has a smaller suction cannula with a frame (12) and a suction tip (13) with reduced dimension. An optical fiber (14) is integrated to the cannula and runs parallel to the cannula to provide a supplement light at the level of the suction tip. An optical connector (15) connects the optical fiber to another optical fiber connected to a power supply located on a dentist`s chair.
