Abstract
In an apparatus for directing a laser beam to a dental treatment area, where the apparatus includes a hand piece having an optical subsystem including a turning mirror for directing a laser beam to a treatment area via an orifice of the hand piece, a fluid supply subsystem creates a fluid flow within the hand piece proximate the turning mirror so as to mitigate contamination thereof.
