An instrument that enables a dental professional to subject a surgical site simultaneously to (a) mechanical cutting, scraping and grinding, and (b) las er trimming and cauterization. As a result, simultaneous removal of diseased tissue and destruction of residual bacteria is enabled. The instrument comprises a hollow shank (20) having a rearward fitting (22) and a forward contact head (24). Within the shank extends a fiber optic bundle (26). As shown, laser energy (36) is delivered from a laser (28) through the fitting and the laser bundle to the contact head. In the contact head are a surgical blade (30) and an exit window (32) for the laser energy.
