A multifunction hand-held syringe for use in dental restorative procedures in conjunction with conventional instrument delivery systems. The multi-function syringe includes multiple reservoirs for containing viscous material (e.g., resin and etchant), conduits for delivering etchant, water, air, and resin to an affected area, wherein the syringe is capable of delivering etchant, water, air, and resin to an affected area on the tooth surface. The multi-function hand-held syringe is further characterized by a light emitting source capable of curing the resin extruded onto the affected area. The syringe also includes a detachable shank such that the nozzle may be removed for cleaning. The syringe also includes a coupling for connecting the syringe to conventional instrument delivery systems such that the syringe is portable.
