The system directs the focal point of laser radiation to an exact location by a focus sensor and maintains focus by a positioning clamp. The focus sensor, laser pad termination system and positioning clamp also provides for control of laser radiation pulse firing. The system further includes a cooling system for cooling the surface to be engaged by laser radiation with a nonaqueous solution. The cooling system applies pulses of nonaqueous solution synchronously in between pulses of laser radiation. The system also provides for performance of surgical procedures such as root canals, whereby infected areas of a tooth are accessed through a hole drilled in the gums and jaw bone. |
