Abstract
Medical lasers can be divided into two general groups: High powered lasers (e. g. CO2, argon, Nd-YAG etc.) which utilize the thermal effect for cutting or coagulation, and low-power lasers (e. g. diode, He-Ne etc.) which utilize photoactivation or photo-chemical reactions to relieve pain or promote wound healing. It is good indication of soft tissue tumours resection using high powered CO2, or Nd-YAG lasers. Various low-power output lasers are used frequently in the oral region. We have obtained good results by treating neurological ailments such as facial palsy and pain in the maxillofacial region by irradiating the stellate ganglion with 300mW output power of Nd: YAG laser and diode lasers.
