Abstract
Many researchers reported successfully using low-power lasers such as the ruby, He-Ne, Nd: YAG, and Ga-Al-As, and other diode lasers to relieve pain and promote wound healing. However, the output power of He-Ne and diode lasers has not been completely satisfactory. Those laser are also referred to as non thermal, cold, or soft lasers because it is thought that their effect is electromagnetic rather than thermal. Recently diode lasers with greater output power have been developed, and we have had considerable success in the clinical application of laser irradiation with an approximate output of 300mW. For quite some time, we have obtained good results in the treatment of neurological disorders such as paresthesia in the lower lip and mental region after minor surgery or facial palsy by low power irradiation of the stellate ganglion with 300mW output of Nd: YAG, and other diode lasers. Also, the results in the treatment of temporomandibular joint disorder patients are satisfactory. This paper reports clinical usefulness and therapeutic results of low-power laser therapy in the treatment of oral and maxillofacial region.
