A dental laser is a type of laser designed specifically for use in oral surgery or dentistry. In the United States, the use of lasers on the gums was first approved by the Food and Drug Administration in the early 1990s, and use on hard tissue like teeth or the bone of the mandible gained approval in 1996. Several variants of dental lasers are in use with different wavelengths and these mean they are better suited for different applications. ==Soft tissue lasers== *diode lasers *carbon dioxide lasers,〔(CO2 Laser: Evidence based applications in dentistry )〕 *Nd:YAG laser Diode lasers in the 810–900 nm range are well absorbed by red colored tissues such as the gingivae increasingly being used in place of electrosurgery and standard surgery for soft tissue applications such as tissue contouring and gingivectomy. ND:YAG lasers are used for soft tissue surgeries in the oral cavity, such as gingivectomy, periodontal sulcular debridement, LANAP, frenectomy, biopsy, and coagulation of graft donor sites. The Nd:YAG laser wavelength is absorbed by pigment in the tissue. These lasers are often used for debridement and disinfection of periodontal pockets. Their ability to form fibrin allows them to seal treated pockets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dental laser」の詳細全文を読む スポンサード リンク
