Laser dental is a type of laser specially designed for use in oral or dental surgery.
In the United States, the use of laser in the gums was first approved by the Food and Drug Administration in the early 1990s, and used on hard tissues such as mandibular or tooth mandibles obtained approval in 1996. Some dental laser variants are used with different wavelengths and this means they are better suited for different applications.

Soft-tissue lasers
- Laser diode
- Carbon dioxide laser Laser
- Nd: YAG
Laser diode wavelengths in the range 810-1.100 nm are poorly absorbed by soft tissues such as gingiva, and can not be used to cut or ablate the soft tissues. In contrast, the distal tip of the diode glass fiber is scorched (by burning ink or by burning wood, etc.) and the char is heated by a laser beam of 810-1,100 m, which in turn heats the glass fiber ends. The soft tissue is cut, on contact, by the tip of the hot scorched glass and not by the laser beam.
Similarly ND: YAG lasers are used for soft tissue surgery in the oral cavity, such as gingivectomy, periodontal periodulal debridement, LANAP, frenectomy, biopsy, and coagulation of transplant donor sites. Wavelength laser Nd: YAG partially absorbed by pigments in tissues such as hemoglobin and melanin. These lasers are often used for debridement and disinfection of periodontal pockets. Their coagulative ability to form fibrin allows them to seal the treated pouch.
The CO 2 laser remains the best surgical laser for soft tissue where cutting and hemostasis are achieved photo-thermal (radiant).

Soft and hard networking lasers
- Er: YAG laser
- Laser carbon dioxide
- Er, Cr: YSGG laser
Erbium laser has a hard and soft tissue. They can be used for a number of dental procedures, and allow more procedures to be performed without local anesthesia. Erbium lasers can be used for hard tissue procedures such as bone cutting and creating minimal thermal and mechanical trauma to adjacent tissues. This hardened tissue procedure shows an excellent healing response. Soft-tissue applications with erbium lasers have less hemostasis and coagulation capability than CO 2 lasers. The new CO 2 laser that operates at 9300 nm has a strong absorption power in soft and hard tissue and is the latest alternative to erbium lasers. The 9300 nm laser erodes hard tissue over 5,000 Â ° C, which often produces very bright thermal radiation.
Removal of dental caries
In September 2016 Cochrane's collaboration published a systematic review of current evidence comparing the use of lasers for caries removal, in both deciduous and adult teeth, with standard dental drills. Nine trials were reviewed, published between 1998 and 2014, totaling 662 participants. This includes three types of lasers: Er: YAG; Er, Cr: YSGG; and Nd: YAG. Overall the quality of available evidence is found to be low, and the authors can not recommend a caries removal method over another. There is no evidence of a difference between the marginal integrity or endurance of the restorations placed. However, there is some evidence that lasers produce less pain and require less anesthesia than drill. The authors conclude that more research is needed.
Laser costs
The use of dental lasers remains limited, with cost and effectiveness being a major obstacle. The cost of dental lasers ranges from $ 4,000 to $ 130,000, where the cost of a pneumatic gear drill is between $ 200 and $ 500. The hard tissue lasers are unable to perform some routine operations in perforated tooth care.
Benefits of laser
Dental lasers are not without its benefits, because laser use can reduce morbidity after surgery, and reduce the need for anesthesia. Because of tissue cauterization there will be less bleeding after soft-tissue procedures, and some of the risks of alternative electrical surgery procedures are avoided.
History
Kumar Patel made the first CO 2 laser in 1964, the same year Nd: YAG Laser was invented at Bell Labs.
