Laser therapy

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 FDA 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.

A-Soft tissue lasers
-Diode lasers
-Carbon dioxide lasers
-Nd: YAG laser

B-Hard and Soft Tissue lasers

-Er: YAG laser
-Er. cr: YSGG laser

– Diode laser wavelengths in the 810-1.100mm range are poorly absorbed by soft tissues such as gingiva, and cannot be used for soft tissue cutting or ablation.
The distal end of the diode’s glass fiber is charred (by burned ink or by burned corkwood, etc.) and the char is heated by the 810-1.100mm laser beam, which in turn heats up the glass fiber tip. The soft tissue is cut, on contact by the hot charred glass tip and not by the laser beam.

– 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 partially absorbed by pigments in the tissue 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 treated pockets.

– The Co2 laser remains the best surgical laser for soft tissue where both cutting and hemostasis are achieved photo-thermally.

– Erbium lasers are both hard and soft tissue capable. They can be used for a host of dental procedures, and allow for more procedures to be done without local anesthesia. Erbium lasers can be used for hard tissue procedures like bone cutting and create minimal thermal and mechanical trauma to adjacent tissues. These hard tissue procedures show an excellent healing response. Soft tissue applications with erbium lasers feature less hemostasis and coagulation abilities relative to the Co2 lasers.
– Er, cr: YSGG laser was found to be effective in gum depigmentation.

However, the Laser diode gained more popularity due to its versatility, less interaction with hard tissue, ease of use, and the less expensive setup.

The addition of diode laser treatment to scaling and root planning (SRP) will produce significantly improved results. After (SRP), the diode laser is used on the soft tissue side of the periodontal pocket to remove the inflamed soft tissue and reduce the pathogens. This improvement in gingival health remains more stable than with conventional SRP treatment alone and tends to last longer.

Effects of lasers

-Inflammation reduction
-Accelerated tissue repair and cell growth
-Improved blood flow
-Reduced formation of scar tissue
-Pain relief

Laser therapy blocks the pain signals transmitted from injured parts of the body to the brain.
Increases the production and release of endorphins and enkephalins.

Advantages of laser

-Relatively bloodless surgical and post-surgical course
-The ability to coagulate, vaporize, or cut tissue
-Sterilization of wound tissue
-Minimal swelling and scaring
-No requirement for sutures
-Little mechanical trauma
-Reduce surgical time
-Decrease post-surgical pain
-High patient acceptance

With conventional mechanical instruments, complete access and disinfection may not be achieved during the treatment of periodontal pockets. Lasers have the potential advantages of bactericidal effect, detoxification effect, and removal of the epithelium lining and granulation tissue, which are desirable properties for the treatment of periodontal pockets. Thus, laser systems, applying the ablation effect of light energy which is completely different from conventional mechanical debridement, may emerge as a new technical modality for periodontal therapy in the near future.

We are pleased to announce that we have recently completed intensive training in laser periodontal therapy at RWTH Aachen University and now offer this treatment using the world’s best digital dental laser.

The laser effects make it possible for us to effectively treat gum disease problems and establish ideal conditions for healing the gums around teeth that have periodontal pockets.
Also, lasers can be for hyperplasia removal as well as in the treatment of peri-implantitis. The laser, due to its bactericidal and decontamination effect, can be used in the maintenance of implants. It has a high bactericidal effect without harmful effects around implants.
Laser now gives us a gentle and effective way to stop the damage being done by the infections in the gums. Patients who have had this form of laser treatment report that they have little or no discomfort after the procedure.

We are proud to be among the first of the growing number of dental offices in the country to provide this breakthrough laser treatment to our patients.
