Ezlase (Diode lasers) are being used to treat periodontal disease, apthous ulcers and herpetic lesions, and to desensitize teeth.
They are used at very low and safe power settings that allow us to remove diseased tissue while leaving healthy tissue alone, at the same time killing bacteria that cause disease and biostimulating the periodontal pocket.
Biostimulation at low power levels with a diode laser can increase circulation, collagen formation, and fibroblastic and osteoblastic activity. The laser actually allows us to kick-start the healing process at the bottom of the periodontal pocket -- a huge benefit over traditional therapies. The fact that the laser can remove diseased tissue, kill the bacteria that cause the disease, and stimulate healing, makes laser therapy a big advantage over traditional methods.
Until recently, soft-tissue dental diode lasers used one of two wavelengths: 810 nm or 980 nm. The older wavelengths, 810nm and 980nm were selected by laser manufacturers because of their commercial availability and energy absorption characteristics in soft tissue.
An analysis of the wavelength absorption chart (Figure 1) shows that the new 940 nm wavelength can provide great hemostasis during soft tissue procedures because of its position on the absorption peaks of Hb and HbO2 while being slightly off the absorption peak of H2O.
In addition, clinical use by experienced diode laser users are indicating that the new ComfortPulse™, pulse characteristics are more comfortable for patients. This research led BIOLASE Technology, to develop the ezlase, the first dental laser to obtain clearance at this unique 940 nm wavelength.
