Application of Diode Laser in Periodontal Treatment

Abstract

The diode laser frequently used in the field of dentistry has a wavelength of 810 nm. Its wavelength characteristic is not affected by water and it is absorbed by dark colored substances resulting in thermal effects. When human tissue is irradiated, theoretically the Diode Laser just penetrates the surface and reaches inside. However, in addition to that phenomenon, the tip itself emits high thermal energy due to continuous diffuse reflection. Therefore, when the fiber comes into contact with the tissue, the heat of the tip is first transmitted to the tissue before the laser is absorbed by the tissue and heat is generated, and incision and transpiration develop. The system is small, lightweight, power-saving, and is generally delivered by quartz fiber. It is frequently used for soft tissue incisions and is especially excellent for fine gingival contour modifications. With its low power output; healing promotion and pain relieving effects are achieved. In this article we discuss the current state and potential of Diode Laser use in periodontal disease management.
