In the last six years AlGaAs-Diodelasers have become more and more popular. Due to their small size, their good electro-optical coupling and delicate glass fibers this type of laser fits into most dental offices. The first diode lasers and still most of the devices still on the market work in a continuos wave mode or in a gated mode up to 50 Hz. Using this setting high temperatures in the tissue are inevitable. In this randomized study we tried to evaluate the difference in clinical cutting efficiency, post operative outcome and the histological findings of the excisional biopsies using a new diode laser Ora-laser Jet 20.
