Dental soft tissue surgery by diode lasers in cw- mode often causes carbonization of the tissues with following necrosis and a delay of wound healing. In vitro studies have already shown, that superpulsed diode laser surgery has much less disadvantages for the tissues in histological approach. Purpose of this study is to investigate in vivo, if superpulsed mode of operation can realize an improvement for surgeon and patient in soft tissue surgery.
Materials and methods :
26 patients were treated by diode lasers in different modes of operation for soft tissue surgery. 12 patients were treated by superpulsed Elexxion Claros diode laser :
810nm; 10- 50 W peak ; 10- 20 μs pulse duration; 12000- 20.000 Hz; 400μm fiber and 14 patients were treated by Vision MDL-10 diode laser : 980nm; 2,5 W; cw- mode and also 400 μm fiber.
Clinical treatment was documented by photos and questionnaires for patients and surgeons. Questions concerned: carbonization, coagulation, cutting speed, pain, swelling, bleeding, need for drugs, functional reduction and fibrine layer on wounds- during treatment, directly after treatment, after 1 day, after 3 days and after 1 week.
Results
The clinical observations and the questionnaires showed in most cases significant differences between cw- mode and superpulsed diode laser treatment in surgery. There was less carbonization in the superpulsed group.
The cutting speed was higher and the cut itself more defined and deeper by using superpulsed mode.
Superpulsed laser treatment had a shorter healing time than cw- mode treatment; the fibrine layer was build faster and also the removal of it was faster.
There was often no swelling after superpulsed diode laser treatment; and if a
swelling occured it was smaller and quicker gone as in cw- mode treatment.
The duration of pain was shorter and the amount of pain smaller in the superpulsed group, therefore the patients in the superpulsed group needed less analgetic drugs.
There was less functional reduction in time and amount for the superpulsed group. Only coagulation ability was better in the cw- mode group.

Conclusion :
Clinical studies have shown that superpulsed diode laser surgery is superior to continuous wave done treatment. Carbonization and thermal damage of the tissues can be reduced to a minimum, therefore healing is faster as in cw- mode surgery. Generation of a soft tissue cut is faster and more precise. Patients have less pain; in amount and time period. The need of drugs is reduced. There are less functional restrictions and there is less swelling.
The advantages of superpulsed mode of operation for soft tissue diode laser surgery are evident. Continuous wave mode should no longer be implemented in diode laser surgery.
