To date there is no information that evaluates, from the patient's point of view, the experience of undergoing CO(2) laser skin resurfacing. This article investigates the outcome of laser resurfacing for various cutaneous problems with respect to the patient's expectations and experiences and the surgeon's opinions. Patients were entered into the study(More)
The laser treatment of port-wine stains (PWS) has as a main aim the irreversible damage of ectatic vessels. Blood content of the subcutaneous venous plexus in PWS can be increased by a factor of seven or more, compared to that of the normal skin. The venous blood velocity ranges from 0.1-1 mm/s in capillaries to approximately 22 mm/s in larger vessels of(More)
OBJECTIVE To analyse microleakage in Class V cavity preparation with Er;Cr:YSGG at different parameters using a self-etching adhesive system. BACKGROUND Several studies reported microleakage around composite restorations when cavity preparation is done or treated by Er;Cr:YSGG laser. We want to compare different energy densities in order to obtain the(More)
Argon laser therapy of superficial pigmented lesions in both young and old people is associated with a risk of complications including delayed wound closure and hypo/hypertrophic scarring. Problems may also occur after treatment of lesions located on the eyelid. To minimize the risk of these problems coagulation of deep tissue should be avoided. We(More)
Modern CO2 systems can be programmed to emit high power density short pulses to produce instantaneous conversion of cutaneous tissue to a gaseous state. Tissue ablation occurs so quickly that there is minimal thermal conduction to the adjacent structures. The limits of thermal injury can be minimized to the order of only 50Μ thick and, in spite of the(More)
