[Experimental-morphological study of the effects of diode laser scalpel with different irradiation parameters (wave length 0.97 mm) on oral mucosa].
An experimental-morphologic study of the effects of diode laser scalpel with different irradiation parameters (wave length 0.97 mm) on oral mucosa of 12 rabbits showed that incisions on oral membrane of the tongue, cheek and palate made by diode laser scalpel in different modes of operation (diode laser scalpel LC-0.97-IRE-Polus: in continuous mode /4 W/; frequency modulated mode 2000 x 100 /5 W/; frequency modulated mode 1000 x 50 /6 W/) after 2 hours produced the effect of superficial tissues defects with consequent development in 1-2 days of necrotic changes, oedema and angiomatosis, as well as perifocal inflammatory and productive reactions in the defects walls. In the continuous mode /4 W/ and frequency modulated mode 2000 x 100 /5 W/ to 10th day of the experiment there was epithelization of mucous defects on thr tongue, cheek and palate. This effect was observed only on day 20 after the frequency modulated mode 1000 x 50 /6 W/. In the control (incisions by radio-wave scalpel) epithelization of oral mucous membrane defects was seen on day 5-10 that was comparable with laser scalpel effects. Thus optimal results (by criterion of oral mucous membrane incisions healing) were received in the continuous mode /4 W/ and frequency modulated mode 2000 x 100 /5 W/.
