Dr.: Light microscopical, scanning electronmicroscopical and electron microscopical comparing examination of the effect of interventions created in the mouth cavity by means of the surgical scalpel the electrokauter and the C02-laser ray. Tissue effect interventions by means of surgical scalpel, elecrtokauter and C02-laser ray in the mouth cavity of 20 white rats has been examined. According to their light microscopical examinations both the laser and the electrokauter caused thermal injuries taking place in typical zones while by the scalpel the cut surface in rendered ragged. The band-width of the thermoinjury caused by the kauter is a multiple of that caused by the laser. It has been proved by means of scanning eleotronmicroscopial examinations that interventions by means of laser result in sharp wound borders, the wounds cut by means of kauter are characterised by the presence of a great number of carbonized specks while by means of the scalpel a mechanical tear of the tissues is brought about. By means of electronmicroscopical examination the characteristics of the typical thermoinjured zones are descibed. It has been established that in the case of laser the injury of the ultra-structure extends to 400 pm while in case of electrokauter it reaches a width of 1500 pm. The excellent haemostatic effect brought about by the thermoeffect by means of the laser, in contrast to the broad thermoinjured zone caused by the kauter, is obtained at a very mild thermoinjury.
