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.
