| Popis: | The ever increasing number of the patients presenting with postoperative wound infections and abscess is attributed by the majority of the authors to the significant changes in microflora, the impairment of therapeutic effectiveness of broad-spectrum antibiotics, and the reduction of the immune responsiveness. The present study has demonstrated that the microorganisms present in the mouth cavity show high in vitro sensitivity to laser radiation in the violet range of the spectrum. Specifically, irradiation at a distance of 3 cm from the treated surface and the time of exposure 5 minutes (at the power density 70 mW/cm2) produced a well apparent bacteriostatic effect whereas irradiation of a surface positioned 1 cm from the emitting source at the power density of 150 mW/cm2 caused complete eradication of the microorganisms. |
