Abstract

During the last several years research activities have been conducted to study PDT availability in stomatology for pathogenic microflora suppression, which presence causes different kinds of oral cavity inflammatory disease. Studies indicate that PDT can be alternative to traditional antibiotic therapy. We carried out research in order to determine the optimal method of tooth irradiation to provide necessary therapeutic radiation dose for affected parodontium tissue in case of inflammatory disease. These data can be used for fiber-optic catheter positioning for further influence on oral cavity nidus of inflammation during PDT and PD. 20 teeth ex vivo were examined. Teeth were irradiated with diode laser (680 nm). In different teeth regions laser radiation intensity was measured by LESA-01-Biospec spectrometer. Optimal radiation method for PDT and PD was found.
