Paper Abstract

The aim of study was to evaluate the effect of low-level laser radiation on the healing process after human lower molar extraction. Frequencies of 5 Hz, 292 Hz and 9000 Hz were used in this experiment. Monitoring the secretory IgA and albumin levels in saliva and changes in bone density were used as a marker of biostimulatory effect. Bone density after extraction and six month after surgical treatment was examined using the dental digital radiography. Wound closure was followed by healing of bone structure in extraction site. Changes of secretory IgA, albumin levels and bone density were compared in groups of patients with laser treatment and control group without any laser therapy. Differences in levels of the saliva markers were found to be significant comparing irradiated and non-irradiated groups, as well as comparing groups irradiated by various modulatory frequencies. Density of alveolar bone was examined on five slices acquired from every digital radiography image. Histogram were evaluated wit a computer program for microscopic image analysis. Density differences were verified in area of the whole slice. There were no significant differences found between bone density in irradiated and non irradiated groups perhaps due to our used therapeutical diagram.
