Effect of laser modulatory frequency on the secretory IgA and albumin levels after the extraction of human molars in the lower jaw

The subject of this work follows changes of the sIgA and albumin levels in the saliva of the patients treated after the extraction of their lower molars with either diode or He-Ne biostimulatory laser, using different modulatory frequencies. The results were compared with the sIgA and albumin levels in the saliva of the control, i.e. not- treated group. Appropriately chosen laser beam modulatory frequency should influence the increase in the sIgA and albumin levels against the base level. In our study, this hypothesis was confirmed in the group treated with the frequency of 9000Hz. The changes of the levels of the watched markers versus the control group were however statistically insignificant. The aim of this study was to contribute to the evaluation of specific modulatory frequencies for therapeutical use in a given pathological cause of the oral cavity.
