EFFICIENCY OF LOW-INTENSITY LASER IRRADIATION IN THE MANAGEMENT OF PATIENTS WITH ORAL MUCOSAL DISEASES ASSOCIATED WITH RHEUMATOID ARTHRITIS BY RESULTS OF DOPPLER ULTRASOUND

Abstract

Aim: To evaluate the therapeutic effectiveness of low-intensity laser irradiation in the treatment of patients with oral mucosal diseases in association with rheumatoid arthritis, according to parameters of Doppler ultrasonography of blood flow of lingual arteries. Materials and Methods: An examination of 25 patients with geographic tongue and concomitant rheumatoid arthritis and 12 practically healthy persons of the control group was carried out. In the main group (13 patients) the complex treatment of glossitis was carried out with non-contact laser irradiation of the affected tongue areas. Patients in the comparison group (12 persons) underwent standard treatment. Treatment effectiveness of patients in both groups was determined by the parameters of Doppler blood flow study of lingual arteries. Results: In the main group of patients, after diode laser therapy, a significant decrease in linear blood flow parameters (Vmax by 19.7%, TAMAX by 19.6%), an identical increase in volume velocity (Q by 21%) and an improvement in vascular tone and peripheral resistance (Pourcelot index by 12.5%, Gosling index by 13.1%) were observed. At the same time, a slight increase in the linear and volume velocity characteristics of blood circulation in lingual arteries during treatment of patients in the comparison group was not statistically significant (p>0.05) and with a high degree of probability differed from the control group. Conclusions: The use of low-intensity laser irradiation in the management of patients with oral mucosal diseases associated with rheumatoid arthritis contributes to the normalization of hemodynamics and the functional state in the vascular bed of the tongue.
