Influence of infrared radiation and high-frequency ultrasound on masticatory muscle tone in children

Abstract

The aim of the study was to study the effectiveness of the method proposed by the authors to normalize the tone of the masticatory muscles using infrared irradiation in combination with ultrasound exposure.
 Materials and methods. On the basis of the Institute of Dentistry. E.V. Borovsky at the Department of Pediatric, Preventive Dentistry and Orthodontics and at the Department of Therapeutic Dentistry, 15 children aged 9—12 years were examined and treated, including 7 boys and 8 girls. All patients were diagnosed with a distal bite, and there were also violations of the masticatory muscle tone. The study explores a technique that affects the change in the tone of the masticatory muscles using infrared radiation in combination with high-frequency ultrasound, consisting of 10 procedures.
 Results. As a result of the use of 10 procedures for observing resonance with high-frequency ultrasound in 15 children aged 9—12 years with distal bite and hypertonicity of the masticatory muscles, according to electromyography, there was a normalization of the assessment of the tone of the temporal muscles to the masticatory muscles proper from 1:0.7 to 0 .9:1.
 It is concluded that the proposed physiotherapeutic method makes it possible to normalize the function of the masticatory muscles by creating an equal tone between the masticatory and temporal muscles proper. Thus, the harmonious development of the maxillofacial region becomes possible and the effectiveness of orthodontic treatment increases with an already developed malocclusion pathology.
