Gradation of the severity of myofascial pain syndrome of the masticatory muscles

Relevance. Due to the high prevalence of myofascial pain syndrome of the masticatory muscles, the issue of treatment of this pathology remains relevant. Due to the heterogeneity of the severity of clinical manifestations, these additional examination methods, the development of a treatment plan by a dentist causes certain difficulties.

Materials and methods. Based on the data of a clinical and functional examination of 102 people aged 18 to 35 years, a gradation of the severity of MBS of the masticatory muscles was developed. In a clinical study, the presence and severity of pain during palpation, the degree of mouth opening, and an assessment of functional activity on the MAS scale were determined. Ultrasound examination was used to study the indicators of the area and thickness of the cross-section of the chewing muscles, visualization and size of trigger points. According to the electromyographic study, a comparative analysis of the average amplitude of the masticatory muscle, the total biopotential, and an assessment of the symmetry of the masticatory muscles was carried out.

Results. The data obtained made it possible to develop a gradation of the severity of MBS by 3 degrees, depending on the indicators (mild, moderate, high).

Conclusion. The development of this graduation will allow for an individual patient-oriented approach to the treatment of this category of people, which will contribute to improving the quality of medical care at a dental appointment
