[On the role of psychological disorders in the development of the syndrome of pain dysfunction of the temporomandibular joint]. / O roli psikhologicheskikh faktorov v razvitii sindroma bolevoi disfunktsii visochno-nizhnechelyustnogo sustava.

There are significant disagreements related to the understanding of the etiopathogenesis of the syndrome of pain dysfunction of the temporomandibular joint. This review article examines the role of patient's psychological status as a significant factor influencing the occurrence and complications of this pathology, as evidenced by an increase in stress, anxiety, and depression in patients with the dysfunction. The need for a multidisciplinary and individual approach to the diagnosis and treatment is also discussed, which can significantly alleviate the severity of the disease, reduce complications, and shorten the rehabilitation time.

[Patient myofunctional adaptation to orthodontic treatment]. / Miofunktsional'naya adaptatsiya patsientov na ortodonticheskom prieme.

BACKGROUND: Myofunctional condition of the temporomandibular joint (TMJ) in everyday orthodontic practice is an important diagnostic criterion for evaluating the quality of orthodontic treatment. Pre-orthodontic preparation is often a necessary stage of orthodontic treatment. OBJECTIVE: To evaluate and compare the adaptation of the masticatory muscles of patients during pre-orthodontic preparation based on interference electromyography of the masticatory and temporal muscles with the data of patients after orthodontic treatment without preparation and with the indicators in the control group. MATERIALS AND METHODS: Electromyography indicators of the masticatory and temporal muscles of 82 patients aged 18 to 35 were obtained. Patients were divided into 3groups: 1st - with signs of TMJ dysfunction at the stage of pre-orthodontic preparation and orthodontic treatment; 2nd - patients after orthodontic treatment, having dissatisfaction with the state of the dentition; 3rd - a control group was compared composed of patients without signs of myofunctional dysfunction. RESULTS: Patients who have complaints after orthodontic treatment have different electromyography of the masticatory and temporal muscles in comparison with the control group. In patients with signs of TMJ dysfunction at the stage of preorthodontic preparation, after using a device of their own design, the structures of the temporomandibular joint were adapted to a new functional position. CONCLUSION: After using the device of its own design, myofunctional adaptation to a new functional position was obtained, which is confirmed by electromyographic studies.

[The survey of orthodontists on modern diagnosis and treatment planning of malocclusions in adults]. / Analiz dannykh oprosa vrachei-ortodontov o primenenii sovremennykh metodov diagnostiki i planirovaniia lecheniia zubocheliustnykh anomalii u vzroslykh.

PURPOSE: To examine the main factors affecting the quality of orthodontic treatment. MATERIAL AND METHODS: the survey was conducted over 3 years in 158 orthodontists who participated advanced training in the Departments of Therapeutic Dentistry, Pediatric Dentistry and Orthodontics. A questionnaire was drawn up for the survey including 4 sets of questions: diagnosis, treatment planning, completion and retention, documentation. The results obtained suggest that doctors who were interviewed conducted a complex of diagnostic measures 49.37%, an aesthetic index was never used in the diagnosis in 91.14% of respondents; diagnostic analysis of control and diagnostic models is not carried out by 72.78%, 15.19% use cone-beam computed tomography. In the course of treatment 50.63% conduct individualization of orthodontic equipment, 63.29% perform detailed bends. The rate of orthodontic retreatment in high as 63.92% of orthodontists has the corresponding experience. Completing the treatment process only 13.29% of orthodontist perform a complete analysis of occlusal contacts. Storage of medical records is possible for up to 3 years in 31.01%, up to 5 years in 34.81% of respondents, but 78.48% reported problems with storage space in clinics. CONCLUSION: There are issues that require clarification in the course of continuous education which are: rendering of a computerized X-ray examination; clinical review of cases causing difficulties; identifying and determining the causes of recurrent orthodontic treatment.
