Telishevska O. Reasoning for clinical diagnostic criteria for differential diagnosis temporomandibular disorders and diseases that mimic them

In the clinical part of work defined structure forms TMD, distribution disorders conducted by age and sex. Were analysed the components of the symptoms of the pathological process in temporomandibular disorders, defined the frequency and taxonomy of diseases or conditions that mimic temporomandibular disorders, defined stepwise relationship between temporomandibular disorders and symptoms that accompany them. Found that of 135 patients with suspected TMD in 97 patients (71.9%) confirmed various forms of TMD. Among them, in 80 patients (59.3%) identified arthrogenic pathology in 38 (28.1%) myogenic, in 17 (12.6%) TMJ hypermobility both singly and in combination. In 38 patients (28.1%) identified pathology that mimicked temporomandibular disorders. Defined leading complaints in the primary examination of the patient. As criteria for arthrogenic TMD can be used: pain in temporomandibular joints or articular murmurs and degree and trajectory mouth opening; for myogenic TMD: articular murmurs, changing trajectory mouth opening, accentuated palpation of masticatory muscles; for TMJ hypermobility: hypermobility of other joints, articular murmurs, changing trajectory mouth opening and accentuated palpation of the masticatory muscles. Among patients with diagnosed mimicked TMD detected 20 pathologies, symptoms of which imitated complaints like TMD. They are: 9 (45.0%) somatic genesis and 11 (55.0%) dental genesis. The analysis of the use of additional tests to determine the TMD (Hamburg index test and Helkimo index) found that more informative is index Helkimo but it ignores the noises in the TMJ that defined criteria for the diagnosis of all three forms of the TMD. Hamburg conclusion even though less informative but considers all indicators that are criteria. It information is more likely. In the analytical part of the work the computer program of differential diagnosis temporomandibular disorders was developed. It calculates an individual risk of various forms of temporomandibular disorders developing based on anamnesis and clinical signs identified in the patient.
