FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to dentistry, and can be used in diagnostics of internal disorders in temporomandibular joint. Time of occurrence of noise audio signals and phases of opening and closing a mouth arising during mutual displacement of the articular surfaces by means of electronic stethoscope are registered. Phonogram record is started in the “joint front view” mode, when after audio signal, a patient slowly opens and closes the mouth once for 15 seconds. At that, the first movement a patient always starts to the right, in case of noise audio signal occurence a doctor fixes the time and the phase of opening or closing the mouth using time intervals on the phonogram: up to 7.5 s - opening the mouth, from 7.5 to 15 seconds - closing the mouth; from 1 to 2.5 seconds - initial phase of opening the mouth, from 2.5 to 5 seconds - medium phase of opening the mouth, from 5 seconds to 7.5 s - final phase of opening the mouth; from 7.5 seconds to 10.0 seconds - initial phase of closing the mouth, from 10.0 seconds to 12.5 - medium phase of closing the mouth, from 12.5 to 15 seconds - final phase of closing the mouth. When detecting reciprocal click, in the form of high amplitude tooth on the phonogram within the initial phase of opening the mouth in the time interval from 1 to 2.5 seconds and the final phase of closing the mouth in the time interval from 12.5 to 15 seconds - diagnosis of front settable displacement of articular disk. When detecting reciprocal click, in the form of high amplitude tooth and crepitation in the initial phase of opening the mouth in the form of multiple repeating low amplitude teeth in the time interval from 1 to 2.5 seconds and the final phase of closing the mouth from 12.5 to 15 seconds - diagnosis of front settable displacement of articular disk and secondary osteoarthrosis.
EFFECT: method enables to diagnose internal disorders in temporomandibular joint at the early stages of disease, perform long-term record of audio signals for survey in dynamics of clinical course of pathological process in the TMJ, to assess the treatment efficacy, to document data of examination and treatment in a patient's medical history properly due to fixation of time at closing and opening the mouth when detecting reciprocal click, crepitation on the phonogram.
