Can devices for the instrumental analysis of temporomandibular joints be used interchangeably?

Abstract

OBJECTIVE\nTo compare the results obtained in instrumental analysis of temporomandibular joints function using joint vibration analysis and computerized axiography in healthy young adults.\n\n\nMETHODS\nThe study involved 187 people aged 18-21\xa0years old. All the participants were subjected to a clinical examination and instrumental diagnostics that included joint vibration analysis and computerized axiography.\n\n\nRESULTS\nSignificant differences in the maximum range of condylar movement (p =\xa00.0001) were reported between the group of people with healthy joints (p =\xa00.001) and the remaining groups. There were significant statistical differences (p =\xa00.02) between the group of people with loose articular ligaments and subluxation of the joint in terms of the parameter describing the symmetry of the sagittal position of the condyle on the distance of 5 mm.\n\n\nDISCUSSION\nElectrovibratography and computerized axiography did not reveal the same abnormalities in the functioning of the masticatory system.
