OBJECTIVES: According to a number of publications frequency of complaints on temporomandibular joints (TMJ) ranges from 27 to 76% and is on a third place in modern dentistry after other dental diseases such as caries and its complications and periodontal pathology. The necessity of high-quality, relevant and available for patient diagnosis is increasing.  To evaluate and compare the costs for diagnosis of patients with possible TMD from the payer’s perspective in the reform period of health care system and   implementation of health insurance in Ukraine.  METHODS: For the diagnosis of TMJ violations such alternative methods may be used: orthopantomography (OPG), zonography (ZG), ultrasonography (USG), 3D computed tomography (3D CT) and magnetic resonance imaging (MRI). From December 2013 to June 2015 122 patients with suspected TMD at Prosthetic Dentistry Department Danylo Halytsky Lviv National Medical University were examined.  RESULTS: The above mentioned methods singly and in combination were used for diagnosis. The costs of examination according to the average data in private and public clinics in Lviv are: OPG - 5-7 €; ZG - 5-7€, USG - 7-9 €, 3D CT - 18-30 €, MRI - 30-50 €. Resulting 62 OPG, 22 ZG, 54 USG, 20 3D CT and 2 MRI were conducted. Consequently, OPG, ZG and USG are available for most patients, less available is 3D CT. MRI is the most limited method.  CONCLUSIONS: Such diagnostic methods as OPG, ZG and USG are the most available for patients. They are informative, have no excessive radiation exposure and allow them to re-apply if the forward observation is necessary. In some cases the 3D CT method should be combined with USG, so that complex has a higher cost. MRI is the "gold" standard for diagnosis, but the high cost and features of study may limit its usage.
