THE USE OF STRUCTURAL CHANGES IN BONE TISSUE IN DENTAL PRACTICE AND THE POSSIBILITY OF THEIR USE IN THE EXAMINATION OF PATIENTS WITH CHRONIC KIDNEY DISEASE.

The subject of the study is the prospects of implementing the method of X-ray densitometry in preparation for dental implantation (DI) in patients with chronic kidney disease (CKD). The aim of the study was to determine the diagnostic significance of densitometry results (frequency and severity of BMD) in middle-aged patients with various stages of CKD and healthy controls when choosing a method of dental implantation. Methodology. We selected 203 ambulatory charts of middle-aged patients which underwent dual-energy X-ray absorptiometry (DXA) with DTX 200 densitometer (Denmark) on the basis of Saratov Regional Center of Osteoporosis Prevention and Treatment and osteoporosis centers. Results and discussion. The somatic pathology of the examined persons was represented by: diseases of cardiovascular system, kidney diseases, rheumatologic diseases, combination of cardiovascular diseases and kidney diseases and cardiovascular and rheumatologic diseases. Data on the periodontal status of those examined were unknown. Twelve groups of examinees were distinguished according to gender, glomerular filtration rate (GFR). Two other gender groups were patients on outpatient hemodialysis. BMD in CHD depends on patient's sex, somatic pathology and the nature of treatment, stage of the disease. As the disease severity increases, the number of patients with normal BMD decreases, the number of patients with low BMD increases, with osteopenia diagnosed in every third of both genders, and osteoporosis (OD) in every third man and every second woman. The pathology itself, regardless of the patient's gender, is of decisive importance in the development of a decreased BMD in patients with somatic pathology. It is important for MDI to distinguish forms of renal osteodystrophy (ROD), but X-ray densitometry cannot distinguish OP from several forms of ROD. Conclusions. In middle-aged individuals, X-ray densitometry should be performed as a mandatory examination for the timely detection of OP. For outpatient dental patients with CKD, we suggest not to test for MPCT by this method prior to MDI.
