[Oral cavity pathology by renal failure].

The analysis of the scientific literature devoted to organ and tissue changes of oral cavity at the chronic renal insufficiency (CRI)is made. The number of patients in an end-stage of CRI constantly increases and patients receiving renal replacement therapy including hemodialysis, peritoneal dialysis or renal transplantation will comprise an enlarging segment of the dental patient population. Owing to CRI and its treatment there is a set of changes of teeth and oral cavity fabrics which remain even in a end-stage. Renal replacement therapy can affect periodontal tissues including gingival hyperplasia in immune suppressed renal transplantation patients and increased levels of bacterial contamination, gingival inflammation, formation of calculus, and possible increased prevalence and severity of destructive periodontal diseases. Besides, the presence of undiagnosed periodontitis may have significant effects on the medical management of the patients in end-stage of CRI.
