Renal failure is the reduced filtering function of the kidney as a result of damage to the function of many nephrons. Depending on the decrease in kidney functions, substances such as urea and creatine accumulate in the serum, thus the fluid-electrolyte balance in the body is disturbed. Kidney diseases give many radiographic and oral findings in the jaws, early diagnosis of these findings is very valuable in terms of patient health. Knowing that oral findings are distinctive in kidney patients, healthy oral environment should be created by eliminating the foci of infection that may be serious in the future by detecting the oral health condition early. In this manner, it is extremely important to evaluate the effects of chronic renal failure, to examine the oral and radiographic findings, to determine the treatment needs and to refer these patients to the necessary treatment immediately.
