OBJECTIVES: A study of the dental, periodontal, oral mucosal and salivary c
ondition of adult patients with chronic renal failure (CRF) receiving hemod
ialysis (HD).
MATERIAL AND METHODS: A total of 105 patients on HD were studied, together
with 53 healthy age and sex-matched controls. Indices employed included car
ious, absent and obturated teeth index (CAO index), plaque index, calculus
index and loss of periodontal attachment. Whole and parotid salivary secret
ions were also measured.
RESULTS: The CAO index was not significantly higher among HD patients than
controls (14.9 +/- 8.7 vs 13.3 +/- 7.9, respectively; t = 1.1; P = 0.3). Ho
wever, plaque and calculus indices were significantly higher in HD patients
(2.1 +/- 0.8 and 2.3 +/- 0.6, respectively) than controls (1.3 +/- 0.8 and
1.6 +/- 0.9) (P < 0.001). Loss of periodontal attachment was similar in bo
th groups (4.9 +/- 2.5 vs 4.2 +/- 2.5 in the HD patients and controls, resp
ectively) (t = 1.8; P = 0.07). There was no more oral mucosal pathology in
HD patients than in controls (chi-square = 5.8; P = 0.3). Stimulated saliva
ry secretion was significantly higher in controls than HD patients for both
whole (t = -5.2; P < 0.001) and parotid (t = -2.6; P = 0.01) salivas.
CONCLUSIONS: The results show significantly higher plaque and calculus indi
ces and lower salivary secretion among the HD patients than in healthy cont
rols.
