Clinical Study of Tongue Coating in Patients with Chronic Kidney Disease Undergoing Chronic Dialysis Treatment

he study assessed the extent of tongue coating in 70 patients with end-stage chronic kidney disease (CKD) undergoing chronic dialysis treatment. The objective findings were gathered using criteria for the extent of tongue coating and by means of FitScan Breath Checker. The Kendall tau-b correlation coefficient revealed a strong, positive and statistically significant correlation between the extent of tongue coating and the age group. Another close correlation was observed between the extent of tongue-coating and the degree of halitosis. The criteria for determining the extent of tongue coating are particularly suited to the study of bedridden patients and CKD patients.
