| Summary: | Background: Both chronic kidney disease (CKD) and its treatment can affect a wide range of tissues and systems. It directly or indirectly affects flow, concentrations and composition of saliva. Hemodialysis can effectively minimize most of these complications to some extent. Aims: The main aim of this study was to know the salivary content of sodium, potassium, calcium, urea, bicarbonate and oral manifestations in patients with CKD. Subjects and Methods: For this study, 50 patients diagnosed with CKD and 50 systemically and periodontally healthy individuals were subjected to a detailed general and intraoral examination. Whole un-stimulated saliva samples of all the selected subjects were collected and subjected to calcium (Ca), phosphorous (P), sodium (Na), potassium (K), bicarbonate and urea analysis. Statistical Analysis Used: Paired t-test, Mann-Whitney test. Results: Among 50 study subjects, 26 subjects had reduced salivary flow in the range of 0.1-0.4 ml/min. Intraoral examination of the study subjects revealed pallor, increased deposition of calculus, bleeding gums, metallic taste, hypoplasia of teeth and fissured tongue. There was a significant difference between healthy and prehemodialysis patients in the salivary sodium, potassium, calcium, phosphorus, urea levels and the difference was insignificant in relation to bicarbonate levels. Conclusions: Alterations in salivary calcium, phosphorous, urea, sodium, potassium levels were significantly higher in the study groups when compared to control groups and the difference was insignificant in relation to bicarbonate level. The increased levels in dialysis patients correlated with renal disease severity.
