title: Salivary flow and composition in diabetic and non-diabetic subjects.
abstract: The study investigated the effects of type 2 diabetes mellitus on salivary flow and composition in humans compared to healthy sex and age matched controls. Forty adult human subjects divided into 20 diabetic and 20 non-diabetic healthy subjects were included. Saliva samples were collected and analysed for glucose, total protein, calcium, sodium, potassium, chloride and bicarbonate. Salivary flow rate was also determined. The results showed that salivary glucose and potassium levels were significantly higher (p = 0.01 and 0.002 respectively) in diabetic patients compared with non-diabetic participants. It was also found that the diabetic patients had significant reduction in salivary flow rate when compared with non-diabetic individuals. In contrast, there was no significant difference in levels of total protein, Na+, Ca++, Cl- and HCO3- between the two groups. These results suggest that some oral diseases associated with diabetes mellitus may be due to altered levels of salivary glucose, potassium and flow.
