Comparison of salivary nitric oxide and epidermal growth factor level between diabetic patients and healthy individuals

The purpose of the current study was to compare salivary Nitric oxide and epidermal growth factor level in diabetic patients and healthy individuals. In this paired-control study 20 patients with type 1 diabetes mellitus, 20 patients with type 2 diabetes mellitus and 20 age and sex matched healthy subjects participated. The level of salivary Nitric oxide was increased in type 1 and 2 diabetic patients in comparison to control individuals (P = 0.037 and P = 0.058), respectively. Epidermal growth factor concentration was higher in type 1 and 2 diabetic patients compare to healthy ones, (P = 0.037 and P = 0.005) respectively. There was no significant difference between salivary Nitric oxide and Epidermal growth factor level regarding to the type of diabetes (P > 0.05). Significant statistical correlation was found between Nitric oxide and Epidermal growth factor levels and the fasting blood glucose and HbA1c (P < 0.001). Conclusions: Salivary Nitric oxide and Epidermal growth factor levels were higher in type 1 and type 2 diabetic patients and there was correlation with severity of disease.
