Xerostomia is a subjective complaint of dry mouth, whereas hyposalivation is an objective decreased of salivary flow. Hyposalivation was reported in 28.8 % of haemodialysis (HD) patients (Bruzda-Zwiech, 2014).
Stimulation of the salivary glands can be induced mechanically (for example, by chewing gum or acupressure) or through medications (such as pilocarpine, cevimeline, angiotensin-converting-enzyme inhibitors and angiotensin-receptor blockers) or by electrostimulation as transcutnaeous electrical nerve stimulation (TENS) (Bossola and Tazza, 2012). Eighty HD patients (40 diabetics and 40 nondiabetics) will receive 20 minutes of TENS on skin over bilateral parotid gland, 3 times weekly for 3 weeks to investigate the hyposalivation response of diabetic and non diabetic HD patients to TENS.

RECRUITING3-week response of salivary flow rate
the patients will be ordered to spit saliva in a graduated test tube for 5 minutes after the last session (session number 9). To calculate salivary flow rate: saliva volume will be divided on duration of saliva spitting.
Time frame: immediately after the last session
immediate response of saliva flow
the patients will be ordered to spit saliva in a graduated test tube for 5 minutes immediately after the first session . To calculate salivary flow rate: saliva volume will be divided on duration of saliva spitting.
Time frame: immediately after the first session
