Efficacy of Transcutaneous Electric Nerve Stimulation (TENS) Therapy on Salivary Flow Rate

Abstract

Saliva is a complex and critical fluid; its important role is to maintain the Homeostasis of oral cavity. Hyposalivation refers to a decrease in salivary flow rate which is common sequelae in patients undergoing irradiation of malignant tumors of the head and neck and also uses of medications such as antihistamines, anticonvulsants, anti-hypertensives, diuretics, sedatives, and anxiolytics, etc. Transcutaneous electrical nerve stimulation (TENS) is a well-known therapy, used to treat pain and can increase the flow rate of saliva. The study aimed to evaluate the implications of TENS therapy and its repercussions on salivary flow rate. The study resulted in increased salivary flow in majority of the cases considered in the study.
