Aims and Objectives: To determine the effectiveness of transcutaneous electrical nerve stimulation (TENS) in stimulating salivary flow in post-radiated oral cancer patients, and to compare the salivary flow rate between unstimulated saliva and saliva stimulated with TENS in post-radiated oral cancer patients. Materials and Methods: In 30 patients who underwent radiotherapy for oral cancer, unstimulated saliva was collected every minute for 5 min in a graduated test tube. The TENS unit was activated and stimulated saliva was collected for 5 min in a separate graduated test tube, and the flow rate was compared with the unstimulated salivary flow rate. Results: A statistically significant improvement was seen in saliva production during stimulation (P < 0.001). In addition, statistically significant increase in TENS stimulated saliva was observed in patients aged ≥50 years compared to that in patients aged <50 years (P < 0.05). There was no significant difference in salivary flow rate between the two genders in both stimulated and unstimulated conditions, however, statistically significant increase in salivary flow rate was observed in males under stimulated condition (P < 0.01). Conclusion: TENS was highly effective in stimulating the whole salivary flow rate in post-radiated oral cancer patients. It is an effective supportive treatment modality in xerostomia patients caused by radiotherapy in oral cancer patients.
