OBJECTIVES: To compare the effectiveness of transcutaneous electrical nerve stimulation (TENS) and microcurrent electrical nerve stimulation (MENS) on masticatory muscles pain bruxism patient. MATERIALS AND METHODS: A total of 60 subjects with the clinical diagnosis of bruxism were randomly allocated to two study groups. Group A received TENS (50 Hz, pulse width 0.5 msec, intensity 0 to 60 mA for 20 minutes for a period of seven days) and group B received MENS (0.5 Hz, intensity 1,000 muA for 20 minutes for a period of seven days). The outcome measures were assessed in term of visual analog scale (VAS) and digital pressometer of 2 Kg. RESULTS: The study showed significant change in intensity of pain as per VAS score (p <= 0.0001) and tenderness as per digital pressometer (p <= 0.0001). CONCLUSION: MENS could be used as an effective pain-relieving adjunct to TENS in the treatment of masticatory muscle pain due to bruxism.
