Comparative Evaluation of Effect of TENS on Controlling Pain Associated with Orthodontic Separator Placement—A Clinical Study

Abstract

Aim: To assess and contrast the efficacy of transcutaneous electrical nerve stimulation (TENS) therapy and topical anesthetic gel in reducing the level of pain associated with the placement of orthodontic separators. Materials and Methods: A cohort of 40 individuals, aged between 16 and 20 years, who were in need of fixed orthodontic treatment, was chosen for the study. Elastomeric separators were positioned bilaterally adjacent to the first molars in all participants, who were subsequently separated into two distinct cohorts. Those in group I received topical anesthetic gel, while those in group II underwent TENS therapy. After the placement of separators, the assessment of pain was conducted using the Visual Analog Scale (VAS) at specific intervals: Immediately after placement, 6, 12, 24, and 48 hours. Result: TENS group showed a significantly lower VAS score compared to the local anesthetic gel group at immediate, 6 hours, and 12 hours. Conclusion: Following the placement of elastomeric separators, it was found that TENS was more successful at reducing pain.
