# Ultra-Low Frequency TENS as an Adjunctive Therapy for Pain Management in Non-Surgical Periodontal Treatment: A Pilot Study

## TL;DR

This pilot study shows that using ultra-low frequency TENS during periodontal treatment significantly reduces pain and discomfort for patients.

## Contribution

The study introduces ULF-TENS as a novel, non-invasive method to improve patient comfort during non-surgical periodontal treatment.

## Key findings

- ULF-TENS significantly reduced pain during periodontal treatment (p < 0.0001).
- Patient discomfort was also significantly reduced with ULF-TENS (p < 0.0001).
- Maximum mouth opening increased after using ULF-TENS (p = 0.00062).

## Abstract

Introduction: non-surgical periodontal treatment, primarily comprising scaling and root planing, is crucial for the maintenance and enhancement of oral health. However, the invasive nature of this procedure often leads to patient discomfort and pain, which may deter individuals from seeking necessary dental care, ultimately compromising their oral health outcomes. Methods: This prospective randomized crossover split-mouth study involved the application of Ultra-Low Frequency (ULF) Transcutaneous Electrical Nerve Stimulation (TENS) in 20 adult patients undergoing non-surgical periodontal treatment. Pain and discomfort levels were quantitatively assessed during procedures conducted with and without the ULF-TENS intervention. Results: The assessment of maximum voluntary opening, pain intensity, and overall comfort levels indicated a statistically significant reduction in pain (p < 0.0001) and discomfort (p < 0.0001) when ULF-TENS was employed during the treatment, and an increase in the maximum mouth opening after TENS (p = 0.00062). Conclusions: The findings of this pilot study suggest that ULF-TENS may serve as a valuable adjunctive therapy in non-surgical periodontal treatment by reducing pain and discomfort, potentially enhancing patient comfort and compliance. Further research with larger sample sizes is warranted to confirm these findings.
