NCT07687810

Brief Summary

The goal of this clinical trial is to learn if Transcutaneous Electric Nerve Stimulation (TENS) device works to reduce discomfort during orthodontic treatment, by using orthodontic separators to mimic the discomfort of braces. The main questions it aims to answer are:

  • Does TENS device lower the participants level of discomfort?
  • Will TENS device be effective with orthodontic tooth movement? Researchers will place the separators on different sides of upper and lower first molars. TENS device will be applied on each participant on one of both teeth (according to their group), so that the results can be compared within the same person. Participants will:
  • Visit the clinic after 12 or 24 hours (depends on their group)
  • Stay on dental chair while TENS device is applied.
  • Rate the discomfort level on VAS scale before and after TENS device application.

Outcome Measures

Primary Outcomes (1)

  • Visual Analogue Scale

    To rate the level of discomfort pre and post TENS device application, where 0 is equivalent to no discomfort and 10 indicates most discomfort possible (the more reduction of the level of discomfort the better for the study results).

    From orthodontic separators application to 12 or 24 hours depends on the participant group.

Model Details: This study used a simple random sampling method. Each participant will have orthodontic separators applied medial and distal to contralateral first molars. Then each participant will have TENS device applied to one of the contralateral first molars (according to their group), making the other first molar of each participant to act as their own control.
