The effectiveness of low-level laser therapy and low-intensity pulsed ultrasound in reducing pain induced by orthodontic separation: a randomized controlled trial.

Background: The low-level laser therapy (LLLT) and low-intensity pulsed ultrasound (LIPUS) have been recently applied to control pain during orthodontic treatment.

Objective: To evaluate and compare the effectiveness of LLLT and LIPUS in reducing pain induced by orthodontic separation.

Study Design: A single-blinded randomized controlled trial.

The effectiveness of interventions in reducing pain related to orthodontic separation: a systematic review and meta-analysis.

Background: Pain is an unpleasant experience and annoying sensation. To control this pain during orthodontic separation, different pharmacological and non-pharmacological methods have been used.

Objective: This systematic review and meta-analysis aimed to critically assess the evidence of the effectiveness of pharmacological and non-pharmacological methods in reducing pain induced by orthodontic separation.
