Abstract

Orthodontic treatment not only improves the malocclusion, but also brings beauty and confidence to patients. However, we can’t ignore the accompanying orthodontic pain that gives rise to the inconvenience to patients. Therefore, the effective method of relieving orthodontic pain has become a hot issue recently. The present study aimed to clinically evaluate whether Low-Level Laser Therapy (LLLT) via Nd:YAG laser could reduce pain caused by orthodontic treatment. One hundred and fifty orthodontic patients who had fixed orthodontic placements in the maxillary arch for the first time were recruited. They were averagely and randomly assigned to the LLLT group, placebo group, and control group. The Nd:YAG laser irradiation was exerted to the buccal and lingual sides of the maxillary teeth of LLLT group every day for the first week. The placebo group had the laser fiber positioned into the mouth at the same areas without laser irradiation. The control group had no laser intervention. All patients received the survey to describe their pain within the period. Also, the Gingival Crevicular Fluid (GCF) was collected to measure the contents of IL-1β, TNF-α and PGE2 by ELISA. The results showed that LLLT did not affect the start of pain perception or the most painful day. However, LLLT significantly ceased the pain sooner. Also, comparing with the placebo group and control group, the patients in the LLLT group had lower mean scores for pain on each day as well as intensity of pain on the most painful day. In addition, the IL-1β, TNF-α and PGE2 levels in GCF decreased significantly by LLLT. Moreover, the patients showed better satisfaction to the LLLT treatment. These results hint us that LLLT could efficiently alleviate the pain and shorten the pain span caused by orthodontic treatment. It also could improve the patients’ acceptance to orthodontic treatment.
