Evaluation of the Use of Photobiomodulation After the Installation of Elastometric Separators

Orthodontic Appliance Complication Clinical Trial

Official title:
Evaluation of the Use of Photobiomodulation After the Installation of Elastometric Separators - Randomized Controlled Clinical Trial.

Clinical Trial Summary

The greatest dropout rate of orthodontic treatments is pain, from the installation of the elastomeric separators, to the exchange of wires and accessories. This process that presents both physiological and psychological responses negatively affects patients' quality of life due to the difficulty of chewing and biting. The sample will be comprised of individuals who will receive elastomeric spacers on the mesial and distal surfaces of the upper first molars, randomized into two groups, the group being irradiated with the low intensity laser, called the experimental group, and the placebo group, simulated laser. In the installation of the tabs, the experimental group will receive a single application in the mesial and distal cervical portion and in the apical third of the molars. The energy delivered at each point will be 2J, per vestibular and lingual, 6 points, totaling 12 J of energy per tooth. To evaluate the perception of pain we will use the Visual Analogue Scale (EVA) after 1h, for all groups. The gingival pockets cytokines will be collected with an absorbent paper cone for 30 seconds on both groups and compared between them by ELISA. It is expected that patients in the irradiated group will have lower pain perception and less cytokines than in the placebo group.
