The aim of this study is to evaluate the effect of low level laser therapy (LLLT) on pain management in people commencing orthodontic treatment. The study design is a randomized controlled trial.
Participants' pain will be dealt with by laser irradiation in one side of the jaw randomly, and the other side will be treated by a placebo procedure. Pain assessment will be measured using Visual Analog Scales (VAS).
The hypothesis of this study is that laser irradiation decreases the amount of pain following the insertion of orthodontic separators.
Here we have two groups:
The first group will undergo one dose of irradiation which is going to be applied on one side of the mouth whereas the opposing side will serve as a control side (placebo).
The second group will undergo two doses of irradiation which is going to be applied on one side of the mouth whereas the opposing side will serve as a control side (placebo).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Laser Irradiation One Dose | Experimental | Laser irradiation will be applied in one dose for patients in this group, but only on one side of the jaw. The other side of the jaw will receive a placebo procedure (i.e. a red light beam will be emitted on the gingival tissues as if they are irradiated by a laser beam). |
|
| Laser Irradiation Two doses | Experimental | Laser irradiation will be applied in two doses for patients in this group, but only on one side of the jaw. The second dose will be given after 24 hour of the first one. The other side of the jaw will receive a placebo procedure (i.e. a red light beam will be emitted on the gingival tissues as if they are irradiated by a laser beam). |
