The effect of low level laser on tooth sensitivity after orthodontic resection

The effect of low level laser on tooth sensivity after orthodontic resection.

This study is a randomized clinical trial with a parallel design and a control group. This randomized study will be performed on 28 patients. For randomization, Random numbers will be generated online and participants are assigned to two intervention groups and one control group.

This study, which will be performed in the specialized dental clinic of Kermanshah University of Medical Sciences, is double-blind. In this double-blind study, researchers and patients are kept blind as to what type of treatment they will receive. Also, researchers and participants have no role in the process of randomization and assignment of intervention groups.At each point, the surface of the mucosa dries, and the laser probe, which is covered with disposable nylon foam, adheres vertically to the mucosa and presses until the mucosa surface is partially white.

Inclusion criteria: age between 18 to 22 years; Informed consent; People who needed orthodontics. Exclusion criteria: Dependence on psychotropic drugs; History of anticonvulsant and antidepressant use; Chronic systemic diseases such as liver, lung, heart and kidney diseases etc...; History of neuropathic disorders

The first intervention group will receive a 200-wavelength laser (at each buccal or lingual surface, two dots, one 5 mm from the gingival margin and one point near the apex, apply the laser probe for 4 seconds). The second intervention group will receive a laser with a wavelength of 300 (in each buccal or lingual surface, two points, one at a distance of 5 mm from the gingival margin and one point near the apex, the laser probe is applied for 4 seconds). The control group will not receive a laser.

Tooth sensitivity

Production of random numbers online in Kitset Website. Divided quadrants will be drawn on 28 sheets of paper (in the number of patients) and random numbers will be written on each quadrant. Then, each of the papers will be placed in an envelope. Each patient removes an envelope and based on that, the method of placement of elastic seperator will be done in each quadrant. The production of random numbers and allocation concealment will be done by an impartial observer.

Laser light with a wavelength of 940 nm is not visible to the human eye and no heat is generated. Therefore, both the patient and the operator were blind (on or off) when using the laser. The laser radiation will be performed by the dentist's assistant. The operator will not know which quadrant is treated with the laser on and which is treated with the laser off. However, complete blinding of the patient will not be possible, and only blinding for laser on or off will be possible.
