Study aim
-
Determining the recurrence rate, patient's pain, pocket depth and gingival resorption after treatment of rotated teeth with fibrotomy with surgical razor alone, surgical razor and low power laser, diode laser alone, diode laser with low power laser and low power laser alone، one month later.
Comparison of recurrence rate, patient's pain and pocket depth after treatment of rotated teeth with 5 different ways
-
Design
-
Clinical trial with control group, with parallel groups (6 groups in total), one-side blinded, randomized, on 90 patients. Random allocation process is performed with random allocation software.
-
Settings and conduct
-
The place is in the office of orthodontists. The data recorder, researcher and statistician goes blind
-
Participants/Inclusion and exclusion criteria
-
Patients undergoing fixed orthodontic treatment who were 15 to 30 years old at the beginning of treatment and had rotated teeth and are now at the end of their fixed treatment should have a rotation rate of 20 to 70 degrees. No systemic disease, gingivitis and periodontitis, proximal and deep caries, developmental and anatomical malformations, use of drugs that disrupt bone metabolism, conditions in which the use of lasers is prohibited, such as pregnancy. Patients should have good oral hygiene and plaque index under 10%
