Abstract
A significant cause of relapse of orthodontically treated teeth is thought to be the gingival and transseptal fibers of the periodontium, which are stretched and twisted as the tooth is rotated. To relieve the rotated tooth from forces exerted by the stretched fibers, circumferential supracrestal fiberotomy (CSF) was introduced. In simple CSF using a scalpel blade, intergingival, transgingival, transseptal, and semicircular fibers are transected. CSF helps the tissue remodelling and decreases relapse of orthodontically treated teeth. Laser offers numerous advantages compared with surgery. Laser CSF is expected to prevent relapse of orthodontically treated teeth. This study was conducted to evaluate the effectiveness and periodontal side effects of laser CSF on orthodontically rotated tooth. The aims were to compare the: amount of relapse and sulcus depth.The study involves 10 patients between age group of 14- 30 years. Patients with extraction site closure were included with the teeth adjacent to the extracted tooth involved in the study. A split mouth design was made with the maxillary right side as control whereas laser CSF was performed only on the maxillary left side. Laser diode of 980nm wavelength will be used. Evaluation after CSF was done after 4 weeks.
