Abstract

Despite the use of lasers in dentistry from the 1980s until today, the use of low level laser therapy laser (laser bio-stimulation) is
not very common in periodontology. Th e aim of this study is to evaluate the eff ect of low power 980 nm diode laser therapy aft er
gingivectomy and in comparison to the non-surgical periodontal treatment on bone healing. Twenty systemically healthy patients
with gingival hyperplasia due to chronic infl ammation in the maxilla or mandibular anterior region at least in 6 teeth symmetrically
were included. Bleeding on probing, gingival index, plaque index, clinical attachment levels were recorded at the beginning and 1
month aft er treatment. Th e patients were underwent scaling and root planning treatment aft er one week of periodontal diagnosis.
Th e curvatures of the gingiva of patients were evaluated for the need of gingivectomy and gingivoplasty and were done for the
patients that need this operation. Th e sides that applied laser therapies were determined by using coin toss and the other sides were
protected from irradiation by putting at least 5 mm thickness of silicon made appliance. the laser of power 4 J/cm (980 nm) were
applied at 0, 1, 3 and 7 days and the surgical area of all the patients at 0, 3, 7 and 15 days were painted with paint mira-2-tone and the
taken photographs by the Image J programs were evaluated. Clinically, Kolmogorov-Smirnov test was used for checking the normal
distribution of wound healing and VAS results. Willcoxon test and Friedman test were used to compare the dependent two groups or
multiple groups, subsequently. Th e results showed that there were no signifi cant diff erences between groups in SD, KAS, PI, GI, VAS
and wound healing but there were a decreased in VAS values at 3 and 7 days. Th e area that applied DDL showed a decrease in pain.
Aft er this study, 980 nm low level therapy upon the clinical parameters could have a positive eff ects when applied aft er gingivectomy
and gingivoplasty.
