Abstract
ABSTRACT:Background: The present study is aimed to describe a six- mouths result on selected microbiological and clinicalparameters obtained by subgingival debridement in periodontitis.Material and Methods: Thirty patients with moderate to advanced periodontal destruction were treated under localanesthesia and the quadrants were randomly allocated in a spilt-mouth design to receive one of 2 types oftreatment procedure: 1- Scaling and root planning (SRP) using hand instrument, and 2- Scaling and root planning(SRP) and then irradiated with (Ga As) infrared diode laser. The selected teeth were assessed for microbiological andclinical variables. Clinical measurements of plague index (PI), gingival index (GI), bleeding on probing (BOP), probingdepth (PD) gingival recession (GR) and clinical attachment level (CAL) were made prior to and at 3 and 6monthsafter treatment. Subgingival plague samples were taken at each appointment and analyzed using dark fieldmicroscopy for the presence of cocci, non-motile rods, and spirochetes. Differences in clinical parameters andprevalence of bacterial species were analyzed using the paired t-test.Result: The mean value of BOP decreased in the laser group (SRP/L) from 59% at baseline to 20% after 6 month (P<0.001) and in SRP group from 55% at baseline to 25% after 6 months (p<0.001). The mean value of PD decreased inthe laser group from 5.0 7± ز 0 mm at baseline to 2.9 0.6± mm after 6 months (P < 0.001) and in SRP group from 5.0 to0.6 mm at baseline to ± 3.3 0. after 6 months (p<0.001). The mean value of the CAL decreased in the laser group from6.8± 1.0 mm at baseline to 4.5±1.0 mm after 6 months (P < 0.001) and in the SRP group from 6.9 1.0± mm at baseline to5.4 1.0± after 6 months (P.(0.001>The reduction of the BOP score and the CAL improvement was significantly higher inthe laser group than in the SRP group (P<0.05، P<0.001, respectively). Both groups showed a significant increase ofcocci and non-motile rods and a decrease in the amount of motile rods and spirochetes.Conclusions: With in the limits of this study soft laser therapy provided additional microbiological and clinical benefitsover conventional mechanical debridement.Key words: Low energy laser, scaling, periodontal root planning.
