Abstract
The goal of the present study was directed to evaluate and compare the clinical, immunological and microbiological effect of diode laser with and without photosensitizing agent as adjunct to SRP in management of patients with LAP Forty-five sites in fifteen medically free patients with LAP of both genders aged 18 35 years old were selected from the Periodontology Clinic, Faculty of Dentistry Tanta University to be enrolled in the current study. All participants received basic periodontal treatment including, full mouth SRP and oral hygiene instructions. Reevaluation was carried out at 3 and 6 months from the initial therapy The three sites in each patient received three modalities of treatment as follow group І: Sites received SRP alone group II: Sites received combined therapy of SRP plus Laser therapy which was done after SRP according to the laser machine manufacturer’s instruction The pockets were irradiated by a 300μm fiber using diode laser 808 nm wavelength, the laser light 1.0 W ,0.05 kHz for about 30 seconds in repeated application (0,7days,21 days group ІІІ: Sites received combined therapy of SRP plus PDT where the photosensitizer injected into the periodontal pocket, then all pockets irradiated by a 300μm fiber using diode laser 808 nm wavelength, 0.3 W power output and 0.05 kHz in a circular pattern for about 40 seconds according to laser machine instructions in repeated application (0,7days,21 days).
