Clinical Effects of Photodynamic and Low‑Level Laser Therapy as an Adjunct to Scaling and Root Planning of Chronic Periodontitis

Abstract

The aim of this study is to evaluate the clinical effects of PDT, as adjunct to conventional SRP alone in the treatment of chronic periodontitis. Three patients (2 females and one male ) ,with age: ranging from 18–60 years were selected for the study .Thirty site were examined for patient Plaque index (PI),Gingival index (GI), PDs, and The probing pocket depth and CALs were measured using graduated periodontal probe . The subjects were divided in to three group SRP, single episode of PDT using 1% MB solution and LLLT using a a diode laser • Group II: SRP and single episode of PDT using 1% MB solution as a photosensitizer • Group III: SRP only. The obtained results indicated that patients treated with the SRP, single episode of PDT using 1% MB solution and LLLT had less plaque index gingival index and clinical attachment loss when compare d to patients treated with SRP and 1% MB solution as a photosensitizer a and those treated with SRP only (0.001). Based on the results, it can be concluded that treatment of periodontal pocket with the SRP, single episode of PDT using 1% MB solution and LLLT provides less plaque index gingival index and clinical attachment loss when compare d to patients treated with SRP and single episode of PDT using 1% MB solution as a photosensitizer a and those treated with SRP only.
