Abstract

Purpose: This study was made to evaluate and compare the efficacy of photodynamic periodontal therapy and diode laser as an adjunctive approach to conventional periodontal therapy in management of chronic periodontitis. Subjects and methods: 30 patients with chronic periodontitis and age range from 30-40 years old were divided randomly into three groups. Group I (control group) 10 patients received conventional periodontal therapy alone. Group II (laser group): patients received SRP + additional application of a 940-nm diode laser. Group III (photodynamic group): patients received SRP + antimicrobial photodynamic therapy by using low level 670 nm diode laser application in addition to application of 1% toluidine blue as photosensitizer. Results: there were a significant difference of PD, CAL, IL-1β, IL6, NO, NO2 between three groups with superior result found in photodynamic group, but there were no significant differences between three groups in the term of NO3. Conclusion: Diode laser and photodynamic therapies add a beneficial effect in clinical and biochemical parameters when used as adjunctive to scaling and root planning but there was no significant difference between them.
