Efficacy of Photodynamic Therapy and LASER Disinfection as Adjunct to Nonsurgical Periodontal Therapy for Treatment of Periodontitis: Randomized Clinical Trial
The goal of this clinical trial is to Investigate the clinical and microbiological efficacies of Laser disinfection and ICG-mediated aPDT as adjunct to RSD for patients with periodontitis. The main question it aims to answer is: Does the use of laser disinfection or ICG-mediated aPDT as adjunct to RSD are effective in improving clinical parameters and reducing the load of periodontal pathogens. Participants will undergo full-mouth supragingival debridement by using ultrasonic device at baseline. All patients will be instructed to brush their teeth twice daily and will be supplied with the same type of tooth paste and toothbrush, with suitable interdental aids. All the patients will be instructed to attend again after 7 days. One week later, sites randomly allocated to control (Ctrl) group and test groups which will receive, in addition to RSD, either aPDT or periodontal pocket disinfection (Biolase). For all groups, sites with initial PPD 4-6 mm will be treated with RSD using area specific (Graecy) curettes.
• Adult subjects (\>18 years), non-smoker, with no history of any systemic disease such as diabetes mellitus. Additionally, subjects are not currently under active periodontal therapy or joining other trial in the last 3 months. All patients must be diagnosed with generalized periodontitis with at least 3 teeth in three different sextants (Anterior teeth and premolars) with 4-6 mm PPD and positive BOP. Periodontitis cases will be defined by presence of interdental CAL affecting ≥2 non adjacent teeth or if CAL at buccal/lingual aspects associated with PPD \>4mm at ≥2 teeth.
