This study is a randomized, controlled, split-mouth clinical trial designed to evaluate and compare the effectiveness of four different subgingival adjuncts used along side standard Scaling and Root Planning (SRP). This protocol is designed to be a standardized therapeutic model. The subgingival adjuncts are standardized, ensuring that the results are not operator dependent and can be replicated across any dental unit. The primary goal of this study is to evaluate the clinical efficacy of three distinct adjunctive strategies: Biological (I-PRF), Antiseptic : Povidone- iodine , Diode-Laser activation, compared to a Saline Control in the initial treatment of stage 2, 3 and stage 4 of the 2018 AAP/EFP periodontal classification.
