Periodontal patients will be treated with Guided Biofilm Therapy. At the baseline (T0), the following clinical indices will be collected: BoP, BS, CAL, PPD. A plaque disclosing agents will be used to instruct the patients to proper oral hygiene procedures. At this stage, using a split-mouth design, quadrants will be randomized to:
Patients will be visited after 1 month (T1) and 2 months (T2), in which the periodontal indexes will be collected again.
After all the procedures, VAS for pain will be assessed, with Schiff Air Index, comfort (patients), comfort (operator), timing for the procedures (minutes), satisfaction questionnaire (for patients and for the operator), consumption of the powders for the two handpiece.
Periodontal patients that respond to the inclusion criteria and agree to participate in the study will be treated with Guided Biofilm Therapy.
At the baseline (T0), the following clinical indices will be collected: BoP, BS, CAL, PPD. A plaque disclosing agents will be used to instruct the patients to proper oral hygiene procedures. At this stage, using a split-mouth design, quadrants will be randomized to:
