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: * Airflow and Scaling and calculus removal with EMS Prophylaxis Master handpiece * Airflow and calculus removal with Mectron Combi handpiece 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: * Airflow and calculus removal with EMS Prophylaxis Master handpiece * Airflow and calculus removal with Mectron Combi handpiece Patients will be visited after 1 month (T1) and 2 months (T2), in which the periodontal indexes will be collected again. Together with periodontal assessment, 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 handpieces.

Change in Schiff Air Index - Dental sensitivity test
Scoring criteria: 0\. the subject did not respond to air blasting; 1. the subject responded to air blasting; 2. the subject responded to air blasting and requested discontinuation; 3. the subject responded to air blasting, requested discontinuation and considered the stimulus to be painful.
Time frame: Baseline, after 30 and 60 days
Change in BOP - Bleeding on Probing (percentage)
Site-specific assessment of the presence or absence of gum bleeding after the insertion of the periodontal probe for the detection of PPD, detected on 4 sites (mesial, distal, vestibular, palatal/lingual).
Time frame: Baseline, after 30 and 60 days
Change in Bleeding Score (BS - Mombelli et al.)
Scoring criteria: 0: no bleeding 1. isolated visible spots 2. blood forms a confluent red line on the mucosal margin 3. profuse and copious bleeding
Time frame: Baseline, after 30 and 60 days
Change in Probing Pocket Depth (PPD)
Evaluation (in mm) of the depth of the gingival sulcus, through a millimeter periodontal probe; it is detected from the gingival margin to the bottom of the gingival sulcus or periodontal pocket, evaluated at 6 sites.
Time frame: Baseline, after 30 and 60 days
Change in CAL - Clinical Attachment Loss
Measurement (in mm) of the position of the gingival margin in relation to the cemento-enamel junction (CEJ).
Time frame: Baseline, after 30 and 60 days
Total time of usage
Total time of usage of the two handpieces.
Time frame: Baseline
