The treatment of periodontitis requires the removal of dental biofilm through both professional mechanical plaque removal and at-home oral hygiene practices. This study aims to compare clinical and psychological outcomes following professional treatment using either piezoelectric or magnetostrictive ultrasonic devices.

Patients diagnosed with periodontitis will be screened for eligibility criteria. A comprehensive full-mouth periodontal assessment will be conducted by a calibrated examiner to determine the severity and extent of the disease. Subsequently, patients will receive oral hygiene instructions, and group allocation will be revealed using a sealed envelope. Based on the assigned group, full-mouth ultrasonic debridement will be performed by a trained operator. Patient perceptions regarding the treatment will then be recorded. After three months, patients will return for a follow-up periodontal evaluation.

Inclusion Criteria:

• >18 years
• periodontitis of stage 1 and 2
• absence of systemic chronic disease

Exclusion Criteria:

• anticoagulants treatment
• antibiotic treatment 3 months before the screening visit
