Clinical and Patient Centred Outcome Performance of Full Mouth Ultrasonic Debridement Carried Out for the Treatment of Periodontitis Performed Either by Piezoelectric or Magnetostrictive Device. A Randomized Controlled Clinical Trial

Patients diagnosed with periodontitis will be assessed for eligibility criteria. Full-mouth periodontal assessment will be performed by an examiner to detect severity and extension of the disease. Thereafter, patient will receive oral hygiene instruction and a closed envelope with patient allocation will be opened. After the allocation to the intervention group, full-mouth ultrasonic debridement will be delivered to the patient by an operator and information about patient perception will be collected. Three months later, patients will be recalled for a new periodontal assessment.
