The first step in the management of periodontal disease involves the non-surgical removal of the soft and hard bacterial deposits at all supra- and sub-gingival sites, especially into deep pockets, which can be carried on with different instruments. Unfortunately it seems that, after the initial therapy, many patients still present with active pockets (residual pockets) requiring further treatment and posing a risk of disease progression. This might be due to limitations of the instruments applied and patient-related factors. Air-polishing with low-abrasiveness powders seems to be very effective in the removal of supra- and sub-gingival biofilm and could provide additional benefits during the treatment of pockets. The aim of this randomized, controlled, split-mouth study was to compare the efficacy of full-mouth air-polishing followed by ultrasonic debridement (GBT) versus traditional Scaling and Root Planing (SRP), in terms of pocket closure in patients with stage III-IV periodontitis. To test this hypothesis, the mouth of each patients, upon initial evaluation, were divided in 2 parts: 1. The control group undergoing a standard procedure: ultrasonic debridement with an ultrasonic scaler for remove supra and sub gingival calculus, manual debridement with curettes at deep pathological pockets (PPD > 4mm) and rubber cup with polishing to remove supra gingival biofilm and plaque. 2. The study group undergoing the innovative air polishing procedure: airflow with erythritol powder to remove supra and sub gingival biofilm and plaque, perioflow at deep pathological pockets (PPD > 4mm) and ultrasonic debridement with an ultrasonic scaler for remove supra and sub gingival calculus. The prevalence of residual pockets will be evaluated at 6 weeks and 3 months after the initial therapy and compared between the two groups.

Primary | The number of experimental sites (PPD > 4mm and <10mm) becoming closed pockets (PPD = 4mm). | A 10% difference in the primary outcome between the two protocols was set as the threshold to define inferiority/non-inferiority of the Test treatment. | 3 months after initial therapy. | |
Secondary | Change in PPD (periodontal depth) | Change in mean PD value for each patient measured (from the gingival margin to the bottom of the pocket). Baseline values will be compared to the values recorded in the follow-up visits. | 3 months after initial therapy. | |
Secondary | Change in REC (Clinical Gingival Recession) | Change in mean of REC value for each patient should be calculated. Baseline values will be compared to the values recorded in the follow-up visits. | 3 months after initial therapy. | |
Secondary | Change in CAL (Clinical Attachment Level) | Change in mean of CAL value for each patient should be calculated. Baseline values will be compared to the values recorded in the follow-up visits. | 3 months after initial therapy. | |
Secondary | Change in BOP (Bleeding on Probing) | Change in percentage of sites positive to bleeding on probing. Baseline values will be compared to the values recorded in the follow-up visits. | 3 months after initial therapy. | |
Secondary | Change in PI (Plaque Index) | Change in percentage of site with plaque. Baseline values will be compared to the values recorded in the follow-up visits. | 3 months after initial therapy. |
