Summary

The current experimental protocol is a pre-post quasi-experimental design. A cohort of individuals will be enrolled progressively according to a screening record of periodontitis. They were treated with PMPR and Subgingival Instrumentation according to their diagnosis. After 3 months they will be re-evaluated, and non-responding sites (Ppd\>=4mm and bop+) will be scheduled for the second session of PMPR and SI. After 2 months they will be re-evaluated and clinical efficacy will be defined.

Detailed description

The current experimental protocol is a pre-post quasi-experimental design. A cohort of individuals will be enrolled progressively according to a screening record of periodontitis. Once included, individuals will receive, by a calibrated examiner, a full-mouth periodontal chart, and accordingly, they will be treated in a multi-step approach, in accordance with the recent clinical guidelines. The treatment will consist of oral hygiene instruction and motivation, risk factor control, professional mechanical plaque removal (PMPR), and subgingival instrumentation (SI): it will be performed by two experienced operators. Thereafter, after 3 months, patients will be evaluated and a new periodontal chart will be performed. The presence of non-responding sites (Ppd\>4 and bop+) will be treated with the second session of PMPR plus Subgingival Instrumentation. After 2 months patients will be clinically evaluated and a full periodontal chart will be completed.
