PLAQUE
At baseline (T0) and 3 months after treatment (T1) PD, clinical attachment level, gingival recession, BoP, and the presence of supragingival plaque (PII) were collected by a blinded examiner at 6 sites (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual, disto-lingual) for each tooth present. For each patient, all sites that showed PD 5–9 mm and were BoP-positive at T0 were identified as experimental sites.Interventions were performed by the same two experienced calibrated operators (ES and CF).Test group was identified according to the generated randomization table at the start of the session. After the application of a disclosing agent (Mira-2-Ton®, Hager & Werken, Duisburg, Germany) to guide plaque removal and achieve better biofilm removal[
