Clinical assessment
PD, bleeding
BLEEDING, PLAQUE
Clinical measurements were performed at three time points: at baseline, at 3 months and at 6 months. The following clinical parameters were assessed: full mouth plaque index (FMPI), bleeding on probing (BOP), probing depth (PD) and gingival recession (REC). Clinical attachment loss (CAL) was calculated as a sum of PD and REC at respective sites. All measurements were carried out using a manual 1-mm graduated periodontal probe (PCP-UNC 15, Hu-Friedy) and recorded at six sites. A trained and calibrated examiner (N.L.) performed all assessments at baseline and at all follow-up time points. The examiner reliability was high with agreement in assessment on all clinical parameters of above 80% (ICC > 0.80).
