TABLE 3.
(A) Full‐mouth plaque scores (FMPS) and full‐mouth bleeding scores (FMBS) at baseline, at re‐evaluation after periodontal regeneration and latest follow‐up (means or percentages ± SD) (n = 38). (B) Mean clinical parameters and frequency distribution (%) of BoP and plaque at the deepest site of the treated teeth which reached the latest follow‐up examination (means ± SD) (n = 68)
