Pink Esthetic Score (PES)
PES
Examiners applied the PES index used by Fürhauser [The esthetic evaluations of the soft tissue PES were evaluated by two assessors (M.T) and (R.W) who were not part of the treatment procedures. The assessors were calibrated before the study on 20 single implant cases, then after 1 week, asked to reexamine the same cases in a different order. The frontal color pictures were re-scored twice with an interval of 1 week. Furthermore, the intra-examiner reproducibility was evaluated.
