Wilcoxon Signed Ranks Testshowed there are no significant differences in the clinically relevant esthetic outcomes between the two time points (p > 0.05). Fig. (1) presents the cumulative percentages of the PES for the baseline and follow-up sessions. The limits that separate each clinically relevant category are represented using dotted lines.
