A summary of the PES/WES outcome is depicted in Table 4 . There was statistically no significant change in PES or WES between the first month (T 1 ) and 12 months (T 12 ) after definitive crown placement. The change in mid-buccal mucosa height between T1 and T12 was -0.14±0.40 mm. There was an overall gain in papilla height: +0.05±0.60 mmmesially and +0.06±0.53 mm distally. There was not a significant difference in mid-buccal mucosa level and in papilla height between the first month (T1) and 12 months (T12) after definitive crown placement. a b c d
