This study aimed to determine the efficacy of papilla reconstruction using a connective tissue graft with either a semilunar coronally repositioned flap or envelope flap. Twelve adult patients with 14 Class I interdental papilla defects were randomly divided into two groups. group 1 received a connective tissue graft with a coronally repositioned flap, while group 2 received a connective tissue graft with an envelope flap. The distance between the tip of the papilla and alveolar bone crest as well as the horizontal interdental distance at the tip of the papilla were recorded at baseline and after 3 and 6 months. groups were compared using repeatedmeasures analysis of variance and the Tukey post hoc test. The mean increase in papilla height was 2.36 ± 0.90 mm for group 1 and 2.00 ± 0.91 mm for group 2. The mean decrease in horizontal interdental distance at the tip of the papilla was 1.00 ± 0.00 mm for group 1 and 0.86 ± 0.24 mm for group 2. Both treatment modalities resulted in significant improvements in papilla height. There were no significant differences between the two groups. (Am J Esthet Dent 2012;2:256–262.)
