The coronally advanced flap in the treatment of bilateral multiple gingival recessions with or without tunneling the maxillary midline papilla: a randomized clinical trial. J Oral Science Rehabilitation. 2016 Mar;2(1):56–61. Abstract O b j e c t i v e The objective of this study was compare the clinical results of the coronally advanced flap (CAF) without vertical releasing incisions using (i) a tunneling procedure on the maxillarymid- line papilla (test) or (ii) a conventional technique (control) in whichthe midline papilla is incised and elevated like anyother papilla in the procedure. M a t e r i a l s a n d m e t h o d s Twenty healthy subjects with at least two Miller Class I gingi- val recessions (RECs) crossing the midline in the maxilla were enrolledforthestudy.Fifty-six(meaninitialREC=2.3±0.9mm) and 75 (mean initial REC = 2.3 ± 1.1 mm) RECs were treated in thetest and control groups, respectively.All ofthe caseswere treated by means of CAF without vertical releasing incisions: ten were randomly assigned to the test group and ten to the control group. Clinical evaluations in terms of REC were per- formed at baseline (preoperative) and after one year.

R e s u l t s The mean final REC at 12 months for the test group was 0.3 ± 0.5 mm and for the control group 0.4 ± 0.6 mm, with a RECred of 2.1 ± 0.9 mm (89.1% of the initial REC) and of 1.9 ± 0.9 mm (84.3% of the initial REC), respectively. For- ty-three out of 56 (76.8%) RECs in the test group and 53 out of 75 (70.7%) in the control group achieved CRC. The initial mean REC at the central incisors was 2.3 ± 0.9 mm and 2.7 ± 1.2 mm, respectively,forthetest and control groups. The mean final REC after 12 months was 0.3 ± 0.6 mm and 0.4±0.6mm,respectively,forthetestandcontrolgroupswith a RECred from the baseline of 2.0 ± 0.9 mm (87%) forthe test group and of2.3 ± 1.0 mm (87%)forthe control group. Fifteen out of 20 (75%) RECs in the test group and 14 out of 20 (70%) in the control group achieved CRC. C o n c l u s i o n There was no statistically significant difference between the two groups for RECred and CRC for either all of the RECs or those at the central incisors only.
