Aim The present randomized clinical trial compared the long‐term results of subepithelial connective tissue graft ( SCTG ) versus acellular dermal matrix allograft ( ADMA ) in treatment of gingival recessions. Materials and Methods In 16 patients with bilateral Miller Class I/ II gingival recessions, one side was treated with SCTG and the other side with ADMA . Clinical parameters were measured at baseline, 6 months, and at 5 years post‐surgery. Results Fifteen patients completed the study. At 6 months, all parameters showed significant improvement in ADMA and SCTG groups [complete root coverage ( CRC ): 73.3% versus 26.7%, p = 0.027; reduction of recession depth ( RD ): 2.6 ± 1.1 mm versus 2.2 ± 1.1 mm, p = 0.376; reduction of recession width ( RW ): 3.0 ± 1.4 mm versus 2.4 ± 1.4 mm, p = 0.207 respectively]. At 5 years, significant relapses were detected in CRC and reduction of RD and RW in both groups with no statistically significant difference ( CRC : 20.0% versus 13.3%, p = 1.00; RD : 1.6 ± 1.2 mm versus 1.5 ± 1.4mm, p = 0.838; RW : 1.8 ± 1.4 mm versus 1.3 ± 1.5mm, p = 0.367). Patients practicing horizontal toothbrushing habit showed more relapse ( OR = 11.2; p = 0.01). Compared with baseline, the gingival width ( GW ) did not increase in ADMA ‐treated sites ( p = 0.903). Conclusion Five‐year results of SCTG and ADMA were similar in terms of CRC and reduction of RD and RW . Both techniques showed a significant relapse associated with returning to horizontal toothbrushing habit. Increase of GW was stable in SCTG ‐treated sites, but reached to pre‐surgical values in ADMA ‐treated cases.
