Abstract

Background. This study was conducted to compare the pain levels in patients and the clinical efficacy of grafts obtained using two techniques, namely de-epithelialized gingival graft (DGG) and subepithelial connective tissue graft (SCTG), in combination with coronally advanced flap (CAF) for the treatment of multiple adjacent gingival recessions. Methods. Twelve patients were treated using DGG + CAF on one side and SCTG + CAF on the other. The patients’ pain levels at the surgical site, the number of analgesics taken on days 3 and 7, the mean root coverage (MRC), the percentage of complete root coverage (CRC), color match, and gingival thickness (GT) at the graft recipient site were evaluated 6 months after surgery. Results. The total number of analgesics taken during the 7-day period after surgery and pain levels at the surgical site from day 3 to day 7 were significantly higher in the DGG + CAF group compared to the SCTG + CAF group (P = 0.001). In the 6-month follow-up, color match and CRC were significantly higher in the SCTG + CAF group, while GT was significantly higher in the DGG + CAF group. There was no significant difference in MRC between the two groups. Conclusion. The pain and analgesic consumption levels were higher in the DGG + CAF group compared to the SCTG + CAF group, and the recipient site had a weaker color match. However, this technique can lead to a greater increase in the thickness of the grafted area. © 2023 The Author(s).
