Effect of cyanoacrylate tissue adhesive in postoperative palatal pain management: a systematic review.

Abstract

To critically appraise available literature concerning the effect of cyanoacrylate tissue adhesive (CTA) in postoperative palatal pain management. Electronic databases (Cochrane, PubMed, LILACS, Scopus, and Web of Science) were searched, complemented with grey literature databases up to June 2020. Studies reporting the effect of cyanoacrylate tissue adhesive compared to any other methods in postoperative palatal pain management were considered eligible. The risk of bias among and across included studies was assessed. Finally, four studies were considered eligible. Regarding free gingival graft (FGG), cyanoacrylate tissue adhesive with hemostatic sponge promoted less postoperative pain (PP) and analgesic consumption (AC). Also, cyanoacrylate tissue adhesive with platelet-rich fibrin produced less PP and more wound healing at the palatal area than cyanoacrylate tissue adhesive and wet gauze. Additionally, cyanoacrylate tissue adhesive promoted less PP and AC than wet gauze and suture. Concerning connective tissue graft (CTG), cyanoacrylate tissue adhesive, and suture produced similar PP, AC, and willingness for retreatment. Based on the low certainty level, cyanoacrylate tissue adhesive appears to promote less PP and AC than wet gauze and suture regarding FGG. Additionally, cyanoacrylate tissue adhesive appears to increase the effect of hemostatic sponge, contributing to the reduction of PP and AC. Regarding CTG, cyanoacrylate tissue adhesive appears to promote similar PP, AC, and willingness for retreatment than the suture. Therefore, cyanoacrylate tissue adhesive has shown promising usefulness for PP management in FGG, but not a clear benefit for CTG. The adoption of different agents for the protection of the palatal donor site following gingival harvesting procedures may provide better comfort to the patient.
