RESUMO
Background The periodontal flap is one of the most frequently employed procedures. Closure of reflected flap is important step in flap surgery. Black silk sutures are most often used material in routine surgical procedures. These suture materials demand more time and effort and expertise from the surgeon. Tissue adhesives have been developed as alternatives to overcome these problems such as cyanoacrylates. Objective The present study is an attempt to compare effectiveness of the black silk suture with cyanoacrylate adhesives in closing reflected periodontal flap. Method Thirty systemically healthy patients who underwent bilateral flap surgery were given 3-0 black silk sutures on one side and N-butyl cyanoacrylate adhesive on the other side to close a surgical incision. All the participants in the study were recalled on the seventh, 21st, 42nd day. Participants were evaluated for healing and plaque accumulation by assessing the gingival index, plaque index, wound healing index. Biopsy specimens were obtained on seventh and 42nd postoperative day. Result The amount of inflammation was less during the first week of healing when cyanoacrylate was compared with silk. However, over a period of 21 days to 42 days, the sites treated with both the materials showed similar healing patterns without any significant difference in the evaluated parameter. Conclusion The result of the study showed that the use of cyanoacrylate for the closure of periodontal flaps results in better initial post-operative healing as compared to closure with silk suture and that this method of closure can be advocated in a routine surgical periodontal practice.
