ABSTRACT
Background: Soft tissue excision around natural teeth is carried out to increase the clinical crown lengths, expose the caries apical to the gingival margins and to correct irregular and un‑esthetic soft‑tissue contours. Aims: The study was carried out with an aim to evaluate the stability of the soft tissue margins after excision either with a laser or scalpel. Materials and Methods: A total of 20 patients indicated for soft tissue excision for correcting soft tissue discrepancies were selected. The patients with thick gingival biotype were included in the study. They were grouped randomly into excision by laser or scalpel methods. The change in the soft tissue positions from the time of excision to 1‑month follow‑up were evaluated immediate postoperatively, after 2 weeks and after 1‑month postrestoration. Results: The soft tissues remained stable in the laser group at 1‑month follow‑up, in contrast to the scalpel group and were found to be statistically significant, (Student’s t‑test) (P < 0.05). Conclusion: The soft tissue margins are more stable and stay at the point they were excised with lasers when compared with scalpel.
ABSTRACT
Cyanoacrylates are tissue adhesives used for closure of surgical wounds. N-butyl cyanoacrylate is a biocompatible tissue adhesive used for closure of surgical wounds. In the present study evaluation and comparison the healing of oral wounds was done when closed with N-butyl cyanoacrylate and silk sutures in a rabbit model. It was found clinically that the sites treated with cyanoacrylate had less inflammation and healed better at 7 days as compared to the sutured sites. At 7 days the histological picture correlated with the clinical findings and the amount of inflammation was less on the cyanoacrylate site. At 21 days both the sites appeared similar clinically and histologically. It is concluded that N-butyl cyanoacrylate tissue adhesive results in faster initial wound healing as compared to silk sutures and can be used for closure of oral wounds.
