Immunohistochemical Comparison of Indermil with Traditional Suture Materials in Dental Surgery

Abstract

The aim of this experimental study was to evaluate the effects of indermil on the closure of oral mucosa wounds in comparison with conventional sutures by investigating interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) markers immunohistochemically in an animal model. The animals were anesthetized by intraperitoneal injection of ketamine (90 mg/kg body weight). Straight incisions were made to the buccal mucosa of the animals. Animals were randomly assigned to 5 groups. Five different materials were used in the study. These were silk, plain catgut, monocryl, vicryl rapide (polyglactin 910), and indermil (N-butyl-2-cyanoacrylate). The wounds were closed primarily. After the region of wounds was examined clinically at the 2nd, 7th, 14th, and 21st days, excisional biopsies were performed, and the tissue samples were examined histopathologically and immunohistochemically. On the 14th day, TNF-α and IL-1β levels were high in the plain catgut group, moderate in the indermil group, and mild in the monocryl, silk, and vicryl rapide groups. On the 21st day, TNF-α and IL-1β levels were moderate in the plain catgut group, mild in the indermil and monocryl groups, and nonsignificant in the silk group. After the second day, TNF-α and IL-1β levels were mild in the monocryl, silk, and vicryl rapide groups. Plain catgut had more negative effects than indermil on wound healing. Indermil should be applied to oral mucosa wounds together with sutures to provide better tissue support. Copyright © 2011 by Mutaz B. Habal, MD.
