Anti-adhesion activity and physicochemical features of the surgical silk sutures coated with Liquidambar orientalis styrax

Abstract

Aim: The present study was aimed to characterize the surgical silk sutures coated with Styrax liquidus, Turkish sweetgum balsam obtained from Liquidambar orientalis, and to investigate their anti-adhesion capacity against oral pathogenic microorganisms.Material and Methods: Fourier Transform Infrared Spectroscopy (FTIR) was applied to determine the chemical composition of the Liquidambar orientalis styrax (LOS)-coated sutures. Thermogravimetric Analysis (TGA) was performed to compare the thermal stability of the LOS-coated sutures. Scanning Electron Microscopy (SEM) was used to evaluate the morphological structure of the sutures. Anti-adhesion activity of the LOS-coated sutures was investigated against common oral pathogenic microorganisms.Results: FTIR spectrum and SEM images revealed out that LOS was succesfully coated onto the silk sutures. TGA analysis showed that LOS coating moderately affected the thermal stability of the silk sutures. According to the anti-adhesion activity analysis, the highest activity was observed against S. aureus, a gram positive bacteria.Conclusion: Coating the surgical silk sutures with LOS might be useful to prevent the surgical site infections in oral surgery.
