Bacterial Accumulation on Triclosan-Coated and Silk Sutures After Dental Implant Surgery

Abstract

Background and Aim: The risk of surgical site infection may depend on bacterial attachment and physical and chemical properties of suture materials. This study aimed to evaluate bacterial accumulation on triclosan-coated (Vicryl Plus) and silk sutures placed at different distances from Vicryl Plus after dental implant surgery. Materials and Methods: In this randomized controlled trial, 20 patients who required dental implants were included. Their surgical sites were large enough to include at least four sutures. The surgical site was sutured first with Vicryl Plus and then with three silk sutures placed at 3, 6, and 9 mm distances from Vicryl Plus. Sutures were removed 7 days after surgery, and the samples were placed in microbiological cultures specific to Enterococci and Escherichia coli (E. coli). Subsequently, the numbers of colony-forming units (CFUs) and bacterial growth rates were evaluated. Kruskal-Wallis and Mann-Whitney U tests were used for statistical analysis. Results: There were no significant differences in the number of CFUs and growth rates of microorganisms isolated from triclosan-coated and silk sutures 7 days postoperatively (P>0.05). Conclusion: Triclosan-coated sutures have no benefits over silk sutures placed at different distances from Vicryl Plus.

Effective Factors in Implant System Selection by Dentists in Kerman in 2018: A Cross-Sectional Study

“…Successful osseointegration is an indication of favorable bone response to the insertion of a dental implant. (39) However, the long-term success-ful osseointegration of dental implants in the jawbones is due to the precision of the biomechanics of implants and their superstructure. Implant surface topography and surface roughness, bone-implant interface, implant design, implant length and diameter, geometric features of the edentulous site, and supporting properties of bone have been reported as important factors in the load transfer mechanism and bone-implant response.…”

Gingival Recession Treatment by Free Graft Fixed with Silk Sutures vs Vicryl Plus

“…Vicryl Plus sutures, made of polyglactin 910, are absorbable and braided, and they include triclosan, an antimicrobial agent that helps reduce the risk of infection. In contrast, silk sutures have a long history of use in periodontal surgery and are non-absorbable and braided (5) . Both suture materials have shown adequate performance in FGG procedures.…”

“…Vicryl Plus sutures were developed to fulfill these criteria by integrating the advantages of an absorbable suture material with the additional antimicrobial benefits of triclosan. Besides their antimicrobial features, Vicryl Plus sutures present other benefits, such as their absorbable nature, which removes the need for suture removal and lessens patient discomfort and inconvenience (5) . Moreover, Vicryl Plus sutures have demonstrated lower tissue reactivity compared to non-absorbable sutures, resulting in decreased inflammation and enhanced healing.…”

Bacterial accumulation on different types of suturing materials in periodontal surgery and implantology – literature review.

“…The ideal suture material should have great strength, knot stability, flexibility, should be easy to manipulate, should cause minimal tissue reaction and be resistant to infections 9 . Commercially available materials are classified according to different criteria: three-dimensional structure (monofilament, multifilament), tissue stability (resorbable, non-resorbable) and origin of the material (natural, synthetic) 10 . Suturing materials are potential risk factors for wound infection obtained during periodontal surgery, and their success depends on the primary wound healing and the absence of bacteria at the healing site 11,12 .…”
