COMPARISON TENSILE STRENGTH OF DIFFERENT SUTUR MATERIALS

Abstract Objectives: The purpose of this study is to compare the tensile strength of different types of surgical suture materials. Materials and Methods: Current study, the tensile strengths of 4 different suture materials made of different materials were compared. [(1-4/0 silk suture 2- 4/0 propylene suture 3-4/0 Polyamide suture 4- 4/0 Poly[Glycolide-Co-L-Lactide](90%:10%) (PGLA) suture)] The tensile strength of a total of 40 samples was calculated, with 10 samples in each group. In the study, the tensile strength of the sutures was calculated using a universal tester, the sutures were tightened to both poles of the test device and fixed with a distance of 15 mm between the poles, tensile force was applied so that both poles of the test device moved away from each other at a speed of 25cm/min until the sutures broke, and the force value of the sutures at the moment of brake was recorded in Newton units (N) as the tensile strength of suture.Statistical analysis of the data was evaluated by One-Way ANOVA and Tukey HSD tests. Results: In the statistical analysis of the tensile strength of the suture materials, the difference between the tension resistance of the PGLA and Polyamide suture was not statistically significant, but the difference between all other suture materials was statistically significant (p <0.05). Tensile strength of suture materials were determined as propylene, polyamide, pgla and silk suture, respectively. Conclusion:Within the limitation of this study.It has been stated that propylene suture may be more advantageous than PGLA, silk ,polyamide suture. Keywords: Sutures ,Tensile ,Break
