Evaluation of Tensile Strength of Sutures Used in Dentistry

Abstract

Aim: The aim of this study was to compare the mechanical properties of sutures used in dentistry according to different materials in vitro. Material and Methods: Eight 3-0 different absorbable and non-absorbable suture materials with 3-0 gauge (Polytetraflouroethylene, polypropylene, polyester, polyglactin 910, polyglycolic acid, poliglecaprone 25, polydioxanone, and silk) were compared in terms of mechanical strength. All sutures were tied with a simple suture technique. Each material contained 10 samples per group, with a total sample size of 80 specimens. Failure load was measured in N while elongation was measured in µm using a microtensile testing device. A one-way analysis of variance (ANOVA) was used to analyze the difference in failure loads and elongation values. Results: Polydioxanone was significantly more resistant to tensile forces among all tested materials (p
