Objectives: The present in vitro study sought to evaluate the effect of saliva on the tensile strength of the commonly used suture material over a period of two weeks. Three suture materials Silk (SL), polyglactin 910 (PG) and polypropylene (PP) were used in 4-0 gauge. Methods: A total of 120 suture samples (40 from each material) were used for the experiment. Artificial saliva was mixed with human serum in 1:1 to simulate oral environment. All samples were tested at preimmersion (baseline), 3rd, 7th and 14th day post-immersion period. Universal testing machine was used to test the selected mechanical properties. Results: The distribution of mean baseline tensile strength was significantly higher in PP group (P-value<0.001). Inter-group comparison revealed that PP group has maximum tensile strength when.. Read More»
