The current study was conducted to evaluate the influence of frequently ingested beverages on the stability of suture materials.
This research comprised of two kinds of chromic catgut, polyglactin 910 (4-0) absorbable suture materials. Every specimen was subjected to tying using a square surgeon's knot. Subsequent to pretensioning, 80 suture samples (40 of every material) were employed in this research. Every specimen was subjected to immersion in artificial saliva to replicate the oral atmosphere. Specimens were sunken in the acidic drink (Coca Cola) and tea for 10 min every day. Tensile strengths of the suture specimens were subjected to test at particular time periods: before immersion and 1, 7, and 14 days after immersion. Tensile strength evaluation of the suture specimens was performed employing the microtensile tester at a cross-head speed of 2.0 mm/60 s.
When subjected to exposure to acidic beverages, the tensile strength of chromic catgut suture before immersing was 25.14 ± 0.16, 25.02 ± 0.08 on the first day, 16.34 ± 0.23 on the seventh day, and 9.18 ± 0.28 on the fourteenth day. When the suture substance made contact with tea, the tensile strength before immersing was 24.48 ± 0.02, 24.14 ± 0.16 on the first day, 18.26 ± 0.11 on the seventh day, and 12.39 ± 0.14 on the fourteenth day. When subjected to exposure to acidic beverages, the tensile strength of polyglactin 910 sutures before immersing was 25.21 ± 0.02, 25.08 ± 0.01 on the first day, 18.12 ± 0.06 on the seventh day, and 10.06 ± 0.32 on the fourteenth day. When the suture substance made contact with tea, the tensile strength before immersing was 25.02 ± 0.14, 24.96 ± 0.04 on the first day, 20.48 ± 0.18 on the seventh day, and 14.10 ± 0.08 on the fourteenth day. The differences between the groups were statistically significant.
In conclusion, polyglactin 910 exhibited a maintained strength superior than chromic catgut sutures subsequent to 14 days.
进行本研究以评估经常摄入的饮料对缝合材料稳定性的影响。
本研究包括两种铬制肠线、聚乙醇酸910（4-0）可吸收缝合材料。每个样本均采用外科方结进行打结。预紧后，本研究使用了80个缝合样本（每种材料40个）。每个样本都浸泡在人工唾液中以模拟口腔环境。样本每天在酸性饮料（可口可乐）和茶中浸泡10分钟。在特定时间段对缝合样本的拉伸强度进行测试：浸泡前以及浸泡后1天、7天和14天。使用微拉伸试验机以2.0毫米/60秒的十字头速度对缝合样本进行拉伸强度评估。
暴露于酸性饮料时，铬制肠线缝合线浸泡前的拉伸强度为25.14±0.16，第一天为25.02±0.08，第七天为16.34±0.23，第十四天为9.18±0.28。当缝合材料接触茶时，浸泡前的拉伸强度为24.48±0.02，第一天为24.14±0.16，第七天为18.26±0.11，第十四天为12.39±0.14。暴露于酸性饮料时，聚乙醇酸910缝合线浸泡前的拉伸强度为25.21±0.02，第一天为25.08±0.01，第七天为18.12±0.06，第十四天为10.06±0.32。当缝合材料接触茶时，浸泡前的拉伸强度为25.02±0.14，第一天为24.96±0.04，第七天为20.48±0.18，第十四天为14.10±0.08。各组之间的差异具有统计学意义。
总之，14天后聚乙醇酸910的强度保持优于铬制肠线缝合线。
