Sutures are used for the approximation of incised flaps, assistance in primary healing, and hemorrhage control. In oral and periodontal surgery, the appropriate selection of suture material is vital for favorable healing.The aim of the present in-vitro experiment was to evaluate the tensile strengths of 4 different types of suture materials (silk, polygalactine 910, polypropylene, chromic catgut) by simulating potential short-term intraoral exposure to various beverages (saliva, Arabic coffee, tea, cola).A total of 280 suture specimens were prepared, out of which 10 specimens from each group were selected for pre-immersion testing. Remaining suture specimens were immersed in 4 different thermostatically controlled media (1 control [artificial saliva], 3 tests [Cola drink, Arabic coffee, Tea]). Tensile strength was measured at pre-immersion, 3, 7, and 14 days using a universal tensile testing machine. The maximum load required to break the suture material was recorded in Newton.At day 3, tea caused significant reduction in tensile strength of silk and cola caused significant reduction in tensile strengths of polygalactine 910 and chromic catgut. Whereas, at day 7, silk and polypropylene retained their tensile strengths better than others.The authors recommend precaution in the use of these beverages in the first postoperative week, to avoid adverse effect on the mechanical strength of sutures. When exposure to these beverages are anticipated, it is better to use polypropylene sutures that resists rapid fall in tensile strengths in the early postoperative period.
缝线用于缝合切开的皮瓣、促进一期愈合以及控制出血。在口腔和牙周手术中，正确选择缝线材料对良好愈合至关重要。本体外实验的目的是通过模拟缝线在口腔内短期接触各种饮料（唾液、阿拉伯咖啡、茶、可乐）的情况，评估4种不同类型缝线材料（丝线、聚乙醇酸910、聚丙烯、铬制肠线）的拉伸强度。共制备了280个缝线样本，每组从中选取10个样本进行预浸泡测试。其余缝线样本浸泡在4种不同的恒温控制介质中（1种对照[人工唾液]，3种测试[可乐饮料、阿拉伯咖啡、茶]）。使用万能拉伸试验机在预浸泡时、3天、7天和14天时测量拉伸强度。记录使缝线材料断裂所需的最大负荷，单位为牛顿。在第3天，茶导致丝线的拉伸强度显著降低，可乐导致聚乙醇酸910和铬制肠线的拉伸强度显著降低。而在第7天，丝线和聚丙烯比其他材料更好地保持了它们的拉伸强度。作者建议在术后第一周使用这些饮料时要谨慎，以避免对缝线的机械强度产生不利影响。当预计会接触这些饮料时，最好使用聚丙烯缝线，这种缝线在术后早期能抵抗拉伸强度的快速下降。
