This study evaluated the surface integrity of sutures after immersion in mouthrinse or water, by scanning electron microscopy (SEM) analysis. Pieces of resorbable suture remaining after oral surgery were immediately collected. Twelve pieces each of catgut, chromed catgut, and polyglactin 910 were divided into four groups and immersed in pure mouthrinse, mouthrinse diluted in water at 1:1 and 1:2, or water (positive control), for 24 h. Three pieces each of new sutures were used as negative control. Specimens were placed on stubs and sputter coated with gold for SEM analysis. Observation of experimental groups and comparison with controls revealed that immersion in the mouthrinse at different dilutions did not alter their surface; slight, nonsignificant changes were found in some experimental specimens yet also in the positive control group. It was concluded that immersion of resorbable sutures in water or non-alcoholic benzydamine hydrochloride mouthrinse did not produce any significant change; therefore, this mouthrinse may be safely employed after oral surgery.
本研究通过扫描电子显微镜（SEM）分析，评估了缝线在漱口水或水中浸泡后的表面完整性。口腔手术后立即收集剩余的可吸收缝线片段。将羊肠线、铬制羊肠线和聚乙醇酸910缝线各12段分为四组，分别浸泡在纯漱口水、1:1和1:2水稀释的漱口水或水（阳性对照）中24小时。每组使用三段新缝线作为阴性对照。将标本放置在短柱上，溅射镀金后进行SEM分析。实验组的观察结果与对照组比较显示，不同稀释度的漱口水浸泡并未改变其表面；在一些实验组标本以及阳性对照组中发现了轻微、无显著意义的变化。得出的结论是，可吸收缝线在水或不含酒精的盐酸苄达明漱口中浸泡不会产生任何显著变化；因此，这种漱口水在口腔手术后可安全使用。
