A prospective, randomised and controlled clinical investigation was undertaken to evaluate the longevity of resorbable sutures in the oral environment. The sutures investigated were gut, polyglycolic acid and polyglactin 910, were of standard gauge and needle type, and were placed using a standard technique by trained clinicians. The sutures were monitored following apical surgery in 55 patients (110 sutures) and the median survival values were: gut - 4 days, polyglycolic acid - 15 days, polyglactin 910 - 28 days. These differences were highly statistically significant. A postal survey of 30 randomly selected oral and maxillofacial surgeons reveal most prefer to use resorbable sutures, with softgut the most popular choice. Most would like an ideal resorbable suture to last 5 to 14 days and in this respect none of the materials tested appears satisfactory.
进行了一项前瞻性、随机对照临床研究，以评估可吸收缝线在口腔环境中的使用寿命。所研究的缝线为肠线、聚乙醇酸和聚乳酸910，规格和针型均为标准型，由训练有素的临床医生采用标准技术进行放置。对55例患者（110根缝线）进行根尖手术后对缝线进行监测，中位存活时间分别为：肠线4天，聚乙醇酸15天，聚乳酸910 28天。这些差异具有高度统计学意义。对30名随机挑选的口腔颌面外科医生进行的邮政调查显示，大多数人更喜欢使用可吸收缝线，其中软肠线是最受欢迎的选择。大多数人希望理想的可吸收缝线能持续5至14天，在这方面，所测试的材料似乎都不尽人意。
