The removal of the infectious process caused by an abscess in the periapical tissues was a challenge to dentists in the early part of the 20th century. While they recognized the need to debride the periapical tissues, the process was slow, tedious, and often fraught with failure that resulted in tooth extraction. However, with some creative ingenuity, an irrigation-suction apparatus was developed in the 1930s that enabled rapid and thorough debridement. This appliance went through multiple developmental permutations and was successful in achieving the desired goal. Interestingly, while the purpose of this device was a controlled periapical debridement through the root canal, and not necessarily a focus on a cleaning of the intricacies of the root canal system, the basic concept purported was similar to contemporary approaches used in root canal debridement today.
在20世纪初，去除根尖周组织脓肿引起的感染过程对牙医来说是一项挑战。虽然他们认识到需要对根尖周组织进行清创，但这个过程缓慢、繁琐，而且常常充满失败，最终导致拔牙。然而，凭借一些创造性的智慧，20世纪30年代开发了一种冲洗-抽吸装置，能够实现快速彻底的清创。该装置经历了多次改进，成功实现了预期目标。有趣的是，虽然该装置的目的是通过根管进行可控的根尖周清创，而不一定专注于清洁根管系统的复杂结构，但其基本理念与当今根管清创中使用的现代方法相似。
