Originally, Clark's rule was used to identify the position of unerupted or supernumerary teeth (a concept known as oral localization) prior to orthodontic tooth movement or surgical removal. However, the versatility of this rule's principles and concepts are also highly applicable to endodontic diagnosis and treatment. While contemporarily known by many different names, such as the "buccal object rule" and the "cone beam-shift technique," the importance of this rule in endodontics was not recognized in the literature until late in the 20th century, despite historical evidence demonstrating its incorporation into root canal procedures almost 100 years ago.
最初，克拉克法则用于在正畸牙齿移动或手术拔除之前确定未萌出或多生牙的位置（这一概念称为口腔定位）。然而，该法则的原理和概念的通用性在牙髓病诊断和治疗中也具有高度适用性。虽然现在它有许多不同的名称，如“颊侧物体法则”和“锥形束移位技术”，但直到20世纪末，该法则在牙髓病学中的重要性才在文献中得到认可，尽管有历史证据表明它在近100年前就已被纳入根管治疗程序。
