The purpose of this investigation was to ascertain the prevailing attitudes within the endodontic community regarding smear layer removal. The first survey asked the philosophies and techniques currently being taught to predoctoral dental students and postdoctoral endodontic residents in the United States, whereas the second surveyed some of the members of the American Association of Endodontists currently practicing in the United States. Findings from these surveys revealed that more than three-fourths of the dental students and nearly two-thirds of the endodontic residents are not being taught routine smear layer removal. Slightly more than one-half of endodontists responded they practice smear layer removal. These surveys indicate that there is no clear consensus in the endodontic community, either academically or clinically, as to whether the smear layer should be removed or be allowed to remain before obturation of the root canal space.
本调查的目的是确定牙髓病学界对于去除玷污层的普遍态度。第一项调查询问了目前在美国牙科博士生和牙髓病学博士后住院医师中所教授的理念和技术，而第二项调查则针对了目前在美国执业的美国牙髓病学家协会的部分成员。这些调查结果显示，超过四分之三的牙科学生和近三分之二的牙髓病学住院医师未被教授常规去除玷污层的方法。略多于一半的牙髓病学家回应称他们会去除玷污层。这些调查表明，在牙髓病学界，无论是在学术上还是临床上，对于在根管空间充填前是否应去除玷污层还是任其保留，都没有明确的共识。
