A questionnaire was sent to diplomates of the American Board of Endodontics to determine changing trends in the treatment of endodontic emergencies since Dorn's survey 10 yr ago. There is a definitely greater trend toward complete instrumentation of the root canals to the apex regardless of the emergency condition than there was a decade ago. The number of respondents who leave teeth open when the pulp is nonvital has dropped dramatically in the past decade. When there is no periapical involvement, over one third of the respondents are completing treatment in one visit. A decrease in the use of classic phenolic medicaments was noted with a corresponding increase in calcium hydroxide or no medication at all.
向美国牙髓病学委员会的专科医师发送了一份调查问卷，以确定自10年前多恩的调查以来牙髓病急症治疗方面不断变化的趋势。与十年前相比，无论急症情况如何，目前将根管完全预备至根尖的趋势明显增强。在过去十年中，当牙髓无活力时仍使牙齿开放的受访者数量大幅下降。当不存在根尖周病变时，超过三分之一的受访者会在一次就诊中完成治疗。结果显示，经典酚类药物的使用有所减少，而氢氧化钙的使用相应增加，或者根本不使用任何药物。
