A series of 359 endodontic cases were followed and evaluated by the frequency of reported postoperative pain. A statistical analysis of the data obtained attempted to identify a relationship between pain experienced and the anatomic location, the pulpal vitality as determined by hemorrhage, or the number of treatment visits used in completing the case. Data obtained indicated no relationship between pain experience and pulpal vitality, no statistically significant relationship to the anatomic location, and a significant relationship to the number of visits used. The data indicate a 2 to 1 higher frequency of pain reported following treatment completed in multiple visits as compared to that reported for those completed in one visit.
对359例牙髓病治疗病例进行了跟踪，并根据术后疼痛报告的频率进行评估。对所获得的数据进行统计分析，试图确定所经历的疼痛与解剖位置、由出血情况确定的牙髓活力或完成病例所需的治疗次数之间的关系。所获得的数据表明，疼痛经历与牙髓活力之间没有关系，与解剖位置没有统计学上的显著关系，而与治疗次数有显著关系。数据表明，多次就诊完成治疗后报告的疼痛频率比一次就诊完成治疗后报告的疼痛频率高2倍。
