A clinical investigation was conducted to compare the incidence and severity of postoperative pain in single-visit and multiple-visit conventional endodontic therapy. Although the single-visit patients seemed to experience more discomfort than did the multiple-visit patients after the first postobturation day, the differences were not statistically significant. When the total number of pain days was considered, there were no significant differences between the two groups. Thus, single-visit endodontic therapy appears at least equal in desirability to multiple-visit therapy from the point of view of painfulness to the patient.
开展了一项临床研究，以比较单次就诊和多次就诊的传统牙髓治疗术后疼痛的发生率和严重程度。尽管在根管充填后的第一天，单次就诊的患者似乎比多次就诊的患者经历了更多的不适，但差异无统计学意义。当考虑疼痛天数的总数时，两组之间没有显著差异。因此，从对患者造成疼痛的角度来看，单次就诊的牙髓治疗在可取性方面似乎至少与多次就诊治疗相当。
