The present investigation recorded the 2-year clinical and radiographic outcome of one- and two visit endodontic treatment and studied the significance of the bacteriologic sampling results on the outcome. A randomization procedure allocated 53 teeth to one-visit treatment and 48 teeth to two-visit treatment. At the end of the study period, 32 teeth (65%) in the one-visit group and 30 teeth (75%) in the two-visit group were classified as healed. The statistical analysis of the healing results did not show any significant difference between the groups (p = 0.75). Forty-nine (80%) of the 61 teeth that were obturated after a negative micobiologic sample were classified as healed. Teeth sealed after positive samples healed in 44%. The present study gave evidence that similar healing results might be obtained through one- and two-visit antimicrobial treatment.
本研究记录了一次就诊和两次就诊根管治疗的2年临床及影像学结果，并研究了细菌学取样结果对治疗结果的意义。随机程序将53颗牙齿分配至一次就诊治疗组，48颗牙齿分配至两次就诊治疗组。在研究期末，一次就诊组的32颗牙齿（65%）和两次就诊组的30颗牙齿（75%）被归类为愈合。愈合结果的统计分析未显示两组之间有任何显著差异（p = 0.75）。61颗微生物样本为阴性后进行充填的牙齿中有49颗（80%）被归类为愈合。微生物样本为阳性后进行充填的牙齿愈合率为44%。本研究证明，通过一次就诊和两次就诊的抗菌治疗可能获得相似的愈合结果。
