BACKGROUND
To investigate and compare the post-obturation pain after one-visit and two-visit root canal treatment in non-vital anterior teeth.
MATERIALS & METHODS: One hundred forty eight patients requiring root canal therapy on permanent anterior non-vital teeth with single root were included in this study. Patients were randomly assigned to either the one-appointment or the twoappointment group. The standardized protocol for all the teeth involved local anesthesia, isolation and access, engine-driven rotary nickel-titanium canal instrumentation with 2.5% NaOCl irrigation and obturation. Teeth in group 1 (n = 74) were obturated during the first appointment by using laterally condensed gutta-percha and resin sealer. Teeth in group 2 (n = 74) were given closed dressing and were obturated during the second appointment, 7 to 14 days later. A modified Visual Analogue Scale was used to measure pain after 6 hours, 24 hours, 48 hours and 7 days after the treatment. Statistical analysis was done to compare groups at each interval by using an independent-samples t test.
RESULTS
The incidence and intensity of post-obturation pain in both Group 'A' and Group 'B' gradually reduced over the study period. When the incidence of pain was compared in the single and two visit group, it was found that the single-visit group experienced slightly less pain than the two-visit group during all study intervals, but the difference found was not statistically significant.
CONCLUSION
There was no difference in postoperative pain between patients treated in only one appointment and patients treated in two appointments. The majority of patients in both groups reported no pain or only minimal pain after 7 days of treatment. How to cite the article: Rao KN, Kandaswamy R, Umashetty G, Rathore VP, Hotkar C, Patil BS.

背景
探讨并比较一次性和两次性根管治疗非活髓前牙后的根管充填后疼痛情况。
材料与方法
本研究纳入148例需要对单根恒前牙进行根管治疗的患者。患者被随机分为一次性就诊组或两次性就诊组。所有牙齿的标准化治疗方案包括局部麻醉、隔离与开髓、使用2.5%次氯酸钠冲洗并配合机用旋转镍钛器械进行根管预备及根管充填。第1组（n = 74）的牙齿在首次就诊时采用侧向加压热牙胶和树脂封闭剂进行充填。第2组（n = 74）的牙齿进行暂封，在7至14天后的第二次就诊时进行充填。采用改良视觉模拟量表在治疗后6小时、24小时、48小时和7天测量疼痛情况。使用独立样本t检验对各时间间隔的两组进行统计学分析比较。
结果
在研究期间，“A”组和“B”组根管充填后疼痛的发生率和强度均逐渐降低。比较一次性就诊组和两次性就诊组的疼痛发生率时发现，在所有研究时间段内，一次性就诊组的疼痛略少于两次性就诊组，但差异无统计学意义。
结论
一次性就诊治疗的患者与两次性就诊治疗的患者术后疼痛无差异。两组中的大多数患者在治疗7天后报告无疼痛或仅有轻微疼痛。如何引用本文：Rao KN, Kandaswamy R, Umashetty G, Rathore VP, Hotkar C, Patil BS. 坏死前牙一次性和两次性根管治疗后的根管充填后疼痛。《国际口腔健康杂志》2014；6(2):28 - 32。
