To compare the incidence and intensity of post-obturation pain after single or multi visit root canal treatment on single rooted teeth in a randomized controlled trial.
Two hundred patients requiring root canal treatment on permanent single rooted teeth (both vital and non vital) were included. The patients were assigned randomly into two groups of 100 patients each. The teeth in Group1 (n = 100) were obturated at the first visit, whilst those in Group 2 (n = 100) were obturated in a second visit 7 days later. A modified Heft Parker visual analog scale was used to measure pre-operative pain and post-obturation pain at 6, 12, 24 and 48 hours after obturation. Independent-sample T-tests was used for statistical analysis.
Twelve patients were excluded from the study as they failed to follow the scheduled revisit. Data were obtained from the remaining 188 patients. There was no statistically significant difference in the incidence and intensity of post-obturation pain experienced by two groups.
The incidence and intensity of post-obturation pain experience following one- or two-visit root canal treatment on teeth with a single canal were not significantly different.
在一项随机对照试验中，比较单根牙单次或多次就诊根管治疗后根管充填后疼痛的发生率和强度。
纳入200例需要对恒单根牙（活髓和死髓）进行根管治疗的患者。患者被随机分为两组，每组100例。第1组（n = 100）的牙齿在首次就诊时进行充填，而第2组（n = 100）的牙齿在7天后的第二次就诊时进行充填。使用改良的Heft Parker视觉模拟量表测量术前疼痛以及充填后6、12、24和48小时的充填后疼痛。采用独立样本T检验进行统计分析。
12例患者因未按计划复诊而被排除在研究之外。从其余188例患者中获得数据。两组患者充填后疼痛的发生率和强度无统计学显著差异。
单根管牙齿一次或两次就诊根管治疗后充填后疼痛的发生率和强度无显著差异。
