criteria were randomized to each irrigant, 65 in the NaOCl and 60 in the NSS groups. ProRoot® MTA was used as a pulp dressing material in both groups and teeth were followed for 12 months. The primary outcome was the success of VPT; requiring both clinical and radiographic success to be considered as success. The hypothesis was that the absolute difference of VPT success in the NSS group was not worse than that in the NaOCl group, by a margin of 5%. The secondary outcome was discoloration; percentages of discolorations between both groups were compared. Results: Using a per protocol analysis, the absolute difference of VPT success between the NSS and NaOCl groups was 2.08% (95% CI: -1.95, 6.1). Perceptible gray discolorations were 80% and 63% in NaOCl and NSS groups (difference -17%; 95% CI: -40.0, 6.2; p=0.15). Conclusions: For MTA-VPT procedure, irrigation with NSS was not worse than that with NaOCl. However, both irrigants caused discoloration. (EEJ-2023-05-065).
标准被随机分配到每个冲洗液组，65 个在次氯酸钠组，60 个在生理盐水组。两组均使用 ProRoot® MTA 作为牙髓覆盖材料，随访 12 个月。主要结局为 VPT 成功率；需要临床和影像学成功均被认为是成功。假设是生理盐水组的 VPT 成功率的绝对差异不比次氯酸钠组差，差值为 5%。次要结局为变色；比较两组之间的变色百分比。结果：使用方案分析，生理盐水组和次氯酸钠组之间 VPT 成功率的绝对差异为 2.08%（95%CI：-1.95，6.1）。次氯酸钠组和生理盐水组的可察觉灰色变色分别为 80%和 63%（差异-17%；95%CI：-40.0，6.2；p=0.15）。结论：对于 MTA-VPT 程序，生理盐水冲洗并不比次氯酸钠差。然而，两种冲洗液都会导致变色。（EEJ-2023-05-065）。
