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).
