Background:
Post-operative pain (PP) following pulpectomy is of concern for endodontic patients and dentists.
Aim:
This study evaluated the intensity of PP following pulpectomy in primary maxillary molars, using two irrigation needles.
Design:
One hundred patients in ages ranging from 6-9 years requiring pulpectomy for asymptomatic primary teeth with non-vital pulp were included in the study. The participants were randomly assigned to two groups of 50 patients each, according to the type of irrigation needle used, that is, a conventional open-ended needle and a double side-vented needle. The teeth were obturated and then permanently restored. The presence of PP was assessed after six, 12, 24, 48, and 72 hours, and finally after one week, using a four-point pain intensity scale. The PP scores were then statistically analysed.
Results:
In 6, 12, and 24 hours time intervals, patients who had their teeth irrigated with the open-ended needle exhibited more intense PP than those who had their teeth irrigated with a double side-vented needle (P < .05). After 48 hours, 72 hours, and 1 week, however there was no significant difference between the groups (P > .05).
Conclusions:
Side-vented needles may be preferred in order to decrease PP at the first 24 hours after pulpectomy in primary molars.
