Abstract : The purpose of this study was to investigate whether two types of root canal sealer affect the onset of postoperative pain after root canal filling.

 At Kyushu Dental University Hospital, seven dentists performed infected root canal treatments for 60 patients with periapical lesion. In the root canal filling, non-eugenol root canal sealer was used for 30 patients (non-eugenol group), and 4-META-containing resin-based root canal sealer for the other 30 (resin group). The choice of sealer was randomized. After the root canal filling, the rate and factors of postoperative pain were analyzed.

 As a result, postoperative pain was observed in a few cases in both groups, and no significant difference in the rate of postoperative pain was found between the two groups. Two weeks after the root canal filling, postoperative pain had disappeared in almost all cases, except one case of the non-eugenol group. Gender, age and type of tooth seemed to affect the frequency of postoperative pain, although there was no significant difference between the groups.

 These results suggest that the two root canal sealers examined in the present study may not affect the onset of postoperative pain.
