ABSTRACT
Objectives: To assess the incidence of postoperative pain after single- and multi-visit
endodontic treatment of teeth with vital and non-vital pulp.
Methods: In total, 306 patients with teeth requiring endodontic treatment were identified
and were included in this study. Two experienced clinicians treated the patients,
who were randomly assigned to two groups. While the teeth of patients in group 1 were
obturated, group 2 were temporarily sealed and obturated after one week. Three days
after the root canal instrumentation of each tooth, the patients were asked whether
they experienced any postoperative pain and to rate the level of discomfort as no,
mild, moderate, or severe pain. Data were analyzed statistically using the chisquare
test.
Results: No significant difference in postoperative pain was found between vital and
non-vital teeth (P>.01). Mild, moderate, and severe pain occurred in 31.4, 13.7, and
4.6% of vital teeth, respectively. Postoperative pain occurred in 107 (69.9%) and
106 (69.3%) teeth in the single- and multi-visit treatment groups, respectively. There
was no significant difference in postoperative pain between the two groups (P>.01).
Conclusions: The prevalence of postoperative pain did not differ between vital and
non-vital teeth. The majority of patients in either groups reported no or only mild
pain. (Eur J Dent 2009;3:273-279)
