Abstract

Aim: This prospective study evaluated the prevalence of postoperative pain with respect to tooth vitality and preoperative pain in patients undergoing conventional root canal treatment. Methodology: A total number of 338 teeth from 317 patients who were to receive conventional root canal treatment from four endodontists during a period of 18 months were considered for this study. Based on the presence or absence of preoperative pain during the initiation of the treatment, the teeth were grouped as either symptomatic (S) or asymptomatic (AS). Based on the presence or absence of haemorrhage during access cavity preparation the teeth were grouped as either vital (V) or non-vital (NV) respectively. The root canals were prepared using ProTaper rotary system and filled using lateral compaction technique. Most of the cases were completed in a single appointment when possible. The patients were recalled 1 week after the obturation for follow-up. At each visit, they were asked to record the postoperative pain since the previous visit as: none, slight, moderate or severe. The data were statistically analyzed using chi-square tests. P level ≤ 0.05 was taken as significant. Results: Forty six teeth were eliminated from the analysis of the results. Of the 292 remaining teeth, 66 fell into the non-vital asymptomatic (NV/AS) group, 60 in non-vital symptomatic (NV/S) group, 39 in vital asymptomatic (V/AS) group and 127 in the vital symptomatic (V/S) group. Out of 292 teeth treated 11 reported severe postoperative pain. Therefore the overall prevalence of flare-up was 3.8%. The prevalence of postoperative pain was least in V/AS group and it was significant when compared to NV/S (P= 0.002) and V/S (P= 0.029). The prevalence of preoperative pain was high in the NV group compared to V group (P= 0.049). The prevalence of postoperative pain was also high in S group compared to the AS group (P= 0.01). Conclusion: Pulp status and preoperative pain can be considered as factors that influence the occurrence of postoperative pain. Patients who present with preoperative pain are at a higher risk of postoperative, particularly when the tooth is non-vital.
