Comparison of two different rotary instruments(Ra Ce, Pro Taper) on postoperetive pain in teeth with asymptomatic irreversible pulpitis

Abstract

Postoperative pain is one of the most common complications after root canal treatment. Root canal debridement techniques might result in postoperative pain. Two of the most commonly used rotary systems in root canal treatment are RaCe and ProTaper rotary systems. The aim of the present study was to compare the effect of two different rotary instruments on postoperative pain in teeth with asymptomatic irreversible pulpitis. Materials and Methods: A total of 78 mandibular first and second molars were divided into two groups (n=39) based on root canal preparation with RaCe or ProTaper rotary system. All the subjects underwent one-visit root canal treatment and postoperative pain severity was evaluated using visual analog scale (VAS) at 4-, 12-, 24-, 48- and 72-hour and 1-week intervals. In addition, taking analgesics was recorded. Data were analyzed with repeated-measures ANOVA and Mann-Whitney U test. Statistical significance was set at P<0.05. Results: Comparison of mean pain severity between the two groups at various postoperative intervals did not reveal any significant differences between the two groups (P=0.10). The difference in analgesics taken between two groups was not significant statistically (P=0.25). Conclusion: There were no significant differences in the relief of postoperative pain between the two groups, indicating the clinical acceptability of both techniques.
