Introduction: The basic idea of a root canal treatment is to alleviate the pain and heal the infection within the infected tooth, which can be resolved in a single visit or multiple visits in root canal therapy. Therefore, in this article, an in vivo comparison of single visits and multiple visits using different rotation and speed for two Protaper universal design file systems is done on the basis of time taken and incidence of pain. Materials and Methods: One hundred single-rooted premolars with irreversible symptomatic pulpitis were assigned to two groups of 50 patients each using the odd–even method, GA to be treated endodontically in a single visit and GB to be treated endodontically in multiple visits. Each group was further divided into two subgroups of 25 patients each on the basis of two different variations of speed and rotation for two Protaper file systems of the same design, GA1 (Hand Protapers) and GA2 (Rotary Protapers), GB1 (Hand Protapers) and GB2 (Rotary Protapers), respectively. After proper biomechanical shaping and cleaning, obturation was done with Gutta-percha cones and Ah plus sealer using Fast Pack obturation pen for warm vertical compaction. The pain was measured by a 100mm modified visual analogue scale, and time was measured using a stopwatch. Results: At 6-h intervals, post-obturation pain was more in single-visit root canal therapy than multiple-visit root canal therapy (P < 0.01). Single-visit rotary Protaper (GA2) had less incidence of post-obturation pain as compared with single-visit hand protapers (GA1) (P < 0.05). There was no significant difference in post-obturation pain in the multiple-visit hand protaper subgroup (GB1) and multiple-visit rotary protaper subgroup (GB2) (P > 0.05). Preoperative pain significantly influences the post-obturation pain. The statistical analysis was done using SPSS (Statistical Package for Social Sciences) version 17.0 statistical Analysis Software. Conclusions: The presence of preoperative pain can significantly influence the presence of postoperative pain. Most of the pain in both single-visit and multiple-visits root canal therapy occurred in the first 48 h after obturation, which decreases thereafter. Single-visit rotary protaper (GA2) had less incidence of post-obturation pain as compared with single-visit hand protapers (GA1). There was no significant difference in post-obturation pain in the multiple-visit hand protaper subgroup (GB1) and multiple-visit rotary protaper subgroup (GB2). Presence of sealer puff influences the duration of pain.
