Evaluation of postoperative pain perception incidence after single-visit versus multiple-visit root canal therapy: A randomized controlled trial

Background: Newer concept of root canal therapy is single-visit one rather than conventional multivisit therapy. Major complaint of patients after root canal therapy is mild or severe pain. Aim: This study aims to assess the prevalence of postoperative discomfort after root canal treatment conducted in both single and multiple visits. Materials and Methods: An experiment using a randomized controlled trial design was conducted, including a total of 80 participants. These individuals were then separated into two groups, with each group consisting of 40 participants. Group A had single-visit root canal therapy, whereas Group B received multivisit root canal treatment. The incidence of pain after therapy was evaluated and compared at four time points: 6 hours, 12 hours, 24 hours, and 48 hours after obturation. Results: The level of pain experienced by patients in Group B was notably greater in comparison with individuals in Group A. Nevertheless, there was no statistically significant difference in the level of pain reported by the patients 48 hours after treatment in either of the groups. Conclusion: There is no significant difference in the occurrence of discomfort after endodontic treatment conducted in either a single visit or many visits, as seen during a 48-hour period after obturation.
