Background: For both the patients and the clinicians, the occurrence of post-treatment pain is undesirable. Pain has an adverse effect on a patient's daily routine. One of the common treatment protocols well accepted in terms of safety and efficacy is multiple sitting root canal therapy. Hence; we undertook the present study to assess the incidence of post- treatment pain in patients undergoing single sitting and multiple sitting root canal therapy. Materials & Methods: The present study included assessment of 200 patients who underwent treatment with root canal therapy. Complete details of the age, gender of all the patients and status of pulp of the involved teeth were also recorded in details. All the teeth were divided broadly into two study groups. First group included single sitting root canal therapy cases while the other group included multiple sitting root canal cases. All the cases were performed by skilled and experienced endodontist. Patients were asked about the post-treatment pain at the starting of the second appointment. Three days after the initial appointment of the patients, the assessment of post operative pain was carried out. Categorization of pain was done as follows: No pain, mild pain, moderate pain, and severe pain. All the results were analyzed by SPSS software. Results: A total of 200 subjects were included in the present study. Out of 200, 106 were males while 94 were females. 73 males and 62 females exhibited post operative pain. 126 subjects out of 185 in which peri-apical lesions were absent showed presence of post-treatment pain. Non-significant results were obtained while comparing pain among patients of the two study groups. Conclusion: There is no difference in the incidence of post-treatment pain in patients undergoing single sitting and multiple sitting root canal therapies.
