ORIGINAL PROF-0-4618 Sajjad Ali Darvesh 1 , Irum Naz 2 , Abdul Razzaq Ahmed 3 , Farhan Butt 4 , Wasey Latif 5 , Azam Shahzad 6 ABSTRACT… Objective: To compare post obturation endodontic fare-ups following single and multiple visit root canal treatment. Study Design: Quasi experimental study. Setting Operative dentistry department, DOW university hospital Karachi. Period: 2 nd October 2017 to 2 nd April 2018. Material & Methods: A total of 100 patients of permanent exposed anterior teeth with positive pup response / vital, either gender were included. Patients divided into two groups according to single and multiple visit root canal treatment. At each post obturation recall visit the patients were interviewed and inspected to determine whether or not there are symptoms. Results: A total of 100 patients came for root canal treatment. At 1st post obturation day, out of 50 patients treated in one visit, four experienced a fare-up (8%). Out of 50 patients treated in two visits, eight experienced a fare-up (16%) (P-value=0.12). At 3rd post obturation day, out of 50 patients treated in one visit, three experienced a fare-up (6%). Out of 50 patients treated in two visits, fve experienced a fare-up (10%) (P-value=0.37). Conclusion: We conclude that almost same results for single and multiple visit endodontics were achieved not statistically signifcant. Key words: Flare-ups, Working Length, Working Width. 1.

DOI: 10.29309/TPMJ/2020.27.07.4618 INTRODUCTION The ongoing ferce battle over one visit versus multiple endodontic treatments has become a very clouded issue that is debated not with scholarly precision but with business minded intent. 1 In today’s fast moving world, patients are requesting for treatment modalities that requiring minimum visits. 2 This has created interest in clinicians to study the advisability and effcacy of root canal therapy in one visit total endodontic care of a tooth in a single visit is an old concept in clinical practice. 3 Modern root canal treatment has grown rapidly over the last few years as more and more people are willing to salvage their teeth. Advances in technology, instruments and chemical composition have led to the most comprehensive and satisfying procedures for the treatment of root canals today. 4 Problems associated with the root canal treatment are postoperative pain, during visiting pain and infammation. Such cases usually do not last long, but they can embarrass the dentist and bother the patient, especially if the tooth was symptom less before the commencement of treatment. 5 Postoperative pain associated with canal therapy is a bad indicator of long-term success, but the occurrence and management of pain are of interest to the health of endodontics. 6 Certain factors such as preoperative pain, number of appointments use of intracranal medications and tooth localization may predispose the development of postoperative pain and fare- ups. Some authors reported slightly more post- obturation pain following single visit than with multiple visit procedures. Others found no signifcant differences in the post-obturation pain experienced by patients following single or multiple visit treatment procedures. 7 The natural beneft of multiple visit treatments is DOI: 10.29309/TPMJ/2020.27.07.4618
