Root Canal Therapy

The main objective of this study is to compare the healing rate of periapical lesions after non-surgical endodontic retreatment in teeth obturated with gutta-percha versus those obturated with mineral trioxide aggregate (MTA), with a 12-month follow-up. Secondary objectives include evaluating differences between groups in healing time, postoperative pain, and tooth discoloration.

This randomized controlled trial aims to compare the incidence of endodontic flare-ups in patients undergoing single-visit versus multiple-visit root canal treatment (RCT) at Saidu College of Dentistry, Swat. The study will recruit 344 patients aged above 10 and below 60 years, with permanent first molars indicated for RCT and meeting specific clinical and radiographic criteria. Participants will be randomly allocated into two groups: one receiving single-visit RCT and the other receiving multiple-visit RCT. Pain and flare-up incidence will be evaluated using the Visual Analog Scale (VAS) and swelling grading criteria at 6, 24, and 48 hours post-treatment. The primary outcome is the frequency of endodontic flare-ups requiring additional intervention. The study also examines the role of occlusal reduction in managing postoperative discomfort. Data will be analyzed using SPSS v23 with chi-square and Fisher's exact tests to compare outcomes. The findings aim to inform evidence-based protocols for endodontic treatment in the local population.
