Postoperative Pain After Root Canal Treatment Using Different Root Canal Sealers

This prospective randomized clinical trial aims to compare the effects of three different root canal sealers-AH Plus, ProRoot Bio Sealer, and BC Sealer ion+-on postoperative pain following root canal treatment in patients diagnosed with asymptomatic irreversible pulpitis. Postoperative pain is a common complication after endodontic treatment and may be influenced by microbial, chemical, and mechanical factors. The type and composition of root canal sealer may also affect tissue response, inflammation, and pain levels. AH Plus is an epoxy resin-based sealer known for its sealing ability and dimensional stability, whereas ProRoot Bio Sealer and BC Sealer ion+ are bioceramic sealers with enhanced bioactive properties. BC Sealer ion+ additionally releases both calcium and magnesium ions, which may improve tissue healing and biological performance. The study will include patients aged 18-60 years presenting with asymptomatic irreversible pulpitis in mandibular first or second molars. Following ethical approval from the European University of Lefke Ethics Committee, approximately 135 patients will be enrolled and randomly assigned into three equal groups according to the root canal sealer used. Sample size calculation was performed using G\*Power software with 80% statistical power and a significance level of 0.05. All treatments will be completed in a single visit by the same experienced clinician under standardized clinical conditions. Root canal preparation will be performed using the ProTaper Universal rotary system with standardized irrigation protocols including sodium hypochlorite, EDTA, chlorhexidine, and sonic activation. Obturation will be completed using a modified single-cone technique with the assigned root canal sealer. Patients and the outcome assessor will be blinded to group allocation. Postoperative pain will be assessed using the Numeric Rating Scale (NRS) at 6, 12, 24, 48, and 72 hours, as well as on day 7 after treatment. Secondary outcomes will include analgesic consumption and flare-up incidence. All patients will be prescribed ibuprofen to use only if necessary, and analgesic intake will be recorded. The primary objective of this study is to determine whether different root canal sealers significantly influence postoperative pain levels after root canal treatment. The null hypothesis states that there will be no statistically significant difference among AH Plus, ProRoot Bio Sealer, and BC Sealer ion+ regarding postoperative pain outcomes. Data will be analyzed using appropriate statistical methods, with a significance level set at P \< 0.05.

Effect of Instrumentation Systems and Sealers on Postoperative Pain

The goal of this randomized clinical trial is to evaluate whether different root canal preparation systems and sealer types affect postoperative pain after root canal treatment in adult patients (18-60 years) with asymptomatic irreversible pulpitis in mandibular premolars. The main questions it aims to answer are: Do different instrumentation systems (TruNatomy vs ProTaper Gold) influence postoperative pain levels? Do different sealer types (AH Plus vs TotalFill BC) affect postoperative pain and analgesic consumption? Researchers will compare TruNatomy and ProTaper Gold systems combined with AH Plus or TotalFill BC sealers to determine their effect on postoperative pain. Participants will: Undergo single-visit root canal treatment using one of the assigned file system and sealer combinations Record their pain levels using a Numerical Rating Scale (NRS) at specific time intervals (6, 12, 24, 48, 72 hours, and 7 days) Take ibuprofen only if needed and record analgesic intake Attend a follow-up visit on the 7th day
