Effect of Calcium-Based Bioceramic Sealer and Resin-Based Sealer on Postoperative Pain

Overview

This study aims to compare the effect of calcium-based bioceramic sealer and resin-based sealer on postoperative pain in adult patients with asymptomatic apical periodontitis undergoing root canal treatment. Asymptomatic apical periodontitis is a condition where the tissue around the tip of the tooth root is inflamed or shows a lesion on X-ray, but the patient does not experience pain. A total of 60 patients will be randomly assigned to receive root canal treatment with either the bioceramic sealer (Group A) or the resin-based sealer (Group B). Pain after treatment will be measured using a 0-10 Numeric Pain Rating Scale at 4, 24, and 48 hours post-treatment. The highest pain score reported will determine whether the treatment is considered a success (no or mild/moderate pain) or failure (severe pain). The results of this study will provide evidence on which sealer is associated with less postoperative pain, helping clinicians make informed decisions about root canal filling materials.

This randomized controlled clinical trial aims to compare calcium-based bioceramic sealer and resin-based sealer in root canal treatment for adult patients with asymptomatic apical periodontitis. Asymptomatic apical periodontitis is a condition where the tissue around the tip of the tooth root is inflamed or shows a lesion on X-ray, but the patient does not feel pain. A total of 60 patients aged 18-55 years will be recruited at the Department of Operative Dentistry, Fatima Memorial Hospital, Lahore. Eligible patients will have non-vital teeth with fully formed roots and periapical lesions classified as PAI scores 2-4. Patients with systemic diseases, periodontally compromised teeth, or complications during treatment will be excluded. Patients will be randomly assigned to two groups: Group A will receive root canal obturation using bioceramic sealer, and Group B will receive resin-based sealer. The treatment procedure involves standard root canal cleaning and shaping, irrigation, and obturation using a single-cone technique with Gutta-percha. Postoperative pain will be assessed using a Numeric Pain Rating Scale (0-10) at 4, 24, and 48 hours after obturation. The highest pain score reported across these time points will determine the outcome. Pain levels will be classified as: None (0), Mild (1-3), Moderate (4-7), or Severe (8-10). Patients with severe pain (8-10) will be considered treatment failures, while all others will be considered treatment successes. Data will be analyzed using SPSS. Descriptive statistics will summarize demographic and clinical variables, and Chi-square tests will compare postoperative pain between groups. The study aims to provide evidence on which sealer results in less postoperative pain, supporting better clinical decision-making in endodontics.
