Comparison of Frequency of Calcium Hydroxide Mixed With 0.2% Chlorhexidine Versus Saline as Intracanal Medicament in Periapical Periodontitis-A Randomized Controlled Trial

This randomized controlled trial aims to compare the effectiveness of calcium hydroxide mixed with 0.2% chlorhexidine digluconate versus calcium hydroxide mixed with saline as intracanal medicaments in reducing postoperative pain in patients with apical periodontitis. A total of 80 adult patients with anterior teeth diagnosed with apical periodontitis will be randomly assigned to two equal groups. After standard chemomechanical root canal preparation, Group A will receive calcium hydroxide with saline, while Group B will receive calcium hydroxide with 0.2% chlorhexidine. Postoperative pain will be assessed using a 10-point Visual Analogue Scale (VAS) at 12, 24, and 48 hours. The primary outcome is the frequency and severity of pain at 24 hours. Data will be analyzed using chi-square or Fisher's exact test, with a significance level of p \< 0.05. The study aims to determine whether the addition of chlorhexidine improves the analgesic and antimicrobial effectiveness of calcium hydroxide during root canal treatment.
