Abstract: Alleviation of pain during endodontic procedure can be achieved using intracanal medications with combinations. Aim: This study aims to compare the pain-relieving effectiveness of calcium hydroxide (CH) when combined with normal saline, lidocaine, and dexamethasone. Methods and material: 45 patients diagnosed with irreversible pulpitis and symptomatic apical periodontitis in mandibular molars having pain score greater than 50 on visual analogue scale (VAS) of 100 mm were included. After preparing the root canals, the patients were randomly assigned to one of three groups with the help of scientific random number table. (n=15 in each group): Group A: CH mixed with saline, Group B: CH with lidocaine Hydrochloride and Group C: CH mixed with saline. Postoperative spontaneous pain levels were recorded daily for one week using the VAS. Statistical analysis was performed using one-way ANOVA, chi-squared test, and Mann-Whitney U tests, with a significance level set at p = 0.05. Results: Calcium hydroxide with lidocaine HCl experienced significantly less pain compared to the other groups during the first three days (p < 0> 0.05). Conclusion: The combination of calcium hydroxide and lidocaine may be an effective combination for alleviating pain during root canal treatment.
