Comparative evaluation of postoperative pain and periapical healing after root canal treatment using three different endodontic sealers: A randomized controlled clinical trial.

Aims: A randomized controlled clinical trial to evaluate postoperative pain and investigate periapical healing after root canal treatment using eugenol, resin-based, and calcium silicate-based sealers (CSBSs) sealers.

Materials And Methods: Sixty-three individuals diagnosed with apical periodontitis confirmed using cold test and electronic pulp tester, periapical pathology with periapical index score of 2 or more, previous endodontic treatment failure exhibiting a visual analog scale pain score of 3 or above, were enrolled in this investigation. The patients were randomly allocated into three groups and following biomechanical preparation, the canals were obturated using Meta CeraSeal, AH plus, and eugenol-based sealers. Postprocedural pain intensity was assessed at 24 h, 48 h, and 7 days, while periapical healing was evaluated at 3- and 6-month follow-ups. Statistical analysis was done using the Chi-square and Friedman's test.

Results: The mean of periapical lesions for Meta CeraSeal (4.7, 1.6), AH Plus (4.68, 3.19), 24 and eugenol-based (2.66, 1.75) at 3 months and 6 months, respectively. The mean & std. deviation of pain scores at 24 h for Meta CeraSeal (0.62 ± 1.857), AH Plus (1.62 ± 1.962), and eugenol-based (0.48 ± 1.250). At 48 h for Meta CeraSeal (0.33 ± 1.528), AH Plus (1.33 ± 1.798). On the 7 day, Meta CeraSeal (0.24 ± 1.091) and AH Plus (0.71 ± 1.384) for eugenol-based at 48 h, and on the 7 day, none of the patients had pain. Evaluation of the apical sealer puff displayed no suggestive variations ( = 0.634). Notably, no analgesics were taken.

Conclusions: No suggestive dissimilarity was noted between eugenol, resin-based, and CSBSs sealers.
