Distinct neural networks for the volitional control of vocal and manual actions in the monkey homologue of Broca's area.

BACKGROUND

This randomized clinical trial evaluated postoperative pain and analgesic intake in patients with pulp necrosis and asymptomatic chronic apical periodontitis.

MATERIAL AND

METHODS

Sixty-three patients were randomly assigned to two groups receiving root canal irrigation with either 2.5% calcium hypochlorite (Ca (OCl)2) or 2.5% sodium hypochlorite (NaOCl). Root canal preparation was performed using rotary instruments, and all canals were filled in a single visit. Postoperative pain was assessed using a 0-10 numerical rating scale at 24, 48, and 72 hours, and one-week post-treatment. Analgesic intake was also recorded. Statistical analysis was performed using Fisher's exact test.

RESULTS

No significant differences in pain levels were observed between groups at 24 hours (p = 0.601) or other time points. Most patients (95.2%) reported no pain, 3.1% mild pain, and 1.5% severe pain. Analgesic intake was reported by only one patient.

CONCLUSIONS

Calcium hypochlorite is a promising irrigant for endodontic treatment, showing comparable postoperative pain outcomes to sodium hypochlorite.
