Efficacy of on-demand versus scheduled postoperative pain medication in endodontic patients with symptomatic apical periodontitis: A Randomized Controlled Trial.

INTRODUCTION

Effective postoperative pain control is essential in endodontics, particularly for emergency patients with symptomatic apical periodontitis (SAP), who are at higher risk for significant discomfort following treatment. While the combination of ibuprofen and acetaminophen is widely used, limited evidence exists comparing scheduled versus on-demand dosing to combat postoperative pain in this population.

METHODS

172 healthy patients presenting to the graduate endodontic clinic for emergency treatment of a painful tooth diagnosed with SAP were initially enrolled in the study. One hundred and twenty-six 126 patients (58 assigned to scheduled dosing and 68 assigned to on-demand dosing) completed and returned postoperative diaries and pills documenting pain levels and medication intake for 3 days post-treatment. Mean pain levels and medication usage were analyzed using linear affects models.

RESULTS

Patients in the scheduled dosing group consumed significantly more medication (P<0.05), with no statistically significant difference in pain scores compared to the on-demand group.

CONCLUSIONS

Patients assigned to the scheduled dosing regimen consumed approximately twice as much medication as those instructed to medicate on-demand (i.e., as needed). Despite this increased medication use, the level of pain relief was not significantly different between the two groups. On-demand dosing of ibuprofen and acetaminophen appears sufficient to manage postoperative pain in patients with symptomatic apical periodontitis, potentially reducing medication use and associated side effects. These findings support a patient-centered analgesic strategy, emphasizing safety, autonomy, and effective symptom management.
