NCT04059172 · Status: RECRUITING · Phase: EARLY_PHASE1 · Type: INTERVENTIONAL · Enrollment: 375
Last updated 2026-05-14
Summary
The purpose of this study is to compare the effectiveness of a combined ibuprofen and acetaminophen regimen in controlling discomfort for 4 days after initial orthodontic appliance placement as compared to ibuprofen alone or a placebo. The hypothesis is that combined ibuprofen and acetaminophen therapy will effectively provide better pain control than ibuprofen alone or a placebo after orthodontic appliance placement.
