Fixed regimen analgesic use compared with regimen if needed for pain after gum surgery: a randomized controlled trial

INTERVENTION: Drug Open‐label, randomized controlled trial on demand acetaminophen prescription. Patients in need of clinical crown augmentation were included in the study. After surgery, the patient was allocated to the test group or control group. The test group (34 participants) was prescribed paracetamol (500mg) in a fixed regimen every 4 hours for 48 hours to control postoperative pain. In case the pain did not pass within 1 hour after acetaminophen consumption, the patient was instructed to consume ibuprofen (600mg), with minimum intervals of 6 hours between doses. The control group (34 participants) received paracetamol (500mg) in case of pain, with minimum intervals of 4 hours for 48 hours to control postoperative pain. In case the pain did not pass within 1 hour after acetaminophen consumption, the patient was instructed to consume ibuprofen (600mg), with minimum intervals of 6 hours between doses.
