OUTCOME ASSESSMENT
pain
EVENT
All the required records, such as orthopantomograms (OPGs), intraoral periapical
radiographs (IOPARs), and probing depths for maxillary canines, were taken prior
to retraction (T0) and after 5 months (T5). Questionnaires for pain assessment
were given to each patient to complete at home and return on the next
appointment. Patients were discouraged from taking painkillers and when they
did, in the event of severe pain, they were advised to write it down. Patients
were recalled at intervals of 21 days for 5 months (T1-T5). Measurements were
made on dental casts according to the procedure described in a previous
study
