Study summary

Removal of impacted lower third molar teeth is one of the most common oral surgical procedures, and these operations often lead to various complications in patients. Antibiotics, analgesics and/or anti-inflammatory drugs are prescribed for the treatment of complications encountered. Anti-inflammatory is the property of a substance or treatment that reduces inflammation or swelling. Anti-inflammatory drugs make up about half of analgesics, remedying pain by reducing inflammation as opposed to opioids, which affect the central nervous system to block pain signaling to the brain. Based on this information, in this study, it is aimed to evaluate the effects of deflazacort preoperatively on the postoperative pain, swelling and trismus.

Study arms

  • Experimental
    Deflazacort

    Deflazacort is a glucocorticoid used as an anti-inflammatory drug. We used deflazacort 30 mg tablet. Patient took a pill once preoperatively (1 hour ago) in third molar surgery.

    Drug: Deflazacort 30 MG Oral Tablet

  • Placebo comparator
    Sugar pill

    Placebo is an inert substance or treatment which is designed to have no therapeutic value. Patients took sugar pill for plasebo once one hour before operation.

    Drug: Sugar pill

Interventions

  • After the taken a deflazacort pill once preoperatively (one hour ago), local anesthesia was obtained using 2 ml articaine hydrochloride 40 mg/ml with epinephrine 0.01 mg/ml . The horizontal incision was made with no. 15 scalpel blade and a full thickness mucoperiosteal flap was raised. In all surgical procedures, bone removal and/or tooth sectioning were performed under sterile saline irrigation. Following the extraction, granulation tissues were removed, and bleeding was controlled. Finally, the mucoperiosteal flap was repositioned by 3.0 silk sutures.

What researchers measure

Primary outcomes

  1. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 1st day

  2. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 2nd day

  3. Postoperative Edema

    Postoperative edema was evaluated by the distance between predetermined facial anatomic landmarks (from the mandibular angle to lateral corner of the eye, base of the nose, labial commissura, and soft tissue pogonion) which was measured with using thread and millimeter ruler.

    Time frame: Postoperative 2nd day

  4. Postoperative Trismus

    Postoperative trismus was evaluated by the maximum distance between the incisive borders of the upper and lower right incisive teeth which was measured with a caliper.

    Time frame: Postoperative 2nd day

  5. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 3d day

  6. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 4th day

  7. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 5th day

  8. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 6th day

  9. Postoperative Pain

    Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

    Time frame: Postoperative 7th day

  10. Postoperative Edema

    Postoperative edema was evaluated by the distance between predetermined facial anatomic landmarks (from the mandibular angle to lateral corner of the eye, base of the nose, labial commissura, and soft tissue pogonion) which was measured with using thread and millimeter ruler.

    Time frame: Postoperative 7th day

  11. Postoperative Trismus

    Postoperative trismus was evaluated by the maximum distance between the incisive borders of the upper and lower right incisive teeth which was measured with a caliper.

    Time frame: Postoperative 7th day

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2018 (actual). Primary completion is estimated for Nov 2023, 59 months after the start.

Of 280 non-industry phase 4 interventional studies under Pain, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 35. This study's planned 59 months is above that.

Counting every sponsor, half of 295 studies reached it within 18 months; a quarter within 8 and three quarters within 33.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 22, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
