impacted third molars, minimizing these postoperative complications is the center of many studies, one proposed
method is the prophylactic administration of corticosteroids, the aim of this study is to evaluate the effect of
prophylactic Dexamethasone administration on facial swelling and trismus after surgical extraction of impacted third
molars.
Materials and methods: 20 patients were included in this study, they were randomly divided into 2 groups of 10
patients each; a study group in which patients were given 8 mg. Dexamethasone 1 hour before surgical extraction
of impacted third molar and 4 mg. 6 hours postoperatively, and a control group in which no drug was given, mouth
opening and direct facial measurments were done preoperatively and 2 days postoperatively, data were collected
and analyzed.
Results: The study group showed less facial swelling and trismus postoperatively, in facial swelling the difference was
statistically significant, while for trismus the difference was not significant.
