Abstract

AIMS AND OBJECTIVES: Compare the difference in the mean trismus by giving two doses of Dexamethasone after surgical extraction of impacted mandibular third molar.

DURATION: February 2016 to August 2016.

SETTINGS: Out patient Maxillofacial Surgery Department, Madinah Teaching Hospital, Faisalabad.

MATERIAL & METHODS: In this Randomized Clinical Trial, 60 patients divided into 2 groups 30 in each group admitted for removal of unilateral impacted mandibular third molars were included. The age range was 20-50 years for both gender, mouth opening was >35 mm. Group A received 4mg Dexamethasone tablet one hour before the procedure. Group B received 8mg Dexamethasone tablet one hour before the procedure. After proper elevation and reflection of the appropriate muco-periosteal flap, buccal and distal guttering was done in order to facilitate the delivery of tooth. Later, flap was sutured. The outcome variables of both treatment modalities in term of difference in postoperative trismus at day 2 were measured by the ruler and mouth opening less than 35mm was considered as trismus.

RESULTS: In this study, out of 60 patients, 51.7% were males while 48.3% were females. Mean age of the patients was 37.25 + 9.04 years. In Group-A , mean for maximum inter-incisor mouth opening before treatment was 39.20 + 4.23 mm while it was 25.77 + 3.58 mm after treatment. In group B patients who received 8 mg dexamethasone before tooth extraction mean maximum inter- incisor distance before treatment was 38.50 + 4.47 mm. Mean inter-incisor distance after 8mg dexamethasone followed by tooth extraction was 35.53 + 5.11, p-value was found to be < 0.0001 which was clinically significant.

CONCLUSION: 8 mg of dexamethasone was statistically more significant in reduction of trismus as compare to 4mg.
