Tooth impaction is a pathological situation in which a tooth cannot or will not erupt into its normal functioning position. Patients usually seek treatment because of symptoms or prophylactically to prevent such symptoms as pain, pericoronitis, caries and the sequalae. Post-operative pain, swelling and trismus are some of the acute and reversible inflammatory complications of M3 surgery. This study was aimed to compare the effects of submucosal dexamethasone and intramuscular dexamethasone on pain, swelling and trismus following M3 surgery. Two cohorts were recruited for the study A and B, consisting of 44 and 40 participants respectively. Group A was given submucosal dexamethasone and group B was given intramuscular dexamethasone. Biodata, pain, mouth opening and extent of facial swelling were data of interest. There was an even distribution of the study population, by age and gender. There was statistically significant difference (p<0.05) in post-operative pain reduction on post-operative days 1 and 3 for submucosal dexamethasone treated cohort, compared to the intramuscular dexamethasone treated cohort. There was also a statistically significant difference (p<0.05) in mouth opening on post-operative days 1, 3 and 7 for submucosal dexamethasone treated cohort, compared to the intramuscular dexamethasone treated cohort. This study concludes that post-operative symptoms were improved by both agents and that submucosal dexamethasone compared to intramuscular dexamethasone showed statistically significant reduction in limitation of mouth opening and swelling. The workers therefore recommend that submucosal dexamethasone be administered near the operation site pre-operatively before incision for M3 surgery.
