Abstract
The proponents of local route of Dexamethasone (DXM) administration for impacted mandibular 3rd molar (MM3) surgeries claim advantages over the traditional systemic routes. This systematic review and meta-analysis were aimed to determine whether the route of perioperative administration of DXM influences the inflammatory outcomes of MM3 surgeries. An electronic database search over a 25year period of randomised trials of DXM in MM3 surgeries was conducted. The mean differences or standardised mean differences were extracted and pooled using the fixed or random-effects model. Of the sixteen selected trials, four were considered for a meta-analysis. There were no statistically significant differences in the inflammatory outcomes between the local and systemic routes of DXM. The claimed advantages of the local route of DXM do not appear to be scientifically valid. Clinical trials supported with DXM plasma measurements are needed to confirm the absence of a systemic effect when DXM is administered locally.
