Effectiveness of pre-operative oral corticosteroids in reducing pain, trismus and oedema following lower third molar extractions: a systematic review
MetadataShow full item record
Aim: To determine if a single pre-operative dose of oral corticosteroids would be effective in reducing pain, trismus and oedema following lower third molar surgical extraction. Secondary outcomes of interest were post-operative complications such as infections. Methods: Searching was conducted using Embase, MEDLINE, DOSS, CINAHL and CENTRAL for randomised controlled trials. Four studies which compared pre-operative oral corticosteroids to placebo prior to lower third molar surgical extractions were eligible for inclusion. Results: All studies were judged to be at unclear risk of bias. All studies tested the efficacy of 8mg dexamethasone 60-90 minutes prior to surgical extractions. Whilst three studies showed improvement in pain visual analogue scale (VAS) scores in the dexamethasone groups, two were not statistically significant. One study found no improvement in pain scores on VAS. One study found no difference in either trismus or oedema. One study reported one occurrence of post-operative alveolar infection in the dexamethasone group and one occurrence of alveolar osteitis in the placebo group. Conclusion: While there seems to be an improvement in pain scores on VAS, these results are not clinically significant. Post-operative analgesia plays a more important role clinically.
