SUMMARY REVIEW/ORAL SURGERY
Data sources The Cochrane Oral Health Group’s Trials Register, the
Cochrane Central Register of Controlled Trials (CENTRAL), Medline,
Embase and the metaRegister of Controlled Trials were searched with
no language restrictions.
Study selection Randomised controlled double-blinded clinical trials
using the third molar model were included.
Data extraction and synthesis Two review authors independently
and in duplicate extracted data. The proportion of patients with at
least 50% pain relief (based on total pain relief (TOTPAR) and summed
pain intensity difference (SPID) data) was calculated for all three
drugs at both two and six hours post-dosing and meta-analysed for
comparison.
Results Seven studies involving 2241 patients were included. Two
studies were considered to be at low risk of bias, three at high risk
and two unclear risk of bias. Ibuprofen was found to be a superior
analgesic to paracetamol at several doses, with high quality evidence
suggesting that ibuprofen 400 mg is superior to 1000 mg paracetamol
based on pain relief (estimated from TOTPAR data) and the use of
rescue medication meta-analyses. Risk ratio (RR) for at least 50%
pain relief (based on TOTPAR) at six hours was 1.47 (95% confdence
interval (CI) 1.28 to 1.69; fve trials) favouring 400 mg ibuprofen
over 1000 mg paracetamol, RR for not using rescue medication (also
favouring ibuprofen) was 1.50 (95% CI 1.25 to 1.79; four trials).
For combined drug RR for at least 50% of the maximum pain relief

and ibuprofen 400 mg) (one trial; moderate quality evidence). RR
not using rescue medication 1.60 (95% CI 1.36 to 1.88) (two trials;
moderate quality evidence). Adverse events were comparable between
the treatment groups, but no formal analysis could be undertaken.
Conclusions There is high quality evidence that ibuprofen is superior
to paracetamol at doses of 200 mg to 512 mg and 600 mg to 1000
mg respectively based on pain relief and use of rescue medication data
collected at six hours postoperatively. The majority of this evidence (fve

Commentary
Post-op pain is a concern following any surgical procedure for
patients and health care providers. Third molar extractions are not
an exception. There is concern for appropriate pain management
in this setting. Pain after extraction of third molars is common and
it can impact quality of life for patients for a few days or as long
as a few weeks. Practitioners need to be aware of different means
of managing pain caused by inflammation following surgical
procedures. It is known that anti-inflammatory drugs are the most
useful for treating this type of pain. Paracetamol or narcotics alone
may not have the same effect.
The wide use of narcotics has been a topic for discussion. A recent
survey/study, sent to a small group of oral surgeons in Canada and
the US, reflects that narcotics are still prescribed (hydrocodone and
codeine) after surgical procedures. A small percentage will prescribe
NSAIDs only.

There is a rising trend to decrease the amount of narcotics
prescribed due to the undesirable side effects. This is why this is
a clinically relevant topic as to assessing the use of non-narcotic
analgesics. The review had a specific question which was to find the
best strategy for pain relief following wisdom teeth extraction based
on the nature of this surgical procedure. Pain relief was assessed
at different intervals and doses of ibuprofen, paracetamol and
combinations in one pill.
As a Cochrane review, it was conducted with an appropriate
methodology, only English databases were searched, a thorough
critical appraisal was performed. A grade of the evidence for each
outcome was presented using GRADEprofiler, summarising the
findings, quality of evidence and strength of the recommendations.
The authors’ grading for the individual drugs was considered high
quality, so further research is very unlikely to change the estimate
of effect. This reassures the use of Ibuprofen 400 mg as a lone drug,
with minimal need for redosing at six hours post-op. The outcome
for the combination of ibuprofen 400 mg/paracetamol 1000 mg was
moderate quality indicating that further research is likely to have an
important impact on the authors’ confidence of the effect and may
change the estimate. Overall the majority of adverse events were
minor in nature (GI effects, headaches and dizziness).

evidence emerges and in response to feedback, and the Cochrane

The novel combination drug is showing encouraging results based on
the outcomes from two trials when compared to the single drugs.
