Details of the systematic review undertaken for this guideline

The initial literature search was carried out in May 1997 and was updated during the course of the guideline development.

The MEDLINE database from 1966 was searched for evidence-based literature. This identified 119 papers. The EMBASE database from 1974 was searched for evidence-based English language papers relating to human subjects. This identified 313 results.

The evidence-based search criteria included research or evidence-based guidelines, meta-analyses, systematic reviews or overviews, literature or academic reviews, randomised controlled trials or studies, placebos, random allocation, triple, double or single blind method or masks or procedure, clinical trials, specifically excluding letters, historical articles, reviews of reported cases or multicase reviews or studies.

The search was limited by subject to impacted, unerupted, asymptomatic third or 3rd molar or molars or wisdom tooth or teeth.

In addition a general subject search of the MEDLINE database for English language papers relating to human subjects from1985 identified 738 citations.

The general subject search for impacted, unerupted, asymptomatic third or 3rd molar or molars or wisdom tooth or teeth, but not limited to the evidence-based criteria listed above, covered mainly specific subject areas.
