Title In the Primary Care Setting, the Value of Adjunctive Aids for Oral Cancer Examinations Remains Unanswered
Clinical Question Should clinicians use oral cancer adjunctive aids for earlier detection of oral cancer?
Clinical Bottom Line Systematic reviews revealed that there is no evidence to support the use of adjunctive aids for the screening of pre-malignant or malignant oral lesions in a general practice setting. Tissue biopsy remains the gold standard for diagnosis. (See Comments on the CAT below)

Key resultsInsufficient evidence to support or refute the use of visually based examination adjuncts.
#2) 12907211Patton/2003Community based oral cancer screening programs 1966-2002: 36 articlesSystematic Review
Key resultsInsufficient evidence to demonstrate the effectiveness of community-based oral cancer visual screening in enhancing the early detection of oral cancer, due to small effect size.
#3) 21069680Brocklehurst,/2010One RTCSystematic review
Key resultsNo statistical difference in mortality rates was found for the overall population studied when screened, however, a statistically significant higher mortality rate was found by screening of high risk tobacco and or alcohol using persons.

Comments on
The Evidence
Both systematic reviews describe a detailed search of relevant articles, and both expressed concern about the lack of high quality definitive research. After Brockelhurst’s analysis of 1,719 studies, only one met the inclusion criteria. The one nine-year RCT reviewed consisted of 191,873 patients and had a high risk of bias.
Applicability At the present time, disciplined visual examination remains the standard for screening for pre-malignant or malignant oral lesions in the primary care setting.

I conducted a PubMed search on this topic in April 2012 and found a more recent publication supporting your CAT. PubMed ID 20436098 is a meta-analysis done in 2010 supporting that visual examination is still the primary diagnostic tool used and more research is needed on adjunctive aids.
