title: Available web-based teaching resources for health care professionals on screening for oral cancer.
abstract: OBJECTIVE
  To identify websites with adequate information on oral cancer screening for healthcare professionals (HCPs) and to assess both their quality and contents.
  
  
  METHODS
  Websites were identified using Google and HON medical professional search engines using the terms "screening for oral cancer". The first 100 sites retrieved by each engine were analysed using the DISCERN questionnaire (reliability), the V instrument (contents on oral cancer) and further by the Flesch-Kinkaid Reading Grade Level and the Flesch Reading Ease (readability).
  
  
  RESULTS
  The overall rating showed minimal shortcomings in the quality of the information in the websites. The coverage and correctness of information on "visual examination" was rated as fair/good, whereas updating of contents resulted very variable (eg: 81% for visual examination and 18.2% for molecular biomarkers). These results permitted to rank the websites housing relevant information for oral cancer. Top ranking websites were affiliated to the Oral Cancer Foundation (USA), WHO Collaborating Centre for oral cancer (UK) whose webpage is entitled "Oral Cancer Education and Research", and the Clinical Guidelines maintained by the British Columbia Cancer Agency (Canada) and the British Dental Association (UK) respectively.
  
  
  CONCLUSIONS
  There are web-based, HCP-addressed, resources on screening for oral cancer housing heterogeneous information both in quality and contents. The use of specific evaluation tools permits the selection of reliable websites on this topic with a potential to improve the existing educational gaps among HCPs.
