title: Oral cancer: knowledge, practices and opinions of dentists in Ireland.
abstract: OBJECTIVE
  Early detection of oral cancer improves prognosis, but the malignancy is often detected at advanced stages, when more aggressive therapies, often with poor and devastating outcomes for the patient, are needed. Oral cancer can be detected by opportunistic screening of oral mucosa without need of sophisticated equipment. Dentists are important in primary and secondary prevention of oral cancer; therefore, assessing their knowledge, opinions and practices is crucial.
  
  
  METHODS
  A questionnaire survey of dentists was conducted regarding knowledge of risk factors and diagnostic concepts of oral cancer, practices of primary and secondary prevention, and opinions of the effectiveness of formal undergraduate training for early detection and prevention of this disease. The survey explored dentists' potential training needs.
  
  
  RESULTS
  Dentists appear to be generally knowledgeable regarding diagnostic concepts and risk factors. A total of 89% reported providing screening of intra- and extra-oral soft tissue to adult patients (18+) to exclude oral cancer. A total of 27% always provide tobacco use cessation counselling, and 12% provide alcohol moderation/cessation assistance. A total of 54% felt adequately trained to palpate the lymphatic nodes associated with oral cancer. Over half of dentists reported that their knowledge of and training on oral cancer was current; however, 74% reported lack of patient education materials regarding prevention and early detection of oral cancer.
  
  
  CONCLUSIONS
  The survey findings suggest that dentists are underutilised in the prevention and early detection of oral cancer, and one of the barriers is lack of training. Dentists' knowledge and skills must be reinforced and systematically updated by continuing professional education. Greater emphasis should be placed on the fact that dentists have a larger role to play in the prevention and detection of this malignancy at its early, curable stages.
