title: Maryland dental hygienists' knowledge and opinions of oral cancer risk factors and diagnostic procedures.
abstract: OBJECTIVE
  To examine Maryland dental hygienists' (DHs) knowledge of oral cancer risk factors and diagnostic procedures, as well as opinions about the currency and adequacy of their oral cancer knowledge, educational preparation, interest in, and preferred types of, continuing education courses.
  
  
  METHODS
  Seven hundred DHs were randomly selected from a registry of 2677 Maryland licensed dental hygienists. A mailed survey instrument provided baseline data on 331 (RR = 60%) DHs. Stratified tabular and logistic analytical techniques were employed (alpha level < or =0.05).
  
  
  RESULTS
  Most correctly identified tobacco use (99.7%) and alcohol use (89%) as risk factors; however, 31% incorrectly identified poor oral hygiene as a risk factor. 64% of DHs correctly identified older age as a risk factor, yet only 16% identified that the majority of oral cancers are diagnosed in the 60+ year old age group. Nearly 91% correctly identified the examination procedures of the tongue for oral cancer detection; while only 16% of DHs correctly identified erythroplakia and leukoplakia as the conditions most likely associated with oral cancer.
  
  
  CONCLUSIONS
  Gaps in knowledge exist and strongly suggest the need for continuing education courses to clarify risk factors and diagnostic procedures associated with earlier oral cancer detection and prevention.
