Tobacco-related health problems are the most preventable forms of illness in the United States. By assuming proactive tobacco use cessation counseling roles, dentists and dental hygienists can help reduce the number of people who currently use tobacco. The literature reports that many oral health professionals feel unprepared to assume such roles. To help combat the problem of tobacco-related illness and to help prepare dentists and dental hygienists to assume tobacco use cessation counseling roles, dental schools and dental hygiene programs need to develop appropriate didactic and clinical tobacco use cessation curriculum content. To date, there are limited national data addressing the extent of tobacco use cessation education in dental schools and dental hygiene programs. Studies of medical schools have revealed a need for increased curriculum content on tobacco use prevention and cessation. Further, tobacco use cessation training programs for medical students, practicing dentists, and dental hygienists have resulted in increased student and provider confidence when tobacco use cessation counseling roles were assumed. This study surveyed all dental schools and dental hygiene programs in the U.S. to determine if tobacco-related curriculum content exists, and if so, to what extent. Variables addressed included allocated hours, subject content, scope, department responsible, workplace smoking policy, importance, and future curricular directions. Questionnaires were mailed to all dental hygiene program directors and dental school academic deans. Study findings suggest that dental and dental hygiene students receive limited tobacco use cessation education, and respondent schools have no immediate plans for curriculum change in this area.(ABSTRACT TRUNCATED AT 250 WORDS)
