Tobacco cessation knowledge, attitudes, and behaviors of dentists participating in a large national managed care dental plan were assessed using a mailed survey. The survey was administered to dentists recruited to participate in an evaluation of a CD-ROM and supportive electronic detailing to promote increased tobacco cessation activities. General dentists who met specific technological criteria, had an active E-mail account, and at least 200 adult patients were eligible to participate in this study. A total of 184 dentists, located in 29 states, agreed to participate. The survey instrument included questions that addressed (a) Ask, Advise, Assess, Assist, and Arrange behaviors, (b) self-efficacy including knowledge, confidence, and success regarding tobacco cessation, (c) success of various tobacco cessation strategies, (d) barriers to tobacco cessation, and (e) demographics including year of graduation, gender, and race/ethnicity. Self-reported baseline tobacco intervention-related behaviors were low, with 28% of dentists reporting that they asked their patients about tobacco or recorded tobacco use in their patients' charts at least 41% of the time. For Advise behavior, approximately half of the dentists advised tobacco-using patients to quit at least 41% of the time. Although self-reported lack of knowledge was high, 71% of respondents indicated that their lack of knowledge was either not a barrier or a slight barrier to incorporating tobacco cessation into their practices. The survey revealed that dentists do not routinely incorporate tobacco cessation into their practices. Newer information-transfer technologies may serve as vehicles for increased smoking cessation activities by dentists.

Smokeless tobacco (ST) products sold in the U.S. vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of ST use versus constituent levels in the ST product in exposure of users to carcinogens. In this study, ST users of brands varying in nicotine and TSNA content were recruited from three different regions in the U.S. Participants underwent two assessment sessions. During these sessions, demographic and ST use history information along with urine samples to assess biomarkers of exposure and effect were collected. During the time between data collection, ST users recorded the amount and duration of ST use on a daily basis using their diary cards. Results showed that independent of pattern of ST use and nicotine yields, levels of TSNA in ST products played a significant role in carcinogen exposure levels. Product standards for reducing levels of TSNA in ST products are necessary to decrease exposure to these toxicants and potentially to reduce risk for cancer.

The PES may be a useful tool for the evaluation or oral tobacco products.
