This research analyzed the dentists' perceptions and evaluations of anti-smoking campaign processes through dentists' advice(including dental nurses' advice) and the campaign's effects. Although smoking is closely related to dental health, dentists are not active to communicate anti-smoking messages. That is, despite the fact that medical professionals equipped with rich medical knowledge can effectively disseminate health messages, including anti-smoking messages, this kind of effort was not made very often. This study is based on in-depth interviews of dentists and dental nurses in seven dental clinics in Chocho Gu, Seoul, who participated in the anti-smoking advice campaign in 2007. Grounded in an intercultural campaign approach in health communication, this work explored how the dentists and dental nurses perceived the campaign's processes and effects. Following research findings, the dentists and dental nurses perceive that the anti-smoking advice campaign through medical professionals is effective. Also, they recognize that anti-smoking advice using various anti-smoking communication tools is more effective and that the development and dissemination of culturally sensitive anti-smoking messages considering age and gender characteristics is needed. Based on the dentists' and dental nurses' evaluations and perceptions of the anti-smoking campaign, it is essential to develop much more effective anti-smoking campaign tools using medical professionals.
