In order to facilitate effective tobacco cessation services within dental school clinics, it is necessary to understand the perceived barriers encountered by dental students while providing these services. The aim of this study was to identify which factors fourth year dental students perceive to be associated with barriers to providing tobacco intervention services. A written survey was developed and completed by the incoming fourth year dental students at the University of Iowa College of Dentistry in 2008. The survey assessed the perceived barriers to providing tobacco intervention services and related factors. Descriptive, bivariate and logistic regression analyses were conducted. The response rate was 97 percent. Some of the most frequently reported barriers included: patient's resistance to tobacco intervention services (96%), inadequate time available for tobacco intervention services (96%) and forgetting to give tobacco intervention advice (91%). The following variables were significantly (p<0.05) related to greater perceived barriers in providing tobacco intervention services: lower "adequacy of tobacco intervention curriculum coverage of specific topics covered over the previous three years" and "perceived importance of incorporating objective structured clinical examination teaching method for learning tobacco intervention." Students could benefit from additional didactic training and enhanced clinical experience in order to facilitate effective intervention services in the dental school.
