The purpose of this study was to analyze students' perceptions of comfort and anticipated willingness to treat selected special needs and traditionally underserved populations immediately upon completion of community-based clinical assignments. The sample consisted of University of Iowa senior dental students who completed a questionnaire that asked, in part, about student comfort with and future willingness to treat twelve vulnerable population groups. With student comfort and future willingness to treat each group as dependent variables, logistic models were developed to determine whether there were significant associations between dependent variables and gender, graduation year, and students' prior experience with these groups. Regression models indicate students' prior experience is most often associated with comfort in treating the associated population group. Likewise, experience and comfort add different dimensions to perceived future willingness to treat almost all of the twelve groups. Student gender, graduation year from dental school, and community assignments influence only a few of these targeted population groups. This study provides empirical evidence concerning students' perceptions about comfort with various vulnerable populations after completing their extramural rotations. Students were more comfortable treating certain population groups as well as more willing to consider including these groups in their future practices.

The purpose of this project was to determine new dentists' comfort levels in treating traditionally underserved populations after participating in two consecutive five-week community-based clinical experiences while in dental school. A written survey was mailed to all known University of Iowa alumni (1992-2002; N=745). Respondents were asked to rank their comfort levels in treating twelve underserved populations on a five-point Likert type scale (5=no problem; 1=will not). Bivariate and logistic regression model analyses were performed to examine associations (p<0.05) among comfort and six predictor variables. Alumni (n=372) were most comfortable treating other ethnic, low-income, non-English-speaking, and HIV+/AIDS populations and least comfortable treating incarcerated and homebound populations. The following variables were significantly associated with comfort: 1) perception that the community experiences had great/much value; 2) practice located in larger communities; 3) non-solo practitioners; and 4) dentist's gender. As more dental schools utilize community-based clinical experiences to increase students' exposure to underserved populations, it is important that these experiences provide exposure to a variety of populations. Additionally, dental schools should continuously monitor the short-and long-term value of these programs for their students and recent graduates.

This study analyzed senior dental students' perceptions prior to extramural rotations for comfort and future willingness to treat patients with special needs and other vulnerable groups. The sample included 690 University of Iowa senior dental students who graduated from 1992 through 2004. These students completed a questionnaire concerning twelve vulnerable population groups. Logistic regression models were performed, using student comfort and future willingness to treat each group as the dependent variable. There was a wide percentage of range of comfort with these groups, yet there was no individual group that more than 60 percent of these students were willing to treat in their future practices. Generally, prior experience with the group had a positive impact on comfort level. When gender was included in the regression models, male students were more likely to express comfort. In all instances except one, experience had a positive influence on perceived future willingness to treat the associated group. However, younger graduates had a greater willingness to treat. When controlling for other variables within the future willingness to treat models, comfort was statistically significant only for HIV+/AIDS and non-English speaking groups. This study provides insight about comfort with and perceived future willingness to treat special needs and other vulnerable patient groups.
