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.

Although respondents reported treating most populations, community leaders and dentists should identify at-risk populations and develop protocols to help ensure that these populations are able to obtain, at a minimum, emergency care. Additionally, dental schools should develop educational curricula to help increase students' comfort in treating underserved populations.

The aim of this study was to assess changes in a group of dental students' feelings about, willingness to treat, and perceived responsibility in treating underserved populations as they progressed through their predoctoral education. A questionnaire was developed to assess the first-through fourth-year (D1-D4) students' attitudes about treating 13 underserved populations after graduation. Surveys were distributed from 2008 to 2014, resulting in longitudinal data from three graduating classes (D1 year: N=240; eligible D4 participants: N=221). A total of 132 students from the three classes (Class of 2012 N=41; 2013 N=46; 2014 N=45; adjusted response rate 60%) completed all surveys (D1-D4). The results showed that changes in students' feelings about treating and willingness to treat underserved populations were population-specific rather than universal. Compared to the D1 year, the students in later years anticipated feeling more negatively towards treating low-income, frail elderly, homebound, homeless, other ethnic groups, and non-English-speaking patients, while their feelings were more positive towards treating known drug users and HIV/AIDS populations. Across the four years, students' willingness to treat low-income, frail elderly, homebound, and non-English-speaking populations after graduation became more negative, while their willingness to treat medically complex populations, known drug users, and HIV/AIDS populations became more positive. The students also became less likely to strongly agree that it is their responsibility as dentists to treat underserved populations as they progressed through school. These respondents reported that clinical and faculty interactions had impacted their likelihood to treat underserved populations. These findings may point to specific types of interventions and faculty mentoring to bring about change.

The purpose of this study was to compare the perceived change in comfort level and future willingness of senior dental students toward treating 12 different groups of traditionally underserved populations. Written surveys of senior dental students were conducted prior to and after completing extramural clinical rotations. A Likert-type scale was used to assess student comfort, whereas future willingness to treat these populations was dichotomous. Over a 13-year period (1992–2004), 560 students completed both surveys. There was an improvement in students’ comfort level for 7 of 12 groups after the community-based assignments, yet there were no differences among population groups based on students’ gender or assignments. There were positive changes for future willingness to treat patients who were mentally compromised, homeless, and non-English speaking, while there was a negative change for treating patients who were frail and elderly and those who were HIV+ or had AIDS. Students with improved comfort levels were more apt to be willing to treat patients who were frail elderly, medically complex, mentally compromised, and non-English speaking in the future. While student comfort in treating several groups improved after completion of the community-based experiences, there were mixed results for future willingness to treat underserved populations.

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.

Introduction This study evaluated service-learning program’s impact on senior dental students’ attitude toward community service at Virginia Commonwealth University (VCU) School of Dentistry. Experience gained through service-learning in dental school may positively impact dental students’ attitude toward community service that will eventually lead into providing care to the underserved. Materials and methods Two surveys (pre and post-test) were administered to 105 senior dental students. For the first survey (post-test), seventy six students out of 105 responded and reported their attitude toward community service immediately after the service-learning program completion. Three weeks later, fifty six students out of the 76 responded to the second survey (retrospective pre-test) and reported their recalled attitude prior to the program retrospectively. Results A repeated-measure mixed-model analysis indicated that overall there was improvement between pre-test and post-test. Scales of connectedness, normative helping behavior, benefits1, career benefits, and intention showed a significant pre-test and post-test difference. An association between attitude toward community service and student characteristics such as age, gender, ethnicity, and volunteer activity was also examined. Only ethnicity showed an overall significant difference. White dental students appear to have a differing perception of the costs of community service. Conclusions The service-learning program at VCU School of Dentistry has positively impacted senior dental students’ attitude toward community service.
