Dental students' perceptions of standardized patient experiences using Zoom: Dyadic factors

PURPOSE

The COVID-19 pandemic required a rapid transition to online education, including simulations. The current study identified students' perceptions of communicating with standardized patients in a virtual setting.

METHODS

This qualitative study thematically analyzed 485 reflections submitted by 248 students between Spring 2020 and Spring 2022. Statements describing both the virtual medium and dyadic interactions between students and patients were coded for emergent themes and also coded as positive (facilitative) or negative (critical).

RESULTS

Four themes emerged from the data related to the virtual medium: impact on nonverbal communication, patient engagement/rapport, presentation aids, and listening. Within these broad themes, 13 subthemes were identified, nine of which were negative/critical. Technology problems were specifically identified as compromising both engagement and listening. Even when technology worked well, students noted that it reduced the number of message cues received from the patient and complicated the process of sending cues (e.g., by requiring students to look away from a patient's face to make "eye contact" through a camera).

CONCLUSIONS

Overall, students were critical of Zoom's impact on dyadic factors with standardized patients. However, they did acknowledge some positive aspects regarding the technology. These findings provide a foundation to consider when teaching students how to communicate effectively via teledentistry.

The interactive effects of oral health literacy and acculturation on dental care use among Hispanic adults

Objective

Assess whether there is an interactive effect between oral health literacy and acculturation on dental care use for Hispanic adults.

Methods

Self‐identifying Hispanic adults participated in this observational study (N = 338). Oral health literacy (low vs. high) was measured using the Comprehensive Measure of Oral Health Knowledge (CMOHK). Acculturation (low vs. high) was measured using the Short Acculturation Scale for Hispanics (SASH) and operationalized a second way by the language in which the survey was completed (English or Spanish). The outcome was dental care use in the past year (yes/no). Confounder‐adjusted modified Poisson regression models were run to generate risk ratios (RR) and to test the hypothesis that participants with high oral health literacy and high acculturation would be more likely to have used dental care in the past year than participants with low oral health literacy and low acculturation.

Results

About 65% of participants used dental care in the past year. The final models failed to show that participants with high oral health literacy and high acculturation were more likely to have used dental care than other participants. However, in the language proxy interaction model, participants with high oral health literacy and low acculturation were significantly more likely to have used dental care than participants with low oral health literacy and low acculturation.

Conclusion

There may be an interaction between oral health literacy and acculturation when modeling dental care use for Hispanic adults that should be further explored.

Repair versus replacement of defective direct restorations: A cross-sectional study among US dentists

BACKGROUND

Repair increases the longevity of restorations and is well-accepted by patients. In this study, the authors assessed the acceptance of dental restoration repair by dentists and determined the main variables of repair versus replacement of defective restorations.

METHODS

A 15-item questionnaire was developed and distributed electronically to the American Dental Association Clinical Evaluators panel members (n = 785) during a 2-week period in 2019. Descriptive, bivariate, and multivariable analyses were conducted.

RESULTS

Of the 387 respondents, 83.7% stated that they repair defective restorations, and 16% stated that they always replace them. Reasons to forego a restoration repair among dentists who perform repairs included defect size and carious lesion extension (42%) and negative personal experience or lack of success (37.9%). However, the latter was considerably higher for dentists who do not perform repairs (60.7%). The most commonly cited patient-related reason and tooth condition to repair restorations were limited patient finances (67%) and noncarious marginal defects (86%), respectively. Neither sex nor age group was significantly associated with the practice of restoration repair (P = .925 and P = .369, respectively). However, sole proprietors were more likely to perform repairs than those in an employee, associate, or contractor practice setting (P = .008). The most significant reason to forego restoration was negative experience or lack of success (P = .002).

CONCLUSIONS

Restoration repair is considered a treatment option for managing defective restorations. Negative personal experience or lack of success and practice setting influenced the dentists' decision to repair or replace a defective restoration.

PRACTICAL IMPLICATIONS

Understanding dentists' clinical challenges and practice environment is necessary when advocating for this approach.

An evaluation of the geriatric dental curricula within Advanced Education in General Dentistry and General Practice Residency programs in the United States

AIM

To compare the geriatric dentistry curricula between Advanced Education in General Dentistry (AEGD) and General Practice Residency (GPR) programs.

METHODS

A 108-item survey was developed to assess residents' didactic and clinical experiences pertaining to geriatric patients. Surveys were mailed in 2018 to all AEGD (N = 89) and GPR (N = 180) program directors. Statistical analysis consisted of descriptive and bivariate analyses with the chi-square test, Fisher's exact test, and the Wilcoxon rank sum test (alpha = .05).

RESULTS

Twenty-four AEGD and fifty-eight GPR directors completed surveys (response rate = 30%). Seventy-one percent of responding programs reported mandatory didactic training pertaining to frail and functionally dependent geriatric adults. Ninety-nine percent of respondents reported that residents provided treatment to geriatric patients; however, they were less likely to perform procedures on frail and functionally dependent patients. Only 15% of respondents provided nursing home care. Considering all patient encounters, responding GPR programs were more likely than AEGD programs to treat patients using IV bisphosphonates (63% vs 25%; P < .01), undergoing chemotherapy (48% vs 16%; P = .02), and undergoing head and neck radiation therapy (55% vs 25%; P = .02).

CONCLUSION

A majority of responding AEGD and GPR programs reported providing educational experiences pertaining to geriatric patients; however, GPR programs reported treating more medically complex patients than AEGD programs.

Prescribing practices for antibiotic prophylaxis in patients with prosthetic joints

AIMS

With the increasing number of patients with prosthetic joints, recommendations for antibiotic prophylaxis (AP) prior to dental procedures to prevent prosthetic joint infections (PJI) have changed.

METHODS AND RESULTS

This survey evaluated dentists' AP practices for patients with prosthetic joints undergoing dental procedures and their familiarity with the American Dental Association Guidelines (ADA CPG) and American Academy of Orthopaedic Surgeons Appropriate Use Criteria (AAOS AUC). Dentists' attitudes about antibiotic resistance, medical-legal aspects, and adverse effects to using AP were examined. Dentists (n = 574) were familiar (51.2%) with ADA CPG and with the AAOS AUC (25.8%). Familiarity varied according to years since graduation. Female dentists (63.5%) were more likely to be very familiar with the ADA CPG than male dentists (49.5%). Overall, 65.4% of respondents believed that AP is not effective in the prevention of PJI, and 19.4% believed there is enough evidence to support AP. For a healthy patient, 28.9% of dentists would never recommend AP, 44.9% would recommend AP within the first two years since prosthetic joint replacement.

CONCLUSIONS

Dentists' recommendations for the use of AP varied depending on different factors, including health status of the patient, dental procedure, time elapsed since joint surgery, suggesting that adherence to the ADA CPG and AUC is still challenging.

Oral health knowledge levels of Hispanics in Iowa

BACKGROUND

Hispanics disproportionately experience preventable oral health conditions in the United States. This study aimed to determine the oral health knowledge (OHK) of Hispanic adults in Iowa to identify potential gaps in knowledge.

METHODS

This cross-sectional study included a convenience sample of self-identifying Hispanic adults. Data pertaining to oral health literacy and demographic, cultural, and dental characteristics were collected. OHK was assessed with the Conceptual Measure of Oral Health Knowledge, and it was categorized as low or high. Bivariate analyses and multiple logistic regression models were conducted to identify the variables related to OHK (P < .05). Institutional review board approval was obtained.

RESULTS

Three hundred thirty-eight participants completed the questionnaire, 68% of participants completed the questionnaire in Spanish, and 51% of all participants had low OHK. Participants were less likely to correctly answer questions pertaining to children's oral health, periodontal disease, and oral cancer. Low OHK was associated with having less than 12th grade education, lack of dental insurance, and preference for a Spanish-speaking oral health care provider.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

OHK appears to be low in this population. Increasing OHK may help decrease oral health disparities and improve oral health outcomes. Furthermore, it is important that oral health care providers have an understanding of barriers that can impede patients' understanding of the health care system. Specifically, minority populations, such as Hispanics, may have a harder time because of certain cultural differences that exist among this ethnic group.

Preferences Related to the Use of Mobile Apps as Dental Patient Educational Aids: A Pilot Study

PURPOSE

Numerous patient education apps have been developed to explain dental treatment. The purpose of this study was to assess perceptions and preferences regarding the use of apps in dental settings.

MATERIALS AND METHODS

Four patient education apps describing fixed partial dentures were demonstrated to participants (N = 25). Questions about each app were asked using a semi-structured interview format to assess participants' opinions about each app's content, images, features, and use. Sessions were analyzed via note-based methods for thematic coding.

RESULTS

Participants believed that apps should be used in conjunction with a dentist's explanation about a procedure. They desired an app that could be tailored for scope of content. Participants favored esthetic images of teeth that did not show structural anatomy, such as tooth roots, and preferred interactive features.

CONCLUSIONS

Patient education apps may be a valuable tool to enhance patient-provider communication in dental settings. Participants exhibited varying preferences for different features among the apps and expressed the desire for an app that could be personalized to each patient. Additional research is needed to assess whether the use of apps improves oral health literacy and informed consent among patients.

Should PGY-1 Be Mandatory in Dental Education? Two Viewpoints: Viewpoint 1: PGY-1 Provides Benefits That Support Making It Mandatory and Viewpoint 2: PGY-1 Should Be Available for Dental Graduates But Not Mandatory

This Point/Counterpoint considers whether a general dentistry postgraduate year one (PGY-1) residency should be required for all new graduates who do not pursue specialty training. Currently, New York and Delaware require PGY-1 for dental licensure, while other states offer it as an alternative to a clinical examination for obtaining licensure. Viewpoint 1 supports the position that PGY-1 should be mandatory by presenting evidence that PGY-1 residencies fulfill new graduates' need for additional clinical training, enhance their professionalism and practice management skills, and improve access to care. The authors also discuss two barriers-the limited number of postdoctoral positions and the high cost-and suggest ways to overcome them. In contrast, Viewpoint 2 opposes mandatory PGY-1 training. While these authors consider the same core concepts as Viewpoint 1 (education and access to care), they present alternative methods for addressing perceived educational shortcomings in predoctoral curricula. They also examine the competing needs of underserved populations and residents and the resulting impact on access to care, and they discuss the potential conflict of interest associated with asking PGY-1 program directors to assess their residents' competence for licensure.

Changes in Dental Students' Attitudes About Treating Underserved Populations: A Longitudinal Study

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.

An Exploration of Dental Students' Assumptions About Community-Based Clinical Experiences

The aim of this study was to ascertain which assumptions dental students recalled feeling prior to beginning community-based clinical experiences and whether those assumptions were fulfilled or challenged. All fourth-year students at the University of Iowa College of Dentistry & Dental Clinics participate in community-based clinical experiences. At the completion of their rotations, they write a guided reflection paper detailing the assumptions they had prior to beginning their rotations and assessing the accuracy of their assumptions. For this qualitative descriptive study, the 218 papers from three classes (2011-13) were analyzed for common themes. The results showed that the students had a variety of assumptions about their rotations. They were apprehensive about working with challenging patients, performing procedures for which they had minimal experience, and working too slowly. In contrast, they looked forward to improving their clinical and patient management skills and knowledge. Other assumptions involved the site (e.g., the equipment/facility would be outdated; protocols/procedures would be similar to the dental school's). Upon reflection, students reported experiences that both fulfilled and challenged their assumptions. Some continued to feel apprehensive about treating certain patient populations, while others found it easier than anticipated. Students were able to treat multiple patients per day, which led to increased speed and patient management skills. However, some reported challenges with time management. Similarly, students were surprised to discover some clinics were new/updated although some had limited instruments and materials. Based on this study's findings about students' recalled assumptions and reflective experiences, educators should consider assessing and addressing their students' assumptions prior to beginning community-based dental education experiences.

Service-learning's impact on dental students' attitude towards community service

BACKGROUND

This study evaluated service-learning programme's impact on senior dental students' attitude towards community service at Virginia Commonwealth University (VCU) School of Dentistry. Experience gained through service-learning in dental school may positively impact dental students' attitude towards 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 of 105 responded and reported their attitude towards community service immediately after the service-learning programme completion. Three weeks later, 56 students of the 76 responded to the second survey (retrospective pre-test) and reported their recalled attitude prior to the programme 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 behaviour, benefits, career benefits and intention showed a significant pre-test and post-test difference. An association between attitude towards 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 programme at VCU School of Dentistry has positively impacted senior dental students' attitude towards community service.

Neighborhood and family social capital and parent-reported oral health of children in Iowa

OBJECTIVES

A growing body of evidence supports the impact of social factors on oral health disparities in children in the United States. The goal of this study was to examine the relationship between two types of social capital-family and neighborhood-and the parent-reported oral health of Iowa's children.

METHODS

We analyzed results from a 2010 cross-sectional statewide health survey. The outcome was parent-reported child oral health status, and the five primary independent variables were neighborhood social capital and four separate indicators of family social capital. Data were analyzed using a mixed-effects linear regression with a random effect for zip code.

RESULTS

Significant positive associations were found between child oral health status and neighborhood social capital (P = 0.005) and one indicator of family social capital, family frequency of eating meals together (P = 0.02), after adjusting for covariates.

CONCLUSIONS

This study adds to the growing body of literature around the social determinants of oral health. Our findings indicate that the oral health of children may be influenced by broad social factors such as neighborhood and family social capital.

Oral health knowledge among elderly patients

BACKGROUND

The purpose of this study was to determine the level of oral health knowledge among patients 65 years or older to identify areas in which knowledge gaps exist.

METHODS

The authors administered the Comprehensive Measure of Oral Health Knowledge questionnaire to patients 65 years or older at a university-based dental clinic and examined associations between oral health knowledge scores and participants' demographic and dental characteristics.

RESULTS

Most participants were familiar with basic dental disease prevention and treatment; however, many participants were unfamiliar with concepts pertaining to periodontal disease, oral cancer, and children's oral health.

CONCLUSIONS

Advocates for geriatric oral health should educate elderly populations about the risk factors associated with periodontal disease and oral cancer, especially as they become more at risk of experiencing these diseases.

PRACTICAL IMPLICATIONS

Educational messages aimed at both routine and nonroutine users of dental care should be developed on the basis of universal health literacy principles to facilitate understanding among elderly adults, who have varying literacy levels.

Association of community-based dental education components with fourth-year dental students' clinical performance

The purpose of this study was to assess which components of a community-based dental education (CBDE) program at The University of Iowa College of Dentistry & Dental Clinics were associated with overall student performance. This retrospective study analyzed data for 444 fourth-year students who graduated in 2006 through 2011. Information pertaining to students' CBDE rotations and their final grades from the comprehensive clinic (in two areas: Production and Competence) were used for statistical analysis. Bivariate analyses indicated that students who completed CBDE in the fall were more likely to receive an A or B in Production compared to students who completed CBDE in the spring. However, students who completed CBDE in the beginning or end of the academic year were more likely to receive an A or B in Competence compared to those who completed CBDE in the middle of the year. Students who treated a variety of patient types during CBDE experiences (comprehensive and emergency care vs. mainly comprehensive care) were more likely to receive better grades in Production, while CBDE clinic type was not associated with grades. Dental schools should consider how CBDE may impact students' performance in their institutional clinics when developing and evaluating CBDE programs.

Association between dentists' participation in charitable care and community-based dental education

The Institute of Medicine and the Commission on Dental Accreditation (CODA) have recommended that dental schools incorporate community-based dental education (CBDE) programs into their curricula. The expectation is that CBDE participation will help dental students gain the skills and motivation to treat vulnerable populations after graduation. The purpose of this study was to determine whether dentists' involvement with charitable dental care is associated with participation in CBDE as dental students. A questionnaire was mailed to private practice Iowa dentists (N=1,312); the response rate was 41.2 percent (n=541). Logistic regression analyses, controlling for age, gender, number of hours worked per week, graduation year, and alma mater, were conducted. A majority of the respondents provided charitable care: 85 percent in their offices, and 70 percent in the community. Seventy-nine percent had participated in CBDE as dental students. Respondents who reported being very satisfied/satisfied with their charitable care experiences were more likely to provide charitable care in their offices and the community than respondents who were not satisfied with their experiences. Respondents who participated in CBDE as dental students were more likely to provide charitable care in the community than respondents who did not participate in CBDE. The type of sites where dentists completed their CBDE experiences was associated with where they provide charitable care. This study suggests that participation in CBDE may be associated with dental students' providing charitable dental care after graduation.

Influence of minor children and contribution to household income on work hours of female dentists

OBJECTIVE

To study the association of having minor children and contribution to household income on weekly work hours of Iowa female dentists.

METHODS

A 28-question survey was mailed to all active Iowa dentists. This study represents female dentists who responded to the survey (n = 192; response rate = 63 percent). The dependent variable was whether dentists currently worked full- or part-time (≥ 32 versus <32 hours/week). The associations of having minor children and the percent women contributed toward their household income were then analyzed using stepwise logistic regression, controlling for covariates (alpha = 0.05).

RESULTS

Of the respondents, 14.6 percent worked part-time. Females who had no minor children (40.1 percent) were 3.1 times as likely to work full-time (P = 0.0353), and those who contributed >60 percent to household income (57.8 percent) were 3.0 times as likely to work full-time (P = 0.0129). The final regression model indicated that those who contributed >60 percent to household income (P = 0.0096) and had no leave of absence longer than 45 consecutive days within the prior 2 years (P = 0.0483) were more likely to work full-time compared with their counterparts.

CONCLUSION

Iowa female dentists who provided more than 60 percent to household income and had not taken a leave of absence during the past 2 years were more likely to work full-time. The inclusion of leave of absence as a predictor variable negates any additional influence of the presence or absence of minor children in the regression model, indicating that these variables are highly correlated for this population.

Geographic accessibility and utilization of orthodontic services among Medicaid children and adolescents

OBJECTIVES

To describe rates of Medicaid-funded services provided by orthodontists in Iowa to children and adolescents, identify factors associated with utilization, and describe geographic barriers to care.

METHODS

We analyzed enrollment and claims data from the Iowa Medicaid program for a 3-year period, January 2008 through December 2010. Descriptive, bivariate, and multivariable logistic regression analyses were performed with utilization of orthodontic services as the main outcome variable. Service areas were identified by small area analysis in order to examine regional variability in utilization.

RESULTS

The overall rate of orthodontic utilization was 3.1 percent. Medicaid enrollees living in small towns and rural areas were more likely to utilize orthodontic services than those living in urban areas. Children who had an oral evaluation by a primary care provider in the year prior to the study period were more likely to receive orthodontic services. Service areas with lower population density and greater mean travel distance to participating orthodontists had higher utilization rates than smaller, more densely populated areas.

CONCLUSIONS

Rural residency and increased travel distances do not appear to act as barriers to orthodontic care for this population. The wide variability of utilization rates seen across service areas may be related to workforce supply in the form of orthodontists who accept Medicaid-insured patients. Referrals to orthodontists from primary care dentists may improve access to specialty care for Medicaid enrollees.

Significant indicators of intent to leave among Army Dental Corps junior officers

OBJECTIVE

To identify the significant predictors associated with Army Dental Corps junior officers' intent to leave (ITL) the military.

METHODS

A secondary data analysis of the 2009 Army Dental Officer Retention Survey was conducted. Frequencies, bivariate, linear, and logistic regression analyses were calculated.

RESULTS

Forty-six percent of junior officers completed the survey (N = 577; n = 267). Fifty-eight percent of respondents reported an ITL the military before retirement. The following variables were positively associated (p < 0.05) with ITL: unit of assignment, specialty training status or area of concentration, military lifestyle, and residency training. Age and benefits were negatively associated with ITL.

CONCLUSION

This study suggests that ITL is a multifactorial issue.

A model for overview of student learning: a matrix of educational outcomes versus methodologies

A concise overview of an institution's aspirations for its students becomes increasingly elusive because dental education has evolving emphases on priorities like critical thinking and adapting to new technology. The purpose of this article is to offer a learner-oriented matrix that gives a focus for discussion and an overview of an institution's educational outcomes. On one axis of the matrix, common educational outcomes are listed: knowledge, technical skills, critical thinking, ethical and professional values, patient and practice management, and social responsibility awareness. On the other axis, methodologies are listed: definition, cultivation strategies, measures (summative/formative, objective/subjective), institutional coordination, and competency determination. By completing the matrix, an overview of the process by which students reach these outcomes emerges. Each institution would likely complete the matrix differently and, ideally, with active discussion. While the matrix can first be used to establish "Where are we now?" for an institution, it can also be a starting point for more extensive matrices and further discussion. Vertical and horizontal analyses of the matrix provide a unique lens for viewing the institution's learning environment.

Dental students' perceived comfort and future willingness to treat underserved populations: surveys prior to and immediately after extramural experiences

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.

Fourth-year dental students' perceived barriers to providing tobacco intervention services

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 incoming fourth-year dental students (a convenience sample of seventy 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 linear regression analyses were conducted. The response rate was 97 percent. The most frequently reported barriers were patients' resistance to tobacco intervention services (96 percent), inadequate time available for tobacco intervention services (96 percent), and forgetting to give tobacco intervention advice (91 percent). 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 greater "perceived importance of incorporating objective structured clinical examination teaching method for learning tobacco intervention." Students probably could benefit from additional didactic training, but most important may be enhanced clinical experiences and faculty reinforcement to facilitate effective practical student learning and adaptation for future delivery of intervention services in private practice settings.

Dentists' comfort in treating underserved populations after participating in community-based clinical experiences as a student

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.

Students' opinions about treating vulnerable populations immediately after completing community-based clinical experiences

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.

General dentists' referrals of 3- to 5-year-old children to pediatric dentists

BACKGROUND

Little is known about general dentists' referral patterns. The authors explored the practice, dentist and patient characteristics associated with general dentists' likelihood of referring children aged 3 to 5 years to pediatric dentists.

METHODS

The authors sent all Iowa general dentists (N = 1,089) a 25-item questionnaire regarding the referral of children in their practices. The authors merged the resulting information with an existing database (Iowa Dentist Tracking System) to create the dataset. A total of 65.4 percent of the dentists (712) participated.

RESULTS

Logistic regression analysis demonstrated that an increase in the percentage of children in the practice decreased the likelihood of the dentist's referring the children (odds ratio [OR] = 0.93, 95 percent confidence interval [CI] = 0.90 to 0.96). Practices with more than 5 percent of patients with public insurance were more likely to refer children (OR = 1.96, 95 percent CI = 1.26 to 3.06), as were dentists with additional training beyond dental school (OR = 1.69, 95 percent CI = 1.06 to 2.69).

CONCLUSION

These data indicate that both practice and dentist characteristics are associated with the likelihood of making referals; however, there needs to be further study on general dentists' referral decisions.

PRACTICE IMPLICATIONS

As the characteristics of the dental work force evolve, there is a need to study referral patterns and the influence they have on work force policy, patient accessibility and educational curriculum.

Students' comfort level in treating vulnerable populations and future willingness to treat: results prior to extramural participation

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.

General dentists' referral of children younger than age 3 to pediatric dentists

PURPOSE

The purpose of this study was to assess which variables are associated with Iowa general dentists' referral of children younger than age 3 to pediatric dentists.

METHODS

A survey was mailed to all Iowa general dentists (N=1,089). Respondents were asked how likely (never, sometimes, often, always) they were to refer children younger than age 3 to pediatric dentists in the past 12 months. Associations between referral patterns with practice, dentists,' and patients' characteristics were determined.

RESULTS

The adjusted response rate was 65%. Nearly 50% of all dentists reported often or always referring children younger than age 3. Dentists who referred were more likely to be males and to have been in practice longer. Dentists who perceived that they had not received adequate exposure to preschool children younger than age 3 in dental school were more likely to refer. Dentists with smaller percentages of children within their practices were more likely to refer. Dentists most often referred children who were uncooperative, had severe decay, or had special needs.

CONCLUSIONS

About one half of Iowa's general dentists refer children younger than age 3 to a pediatric dentist. Initiatives need to be undertaken to address dentists' reluctance to care for young children.
