Developing Dental Students’ Awareness of Health Care Disparities and Desire to Serve Vulnerable Populations Through Service‐Learning

Service-learning in dental education helps students integrate knowledge with practice in an underserved community setting. The aim of this study was to explore how a service-learning experience affected a small group of dental students' beliefs about cultural competence, professionalism, career development, desire to practice in a community service setting, and perceptions about access and disparities issues. Prior to beginning their first year of dental school, five first-year dental students at one U.S. dental school participated in a six-week service-learning program in which they interned at one of three at-risk settings in order to experience health care delivery there. After the program, 60 reflective writing assignments completed by the participants were analyzed using grounded theory methods; interviews with the students were used to corroborate the findings from that analysis. Seven themes identified in the journal reflections and interview findings showed enhanced awareness of social health care issues and patient differences, as well as a social justice orientation and desire to address disparities. Building on this study, future research should explore the curricular components of service-learning programs to ensure students receive ample opportunity to reflect upon their experiences in order to integrate previously held assumptions with their newfound knowledge.

Relationship Between Hand‐Skill Exercises and Other Admissions Criteria and Students’ Performance in Dental School

The aim of this study was to investigate the existence of correlations between dental admissions criteria, including a chalk carving exercise, and students' subsequent academic performance. The retrospective cohort study examined the records of dental students at Louisiana State University Health Science Center School of Dentistry for the years 1998 to 2008. Only those students who could be categorized into the following four groups were included: 1) those who graduated in the top 10% of their class, 2) those who graduated in the bottom 10% of their class, 3) those who repeated a year of dental school, and 4) those who were dismissed or resigned. The study sample consisted of 176 students: 62 in the first group, 62 in the second group, 25 in the third group, and 27 in the fourth group. Data collected were each student's undergraduate grade point average (GPA); chalk carving score; undergraduate biology, chemistry, physics (BCP) GPA; Dental Admission Test (DAT) Academic Average; Perceptual Ability Test (PAT) score of the DAT; total DAT score; grade in preclinical operative dentistry class; grade in morphology and occlusion class; and dental school GPA at graduation. The results showed that only the undergraduate GPA and BCP GPA were significantly higher for students in the top 10% of their class than for other groups. The only positive correlation involving the chalk carving scores was with the preclinical operative dentistry course grade. This study thus found limited correlations between this institution's admissions criteria and its students' success in dental school.

Postural Assessment of Students Evaluating the Need of Ergonomic Seat and Magnification in Dentistry.

Dental students using conventional chairs need immediate change in their posture. Implementing an ergonomic posture is necessary as they are at high risk for developing musculoskeletal disorders. This study recommends the use of an ergonomic seat and magnification system to enhance the visibility and the posture of an operator. The aim of this study is to make a foray into the hazards caused by inappropriate posture of dental students while working. It also aims at creating a cognizance about the related health implications among the dental fraternity at large, and to understand the significance of adopting an ergonomic posture since the beginning of the professional course. In the present study, postures have been assessed by using rapid upper limb assessment (RULA). This method uses diagrams of body postures and three scoring tables to evaluate ones exposure to risk factors. Ninety students from II BDS (preclinical students in the second year of dental school) were assessed in three groups using three different seats with and without magnification system. The results recorded significantly higher RULA scores for the conventional seats without using the magnification system compared to the SSC (Salli Saddle Chair-an ergonomic seat) with the use of magnification system. A poor ergonomic posture can make the dental students get habituated to the wrong working style which might lead to MSDs (Musculoskeletal diseases). It is advisable to acclimatize to good habits at the inception of the course, to prevent MSDs later in life.

Early Performance in a Humanistic Medicine Course as a Predictor of Dental Students’ Later Clinical Performance

The purpose of this study was to test the hypothesis that dental students' early ability to demonstrate a humanistic approach with patients is associated with later clinical performance. A first-year humanistic medicine course, Patient Doctor I (PDI), at Harvard School of Dental Medicine combines training in conducting the medical interview with human values, placing a high value on strengthening relationships with patients and emphasizing empowerment, respect, and strong communication skills. Retrospective data were collected in the following domains: PDI course evaluations, admissions information, National Board Dental Examination Parts I and II scores, and Promotions Committee and faculty evaluation scores for hand skills and humanistic and interactive patient-student skills. Planned linear contrasts comparisons were performed for each clinical outcome variable. Tests to support the a priori hypothesis of linear relationships between PDI evaluation ratings and clinical performance, defined as hand skills and humanistic and interactive patient-student skills scores, were significant, both at p=0.03. This study demonstrated the feasibility of measuring dental students' humanistic qualities during the first year. Humanistic qualities (PDI performance) during the first year were found to be associated with clinical performance in the third year of dental school.

What are the Ethical Implications of Helping a Colleague Obtain Unearned Continuing Education Credit?

Q I have been a general dentist for 25 years and recently attended the local dental society’s meeting and continuing education seminars. On the second evening of the meeting, my dental school alma mater hosted its annual reception. I bumped into a dentist who had been one year behind me in dental school. During his first year of dental school, I had been assigned as his mentor. My efforts to help my colleague with his studies and behavior factored into his making it through dental school, but he had a tendency to cut corners.

Perception and attitude about systemic health and periodontal disease among dentistry undergraduates.

To evaluate the perceptions held by dentistry undergraduates about the relationship between general health and periodontal disease. In addition, student knowledge about treatment of patients with systemic disorders was also examined. Participants were all undergraduates in the last year of dental school from three different universities (N = 253). Inclusion criteria were students enrolled in their last year of the dental curriculum and who agreed to participate in the research. After the participants filled out a structured questionnaire, the results were analysed using Epi Info 3.5.1 software and the chi-square, Friedman and Wilcoxon tests. The majority of participants recognised the relationship between periodontal and cardiac disease and diabetes mellitus. However, only half of the participants were aware of the relationship between periodontal disease and stroke (50.5%). In relation to caring for patients with systemic diseases, 61.4% of students surveyed did not know the blood glucose level that characterises a hypoglycemic status. The majority of participants (61.8%) stated the importance of evaluating vital signs prior to dental treatment. However, only 13.3% of the participants included temperature and respiratory rate as vital signs. The perception and attitude of undergraduates about the items on the questionnaire were deficient. Thus, a more holistic view of the patient is warranted within dental education, promoting health and quality of life.

A Case‐Based and Team‐Based Learning Model in Oral and Maxillofacial Radiology

The purpose of this article is to describe the process of transitioning a traditional face-to-face oral and maxillofacial radiology (OMR) lecture course to a case-based, team-based learning model for students ready to enter their fourth and final year of dental school. Data were collected from 294 new fourth-year students (Classes of 2009, 2010, and 2011) who participated in the newly formatted OMR course. At the time the course was taken, students had completed one year of clinical experience in taking and evaluating radiographic images on patients with various clinical conditions. Each class of approximately 100 students was divided into ten teams of ten each, and a topic on oral and maxillofacial lesions was assigned to each team. The teams researched their assigned topics, created PowerPoint presentations, and posted them on the course management system Blackboard site. The instructor posted on Blackboard eight to ten cases representing various lesions on that topic. Minimal clinical history was released at that point. Students reviewed the teams' PowerPoint presentations and the cases, answered the questions for each case, and turned in written assignments to be graded. The diagnoses were discussed in class. An end-of-course survey found that 71 percent of the students felt the case-based instruction helped them learn the content in a more comprehensive manner and 77 percent felt the in-class discussion increased their knowledge of radiographic interpretation. Some students said they felt uncomfortable being called on randomly during the class discussion. National Board Dental Examination results for the classes of 2009 and 2010 showed slight improvement when compared to national scores. As a result of student feedback, the course continues to be offered in the case-based, team-based format.

Dental Students’ Attitudes Toward Underserved Populations Across Four Years of Dental School

The objective of this study was to assess dental students' attitudes toward underserved populations across their four years of dental school. Students at the Herman Ostrow School of Dentistry of the University of Southern California were invited to take part in the study. Participating students completed a questionnaire on their attitudes toward the underserved at three time points: 1) during orientation week; 2) at the end of their second year after taking part in some community dental programs; and 3) at the end of their fourth year after they had completed all their mandatory and volunteer rotations in community dental programs. Students' attitudes were measured in four categories: societal expectations, dentist/student responsibility, personal efficacy, and access to care. First-year students scored 85 out of a maximum of 115 on the questionnaire. Female students scored higher than male students (P=0.006). Age, debt, and past history of volunteer work were not related to first-year students' total attitude scores; however, students with a history of volunteer experience scored higher on the dentist/student responsibility category (P=0.04). Students' attitude scores declined across the four years of dental school (P=0.001). The same patterns were evident for all categories except societal expectations. The decline was not related to age, gender, debt, or volunteer work experience. Follow-up studies are needed to help explain the factors that may be related to this decline.

Oral Health Attitudes and Behavior among a Group of Dental Students in Bangalore, India

To evaluate self-reported oral health attitudes and behavior among a group of dental students in Bangalore, India and to compare the oral health attitudes of students of different years of dental school. A self-administered questionnaire based on a modified version of the Hiroshima University Dental Behavior Inventory (HU-DBI) was administered to 250 dental students. Significant differences (P<.05) were observed among students of different years in the degree of worrying about the color of the teeth, not having been to the dentist before and brushing each tooth carefully. Strongly significant differences (P<.001) were observed among students of different years in brushing the teeth twice daily, being satisfied with the appearance of the teeth, cleaning the teeth well without toothpaste, visiting dentist only when having a toothache, taking too much time to brush their teeth, worrying about having bad breath and using mouth rinse on a regular basis. Among dental students, the overall knowledge of oral health was good, even though there were deficits in knowledge in a few areas. The oral health attitudes and behavior of dental students improved with increasing levels of education.

Impact of a Novel Dental School Admission Test on Student Performance at Innsbruck Medical University, Austria

Since the year 2000, prospective dental students at Innsbruck Medical University, Innsbruck, Austria, have undergone both theoretical and practical preadmission exams, called the Dental Admission Test (DAT). The aim of this investigation was to assess the suitability and outcome of this selection practice. Five classes from 2001 to 2005 (N=97; forty-three female, fifty-four male) were retrospectively reviewed. DAT results were compared with student performance, gender, ability to graduate on time, and dropout rates. Furthermore, the influence of a previous medical degree was evaluated. The t-test was used to analyze correlations between the results of the DAT and the following: gender, students who graduated on time, and students who had previously completed a medical degree. Pearson's correlation coefficient (r) was applied to analyze correlations among test scores, age, and students' performance during the first clinical year. Students graduating on time were noted to have significantly better DAT results; students with a previous medical degree showed significantly better grades during their first clinical year. The difference between the performance of male and female applicants on the DAT was not significant. Correlation was found between DAT results and dental school performance (r=-0.462). We conclude that the DAT may reduce dropout rates by excluding applicants unlikely to be successful in practical courses and that DAT scores are a reliable tool to predict student performance during the first clinical year of dental school in Innsbruck.

Correlation of Quantity of Dental Students’ Clinical Experiences with Faculty Evaluation of Overall Clinical Competence: A Twenty‐Two‐Year Retrospective Investigation

The purpose of this study was to investigate the correlation between the quantity of a student's clinical experiences in the final year of dental school and the student's overall clinical competence at graduation, as evaluated by faculty at the University of Iowa College of Dentistry. Further, the authors sought to determine whether this correlation changed over time, as new generations of students come to dental school. Information including year of graduation, age at graduation, final grade in the course Clinical Competencies in Comprehensive Care, and final total Clinical Experience Units (CEUs) earned by each student in the D4 Family Dentistry Clinic was collected for 1987-2008 graduates of the University of Iowa College of Dentistry. Spearman's rank correlation coefficient (r(s)) was computed for the association of final clinical course grade and final CEU total for each graduation year. The correlation between final course grade and final CEU total was variable, ranging from moderately strong (r(s)=0.614, Class of 1991) to negligible (r(s)=-0.013, Class of 2008). This correlation generally tended to become weaker over time. The results of this study suggest that the terminal quality of a dental student's work is not solely a function of repetitions of prescribed procedures and that repetition of procedures may have even less influence on the quality of clinical performance for the new generation of dental students.

Communication Skills Instruction Utilizing Interdisciplinary Peer Teachers: Program Development and Student Perceptions

Lack of curricular time, faculty time, and funding are potential limitations for communication skills training in dentistry. Interdisciplinary collaboration amongst health care faculties could address these limitations. This article describes the development, implementation, and student perceptions of a communication skills program in dentistry. The program has four components: Knowledge, Observation, Simulation, and Experience (KOSE) and spans over the second and third years of dental school. KOSE allows students to obtain knowledge of and observe effective communication skills and practice these skills in the simulated and nonsimulated environment. A key feature of KOSE is the utilization of fourth-year medical and dental students as peer teachers. Evaluation of KOSE was geared toward student perceptions. Cross-sectional data were gathered via written surveys from 143 learners (second- and third-year dental students) in 2006-07. Students perceived the ability to recognize effective communication, demonstrated awareness of their communication strengths and weaknesses, and reported that skills gained were transferable to actual patient care. Interdisciplinary collaboration was a feasible way to address the lack of resources in the development of a communications skills program, which was perceived to be worthwhile by learners.

Correlation of Admissions Criteria with Academic Performance in Dental Students

Our purpose was to compare admissions criteria as predictors of dental school performance in underachieving and normally tracking dental students. Underachieving dental students were identified by selecting ten students with the lowest class grade point average following the first year of dental school from five classes, resulting in a pool of fifty students. Normally tracking students served as a control and were randomly selected from students who had completed their first year of dental school not in the underachieving group. Admission measures of college grade point average (GPA), science grade point average (SGPA), academic average (AA), Perceptual Ability Test (PAT), college rigor, and academic load in college were evaluated with descriptive statistics, correlation, and regression analysis with first-year and graduating GPA as the dependent variables. Admissions criteria were generally weak predictors of first-year and graduating GPA. However, first-year dental school GPA was a strong predictor (R(2)=0.77) of graduating GPA for normally tracking students and a moderate predictor (R(2)=0.58) for underachieving students. Students who completed the first year of dental school having a low GPA tended to graduate with a low GPA. Therefore, remediation and monitoring would be important during the dental school experience for these students.

What Enhances Underrepresented Minority Recruitment to Dental Schools?

This study examined the factors influencing the proportion of underrepresented minority students (URM) in dental schools. Using a comprehensive recruitment model, it considered the relative importance of community characteristics (population demographics, oral health policies, dental care system, and university environment), dental school characteristics (Pipeline-supported, mission, and financing), and community-based dental education (CBDE) characteristics of the dental school on recruitment of URM students. Data come from a national survey of dental school seniors and a variety of publicly available sources. Three outcome variables measure URM recruitment: percent URM, percent Hispanic, and percent African American in the first year of dental school. Multivariable results revealed that the most important factors predicting a higher percent URM in first-year classes were a higher proportion of URM clinical faculty and graduating students' perceptions that their clinical rotation experience improved their ability to care for diverse groups. For percent Hispanic in the first year, a higher proportion of URM clinical faculty and students spending more time in clinical rotations predicted greater Hispanic recruitment. Graduating students' perceptions that they were less prepared to treat diverse groups were directly associated with the proportion of Hispanic students in the class. For a higher percent of African Americans in the first-year class, the most important factors were a higher proportion of blacks in the county, support from the national Pipeline program, and graduating students' perceptions of better preparedness to integrate cultural differences into treatment planning. Higher total financial aid awarded by the school was negatively associated with recruitment of African Americans. Results suggest some improved URM recruitment strategies for dental schools.

The Relationship Between Gender and Postgraduate Aspirations Among First‐ and Fourth‐Year Students at Public Dental Schools: A Longitudinal Analysis

The purpose of this study was to examine gender differences and other predictors of postgraduate plans among U.S. dental students. A national sample of dental students was surveyed in their first and fourth years of dental school. Female first-year students were less likely than male students to express interest in specialization in endodontics and oral surgery. Fourth-year students who had a dental school mentor, a high GPA, and encouragement from significant others were more likely to apply for postgraduate training. Gender and first-year interest in dental specialization did not affect the likelihood of applying for postgraduate training in the fourth year. Female fourth-year students were more likely to predict that they would be an associate in a practice five years following graduation. The results suggest that mentoring and faculty encouragement are important influences on dental students' plans for postgraduate education.

Predicting Performance in Canadian Dental Schools: The New CDA Structured Interview, a New Personality Assessment, and the DAT

Using a sample of dental students (N=373) from four Canadian dental schools, this longitudinal study determined whether the new Canadian Dental Association (CDA) structured interview was a predictor of clinical and academic performance. The new interview predicted clinical performance in the third and fourth years of dental school, but not academic performance. The Canadian Dental Aptitude Test (DAT) continued to predict first- and second-year academic performance, but not clinical performance in the senior years. A personality factor, "Conscientiousness," predicted clinical and academic performance to various degrees across the four years of dental school. A second personality factor, "Openness to Experience," predicted third-year academic performance. The results suggest that a combination of scores from the DAT, a valid measure of personality, and a well-designed structured interview will provide the best prediction of those applicants who will do well in both the academic and clinical aspects of dental school.

Problem analysis as a model for higher education: a pilot experience with students of the 3rd and 4th years of dental school

No presente trabalho os autores investigam resumidamente o desenvolvimento da odontologia e de seu ensino. Discorrem sobre o perfil do cirurgião-dentista atual e a ineficácia de sua atuação frente às demandas populacionais. Como experiência pedagógica, promoveu-se, em 5 dias e utilizando três períodos em cada, um curso intensivo de capacitação em Saúde da Família a alunos do terceiro e quarto anos de uma Faculdade de Odontologia particular do interior do Estado de São Paulo. Ao final do curso, os alunos responderam a um questionário semi-estruturado e avaliaram as diferenças, vantagens e desvantagens do uso no ensino de Odontologia do modelo tradicional e do modelo da problematização preconizado por Freire6 (1996).

Use and Perceived Effectiveness of Student Support Services in a First‐Year Dental Student Population

The purpose of this study was to determine the severity of problems common to the first year of dental school and to assess the use and perceived effectiveness of formal and informal peer and professional support programs in addressing those problems. First-year students at one California dental school were surveyed on the severity of problems encountered, support services used, and perceived effectiveness of services. Results indicated that the problems perceived as most serious by students in this sample were of an emotional nature relating to academic performance. Findings showed that students relied heavily on themselves and on informal advice from peers to handle problems and that they perceived these resources to be very effective. Findings also showed that low-ranking students used both formal and informal resources to resolve problems and that females used resources outside of the school more than males did. Results of the study offer some evidence to support providing both formal and informal peer and faculty support programs for first-year dental students. Results also provide insight into the use of peers and "self" to resolve problems common to the first year of dental education.

Strategies for Making Research More Accessible to Dental Students

Increasing student involvement in research has potential rewards for both faculty and students. Both groups have demands on their time, interest, and commitment that frequently result in low student research activity. Dental schools can make research more accessible to students by increasing student understanding of the importance of research, establishing rotating research positions, providing compensation, pursuing projects that interest students, and providing time in the curriculum for research by restructuring the basic sciences curriculum during the first two years of dental school. No attempt to make the research process easier or more accessible should compromise the integrity of the scientific process, but increasing students' research involvement will pay long-term dividends for dental schools and the profession.
