Early practice makes histology masters: The use of a formative assessment quiz to prepare histology learners for a high-stakes final examination.

Assessment of learners in the anatomical sciences is a complex task as it not only tests students' fact knowledge, but also the analysis of visual information. Sometimes, novice histology learners must acquire image recognition skills of microscopic structures in a short time frame. This paper describes a strategy of offering first year dental students at the University of Michigan a short, non-grade contributing, formative assessment quiz in order to better prepare them for a high-stakes, final summative histology examination. Data collected over 7 years indicate that students, who made use of this formative assessment opportunity, performed significantly better in their summative examination than students, who did not. Especially early practice quiz users profited most. Students, who used the practice quiz until they achieved a perfect score, also had statistically higher final examination scores. Students, who did not use the practice quiz, had a significantly lower cumulative D1-year Grade Point Average (D1-GPA) than students, who did, indicating that academically weaker students often underuse supporting learning resources. In general, scores from the Dental Admission Test (DAT) were weak predictors of learning success in the DENT 510 histology course. In contrast, the D1-GPA values had a medium strength positive correlation with final histology examination scores. The major problem that was encountered with this practice quiz strategy was that many students waited until close to the day of the final examination before taking advantage of this feedback opportunity, thereby reducing its potential benefit for improving their overall learning strategy for histology.

A Comparison of Admissions Data Between Virtual and In-person Dental School Interviews

Objectives: The COVID-19 pandemic forced many dental schools to conduct some or all of their interviews virtually. The purpose of the study was to evaluate whether an association existed between interview setting and applicant characteristics, specifically focusing on the difference in the interview score between applicants who chose virtual interviews and those who chose in-person interviews.Methods: Demographic and admission data were obtained from the 101 interviewed candidates from the XXXX 2021-2022 application cycle. Distribution of demographics and interview preference were assessed. Simple and multiple generalized linear models (GLM) were run to examine the difference in the applicants’ interview score between in-person and virtual interviews.Results: Of the 29 in-person interviews, 16 (55.17%) were offered acceptances, while 31 (43.06%) of the 72 virtual interviews were accepted, a difference that was not statistically significant (p-value = 0.380). Preference for the interview format was not associated with any of the applicants’ factors including gender, current residence (the four bureau-designated regions), overall grade point average (GPA), science GPA, Dental Admissions Test (DAT) Academic Average score, and perceptual ability test (PAT) score. In addition, there was no statistical difference in the interview score between the two interview formats.Conclusions: The effect of virtual interviewing on interview scores and applicants’ admission rate was found to be statistically insignificant. If further study with larger sample sizes confirms this finding, virtual interviewing could be considered as a viable alternative to in-person interviewing in the dental school admissions process.

Evaluating the use of HEIghten critical thinking assessment to monitor critical thinking in dental students.

Critical thinking and evidence-based dentistry are skills that dental students are required to demonstrate, but monitoring and quantifying progress can be challenging. This study is investigating whether the HEIghten critical thinking assessment (HCTA) could be used as a potential tool, both for use prior to admitting students, and to monitor whether the students' skills improve over their time at dental school. Freshman dental students (n=92) were given the HCTA during their first semester of dental school. Statistical analyses were then performed to examine the association of Dental Admission Test (DAT) scores (overall, perceptual ability, and total science) and Grade Point Average (GPA) (overall and science) on critical thinking scores (total, analytic, and synthetic). There was a significant positive association between GPA, DAT scores and critical thinking scores. Our results indicate that the HCTA may be a useful tool to enable monitoring of students analytical and synthetic skills throughout their time at dental school.

Performance of ChatGPT 3.5 and 4 on U.S. dental examinations: the INBDE, ADAT, and DAT.

Recent advancements in artificial intelligence (AI), particularly tools such as ChatGPT developed by OpenAI, a U.S.-based AI research organization, have transformed the healthcare and education sectors. This study investigated the effectiveness of ChatGPT in answering dentistry exam questions, demonstrating its potential to enhance professional practice and patient care. This study assessed the performance of ChatGPT 3.5 and 4 on U.S. dental exams - specifically, the Integrated National Board Dental Examination (INBDE), Dental Admission Test (DAT), and Advanced Dental Admission Test (ADAT) - excluding image-based questions. Using customized prompts, ChatGPT's answers were evaluated against official answer sheets. ChatGPT 3.5 and 4 were tested with 253 questions from the INBDE, ADAT, and DAT exams. For the INBDE, both versions achieved 80% accuracy in knowledge-based questions and 66-69% in case history questions. In ADAT, they scored 66-83% in knowledge-based and 76% in case history questions. ChatGPT 4 excelled on the DAT, with 94% accuracy in knowledge-based questions, 57% in mathematical analysis items, and 100% in comprehension questions, surpassing ChatGPT 3.5's rates of 83%, 31%, and 82%, respectively. The difference was significant for knowledge-based questions (P=0.009). Both versions showed similar patterns in incorrect responses. Both ChatGPT 3.5 and 4 effectively handled knowledge-based, case history, and comprehension questions, with ChatGPT 4 being more reliable and surpassing the performance of 3.5. ChatGPT 4's perfect score in comprehension questions underscores its trainability in specific subjects. However, both versions exhibited weaker performance in mathematical analysis, suggesting this as an area for improvement.

Lessons learned from a non-traditional application process: Integrating user experiences to inform admission application design.

The research aim was to gather applicant expectations and perspectives with a user-centered approach during a pilot application process for a new dental school. The goal was to inform future admissions practices at our institution and for programs broadly. The High Point University admission team developed an electronic application external to current centralized services that was launched from May to August 2022. Participants who completed the application were requested to complete an electronic survey of closed- and open-ended questions about the factors influencing their application decisions, feedback about how to optimize the experience, and their overall satisfaction using a Net Promoter Score. A total of 303 applicants (79% response rate) completed the survey about their application experience. The most influential reason for applying to the program was the optional Dental Admissions Test requirement (43%). Participants frequently referenced a need for a more human-centered process focused on the candidate rather than their numerical values and that the process should be smooth, straight-forward, short, easy, and simple. Participants requested that experiences should be weighed the most in the application process followed by letters of recommendation. Most applicants were "promoters" (68%) for the program with a Net Promoter Score of 62. Moreover, 32% and 45% rated the application process as the best or better application experience compared to other programs. Programs can benefit from collecting applicant's (i.e., users) opinions and feedback about their expectations and experiences to inform more user-centered application processes.

Association of admissions factors with student performance in preclinical operative dentistry.

Admission to dental school is based on various factors including academic achievements in undergraduate coursework and the Dental Admission Test (DAT) scores. Students' success in an operative course requires fundamental knowledge, hand skills, spatial awareness, and self-assessment ability. The goal of this study is to evaluate how admissions factors, such as Grade Point Average (GPA) and DAT, including the Perceptual Ability Test (PAT), relate to students' academic and preclinical performance and self-assessment skills in preclinical operative dentistry. A total of 239 students were included from seven class years (2016-2022). Third-year dental students participated in a preclinical operative dentistry course. At the end of the course, they took the final multiple-choice exam and performed four competency examination procedures: Class II amalgam preparation and restoration and Class III resin-composite preparation and restoration. Calibrated faculty graded students' work independently and students also self-assessed their performance using the same rubrics as faculty. Linear regressions were performed to estimate the association between the admission factors with the mean faculty scores (measuring preclinical performance), student-faculty (S-F) gap scores (evaluating self-assessment skills), and their final didactic exam scores. Overall, students' self-assessment was higher compared to faculty score. Linear regression analysis demonstrated positive correlations between the PAT and students' preclinical performance as well as between the DAT and their didactic exam scores. In general, S-F gap score decreased as PAT score increased, and it was statistically significant lower for the Class III preparation, indicating a better self-assessment skill. No correlations were observed between student performance and GPA scores. The findings from the association between student performance and admission factors may play an important role in the dental school admissions process and assist students who may benefit from early faculty intervention and support.

Admissions data as predictors for student performance in restorative dentistry.

The purpose of the study was to determine the relative predictive power of admissions criteria and predoctoral academic performance in the area of restorative dentistry in order to better understand and guide the dental school admissions process. In addition to admissions criteria, student performance in restorative dentistry, such as the Final Restorative Treatment course, the didactic and preclinical examinations, and the objective structured clinical examinations (OSCE), was measured for the 172 predoctoral students representing the graduating classes of 2017-2021. The association between the didactic score in restorative dentistry and grade point average (GPA, p=0.009) and Dental Admission Test (DAT, p=0.002) score was statistically significant. Although no statistically significant association was found between preclinical scores and gender, GPA, or DAT, there was a statistically significant association between preclinical scores and the Perceptual Ability Test (PAT) score (p=0.012). Preclinical scores included laboratory examinations for fixed prosthodontics, such as crown preparation and temporization, representing hand skills assessment. Finally, there was no statistically significant association found between the OSCE score and any of the admissions criteria. The dental admissions criteria could play a role in predicting academic performance in the didactic portion and preclinical component of restorative dentistry.

Evaluation of a pipeline program at strengthening applications, increasing diversity, and increasing access to care.

To evaluate the outcomes of a dental pipeline program at strengthening dental school applications, growing the diversity of dental students, and increasing access to care METHODS: This program evaluation used a descriptive and quasi-experimental retrospective study design. Researchers analyzed secondary data, from a dental pipeline program, for the years 2011-2018. Descriptive statistics were used to describe short-term and intermediate outcomes and impact. Associations were tested using paired t-test, 2-sample t-test, analysis of variance, and chi-squared test RESULTS: Ninety-eight scholars completed the 10-week program. The majority of scholars were female (70%), non-Hispanic or Latino (76%), non-White (72%), and pursuing baccalaureate degrees (94%). After completing the program, the mean Dental Admission Test (DAT) Academic Average Score (AAS) increased (16.0vs. 17.5, P<0.01). Significant associations were revealed between post-program DAT AAS and being accepted into dental school (P=0.02). Associations remained when stratified by gender (male P=0.01) and ethnicity (P=0.03). The majority of scholars (71%) applied to the host school. Over half of the scholars matriculated to dental school (55%). Twenty-nine scholars (30%) graduated from the host school. Graduates report choosing careers in private practice (38%), public health (24%), corporate dentistry (17%), and the military (3%) CONCLUSION: Dental pipeline programs are effective at strengthening dental school applications, increasing DAT AAS, growing the diversity of dental students, and increasing access to care. Dental education needs to examine barriers dental pipeline programs do not typically address, such as the high cost of applying to dental school, and identify additional ways to support underrepresented minority students entering into dentistry.

Correlation between Advanced Dental Admission Test performance and dental MATCH success

The Advanced Dental Admissions Test was developed in 2016 to aid residency programs evaluate qualified applicants. Since its conception, however, there have been no studies seeking to evaluate the usefulness of the exam regarding an applicants' ability to match with a residency program through the Postdoctoral Dental Matching Program (MATCH). The aim of this study was to evaluate the impact of the Advanced Dental Admission Test performance on student MATCH success into a post-doctoral pediatric residency program. This retrospective study evaluated the academic records of pediatric residency applicants using the ADEA PASS and MATCH program between 2017 and 2019. Five scholastic and 7 demographic variables were extracted from student ADEA PASS applications. Applicant MATCH status and preference was obtained from the Postdoctoral Dental Matching Program. Descriptive statistics for each application cycle was calculated and used to evaluate applicant demographic and scholastic data. Correlation coefficients assessed for associations between scholastic/demographic factors and MATCH status/preference. Logistic regression models estimated the probability of MATCH status/preference. Significance was set at 5%. An association was found between ADAT scores and MATCH status, but the influence was minimal (odds ratio: 1.004, 95% confidence interval: 1.001-1.008). Applicant age (P < 0.0216) and dental schools that ranked students (P < 0.0002) were the most significant factors for MATCH status and preference, respectively. ADAT scores played a minimal role in applicants matching to pediatric residency programs. Applicant age and schools that provide class ranks were found to be significant predictors when considering MATCH status and preference to pediatric residency programs.

Is it time to incorporate physics into the Dental Admissions Test?

Although physics is a pre-requisite for dental students prior to matriculation it is not tested on the Dental Admissions Test (DAT). The concepts of physics are found throughout the dental profession, and by testing it on the DAT dental students will be better equipped to relate physics to their field and help advance it. The purpose of this paper is to make the argument for why it should be tested, as well as eliminating some of the superfluous topics on the DAT (ecology, environmental sciences, and plant physiology). This paper will focus on a few of concepts already taught in dentistry, and explore how physics principles apply to several of them. We want to emphasize the importance of physics and how testing even the most basic concepts will help prepare students to "think outside the box". Classical physics, specifically Newtonian Mechanics, has several applications in nearly all areas of dentistry: restorative, orthodontics, prosthodontics, and surgery. The testing of basic formulas studied in the pre-requisite physics classes will help ease the transition from college to dental school. Modern physics, namely Quantum Mechanics, also plays a significant role in current dental diagnostics and therapeutics. Additionally, with the development of the Integrated National Board Dental Examination (INBDE) as a replacement for the old NBDE part 1 and 2, there are topics tested that specifically focus on physics: Foundational Knowledge Areas 2 and 3. Thus, it is critical that the student dentist be familiar with these concepts. It is important to note that scientific changes occurring in the health sciences almost mandates students be familiar with concepts rooted in physics. It is then proposed that physics be incorporated into the exam, either with the natural sciences or within the quantitative reasoning section, in addition to eliminating topics not relevant to the dental field.

Contemporary appraisal of factors influencing pediatric dental program directors' selection of residents.

With the increasing number of applicants and changes to information available in applications, pediatric dentistry program directors must adapt the resident selection process. The evaluation approach was significantly impacted when the National Board Dental Examination (NBDE) changed to a pass/fail grading system. The purposes of this are study to examine what criteria pediatric dentistry program directors now use to select residents, and to evaluate current criteria against those used in the past. A 30-item survey was structured similar to a previous questionnaire used in 2005. An invitation to participate was sent via email to all pediatric dentistry program directors for the 82 Commission on Dental Accreditation (CODA)-accredited programs located in the United States and Canada. Anonymous responses were analyzed. There were 58 responses (70.7% response rate). The overall most important factors were clinical grades, dental school class rank, dental school grade point average (GPA), and applicant's essay. The least important factors were the applicant being a graduate of the program's dental school, Advanced Dental Admission Test (ADAT) score, and applicant's fluency in a second language. The factor that had the most significant increase in importance from 2005 is the applicant's essay, followed by dental school reputation and the dental school's pediatric program reputation. The most important factors to program directors are clinical grades, dental school class rank, dental school GPA, and applicant's essay. The applicant's essay has increased in importance since 2005.

The Multiple Mini Interview as a Dental School Admission Tool: Can It Predict Noncognitive Traits Associated with Professional Behaviors?

The aim of this study was to investigate the reliability and validity of the Multiple Mini Interview (MMI) process and to assess its use as an admission tool to predict noncognitive traits associated with professional behavior during patient care in one cohort of dental students at a single U.S. dental school. Data were analyzed for the 95 candidates who matriculated and graduated as part of the 2017 graduating cohort at the University of Michigan School of Dentistry. All MMI interviewees for one cycle of admissions rotated through ten stations: two traditional interview question stations and eight scenario stations measuring domains that included four questions scored on a five-point Likert scale. Generalizability theory analysis showed the MMI to have good reliability (G Coefficient of 0.74). Station reliabilities (Cronbach's alpha) ranged from 0.88 to 0.92. MMI scores showed a positive significant correlation with students' scores on the Dental Admission Test and Perceptual Ability Test, D1 cumulative GPA, and D4 Patient Management grade. MMI scores positively correlated with professional behaviors relating to three domains-openness, conscientiousness, and emotional stability-thus demonstrating good predictive validity for measuring noncognitive traits associated with professionalism. This study found that the MMI was a reliable and valid tool that predicted key behavioral traits associated with professionalism in dental students.

Predicting professional school performance with a unique lens: are there other cognitive predictors?

BackgroundWe investigated the associations between admissions criteria and performance in four cohorts of pre-dental MS in Oral Health Sciences (OHS) program at Boston University Schools of Medicine and Dental Medicine. Previously we have reported that OHS serves as a successful pre-dental pipeline program for students from underrepresented groups.MethodsWe evaluated academic variables that further affect overall graduate GPA and grades in the first year dental school courses taken by OHS students at Boston University between 2012 and 2016 as part of the MS curriculum. Demographic data, region of residency, undergraduate grade point average, number of science and math credits, major of study, dental admissions test scores and undergraduate institution were collected. The competitiveness of the undergraduate institution was scored based on Barron’s Profiles of American Colleges. OHS-GPA was assessed and individual grades in two first year dental school courses taken as part of the OHS curriculum were collected. Analysis of variance, the Chi-square test and Fisher’s Exact test were utilized to assess associations between academic performance parameters, successful program completion and matriculation to dental school.ResultsResults indicate that undergraduate major, age and number of science course credits taken had no impact on MS performance in the Boston University MS in Oral Health Sciences program; however, students who took an undergraduate course in Physiology performed better than those who did not (p = 0.034). This was not the case with courses in Cell Biology and Biochemistry. Students with DAT scores over 20 academic average (p = 0.001), 18 total science average (p = 0.001) and 22 reading comprehension (p = 0.004) performed better in dental school courses taken in OHS.ConclusionWe report that strong test scores, attending a mid or highly rigorous undergraduate institution and completion of an undergraduate Physiology course are positive predictors. We hope these findings will guide admission’s decisions and improve recruitment to, and future success of, graduate student’s pursuit of professional school. Understanding alternative predictors of success may help to reduce the intrinsic bias among applicants from underrepresented groups and continue to look beyond the DATs (or MCATs) to decrease the gap between professionals from underrepresented groups and those they serve.

Unintended Demographic Bias in GPA/DAT-Based Pre-Admission Screening: An Argument for Holistic Admissions in Dental Schools.

Screening of applicants for admission to dental school often relies on metrics such as overall undergraduate grade point average (oGPA) and Dental Admission Test (DAT) scores to identify desirable prospective students. The aim of this study was to assess unintended selection bias that may be overlooked or mitigated with holistic review and the influence of metrics at one U.S. dental school. Descriptive range analysis of oGPA and science GPA (sGPA), DAT scores, and total experience hours was performed for the 2017-18 application cycle for all applicants, those who self-identified as underrepresented minorities (URM), non-traditional applicants (with postbaccalaureate or master's coursework), and socioeconomically disadvantaged (SED) applicants reporting low parental employment-occupation scores. The results showed that, in screening this school's applicant pool, metrics-based candidate selection would favor those candidates in the 80th percentile of GPA and DAT Academic Average (AA) scores. Unless mitigated by other screening factors, reliance on these metrics tended to favor majority, traditional, and non-URM SED applicants. These findings suggested that the new admitted class would likely have fewer dental experience and employment hours than in the overall applicant pool. Interestingly, more non-traditional, SED, and URM applicants could be considered if higher general employment and dental experience hours had more impact in the screening process. These results illustrate the importance of deliberately considering non-cognitive metrics and characteristics to admit a more diverse student body.

Elements of Undergraduate Education Related to Students' Academic Performance in the First Year of Dental School.

The aim of this study was to improve understanding of predictors of student success in dental school. A total of 178 student records from the Classes of 2015 and 2016 at a U.S. dental school were reviewed for this retrospective study. The records assessed included admissions files with such elements as scores on the Dental Admission Test (DAT), participation in a pipeline program, and undergraduate transcripts; academic records from the first term of dental school (class rank, course remediation, and withdrawal/dismissal from dental school); and National Board Dental Examination (NBDE) Part I results. The results showed that the DAT Perceptual Ability Test was positively related to performance in the first term of dental school (p=0.030). The DAT Academic Average (p<0.0001) and participation in a pipeline program (p=0.006) were found to be predictors of performance in the lower 25% of the class by end of first term rank. Taking organic chemistry in a summer term during undergraduate study was identified as a predictor variable for dismissal, withdrawal, or entry into a decompressed curriculum (p=0.025). Although this analysis found that traditional predictors of academic success in dental school were associated with strong academic performance in the study sample, it also provided a more complex assessment of factors that may be associated with students who struggle in the first year. As the vast majority of students in this sample successfully completed dental school, the results were not sought to inform admissions criteria, but rather to help academic and student affairs officers identify at-risk students in order to offer timely intervention.

Improving Diversity of Dental Students Through the Boston University Master's of Oral Health Sciences Postbaccalaureate Program.

Boston University Goldman School of Dental Medicine (GSDM), in collaboration with Boston University School of Medicine, introduced the Oral Health Sciences (OHS) pipeline program in 2005 to enhance the academic preparedness of students from underrepresented minority (URM) groups for dental school admission. The aim of this study was to evaluate the OHS program's success in preparing URM students for dental school, as measured by acceptance to dental school and performance in the first and second years. Data on 2005-15 program enrollees were collected from admissions records, the registrar, and the Office of Institutional Research on students' race/ethnicity, undergraduate and OHS grade point average (GPA), and Dental Admission Test (DAT) scores. Acceptance to dental school and performance at GSDM for non-URM OHS graduates, URM OHS graduates, and non-OHS dental students were compared. A total of 55 URM students completed the OHS program during this period, with 49 successfully matriculating to a dental school in the U.S. and 33 attending GSDM. Average OHS GPA was higher for those URM students accepted to dental school than for those who did not gain admission (3.36±0.30 vs. 2.94±0.19). Evaluation of the academic performance of URM OHS students in the first year (p=0.13) and second year (p=0.88) at GSDM showed that these students performed as well as the non-OHS and non-URM OHS students. These results demonstrate that the OHS master's program serves as a successful credential-enhancing program for dental school applicants, while also serving as a pipeline to increase the number of qualified applicants from URM groups.

Preliminary Performance of the Advanced Dental Admission Test (ADAT): Association Between ADAT Scores and Other Variables for Applicants to Residency Programs at a U.S. Dental School

Historically, dental residency programs have used numerical assessment criteria to evaluate and identify qualified candidates for admission. Recent elimination of such assessment tools has undermined many programs' holistic evaluation process. The Advanced Dental Admission Test (ADAT) was developed and recently piloted in hopes of addressing this issue. The aim of this study was to evaluate the preliminary performance and validity of the ADAT by exploring the association between ADAT scores and other variables for a sample of applicants to residency programs. The WebAdMIT admissions database was used to identify the test scores and educational and demographic information of 92 individuals who completed the pilot ADAT and were seeking a 2017 postgraduate specialty position at Indiana University School of Dentistry. The results showed that the ADAT had strong to weak correlations with certain applicant variables (p<0.05). No significant differences were found for age, race, school location, or country of origin. However, males performed better than females (p<0.05), and non-Hispanics performed better than Hispanics (p<0.01). ADAT component scores were also higher for individuals with a history of research activity (p<0.05). This study found that significant associations existed between the ADAT and indices typically associated with competitive applicants. These findings suggest that the ADAT may serve as a useful numerical assessment instrument, with the potential to identify high-performing candidates. Furthermore, the ADAT seemed to be a plausible option for programs seeking to incorporate a quantitative assessment instrument as part of a holistic candidate selection process.

Rethinking Dental School Admission Criteria: Correlation Between Pre-Admission Variables and First-Year Performance for Six Classes at One Dental School.

Admissions committees in dental schools are charged with the responsibility of selecting candidates who will succeed in school and become successful members of the profession. Identifying students who will have academic difficulty is challenging. The aim of this study was to determine the predictive value of pre-admission variables for the first-year performance of six classes at one U.S. dental school. The authors hypothesized that the variables undergraduate grade point average (GPA), undergraduate science GPA (biology, chemistry, and physics), and Dental Admission Test (DAT) scores would predict the level of performance achieved in the first year of dental school, measured by year-end GPA. Data were collected in 2015 from school records for all 297 students in the six cohorts who completed the first year (Classes of 2007 through 2013). In the results, statistically significant correlations existed between all pre-admission variables and first-year GPA, but the associations were only weak to moderate. Lower performing students at the end of the first year (lowest 10% of GPA) had, on average, lower pre-admission variables than the other students, but the differences were small (≤10.8% in all categories). When all the pre-admission variables were considered together in a multiple regression analysis, a significant association was found between pre-admission variables and first-year GPA, but the association was weak (adjusted R2=0.238). This weak association suggests that these students' first-year dental school GPAs were mostly determined by factors other than the pre-admission variables studied and has resulted in the school's placing greater emphasis on other factors for admission decisions.

Relationship Between Dental Students' Pre-Admission Record and Performance on the Comprehensive Basic Science Examination.

The Comprehensive Basic Science Examination (CBSE) is the entrance examination for oral and maxillofacial surgery, but its implementation among dental students is a relatively recent and unintended use. The aim of this study was to examine the relationship between pre-admission data and performance on the CBSE for dental students at the Columbia University College of Dental Medicine (CDM). This study followed a retrospective cohort, examining data for the CDM Classes of 2014-19. Data collected were Dental Admission Test (DAT) and CBSE scores and undergraduate GPAs for 49 CDM students who took the CBSE from September 2013 to July 2016. The results showed that the full regression model did not demonstrate significant predictive capability (F[8,40]=1.70, p=0.13). Following stepwise regression, only the DAT Perceptual Ability score remained in the final model (F[1,47]=7.97, p<0.01). Variations in DAT Perceptual Ability scores explained 15% of the variability in CBSE scores (R2=0.15). This study found that, among these students, pre-admission data were poor predictors of CBSE performance.

Comparison of Dental Students' PAT Scores with Their Performance in Preclinical Technique Courses: Identifying the Need for Early Interventions.

The aim of this study was to determine if lower scores on the Perceptual Ability Test (PAT) of the Dental Admission Test (DAT) predicted which dental students required remediation in three preclinical restorative dentistry courses at Rutgers School of Dental Medicine. The academic records of 489 dental students from the graduating Classes of 2010 through 2015 were evaluated. The results showed that, for all three courses (Preclinical General Dentistry I, Preclinical General Dentistry II, and Preclinical Fixed Prosthodontics), the remediating students had significantly lower mean PAT scores than did the passing students. A one-unit decrease in a student's PAT score was associated with a 43% increase in the odds of remediating the Preclinical General Dentistry I lab, a 29% increase in the odds of remediating the Preclinical Fixed Prosthodontics lab, and a 47% increase in the odds of remediating the Preclinical General Dentistry II lab. The mean PAT score for passing students was 18.84 (standard deviation 2.35), and the mean PAT score for students requiring remediation was 17.03 (standard deviation 2.18). Studies like this can be useful because if students at risk of failing these courses are identified early and appropriate supports are provided, the need for remediation may be reduced if not eliminated.
