This study attempted to determine if students with certain personality preferences outperform others over the course of the initial dental school year. The Myers-Briggs Type Indicator (MBTI) was used to assess the relationship between personality preferences and academic performance. One hundred and ninety-nine dental students in four successive first-year classes, 1983-86, participated. Pearson correlation coefficients were used to relate academic performance (first-semester, second-semester, and first-year GPAs) to personality preferences (EI, SN, TF, JP) and academic predictors (entering GPA and DAT scores). For personality preferences, all correlation coefficients were low and nonsignificant. In comparison, entering GPA and DAT (academic) scores were significantly correlated with first-semester, second-semester, and first-year GPAs. DAT (perceptual ability) scores showed a significant correlation with first-semester GPAs only.

In view of national concerns about student aptitude and overcrowded curricula, the effectiveness of review courses must be evaluated objectively. The present study is a statistical analysis of the impact of a review course on National Board Examination (NBE) Part I performance at the University of Detroit. The performance of dental students who had taken the course between 1985 and 1987 (N = 175) was compared to that of the prior three classes (N = 212). Analysis of covariance (ANCOVA) was used to adjust and compare mean scores on the NBE, using entering GPA and DAT scores, both measures of aptitude, as covariates. Only two of the five NBE scores demonstrated significant improvement. While aptitude contributed as much as 23 percent to NBE performance, the contribution of the review course was limited to 1.5 percent. The review course was most effective in areas that (1) were covered during the greatest number of terms, (2) were presented most recently, or (3) had the least number of topics on the NBE. This strategy for evaluating course effectiveness permits a dental school to easily assess the value of an NBE review course, as well as identify strengths and weaknesses in the curriculum.

The academic qualifications and dental school performance measures of students enrolled at public and private dental schools during the five-year period beginning in 1980 were examined. The results indicated that mean DAT academic averages and predental science GPA measures declined significantly over the most recent four years observed. For these qualifications, there were significant differences between those students enrolled at public and private dental schools, with those students enrolled at public schools tending to outperform those at private schools. The results of the analyses of dental school performance measures showed no clear, consistent pattern of decline over the same five-year period.

Recent studies of the Embedded Figures and Mirror-Tracing Tests as predictors of first-, second-, and third-year dental students' grades were extended to the fourth year, and the comparative utility of the experimental predictors were examined in groups of recent dental graduates categorized by their predental science GPAs and DAT scores. The experimental predictors proved to very strong in graduates whose grades were below average at admission and were the best overall predictors for students who entered dental school with a predental science GPA below 3.0 or a combined DAT score below 4.0. Neither the DATs nor the predental science GPAs contributed consistently as predictors in these below average students. However, the predental science GPA was the best single overall predictor for all graduates (when not categorized as described). the experimental predictors contributed significantly to the predictive utility of the predental science GPA.

The purpose of this study was to determine the predictive validity of preadmission scores on the performance of 131 students from nine successive classes at the Harvard School of Dental Medicine. The predictors included high school rank, SAT Verbal and Quantitative, selectivity of undergraduate college, college GPA, and DAT Academic, and PAT averages. The performance scores included science GPA, clinical GPA, oral examination scores, and scores on Parts I and II of the dental National Board examinations. Correlation coefficients were calculated between each predictor and performance measure. Only one was significantly greater than zero: DAT Academic average was positively related to Part II Board scores (r = .29). The apparent lack of validity of the other predictors was attributed to their restricted range.

Students contorted to achieve direct vision indicate that training of mirror skills is absent or ineffective. Training referenced in the literature is not described or amounts to practice using a mirror to perform a psychomotor task often marginally related to dental procedures. No complete task analysis of mirror use is reported. In this study, the authors applied instructional engineering principles to 1) analyze the task and design instruction, 2) validate instruction, and 3) foster mirror use. First-year students (experimentals) completed the new mirror instruction as well as the regular course instruction. A randomly selected group of second-year students who had not completed the mirror instruction but had completed a similar course comprised the control group for the validation. Sets of randomly grouped experimental subjects evaluated a maxillary preparation using mirror vision at three times during the semester and one time a year later. The controls evaluated the same preparation the first time only. Accuracy in describing the critical features of the preparation was used as an indicator of mirror skill. All subjects were observed for mirror use during a practical examination involving maxillary preparations. All groups were equivalent on entering GPA, DAT-A, and DAT-P. Experimental groups made significant improvement in measures of mirror vision skill over time. Experimental groups 2, 3, and 4 significantly outperformed controls on the same measures and demonstrated significantly higher rate of mirror use during the practical exam. The mirror skills instruction appears valid.

DAT scores and predental GPAs have made the greatest but an imperfect contribution to the reliable estimation of dental students' academic success. One variable unaddressed yet having potential in accounting for unexplained variability in dental school performance is time management behaviors (TMB), a multidimensional attribute that is critical to success in a dental curriculum. Research has indicated a relationship of TMB dimensions (Setting Goals and Priorities, Mechanics of Time Management, Preference for Organization) with undergraduate academic achievement. The purposes of this study were: 1) to ascertain the levels of TMB dimensions reflected in predental students; 2) to validate in predental students the relationship of TMB dimensions and undergraduate academic achievement; and 3) to explore the relationship of TMB dimensions of predental students as explanatory variables of their early academic achievement in the dental curriculum. All individuals who were applicants interviewed for the 1997 entering D.D.S. class and the majority of members of the 1996 entering D.D.S. class participated in this study (n = 192). Each completed the TMB scale. High levels of TMB across dimensions were observed in predental and dental students. Unlike prior research, results showed virtually no relationship of TMB dimensions with undergraduate GPA of these subjects. Though a small relationship was found between dimensions and first-year dental GPAs, no dimension explained a significant amount of variance in any of these dental GPAs beyond that of undergraduate science GPA.

There were 7,770 applicants to the entering dental school class of 2000. This is almost 14 percent less than the number of applicants to the entering class of 1999. Since the peak of dental school applicants in 1997 (at 9,829), the number has declined 21 percent. (This is most similar to the decline that has occurred in medical school applicants since their peak of applicants in 1996, at 46,968.) Almost 55 percent of the applicants to dental school were enrolled in 2000. Dental schools reported 4,234 first-time, first-year enrollees in 2000. This is an increase of 25 enrollees over the number reported in 1999. Since 1989, when dental school enrollment once again began to increase, total first-year dental school enrollment has increased 8.7 percent. The number of applicants per first-time, first-year position was 1.84 in 2000. It was 2.14 in 1999. (The most recent low was 1.34 in 1989.) The GPA and DAT scores of the first-time, first-year enrollees in 2000 were all either equal to or slightly higher than they were in 1999. Women were approximately 40 percent of the applicants and first-time, first-year enrollees in 2000, up slightly from 1999. Underrepresented minorities comprised slightly over 12 percent of the applicants and 10.6 percent of the first-time, first-year enrollees, also up slightly from 1999.

There were 7,412 applicants to the entering dental school class of 2001. This is 4.6 percent less than the number of applicants to the entering class of 2000. Since the peak of dental school applicants in 1997 (at 9,829), the number of applicants has declined 24.6 percent. (This decline is most similar to the 25.8 percent decline that has occurred in medical school applicants since their peak of applicants in 1996, at 46,968.) With the decline in applicants and a slight increase in first-time, first-year enrollees, 57.6 percent of the dental school applicants were enrolled in 2001. This is up from 54.5 percent in 2000. Dental schools reported 4,267 first-time, first-year enrollees in 2001. This is an increase of thirty-three first-time, first-year enrollees over the number reported in 2000 and only an increase of fifty-eight over the last two years. Since 1989, when dental school enrollment once again began to increase, the number of first-time, first-year enrollees has increased 14.9 percent. (Total first-year enrollment, which includes first-time enrollees and repeat students, has increased 10.8 percent since 1989.) The number of applicants per first-time, first-year positions was 1.74 in 2001. It was 2.31 in 1997. (The most recent low was 1.34 in 1989.) The average of the GPA and DAT scores of the first-time, first-year enrollees in 2001 were all slightly higher than they were in 2000. Women were approximately 42 percent of the applicants and first-time, first-year enrollees in 2001, up slightly from 2000. Underrepresented minorities comprised over 12.6 percent of the applicants and 11.9 percent of the first-time, first-year enrollees, also up slightly from 2000.

In 2002, there were 7,537 applicants to all entering dental school classes in the United States. This represents a 1.7 percent increase over the number of applicants in 2001. Between the peak of applicants in 1997 (at 9,829) and 2001, the number declined 25.0 percent. (This is similar to the percent decline that occurred in medical school applicants since their peak in 1996, at 46,968.) Dental schools reported 4,372 first-time, first-year enrollees in 2002. This is an increase of 105 first-time, first-year enrollees over the number reported in 2001. With the 1.7 percent increase in applicants and the 2.5 percent increase in first-time, first-year enrollees over last year, 58 percent of the dental school applicants were enrolled in 2002. This is up very slightly from 57.6 percent in 2001. Since 1989 when dental school enrollment once again began to increase, the number of first-time, first-year enrollees has increased 17.7 percent. (Total first-year enrollment, which includes first-time enrollees and repeat students, has increased 11.8 percent since 1989.) The number of applicants per first-time, first-year position was 1.72 in 2002. It was 2.31 in 1997. (The most recent low was 1.34 in 1989.) The average GPA and DAT scores of first-time, first-year enrollees in 2002 were essentially unchanged from what they were in 2001. Women were 43.7 percent of the applicants and 42.7 percent of first-time, first-year enrollees in 2002, slight increases from what they were in 2001. Underrepresented minorities comprised 12.8 percent of the applicants and 11.4 percent of the first-time, first-year enrollees in 2002. These percentages are little changed from those reported in 2001.
