Gender equity in The Journal of the American Dental Association: A review of the past 2 plus decades.

BACKGROUND: Considering evidence of closing the gender gap in dental scholarship, this study assessed women's participation as authors, reviewers, and members of the editorial board for The Journal of the American Dental Association (JADA) from 2000 through 2022. METHODS: The study authors downloaded author names from PubMed and retrieved names of reviewers and editorial board members from JADA's pages. The authors used Gender-API software to determine gender on the basis of first names. They used logistic regression to test for trends. RESULTS: From January 2000 through December 2022, there were 2,935 full-length articles, 2,775 reviewers, 4 editors in chief, and 85 editorial board members. The percentage of women authors increased by 1.2% annually (95% CI, 1.03% to 1.33%), reaching 47% in 2022. First authorship increased by 2.1% annually (95% CI, 1.84% to 2.39%) and has been at more than 50% since 2016. In articles with multiple authors, there was a modest increase; second authorship increased 0.7% annually (95% CI, 0.36% to 1.09%) and last authorship by 0.7% (95% CI, 0.03% to 1.00%). Women reviewers increased 0.8% annually (95% CI, 0.68% to 0.97%), but the percentage of women on the editorial board did not increase significantly and was 41% in 2022. CONCLUSIONS: It was anticipated that 50% of JADA authors would be women by 2024. However, women are still underrepresented on the editorial board. A comprehensive effort is needed to foster role models, provide mentorship opportunities for women, and support women's professional advancement in dental research and publications. PRACTICAL IMPLICATIONS: Gender-based disparities affect women in dental education and clinical practice. Serving as an editorial board member, reviewer, or author can affect academic promotion and the type of scientific investigation being conducted and indirectly affects women's health outcomes.

Practice makes perfect? Association between students' performance measures in an advanced dental simulation course.

PURPOSE: This study examines the relationship between student performance measures during practice and exams using advanced dental simulation. METHODS: Data from 11 classes of first-year dental students were extracted from Advanced Simulation software (DentSim™) related to Class I and Class II preparations including: total number of practice sessions, average practice score, exam scores, average time preparing teeth during practice/exam, and average time self-evaluating preparations during practice/exam. Comparisons of average practice and exam scores were examined using paired t-test. Relationships between practice/exam measures and exam scores were determined with multiple linear regression. RESULTS: Practice mean and exam scores were significantly associated; exam scores were significantly higher in both procedures. Class I: a significant positive relationship exists between both practice and exam measures: The average practice score was significantly associated with exam score (p < 0.001); time spent preparing the exam tooth was negatively associated with the exam score (p < 0.001); conversely, time spent self-evaluating the exam tooth was significantly associated with an increase in exam score (p = 0.0135). Class II: exam score was significantly associated with two practice measures but neither of the exam measures: exam score for Class II mesioocclusal preparation was significantly associated with average practice score (p < 0.001) and the number of practice attempts (p = 0.025). CONCLUSION: This study emphasizes the predictive value of novice learners' deliberate, repetitive practice using advanced dental simulation, which enhances self-assessment in early stages of psychomotor skill development. Future studies are needed to demonstrate the translation of these skills into a patient care setting.

Transitioning into an online dental hygiene degree-completion program.

PURPOSE: The University of British Columbia's (UBC) Dental Hygiene Degree-Completion (DC) program has offered an academic pathway for dental hygienists to earn a degree exclusively through an online delivery format since 2006. The students' experiences transitioning to online learning and related student support needs have not been previously studied. Thus, this study investigated students' experiences as they entered an online dental hygiene DC program METHODS: An online survey with open-ended and closed-ended questions was distributed to all 53 currently enrolled dental hygiene DC students in September 2019 RESULTS: Thirty-two students completed the survey for a 60% response rate. Most student respondents (78%) had no prior experience with online education. Only 59% of respondents were confident in their abilities to navigate a Web-based learning environment. Three-quarters (75%) of respondents felt like a valued member of the Faculty of Dentistry community but only 47% felt they belonged to the larger university community. Most (72%) were familiar with the support resources within the Faculty but fewer than half (41%) were aware of additional resources outside of the Faculty. Students aged 30 years and older felt more comfortable reaching out to faculty and staff members (90% vs. 55%; P = 0.05). Students with prior online learning experience were more aware of student support resources outside of the Faculty (57% vs. 36%; P = 0.05) CONCLUSION: Lessons learned from this study have informed several recommendations to better support student transition to online learning that can be applicable to this program and in other institutions.

Should the U.S. Adopt a National Dental Clinical Licensure Examination? Two Viewpoints: Viewpoint 1: National Licensure Would Provide Multiple Advantages for Practitioners and the Profession and Viewpoint 2: Licensing Authority Should Remain Under State Dental Boards' Jurisdiction.

This Point/Counterpoint article examines the need for and potential impact of implementing a national clinical examination for initial licensure in dentistry. Viewpoint 1 supports a national licensure exam that meets the clinical exam's credentialing requirement for licensure in every state. According to this viewpoint, a national exam will reduce costs, enhance portability of graduates, simplify the transition from dental school to practice or specialty training programs, and standardize requirements for licensure between states. Viewpoint 2 opposes a national licensure exam. This viewpoint supports individual states' dental board decision making process, which is based on identifiable state-specific criteria. The ability to prioritize needs at the state level allows for higher exam standards, easier modifications, more focused requirements, and better calibration in specific exam areas. Viewpoint 2 argues that the delicate balance between licensure agencies and organized dentistry in each state, as well as the involvement of dental schools in the licensure process, must be preserved. This Point/Counterpoint concludes with a joint statement about the prospects for adoption of a national licensure exam.

Predicting Performance in Technical Preclinical Dental Courses Using Advanced Simulation.

The aim of this study was to investigate whether advanced simulation parameters, such as simulation exam scores, number of student self-evaluations, time to complete the simulation, and time to complete self-evaluations, served as predictors of dental students' preclinical performance. Students from three consecutive classes (n=282) at one U.S. dental school completed advanced simulation training and exams within the first four months of their dental curriculum. The students then completed conventional preclinical instruction and exams in operative dentistry (OD) and fixed prosthodontics (FP) courses, taken during the first and second years of dental school, respectively. Two advanced simulation exam scores (ASES1 and ASES2) were tested as predictors of performance in the two preclinical courses based on final course grades. ASES1 and ASES2 were found to be predictors of OD and FP preclinical course grades. Other advanced simulation parameters were not significantly related to grades in the preclinical courses. These results highlight the value of an early psychomotor skills assessment in dentistry. Advanced simulation scores may allow early intervention in students' learning process and assist in efficient allocation of resources such as faculty coverage and tutor assignment.

An automated dental caries detection and scoring system for optical images of tooth occlusal surface.

Dental caries are one of the most prevalent chronic diseases. The management of dental caries demands detection of carious lesions at early stages. This study aims to design an automated system to detect and score caries lesions based on optical images of the occlusal tooth surface according to the International Caries Detection and Assessment System (ICDAS) guidelines. The system detects the tooth boundaries and irregular regions, and extracts 77 features from each image. These features include statistical measures of color space, grayscale image, as well as Wavelet Transform and Fourier Transform based features. Used in this study were 88 occlusal surface photographs of extracted teeth examined and scored by ICDAS experts. Seven ICDAS codes which show the different stages in caries development were collapsed into three classes: score 0, scores 1 and 2, and scores 3 to 6. The system shows accuracy of 86.3%, specificity of 91.7%, and sensitivity of 83.0% in ten-fold cross validation in classification of the tooth images. While the system needs further improvement and validation using larger datasets, it presents promising potential for clinical diagnostics with high accuracy and minimal cost. This is a notable advantage over existing systems requiring expensive imaging and external hardware.

Faculty impressions of dental students' performance with and without virtual reality simulation.

This study compared faculty perceptions and expectations of dental students' abilities using virtual reality simulation (VRS) to those who did not use virtual reality simulation (non-VRS) in an operative dentistry preclinical course. A sixteen-item survey with a ten-point rating scale and three open-ended questions asked about students' abilities in ergonomics, confidence level, performance, preparation, and self-assessment. The surveys were administered three times to a small group of preclinical faculty members. First, faculty members (n=12, 92 percent response rate) gave their perceptions of non-VRS students' abilities at the end of their traditional course. Secondly, faculty members (n=13, 100 percent response rate) gave their expectations of the next incoming class's abilities (VRS students) prior to the start of the course with traditional and VRS components. Finally, faculty members (n=13, 100 percent response rate) gave their perceptions of VRS students' abilities after completion of the course. A Tukey's test for multiple comparisons measured significance among survey items. Faculty perceptions of VRS students' abilities were higher than for non-VRS students for most abilities examined. However, the faculty members' expectations of VRS training were higher than their perceptions of the students' abilities after VRS training for most abilities examined. Since ergonomic development and technical performance were positively impacted by VRS training, these results support the use of VRS in a preclinical dental curriculum.
