Identifying factors influencing orthodontic residency program selection

PURPOSE

The desirability of Orthodontic Residency remains high today relative to the past 30 years. This investigation seeks to re-assess factors influencing Orthodontic Residency program selection amidst contemporary challenges and changes, including increasing student debt, reduced residency stipends, and shifting practice models.

METHODS

This mixed-methods study consisted of interviews (qualitative) and surveys (quantitative). Fifteen final-year dental students and first-year orthodontic residents were interviewed one-on-one following a topic guide and then transcripts were analyzed using MAXQDA2022 to identify values, factors, and influences related to program selection and ranking. Qualitative findings and previous studies provided the basis for a survey distributed to residency applicants in 2020-22. Data were analyzed with bivariate and descriptive statistics with stratification by debt group.

RESULTS

Interviews (N = 15) elevated the importance of location, interview experience, program cost, and clinical education. Surveys (N = 239) identified the most desirable factors for program selection: satisfied residents, strong clinical training with multiple techniques, good interview impressions, low cost, high patient numbers, a strong reputation, and good clinical facilities with new technology. Less desirable factors include programs that are hospital-based, certificate-only, research-intensive, and require considerable after-hours work.

CONCLUSIONS

Clinical education and interview experiences are key for residency selection, consistent with prior studies, though program cost has grown in importance. Findings can help guide orthodontic programs in recruiting applicants and suggest a need to limit educational costs.

Evaluating video-based lectures on YouTube for dental education

PURPOSE/OBJECTIVES

Multimedia presentations and online platforms are used in dental education. Though studies indicate the benefits of video-based lectures (VBLs), data regarding user reception and optimal video features in dental education are limited, particularly on Web 2.0 platforms like YouTube. Given increasing technology integration and remote learning, dental educators need evidence to guide implementation of YouTube videos as a freely available resource. The purpose of this study is to determine video metrics, viewership and format efficacy for dental education videos.

METHODS

First, a cross-sectional survey was conducted of viewers (N = 683) of the Mental Dental educational videos on YouTube. Analytics were evaluated for 677 200 viewers to assess audience demographics, retention and optimal video length. Second, a randomized crossover study was conducted of dental students (N = 101) who watched VBLs in either slideshow or pencast formats and were tested on content learning to compare format efficacy.

RESULTS

Most viewers of Mental Dental videos were dental students (44.2%) and professionals (37.8%) who would likely recommend the platform to a friend or colleague (Net Promoter Score = 82.1). Audience retention declined steadily at 1.34% per minute, independent of video length. Quiz performance did not differ between slideshow and pencast videos, with students having a slight preference for slideshows (P = 0.049).

CONCLUSIONS

Dental students and professionals use VBLs and are likely to recommend them to friends and colleagues. There is no optimal video length to maximize audience retention and lecture format (slideshow vs. pencast) does not significantly impact content learning. Results can guide implementation of VBLs in dental curricula.
