Purpose The entrustable professional activity (EPA) framework is an assessment approach used to define the educational outcomes of a program by outlining discrete work tasks learners are expected to perform independently upon graduation. This study outlines the development and evaluation of an EPA framework for predoctoral dental education at the University of North Carolina Adams School of Dentistry. Methods The draft EPA framework was created in collaboration with a group of faculty members and included 15 statements that were mapped to relevant Commission on Dental Accreditation standards. The draft EPA framework was distributed to faculty via an electronic survey, requesting participants to evaluate whether the EPAs were well‐defined; observable; measurable; expected of a general dentist; transferable to other practice settings; and required application of relevant knowledge, skills, and attitudes. In addition, participants were asked to identify the percentage of graduates who could perform these tasks independently and whether learners must be able to perform the list of EPAs upon graduation. Results Sixty‐eight faculty members completed the survey (72% response rate); participants represented all divisions across the school and had extensive dental practice experiences. Overall, participants agreed the EPAs met the defined criteria and were considered important for graduates to be able to demonstrate. Feedback from faculty voiced support for the EPA framework and identified concerns regarding the implementation due to potential faculty calibration and time constraints. Conclusion Evidence from this study supports additional research to explore how the EPA framework can be further developed in predoctoral and postgraduate dental education programs.
Purpose: Technological advancements in dental radiography have improved oral care on many fronts, yet diagnostic efficacy for some of the most common oral conditions, such as caries, dental cracks and fractures, and periodontal disease, remains relatively low. Driven by the clinical need for a better diagnostic yield for these and other dental conditions, we initiated the development of a stationary intraoral tomosynthesis (s-IOT) imaging system using carbon nanotube (CNT) x-ray source array technology. Here, we report the system characterization and preliminary imaging evaluation of a clinical prototype s-IOT system approved for human use. Methods: The clinical prototype s-IOT system is comprised of a multi-beam CNT x-ray source array, high voltage generator, control electronics, collimator cone, and dynamic digital intraoral detector. During a tomosynthesis scan, each x-ray source is operated sequentially at fixed, nominal tube current of 7mA and user-specified pulse width. Images are acquired by a digital intraoral detector and the reconstruction algorithm generates slice information in real time for operator review. In this study, the s-IOT system was characterized for tube output, dosimetry, and spatial resolution. Manufacturer specifications were validated, such as tube current, kVp, and pulse width. Tube current was measured with an oscilloscope on the analog output of the anode power supply. Pulse width, kVp, and peak skin dose were measured with a dosimeter with ion chamber and high voltage accessory. In-plane spatial resolution was evaluated via measurement of MTF and imaging of a line pair phantom. Spatial resolution in the depth direction was evaluated via artifact spread measurement. The size of the collimated radiation field was evaluated for compliance with FDA regulations. A dental phantom and human specimens of varying pathologies were imaged on a clinical 2D intraoral imaging system as well as s-IOT for comparison and to explore potential clinical applications. Results: The measured tube current, kVp, and pulse width values were within 3% of the set values. A cumulative peak skin dose of 1.12mGy was measured for one complete tomosynthesis scan using a 50ms pulse per projection view. Projection images and reconstruction slices revealed MTF values ranging from 8.1 to 9.3 cycles/mm. Line pair imaging verified this result. The radiation field was found to meet the FDA requirements for intraoral imaging devices. Tomosynthesis reconstruction slice images of the dental phantom and human specimens provided depth resolution, allowing visibility of anatomical features that cannot be seen in the 2D intraoral images. Conclusions: The clinical prototype s-IOT device was evaluated and found to meet all manufacturer specifications. Though the system capability is higher, initial investigations are targeting a low-dose range comparable to a single 2D radiograph. Preliminary studies indicated that s-IOT provides increased image quality and feature conspicuity at a dose comparable to a single 2D intraoral ...
Following the adoption of competency-based education in dentistry in the 1990s, entrustable professional activities (EPAs) were introduced in the field of medicine in the mid-2000s to help educators better determine the competence of trainees. More recently, the field of dental education has begun exploring EPAs as a framework for assessing competence while ensuring compliance with accreditation standards. This paper explores one dental school's process of preparing for implementation of a major curriculum change using an EPA assessment framework, shifting away from the use of singular assessments for competency determination to a global and longitudinal approach using a constellation of data to determine practice readiness. This paper describes how the EPA framework was developed, including the complementary capacities, assessment tool development and programming, and data reporting to follow learner progression and determine practice readiness. We discuss lessons learned leading up to implementation, and we position this perspective as a space to describe opportunities and complexities to consider when using a
Objectives: This study examined the utility of stationary intraoral tomosynthesis (s-IOT) in opening proximal contacts in bitewing radiography. Methods: 11 DENTSPLY Rinn Dental X-ray Teaching and Training Replica mannequins (Model #546002, Elgin, Ill) were imaged with a prototype s-IOT device (Surround Medical Systems, Morrisville, NC) and standard bitewing (SBW) technique. Premolar and molar bitewings were acquired with each system. Image receptor holders were used to position receptors and aid in the alignment of the position indicating devices. An expert operator (having more than 5 years of experience in intraoral radiography) acquired the images with the s-IOT prototype and standard intraoral X-ray devices. Images were assessed to analyze percentage overlap of the proximal surfaces using the tools available in ImageJ (NIH, Bethesda Maryland). Results: 253-paired surfaces were included in the analysis. The difference in overlap was statistically significant with standard bitewing (SBW) images resulting in a median overlap of 13%, a minimum of 0%, a maximum of 100% and an interquartile range of 40%. s-IOT resulted in a median overlap of 1%, a minimum of 0%, a maximum of 37% and an interquartile range of 0%. The s-IOT prototype substantially reduced proximal surface overlap compared to conventional bitewing radiography. Conclusions: The use of s-IOT reduced proximal contact overlap compared to standard bitewing radiography for an experienced radiographer. Stationary intraoral tomosynthesis may be a potential alternative to SBW radiography, reducing the number of retakes due to closed contacts.
