Perception of students and teachers on the use of simulation in imaging
Abstract
Introduction: Simulation is used to teach and practice radiographic image acquisition through the use of an ideal model or phantom that reproduces the ideal intraoral characteristics of a patient. It utilizes real X-ray equipment, allowing for standardized and repeatable practice. This study aims to understand the perception of learning periapical radiographic image acquisition with a phantom among teachers and students who took imaging courses between 2020 and 2022 at the Universidad Andrés Bello, Viña del Mar campus, Chile.
Material and Methods: An observational, descriptive, quantitative study with a convenience sample of 201 students and 3 teachers. The Barsuk questionnaire was applied to measure learning perception, with 7 questions rated on a 5-point Likert scale, plus a dichotomous question leading to an open-ended question. Data were analyzed with SPSS statistical software, and measures of central tendency, Chi-square, and Z-test (p<0.05) were observed.
Results: Students had a positive perception (p<0.05) regarding useful feedback, the mandatory nature of the phantom practice, and that this experience improves their preparation. The realism of the phantom obtained the lowest mean (2= Disagree). Teachers expressed a positive perception (median= 5) in all statements except for the realism of the phantom (median= 2).
Conclusions: Both students and teachers perceive the use of phantoms for radiographic image acquisition practice positively; therefore, its use is suggested for teaching imaging in dentistry.
