PurposeThe evaluation of the effectiveness of simulation training in dentistry has previously been focused primarily on psychomotor hand skills. This study explored the impact of simulated patient (SP) encounters in simulation on students’ self‐assessment of competency in their clinical and communication abilities with geriatric patients.MethodsStudents from 2 cohorts were recruited for this study. Cohort 1 (n = 30) participated in the standard curriculum with no simulation training and served as the control group. Cohort 2 (n = 34) participated in a SP experience, simulating the initial stages of a care visit for 2 nursing home patients. Students’ perceptions of competency to perform these clinical and communication tasks were assessed. A group debriefing session was held 5 weeks post‐simulation where Cohort 2 completed a student feedback form.ResultsA statistically significant change (P < 0.00001) was noted for both cohorts in their self‐reported competence to perform clinical tasks following exposure to an independent clinical experience. In addition to this gain, individuals in Cohort 2 demonstrated improvements following simulation and expressed different responses of impact to questions related to treatment, pharmacology, and managing a complex medical history.ConclusionsThis study suggests that simulation of patient interactions using SPs can strengthen students’ self‐assessment of competency in their abilities, leading to more genuine interactions with actual patients. These findings will help inform the design of future SP encounters as a component of an evolving humanistic curriculum.
