Development and evaluation of a dental hygiene education program using scenario-based simulation method.

BACKGROUND/PURPOSE: Scenario-based simulation education has been increasingly used in health professions to enhance clinical competence. However, its application in dental hygiene education remains limited. This study aimed to develop and evaluate a scenario-based simulation program focusing on oral care for elderly patients with systemic diseases to foster clinical skills. MATERIALS AND METHODS: Participants were four fourth-year students and ten graduates from a dental hygiene course who completed a two-day session: the initial session and a follow-up session three months later. During the initial session, participants conducted the first practice, followed by debriefing and a second practice. Clinical skills were evaluated using an original 25-item checklist (maximum score: 47 points). Self-confidence was assessed using a 12-item questionnaire rated on a 10-point Likert scale at four time points: before and after each session. Changes in skills and confidence throughout the program were statistically analyzed. RESULTS: The median (interquartile range: IQR) total score of clinical skills significantly increased from 26.0 (24.0-28.3) at the first practice to 38.5 (35.8-40.3) at the second (P < 0.001), and was maintained with 35.5 (33.5-38.3) at follow-up practice. The median (IQR) total confidence scores were 49.5 (38.0-58.8) before and 71.5 (64.0-86.8) after the initial session, and 65.0 (54.0-72.3) before and 80.5 (74.3-87.5) after the follow-up session, indicating significant improvements through both sessions (P < 0.01). CONCLUSION: Scenario-based simulation education significantly enhanced clinical skills and confidence in oral care for elderly patients with systemic diseases, suggesting its educational value in dental hygiene education.
