An assessment of the efficacy of clinical skills simulation using standardized patient in teaching behavior management and modification skills in Pediatric Dentistry to dental undergraduate students: A double-blinded, randomized, controlled trial

Abstract

Background: Clinical skills simulation (CSS) is an important tool in teaching and learning. The literature review showed a scarcity of research data regarding the use of CSS,in teaching, especially in dentistry. The use of CSS in dental teaching was found restricted to the use of low fidelity typhodonts fitted to phantom heads used in teaching cavity preparation and crown cutting. Aim: The aim of the study was to determine the efficacy of CSS using standardized patient in teaching behavior management and modification skills to dental undergraduate students. Settings and Design: This double-blinded, randomized controlled trial was undertaken among 3rd year dental undergraduate students, and the study was undertaken at the Department of Pediatric and Preventive Dentistry. Materials and Methods: Fifty, 3rd year BDS students were randomly allotted to simulation and nonsimulation groups. Baseline data regarding their knowledge in the behavior management of child patients were assessed. Simulation group was further divided into group of six students and underwent CSS with standardized patient. Pretest and posttest knowledge regarding behavior management was assessed in the simulation group using questionnaires approved by an expert committee. The results were analyzed to see if there is any improvement in their knowledge after CSS. Students in simulation and nonsimulation groups were assessed for their behavior management skills during patient management, by an independent observer, using a checklist. Statistical Analysis: Mean, standard deviation (SD), and unpaired student t-test were done to assess the baseline knowledge of students who participated in the study. Mean, SD, and paired t-test were used to compare the pretest and posttest score of students who underwent simulation. Mean, SD, and unpaired t-test were used to compare the behavior management skills of both groups of students. Results and Conclusions: The knowledge of students in both groups before the study was comparable with no statistically significant differences. There was a statistically significant improvement in the knowledge of students who underwent CSS regarding behavior management of child patients. The unpaired Student's t-test showed a significant difference in the behavior management skill of dental undergraduate students when treating a child patient. The students who underwent CSS fared better compared to students who were taught behavior management methods by traditional methods only. Clinical skill simulation using standardized patient is an effective adjunct to be used along with traditional method of teaching while teaching behavior management and modification skills to dental undergraduate students.
