Determining the impact of stressors on students’ clinical performance in endodontics

Abstract

Objectives: This study aims to evaluate the impact of stress on the clinical performance of endodontics dental students. Method: The study sample consists of 16 randomly selected fourth-year dental students who had completed pre-clinical activities stipulated in their curriculum. The distal canal of a plastic mandibular first molar is prepared on two separate occasions, first under normal conditions and then under stressful conditions. The preparation accuracy of the root canal and the time taken to complete the task area measured. Stress is assessed using subjective (State-Trait Anxiety Inventory and Perceived Stress Scale) and objective (heart rate) measures. Results: While the accuracy of the root canal preparation did not differ significantly between the normal and stressful conditions (p > 0.05, paired t-test), the completion time for the root canal preparation decreased significantly under stressful conditions (p < 0.05, paired ttest). Conclusion: The findings of this study suggest that there is no association between the high levels of stress and the performance breakdown of root canal hand instrumentation skills. Students develop an adaptive response to stress, enabling them to improve their completion times and maintain their performance under stressful conditions. Future research should focus on learning methods that can contribute toward better outcomes, especially in stressful environments.
