Sodium Hypochlorite Awareness and Irrigation Safety Among Dental Students: A Cross-Sectional Study

Abstract

Objectives This study aimed to develop, psychometrically refine, and validate a scale assessing undergraduate dental students’ perceived preparedness for preventing, recognizing, and managing sodium hypochlorite (NaOCl) accidents across pre-clinical and clinical stages of dental education. Material and Methods In this cross-sectional validation study, 200 undergraduate dental students completed an initial questionnaire on NaOCl irrigation safety. Exploratory factor analysis was performed using principal axis factoring with Direct Oblimin rotation. Internal consistency was assessed using Cronbach’s alpha. Since scale scores were not normally distributed, between-group comparisons were conducted using non-parametric tests. Results The refined 15-item scale showed strong psychometric performance. Exploratory factor analysis supported a three-factor structure, explaining 64.51% of the total variance. The scale demonstrated excellent internal consistency, with a Cronbach’s alpha value of 0.934. The mean total preparedness score was 60.58 ± 10.86 out of 75. Preparedness scores differed significantly according to academic year, increasing from the second to the fifth year. However, no significant difference was observed between fourth- and fifth-year students. Gender was not significantly associated with preparedness scores. Conclusion The 15-item scale is a reliable and construct-valid instrument for evaluating self-reported preparedness regarding NaOCl irrigation safety. The increase in preparedness across academic years suggests that students’ confidence and perceived competence improve with educational progression. However, the remaining variability in scores indicates the need for earlier, longitudinal, and scenario-based reinforcement of NaOCl accident prevention and emergency management within undergraduate dental curricula.
