Objective: This retrospective study was conducted to investigate whether medical students have ever bandaged patients' limbs, whether they feel confident in their ability to bandage, and whether their bandaging skills are adequate.Methods: The study included consecutive fifth-year medical students who had not been taught bandaging knowledge and skills. In total, 232 students (163 men, 69 women) participated in the study. Prior to the practical session, the students' experiences and confidence in bandaging were assessed. During the practical, an evaluator assessed the students' bandaging skills, determining the correct application of bandages and assigned a numerical score. Correlations were analyzed using the Chi-square test.Results: Of the medical students in this study, 60% had not bandaged a limb by their fifth year, and 91% lacked confidence in their bandaging ability. Only 32% of students could correctly apply a bandage with a perfect score. No significant relationships were identified between experience and bandaging skill (P = 0.64) or confidence and bandaging skill (P = 0.36).Conclusions: Bandages must be applied perfectly to prevent loosening and contamination of the wound. Nevertheless, most medical students had not bandaged a limb, lacked confidence in their bandaging abilities, and were unable to correctly apply a bandage. It is imperative that medical educators teach bandaging skills to medical students and provide ample opportunities for practice.

Purpose: Patients with head and neck cancer (HNC) who undergo dental procedures during radiotherapy (RT) face an increased risk of developing osteoradionecrosis (ORN). Accordingly, new tools must be developed to extract critical information regarding the dose delivered to the teeth and mandible. This article proposes a novel approach for visualizing 3-dimensional planned dose distributions on panoramic reconstruction computed tomography (pCT) images. Materials and Methods: Four patients with HNC who underwent volumetric modulated arc therapy were included. One patient experienced ORN and required the extraction of teeth after RT. In the study approach, the dental arch curve (DAC) was defined using an open-source platform. Subsequently, pCT images and dose distributions were generated based on the new coordinate system. All teeth and mandibles were delineated on both the original CT and pCT images. To evaluate the consistency of dose metrics, the Mann-Whitney U test and Student t-test were employed. Results: A total of 61 teeth and 4 mandibles were evaluated. The correlation coefficient between the 2 methods was 0.999, and no statistically significant difference was observed (P>0.05). This method facilitated a straightforward and intuitive understanding of the delivered dose. In 1 patient, ORN corresponded to the region of the root and the gum receiving a high dosage (approximately 70 Gy). Conclusion The proposed method particularly benefits dentists involved in the management of patients with HNC. It enables the visualization of a 3-dimensional dose distribution in the teeth and mandible on pCT, enhancing the understanding of the dose delivered during RT.
