Objective: To evaluate the potential use of digital and reconstructed three-dimensional printed models as an alternative to conventional plaster models by assessing the accuracy of their linear measurements. Methodology: Pre-treatment plaster models of 45 patients were selected from the archives of the Department of Orthodontics. Each physical plaster model was scanned and digitized using a three-dimensional (3D) laser surface scanning system (inEOS X5, Dentsply Sirona, Bensheim, Germany). The scanned STL files were later used to reconstruct models by 3D printing using Figure4® standalone 3D printer (3D systems, Rock Hill, South Carolina). Measurements of teeth 11 and 16, the transverse width of the upper jaw between the first molars (MM - intermolar width) and canines (CC - intercanine width) were done manually using a digital vernier caliper (Mitutoyo, Kawasaki, Japan), and the CAD Assistant software (Open cascade, Guyancourt, France). Intra examiner data, Intraobserver variability, and measurement accuracy were evaluated using Intraclass Correlation Coefficient (ICC) analysis was done using SPSS 20.0. Results: The intraclass correlation coefficients were >0.8 indicating high reproducibility and reliability. Significant differences were found between the physical and the digital models but to a small proportion which were deemed not clinically relevant. Conclusion: Both the digital models and reconstructed three-dimensional printed models using Figure4® technology were clinically permissible in terms of accuracy and reproducibility. The digital storage, transmission, and treatment planning in an environmentally friendly manner should promote digital over conventional records.

Introduction: Leadership skills among medical students, plays an important role in making them competent and bringing success in their clinical practice. Physician’s professional activities require them to be good team leaders. But there is a leadership crisis among medical doctors in India and leadership skills within their curricula. Objectives: To assess the leadership skills among interns and identify possible influencing factors among them. Method: A cross sectional study was conducted among 110 interns in a medical college. Leadership skills were assessed using Modified Leadership Inventory for Medical Education (LIME). Unpaired t test for association of various factors with mean scores of leadership and Karl Pearson’s correlation coefficient for correlation between the scores of subcomponents of leadership skills were used. Results: Among the interns, 77.3% had a chance to be a leader during school/college days but only 20% had undergone leadership training. 87.3% of them had their leadership scores above average, suggesting good leadership skills. Interns who had been a leader in school/college, enrolled in Scouts/ Guides/ NCC and those who underwent leadership training had statistically significant higher mean scores. Majority had positive attitude towards leadership. There was a statistically significant, moderate correlation between the components of leadership skills.Conclusion: Participants had good leadership skills and there was significant association between former leadership experience and current leadership scores. Most of them had positive attitude towards leadership.
