摘要：Recent advancements in zirconia based restorations extended the survival rate of fixed dental prosthesis and single crown to the next level. Both Monolithic and layered zirconia are highly preferred among prosthodontists for both anterior and posterior edentulous areas. Hence the assessment of differences between monolithic and hand layered crowns among dental students is significant to provide a high quality rehabilitation to the patients. To assess the knowledge and awareness of the difference between monolithic and hand layered zirconia crowns among dental students. Materials and methods: A total of 150 dental undergraduate students aged between 18-25 years were included in this study. A questionnaire based online survey was conducted using the link created in google forms. The responses were tabulated in excel sheets and imported to Statistical Package of Social Sciences version 17, IBM corporation. Results: 68% of the students are aware that the monolithic crown has higher restoration strength than the hand layered crown. 82% of the dental students are aware that hand layered crowns have outstanding biocompatibility in the oral cavity. 76.6% of them are aware that hand layered zirconia has a superior aesthetic level. About 91.3% were aware that a hand layered crown is preferred for replacement of anterior teeth. 76.6% are aware that hand layered zirconia has more translucency and opalescence than monolithic zirconia. The percentage of knowledge and awareness was higher among intern students compared to third and fourth year undergraduate students (Significant association; chi square test- p<0.001). Conclusion: The awareness of the difference between monolithic and hand layered crowns is not adequate among dental students.
