INBDE (Integrated National Board Dental Examination) 2026 – 400 Free Practice Questions to Pass the Exam

A traumatic dental injury can result in a variety of fractures, with some being more severe than others. An Ellis class IV fracture is the most severe type of dental trauma, as the injury not only affects the enamel, dentin, and pulp, but also leads to the death of the tooth. Options A-C are incorrect as they do not fully describe the severity of the fracture and do not mention the loss of vitality in the tooth. Additionally, options A-C only refer to the physical components of the tooth, while option D provides a more accurate description of the overall damage and impact on the tooth.
