An Ellis Class IV crown fracture
1. does not involve the pulp
2. is so extensive that the entire crown has been lost
3. involves only the enamel
4. may expose the pulp
Pedodontics
Answer: 2
An Ellis Class IV crown fracture is characterized by the loss of a significant portion of the crown, often such that the pulp may be exposed. This severe type of fracture requires immediate attention to prevent further damage to the tooth
Ellis Class IV fractures are the most severe form of crown fractures. They extend below the gingival margin and involve the enamel, dentin, and often the pulp. The pulp may be exposed, making it a dental emergency.
