Case of the Week: Coronal fracture

This week I decided to showcase a case of coronal (crown) fracture associated with a posterior tooth.  Coronal fractures are more commonly associated with anterior teeth, specifically the maxillary incisors.  This case was a cusp fracture of a maxillary premolar with the other cusp still present.  There is a sharp line evident (noted with arrows) where the cusp fractured off.  Due to the one cusp no longer being present this creates an overall more radiolucent crown compared to the teeth adjacent to the premolar.  Check it out and let me know if you have any questions.
