This week I have a case of a vertical root fracture where there is no separation of the two segments. This case shows a radiolucent area on the mesial aspect of the root and at the apex of the same root. This is sometimes to referred to as a “J” shaped radiolucent lesion that is a characteristic sign of a vertical root fracture. When evaluating clinically for a root fracture it is important to probe carefully around the tooth. Typically these cases will have normal probing depths (2-3 mm) everywhere except for in one spot where the probe will drop down to 8 mm or more indicating bone loss in just that specific location.
