Answer: A - A sulcular hemorrhage is seen in subluxation tooth trauma. There is an injury to supporting structures with loosening of the tooth, but not displacement. If subluxation affects the primary teeth, observe for infection, and expect tooth normalcy within two weeks. If permanent teeth are affected, the tooth may need stabilization and occlusal enameloplasty. In this case, there is a high percentage of pulpal necrosis.
