What is the first line of treatment for a horizontal root fracture?

splint, coronal > apical
apexogenesis
pulpotomy
splint, apical > coronal

The correct answer is: splint, coronal > apical

Horizontal root fractures occur primarily in anterior teeth and can involve the pulp or pulpal elements. The first line of treatment is to splint the tooth with a flexible splint, in a coronal to apical direction. This allows for proper stabilization and reduces the risk of further damage to the root. Other options such as apexogenesis (promoting root development) and pulpotomy (partial removal of pulp tissue) are not the primary treatment for a horizontal root fracture. Additionally, splinting the tooth in an apical to coronal direction can lead to further damage and should be avoided.
