For a horizontal root fracture, which is better, coronal or apical?

  1. coronal

  2. apical

  3. neither

  4. depends on the situation

The correct answer is: apical

A horizontal root fracture requires prompt dental care in order to avoid serious damage and potential tooth loss. With a horizontal root fracture, the tooth is cracked from one side of the root to the other. In this case, an apical approach is better as it involves repositioning and stabilizing the root fragment from the bottom of the tooth. A coronal approach involves repositioning from the top of the tooth and may not provide enough stability for the fractured root. The options of "neither" and "depends on the situation" are incorrect since an apical approach is generally the preferred method for treating a horizontal root fracture.
