Which type of root fracture is more commonly observed?

Traumatic forces on a tooth often come in at an angle, causing the root to bend and shear rather than split straight across. This combination tends to create a fracture line that runs diagonally through the root, so oblique fractures are seen most often, typically in the middle third where bending stresses concentrate. Horizontal fractures require a very specific load direction and are less common, and vertical fractures usually arise in teeth with predisposing factors or where the force persists along the long axis. So the oblique pattern best matches the usual traumatic load and the tooth’s response, making it the pattern you’re most likely to encounter.
