Treatment for extrusion of primary tooth >3mm is:

Reposition, splint 1-2 weeks
Extract
Pulpotomy
No treatment, may damage underlying tooth

The correct answer is: Extract

A Reposition and splinting is typically done when a tooth is dislodged from its original position, but not for extruded teeth. C: Pulpotomy is a procedure performed on a decayed tooth to remove the infected pulp and preserve the remaining healthy tooth structure, but this is not necessary for an extruded primary tooth. D: No treatment may damage the underlying tooth because the extruded tooth can cause pressure and damage the developing permanent tooth underneath. Additionally, leaving an extruded primary tooth untreated can lead to pain and discomfort for the child. Therefore, the best treatment for an extruded primary tooth greater than 3mm would be to extract the tooth. This will prevent any potential complications and allow for proper eruption of the permanent tooth.
