The most important factor for the long term success of the restoration of an endodontically treated tooth is:

Type of filling material
Absence of post
Presence of extracoronal coverage
Root canal sealing quality

The correct answer is: Presence of extracoronal coverage

A restoration with extracoronal coverage is the most important factor for the long term success of an endodontically treated tooth because it helps protect the tooth from further damage and contamination. Options A and D may contribute to the success of the restoration, but without proper coverage, the tooth is still at risk. Option B is incorrect because the absence of a post does not necessarily determine the success of the treatment, only the stability of the restoration.
