The restoration of endodontically treated teeth is an area of much controversy and divergence of opinions. Is the pulpless tooth more susceptible to fracture than a tooth with pulp? Does every en­ dodontically treated tooth require a post and core? Does a dowel and core protect the tooth from frac­ ture? Is a cast post superior to a prefabricated post in protecting the tooth against fracture potentials?

In answering these questions, the dentist often depends on his own clinical experience and past training.
