Question 580 · LDEK · Restoration of endodontically treated teeth
Class 3 in the classification system for the restoration of root filled teeth by Żarow et al. requires:
- A. use of a fibre-reinforced composite post for anterior tooth restoration with a coronal tissue loss exceeding 50%.
- B. use of a composite post if the ferrule effect is present.
- C. use of a fibre-reinforced composite following orthodontic crown lengthening.
- D. fabrication of a gold cast post.
- E. tooth extraction.
Hint
The classification groups teeth by remaining coronal tissue and ferrule; think of an anterior tooth that has lost more than half of its crown.
