Resistance to fracture of endodontically treated teeth: Influence of the post systems and cements.

Background: Endodontically treated teeth with extensive structural damage present higher fragility due to the low amount and worse quality of the reminiscent tissues of the crown.

Materials And Methods: The present study evaluated the effect of different intraradicular retainers and cementation agents on the fracture resistance of devitalized teeth. Incisive teeth ( = 40) of bovine mandibles were used.
