Endodontic retreatment decision-making: The influence of the framing effect.

Objective: The aim of this study was to explore the influence of a framing effect in retreatment decision-making of a root-filled tooth with asymptomatic apical periodontitis (AP).

Method: Two variants of a questionnaire were created in which the factual information about a root filled with AP was identical. The options in the first variant were framed in favor to wait and see (FW) and those in the other variant were framed in favor of retreatment (FR) Two hundred and forty-eight volunteers were by chance given one of the two versions and were asked to choose between having retreatment or to wait and see.
