Does selective root canal retreatment preserve the tooth's fracture resistance? An ex-vivo study.

ABSTRACT:

Objectives

To assess the tooth's fracture resistance when submitted to a selective root canal retreatment compared to the conventional approach.

Methods

33 intact permanent mandibular first molars were selected according to specific criteria. After teeth mounting, the primary root canal treatment was conducted and followed by thermo-mechanical aging procedures to mimic a few clinical conditions. The specimens were randomly divided into three groups (n = 11); a control group in which intact teeth were used and two experimental groups according to the retreatment approach: conventional non-surgical retreatment (Conventional-NSR), and selective non-surgical retreatment (Selective-NSR). Later, the teeth were submitted to a final thermo-mechanical aging procedure and tested regar
