Summary – What are Crack Removal Endpoints (CrRE)?

Crack Removal Endpoints (CrRE) are used to measure the areas in which complete removal of cracks is indicated, and the areas in which partial removal of cracks should be carried out. The primary aim is to remove cracks in the tooth while avoiding pulp exposure.

Crack Removal Endpoints are measured using a periodontal probe angled along the long axis of the tooth:
Horizontally – 3 mm interproximally from the adjacent tooth’s marginal ridge.
Vertically – 5 mm occlusally from the cavo-margin.
