This document describes a diagnostic and prognostic tool to identify disturbances in the eruption of the upper canine tooth at an early developmental stage using 3 sentences or less: The tool uses measurements of the distances between craniofacial landmarks taken from radiographs to calculate a score, where a score less than -0.565 indicates a 95.3% chance the canine will be impacted during eruption. Two examples are provided to illustrate use of the tool.
