The Goslon Yardstick: a new system of assessing dental arch relationships in children with unilateral clefts of the lip and palate

Abstract

The Goslon (Great Ormond Street, London and Oslo) Yardstick is a clinical tool that allows categorization of the dental relationships in the late mixed and or early permanent dentition stage into five discrete categories. Cases are allocated to these categories on a value judgment basis by reference to the anchor groups of the Goslon Yardstick. The categorization was sufficiently sensitive to distinguish the treatment results at different centers in this study. It is proposed that the Goslon Yardstick should facilitate cross-center studies.
