In the anterior region, if the mandibular canines or incisors are not contacting lingual surfaces of the maxillary canines and incisors, and the distance is 1 mm or less (fig. 28), then 1 point is scored for each maxillary tooth. If the discrepancy is greater than 1 mm (fig. 29), then 2 points are scored for each maxillary tooth.

This assessment is made by viewing the maxillary and mandibular dental casts from an occlusal perspective. The mesial and distal surfaces of the teeth should be in contact with one another (fig. 30). If 0.50 mm or less interproximal space exist, then no points are scored.
