If the distolingual cusp is short or diminutive (fig. 15), it should not be considered in the evaluation. If this cusp is prominent, but does not contact with the opposing arch, then points may be scored. If the cusps are in contact with the opposing arch, no points are scored. Do not score diminutive distolingual cusps of the maxillary 1st and 2nd molars, nor lingual cusps of the maxillary first premolars.

figure 15

If a cusp is out of contact with the opposing arch, and the distance is 1 mm or less (fig. 16), then 1 point is scored for that tooth. If the cusp is out of contact and the distance is greater than 1 mm (fig. 17), then 2 points are scored for that tooth. No more than 2 points are scored for each tooth.
