Cast - Radiograph Evaluation

ALIGNMENT/ROTATIONS

0.5 – 1 mm = 1 for each tooth
> 1 mm =  2 for each tooth

OCCLUSAL CONTACTS

0 mm = satisfactory
≤ 1 mm = 1 (for each posterior tooth
> 1 mm = 2    out of contact)

** Do not score diminutive distolingual cusps of the maxillary 1st and 2nd molars, nor lingual cusps of the mandibular first premolars. Maximum of 2 points per tooth.

MARGINAL RIDGES

0.5 - 1 mm = 1 (for each interproximal contact between posterior teeth)
> 1 mm = 2

**Do not include the canine-premolar contact.
**Do not include the distal of lower 1st premolar.

OCCLUSAL RELATIONSHIP

< 1 mm = satisfactory
1 - 2 mm = 1 (for each maxillary tooth from
> 2 mm = 2    the canines to the 2nd molars)

BUCCOLINGUAL INCLINATION

0 - 1 mm = satisfactory
1.1 - 2 mm = 1 ( for each posterior tooth)
> 2 mm = 2

**Do not score the mandibular 1st premolars nor the distal cusps of the second molars.

INTERPROXIMAL CONTACTS

0.6 - 1 mm = 1 (for each interproximal contact)
> 1 mm = 2

OVERJET

Anterior teeth must be contacting.
0 mm = satisfactory
≤ 1 mm = 1 (for each maxillary tooth)
> 1 mm = 2

Transverse posterior teeth:
Mandibular buccal cusps are measured to the central fossa of the maxillary teeth.

ROOT ANGULATION

Parallel = 0
Not parallel = 1
Root contacting  
adjacent root = 2 (for each occurrence)

**Do not score the maxillary and mandibular canines.  

NOTE:  Gauge Width is 0.5 mm; Gauge Height is 1 mm
Third molars are not scored unless they substitute for the second molars.
No tooth is scored more than two points per individual parameter.
