Dental Arch Measurements (DAM)	Mean (mm)	Beta-coefficient observed vs predicted (p-value)	Correlation Coefficient DAM vs. SIu (p-value)	Beta-coefficient** DAM vs. SIu (p-value)
AAW (observed) AAW* (Pont’s)	35.54 37.71	0.355 (<0.001)	0.296 (<0.01) 1.0 (<.01)	0.42 (<0.01) 1.2 (<0.01)
PAW (observed) PAW** (Pont’s)	48.1 49.3	0.215 (<0.05)	0.255 (<0.02) 1.0 (<0.01)	0.33 (>0.05) 1.5 (<0.01)
Lu (observed) Lu*** (Pont’s)	17.8 20.03	0.779 (<0.001)	0.478 (<0.001) 1.0 (<0.01)	0.46 (<0.01) 6.3 (<0.01)

Independent t test showed that predicted dental arch measurements were significantly greater than the observed measurements at p <0.01
