Table 7. Inter-examiner reliability of measurements made on intraoral photographs of the dental arches (examiners A and B).

ICC: intraclass correlation coefficient; SD: standard deviation; TSALD: tooth size-arch length discrepancy; LII: Little's Irregularity Index; BBL: basal bone length; STS: sum of teeth sizes.
