Table 1. Intraclass correlation coefficients for the linear and angular variables used to assess intraexaminer reliability.

U1, Maxillary central incisor; U2, maxillary lateral incisor; U3, maxillary canine; U4, maxillary first premolar; U5, maxillary second premolar; U6, maxillary first molar; U7, maxillary second molar.

The landmarks were digitized twice and the variables were measured on two occasions 3 months apart by one examiner (DA). Intraclass correlation coefficients for the variables were computed to assess intraexaminer reliability. Intraexaminer reliability was obtained by a one-way random effects model. Intraclass correlation coefficients were significantly different from 0.
