Table 3: Correlation between crown measurements of lateral incisors and canines, root lengths of lateral incisors, transverse maxillary widths, and the linear and angular measurements of canine position. Regarding root dimensions, root length of the lateral incisor showed a strong positive correlation with transverse width at the premolar level (r = 0.487, \(p\) = 0.001). The occluso-gingival crown length of the lateral incisor also presented a significant negative correlation with canine angulation relative to the palatal suture (r = \(-\)0.446, \(p\) = 0.002).
