Figure 1: Points. and measurements in methods of evaluating symmetry in children. IN: incisor; C: canine; M: molar. (a): from the incisal point to the canine cusp tip; (b): linear distance from the canine cusp tip to the distobuccal cusp tip of the first deciduous molar; (c): linear distance from the incisal point to the distobuccal cusp tip of the first deciduous molar (Method 1). I: incisor; C: right canine; C’: left canine; M: right molar; M’: left molar. (a): from the cusp tip of the right canine to the distobuccal cusp tip of the first deciduous right molar; (b): from the distobuccal cusp tip of the right deciduous first molar to the left canine cusp tip; (c): from the cusp tip of the right canine to the distobuccal cusp tip of the left deciduous first molar; (d): from the cusp tip of the left canine to the distobuccal cusp tip of the left deciduous first molar (Method 2).
