E = Enamel; D = Dentine; Front B = Buccal surfaces of canines and incisors in both upper and lower jaw; Front P = Palatal surfaces of canines and incisors in upper jaw; Lateral segments B = Buccal surfaces of premolars and molars in both upper and lower jaw; Lateral segments P = Palatal surfaces of premolars and molars in upper jaw; Lateral segments O = Occlusal surfaces of premolars and molars in both upper and lower jaw.
