Study Notes

Younger patients tend to prefer lighter tooth colors, while older patients' teeth naturally darken due to deposition of secondary dentin, wearing away of enamel, and external staining.
Females generally prefer brighter teeth than males.
The color of teeth should harmonize with the color of the face, with lighter teeth suitable for lighter skin and darker teeth for darker skin.
The size of teeth should be in proportion to the size of the face and head. Women's teeth are often smaller than men's, and the incisal level of central and lateral teeth is desirable to be distinct in women.
To determine the size of teeth, methods using pre-extraction guides, anthropological measurements, and theoretical concepts can be used.
Pre-extraction guides include diagnostic casts, photographs, and radiographs. Anthropological measurement methods include the Sears cephalic index, Berry's biometric index, and H. Pound's formula. Theoretical concepts include Winkler's three-perspective approach, typal form theory, and the concept of harmony.
The size and color of teeth should be in harmony with the size of the head and color of the sclera.
Seven anatomic entities are used as guides to selection of anterior teeth for size: the size of the face, incisal papilla and the cuspid eminence or the Buccal Frenum, maxillomandibular relations, the contour of the residual ridges, the vertical distance between the ridges, and the lips.
Tooth selection is also based on the shape of the patient's face or facial form and profile. The labial surface of the upper central incisor should be in harmony with the profile of the face.
