Ans. (B)

Ideal tooth width proportions when viewed from the front are one of many illustrations of the "Golden Proportion",

1.0: 0.62 : 0.38 : 0.24, etc. In this close-up view of attractive teeth on smile. it can be seen that the width of the lateral Incisor is 62% of the width of central incisor; the (apparent) width of canine is 62% of the width of lateral incisor; and the (apparent) width of first premolar is 62% of the canine.

Review At Glance- Width Relationship and the "Golden Proportion."- The apparent width of the maxillary anterior teeth on the smile. and their actuai mesio-distal width. differ because of the curvature of the dental arch. Particularly. only a portion of the canine crown can be seen in a frontal view. For best appearance. the apparent width of the laterai incisor (as one would perceive it from a direct frontal examination) should be 62% of that of the central incisor. the apparent width of the canine should be 62% of that of the lateral incisor. and the apparent width of first premolar

should be 62% of that of canine. This ratio of recurring 62% proportions appears in a number of other

relationships in human anatomy, and sometimes is referred to as the "Golden Proportion."
