ANATOMY OF OROFACIAL STRUCTURES 8TH EDITION BY BRAND TEST BANKMULTIPLE CHOICE 1. The sensation of pain is felt in which part of the tooth? a. Enamel b. Dentin c. Cementum d. Pulp ANS: D The dental pulp is the sensory and nourishing portion of the tooth. It is composed of blood vessels, lymph vessels, connective tissue, and nerve cells. The pulp also contains special dentin-reparative/formative cells called odontoblasts. Sensation of pain is not felt in enamel, cementum, or dentin.

Proximal ANS: A Proximal, mesial, and distal are terms that describe surfaces of teeth that face a neighboring tooth; they also can be thought of as “in-between” surfaces. Proximal is the more general term for this type of surface. More specifically, a mesial surface is the proximal surface of a tooth closest to the midline; distal describes the proximal surface farthest from the midline. Facial surfaces are NOT proximal surfaces. Facial surfaces are more specifically known as labial (lip) surfaces on anterior teeth or buccal surfaces on posterior teeth.
