TEST BANK FOR ANATOMY OF OROFACIAL STRUCTURES 8TH EDITION BRAND

Chapter 02: The Tooth: Functions and Terms Brand/Isselhard: Anatomy of Orofacial Structures, 8th Edition MULTIPLE 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. REF: pp. 15-17 OBJ: To identify the different tissues that compose teeth NAT: CDA: GC I.A.7. Identify basic oral and dental anatomy, physiology, and development, including but not limited to: teeth. TOP: BLOOM: Remembering 2. Each of the following terms refers to an “in-between” surface EXCEPT one. Which one is the EXCEPTION? a. Facial b. Mesial c. Distal d. 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. REF: p. 19 OBJ: To define the terminology used in naming the landmarks of teeth NAT: CDA: GC I.A.7. Identify basic oral and dental anatomy, physiology, and development, including but not limited to: teeth. | CDA: GC I.C.2. Identify the surfaces of the tooth. TOP: BLOOM: Remembering 3. Which of the following is an example of a line angle? a. Mesiolabioincisal b. Buccolingual c. Mesiodistal d. Labioincisal e. Inciso-occlusal ANS: D
