Which term describes the front surface of the anterior teeth?

• A. Labial/Facial
• B. Incisal
• C. Buccal
• D. Occlusal

Answer: (A)

The front surface of the anterior teeth is described as the labial surface because it faces the lips. Labial is the term used for surfaces toward the lips, and for anterior teeth that same surface is often referred to as facial as well since it faces the face. Incisal refers to the cutting edge of the anterior teeth, not the surface facing the lips. Buccal describes the surface toward the cheek (more relevant to the outer sides of posterior teeth), and occlusal is the chewing surface on the back teeth. So, Labial/Facial correctly identifies the front surface of the anterior teeth.
