Back

Marginal ridges are the raised borders of enamel that form the mesial and distal edges of the occlusal surfaces of posterior teeth and the incisal edges of anterior teeth.

Front

What is the significance of peg-shaped maxillary lateral incisors?

Back

Peg-shaped maxillary lateral incisors are a common dental anomaly where the tooth is smaller and shaped like a peg, often leading to aesthetic concerns and potential functional issues.

Front

How many teeth in the primary dentition have labial surfaces?

Back

There are 12 teeth in the primary dentition that have labial surfaces.

Front

What are elevations in dental anatomy?

Back

Elevations are raised areas on the tooth surface, such as cusps, ridges, and lobes, which contribute to the tooth's function and occlusion.

Front

What is a fossa in dental terms?

Back

A fossa is a shallow depression or concavity on the surface of a tooth, which is not considered an elevation.

Front

Front

What is the occlusal surface of a tooth?

Back

The occlusal surface is the top surface of posterior teeth that comes into contact with opposing teeth during chewing.

What are cusp ridges?

Back

Cusp ridges are the inclined planes that extend from the tips of the cusps of posterior teeth.
