Generally posterior teeth are classified into:
- a- Anatomy (cusp) teeth.
- b- Non-anatomy (cuspless) teeth or flat.
- c- A and B.
- d- None.
The correct answer is c) A and B.
Posterior teeth can be classified into two main categories based on their anatomy:
- Anatomy teeth:
These teeth have distinct cusps and grooves on their occlusal surfaces. Examples include premolars and molars.
- Non-anatomy (cuspless) teeth or flat:
These teeth have smooth, flattened occlusal surfaces with minimal or no cusps. Examples include incisors and canines.
Therefore, both anatomy and non-anatomy teeth exist in the posterior region, depending on their specific location and function.
Other Options:
Here's a breakdown of the other options:
a) Anatomy (cusp) teeth:
While this statement accurately describes a specific type of posterior tooth, it excludes the non-anatomy teeth from the classification.
b) Non-anatomy (cuspless) teeth or flat:
This statement accurately describes another type of posterior tooth, but it excludes the anatomy teeth from the classification.
d) None:
This option is incorrect as both anatomy and non-anatomy teeth exist in the posterior region.
