Dental Assistant Practice Exam

The occlusal surfaces specifically refer to the broad chewing surfaces of the posterior teeth, which include the molars and premolars. These surfaces are designed for grinding and crushing food during the chewing process. The unique structure of the occlusal surfaces, with their cusps and fissures, allows for effective mastication.

In contrast, the anterior teeth, such as incisors and canines, do not have occlusal surfaces; instead, they feature narrow cutting edges that are adapted for slicing food. Therefore, the functions and designs of the occlusal surfaces are specific to the posterior teeth, highlighting the importance of understanding dental anatomy and the roles different sections of teeth play in oral health and function.
