HOSA Dental Terminology Practice

What is the term ‘occlusal’ associated with?

1. Surface of incisors

2. Surface of molars and premolars

3. Inner surface of posterior teeth

4. Outer layer of gums

The correct answer is: Surface of molars and premolars

The term ‘occlusal’ refers to a specific area of the teeth that is crucial in dental terminology. It is primarily associated with the biting surfaces of the molars and premolars. These teeth play a significant role in the chewing process, and the occlusal surface is where the upper and lower teeth come into contact when biting down. This surface is flat or slightly convex to facilitate the grinding and crushing of food. Understanding 'occlusal' is vital for dental professionals when discussing tooth wear, malocclusions, and the fitting of dental restorations. The other answers pertain to different aspects of dental anatomy. The surface of incisors relates to a different category of teeth primarily designed for cutting. The inner surface of posterior teeth refers to aspects involving the inside surfaces that face the tongue or cheeks, while the outer layer of gums pertains to the soft tissue surrounding the teeth. Thus, the association of ‘occlusal’ specifically with the surfaces of molars and premolars highlights its importance in dentistry, especially regarding masticatory function.
