HOSA Dental Terminology Practice

Which term refers to the outmost edge of the gingiva?

1. Dehisence

2. Gingival margin

3. Cortical area

4. Occlusal surface

The correct answer is: Gingival margin

The gingival margin refers specifically to the outer edge or border of the gingiva, which is the soft tissue surrounding the teeth. This term is fundamental in dental terminology, as it helps in understanding the anatomical positioning of the gums in relation to the teeth. Maintaining a healthy gingival margin is crucial in periodontal health, as it is the point where the gingiva meets the enamel of the teeth. Dehiscence refers to a medical condition characterized by the separation or rupture of a tissue, particularly in surgical contexts, not specifically related to the gingiva’s anatomical edges. The cortical area pertains to the outer layer of bone surrounding the dental structures and is not synonymous with the gingival margin. The occlusal surface is the top surface of the teeth responsible for chewing and biting, which does not relate to the edges of the gingiva. Therefore, the gingival margin is the appropriate term indicating the outermost edge of the gingiva.
