Dental Assistant Practice Exam

What distinguishes the clinical crown from the anatomical crown?

1. Position relative to dental pulp

2. Amount of enamel present

3. Presence above or below the gum line

4. Type of tissues involved

The correct answer is: Presence above or below the gum line

The distinction between the clinical crown and the anatomical crown primarily relates to their position concerning the gum line. The clinical crown refers to the portion of the tooth that is visible above the gum line, which may vary in size due to factors such as periodontal disease or gum recession. In contrast, the anatomical crown encompasses the entire part of the tooth covered by enamel, regardless of its visibility above the gums. Since the clinical crown can change with oral health conditions that affect gum placement, this difference in visibility and positioning is crucial for dental professionals when assessing dental health and planning treatment. Understanding this distinction aids in better communication about dental conditions and interventions with patients.
