HOSA Dental Terminology Practice

Which of the following relates to the concept of 'crevice' in dentistry?

1. A tool for dental cleaning

2. A space for dental cavities

3. A narrow opening caused by a crack

4. A technique for pain management

The correct answer is: A narrow opening caused by a crack

The concept of 'crevice' in dentistry refers specifically to a narrow opening, often the result of a crack or a separation between surfaces. Crevices can occur in various contexts within the oral cavity, such as in the spaces between teeth or along the margins of restorations. These narrow spaces can trap plaque and bacteria, making them relevant to oral hygiene and the formation of caries if not adequately cleaned. Understanding that a crevice is a physical space helps dental professionals assess potential areas of risk for decay or periodontal issues. In contrast, a tool for dental cleaning might help remove debris but doesn't define the space itself. A space for dental cavities generally refers to areas prone to decay rather than the specific concept of a crevice. A technique for pain management does not relate to the physical characteristics implied by the term crevice. Thus, the definition that aligns most closely with the concept is indeed that of a narrow opening caused by a crack.
