Which class of cavities does GV Black define as affecting 2 to 4 surfaces that include an interproximal?

• A. Class I
• B. Class II
• C. Class III
• D. Class V

Answer: (B)

GV Black classified cavities into different classes based on their location and the extent of the decay. Class II cavities specifically involve interproximal surfaces of posterior teeth, which means they affect two or more surfaces of a tooth, typically on the sides of molars and premolars. These cavities can impact not just the chewing surfaces but also the areas between the teeth where plaque can accumulate, making them more susceptible to decay. In this classification, the interproximal area is crucial, as it highlights the need for careful cleaning and monitoring, which is vital for dental health. This understanding is fundamental for dental assistants in identifying, preventing, and appropriately caring for patients with such cavities.
