What characterizes a simple cavity?

1. Decay on multiple surfaces

2. Decay affecting the root only

3. Decay on only one surface

4. No visible decay

The correct answer is: Decay on only one surface

A simple cavity is characterized by decay that affects only one surface of a tooth. This type of cavity is typically classified as a minimal decay that can easily be treated through restorative procedures such as fillings. When decay is limited to a single surface, it allows for a more straightforward treatment process and has a better prognosis due to the lesser extent of tooth structure lost. In contrast, cavities that affect multiple surfaces or the root involve more complex interventions and may require more extensive restorative work. Additionally, cavities with no visible decay do not qualify as cavities because they show no signs of decay at all.
