Which term describes the selected teeth that are visible through the dental dam?

The correct term to describe the selected teeth that are visible through the dental dam is "exposed." When using a dental dam in dental procedures, only the specific teeth that are intended for treatment are meant to be visible. This visibility allows the dentist to work effectively while maintaining a dry field, free from contamination. The exposure of these teeth is an essential part of the procedure, ensuring that the treatment area is optimal for both the dentist and patient.

In contrast, the other terms do not accurately describe the situation with the dental dam. "Isolated" refers to the separation of a tooth or area from the rest of the oral cavity, but the focus here is more on visibility. "Malaligned" indicates that teeth are not properly aligned, which is unrelated to their visibility through the dam. "Inverted" typically means something turned inside out, which does not apply to the context of teeth being visible through a dental dam. Thus, "exposed" is the most appropriate choice in this scenario.
