Final answer:
A reservist needs to comply with an annual T-2 dental exam and be classified into Dental Class 1, meaning they are dentally fit and do not necessitate any treatment.
Step-by-step explanation:
A reservist must maintain readiness, which includes meeting health requirements such as the annual T-2 dental exam. Following this examination, a reservist must be classified into one of the four dental readiness classes. The appropriate class for a reservist who is in compliance with the annual exam and has no dental conditions would be Dental Class 1, indicating that the individual is currently dentally fit for duty and does not require any dental treatment or re-evaluation, besides the yearly exam.
