In dental diagnostic classification, how is a tooth with normal vitality but exhibiting caries classified?

A tooth that has normal vitality but shows the presence of caries is classified as having "Reversible pulpitis." In this case, the tooth’s pulp is still healthy and capable of healing, but the presence of caries indicates that there is a threat to the pulp’s health.

Reversible pulpitis essentially means that the pulp is inflamed due to irritation, which is often reversible if the irritant (like caries) is removed before it progresses further. Since the tooth maintains normal vitality, it suggests that the pulp is not severely affected and can recover once treated.

In contrast, irreversible pulpitis or necrotic pulp would suggest that the condition of the pulp is either beyond repair or has already died, which does not apply in this situation. Therefore, classifying the tooth with normal vitality and caries as "Reversible pulpitis" accurately reflects the current state of the pulp and the potential for recovery following appropriate dental treatment.
