In acute caries:

The caries progresses slowly

The caries tends to involve the pulp much later

It is most common in adults

Leads a rapid clinical course resulting in early pulp involvement

In acute caries:

Usually there is no or less pain

The pulp protects itself by sclerosis

Slow progression of caries process

It mostly involves young age group

It leads a rapid clinical course towards the pulp

It mostly involves young age group

Pain is a more common feature of chronic caries than acute caries

It is most common in adults
