A pulp polyp, also known as chronic hyperplastic pulpitis, is a "productive" (i.e., growing) inflammation of dental pulp in which the development of granulation tissue is seen in response to persistent, low-grade mechanical irritation and bacterial invasion of the pulp.

What causes chronic hyperplastic pulpitis?

Hyperplastic pulpitis is a type of irreversible chronic pulpitis that occurs usually in young teeth where the pulp has been exposed by caries or trauma (1).

How is chronic hyperplastic pulpitis treated?

Hyperplastic pulpitis is a variety of chronic open pulpitis which is regarded as irreversible. This condition is usually treated by root canal treatment, unless coronal damage does not permit restoration, in which case extraction is indicated.
