A pulp polyp, also called as Chronic hyperplastic pulpitis, is found in an open carious lesion, fractured tooth or when a dental restoration is missing. Due to lack of intrapulpal pressure in an open lesion pulp necrosis does not take place as would have occurred in a closed caries case. Also a good vascular and immune supply is necessary. It is a productive pulpal inflammation where the development of granulation tissue is seen.
