Pulp Polyp
A pulp polyp, also known as chronic hyperplastic pulpitis, is a "productive" (i.e., growing) inflammation of Pulp (tooth), 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. Pathogenesis Pulp polyps develop as overgrowth of the pulpal tissue resulting in the hyperplastic mass. Factors which may contribute to the development of a pulp polyp includes: * Persistence of balance between the irritant and tissue resistance * Continuous low-grade inflammation * Well vascularised pulpal tissue with good tissue reactivity * An open carious cavity * Young patients with a good immune system * Wide apical foramen of the affected tooth to prevent the occurrence of pulpal strangulation and necrosis in response to inflammation Characteristics Pulp polyps are characterised by overgrowth of the pulp tissue outside the boundary of a tooth's pulp chamber. A pulp polyp may be found in an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulp (tooth)
The pulp is the connective tissue, nerves, blood vessels, and odontoblasts that comprise the innermost layer of a tooth. The pulp's activity and signalling processes regulate its behaviour. Anatomy The pulp is the neurovascular bundle central to each tooth, permanent or primary. It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth.Illustrated Dental Embryology, Histology, and Anatomy, Bath-Balogh and Fehrenbach, Elsevier, 2011, page 164. Because of the continuous deposition of the dentine, the pulp chamber becomes smaller with the age. This is not uniform throughout the coronal pulp but progresses faster on the floor than on the roof or sidewalls. Radicular pulp canals extend down from the cervical region of the crown to the root apex. They are not always straight but vary in shape, size, and number. They are ...
