Due to lack of intrapulpal pressure in an open lesion, pulp necrosis does not occur as would be expected in a closed carious cavity.
A good vascular supply and immune resistance is required for its development; as such, this condition is more commonly seen in molar teeth of children and young adults and rarely in older age groups.
Pulp polyps usually show no radiographic apical lesions, however in long standing polyps or in those with extensive pulp involvement, chronic apical periodontitis may develop and present as a radiographic peri-apical lesion due to advancement of the inflammation present.
This may involve a combination of treatments including root surface debridement, endodontic therapy, crown lengthening and/or fixed prosthodontics measures.
[1] The types of endodontic therapy which may be undertaken are either a pulpotomy or a root canal treatment;[6] other than restorability, the option chosen depends on a number of factors including how far the tooth is from root completion, the extent of pulpal involvement and whether it is a primary or permanent tooth.
