What are cervical enamel projections?

Cervical enamel projections are anatomical features observed on the tooth surface, particularly at the cervical area near the cementoenamel junction (CEJ). These projections occur when there is an abnormal extension of enamel from the CEJ into the furcation area of multirooted teeth, such as molars. This enamel extension can create an area that is more vulnerable to plaque accumulation and related periodontal issues.

The presence of cervical enamel projections can hinder proper periodontal cleaning and maintenance, making it challenging to achieve good oral hygiene in these areas. This anatomical variation can contribute to the development of periodontal diseases if not appropriately managed.

The other options do not accurately describe cervical enamel projections. Areas of exposed dentin refer to the loss of enamel or cementum, which is different from an enamel projection. Deep periodontal pockets are associated with the presence of periodontal disease and do not specifically describe a structural feature of teeth. Periapical pathosis pertains to diseases at the root apex, often related to pulp necrosis or infection, which is not connected to the morphology of the enamel at the CEJ.
