What is the CEJ on a tooth?

The CEJ is the more or less horizontal demarcation line that distinguishes the crown (A) of the tooth from root (B) of the tooth. The cementoenamel junction, frequently abbreviated as the CEJ, is a slightly visible anatomical border identified on a tooth. It is the location where the enamel,...

What is cementoenamel junction (CEJ)?

Anatomical terminology. [edit on Wikidata] The cementoenamel junction, frequently abbreviated as the CEJ, is a slightly visible anatomical border identified on a tooth. It is the location where the enamel, which covers the anatomical crown of a tooth, and the cementum, which covers the anatomical root of a tooth, meet.

What is the relationship between enamel and cementum at the CEJ?

Cementoenamel junction. There exists a normal variation in the relationship of the cementum and the enamel at the cementoenamel junction. In about 60–65% of teeth, the cementum overlaps the enamel at the CEJ, while in about 30% of teeth, the cementum and enamel abut each other with no overlap.

What is the cementum of the tooth?

It is the location where the enamel, which covers the anatomical crown of a tooth, and the cementum, which covers the anatomical root of a tooth, meet. Informally it is known as the neck of the tooth.

What is gum recession and CEJ exposure?

This exposure is known as gum recession, the gums process of coming away from the tooths neck and shrinking down. To confirm this is the cause of your discomfort, a dental professional will measure the gum recession to determine the degree of CEJ exposure.

Cementum is the calcified covering that protects the root portion of the tooth and is not typically visible. The area where these two meet is also sometimes known as the cervical junction. Why is the cementoenamel junction significant?

What is the cementoenamel junction and cementum?

Cementum is the calcified covering that protects the root portion of the tooth and is not typically visible. The area where these two meet is also sometimes known as the cervical junction. The area around the cementoenamel junction is significant to a dentist because it is the area where the gums attach to the tooth.

What is the function of the cementum?

The cementum is thinnest at its junction with the enamel and thickest at the apex. The cementum gives attachment to the periodontal ligament fibers. Cementum forms throughout life, so as to keep the tooth in functional position. Cementum also forms as a repair tissue and in excessive amounts due to low grade irritants.
