The constricted area where the anatomic crown meets the root of the tooth is known as?

Neck
Cervix
Alveolar Process
Clinical Crown

The correct answer is: Cervix

The correct term for the constricted area where the anatomic crown meets the root of the tooth is the cervix. This area is also known as the cemento-enamel junction (CEJ), where the enamel of the crown meets the cementum covering the root. Understanding this structure is crucial in dental anatomy and practice, as it plays a vital role in the overall health of the tooth and its supporting structures. To provide more context, the neck of the tooth is a term often used synonymously with the cervix, but from a more anatomical perspective, cervix is the more precise term typically used in dental literature. The alveolar process refers to the bony structure that contains the sockets of the teeth, while the clinical crown is the portion of the tooth that is visible above the gum line, which may not necessarily correspond with the anatomic crown in cases of gum recession. Recognizing these distinctions is important for understanding tooth anatomy and its implications in dental care.
