HOSA Dental Terminology Practice

What is the cervix in dental terminology?

1. Broad area of the tooth

2. Constricted structure at the crown and root junction

3. Part of the gum tissue

4. Bone surrounding the tooth

The correct answer is: Constricted structure at the crown and root junction

The cervix in dental terminology refers to the constricted area located at the junction between the crown and the root of a tooth. This region is significant because it serves as the transition point where the visible part of the tooth (the crown) meets the part embedded within the gumline (the root). Understanding the cervix is important in dental hygiene and practices, as this area can be vulnerable to various dental issues, such as gum disease and tooth decay. The other answer choices refer to different aspects of dental anatomy: the broad area of the tooth is more representative of the crown itself; part of the gum tissue refers to the soft tissue surrounding the teeth; and the bone surrounding the tooth indicates the alveolar bone, which supports the tooth structure. Each of these components contributes to oral health but does not define the cervix.
