HOSA Dental Terminology Practice

What is a capsule in dental terminology?

1. Outer layer of the tooth enamel

2. Fibrous band of tissue surrounding a joint

3. Connective tissue supporting the gums

4. Layer of dentin beneath the enamel

The correct answer is: Fibrous band of tissue surrounding a joint

In dental terminology, a capsule refers to a fibrous band of tissue that surrounds certain types of organs or structures, providing stability and protection. This is particularly relevant in the context of the periodontium, where the capsule plays a role in housing the tooth and supporting structures, helping to maintain their integrity within the oral cavity. The other choices present terms that relate to different aspects of dental anatomy or physiology but do not align with the definition of a capsule. The outer layer of the tooth enamel pertains specifically to the hard, protective covering of a tooth. The connective tissue supporting the gums refers to the periodontal ligament and supporting tissues, which serve different functions than a capsule. The layer of dentin beneath the enamel is an essential component of tooth structure, but again, it does not relate to the concept of a capsule. Understanding these distinctions is crucial in grasping the complex terminology used in dentistry.
