HOSA Dental Terminology Practice

What condition is indicated by the term craniosynostosis?

1. Abnormal growth of teeth

2. Premature closure of cranial sutures

3. Excessive jaw development

4. Jaw misalignment

The correct answer is: Premature closure of cranial sutures

Craniosynostosis refers specifically to the condition where there is a premature closure of one or more cranial sutures, which are the fibrous joints between the bones of the skull. This early fusion restricts the normal growth of the skull, leading to an abnormal head shape and potentially causing increased intracranial pressure and developmental delays. The proper alignment and development of the skull are crucial during the growth phases of a child, and craniosynostosis can significantly impact this process. The other options relate to dental and jaw conditions but do not accurately describe craniosynostosis. Abnormal growth of teeth, excessive jaw development, and jaw misalignment pertain to different dental issues and do not involve the cranial sutures at all. Therefore, the selection highlighting the premature closure of cranial sutures accurately captures the essential aspect of craniosynostosis.
