HOSA Dental Terminology Practice

What are rugae in dental terms?

1. Large ridges on the molars

2. Small ridges of tissue extending across the hard palate

3. Ridges found on the gum line

4. Structures that connect teeth to the jaw

The correct answer is: Small ridges of tissue extending across the hard palate

Rugae refer to small ridges of tissue that extend across the hard palate, which is the bony front portion of the roof of the mouth. These folds of tissue serve several functions, including aiding in the mechanical process of food manipulation during chewing and contributing to the overall oral architecture, which helps in certain aspects of speech. The presence of rugae also plays a role in the growth and development of the palatal tissues and can provide landmarks for dental professionals during examinations and procedures. Recognizing the anatomy of the hard palate, including rugae, is essential for understanding overall oral health and function.
