HOSA Dental Terminology Practice

What does "frenum" refer to in dental terminology?

1. A type of dental procedure

2. Muscle fibers attaching oral structures to mucosa

3. A dental hygiene tool

4. A specific tooth anatomy

The correct answer is: Muscle fibers attaching oral structures to mucosa

In dental terminology, "frenum" refers to muscle fibers that attach oral structures, such as the lips and tongue, to the underlying mucosa of the mouth. These fibrous bands are crucial in maintaining the position and function of oral tissues. For instance, the frenulum of the tongue helps stabilize it and maintains proper movement, which is essential for activities such as speaking and swallowing. Understanding the role of the frenum is important in dental practice, especially in procedures related to oral surgery or orthodontics, where the frenum can impact tooth positioning and alignment.
