HOSA Dental Terminology Practice

Which dental condition is characterized by excess filling material?

1. Underfilling

2. Overhanging restoration

3. Crown lengthening

4. Tooth erosion

The correct answer is: Overhanging restoration

The dental condition characterized by excess filling material is overhanging restoration. This typically occurs when a dental filling extends beyond the edges of the tooth, leading to an uneven surface or a portion of the filling that protrudes outside of the normal contour of the tooth. Such overhangs can create issues, including difficulty in cleaning the area properly, potential plaque accumulation, and increased risk for decay or periodontal problems adjacent to the restoration. Understanding this condition is important for dental professionals to ensure proper restoration techniques are employed, thereby optimizing both the functionality and aesthetics of dental work while promoting overall oral health. In contrast, underfilling refers to a situation where a restoration does not adequately fill the prepared tooth structure, crown lengthening involves surgical procedures to adjust gum levels or bone to allow for a proper crown placement, and tooth erosion pertains to the loss of dental hard tissue due to acid exposure, none of which involve excess filling material.
