HOSA Dental Terminology Practice

Which dental term describes a relationship where teeth do not align correctly in the arch?

1. Occlusion

2. Alignment

3. Crowding

4. Spacing

The correct answer is: Crowding

The correct term for a relationship where teeth do not align correctly in the arch is occlusion. Occlusion refers to the way teeth meet and how the upper and lower teeth contact each other when biting or chewing. Proper occlusion allows for efficient biting and chewing, while misalignment can lead to various dental issues, including uneven wear on teeth, jaw pain, and difficulties in speaking or chewing. Crowding specifically refers to a situation where there is not enough space in the dental arch for all the teeth to fit properly, leading to overlapping or twisted teeth. While crowding is a significant factor in alignment issues, it is a specific condition resulting from misalignment, rather than the term that broadly describes the relationship of all teeth in the arch concerning their alignment. Alignment generally describes the positioning of teeth, but it does not capture the functional and contact relationship that occurs during occlusion. Spacing denotes the gaps or spaces between teeth, which can also contribute to alignment issues but is not the overarching term for the relationship of teeth within the arch. Thus, occlusion is the most accurate term for describing the overall alignment relationship of teeth.
