HOSA Dental Terminology Practice

What does the term contact point refer to?

1. A major pointed or rounded eminence on a tooth

2. Specific point at which a tooth from one arch occludes with another tooth from the opposing arch

3. A space in the dentin occupied by the odontoblastic process

4. All teeth in the maxillary or mandibular jaw that form an arch

The correct answer is: Specific point at which a tooth from one arch occludes with another tooth from the opposing arch

The term "contact point" specifically refers to the exact location where a tooth from one arch makes contact with a tooth from the opposing arch during occlusion. This is vital in dental anatomy and function as it plays an essential role in how teeth align and interact when a person bites down or chews. Proper contact points are critical for efficient biting and chewing, as well as for maintaining the overall alignment of teeth and the health of the occlusal surfaces. Understanding contact points aids in diagnosing bite issues or occlusal discrepancies, which can lead to various dental problems if not addressed. The involvement of contact points directly relates to how stability and functionality are achieved in the dental arch. Other options, while related to dental terminology, do not accurately describe the specific meaning of contact points in this context.
