Dental Assistant Practice Exam

Which two classes of teeth are considered non-deployable?

1. Class 1 and Class 2

2. Class 3 and Class 4

3. Class 5 and Class 6

4. Class 7 and Class 8

The correct answer is: Class 3 and Class 4

In dentistry, the classification of teeth often refers to their developmental issues, structure, or potential for deployment in various dental procedures, especially when considering whether certain teeth are likely to be conserved or require extraction due to severe pathology. Class 3 and Class 4 teeth are considered non-deployable primarily because they exhibit significant structural compromise or pathology that makes them unsuitable for restorative procedures. Class 3 teeth may indicate moderate to severe caries or damage affecting the tooth's structure, while Class 4 generally relates to teeth that are significantly damaged or non-restorable. Their condition typically precludes any practical efforts to repair or maintain them, leading to extraction being the preferred option. Understanding the distinctions between these classes and their implications for dental treatment is essential for making informed decisions regarding a patient's dental care and treatment plans.
