Which ethnicity is most commonly associated with class 3 malocclusions?

African
Asian
White
Hispanic

The correct answer is: Asian

While it is true that malocclusions can occur in people of any ethnicity, research has shown that class 3 malocclusions are most commonly associated with individuals of Asian descent. This is because this particular type of malocclusion is often a result of genetics and craniofacial structure, which can vary among different ethnicities. Additionally, studies have found that individuals of Asian descent commonly have a larger lower jaw in relation to their upper jaw, which can contribute to a class 3 malocclusion. This does not mean that other ethnicities cannot have class 3 malocclusions, but it does indicate a higher likelihood in individuals of Asian descent. Therefore, B Asian is the most correct answer choice.
