Question

Dentofacial proportions and the anatomic basis of malocclusion are most effectively evaluated on ____________ radiographs.

1) cephalometric
2) panoramic
3) periapical
4) occlusal

Answer 1

Dentofacial evaluation is best conducted using cephalometric radiographs. Deciduous teeth emerge early in childhood, permanent teeth during late childhood to adolescence, and wisdom teeth in late adolescence to early adulthood.

Step-by-step explanation:

Dentofacial proportions and the anatomic basis of malocclusion are most effectively evaluated on cephalometric radiographs. Cephalometric radiographs allow for the assessment of skeletal relationships within the head, which is critical for diagnosing and planning treatment for malocclusions and other dental and facial irregularities.

CHAPTER SUMMARY REVIEW

At which stages in the human lifespan do deciduous teeth, permanent teeth, and wisdom teeth generally emerge?

• Deciduous teeth typically emerge between 6 months and 2 years of age.
• Permanent teeth usually begin to replace deciduous teeth around age 6 and continue to emerge until adolescence.
• Wisdom teeth, the final set of molars, most commonly emerge in late adolescence or early adulthood, typically between 17 and 25 years old.
