Which term describes when both deciduous and permanent teeth are present?

• A. Mixed Dentition
• B. Adult Dentition
• C. Permanent Dentition
• D. Primary Dentition

Answer: (A)

When both deciduous and permanent teeth are present at the same time, the mouth is in mixed dentition. This is a developmental stage that typically occurs in children as primary teeth are still there while permanent teeth begin to erupt. The term “mixed dentition” specifically describes the coexistence of both dentitions, which is exactly what the question asks about. The other terms refer to a single dentition: adult or permanent dentition means only permanent teeth are present, while primary or deciduous dentition means only the original set of teeth is present.
