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

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

Answer: (A)

During dental development, there is a period when both deciduous (baby) teeth and erupting permanent teeth are present in the mouth. This stage is known as mixed dentition. It typically occurs roughly from ages 6 to 12, as primary teeth are shed and permanent teeth come in. This phase is important for treatment planning, such as managing space for erupting teeth and guiding proper bite development. The other terms describe different situations: primary dentition means only the baby teeth are present; permanent dentition means only the adult teeth are present after the transition is complete; edentulous means there are no teeth at all. Therefore, the term that describes having both deciduous and permanent teeth present is mixed dentition.
