Which dentition is most likely to exhibit prematurely erupting primary teeth?

• A. Deciduous dentition
• B. Permanent dentition
• C. Mixed dentition
• D. None of the above

Answer: (A)

The deciduous dentition, also known as primary or baby teeth, is the stage in which prematurely erupting primary teeth can be most commonly observed. During this period, the primary teeth are expected to erupt in a specific sequence and at particular ages, but variations can occur. Premature eruption refers to teeth coming in earlier than the typical schedule, which can particularly happen with primary teeth due to various factors such as genetic predisposition, environmental influences, or localized dental issues.

In contrast, the permanent dentition phase primarily involves the eruption of adult teeth and does not typically experience what is classified as premature eruption in the same context. The mixed dentition stage, which occurs when both primary and permanent teeth are present, may also show potential anomalies in eruption, but the phenomenon of prematurely erupting teeth is more associated with the primary teeth themselves. Therefore, the deciduous dentition is the correct choice, as it is during this time that the challenge of premature eruption is most pertinent.
