Tooth fusion occurs with greater frequency in_______________?
Show answer Hide answer
Answer: A. Primary dentition
Explanation
Tooth fusion happens with significantly greater frequency in the primary dentition than in permanent teeth. The close proximity of developing primary tooth buds facilitates their physical union during early odontogenesis. Developmental dynamics during early childhood make primary incisors particularly susceptible to this union phenomenon. Tooth fusion is a developmental anomaly resulting from the union of two adjacent separate tooth germs. The process creates a single large clinical tooth structure with a confluent dentin and enamel bridge. Counting the total number of teeth in the arch typically reveals one fewer tooth than normal.
Permanent dentition displays a much lower prevalence of true anatomical tooth fusion compared to primary teeth. Mixed dentition represents a transitional developmental stage rather than a specific category with heightened fusion rates. The option stating none of the above is incorrect because primary dentition clearly shows the highest frequency.
