What does "fusion" refer to in dental terminology?

1. Coalescence of two dental roots

2. Two teeth that fuse at their dentin while developing

3. The bonding of enamel and dentin

4. A treatment for dental cavities

The correct answer is: Two teeth that fuse at their dentin while developing

In dental terminology, "fusion" specifically refers to the process where two teeth become physically joined together during their development. This typically occurs at the dentin level, where the two teeth's tissues merge, leading to a single tooth structure rather than distinct, separate teeth. This condition can be observed in the primary or permanent dentition and may result in a tooth that appears larger or has an atypical shape. Understanding this concept is crucial for dental professionals, as fused teeth can impact the alignment, occlusion, and overall dental health of a patient. While other options involve aspects of dental anatomy and treatment, only the definition related to the merging of developing teeth accurately captures the meaning of "fusion."
