Fusion is a condition resulting from what?

The merging of two tooth buds into a single tooth
The complete absence of one tooth
The formation of an extra tooth
The abnormal displacement of a tooth

The correct answer is: The merging of two tooth buds into a single tooth

Fusion is a dental anomaly that occurs when two tooth buds fuse together during development, resulting in the formation of a single large tooth. This is why option A, "The merging of two tooth buds into a single tooth," is the correct answer. Options B, C, and D are not correct in this context. The complete absence of one tooth (option B) refers to the condition of hypodontia or oligodontia, where there is a missing tooth or multiple missing teeth. The formation of an extra tooth (option C) is known as supernumerary teeth, which is a condition where there are more teeth than the normal dental formula. The abnormal displacement of a tooth (option D) describes ectopic eruption or transposition, where a tooth erupts in an abnormal position or switches places with another tooth.
