If a root canal were needed on tooth 4, what is the most likely configuration of the canals?

One canal in one root
Two canals in one root
One canal in two roots
Two canals in two roots

The correct answer is: One canal in one root

Explanation For tooth 4, it is most likely that there will only be one canal in one root. This is because tooth 4 typically only has one root, so it makes sense that there would only be one canal associated with it. Option B is incorrect as it suggests there would be two canals in one root, which is not a common configuration for this tooth. Option C is incorrect as it suggests there would be one canal in two roots, which is not possible for this tooth since it typically only has one root. Option D is also incorrect as it suggests there would be two canals in two roots, which, again, is not a common configuration for this tooth. Therefore, option A is the most likely and correct configuration for a root canal on tooth 4.
