A recently traumatized tooth can present with what response to EPT?

False positive
True positive
False negative
No response

The correct answer is: False negative

When a tooth has been recently traumatized, it can lead to injury of the nerve fibers within the tooth. This injury can result in decreased sensitivity of the tooth to stimuli such as the Electric Pulp Tester (EPT). Therefore, a recently traumatized tooth may not respond as expected to the Electric Pulp Tester, leading to a false negative response. This means that even though the tooth is not responding to the EPT, there may still be an underlying issue with the nerve due to the trauma. Options A and B are incorrect because a false positive or true positive response would imply normal sensitivity of the tooth to the EPT, which is not typically seen in a recently traumatized tooth. Option D is not the correct answer because a lack of response to the EPT in a recently traumatized tooth does not mean that there is no issue present; it simply indicates a false negative response due to nerve injury.
