Which of the following could mimic pulpitis pain?

Herpes zoster (shingles), when it involves a branch of the trigeminal nerve, classically causes severe, often unilateral facial/dental pain that can precede the appearance of the characteristic vesicular rash — this pre-eruptive neuralgic pain can closely mimic odontogenic/pulpal pain and lead to misdiagnosis. HSV (cold sores), HPV, and Coxsackievirus (hand-foot-mouth, herpangina) do not typically present with this kind of dental-pain-mimicking neuralgia.
