If the woman with the h/o cervical dsyplasia how can you determine what caused it or if it's hpv. And I she had HPV in the mouth what symt. Would show?

Cervical dysplasia. Our assumption is that it is hpv. You can request hpv testing. The next most likely cause is tobacco use. I'm a gyn, so you may want to ask the oral hpv with an ENT or oral surgeon.
