Oral HPV

Oral HPV infection may be associated with different diseases of oral cavities. HPV (Human Papilloma Virus) is one of the most prevalent infections in the world with several millions of new cases diagnosed yearly. HPV infection usually is present in the epithelial membranes of different parts of the body and may cause abnormal changes in the infected cells. There are more than 100 HPV types and about 30 of them have been identified in the oral cavities. 

Although oral HPV infection occurs frequently, it rarely causes lesions. An increased rate of oral HPV-induced lesions is observed in people with an impaired immune system, especially in HIV-positive persons. The most common conditions induced by oral HPV infection are focal epithelial hyperplasia, oral condylomas and oral papillomas. Oral HPV infection has been found to be associated with some cases of oropharyngeal cancer, but it is not the main risk factor for this kind of cancer. 

In general, it is not well-known how HPV infection gets into the oral cavities. There was a lot of scientific research which tried to clarify this problem. It is estimated that oral-genital contact is the main way of transmission for oral HPV infection. HPV can also be transmitted through mouth-to-mouth contacts and from infected mother to the newborn at the time of delivery. 

Oral HPV infection may develop in children born from HPV-infected mothers. In the majority of these cases HPV infection goes away on its own, but sometimes it can be chronic and cause recurrent respiratory papillomatosis (RRP). This condition is characterized by the presence of benign tumors (papillomas) in the upper and lower respiratory tract. The papillomas may be removed surgically, but they often reoccur, that is why the treatment of this disease is rather difficult.

Most often HPV lesions appear on the lips, but they have also been reported on the buccal mucosa, the tongue, the gingiva and the palate. At the same time, it should be noted that in most cases oral HPV infection is asymptomatic. Oral HPV-related lesions occur rarely, but the majority of them are associated with genital HPV types. This fact confirms that oral sex is a factor of an increased risk for oral HPV infection.
