HPV is the fundamental risk factor for cervical cancer. However, oral papillomavirus infection can be related to lesions within the mouth and throat. Find out more here.
Human papilloma viruses (HPV) are a part of it Papillomaviridae family that’s able to infecting different species. More than 100 kinds of HPV have been described in humans that affect the skin or mucous membranes. In this text, we are going to take a better take a look at papilloma within the oral cavity.
The oropharyngeal area is considered one of the fundamental sites of this virus within the body. In fact, infections of this kind have incidence has increased in recent times. What are its fundamental causes? How to detect it? Find out here!
About the Human Papilloma Virus (HPV)
HPV is split into two fundamental groups, depending on the oncogenic capability of the lesions it causes. High-risk viruses are those involved in the event of cancer.
Meanwhile, low-risk HPV includes viruses that cause lesions which can be considered benign, resembling warts or warts. Determining the sort of virus present within the lesion requires specialized tests.
Causes of papilloma within the oral cavity
The fundamental source of HPV infection is sexual activity. Therefore, it is assessed as a sexually transmitted infection (STI). In fact it’s essentially the most common viral sexually transmitted disease on the earth.
Oral papilloma is less common than within the anogenital area; that is attributable to regular oral sex. In addition, other non-sexual routes of infection are also possible.
In newborns, the birth canal is an important source of infection. Similarly, it is usually possible to cross the placenta and go through the amniotic fluid.
On the opposite hand, autoinoculation by which a change in one region of the body may function a source of infection elsewherehas also been described.

Risk aspects related to oral HPV
Several studies have identified certain aspects that increase the likelihood of HPV infection. Although the literature is more extensive regarding anogenital infections, oral papilloma can be related to individual behaviors considered dangerous.
In addition to oral sex a few of the aspects involved in HPV transmission are as follows:
- Early initiation of sexual activity
- Numerous sexual partners
- Unprotected sexual activity
- Smoking
- Habitual alcohol consumption
- History of infection with other HPV types
Since then, gender has also been cited as a risk factor by some authors a better incidence of oral HPV is observed in men than in women. However, it is feasible that this difference is said to the upper consumption of alcohol and tobacco by men, in addition to the age of onset of sexual intercourse.
How does HPV infect people?
The virus particles must enter the epithelium to contaminate it. For this reason, it was established that there have to be a previous lesion within the skin or mucosa where the HPV is regarded as situated.
However, these wounds are often microscopic. Thus, each microtrauma can function a gateway to virus infection. The oral cavity is a region vulnerable to this kind of injury.
This need for prior trauma is caused HPV is simply in a position to infect cells within the deepest layer of the squamous epithelium, present in the skin and mucous membranes. Therefore, only in these places can papilloma be observed.
The deeper layers supply cells to the outermost layers as basal cells proliferate and migrate to the surface. In this fashion, the HPV-infected cell penetrates the complete thickness of the epithelium.
Clinical signs of HPV within the oral cavity
In most cases, HPV infection is asymptomatic and will go unnoticed. However, the changes it causes have characteristics that allow dentists and doctors to acknowledge it. Its fundamental clinical manifestations are described below.
Oral papilloma
It is small (lower than one centimeter in diameter) and frequently a single lesion. It is situated on the tongue, taste bud, uvula, frenulum or cinnabar. It has a cauliflower-like appearance, with a light-weight pink or white coloration.
It is normally painless and its growth is rapid. This is attributable to strains with low oncogenic risk. It affects people of all ages, but is more common between the ages of 30 and 50.
condyloma acuminata
This lesion is barely larger than the oral papilloma (as much as 3 centimeters). It has a cauliflower-like appearance and will be single or multiple. When the latter occurs, the tendency is to group lesions together.
Condyloma acuminatum is said to the low oncogenic risk subtypes (HPV-6 and HPV-11), but transmission of this infection is sexual.
Multifocal epithelial hyperplasia
Whereas in multifocal epithelial hyperplasia or Heck’s disease, the lesions usually are not rough, although they seem raised. Growth is slow and coloration is normally similar to in location.
There are lots of them and they typically appear on the lips or on the lateral fringe of the tongue. It mainly affects children.
Prevention of papilloma within the oral cavity
Because symptoms can go unnoticed, the prevalence of HPV infection is high, making it difficult to take effective measures to avoid infection.
Even so, the fundamental prevention relies on the acquisition of responsible sexual behavior. In this regard, sex education from an early age is important.
Vaccines and oral papilloma
Vaccines have been developed to stop infection with certain kinds of HPV, especially those related to the event of cancer. For this reason, the best effectiveness of their administration is observed before the beginning of sexual life, because the potential for infection before vaccination is negligible.
Current HPV prevention options are as follows:
- Gardasil, manufactured by Merck Laboratories. It protects against HPV types 6, 11, 16 and 18 and is effective in stopping cancer and warts.
- Cervarix by GlaxoSmithKline. Provides protection against HPV strains 16 and 18, that are involved in the event of cervical cancer.
- Gargard 9from MSD. Provides resistance to types 6, 11, 16, 18, 31, 33, 45, 52 and 58.

Link between HPV and oropharyngeal cancer
HPV is the fundamental risk factor for cervical cancer. However, it is usually implicated in cancers of the anogenital area and the oropharynx.
Of the oncogenic HPV types present in squamous cell carcinoma of the pinnacle and neck, HPV 16 is essentially the most common. However, unlike cervical cancer, more oropharyngeal research is required characterize this region.
