Human papillomavirus infections are common, and are believed to be a significant cause of cancers of the oral cavity and throat. According to the United States Centers for Disease Control and Prevention (CDC), approximately 20 million Americans are infected with human papillomavirus (HPV), and another 6 million will become infected each year.
Oral human papillomavirus (HPV) infections are acquired via oral-genital contact, with oral sex being the greatest risk factor. While not all 40 types of sexually-transmitted HPV cause serious health problems, HPV is thought to be responsible for 25% of mouth cancers and 35% of throat cancers. Both boys and girls can be vaccinated against the highest-risk strains of HPV, and this is now recommended by the United States Centers for Disease Control and Prevention and American Academy of Pediatric Dentistry. The strains are grouped into cutaneous and mucosal types (cutaneous relates to the skin; mucosal relates to mucous membranes, such as the lining of the mouth). An HPV infection can trigger lesions, which may be located in any region of the ororespiratory tract, including the oral cavity, nasal passages, esophagus and larynx.
The incidence of tonsillar and base-oftongue cancers in the United States has increased annually since 1973, which may be due to changes in sexual practices (namely, the increased popularity of oral sex). Due to their role on the team, dental hygienists are particularly well suited to identify potential HPV lesions — and knowing what to look for is vital to early detection. A number of oral cancer screening technologies are available to aid in early detection (see sidebar).
Patients without evidence of a lesion but who test positive for HPV should be retested to look for a persistent HPV infection.
The Oral Cancer Foundation (oralcancerfoundation.org) is celebrating April as Oral Cancer Awareness Month by encouraging the dental community to offer free oral cancer screenings to the public. According to the Oral Cancer Foundation, new cases of the disease, worldwide, exceed 640,000 annually. The following note is placed in the patient’s chart when a wart is found in their mouth. Genital human papillomavirus (also called HPV) is the most common sexually transmitted infection (STI). The patient was made aware that they have a wart inside their mouth and therefor could be elsewhere.


ADA CERP is a service of the American Dental Association to assist dental professionals in identifying quality providers of continuing dental education. Most of these people do not know they have it,1 and though HPV is considered a common virus, it poses a serious public health threat — in no small part because it appears to be linked to cancers of the oral cavity and throat. The vaccines are most effective when completed before the first sexual contact has occurred. Cutaneous types cause common warts, while select mucosal strains are believed to be associated with oral cancer.
Dentists and dental hygienists play an important role in locating these lesions during routine examinations.
Oral cancers that are diagnosed early have a 80% to 90% cure rate, but, when discovered later, the cure rate drops to 45% at 5 years postdiagnosis.8 These figures underscore the importance of early detection via routine screening during oral exams. If the lesion is cancerous, treatment and follow- up procedures will be based on the stage of the disease. Sharuga, RDH, PhD, is a professor of dental hygiene in the Department of Allied Health Sciences, College of Public and Allied Health Sciences at East Tennessee State University (ETSU) in Johnson City, Tenn.
Among the partners supporting Oral Cancer Awareness Month activities are the American Academy of Oral and Maxillofacial Surgery, American Dental Association, Academy of General Dentistry and American Academy of Oral Medicine. Oral human papillomavirus infection in adults is associated with sexual behavior and HIV serostatus. These are all viruses that can be passed on during sex, but they cause different symptoms and health problems. Rarely, these types can also cause warts in the throat — a condition called recurrent respiratory papillomatosis or RRP.
This happens to the real life where people wants to get their cracking old teeth in order not to experience tooth ache and etc. ADA CERP does not approve or endorse individual courses or instructors, nor does it imply acceptance of credit hours by boards of dentistry. It makes sense, then, that dental sales professionals should be conversant about what clinicians can do in terms of early detection and treatment, as well as the tools that may help the dental team in these efforts.
An HPV infection is potentially dangerous because it can cause healthy cells to develop abnormalities.


Benign oral lesions caused by HPV include squamous papilloma, verucca vulgaris, condy loma acuminatum and focal epithelial hyperplasia. Clinically, lesions can be the same color as the surrounding tissues or appear white — depending on the amount of keratin present.
Sales consultants should advise their clinical customers that salivary diagnostic testing can detect the presence of HPV in the absence of a lesion.12 Any patient who is known to have the virus but does not present with lesions should receive frequent intraoral exams to ensure that subsequent lesions are detected and treated early.
In determining the need for screening, patients should be questioned about behaviors that may put them at risk of HPV infection — and approaching this topic with respect and confidence will help ease the discussion. Tabitha Price, RDH, MPH, is an assistant professor and preclinic coordinator in the dental hygiene program at ETSU. Unfortunately, most of these cancers are not found until later stages, in which case the survival rate drops to 30%. In most cases, the body fights off HPV naturally and the infected cells return to normal1 — but when the immune system is unsuccessful in eliminating HPV, visible changes will occur. In addition, educating patients about the prevalence of HPV and its relationship to oral cancer provides an opening for conversations about personal risks and the importance of regular oral cancer exams. Deborah Dotson, RDH, PhD, is an assistant professor of dental hygiene and interim dental hygiene program director at ETSU. Thanks to free screenings available in April last year, more than 50,000 people were screened, and organizers hope to double that number this year. These types can also cause other, less common but serious cancers, including cancers of the vulva, vagina, penis, anus, and head and neck (tongue, tonsils and throat). The types of HPV that can cause genital warts are not the same as the types that can cause cancer. There is no way to know which people who get HPV will go on to develop cancer or other health problems.
