What is dental equipment?
Cold sores and fevers are caused by herpes simplex virus 1 (hsv-1), which is transmitted from person to person by direct contact with infected skin or secretions, including saliva. These sores usually appear on small bubbles on the lips. Hsv-1 can lead to a similar, but smaller, blister that quickly becomes an ulcer (top of the mouth) in the mouth.
The first hsv-1 invades the skin, which causes a major infection, usually in childhood or adolescence. It can cause fever, mouth pain and sore throat. Primary infections are usually similar to other viral or bacterial throat infections and are usually not diagnosed with hsv-1 infection.
After the primary infection subsides, the virus has been dormant in the nerve root near the affected area of the skin. In some people, the virus is active from time to time, causing a new active ulcer on the skin, usually on the lips. These ulcers are known as cold sores or fever blisters, because the virus can be reactivated by a cold or fever. The virus can also be triggered by other factors, including stress, lip trauma, exposure to uv rays in the sun, menstruation, and suppression of the immune system.
In addition to causing oral infections, hsv-1 can also be transferred to the eyes, finger skin, genital area and other places. Most genital herpes infections are caused by herpes simplex (hsv-2), but hsv-1 can cause genital infection in some people. HSV - 1 May be due to other health issues (cancer malnutrition, or weakened immune systems, including HIV/AIDS) or for cancer chemotherapy, corticosteroids, or drug treatment, result in abnormal serious diseases, in order to prevent organ transplant rejection.
Hsv-1 infections are common in the United States, and most people are infected in adulthood. Even if we don't remember a primary hsv-1 infection in childhood, we occasionally have symptoms of a cold or fever indicating that hsv-1 exists.
symptom
Primary herpes infection - for the first time a human infection causes fever, headache, nausea, vomiting, pain, swelling and open sores in the internal of the gums and cheek, and painful throat infection is often mistaken for "sore throat", or another form of bacterial infection in the throat. These symptoms usually occur a week after exposure to hsv-1 patients.
Cold sores and fever blisters occur when the virus is reactivated later in life. They may occur during a period of illness or stress, malnutrition or sunlight, or no known cause. Dental procedures that stretch lips sometimes make the virus active. So far, the edge of the lip has been the most common place for these ulcers. They may occasionally erupt in the mouth, especially in patients with compromised immune systems or other medical conditions.
The first symptom of a cold sore is a vague tingling, burning or itching, followed by swelling and redness. Within 24 to 48 hours, one or more vesicles (" fever blister ") appeared. These blisters break, drain and form painful sores (" cold sores "), which are eventually covered with shells and scabs. When the wound heals, the shells fall off and form.
diagnose
Your dentist or doctor can usually diagnose cold sores and fever blisters by asking about your history and simply examining the area of your skin's infection. More complex diagnostic methods include virus culture, immunofluorescence (IF) or immunoperoxidase (IP) studies to detect hsv-1 in cells that have been scraped from infected areas. Complex tests are not always necessary in other healthy patients.
Blood tests can show that a person has a herpes simplex virus infection. However, the results of these blood tests usually don't come until the infection is gone.
Estimated duration
Symptoms of primary HSV - 1 infection may persist for one to two weeks. After the infection subsided, hsv-1 was dormant in the patient's nerve cells. A cold sore and a fevered blister usually form a shell within four days, fully healing within eight to 10 days.
prophylaxis
You can help prevent major herpes infections in children because they are not allowed to be kissed by anyone with a cold sore, a fever blister or a major herpes infection. However, despite these protective measures, most children are affected by hsv-1 in adulthood. There are several different vaccines for HSV (type 1 and type 2), but these vaccines seem to protect people who have never been infected.
There is evidence that applying sunscreen on your lips can protect against cold sores and fever caused by sun exposure. For people with weakened immune systems, antiviral drugs can be used to prevent cold sores from forming. In some cases, your dentist or doctor may prescribe medications to prevent outbreaks of disease. If you know that you're going to encounter a known trigger (for example, dental treatment), pre-prescribed medications can reduce the chance of an outbreak.
handling
Cold sores and fevers can be treated with antiviral drugs. If treatment begins after a blister occurs, the drugs are worthless. Antivirals directly applied to ulcers can shorten healing time. Oral antiviral drugs can help prevent colds in the tropics, because exposure to sunlight can cause disease. If your lips are too dry, wind and other weather conditions can also cause cold sores. It also helps to keep the affected areas clean, using soothing lipstick if the lips are involved. When you have blisters and ulcers, try not to touch the affected area and avoid kissing anyone.
When do you call professional dental supplies
Fever bubbles occur in about 25 to 35 percent of the population, and there is usually no risk. However, in people who are immunosuppressed by drugs or diseases, cold sores can be serious and life-threatening. If the lips or oral ulcer persists, please call your dentist or doctor immediately, if they let you is difficult to say words or swallowing, if you fell ill with a fever, or pain associated with different or new blisters or sores.
