Herpes is a temporary and recurrent skin lesion caused by a virus called herpes simplex on the lips or around the mouth and even inside the mouth (gums and roof of the mouth). This virus exists latently in the body of most healthy and normal people. Studies have shown that 90% of adults are carriers of this virus by the age of 60, but only 40% of virus carriers show clinical manifestations during their lifetime. Herpes simplex virus usually enters the body in the form of a cold in the early years of childhood and settles in nerve nodes. Herpes simplex virus may wake up during a person's life for several reasons such as fever, sunburn, pain, surgery, trauma, lack of sleep, menstruation in women, and mental or physical stress, and reach the skin of the lips or oral mucosa through the nerve pathways and cause a lesion. In some people, simple activities such as mountain climbing or dental treatment sessions can also cause herpes; Therefore, the idea that "herpes is caused by the contamination of dental equipment or **Mashhad orthodontics**" is completely wrong. Herpes is completely different from plague and even the places where they occur are different. Herpes viruses infect nerve cells and may secretly become dormant in nerve cells. As a result of stimulation (such as stress, an underlying disease such as a cold, etc.), the virus turns from a dormant state to an active state. The virus returns to the skin through nerve axons, where it multiplies and causes herpes. On average, up to three times a year, herpes can be observed in people carrying the virus as the virus becomes active. The place of herpes recurrence is constant throughout the life of each person and always involves a specific place, for example, it always appears on the right side of the person's lip. **Stages of herpes outbreak** First, you will feel itching or tingling in the place, then redness, swelling and brief discomfort will occur. After that, a cluster of small blisters usually appear and gradually they will give way to painful wounds. The wounds become dry and crack and bleed, and at the end, a brief and red swelling is created and disappears. Herpes will heal on its own within 1-2 weeks without any special treatment. The main problem caused by herpes, especially in women, is the category of facial beauty, which is also temporary. If a person's immune system is healthy, the occurrence of herpes is not a concern, but in patients with a weak or suppressed immune system, such as those with leukemia, hepatitis, organ transplant recipients, or patients undergoing cancer chemotherapy, a simple herpes can spread or not heal on its own, causing a lot of discomfort. Herpes can cause serious problems in babies and elderly people. **Read more" Familiarity with cleft palate and its treatment steps** **Is it possible to perform dental procedures when herpes occurs?** Be patient in case of symptoms, this lesion is limited in healthy people and will heal by itself. It is best to cancel any dental treatment until symptoms improve. In the case of patients who are undergoing fixed orthodontic treatment, it is recommended to consult an orthodontic specialist for the use of their orthodontic device. Do not have oral contact such as kissing. Separate your food, drinks, personal items such as toothbrushes and towels from others. There are two groups of dental clients. Emergency patients who come with severe and uncontrollable pain and are suffering from herpes can be treated in emergency treatment centers with infection control as much as possible. Sometimes antiviral drugs are also prescribed and used for these patients. But there is no such compulsion for normal clients. Their treatment time is canceled until their herpes heals (which can be determined by the sore drying or its complete disappearance). In this way, the risks of spreading the virus in the medical environment are eliminated. For dentists, it also has complications for patients with herpes and can cause a type of finger ulcer (called herpetic vitello). People who have a history of herpes, before going to the dentist, should take the pill to prevent the activation of the herpes virus every six hours, because this virus is in their body and is activated during contact and pressure of dental procedures. Since the pressure applied on the lips can lead to the activation of herpes, it is better for people who have a history of herpes to take a pill to prevent the activation of the herpes virus every six hours before going to the dentist, because this virus is present in their body and will be activated in the contact and pressure of dental procedures. **What causes us to get herpes?** As mentioned, the main cause of this condition is a virus, but this virus remains latent in the nerves and is sometimes reactivated and causes wounds. In mental or physical stress, the incidence of herpes increases. Pregnancy or menstruation, immunodeficiency, cold, sunlight, excessive fatigue, cold, sunlight, and dental or surgical procedures may be the factors that initiate the reactivation of the virus. Dental practices are among the things that are caused by the stress before the patients visit (which, of course, this type of stress is unnecessary: and the physical stimulation of the oral tissues during work, can be a powerful trigger for the occurrence of herpes. This condition usually resolves itself between two to three weeks after its onset in healthy people. But in immunocompromised patients, viral treatment is sometimes considered for herpes. Those who after visiting the dentist or before visiting (due to (stress) can use medicines preventively in consultation with their dentist. **prevention and treatment of herpes** Although cold sores cannot be cured or completely prevented, there are ways to reduce the frequency of outbreaks or limit their duration. It is possible to prevent people who are not infected with the virus by observing personal hygiene, controlling severe infection, and removing any triggers of the virus (such as stress, sunlight, etc.). When the wounds are painful, pain relievers such as ibuprofen, acetaminophen, etc. can be used to reduce the pain. Aspirin should never be used for pain control in children. Herpes can spread to others by kissing, so it is better to kiss someone when you have herpes. It is also better to use separate forks, glasses, spoons and utensils until your cold sores have healed. If a person does not get herpes at all, but gets infected with this virus in dentistry, it shows that the dental equipment was infected with the herpes virus, but the most common causes of herpes infection are not related to dental equipment, but due to the pressure and action that occurs during dental procedures. There are two types of treatment for herpes. Special creams for people who frequently get cold sores. Polio vaccine is also used to prevent herpes virus. Avoid people who are at risk, such as infants, the elderly, and people with compromised immune systems. If a person does not get herpes at all, but gets infected with this virus in dentistry, it shows that the dental equipment was infected with the herpes virus, but the most common causes of herpes infection are not related to dental equipment, but due to the pressure and action that occurs during dental procedures. People who often get herpes usually know the place of occurrence and its initial symptoms well, so if they are diagnosed in the early stages, they can reduce the severity of the symptoms with the use of topical ointments and oral anti-viral drugs (prescribed by a doctor). Experience has shown that a cold compress on the herpes site before the appearance of blisters and sores will also help control symptoms.
