[Edit this paragraph] Suggestions
When people catch a cold, feel depressed, feel tired or have decreased immunity, the virus is easy to attack and cause oral ulcers. If you want to stay away from oral ulcers as soon as possible, please pay attention to the following suggestions. 1. Many people with oral ulcers get sick or get worse after overwork, especially modern people have a tight life and great mental stress. Oral ulcer can be said to be a "civilized disease" caused by poor living conditions, so it is very important to decompress, relax, avoid overwork and ensure adequate sleep. 2. When a cold is prevalent in winter, it is recommended that you drink a few packs of Radix Isatidis to kill the cold virus and prevent oral ulcers. If you have oral ulcer, you can rinse your mouth with light salt water or tea to keep your mouth moist, which is beneficial to its treatment. 3. There are more women suffering from oral ulcers than men, especially on the eve of menstruation, indicating that the occurrence of oral ulcers is related to estrogen in women, that is, once estrogen in the body is reduced, it is easy to suffer from oral ulcers. Therefore, female friends must pay attention to maintenance, don't lose too much weight, eat enough protein in their daily diet, and often eat natural foods that can supplement estrogen, such as soybeans and onions, to maintain the normal secretion of estrogen in the body. If you have an oral ulcer after trying a new toothpaste or eating something you haven't eaten before, consider whether it is caused by allergies and stop eating immediately. In addition, it is recommended to rinse your mouth with warm water, and then apply a small amount of raw honey to the ulcer surface. Repeatedly, the ulcer will be significantly improved the next day. 5. Oral ulcers are often accompanied by constipation and bad breath. Pay attention to smooth defecation. Eating more fresh fruits and vegetables and drinking more water, with at least 1000 ml of water every day, can clean the stomach, prevent constipation and contribute to the recovery of oral ulcer. 6. Oral ulcers are mostly accompanied by vitamin B2 deficiency, and it is effective to treat them with vitamin B groups such as vitamins B2 and B6. All kinds of fresh fruits and vegetables are rich in vitamins and minerals. You can eat more yellow and dark green fruits and vegetables, and eat at least 500 grams of fruits and vegetables every day to supplement the vitamin deficiency. In addition, vitamin A and zinc should be supplemented by eating foods such as milk, eggs and wheat germ. 7. Oral ulcer is also considered as a sign of weakness, so you should not neglect to strengthen exercise and improve your physique. In short, "eight thousand steps a day, eight hours' sleep at night, three meals, eight kinds of vegetables and a lot of eight glasses of water" can not only keep you away from oral ulcers, but also keep you away from other diseases and keep you healthy forever. 8. Usually pay more attention to eating foods rich in vitamins.

[Edit this paragraph] Frequently Asked Questions
Does oral ulcer need surgery? Surgery is one of the routine means for western medicine to treat tumors and other diseases. Is this method also suitable for oral ulcers? There are many reasons for oral ulcers. As long as the stimulating factors are removed, the acute traumatic oral ulcer will heal quickly, and of course there is no need for surgery. Recurrent oral ulcers occur frequently and their locations are uncertain, so "coming and going in a hurry" is certainly not the indication for surgery. For those oral ulcers that do not heal for a long time, the area is obviously increased, the texture is hardened, and even the adjacent lymph nodes are swollen and the whole body is weak, we should be highly alert to their canceration. Under local anesthesia, we need to cut some diseased tissues and observe them under the optical microscope. This is called "pathological examination", not "operation". Only when the case section proves that the oral ulcer has become cancerous or severe epithelial dysplasia, surgery is needed. Therefore, surgery is not a routine treatment for oral ulcers. In addition, other non-surgical physical therapies, such as laser, cryotherapy and microwave, are more convenient than surgery. These methods can also be used for oral ulcer cases with exposed lesions and small areas. What is the relationship between oral ulcer and autonomic nervous system and immune system? In real life, when the work pressure is heavy, the psychological burden is heavy, and the mood is tense, people are often prone to get sick. What is the reason? Experts believe that this is the performance of the autonomic nervous system affecting the immune system. When the autonomic nervous system is dysfunctional, the immune system will also be dysfunctional, and then various intractable diseases will appear. For example, the normal activity of parasympathetic nerve can promote the secretion of saliva, gastric juice, intestinal juice, pancreatic juice and insulin. When the parasympathetic nerve activity is weakened and sustained, harmful bacteria in the oral cavity cannot be completely eliminated due to the decrease of saliva, which leads to chronic pharyngitis and oral ulcer that are difficult to cure. If the symptoms are mild, patients with autonomic nervous disorder can take some vitamin B 1 and oryzanol in moderation, which has a certain regulatory effect. If the symptoms are serious (such as immune system diseases), the effect of the traditional Chinese medicine prescription "neuroimmune agent" is very obvious, usually within 3 days. Which drugs are easy to cause oral ulcers? Drugs can also induce or directly lead to oral ulcers. 1. Eating too much throat-moistening tablets can also lead to oral ulcers, because throat-moistening tablets contain components such as mint or iodine, which have a direct stimulating effect on oral mucosa, just like the chemical stimulation of sulfuric acid on the skin. Therefore, when there is no inflammation in the mouth, don't eat too many throat tablets to avoid oral ulcers. 2. Antibiotics Many broad-spectrum antibiotics can induce oral ulcers, because ampicillin, cefalexin, metronidazole, tinidazole and other broad-spectrum antibiotics have a wide range of antibacterial activities, but lack of pertinence, which is easy to cause flora imbalance and fungi to grow, thus causing oral ulcers. If you find the above situation, you should consult a doctor in time and try to take other drugs instead. It is reported that antipyretic and analgesic drugs, such as aspirin and diclofenac sodium, can cause oral ulcers. Antipyretic and analgesic drugs are mostly organic weak acids, which have stimulating effect on mucosa and are prone to allergic reactions, leading to oral mucosal damage. In addition, chemotherapy drugs such as methotrexate and vincristine can also cause oral ulcers. Chemotherapeutic drugs are cytotoxic and oral mucosa grows rapidly. Therefore, chemotherapy drugs are also toxic to them, leading to oral ulcers. Why do oral ulcers often recur? Generally, the pain was relieved on the same day and recovered within 1 month. Why is there recurrence of oral ulcer? The etiology is not clear at present, but there are many factors that can directly lead to the occurrence of oral ulcer: infection of bacteria, viruses and other microorganisms; Malnutrition and vitamin deficiency; Effects of digestive system diseases, such as gastrointestinal ulcer inflammation, constipation and diarrhea; Lack of trace elements, such as iron deficiency, folic acid, B 12, zinc; Endocrine disorder; Mental and neurological factors, such as overwork, nerve fluctuation, nerve disorder, etc. Some women will have oral ulcers before or after each menstrual period, which can only be temporarily relieved by drug treatment. It will still appear as usual during menstruation next month, and the pain is unbearable. At the same time, it is often accompanied by annoying symptoms such as dry mouth, upset, irritability and dry stool. Clinical studies have found that oral ulcer during menstrual period is mainly caused by the increase of progesterone level and the decrease of estrogen (progesterone, etc.). ). Precautions for patients with recurrent oral ulcer: 1, eat less or no spicy or irritating food; 2. Strengthen physical exercise after healing to improve the body's resistance to diseases; 3. Eat more fresh fruits and vegetables and foods rich in vitamins; 4. Pay attention to the law of daily life, quit smoking and drinking, and avoid overwork and tension; 5. Maintain a good mood and oral hygiene, remove large pieces of tartar in time and remove bad prostheses; 6. Early detection and treatment of recurrent oral ulcers. What are the hazards of oral ulcers? Oral ulcer is a common symptom in daily life, which will be encountered more or less in people's life. Usually, oral ulcers can heal themselves after rest, diet adjustment and keeping the stool unobstructed. Some patients can be cured only by local medication or taking several kinds of traditional Chinese medicines, and generally will not have serious adverse consequences on the whole body. However, if one or more oral ulcers recur or even erupt one after another, and the pain is unbearable or accompanied by ulcers in other parts (such as vulvar ulcers), great attention should be paid, because such recurrent ulcers are likely to be an early warning signal of an immune disease-Behcet's disease. Behcet's disease is also called Behcet's disease syndrome or eye, mouth and genitalia syndrome. Oral ulcer, genital ulcer and iridocyclitis are common in clinic. Among them, eye symptoms are diverse, which can be manifested as blurred vision, decreased vision, eyeball pain, photophobia and tears, foreign body sensation and floaters. In severe cases, it can lead to blindness. In addition, there is eye reaction after needle injection. Without a comprehensive understanding of the disease, the symptoms may be described to doctors in different specialties when seeking medical treatment, which often leads to the situation of "treating the head with a headache, treating the foot with a pain" and losing the opportunity to receive the best treatment plan. Behcet's disease has existed since ancient times and can occur in both men and women. It can be seen at all ages, especially after the age of 35. Its occurrence and development are closely related to abnormal immune function. Traditional Chinese medicine calls it "the fox's confusion", and points out that "the erosion in the throat leads to confusion, and the erosion in the yin leads to the fox". The occurrence of this disease is closely related to the deficiency of liver and kidney, deficiency of both qi and yin, and exogenous damp heat. Over time, damp-heat and qi and blood beat each other, and dampness, toxin and blood stasis are intertwined, which leads to repeated attacks of the disease and is difficult to heal. Over the years, according to the traditional Chinese medicine theory and clinical practice, aiming at the different symptoms of Behcet's disease in acute attack and remission, methods such as clearing away heat and toxic materials, clearing away damp-heat, clearing away toxic materials and dredging veins, invigorating qi and nourishing yin, and tonifying liver and kidney have been used for treatment. The results show that traditional Chinese medicine can not only control the recurrence of ulcer, but also regulate immune function. In addition, according to the characteristics of small lesions and shallow parts, locally blow tin powder, ice boron powder, phellodendron amurense and Asari powder, gargle with honeysuckle and licorice decoction, and fumigate Flos Chrysanthemi Indici, Kochia scoparia and Sophora flavescens decoction in sitz bath. Clinical practice has proved that the treatment of Behcet's disease with topical Chinese medicine and oral Chinese medicine can alleviate the number, quantity and pain of ulcers in about one month, and the disease can be further controlled by continuing treatment for several months. In addition to medical treatment, we should also pay attention to protecting oral hygiene, eat more fruits and vegetables, eat less barbecue, fried and greasy food, and do not eat spicy and irritating foods such as pepper, raw onion, ginger, garlic, tobacco, wine and mutton. Avoid fatigue, keep a happy mood and have a smooth stool. Iron and zinc deficiency in the body is also prone to ulcers. Oral ulcer is the most common disease of oral mucosa, and its incidence is second only to dental caries and periodontal disease, accounting for the third place. Iron and zinc deficiency in the body can also cause ulcers. Recurrent oral ulcer is a polygenic genetic disease. When the body has gastrointestinal dysfunction, menstrual disorder, lack of trace elements such as iron and zinc, mental stress, fatigue or cold, it will induce oral ulcers, so vitamin B2 alone is ineffective. At present, there is no cure for this disease. Suffering from oral ulcer, you can eat fresh food rich in vitamins, protein and cellulose, pay attention to the combination of work and rest, remove inducing factors and reduce recurrence. How to stay away from oral ulcer in summer? Oral ulcer is a common disease of modern people. Most people think that getting angry in summer is easy to cause ulcers, but what is the real cause of oral ulcers? The doctor said that the causes of oral ulcers are nothing more than "vigorous heart fire" and "spleen and stomach heat accumulation". In addition to drug therapy, medicated diet therapy has a good effect. Oral ulcers are common in young adults and occur all year round. Especially in summer, the days are long and the nights are short, the temperature rises, people stay up late, and modern people are used to eating barbecue greasy food, which makes oral ulcers with heat constitution more likely to occur. Traditional Chinese medicine believes that oral ulcer has several types, such as vigorous heart fire, accumulated heat in spleen and stomach, excessive fire due to yin deficiency, deficiency cold in spleen and stomach, and liver cold invading the stomach. Besides medication, you can also use medicated diet. Strong heart fire or spleen and stomach fever can be treated with bamboo leaf porridge, which is made of fresh bamboo leaves, gypsum, rice and sugar. People with yin deficiency and excessive fire can be treated with winter porridge, which is made of San Qian Ophiopogon japonicus, San Qian Asparagus, San Qian Scrophularia, Miliang and rock sugar. Spleen-stomach deficiency-cold type porridge can be made from Radix Codonopsis, Zingiberis Rhizoma, Radix Glycyrrhizae Preparata, Poria, and brown sugar of glutinous rice. However, in addition to drug therapy and diet therapy, to avoid oral ulcers, we still need to pay attention to ordinary living habits, avoid spicy, fried, greasy and sticky food, drink more boiled water, eat more vegetables, keep the stool smooth and avoid constipation; Patients with severe aphtha can be replaced by soft or semi-liquid diet. What kind of oral ulcer must be biopsied? Biopsy is the abbreviation of biopsy, which is also the proverb "slice" Biopsy can confirm the diagnosis. Biopsy report can be said to be a medical "court" diagnosis, which is very authoritative. However, biopsy is an invasive examination after all, and it must have certain indications. Blind biopsy will only increase the patient's pain and will not help the diagnosis. So what kind of oral ulcer must be biopsied? Generally speaking, most oral ulcers are benign, with regular shape and certain regularity of attack. However, some oral ulcers do not heal for a long time, the pain is not obvious, the edge is uneven, the base is uneven, it is granular, the texture is hard and tough, not as soft as normal mucosa, and the boundary with the surrounding normal mucosa is unclear, which is often a signal that the ulcer begins to become malignant. Biopsy should be performed as soon as possible to clarify the nature of ulcer and provide early anticancer treatment. In addition, when it is not clear whether oral ulcer is a rare disease such as tuberculous, small salivary gland tumor, granulomatous, etc., it can also be diagnosed by biopsy. What are the "hair products" that cause oral ulcers? Clinical experience and common sense of life tell us that the occurrence of oral ulcer has a certain relationship with diet. Summarizing the personal experience provided by patients with recurrent oral ulcer, the following foods may be related to the recurrence of oral ulcer. People call these potentially pathogenic foods "hair" for short. Various pickled products: such as pickles, bacon, salted fish, etc. Especially the "old pickles" and "old bacon" that have been cured repeatedly or for too long. All kinds of bamboo shoots and bamboo shoot products: winter bamboo shoots, bamboo shoots, hairy bamboo shoots, dried bamboo shoots, etc. All kinds of smoked fried foods: smoked fish, chicken, meat and fried chicken legs, fried ribs and so on. Various wax products: bacon, ham, etc. All kinds of fried fruits: fried peanuts, fried melon seeds and so on. And pepper, pepper, vinegar, soju, ginger, garlic, pepper, coffee, mustard, onion and so on. Of course, "hair" often varies from person to person. Hair that threatens A may be harmless to B. Therefore, after reading this article, patients should not "avoid eating on a large scale". Instead, we should properly "avoid eating" according to our actual situation, otherwise it will easily lead to malnutrition and be unfavorable to the rehabilitation of oral ulcers. What is the relationship between oral ulcer and immunity? Oral ulcer mainly refers to the ulcer of oral mucosa. In stomatology, there is no clear conclusion about its cause, except that more than 90% of it belongs to "recurrent oral ulcer". In addition, the other two tissues in the mouth, gums and tongue, will also have ulcers, but the causes are not the same as those of oral mucosal ulcers, and most of them are related to inflammation caused by excessive internal heat. The main symptom of "recurrent oral ulcer" is recurrent attack, and the frequency of attack has certain regularity. More than once a month is more frequent, usually once every two or three months, with a peak of seasonal attacks. Generally, the period from onset to recovery is between 7~ 15 days. The pain is unbearable at the time of onset, and there is basically no sequelae after recovery, but it cannot be taken lightly, because it is not clear whether it will turn into "lichen planus" (belonging to histiocytic variation). This ulcer is also related to inflammation, but it is by no means caused by excessive internal heat! Generally speaking, the medical view holds that this is a phenomenon of vitamin deficiency, and we support this view. But the problem is that taking a lot of vitamins in clinic can sometimes alleviate the condition, but the overall treatment effect is not good. According to the research, this phenomenon, like gingival atrophy, is caused by local nutritional deficiency. Lack of local nutrition can lead to low local immunity. A virus that can cause ulcers lurks in the oral mucosa for a long time, but the mucosa loses its resistance to it due to local nutrient deficiency, resulting in ulcers. Because this kind of ulcer is not inflammation caused by bacterial infection, it is not getting angry, so it is not ideal to directly use antibiotics and anti-inflammatory drugs or take Chinese medicine to get rid of the fire on the ulcer surface, which is often counterproductive. Patients with oral ulcer should not eat watermelon. Summer is coming, the heat is unbearable, and they are prone to oral ulcers. Some patients think that watermelon is rich in water and vitamins, and it must be the best food to relieve and treat oral ulcers. Actually, it's not like this. Watermelon can aggravate oral ulcers. Traditional Chinese medicine believes that the main causes of oral ulcer are yin deficiency and internal heat, and deficiency fire disturbs people. Watermelon has diuretic effect. If people with oral ulcer eat more watermelon, the water normally needed in the body will be discharged through the diuretic effect of watermelon, which will aggravate the state of yin deficiency. In addition, watermelon has a high sugar content, which is also easy to prolong the healing time of ulcer surface. In addition, people with deficiency of spleen and stomach should not eat more watermelons. Watermelon is a cold product. Eating too much is easy to hurt the spleen and stomach, and there are symptoms such as bloating, diarrhea and loss of appetite. People with renal insufficiency should not eat it. Eating watermelon in a large amount in a short period of time makes the water in the body increase sharply, which exceeds the physiological capacity of the human body and increases the burden on the kidneys. Especially in patients with renal insufficiency, the ability of kidney to regulate water is greatly reduced, and too much water entering the human body can not be excreted in time, resulting in a sharp increase in blood volume and easy to induce acute heart failure. How to self-care for oral ulcer? If there is an ulcer, you should first go to the stomatological hospital for examination and diagnosis and take effective treatment measures. Also note the following points: 1. Avoid and eliminate all local stimulating factors; 2. Patients emphasize quitting smoking, drinking and avoiding spicy and irritating diet; 3. Live a regular life, feel comfortable, strengthen physical exercise and improve the body's disease resistance; 4. A reasonable diet should be light and digestible, rich in calories and protein, and eat more fresh vegetables and fruits; If the patient's diet is inconvenient, nasal feeding can be used; 5. Do a good job in psychological care. Due to repeated injuries for a long time, patients often lose confidence in the cure and even worry about their life, work and future. Patients should be encouraged to establish the determination and confidence to overcome the disease; 6 regular review, once found to have a tendency to cancer, should be timely and active treatment. 7. For general ulcers, drugs such as tin powder, green plum powder and ulcer patch can also be applied locally. What are the diseases that may lead to baby's oral ulcer? There are many reasons for baby's oral ulcer, and the common ones are as follows: hand, foot and mouth disease-this disease also has symptoms similar to herpetic stomatitis, which is popular in children under 5 years old. After the illness, oral lesions spread all over the lips, cheeks, tongue, palate and other places, and there are many small blisters, which are easy to rupture and form multiple small ulcers. In addition to the oral cavity, scattered blisters can also appear on the skin of palms, soles and buttocks, so it is called hand, foot and mouth disease. Aphtha-It's very common, but the cause is different. Some are caused by wounds that are not obvious in oral mucosa, some are caused by excessive pressure, and some are caused by lack of vitamin B in food. At first, the oral mucosa will feel burning, and then it will turn red, forming many small ulcers, which is quite painful. The common parts are tongue mucosa, floor of mouth and tongue. Trauma-all burns, stab wounds, eating corrosive things, etc. , will cause oral mucosal damage, and then lead to ulcers. Drug allergy-babies with special constitution may cause the so-called "erythema multiforme" due to unknown reasons such as drugs or infections. At this time, the baby will have the target erythema, and the eyes, lips, mouth and urogenital tract will be inflamed and ulcerated. It is worth noting that the baby's oral ulcer may sometimes be related to its mental factors. For example, if the baby is too excited or worried about something, it will promote the occurrence of aphthous ulcers. Also, using some toothpaste containing spices or applying some irritating drugs can also cause baby's oral ulcer.
[Edit this paragraph] Dental ulcer care of denture installers
Clinical cases show that improper and incomplete denture cleaning methods are easy to produce odor, tartar and plaque, which will lead to oral ulcers. Coupled with loose dentures and chewing pain, it will directly affect diet, reduce gastrointestinal function, and even lead to oral cancer and visceral diseases, with very serious consequences. The nursing care of patients with denture inlay oral ulcer is different from that of patients with common oral ulcer. Statistics show that even if the denture is made well, it is difficult to fit the mouth100%; Middle-aged and elderly people have less saliva and low viscosity, and the annual deformation of alveolar bone will lead to loose dentures and weakness in wearing; When eating with dentures, food residues are stuffed between dentures and gums, which directly affects eating; If the alveolar bone is severely absorbed and flat, the denture cannot be worn firmly. Therefore, based on these objective factors, the medical community agrees that oral ulcers of denture restorers are mainly caused by improper nursing and improper denture restoration, so targeted professional nursing is needed. At present, the general knowledge of denture care is not very popular in China, which leads to the lack of scientific and effective denture care for middle-aged and elderly consumers in China. Except for a few people who can buy such products from abroad, most people use simple "indigenous methods", such as cleaning with blisters, toothpaste and toothbrushes, and there is no way to keep their dentures. Therefore, the cases of oral ulcers caused by unclean and unstable dentures in middle-aged and elderly people are increasing year by year. There are few safe, convenient and effective denture care products on the market at present. In China, only Jacqueline has passed the CE certification of the European Union and launched a series of denture supporting products. Combined with expert advice and internationally accepted nursing methods, the denture nursing concept of "taking, soaking and sticking dentures every day and scientifically protecting dentures" is put forward, which has obvious preventive effect on dental ulcer of denture wearers. The true face of oral ulcers The reason why most people have recurrent oral ulcers is because the blood vessels in the body are blocked. When the oral mucosa is destroyed by bacteria, it cannot be repaired in time because of blood vessel blockage. Causes oral ulcers to occur frequently and last for a long time. The reason why blood vessels are blocked is that most people are weak in constitution and have deficiency of both kidney and spleen. Western medicine and some so-called drugs specially used for the treatment of oral ulcer mostly relieve pain directly when the ulcer breaks out, but because it does not solve the fundamental problem of oral ulcer, it will not fundamentally cure oral ulcer. Therefore, people with frequent oral ulcers should not go to western medicine hospitals to treat oral ulcer diseases, but should go to Chinese medicine departments with certain technical level and experience in oral ulcer treatment. In particular, it is necessary for Chinese medicine doctors to diagnose and treat the cold and heat of personal constitution and the function of kidney and spleen. Then the kidney and spleen need medical treatment. When the kidney and spleen are healthy, the blood vessels are unobstructed, and the body's resistance and ability to recover in time are enhanced, then the problem of oral ulcer will rarely appear again, and even other physical problems will rarely appear. For people with deficiency-cold constitution and weak kidney and spleen, we should pay attention to eating more foods that tonify the kidney and strengthen the spleen and eat less cold foods. For example, you can eat more ginger, onions, black beans, shrimp, leeks and so on. And eat less cold foods such as bitter gourd and watermelon, and pay special attention to the local dishes at that time. Drink less or no cold beer, cold drinks, etc. And eat less spicy, barbecue, hot pot and other irritating foods.
