Oral ulcer, commonly known as "aphtha", is a superficial ulcer that occurs on the oral mucosa. From rice grains to soybeans, it can be round or oval in size. The ulcer surface is sunken and the surrounding area is congested, which may cause pain due to irritating food. It usually heals itself in a week or two. Oral ulcer occurs periodically and repeatedly, which is called "recurrent oral ulcer" in medicine. It can occur several times a year, or several times a month, or even new and old lesions appear alternately.
How to distinguish between oral ulcer and erosion
Although oral mucosal ulcer and erosion are common symptoms in oral mucosal diseases, they are completely different. First of all, erosion is different from superficial ulcer in clinical manifestations. Oral ulcers can be caused by systemic or local factors. Although all kinds of ulcers are epithelial or subepithelial, shallow or deep, acute or chronic, benign and malignant, they are all concave. Regular shape, round or oval; The boundary is clear, and it is "clear in latitude and longitude" with the surrounding normal mucosa. However, oral erosion is characterized by hyperemia, erosion flush with the surface of normal mucosa, no depression, covered with exudative pseudomembrane, various shapes and irregular boundary with surrounding normal mucosa. Secondly, the course of disease and prognosis are different. Ulcer generally has a short course of disease, and once it is cured, it will be "crisp and neat". Superficial and benign ulcers have no scars after healing except muscular ulcers and malignant oral ulcers. Erosion generally has a long course of disease, which is repeatedly prolonged and the healing process is "slow", but erosion generally does not leave scars. Finally, they behave differently under the microscope. Ulcer is characterized by the interruption of epithelial continuity, erosion is superficial, and epithelial continuity is not interrupted. When ulcer and erosion are atypical, it will be difficult to distinguish them, but generally speaking, they can be distinguished as long as they are carefully observed. It is worth mentioning that these two diseases can be transformed into each other or both exist at the same time.
How to prevent oral ulcer?
Oral ulcer is largely related to personal physique, which is unlikely to be completely avoided, but if the inducing factors are avoided as much as possible, the incidence rate can still be reduced.
Specific measures are:
1, pay attention to oral hygiene, avoid damaging oral mucosa, avoid spicy food and local irritation.
2. Keep a good mood, be optimistic and cheerful, and avoid things and troubles.
3. Ensure adequate sleep time and avoid excessive fatigue.
4. Pay attention to the law of life and balanced nutrition, develop certain defecation habits and prevent constipation.
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, non-surgical physical therapy such as laser, cryotherapy and microwave is more convenient and easy to operate, and these methods can also be used for oral ulcer cases with exposed lesions and small area.
How to distinguish benign ulcer from malignant ulcer?
In a person's life, the probability of oral ulcer is almost 100%. Oral ulcers do have the potential to become cancerous. Therefore, how to distinguish between benign and malignant ulcers is indeed a matter of concern to everyone. In terms of whether it will become malignant, a benign oral ulcer refers to an oral ulcer that will not become cancerous, while a malignant oral ulcer is the opposite. So how to distinguish between benign and malignant oral ulcers?
First of all, it is distinguished by the healing time of ulcer. Benign oral ulcers usually heal within a few days to weeks, while malignant oral ulcers develop progressively and do not heal for months or even years. Secondly, it can be distinguished by morphology. Benign oral ulcers are generally regular in shape, round, oval or linear, with neat and clear edges and clear boundaries with surrounding tissues. The sunken base is smooth and soft to the touch, and the pain is obvious. However, malignant oral ulcer has irregular shape, unclear boundary, uneven edge uplift and granular bottom, which is obviously different from normal mucosa, but the ulcer pain is not obvious. Third, it can be distinguished according to the course of disease. Benign oral ulcers often occur repeatedly and are self-limited, while malignant oral ulcers have no recurrence history. Once it happens, it won't heal. Fourth, the whole body can distinguish. The systemic symptoms of benign oral ulcer are rare, and the cervical lymph nodes are not swollen but not hard or adherent. Malignant oral ulcers are the opposite, and some even have cachexia. Finally, we can make a judgment according to the sensitivity to drugs. Benign oral ulcers generally have obvious effects after using anti-inflammatory and antiseptic drugs, and the healing is accelerated, while malignant oral ulcers often "ignore" drugs and have no obvious curative effect.
What is the cause of oral ulcer?
Modern medicine believes that recurrent oral ulcer is closely related to immunity at first. Some patients show immune deficiency, and some patients show autoimmune reaction, that is, due to various factors, the normal immune system of the human body produces immune reaction to its own tissue antigen, causing tissue damage, thus causing diseases. Secondly, it is related to heredity. Clinically, the incidence of recurrent oral ulcer has obvious familial genetic tendency. We often see that if one or more parents have recurrent oral ulcers, their children are more likely to get sick than the average person. In addition, the incidence of recurrent oral ulcer is often related to certain diseases or symptoms, such as digestive system diseases, gastric ulcer, duodenal ulcer, chronic or persistent hepatitis, colitis and so on. In addition, anemia, partial eclipse, indigestion, diarrhea, fever, lack of sleep, fatigue, mental stress, work stress, menstrual cycle changes and so on. With the activity, alternation and superposition of one or more factors, the immunity of the body decreases and the immune function is disordered, which also causes the frequent occurrence of recurrent oral ulcers.
Treatment of oral ulcer
Although there are many treatments for oral ulcer, they are basically symptomatic treatment, the main purpose is to relieve pain or reduce the number of recurrences, but the recurrence can not be completely controlled, so it is particularly important to prevent this disease.
Pay attention to keep your mouth clean, rinse your mouth with light salt water, quit smoking and drinking, live a regular life and ensure adequate sleep. Insist on physical exercise, have a light diet, eat more fruits and vegetables, eat less spicy and irritating food, and keep the stool smooth. Women should pay attention to rest before and after menstruation, maintain a happy mood, avoid excessive fatigue, have a light diet, eat more fruits, fresh vegetables and drink more water. , thus reducing the chance of aphtha.
It should be reminded that long-term unhealed ulcers in the mouth may become cancerous due to frequent stimulation of chewing and speaking. Especially in those parts that are in contact with teeth, if there are residual broken teeth that have not been pulled out, or the dentures are not made properly, their sharp edges will be constantly stimulated, which will scratch the mucosa and produce ulcers. If the stimulating factors are not removed, the ulcer will not heal, but will get worse day by day. This long-lasting ulcer may also be a precancerous lesion, which is very easy to become cancerous. If you often suffer from oral ulcers, you need to pay attention to the above problems.
If you have an oral ulcer, don't take it lightly. If you are suspicious, you should go to the hospital in time, and if necessary, do pathological examination and make a clear diagnosis before you do corresponding treatment. Don't be careless and delay the treatment opportunity.

Oral ulcers may hide various diseases for up to three weeks and must be carefully investigated.
Almost everyone has experienced small oral ulcers, most of which are caused by trauma. Professor Scully from the School of Dentistry, University of London, pointed out that if the oral ulcer lasts for three weeks, the cause must be found out.
About 20% people suffer from recurrent oral ulcers, which are round or oval with clear boundaries. 80% patients with ulcer diameter less than 5mm healed in 7 ~ 14 days. Larger ulcers are rare and take weeks or months to heal, and scars still exist. In addition, herpes ulcers need 1 month to be cured.
According to the Japanese Medical Tribune (2006 5 4 38+6 7 0), the cause of oral ulcer is unknown, and some patients are related to tension, trauma, smoking cessation, menstruation and food allergy. There is no special examination method, and we can only rely on the diagnosis of typical symptoms and history. But we can't ignore the differential diagnosis. Besides the deficiency of iron, folic acid and VitB 12, we should also consider whether there are immune disorders such as chronic inflammatory bowel disease, AIDS infection and neutropenia. In addition, systemic diseases and skin diseases such as leukemia, lupus erythematosus and Behcet's disease (see figure) should be excluded. Anticancer drugs and antithyroid drugs may also produce oral ulcers.
Single chronic ulcer should be suspected of oral cancer. Oral ulcer can also appear as an accompanying symptom when children have periodic fever, pharyngitis, hand-foot-mouth disease and infectious mononucleosis.
Professor Scully pointed out that oral ulcers can be treated with chlorhexidine or hydrocortisone sugar-coated tablets, and triamcinolone acetonide ointment is applied four times a day. If symptoms do not improve, systemic corticosteroids should be considered.
There are three types of oral ulcers.
Clinically, it can be divided into three types: recurrent mild oral ulcer, recurrent stomatitis oral ulcer and recurrent necrotic perigonadal mucosa.
Vitamins can treat oral ulcers.
Whether it is a single or chronic oral ulcer, vitamin B groups, such as vitamins B2 and B6, are effective. Some people even ate group B for one night, and the oral ulcer disappeared cleanly.
When vitamin B2 is insufficient, it will cause angular stomatitis, eye congestion and anal ulcer, especially on the skin and mucous membrane. Vitamin B6 is related to fat metabolism. When B6 is insufficient, it will cause seborrheic dermatitis. In addition, vitamin B groups, such as pantothenic acid and biotin (except B 1), also contribute to the prevention and treatment of oral ulcer under the mutual influence.
Why do oral ulcers often recur?
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.). ).
Oral ulcers are usually dangerous.
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.
Stay away from oral ulcers 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.
Three notes on prevention and treatment of oral ulcer
◆ Oral ulcers are not necessarily caused by excessive internal heat.
When it comes to oral ulcers, most people treat them with "getting angry", drinking herbal tea and taking anti-inflammatory drugs, which is one-sided. Generally speaking, the etiology of oral ulcer is not clear, and there are many factors related to the disease, such as psychosocial factors, genetic factors, infection factors, nutritional deficiency and so on. , can induce ulcers. In these cases, drinking herbal tea does not solve the problem.
Overeating can also cause oral ulcers.
Eating too much in cities is not unrelated to the occurrence of oral ulcers. Take rice as an example, the epidermis contains vitamin B2 and trace element zinc. However, in order to make rice look white and taste good, rice processors remove the surface layer of rice, resulting in the loss of the above nutrients. Eating too much rice lacks these nutrients and is prone to oral ulcers. Therefore, doctors remind people to eat more fruits and vegetables and supplement vitamin B2 and zinc gluconate.
◆ Recurrent ulcer is related to immunity.
For common recurrent oral ulcers, most people use topical drugs to repair them. Because there is no specific cause, even if it is effective temporarily, it will recur in the future.
Recurrent oral ulcer is closely related to immunity. Some patients show immune deficiency, while others show autoimmune disorder. In addition, anemia, partial eclipse, dyspepsia, diarrhea, fever, fatigue, work stress, menstrual cycle changes are also inducing factors. With the activity, alternation and superposition of one or more factors, the immunity of the body decreases and the immune function is disordered, which also leads to the frequent occurrence of oral ulcers.

Oral ulcer or related to tumor
In summer, many people will be troubled by oral ulcers. For this common disease, many people associate it with excessive internal heat and hot air, but they don't know that there are many causes of oral ulcer, and it may also be the manifestation of malignant tumor. Yesterday, the reporter learned from the Stomatology Center of the Second Hospital of Zhongshan that since the summer, the center has continuously treated three patients with chronic oral ulcers and was finally diagnosed as cancer.
Emotional irritability and ulcers often occur in summer.
Xiaoyun, 35, has suffered from oral ulcers for many years, and this summer is even more miserable. It's hot, I'm busy with work, I can't eat well and sleep well, but my mouth ulcer has come out and I can't eat when I feel pain. It was finally cured, and a new ulcer broke out in a few days.
Pan Chaobin, director of the Stomatology Center of the Second Hospital of Zhongshan, said that oral ulcers are also classified, and the most common is recurrent oral ulcers. During the attack, the mucous membrane in the mouth is necrotic, forming ulceration. The bigger the ulceration point, the more painful it is, but it is self-limited, and it can recover naturally in about 7~ 10 days. Ulcer will appear in any part of mucous membrane, generally in places where buccal mucosa, tongue and lips often exercise, so the pain is very obvious during the attack, and recurrence will have a great impact on the work and life of patients.
Oral ulcers occur all year round, but patients are especially common in summer. From the perspective of traditional Chinese medicine, emotion, sleep and poor diet are all inducing factors of oral ulcer. When the weather is hot in summer, people are easily agitated and excited, and then their appetite is bad and their sleep is easily disturbed. They can't sleep and don't wake up easily. These physical obstacles are easy to cause oral ulcers, so oral ulcers are concentrated every summer.
Patient A Kang was only 26 years old and was diagnosed with tongue cancer. The earliest warning signal was oral ulcer. Three weeks ago, A Kang had an oral ulcer, and his family said that he was getting angry, so he went to see a Chinese doctor, but he didn't get well after several visits. The doctor reminded him to do further examination, and he found early tongue cancer as soon as he did.
Experts remind that many people have an illusion that oral ulcers are inflammatory lesions, and it doesn't matter whether they go to the hospital or not. Take some anti-inflammatory drugs and you'll be fine. However, among many oral ulcers, a few are not recurrent oral ulcers, including tuberculous ulcers and syphilitic ulcers, and will not heal themselves. Even some oral ulcers are the early manifestations of some malignant tumors, such as tongue cancer, gingival cancer's disease and buccal mucosa cancer. If you turn a blind eye to this kind of ulcer, or treat it as inflammation with your own "experience", it will inevitably delay the disease, accelerate the spread, and the consequences will be unimaginable.
Ulcer is easy to become cancerous if it exists for a long time.
In fact, it is easy to distinguish between recurrent ulcers and oral ulcers caused by tumors. The former is round, soft to the touch, recurrent, usually cured in a week or so. The latter is irregular in shape, and lumps can be felt around and at the bottom of the ulcer. The pain is not obvious at the beginning, but it develops very rapidly and cannot be cured for a long time.
In addition, chronic ulcers in the mouth may become cancerous due to frequent stimulation of chewing and speaking. That is, those parts in contact with teeth, because patients are unwilling to pull out the remaining broken teeth, or improper denture making, constantly stimulate sharp edges and scrape mucous membranes, resulting in ulcers. If the stimulating factors are not removed, the ulcer will not heal, but will only get worse. This long-lasting ulcer is a precancerous lesion, which is very easy to become cancerous.
