There are two types of gum bleeding, one is bleeding when there is slight stimulation such as brushing, eating, sucking, etc. This kind of bleeding can mostly stop on its own and the bleeding volume is small. The other case is automatic bleeding without any stimulation, bleeding more, no self-limiting, the former is related to the situation factors; the latter is often caused by systemic factors. The causes of comprehensive gum bleeding are as follows: 1. Gingivitis and inflammatory hyperplasia: unclean gingivitis, interdental papillitis and inflammatory hyperplasia of the gums are common causes of gum bleeding. Often bleeding occurs when brushing, biting hard food, flossing or other stimuli, generally can stop on their own. Treatment: First of all, the cause should be removed, such as the cause of tartar stimulation, must be made for cleaning surgery, such as food embedding, then need to correct food embedding; such as bad restoration, should be removed. Secondly, give the necessary medication to control the infection. 2, periodontal disease: inflammatory periodontal disease patients gums are prone to bleeding, in addition, there are still periodontal pocket formation and overflow thick, alveolar bone resorption, tooth loosening and other symptoms, degenerative periodontal disease, although the general inflammation is not obvious, but some cases in the early stage has not yet appeared before the obvious periodontal pocket and alveolar bone attraction, that is, bleeding complaints, these patients often can not find obvious local irritation factors, only gingival edema, easy bleeding. Treatment can be done according to the principles of periodontal disease treatment. 3, necrotizing gingivitis: a mixed infection of Clostridium perfringens and oral spirochetes. The main manifestations are ulceration of interdental papillae, necrosis, putrefaction, pain and gingival bleeding. Treatment, the first change to improve oral hygiene, local use of 3% hydrogen peroxide solution with rinse, in addition to giving vitamin C, if necessary, antibiotics. 4, gingivitis and gestational tumor during pregnancy: during pregnancy, the gums are congested, edematous, and bleed easily when touched. After 3 – 4 months of pregnancy, gestational tumors tend to occur on the gingival papillae, tumor-like hyperplasia, easy to bleed when touched. Oral hygiene should be maintained. Pregnancy gingivitis can mostly heal on its own after delivery, and pregnancy tumors can shrink or stop growing after the pregnancy period, or gingival tumor removal can be performed after delivery. 5, liver disease: can reduce prothrombinogen or fibrinogen, resulting in poor blood clotting, when the oral cavity is damaged, persistent bleeding can occur. On examination, hepatomegaly, abnormal liver function, prolonged coagulation time and prothrombinogen time are seen. It can be treated with intramuscular injection of thrombin or heparin and injection of vitamin K. 6, thrombocytopenic purpura: in the oral mucosa or gum damage, can bleed more than; can also occur gum extensive automatic bleeding, in addition to the oral cavity, the skin and viscera can also appear petechiae, laboratory tests platelet count decreased, bleeding time is clearly prolonged, treatment can be used whole blood or platelet input, can use cortisone, or ACTH, etc. 7, leukemia: oral gum Jane now with dirt-like Swelling, ulceration, and can suddenly occur bleeding can be a small amount of long-term oozing. In addition, there is often general anemia, leukocytes and immature leukocytes, treatment, blood transfusions, cortisone, prednisone and other systemic treatment should be taken. 8, hemophilia: only seen in men, mostly in the extraction of teeth or oral minor injuries occur after the persistent oozing, often due to the lack of coagulation activator and prolonged blood clotting, treatment can be taken whole blood still twin bullying ninety plants rely on the piggyback Mei Fu centipede Fu? 9, aplastic anemia: can also Jane now for gum extensive bleeding. It is a group of syndromes caused by the obvious reduction of red bone marrow, hematopoietic function underneath, mainly manifested by the reduction of total white blood cells, often with anemia as the amount of first symptoms. Can take blood transfusion treatment 10, tumors: some tumors growing on the gums such as hemangioma, gingival tumors, etc., more likely to bleed, some tumors metastasized to the gums from the body actually parts, may also cause gum bleeding, such as choriocapillaris epithelial carcinoma. Treatment of the tumor should be started.
