Disease Overview Gingival tumors originate from the periodontal membrane and connective tissue of the alveolar process of the jawbone, and do not have the unique structure of tumors, so they are not true tumors; however, gingival tumors have the appearance and biological behavior of tumors. 1.Etiology Gingival tumor is a proliferation formed by mechanical stimulation and chronic inflammatory stimulation, and it is also related to endocrine, for example, gingival tumor easily occurs during pregnancy in women, and after delivery, gingival tumor shrinks or stops growing. Gingival tumors can be divided into granuloma, fibrous and vascular types according to the different histological structures. Granuloma gingival tumor is mainly composed of granulation tissue, with red or pink surface and easy to bleed; fibrous gingival tumor contains more fibrous tissue and fibroblast, with smooth surface and color not much different from normal gum color, not easy to bleed; vascular gingival tumor contains more blood vessels and easy to bleed, such as gingival tumor of pregnancy. 2, clinical manifestations Gingival tumors are more common in women, and more often in young people and middle-aged people. Gingival tumors mostly occur in the gingival papillae of the lip and cheek, and are most common in the bicuspid region. The masses are confined, vary in size, round or oval, and sometimes lobulated. The masses are either tipped like polyps or non-tipped with a broad base. The masses generally grow slowly, but can increase rapidly in women during pregnancy. The mass can grow to cover part of the tooth surface and alveolar process, and the tooth indentation is visible on the surface, making it easy to be bitten and infected. When the mass grows, it can destroy the alveolar bone wall, resulting in loosening and displacement of the tooth. 3, diagnosis and differentiation (1) Most often seen in young adults, most often in the anterior region of the lip and buccal side of the gum. (2) Fibromatous gingival tumor: it is a true tumor, which starts from the gingival papilla and grows outward in a lobulated shape, with smooth surface, hard texture, grayish white, and not easy to bleed. Most of them are not large, but a few can increase in size to cover the biting surface of teeth, affecting mastication and developing traumatic ulcers. (3) Granuloma type service tumor: associated with local irritation such as gingival teeth, residual crowns, residual roots, bad dentures, calculus, etc. Inflammatory granulation tissue proliferation occurs in the gingiva, which is soft, red in color and bleeds easily. (4) Angiomatous gingival tumor: related to endocrine, commonly found in women during pregnancy, called gestational heel tumor, soft and easy to bleed. It develops quickly during pregnancy and can subside after delivery. (5) Gingival tumor should be differentiated from gingival cancer. (1) Surgical excision should include extraction of the alveolar process and affected teeth, otherwise it is prone to recurrence. (2) Removal of local irritants such as bad dentures, root remnants, crown remnants: etc. (3) Pregnancy gingival tumor can be surgically removed if it does not subside after delivery. 4, treatment (1) Surgical removal should include the extraction of the alveolar process and the affected teeth, otherwise it is easy to cause recurrence. (2) Remove local irritants such as bad dentures, root remnants, crown remnants: etc. (3) Pregnancy gingival tumors can be surgically removed if they do not subside after delivery.
