We processed 28 samples of human gingiva in health or paradential illness, of 15 patients between 20 to 67 years old. In 306 histologies cuts we made different staining to light microscope. We analyzed presence, distribution, diameter and relations of the elastic, elaunin and oxytalan fibers. The patron of distribution fibrilar of the elastic system gingival was different than other zones of the body. The description had made in three zones of the gingival connective tissue: deep, subpapilar and papilar zones. The elastic fibers had less numerous and larger diameter than the elaunin y oxytalan ones. Their repair was irregular. The elaunin followed the colagen fibers. The oxytalan formed delicates nets in the lodge of connective tissue, inflamatories infiltrates and interfibrilar spaces. They came to the basal membrane perpendicularly or oblicualy, isolated or in little bundles. The fibers of elastic system increased principaly in inflamed gingiva of teeth with overburden, though they supported the low proportion that exist at health gingiva. They appeared at the little vases wall and were increased at zones next to edentate spaces. The analogy and close entail between the elaunin and oxytalan fibers to colagen ones, made think in a relation of reenforcement of colagen, increased at paradential illness.
我们对15名年龄在20至67岁之间的患者的28份健康或牙周疾病状态下的人牙龈样本进行了处理。在306个组织切片中，我们对光镜进行了不同的染色。我们分析了弹性纤维、弹力纤维和氧化弹力纤维的存在、分布、直径及相互关系。牙龈弹性系统的纤维分布模式与身体其他部位不同。描述是在牙龈结缔组织的三个区域进行的：深层、乳头下区域和乳头区域。弹性纤维比弹力纤维和氧化弹力纤维数量更少且直径更大。它们的修复不规则。弹力纤维沿着胶原纤维分布。氧化弹力纤维在结缔组织、炎性浸润和纤维间间隙中形成精细的网络。它们垂直或倾斜地到达基底膜，单独或成小束状。弹性系统的纤维主要在有咬合负担的牙齿的发炎牙龈中增加，尽管它们在健康牙龈中的比例较低。它们出现在小血管壁上，并在无牙间隙附近的区域增加。弹力纤维和氧化弹力纤维与胶原纤维之间的相似性和紧密联系，使人想到在牙周疾病时胶原增强的关系。
