The purpose of this study was to undertake a three-dimensional analysis of the vascular network of the lamina propria in the gingiva, alveolar mucosa, buccal mucosa, palate, and lingual mucosa of the dog. Using the corrosive resin casting technique, casts of the vascular network were prepared and examined by scanning electron microscopy. In the oral mucosa, larger arteries in the submucosa divide into smaller branches that enter the lamina propria. These branches form one or more layers of vessels at the base of the papillae of the lamina propria, the so-called subpapillary vascular network. Here the vessels divide again and enter the papillae to form a subepithelial capillary network. The configuration of the capillary loops within each papilla of the lamina propria is determined by the shape of the papilla. The characteristic shape of the loops resembles a hairpin. The capillary loops in the lingual papillae are larger and more complex than capillary loops found elsewhere in the oral mucosa. The mucosa of the posterior portion of the hard palate, the soft palate, and the tongue contain many venous valves.
本研究的目的是对犬牙龈、牙槽黏膜、颊黏膜、腭和舌黏膜固有层的血管网络进行三维分析。采用腐蚀树脂铸型技术制备血管网络铸型，并通过扫描电子显微镜进行观察。在口腔黏膜中，黏膜下层的较大动脉分支形成较小的分支进入固有层。这些分支在固有层乳头基部形成一层或多层血管，即所谓的乳头下血管网。在这里，血管再次分支并进入乳头形成上皮下毛细血管网。固有层每个乳头内毛细血管袢的形态由乳头形状决定。这些袢的特征形状类似发夹。舌乳头中的毛细血管袢比口腔黏膜其他部位的毛细血管袢更大、更复杂。硬腭后部、软腭和舌的黏膜含有许多静脉瓣。
