The calcified structures that form within the parenchymal tissues or the canal of the salivatory glands are called salivatory stones or sialolithiasis. They contain calcium phosphate, 74.3%; calcium carbonate 11.1%; soluble salt, 6.2%; organic elements, 2.2% and water. The stones are formed by the precipitation of calcified structures around a nucleus that is made of the foreign bodies in the gland, desquamated epithelial cells, degradation products of the bacteria or the bacteria itself. 83% of the salivatory stones is found in the submandibular gland, 10% of them belongs to the parotid and the sublingual gland comes up with 7%. Aside from the major salivatory glands, the minor ones also contain stones. The stones can be classified as anterior, posterior and intraglandular according to the position. The unilateral stones, usually, when reached to the considerable size, cause to partial or total obstruction of the canals. We examined the two cases that have stones localized within the canals of submandibular gland when we were unable to use the sialography technique because of the obstruction the ultrasoundography was our other choice we had direct measurements of the stones and the gland both. After the operation a chemical analysis showed that the stones include calcium and magnesium as cations and phosphate and carbonate as anions.
在唾液腺实质组织或导管内形成的钙化结构称为唾液腺结石或涎石病。它们含有74.3%的磷酸钙、11.1%的碳酸钙、6.2%的可溶性盐、2.2%的有机成分和水。结石是由围绕腺体内异物、脱落的上皮细胞、细菌降解产物或细菌本身形成的核心周围钙化结构沉淀而成。83%的唾液腺结石位于下颌下腺，10%位于腮腺，7%位于舌下腺。除了主要的唾液腺外，小唾液腺也会有结石。根据位置，结石可分为前部、后部和腺内结石。单侧结石通常在达到相当大的尺寸时，会导致导管部分或完全阻塞。我们检查了两例结石位于下颌下腺导管内的病例，当时由于阻塞无法使用涎管造影技术，超声检查是我们的另一种选择，我们对结石和腺体都进行了直接测量。手术后的化学分析表明，结石中的阳离子包括钙和镁，阴离子包括磷酸盐和碳酸盐。
