■这项研究的目的是对硅岩的超微结构和化学成分进行比较分析,扁桃体,并描述它们的生长模式。
■我们从18名患者中获得了19个标本,并将标本分为三组:唾液石(A),扁桃体(B),和antrolith(C)。外围,中间,通过组织学对标本的核心区域进行了详细检查,微型计算机断层扫描(micro-CT),扫描电子显微镜(SEM),能量色散X射线光谱,和透射电子显微镜(TEM)。
■在微CT中,A组显示交替的放射致密层和放射透层,B组结构均匀。C组标本显示出紧密均匀的结构。组织病理学,A组表现为层压,泪滴形,球状结构。B组显示有机和无机材料的未成熟钙化程度。C组,病变未被包裹,并显示出均匀的板层骨结构。SEM显示,A组显示出不同的三层:外围多层区,中间紧凑区,和中央病灶区;B组和C组未显示这些层。硅岩的主要元素成分为O,C,Ca,N,Cu,P,Zn,Si,Zr,F,Na,Mg。B组,在外围区域发现了少量的铁。C组的成分列表较短:Ca,C,O,P,F,N,Si,Na,Mg。A组的TEM分析显示球形结构发生囊内钙化。B组,细菌存在于中间层。在C组的外层,观察到成骨细胞结缘。
■Sialoliths具有不同的三层:外围多层区,中间紧凑区域和中央nidus区域,而扁桃体和针石标本缺乏不同的层和核心。
UNASSIGNED: The aim of this study was to perform a comparative analysis of the ultrastructural and chemical composition of sialoliths, tonsilloliths, and antroliths and to describe their growth pattern.
UNASSIGNED: We obtained 19 specimens from 18 patients and classified the specimens into three groups: sialolith (A), tonsillolith (B), and antrolith (C). The peripheral, middle, and core regions of the specimens were examined in detail by histology, micro-computed tomography (micro- CT), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, and transmission electron microscopy (TEM).
UNASSIGNED: In the micro-CT, group A showed alternating radiodense and radiolucent layers, while group B had a homogeneous structure. Group C specimens revealed a compact homogeneous structure. Histopathologically, group A showed a laminated, teardrop-shaped, globular structure. Group B demonstrated degrees of immature calcification of organic and inorganic materials. In group C, the lesion was not encapsulated and showed a homogeneous lamellar bone structure. SEM revealed that group A showed distinct three layers: a peripheral multilayer zone, intermediate compact zone, and the central nidus area; groups B and C did not show these layers. The main elemental components of sialoliths were O, C, Ca, N, Cu, P, Zn, Si, Zr, F, Na, and Mg. In group B, a small amount of Fe was found in the peripheral region. Group C had a shorter component list: Ca, C, O, P, F, N, Si, Na, and Mg. TEM analysis of group A showed globular structures undergoing intra-vesicular calcification. In group B, bacteria were present in the middle layer. In the outer layer of the group C antrolith, an osteoblastic rimming was observed.
UNASSIGNED: Sialoliths had distinct three layers: a peripheral multilayer zone, an intermediate compact zone and the central nidus area, while the tonsillolith and antrolith specimens lacked distinct layers and a core.
