Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unless pulpal or periodontal infection supervenes. Radiographic features of lesions vary from well-delineated to irregularly bordered mottled radiolucencies, and these can be confused with dental caries. A characteristic radiopaque line generally separates the image of the lesion from that of the root canal, because the pulp remains protected by a thin layer of predentin until late in the process. Histopathologically, the lesions contain fibrovascular tissue with resorbing clastic cells adjacent to the dentin surface. More advanced lesions display fibro-osseous characteristics with deposition of ectopic bonelike calcifications both within the resorbing tissue and directly on the dentin surface.

侵袭性颈部吸收是一种相对罕见的外部牙根吸收形式,无外部体征。这种吸收情况常通过常规影像学检查发现。其临床特征各异,从牙龈边缘的小缺损到牙冠粉红色变色,最终导致覆盖的牙釉质出现空洞,除非继发牙髓或牙周感染,一般无痛。病变的影像学特征从边界清晰到边界不规则的斑驳透射影像不等,这些可能与龋齿混淆。一条特征性的阻射线通常将病变影像与根管影像分开,因为在病变后期之前牙髓一直受到一层薄的前期牙本质保护。组织病理学上,病变包含纤维血管组织,在牙本质表面有吸收性破骨细胞。更 advanced lesions display fibro-osseous characteristics with deposition of ectopic bonelike calcifications both within the resorbing tissue and directly on the dentin surface. 如何引用本文:Kandalgaonkar SD, Gharat LA, Tupsakhare SD, Gabhane MH. 侵袭性颈部吸收:综述。《国际口腔健康杂志》2013;5(6):124 - 30 。
