We present the management of a case of Type II dens invaginatus in a mandibular premolar with a large invagination in the coronal third of the root on mesial aspect of the crown in proximity of cementoenamel junction significantly compromising the strength of the crown structure. We describe in detail the various measures taken to assess the internal tooth structure destruction and enhance the fracture resistance of the involved premolar. The case has a long-term follow-up of 36 months showing clinical and radiographic signs of healing. We highlight use of a simple "foil coated fiber postblocker technique" for root reinforcement in the first premolar. Successful management of teeth with dens invaginatus can be effectively done using with careful treatment planning and selection of reinforcing adhesive restorative materials.
我们介绍了一例下颌前磨牙II型牙内陷的治疗情况，该牙在牙冠近中面、靠近牙骨质牙釉质界处的牙根冠三分之一处有一个大的内陷，严重损害了牙冠结构的强度。我们详细描述了为评估患牙内部结构破坏情况以及增强患牙抗折性所采取的各种措施。该病例进行了36个月的长期随访，显示出临床和影像学上的愈合迹象。我们重点介绍了在第一前磨牙中使用简单的“箔涂层纤维桩阻挡技术”进行牙根加固。通过精心的治疗计划和选择增强型粘结修复材料，可以有效地成功治疗牙内陷的牙齿。
