Internal resorption is a rare condition in permanent teeth, and may result from trauma, caries, or restorative procedures. Internal resorption is usually asymptomatic and is first identified as a round-shaped enlargement of a root-canal space on routine radiographs. Large resorption defects may result in penetration of the tooth into the periodontium through the cementum. The gold-standard treatment consists of debridement and obturation of the pulp space, sealing of the external communication, and restoration of the normal function of the tooth through a nonsurgical or surgical method. In this case presentation, we report on two methods for repair of internal resorption with perforation. The first method consisted of treating the lower right second premolar by conventional endodontic therapy under a microscope, followed by repair with mineral trioxide aggregate. The second method consisted of surgical treatment of the upper right central incisor. The choice of treatment depends on the size of the perforation, its location, and the ability to approach it for repair.
内吸收在恒牙中是一种罕见的情况，可能由外伤、龋齿或修复治疗引起。内吸收通常无症状，通常在常规X线片上首先被识别为根管腔呈圆形扩大。大的吸收缺损可能导致牙齿通过牙骨质穿入牙周组织。金标准治疗包括牙髓腔的清创和充填、外部通道的封闭，以及通过非手术或手术方法恢复牙齿的正常功能。在本病例报告中，我们报告了两种修复伴有穿孔的内吸收的方法。第一种方法包括在显微镜下对右下第二前磨牙进行常规根管治疗，然后用三氧化矿物凝聚体进行修复。第二种方法包括对右上中切牙进行手术治疗。治疗方法的选择取决于穿孔的大小、位置以及接近其进行修复的能力。
