This report presents a case of external cervical resorption and illustrates the effects of a non-surgical approach in the amelioration of this condition and discusses the etiology, classifications, and treatment options.
One of the most common root resorption forms is external cervical resorption, which initiates in the cervical area of the tooth and spreads out in the thickness of the dentin in an irregular way. This resorptive process may spread across the dentin leading to significant loss of tooth structure, with or without pulp involvement.
During a routine radiographic examination of a 25-year-old female patient, external cervical resorption in a maxillary right second premolar was discovered. Cone-beam computed tomography (CBCT) confirmed the extension of the lesion into the pulp and the need for root canal treatment. The defect was sealed with bioceramic putty. One year CBCT follow-up demonstrated the cessation of the resorption site with no clinical symptoms.
CBCT examination and combining non-surgical root canal treatment with non-surgical repair using bioceramic putty was an effective treatment option.
Treatment selection of external cervical resorption depends on many factors, including the location and severity of the resorptive defect and the remaining tooth structure. If the resorptive defect has extended to the pulp, the management involves root canal treatment and subsequent placement of a direct restoration to restore the resorptive lesion.
本报告介绍了一例外吸收，并说明了非手术方法在改善这种情况中的作用，并讨论了病因、分类和治疗选择。
最常见的根吸收形式之一是外吸收，它起始于牙齿的颈部区域，并以不规则的方式在牙本质的厚度中扩散。这个吸收过程可能会扩散到牙本质，导致牙齿结构的显著丧失，无论是否涉及牙髓。
在对一名 25 岁女性患者进行常规放射检查时，发现上颌右侧第二前磨牙有外吸收。锥形束计算机断层扫描（CBCT）证实病变延伸到牙髓，需要根管治疗。用生物陶瓷腻子封闭缺损。一年后的 CBCT 随访显示，吸收部位停止，无临床症状。
CBCT 检查和联合非手术根管治疗与生物陶瓷腻子的非手术修复是一种有效的治疗选择。
外吸收的治疗选择取决于许多因素，包括吸收缺陷的位置和严重程度以及剩余的牙齿结构。如果吸收缺陷已经延伸到牙髓，治疗方法包括根管治疗和随后放置直接修复体以修复吸收病变。
