A complication of endodontic treatment is over-preparation of the tooth structure in an attempt to access calcified pulp chambers and root canals. This could result in thin root walls that might compromise the long-term prognosis of the tooth. There are various treatment options when such a complication occurs, among them, extraction of the compromised tooth and its replacement with a dental implant. This clinical report describes a nonsurgical, multidisciplinary treatment alternative where a maxillary anterior tooth with a thinned root wall was successfully saved by repairing the damaged root to its original thickness using a composite resin material and subsequently restoring with a cast post and core and a crown.
牙髓治疗的一个并发症是在试图进入钙化的牙髓腔和根管时过度预备牙齿结构。这可能导致牙根壁变薄，从而可能影响牙齿的长期预后。当出现这种并发症时，有多种治疗选择，其中包括拔除患牙并用牙种植体进行替代。本临床报告描述了一种非手术的多学科治疗方案，即通过使用复合树脂材料将受损牙根修复至原始厚度，随后用铸造桩核和冠进行修复，成功保留了上颌前牙牙根壁变薄的患牙。
