目的：探讨锥形束CT（CBCT）在阻生牙所致邻牙牙根外吸收诊治中的应用价值。方法选择2011年1-12月广州军区武汉总医院口腔科诊治，经全口曲面体层片确定存在阻生牙，邻牙牙根外吸收情况不明确的患牙19颗（15例）。所有患者进行CBCT扫描和三维重建，确定牙根外吸收的部位及程度。结果经CBCT扫描和三维重建后，所有患者均直观显示牙根外吸收的部位及程度，以及阻生牙在颌骨中的三维位置及其与周围重要组织的关系。结论CBCT可直观、准确地显示牙根外吸收的部位和程度，对阻生牙所致邻牙牙根外吸收的诊断和治疗提供可靠信息。

Objective This study aims to investigate the diagnosis and treatment of external root resorption of adjacent teeth caused by impacted teeth via cone-beam computed tomography (CBCT). Methods A total of 19 teeth from 15 patients with uncertain external root resorption caused by an adjacent impacted tooth were examined from January 2011 to December 2011. All teeth with uncertain external root resorption were scanned by CBCT. Three dimensions reconstruction were the con-ducted to determine the location and extent of resorption. Results In all cases, CBCT identified the accurate location and extent of external root resorption caused by adjacent impacted teeth. Furthermore, the technique provided impacted teeth location in three dimensions, including the relation between the impacted teeth and surrounding vital structures. Conclusion CBCT can provide direct and accurate images of the location and extent of external root resorption, as well as the location of the adja-cent impacted teeth in three dimensions. Therefore, the proposed technique provides reliable information for clinical diagnosis and treatment.
