Orthodontic treatment in patient with idiopathic root resorption: A case report

Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors. If an etiological factor cannot be identified for root resorption, the term "idiopathic" is applied. This report presents a case of multiple idiopathic apical root resorption. The condition was found in a young female patient seeking orthodontic treatment due to malocclusion. This kind of resorption starts apically and progresses coronally, causing a gradual shortening and rounding of the remaining root. Patients with this condition are not the ideal candidates for orthodontic treatment; however, the aim of this report is to describe an unusual case of idiopathic root resorption involving the entire dentition, and to present the orthodontic treatment of this patient. It describes the progress and completion of orthodontic therapy with satisfactory end results.

多发性特发性外牙根吸收（multiple idiopathic external root resorption）是一种罕见的病理状态，通常在影像学检查中作为偶然发现被检出。恒牙外牙根吸收是一种多因素致病过程，与多种局部及全身因素相关。若无法明确牙根吸收的病因，则将该病症定义为“特发性”牙根吸收。本报告报道1例多发性特发性根尖牙根吸收病例。该病例的患者为一名因错𬌗畸形寻求正畸治疗的年轻女性。此类牙根吸收始发于根尖区域，并向冠方进展，致使剩余牙根逐渐缩短并呈圆钝形态。此类患者并非正畸治疗的理想适应证人群；然而，本报告旨在描述1例累及全牙列的罕见特发性牙根吸收病例，并介绍该患者的正畸治疗过程，详述正畸治疗的实施进程与最终完成情况，最终取得了满意的治疗效果。
