Stability and prognosis of teeth with severe root resorption is problematic in orthodontics. Because severe root resorption, when it occurs in orthodontic patients, is an iatrogenic consequence of treatment, periodic analysis for all patients is encouraged. This article reports a case of severe root resorption 25 years after the completion of orthodontic treatment. The root resorption did not exhibit significant progression and the patient had a healthy periodontal status. Orthodontic patients with sharp, pointed roots who require premolar extraction might have a greater risk of severe root resorption.
正畸治疗中，严重的牙根吸收会影响牙齿的稳定性和预后。因为严重的牙根吸收是正畸治疗的医源性后果，所以建议所有患者定期进行分析。本文报告了正畸治疗完成 25 年后发生严重牙根吸收的病例。该患者的牙根吸收没有明显进展，牙周状况健康。需要拔除前磨牙的牙根尖锐、呈锐角的正畸患者，可能有更大的发生严重牙根吸收的风险。
