Lip paresthesia during mandibular molar orthodontic distalization is rare. When it occurs, it is often related to excessive dimensions of the mandibular second molar roots. In this clinical report, we describe a patient who developed lip paresthesia during orthodontic treatment. The paresthesia was relieved by immediate interruption of the forces applied to the mandibular second molars and pharmacologic therapy. Before fixed orthodontic treatment proceeds in patients with large tooth roots, it is important to diagnose the relationship between the roots and the mandibular canal to prevent nerve numbness and damage.
下颌磨牙正畸远移过程中出现唇部感觉异常较为罕见。当这种情况发生时，通常与下颌第二磨牙牙根尺寸过大有关。在本临床报告中，我们描述了一名在正畸治疗期间出现唇部感觉异常的患者。通过立即中断施加于下颌第二磨牙的力并进行药物治疗，感觉异常得到缓解。在对牙根较大的患者进行固定正畸治疗之前，诊断牙根与下颌管之间的关系以预防神经麻木和损伤非常重要。
