摘要：

下颌后牙区尤其是下颌第一磨牙根尖到下颌神经管上缘的距离多数仅为1 ~ 4 mm。因此，当下颌后牙区罹患重度牙周炎和（或）根尖周炎时，炎症有可能扩散累及邻近的下颌神经管，引起相应区域的神经感觉异常。此类病例罕见，病情复杂，相应的治疗往往需要多学科医生参与共同完成。笔者根据自己的临床体会结合文献报道就其病因机制及多学科治疗策略做一梳理。

Abstract:

Mostly，the distance between mandibular canal and apices of molars，especially the mandibular first molar，varies only between 1 mm and 4 mm. Thus，mandibular canal can be compromised due to the expanding infection which originates from severe periodontitis and/or perioapical periodontitis in mandibular molar region，characterized by a neurosensitivity disturbance in its innervated area. This kind of cases are rare and complicated，and the treatment often requires the participation of multidisciplinary doctors. Combined with the literature review，we  summerized their etiopathogenic mechanisms and multidisciplinary treatment strategy.
