Third lower molar partially erupted is commonly encountered in dental practice. This situation challenges clinicians with the dilemma whether to remove or to monitor it, because this molar can cause pathology of the adjacent second molar. The aim of this retrospective study is to evaluate the relationship between third mandibular molar and distal cervical caries in second molar. This retrospective study analyzed 55 digital orthopantograms of adult patients and a total number of 95 mandibular third molars were assessed for eruption status, angulation, radiographic evidence of caries or restoration in the mandibular third molar, and radiographic evidence of caries or restoration in the distal surface of the mandibular second molar. The distal cervical caries in second molar is associated with fully erupted and partially erupted wisdom molar in horizontal, mesioangular and vertical position and less with presence of caries in third molar. There are caries lesions in distal second molars in mesioangular position when adjacent third molar is caries free.
下颌第三磨牙部分萌出在牙科临床实践中较为常见。这种情况使临床医生面临两难抉择，即是否拔除或观察该磨牙，因为它可能导致相邻第二磨牙出现病变。本回顾性研究的目的是评估下颌第三磨牙与第二磨牙远中颈部龋之间的关系。这项回顾性研究分析了55例成年患者的数字化曲面断层片，共评估了95颗下颌第三磨牙的萌出状态、倾斜角度、下颌第三磨牙的龋坏或修复的影像学证据，以及下颌第二磨牙远中面的龋坏或修复的影像学证据。第二磨牙远中颈部龋与水平、近中倾斜和垂直位置的完全萌出及部分萌出的智齿有关，与第三磨牙龋坏的关系较小。当相邻第三磨牙无龋时，近中倾斜位置的第二磨牙远中面会出现龋损。
