摘　　要：目的:探讨上颌中高位近中水平或垂直阻生智齿与相邻上颌第二磨牙牙根外吸收(ERR)之间的关系。方法:收集2019~2022年就诊的88例患者共计93颗患牙的临床资料,对上颌中高位近中水平或垂直阻生第三磨牙引起相邻第二磨牙ERR的相关因素进行分析。结果:上颌第二磨牙ERR的患病率为44.1%,性别和年龄不同,上颌第三磨牙阻生方向不同,第二磨牙ERR发生率差异无统计学意义(P>0.05);上颌智齿阻生深度不同第二磨牙ERR发生率差异有统计学意义(P<0.05)。结论:上颌第三磨牙高位阻生更易导致相邻第二磨牙ERR的发生,建议临床上尽早预防性拔除。Objective:To investigate the relationship between maxillary mid-high proximal-mid,horizontal,or vertical impacted third molars and external root resorption(ERR)of adjacent maxillary second molars.Methods:Clinical data were collected from 88 patients with a total of 93 affected teeth visited from 2019 to 2022,and the factors associated with the ERR of adjacent second molar caused by a maxillary mid-high proximal-mid,horizontal,or vertical impacted third molar were analyzed.Results:The prevalence of maxillary second molar ERR was 44.1%,and there was no statistically significant difference in the gender,age,and direction of maxillary third molar obstruction(P>0.05).However,there was a statistically significant difference in the depth of maxillary wisdom teeth obstruction(P<0.05).Conclusion:High maxillary third molar obstruction is more likely to cause second molar ERR,and early prophylactic extraction is recommended in clinical practice.
