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。

Abstract: 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.
