摘要/Abstract

摘要： 目的: 通过分析上切牙区单颗埋伏多生牙患者的锥形束CT(cone-beam computed tomography,CBCT)特点,探讨对邻近结构产生影响的危险因素。方法: 对182例上切牙区单颗埋伏多生牙患者的CBCT资料进行分析,从多生牙形态、方向、位置、牙根发育以及对邻近结构影响等特征进行统计,采用χ²检验及Logistic回归分析进行统计学分析。结果: 多生牙是否对邻近结构产生影响与患者年龄、多生牙水平向位置、邻牙牙根发育情况有关(P＜0.05);与患者性别、多生牙形态、方向、垂直向位置、矢状向位置、多生牙牙根发育情况无关(P＞0.05)。且多生牙水平向位置位于11-21相对于位于12-11、21-22更容易影响邻近结构(P＜0.05,OR=0.342、0.387);邻牙牙根发育至7、8期时相对于邻牙牙根发育完全,多生牙更容易产生重度影响(P＜0.05,OR=0.027、0.525)。结论: 上切牙区单颗埋伏多生牙水平向位置位于11-21间时,以及邻牙牙根发育至7、8期时,应尽早拔除多生牙,避免其影响邻近结构。

Abstract: Objective: To explore the risk factors that may affect adjacent structures by analyzing the characteristics of cone-beam computed tomography (CBCT) in patients with single impacted supernumerary teeth in the upper incisor area. Methods: CBCT was observed in 182 patients with single impacted supernumerary teeth in the upper incisor area, and statistical analysis was conducted on the morphology, direction, position, root development, and impact on adjacent structures of supernumerary teeth. Results: The impact of supernumerary teeth on adjacent structures was related to the patient's age, the horizontal position of supernumerary teeth, and the development of adjacent tooth roots (P<0.05). It was not related to the patient's gender, morphology, orientation, vertical position, sagittal position, or root development of supernumerary teeth (P>0.05). Moreover, the horizontal position of supernumerary teeth located between 11-21 was more likely to affect adjacent structures compared to those located between 12-11 and 21-22 (P<0.05, OR=0.342/0.387). When the root development of adjacent teeth reached stages 7 and 8, compared to when the root development of adjacent teeth was complete, supernumerary teeth were more likely to have severe effects (P<0.05, OR=0.027/0.525). Conclusion: When single impacted supernumerary tooth is located horizontally between 11-21 in the upper incisor area, and when the root of adjacent teeth develops to stage 7 or 8, supernumerary teeth should be removed as early as possible to prevent them from affecting adjacent structures.
