摘　　要：目的:评估X线与锥形束CT(CBCT)三维重建对青少年正畸患者埋伏牙诊断的价值。方法:选择2021年5月—2024年5月保定市第二医院收治的86例青少年正畸患者,共126颗埋伏牙,进行X线检查和CBCT三维重建。比较2种方法在显示埋伏牙位置及邻近解剖结构的能力,评估其诊断效率和准确性。采用SPSS 26.0软件包对数据进行统计学分析。结果:126颗埋伏牙中,上颌前牙区40例(52颗),上颌后牙区8例(12颗),上颌多生牙12例(20颗);下颌前牙区14例(22颗),下颌后牙区8例(14颗),下颌多生牙4例(6颗)。CBCT三维重建和手术结果较为接近。CBCT三维重建多数指标显著优于X线,特别是在敏感度和阳性预测值上,显示出更高的诊断效能。结论:CBCT三维重建在青少年正畸患者的埋伏牙诊断中诊断价值较高,尤其是在精确评估埋伏牙位置方面。PURPOSE:To evaluate the value of X-ray and cone-beam CT(CBCT)three-dimensional reconstruction in the diagnosis of impacted teeth in adolescent orthodontic patients.METHODS:From May 2021 to May 2024,totally 86 adolescent orthodontic patients with 126 impacted teeth admitted to the Second Hospital of Baoding City were selected for X-ray examination and CBCT 3D reconstruction.The diagnostic efficiency and accuracy of the two methods were evaluated by comparing their ability to reveal the location and adjacent anatomical structures of the impacted teeth.SPSS 26.0 software package was used for statistical analysis of the data.RESULTS:Among the 126 impacted teeth,totally 40 cases(52 teeth)were in the maxillary anterior tooth region,8 in the maxillary posterior region(12 teeth),12 with maxillary supernumerary teeth(20 teeth),14 in the mandibular anterior region(22 teeth),8 in the mandibular posterior region(14 teeth),and 4 with mandibular supernumerary teeth(6 teeth).The results of CBCT 3D reconstruction were close to operation findings.CBCT 3D reconstruction was superior to X-ray films in most indexes,especially in sensitivity and positive predictive value,showing higher diagnostic efficiency.CONCLUSIONS:CBCT three-dimensional reconstruction provides high diagnostic value in the diagnosis of impacted teeth in adolescent orthodontic patients,especially in accurately assessing the position of impacted teeth.
