Abstract

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.

[x线与CBCT三维重建对青少年埋伏牙正畸患者的诊断价值分析]。

目的：探讨x线与锥束CT（CBCT）三维重建对青少年正畸患者阻生牙的诊断价值。方法：选择2021年5月~ 2024年5月在保定市第二医院住院的青少年正畸患者86例126颗阻生牙进行x线检查和CBCT三维重建。通过比较两种方法对阻生牙位置和邻近解剖结构的显示能力，评价两种方法的诊断效率和准确性。采用SPSS 26.0软件包对数据进行统计分析。结果：126例阻生牙中，上颌前牙区40例（52颗牙），上颌后牙区8例（12颗牙），上颌多生牙12例（20颗牙），下颌前牙区14例（22颗牙），下颌后牙区8例（14颗牙），下颌多生牙4例（6颗牙）。CBCT三维重建结果与手术表现接近。CBCT三维重建在大多数指标上都优于x线片，特别是在敏感性和阳性预测值方面，显示出更高的诊断效率。结论：CBCT三维重建对青少年正畸患者阻生牙的诊断具有较高的诊断价值，尤其是对阻生牙位置的准确评估。
