目的作为放射组学定量分析的一部分，本研究旨在利用正畸前计算机体层摄影(CT)纹理分析对上颌中切牙牙根进行定量评估。方法采用回顾性病例对照研究方法，对16例有根尖外根吸收(EARR)的患者和16例年龄、性别匹配的无EARR的患者进行正畸治疗后进行颌骨畸形的正畸前CT检查。所有患者在手术正畸治疗前后均使用固定正畸矫治器治疗。EARR定义为正畸治疗2年后左右上颌中切牙在CT图像上的牙根吸收大于等于2 mm。应用开放获取软件Mazda Ver分析正畸治疗前后上颌中切牙EARR的纹理特征。3.3.用马自达的Fisher方法从279个原始参数中选择了10个纹理特征，这些参数分别计算了有无EARR的上颌中切牙。结果用学生t检验、韦尔奇t检验或曼恩-惠特尼U检验进行检验。结果4个灰度游程矩阵特征和6个灰度共生矩阵特征在两组间有显著差异(p<；0.01)。结论CT纹理分析能定量评价上颌中切牙牙根，并能区分上颌中切牙牙根有无EARR。CT纹理分析可能是预测正畸治疗后EARR的有用方法。
Objectives This study aimed to quantitatively assess maxillary central incisor roots using pre-orthodontics computed tomography (CT) texture analysis as part of a radiomics quantitative analysis. Methods This retrospective case-control study included 16 patients with external apical root resorption (EARR) and 16 age- and sex-matched patients without EARR, after orthodontic treatment who underwent pre-orthodontics CT for jaw deformities. All patients were treated with a fixed orthodontic appliance before and after surgical orthodontic treatment. EARR was defined as root resorption >= 2 mm of the left and right maxillary central incisors on CT images more than 2 years after the start of orthodontic treatment. Texture features of the maxillary central incisor with and without EARR after orthodontic treatment were analyzed using the open-access software, MaZda Ver. 3.3. Ten texture features were selected using the Fisher method in MaZda from 279 original parameters, which were calculated for each of the maxillary central incisors with and without EARR. The results were tested using the Student's t test, Welch's t test, or Mann-Whitney U test. Results Four gray-level run length matrix features and six gray-level co-occurrence matrix features displayed significant differences between both the groups (p < 0.01). Conclusions CT texture analysis was able to quantitatively assess maxillary central incisor roots and distinguish between maxillary central incisor roots with and without EARR. CT texture analysis may be a useful method for predicting EARR after orthodontic treatment.
