The purposes of this study were to evaluate the location, nature, and occurrence of incidental findings in maxillofacial structures on 3-dimensional cone-beam volumetric scans done for dental diagnostic purposes and to look for associations between these findings and symptoms in orthodontic patients.
Images from 500 consecutive maxillofacial 3-dimensional scans were examined. The patient sample consisted of 252 orthodontic patients, 172 implant patients, 33 endodontic patients, 34 temporomandibular joint (TMJ) disorder patients, and 10 others.
The overall rate of incidental findings was 24.6% (123 patients of 500). The highest rate of incidental findings was in the airway area (18.2%), followed by TMJ findings (3.4%), endodontic findings (1.8%), and others (1.2%). In the orthodontic group, the incidences were airway findings, 21.4%; TMJ findings, 5.6%; and endodontic lesions, 2.3%. Only 22% of the airway findings, such as mucosal thickness, polyps, and retention cysts, were correlated with clinical signs and symptoms.
For clinical diagnosis, the data should be interpreted with a full history of clinical signs and symptoms, and with detailed communications with radiological colleagues and other specialists to comprehensively evaluate possible underlying diseases.
本研究的目的是评估在为牙科诊断目的而进行的三维锥形束容积扫描中，颌面部结构偶然发现的位置、性质和发生率，并寻找这些发现与正畸患者症状之间的关联。
检查了连续500例颌面部三维扫描的图像。患者样本包括252例正畸患者、172例种植牙患者、33例牙髓病患者、34例颞下颌关节（TMJ）紊乱患者和10例其他患者。
偶然发现的总体发生率为24.6%（500例患者中的123例）。偶然发现发生率最高的是气道区域（18.2%），其次是颞下颌关节发现（3.4%）、牙髓病发现（1.8%）和其他（1.2%）。在正畸组中，发生率分别为气道发现21.4%、颞下颌关节发现5.6%和牙髓病病变2.3%。只有22%的气道发现，如黏膜厚度、息肉和潴留囊肿，与临床体征和症状相关。
对于临床诊断，应结合完整的临床体征和症状病史，并与放射科同事及其他专家进行详细沟通，以全面评估可能的潜在疾病，从而解读数据。
