摘要:
目的 分析锥形束CT(CBCT)联合全景片在下颌骨阻生牙拔除术前检查的临床价值。 方法 选取2019年1月~2020年1月于本院就诊的102例下颌骨阻生牙拔除患者(126颗下颌骨阻生牙)为研究对象。所有患者在术前均接受口腔影像学检查,记录阻生牙相关变量:牙根成角、牙根数、牙根远端和近中根形态、与下颌神经管的关系,在术中和术后评估以上变量以作为金标准。 结果 全景片图像无法清晰显示牙根与下牙槽神经管三维关系,CBCT图像中显示清晰;全景片、CBCT及CBCT联合全景片在评估成角、牙根数、远中根的弯曲情况、远中根向近中或远中弯曲、近中根弯曲、近中根近中或向远中弯曲中的差异无统计学意义(P>0.05);三者评估牙根与下颌管关系的差异有统计学意义(P < 0.05);患者拔牙时间为15.93±3.24 min,出血量为26.45± 3.15 mL,仅有1颗(0.79%)出现断根;术中仅有1例患者出现断根、根折,1例出现舌侧骨板骨折;术后无出血、感染患者,有2例患者出现感觉麻木、1例患者出现肿胀和受限。 结论 CBCT联合全景片在确定下颌第三磨牙与下颌管之间的关系方面有较大的优势,对改善患者术中情况和术中及术后并发症有积极意义。 Abstract:Objective To analyze the clinical value of cone- beam CT (CBCT) combined with panoramic radiography in the preoperative examination of impacted mandibular teeth extraction. Methods A total of 102 patients with mandibular impacted teeth (126 impacted teeth) treated in our hospital from January 2019 to January 2020 were selected. All patients underwent preoperative oral imaging, and the related variables of impacted teeth, including root angulation, root number, distal and mesial root morphology, and relationship with mandibular neural tube were recorded. and the above variables were evaluated as gold standard intraoperatively and postoperatively. Results The panoramic images could not clearly show the threedimensional relationship between the root and the inferior alveolar neural tube, which was clearly shown in the CBCT images. There were no significant differences in angle formation, root number, distal root bending, proximal root bending or distal root bending, proximal root bending or proximal root bending (P>0.05) in panoramic image, CBCT and CBCT combined panoramic image. There were statistically significant differences in the relationship between root and mandibular canal (P < 0.05). The extraction time was 15.93±3.24 min, the bleeding volume was 26.45±3.15 mL, only one (0.79%) had root breakage. During the operation, only one patient developed root breakage and root fracture, and one patient developed lingual bone plate fracture. there were no patients with bleeding or infection postoperatively, and two patients showed numbness and one showed swelling and limitation. Conclusion CBCT combined with panoramic radiography has great advantages in determining the relationship between the mandibular third molars and the mandibular canal, which has positive significance in improving intraoperative situation and intraoperative and postoperative complications of patients. -
