摘要:
目的 观察锥形束计算机体层摄影术（CBCT）检测口腔正畸中牙槽骨、牙根吸收状况的效果。方法 选择2016年1月~2017年7月我院进行口腔正畸治疗患者92例，均接受CBCT检测，比较治疗前、后中切牙牙槽骨厚度、牙根吸收情况。结果 治疗前后下颌、上颌根尖部、根中部、牙颈部牙槽骨厚度比较，差异无统计学意义（P＞0.05）；治疗后，下颌、上颌侧切牙牙根长度[（20.63±1.20）mm、（19.41±0.85）mm]、中切牙牙根长度[（21.12±1.19）mm、（21.74±1.02）mm]小于治疗前[（21.84±1.52）mm、（20.39±1.27）mm]、[（22.84±1.37）mm、（22.31±1.19）mm]，差异有统计学意义（P＜0.05）。结论 口腔正畸患者存在一定牙根吸收现象，但未见明显牙槽骨改建，CBCT检测可对口腔正畸患者牙根吸收进行评估，以期为临床预防牙根吸收提供确切信息。
Abstract:
Objective To observe the effect of cone beam computed tomography (CBCT) on the detection of alveolar bone and root resorption in orthodontics. Methods From January 2016 to July 2017, 92 patients with orthodontic treatment were enrolled in our hospital. All patients underwent CBCT. The alveolar bone thickness and root resorption of the incisors before and after treatment were compared. Results There were no significant differences in the thickness of the alveolar bone between the mandibular, maxillary root, central root and tooth before and after treatment (P>0.05). After treatment, the length of the mandibular and maxillary incisors was [20.63±1.20)mm, (19.41±0.85)mm], the length of the central incisor [21.12± 1.19)mm, (21.74±1.02)mm] is less than before treatment [(21.84±1.52)mm, (20.39±1.27)mm], [( 22.84±1.37)mm, (22.31±1.19)mm], the difference was statistically significant (P<0.05). Conclusion There is a certain root resorption in orthodontic patients, but no obvious alveolar bone remodeling. CBCT can evaluate the root resorption of orthodontic patients, which is helpful to provide accurate information for clinical prevention of root resorption.
