摘要:
目的 觀察錐形束計算機體層攝影術(CBCT)檢測口腔正畸中牙槽骨、牙根吸收狀況的效果。方法 選擇2016年1月~2017年7月我院進行口腔正畸治療患者92例,均接受CBCT檢測,比較治療前、后中切牙牙槽骨厚度、牙根吸收情況。結果 治療前后下頜、上頜根尖部、根中部、牙頸部牙槽骨厚度比較,差異無統計學意義(P>0.05);治療后,下頜、上頜側切牙牙根長度[(20.63±1.20)mm、(19.41±0.85)mm]、中切牙牙根長度[(21.12±1.19)mm、(21.74±1.02)mm]小于治療前[(21.84±1.52)mm、(20.39±1.27)mm]、[(22.84±1.37)mm、(22.31±1.19)mm],差異有統計學意義(P<0.05)。結論 口腔正畸患者存在一定牙根吸收現象,但未見明顯牙槽骨改建,CBCT檢測可對口腔正畸患者牙根吸收進行評估,以期為臨床預防牙根吸收提供確切信息。
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.
