摘要
目的探讨安氏Ⅰ~Ⅲ类错颌畸形患者在正畸治疗中应用锥形束CT的价值。方法选取2022年7月—2023年7月错颌畸形76例,分别给予曲面体层X线及锥形束CT检查,后依据结果给予正畸治疗,并再次行锥形束CT检查。将X线头影结果作为诊断金标准,比较2种方法诊断牙根吸收情况的准确率和治疗前后牙根体积变化情况。结果锥形束CT诊断牙根吸收的总准确率为88.16%(67/76)高于曲面体层X线检查的57.89%(44/76)(P<0.05)。和治疗前相比,治疗后患者右上中、右下侧、右上侧、右下中切牙及左上中、左下侧、左上侧、左下中切牙体积缩小(P<0.05)。结论安氏Ⅰ~Ⅲ类错颌畸形患者正畸治疗后有较高概率发生牙根吸收情况。锥形束CT具有操作简便、准确率高的特点,可清晰有效显示牙根吸收程度及体积变化情况,是一种快捷、有效且安全的辅助诊断方式。
Objective To investigate the value of conical beam CT in orthodontic treatment of patients with class Ⅰ-Ⅲ malocclusion.Methods From July 2022 to July 2023,76 patients with malocclusion were selected,and examined by curved body X-ray and conical beam CT respectively.Subsequently,orthodontic treatment was given according to the results,and conical beam CT was performed again.X-ray examination results were used as the gold standard to compare the accuracy of the two methods in diagnosing root resorption and the change of root volume before and after treatment.Results The total accuracy of cone beam CT in the diagnosis of tooth root absorption was 88.16%(67/76),which was higher than that[57.89%(44/76)]of curved body X-ray examination(P<0.05).Compared with those before treatment,the volume of the right upper middle,right lower middle,right upper middle,right lower middle incisor,left upper middle,left lower middle incisor,left upper middle,and left lower middle incisor were smaller after treatment(P<0.05).Conclusion There is a high probability of root resorption in patients with class Ⅰ-Ⅲ malocclusion after orthodontic treatment.Cone beam CT has the characteristics of simple operation and high accuracy,which can clearly and effectively display the degree of tooth root absorption and volume change,as a rapid,effective and safe diagnostic method.
