CBCT追踪抗生素剂在年轻恒牙根尖诱导成形术中的临床应用研究

目的：探究锥形束CT（CBCT）用于追踪抗生素剂在年轻恒牙根尖诱导成形术的临床应用价值。方法：选择45例患儿,包括根尖孔尚未充分发育的患牙共52颗,均为各种原因导致的牙髓炎或根尖周炎,常规性根管清理消毒后,采用抗生素糊剂行根尖诱导成形术,每隔3个月复查一次,共随访1年,拍摄X线根尖片及CBCT片观察根尖情况,比较两种方法的诊断准确度。结果：本组52颗患牙,CBCT片观察根尖发育成功48例,成功率为92.31%（48/52）,X线根尖片观察根尖发育成功39例,成功率为75.00%（39/52）,组间差异有统计学意义（P〈0.05）。结论：CBCT用于追踪抗生素剂在年轻恒牙根尖诱导成形术具有较高的成功率,值得临床推广应用。

Clinical application of CBCT tracking antibiotic agent to young permanent teeth apexification

Objective：To explore the clinical value of the cone-beam CT（CBCT） for tracking antibiotic agent in young permanent Apexification＇s. Methods： 45 cases of children including the apical foramen of the teeth were not fully developed a total of 52 were all causes of pulpitis or periapical. 52 teeth were given apexification by antibiotic paste line after routine root canal disinfection,and reviewed once every three months following for 1 year in which shooting X-ray films and CBCT apical root tip sheet , the diagnostic accuracy of the comparison of the two methods were observed and compared. Results： Of 52 teeth,CBCT slice observed 48 （92.31%） cases of apical development success,and X line apical root tip sheet observed 39 cases （75.00%） in which the difference between groups was statistically significant （P〈0.05）. Conclusion： CBCT for tracking antibiotic agent in young permanent apexification has a high success rate,which is worthy of clinical application.
