目的
研究口腔锥形束CT(CBCT)在评价牙槽骨缺损方面的作用。
方法
拍摄10 例牙周病患者全口数字化根尖片和CBCT,分别在医用显示器上观察分析256 颗牙位近远中、颊舌向的牙槽骨缺损情况。
结果
数字化根尖片和CBCT 均可以显示近远中牙槽骨情况,两者之间差异无统计学意义;在数字化根尖片上不能准确判断牙槽骨缺损是位于颊侧或舌侧,CBCT 可以准确显示颊舌向牙槽骨缺损情况,CBCT 明显优于数字化根尖片。
结论
CBCT比根尖片更有利于牙槽骨缺损的诊断。
Objective
To study the effect of cone beam CT (CBCT) in assessment of alveolar bone defection.
Methods
Ten patients with periodontosis were selected for study. Each patient was taken full mouth intraoral periapical digital images and CBCT. Images were viewed on digital medical monitor. The periodontal bone of 256 teeth was evaluated with periapical digital image system and CBCT system respectively.
Results
Both intraoral periapical digital image system and CBCT system could clearly show the alveolar bone defects in medial-distal orientation.There is no significant difference between two systems according statistic analysis. However, the alveolar bone defects in lingual-buccal orientation could not be shown accurately on intraoral periapical digital image, it was able to be distinguished clearly on CBCT.
Conclusion
CBCT has more advantages than intraoral periapical digital images in evaluating alveolar bone defection.
