摘要
目的评价数字化X线摄影和传统X线摄影在根管治疗中的临床应用价值。方法回顾性分析行根管治疗术的213例单纯慢性牙髓炎或慢性根尖周炎患者的影像学资料,纳入评估的牙齿共267颗,根据其接受的检查方法分为观察组(采用数字化X线摄影)和对照组(采用传统X线摄影),其中观察组136例(157颗),对照组77例(110颗),对两种检查方法进行准确度及清晰度比较。结果数字化X线摄影与传统X线摄影符合率为91.08%(143/157),其中有23颗牙齿根充的数字化X线摄影结果为恰填,而传统X线摄影结果为超填。观察组上尖牙、上磨牙的根尖X线摄影的清晰度与对照组比较,差异有统计学意义(P<0.05),而两组其他牙齿的差异均无统计学意义。结论根尖数字化X线摄影可能取代传统X线摄影而作为根管测量与充填的评价手段。
Objective To evaluated the value of clinical application of digital X-ray photography and traditional X-ray photography in root canal therapy.Methods Imaging data of 213 patients with simple chronic pulpitis or chronic periapical periodontitis who accepted root canal therapy in our hospital were retrospectively analyzed,and a total of 267 teeth were included for assessment.They were divided into observation group（digital X-ray photography adopted） and control group（traditional X-ray photography adopted） according to examination methods.Among them,there were 136 cases（157 teeth） in observation group and 77 cases（110 teeth） in control group.Comparisons of accuracy and sharpness were conducted between these two examination methods.Results Coincidence rate of digital X-ray photography to traditional X-ray photography was 91.08%（143/157）,of which digital X-ray photography of 23 teeth root canal showed correct fill-in,while traditional X-ray photography demonstrated over fill-in.Compared with the sharpness of periapical X-ray photography of upper canine and molar in observation group and those in control group,differences were statistically significant（P〈0.05）,and the other teeth in two groups showed no statistically significant difference（P〈0.05）.Conclusion Periapical digital X-ray photography probably replaces traditional X-ray photography to be a root canal measurement and filling evaluation tools.
