Abstract
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.关键词
