| 摘 要： | 目的:介绍自行设计标准牙片持片器的设计、工作原理,并评价用该持片器拍摄牙片的可重复性。方法:选择具有健康、完整牙列志愿者20例。同一牙位拍摄2组牙片,一组为咬翼片,另一组为标准牙片投照装置拍摄的定位牙片,拍摄间隔为1h,获得2组20对牙片。测量釉牙骨质界-牙槽嵴顶距离(CEJ-AC)及邻牙釉牙骨质界点间距离(CEJ-CEJ)。结果:主观评价显示该投照装置的可重复性好,传统咬翼片可重复性较差,前后2次投照咬翼片CEJ-AC及CEJ-CEJ差值比标准牙片大,差异有显著性(P<0.05)。结论:使用标准牙片持片器拍摄的牙片可重复性好于咬翼片,可明显提高牙片图像的可重复性。 |

| Abstract: | Objective:To introduce a self-made film holder for standardized alignment of intraoral film and to evaluate its validity.Methods:The film holder,consisting of film backing,bite block and indicating part,was made of a kind of transparent material.20 patients were photographed using the film holder for serial dental films and another 20 patients were photographed using conventional bitewing instrument.The distance between the cemento-enamel junction and alveolar crest and the distance between cemento-enamel junction of adjacent teeth were measured on the serial films taken in the two groups.Results:The films taken by the use of film holder showed greater reproducibility than those by bitewing.Variables changes were significant smaller in film holder group than those in bitewing group.Conclusion:The film holder can be used as a instrument for standardized alignment of intraoral film. |
| Keywords: | Standardization of intraoral film Film holder Reproducibility |
