Typical errors in teeth roentgenography reproduced in experiment, indicate that considerable disproportional distortions of images of anatomical structures which are decisive for radiodiagnosis, may occur in these cases. These distortions influence the accuracy of assessment of the condition of periapical tissues, marginal parts of the alveolar process, cavity sizes, and the actual end of the root of the canal. Standardization of intraoral roentgenography is based on a strict position of the patient's head, angle of inclination and alignment of a tube. Specialized P3-1 film should be used. Its processing should strictly correspond to the instructions of a manufacturing factory otherwise the quality of an image is deteriorated and an effective equivalent dose on the vital organs is increased.
实验中重现的牙齿X线摄影典型错误表明,在这些情况下,对于放射诊断起决定性作用的解剖结构图像可能会出现相当大的不成比例的失真。这些失真会影响对根尖周组织状况、牙槽突边缘部分、龋洞大小以及根管根尖实际情况评估的准确性。口腔内X线摄影的标准化基于患者头部的严格位置、球管的倾斜角度和对准情况。应使用专门的P3 - 1胶片。其冲洗过程应严格符合生产厂家的说明,否则图像质量会变差,重要器官上的有效当量剂量会增加。
