The authors suggest a method to assess the quality of filling dental contact surfaces, based on determination of the relative contrast index (RCI) of the x-ray image of interdental septal apexes at the site of filled and intact teeth on the same image. Analysis of their own findings has lead the authors to a conclusion that assessment of the tooth filling with the use of periodontal and hygienic indexes is not strictly consistent because it is subjective, whereas the RCI permits a follow-up of changes in the mineral content of the bone in the examined site over time.
作者提出了一种评估牙齿邻面充填质量的方法，该方法基于测定同一X线影像上充填牙和完整牙部位的牙间间隔顶端X线影像的相对对比指数（RCI）。作者通过对自身研究结果的分析得出结论，即使用牙周和卫生指数评估牙齿充填情况并不完全一致，因为这是主观的，而RCI可以追踪所检查部位骨矿物质含量随时间的变化。
