Forensic odontologists are often called upon to assist in the identification of bodies. Since identification of the body relies on comparison of the post-mortem chart with the ante-mortem record it is important that all restorations present in the deceased's teeth are identified and correctly charted. If a restoration is present in an ante-mortem record then its absence in the post-mortem chart means that the two records cannot belong to the same person. However, tooth-coloured restorations can be difficult to identify, especially in the less than ideal conditions under which the odontologist may have to work. This study was designed to evaluate a simple technique for identifying tooth-coloured restorations, exploiting the difference between the surface roughness of restorative materials and that of the surrounding tooth substance. A conventional dental probe was substituted for the bell of a stethoscope. Differences in the surface texture of the tooth are reflected in changes in the sound heard by the examiner. The modified stethoscope is a useful and easily fabricated device, which may reduce the likelihood of small tooth-coloured restorations going unnoticed in post-mortem examinations. The ability to detect fissure sealants using the device may also prove useful in epidemiological studies.
法医牙科学者经常被要求协助尸体鉴定。由于尸体鉴定依赖于死后图表与生前记录的比对，因此识别死者牙齿上所有的修复体并正确记录在图表中非常重要。如果生前记录中有某种修复体，而死后图表中却没有，那么这两份记录就不可能属于同一个人。然而，牙齿颜色的修复体可能难以识别，尤其是在法医牙科学者可能不得不工作的不太理想的条件下。本研究旨在评估一种利用修复材料与周围牙体组织表面粗糙度差异来识别牙齿颜色修复体的简单技术。用传统牙科探针代替听诊器的钟型探头。牙齿表面纹理的差异会反映在检查者听到的声音变化中。这种改良的听诊器是一种有用且易于制作的设备，它可能会降低在尸检中遗漏小的牙齿颜色修复体的可能性。使用该设备检测窝沟封闭剂的能力在流行病学研究中可能也会被证明是有用的。
