In 1957 a woman was murdered in Oslo. Her left breast exhibited tooth marks. A man was arrested and sentenced to life imprisonment partly because of the dental evidence. He never admitted guilt and filed a petition for retrial. The present author was appointed as new dental expert. The material consisted of the fixed breast, models of the bite mark and models of the teeth of the convict, and several photographs. By means of visual examination, a magnifying glass, a lens stereoscope and a stereomicroscope characteristic details were noted. Stereoscopic picture pairs were taken, the material was studied by means of scanning electron microscopy and a stereometricgraphic plotting method permitting the outline of the tooth mark or the biting edge of a tooth to be registered in great detail in all three dimensions in the form of a contour map. This method has not previously been applied in the analysis of tooth marks in human skin. These examinations revealed no discrepancies but showed many corresponding characteristic features between the tooth marks and the teeth of the convict, resulting in the conclusion that it is highly probable that the tooth marks in the breast were made by the teeth of the convict.
1957年，一名女子在奥斯陆被谋杀。她的左乳上有牙印。一名男子被捕并被判处终身监禁，部分原因是牙齿证据。他从未承认有罪，并提交了重审申请。作者被任命为新的牙科专家。材料包括固定的乳房、咬痕模型和罪犯的牙齿模型，以及几张照片。通过目视检查、放大镜、透镜立体显微镜和体视显微镜记录了特征细节。拍摄了立体图像对，通过扫描电子显微镜和立体测量绘图方法对材料进行了研究，该方法可以将牙印或牙齿的咬边轮廓以等高线图的形式在三维空间中详细记录下来。这种方法以前尚未应用于人体皮肤牙印分析。这些检查没有发现差异，但显示出咬痕与罪犯牙齿之间有许多相应的特征，从而得出结论，乳房上的牙印很可能是罪犯的牙齿造成的。
