Plaque material on human teeth was investigated using histochemical techniques and scanning electron microscopy. A positive reaction for protein, cargohydrate, and lipids was seen around the fissures and in a well-defined band around the sides of the tooth corresponding to the highest contour. These regions are the location of dense aggregates of bacteria as seen with scanning electron microscopy. This study emphasizes the fact that considerable attention should be given to the cleaning of not only the occlusal surfaces but also the highest contour of the tooth.
使用组织化学技术和扫描电子显微镜对人类牙齿上的菌斑物质进行了研究。在裂隙周围以及牙齿侧面与最高轮廓相对应的一条清晰界定的带中，观察到蛋白质、碳水化合物和脂质呈阳性反应。正如扫描电子显微镜所见，这些区域是细菌密集聚集的位置。这项研究强调了一个事实，即不仅应高度重视清洁咬合面，还应重视清洁牙齿的最高轮廓。
