The aim of the present study was to evaluate under scanning electron microscopy the ability of different chemically reactive solutions to form a protective layer on dentine. The materials selected were an oxalate solution, a collagen-oxalate solution, a collagen-oxalate solution plus glutaraldehyde and a saline control solution. Small dentine fragments, obtained from extracted human teeth, were treated with the various chemical solution for 60 seconds. All samples were then examined in a Jeol scanning electron microscope. The preliminary observations suggest that dentine may be covered by a mixture of oxalate crystals and collagen producing a homogeneous layer of reactive agents.
本研究的目的是在扫描电子显微镜下评估不同化学反应性溶液在牙本质上形成保护层的能力。所选材料为草酸盐溶液、胶原草酸盐溶液、胶原草酸盐溶液加戊二醛以及生理盐水对照溶液。从拔除的人类牙齿获取的小牙本质碎片，用各种化学溶液处理60秒。然后所有样本在日本电子扫描电子显微镜下进行检查。初步观察表明，牙本质可能被草酸盐晶体和胶原的混合物覆盖，从而产生一层均匀的反应剂层。
