The present studies were performed to obtain data on the low-temperature ashing (lta of dentine. Observations of colour and acid solubility, measurement of weight loss, and chemical analyses of carbon, hydrogen, and nitrogen assessed the ashing efficiency. The LTA method was sufficient to deproteinize dentine powder below 300 mesh. The determinations of calcium, magnesium, and phosphorus in dentine showed no significant differences between LTA, muffle furnace ashing (MFA), and wet ashing. The carbonate content was not significantly different after drying and LTA, but apporximately 48% carbonate was lost using MFA. X-ray diffraction patterns of dentine powder showed no detectable changes before and after LTA treatment compared to the patterns after treatment by MFA and/or ethylenediamine extraction.
进行本研究以获取有关牙本质低温灰化（LTA）的数据。通过观察颜色和酸溶性、测量重量损失以及对碳、氢和氮进行化学分析来评估灰化效率。LTA方法足以使300目以下的牙本质粉脱蛋白。牙本质中钙、镁和磷的测定结果显示，LTA、马弗炉灰化（MFA）和湿式灰化之间无显著差异。干燥和LTA处理后碳酸盐含量无显著差异，但使用MFA时约48%的碳酸盐会损失。与MFA和/或乙二胺萃取处理后的牙本质粉X射线衍射图谱相比，LTA处理前后的图谱未显示可检测到的变化。
