牙釉质内部空隙容积约为0.2—5%。但是,不适当的标本制备技术妨碍了对釉质孔隙的直接观察。包埋和切片前,为使釉质部份脱矿,所必须进行的粗糙的化学处理,切开硬组织时的震动和破坏造成釉质中的人为空间,致使不可能识别和确定任何自然空间的存在。不进行脱矿,而切开牙釉质的尝试甚至会导致自然结构的更严重的破坏。我们在用电子显微镜观察人牙釉质微孔 Enamel volume within the gap is about 0.2-5%. However, inappropriate specimen preparation techniques prevent direct observation of enamel pores. Prior to embedding and sectioning, rough chemical treatment necessary to demineralize the enamel, vibration and disruption upon incision of the hard tissue causes artificial space in the enamel, rendering it impossible to identify and determine the existence of any natural space . Without demineralization, attempts to incise enamel can even lead to more severe damage to the natural structure. We are observing human enamel micropores with an electron microscope
