Unerupted but fully formed human third molar teeth were prepared for ultrastructural examination using three different fixatives; glutaraldehyde, a mixture of glutaraldehyde and p-formaldehyde and a picric acid-formaldehyde solution. These fixatives have reportedly differing rates of penetration of tissue. Odontoblast processes were found to be limited to the inner-third of crown dentine in all teeth, irrespective of the fixative used.
使用三种不同的固定剂对未萌出但已完全形成的人类第三磨牙进行超微结构检查；戊二醛、戊二醛和对甲醛的混合物以及苦味酸-甲醛溶液。据报道，这些固定剂对组织的渗透速率不同。无论使用何种固定剂，在所有牙齿中均发现成牙本质细胞突起仅限于牙冠牙本质的内三分之一。
