Ten cases of odontogenic myxoma (OM) and six cases of ameloblastic fibroma (AF) were subjected to comparative analysis by the AgNOR technique, in order to determine a possible difference in cell proliferation index between these lesions. The mean AgNOR number of the mesenchymal component of AF was compared with its epithelial component and the difference was not found to be statistically significant. The mean AgNOR index of the AF group was significantly higher than that of the OM group. Moreover, the mesenchymal component of AF demonstrated increased AgNOR numbers compared with that of OM (P<0.05). These results suggest that the epithelial and mesenchymal components of AF may have similar cell proliferative activity. However, the cell proliferative index of this lesion seems to be higher than that of OM.
对10例牙源性黏液瘤（OM）和6例成釉细胞纤维瘤（AF）采用核仁组成区嗜银蛋白（AgNOR）技术进行对比分析，以确定这些病变之间细胞增殖指数的可能差异。将AF间充质成分的平均AgNOR数与其上皮成分进行比较，发现差异无统计学意义。AF组的平均AgNOR指数显著高于OM组。此外，AF的间充质成分与OM相比，AgNOR数增加（P<0.05）。这些结果表明，AF的上皮和间充质成分可能具有相似的细胞增殖活性。然而，该病变的细胞增殖指数似乎高于OM。
