Abstract

A rare case of benign cementoblastoma is reported. Active cementoblasts adding cementoid tissue were observed histologically by means of specific staining for unmineralized matrix of hard tissue. A polarizing microscope and an x-ray diffractometer were used to clarify the cementum-like tissue of benign cementoblastoma. The collagen bundles of tumor tissue showed irregular and random arrangements under polarized light. The qualitative analysis revealed that the mineralized component was composed of low-crystalline hydroxylapatite.

摘要

报告了一例罕见的良性成牙骨质细胞瘤。通过对硬组织未矿化基质的特异性染色，组织学观察到活跃的成牙骨质细胞添加类牙骨质组织。使用偏光显微镜和X射线衍射仪来阐明良性成牙骨质细胞瘤的牙骨质样组织。肿瘤组织的胶原纤维束在偏振光下显示出不规则和随机排列。定性分析表明，矿化成分由低结晶度的羟基磷灰石组成。
