A radicular cyst associated with carious teeth is a very common odontogenic lesion in the oral cavity, but calcifications in residual radicular cysts are quite rare. We report one such case where a routine pre-implant radiographic assessment revealed a mixed periapical radiopaque radiolucent lesion in the right maxillary central incisor region. Histological and radiographic studies show that there is a slow increase in the mineralized deposits within the cyst lumen with time. This becomes prominent histochemically in cysts more than 8 years old and radiographically 6 years later, as seen in our case. In this paper we would like to highlight the importance of a residual radicular cyst with calcifications in the differential diagnosis of a mixed periapical radiopaque radiolucent lesion.
与龋齿相关的根囊肿是口腔中非常常见的牙源性病变，但残根囊肿中的钙化是相当罕见的。我们报告了一例这样的病例，在常规的种植前影像学评估中，发现右上颌中切牙区域有一个混合性根尖周不透射线的透亮病变。组织学和影像学研究表明，随着时间的推移，囊肿腔内的矿化沉积物会缓慢增加。在我们的病例中，这种现象在超过 8 年的囊肿中组织化学上表现得更为明显，6 年后在影像学上也表现得更为明显。本文我们想强调在鉴别混合性根尖周不透射线的透亮病变时，伴有钙化的残根囊肿的重要性。
