The most common of the supernumerary teeth in humans are mesiodentes, which arise in the midline of the maxilla between the central incisors. The most common pathologic findings associated with a mesiodens are retention of the adjacent incisors, malposition, and diastema. The development of a dentigerous cyst in association with an impacted mesiodens is relatively uncommon. We report the case of a 35-year-old man with an extensive dentigerous cyst associated with a mesiodens who presented with a painful swelling in the left nasolabial area. We discuss the imaging findings in this case, particularly the contribution of computed tomography, and we review the literature on this interesting condition.
人类最常见的多生牙是正中牙，出现在上颌骨中切牙之间的中线处。与正中牙相关的最常见病理表现是相邻切牙滞留、错位和牙间隙。与阻生正中牙相关的牙源性囊肿的发生相对少见。我们报告一例35岁男性病例，其患有与正中牙相关的广泛牙源性囊肿，表现为左侧鼻唇区域疼痛性肿胀。我们讨论了该病例的影像学表现，尤其是计算机断层扫描的作用，并回顾了关于这一有趣病症的文献。
