Regional odontodysplasia (RO) is an uncommon, nonhereditary, odontogenic developmental disturbance characterized by hypoplasia and hypocalcification of the dental tissues that produce so-called "ghost teeth." This report describes a case of a 2.5-year-old girl who came to the clinic with RO affecting her right maxillary arch. The distinguishing characteristics of this case were the involvement of both the primary and permanent dentitions and the early occurrence of odontogenic abscesses that required the patient's hospitalization. Ultrastructural analysis revealed dental tissue failures that compromised the integrity of the involved teeth, justifying the high susceptibility to caries that was clinically observed. Follow-up was characterized by periodic prosthetic adjustments to maintain the patient's ability to masticate and for social interaction, beyond allowing normal development of her maxillofacial complex. Patients with RO require individualized treatment planning and close follow-up with a multidisciplinary approach.
区域牙发育异常（RO）是一种罕见的、非遗传性的牙源性发育障碍，其特征是牙组织发育不全和钙化不足，形成所谓的“鬼牙”。本报告描述了一名2.5岁女孩的病例，她因右侧上颌牙弓出现RO前来就诊。该病例的显著特点是乳牙列和恒牙列均受累，且早期发生牙源性脓肿，导致患者住院治疗。超微结构分析显示牙组织缺陷损害了患牙的完整性，这解释了临床上观察到的患牙对龋齿的高度易感性。随访的特点是定期进行修复调整，以维持患者的咀嚼能力和社交互动能力，同时促进其颌面复合体的正常发育。RO患者需要个体化的治疗计划，并采用多学科方法进行密切随访。
