Regional odontodysplasia (ROD) is a rare developmental anomaly involving both mesodermal and ectodermal components in a group of contiguous teeth. It affects the primary and permanent dentitions in the maxilla and the mandible or both, however, the maxilla is frequently involved. Although the etiology of the ROD is uncertain, it has been suggested that numerous other factors play a role. The treatment plan should be based on the degree of involvement as well as the functional and esthetic needs in each case. This article reports the case of a 5-year-old boy presenting a rare anomaly on the right side of the maxillary arch. The treatment performed was rehabilitation with temporary partial acrylic denture and periodic checkups. The extraction was followed by rehabilitation with dental implants. The main aim of this article is to provide valuable information to pediatric dentists about the review and treatment alternatives for ROD.
区域牙发育异常（ROD）是一种罕见的发育异常，累及一组相邻牙齿的中胚层和外胚层成分。它可影响上颌骨和下颌骨的乳牙列和恒牙列，或两者皆有，但上颌骨常受累。尽管ROD的病因尚不确定，但有观点认为许多其他因素也起作用。治疗方案应根据受累程度以及每个病例的功能和美观需求来制定。本文报告了一名5岁男孩上颌弓右侧出现罕见异常的病例。所进行的治疗是使用临时局部丙烯酸义齿进行修复并定期检查。拔牙后采用牙种植体进行修复。本文的主要目的是为儿科牙医提供有关ROD的评估和治疗选择的有价值信息。
