Regional odontodysplasia (RO) is a rare dental anomaly that affects the development of dental tissues, resulting in amorphous, hypocalcified, hypoplastic teeth with the characteristic radiographic appearance of "ghost teeth." This study aims to report the clinical case of a patient diagnosed with RO in primary teeth. A two-year-old boy was brought to a private clinic with complaints of delayed eruption and anomalies in the upper right primary teeth. Intraoral examination revealed significant changes in the shape, color, and structure of all upper right primary teeth, including enamel hypoplasia, conoid and flattened teeth, yellowish/brownish coloration, and associated gingival inflammation. Radiographic examination revealed a thin layer of enamel and dentin, with no contrast between them, a pattern characteristic of "ghost teeth." A conservative approach was adopted, including prophylaxis, application of fluoride varnish, guidance, and regular clinical and radiographic follow-up, aiming to maintain the health of the affected tissues and monitor the development of the permanent dentition. This case highlights the importance of early recognition of RO, which enabled an individualized treatment plan focused on preserving the affected teeth and promoting oral health.
局部牙发育异常（RO）是一种罕见的牙齿发育异常，会影响牙组织的发育，导致牙齿呈无定形、钙化不全、发育不全，具有“鬼牙”的特征性影像学表现。本研究旨在报告一例乳牙诊断为RO的临床病例。一名两岁男孩因右上乳齿萌出延迟和异常被带到一家私人诊所。口腔检查发现右上所有乳齿的形状、颜色和结构有明显变化，包括釉质发育不全、牙呈圆锥形且扁平、发黄/褐色以及相关的牙龈炎症。影像学检查显示有一层薄薄的釉质和牙本质，两者之间无对比度，这是“鬼牙”的特征性表现。采取了保守治疗方法，包括预防、应用氟化物 varnish、指导以及定期的临床和影像学随访，旨在维持受影响组织的健康并监测恒牙列的发育。该病例强调了早期识别RO的重要性，这使得能够制定个性化的治疗计划，重点是保留受影响的牙齿并促进口腔健康。
