Regional Odontodysplasia in Primary Teeth: A Case Report.

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.
