This case report presents an 8-year-old female patient with delayed eruption and gingival enlargement in the upper left quadrant. Clinical and radiographic examinations confirmed RO (regional odontodysplasia), with findings of hypomineralization, poorly developed roots, and ghost-like teeth. RO a rare, non-inherited dental condition, mainly affects the dentin and enamel of a specific localized group of teeth and maxilla is most commonly affected. It is characterized by hypoplasia, hypocalcification and a recognizable "ghost-like" appearance on radiograph. The patient had a history of calcium deficiency, which was addressed with supplementation. A conservative approach, including restorative treatment for carious teeth and periodic follow-ups, was adopted to monitor eruption status and plan future rehabilitation. Hence this case emphasizes how crucial it is to manage RO using a multidisciplinary strategy in order to maintain jaw development and functional results.
