%X Regional odontodysplasia (RO) is a rare developmental abnormality of epithelial and mesenchymal dental tissues. Due to its poorly understood etiology, assessing and discussing related clinical cases of this dental anomaly is crucial to guide professionals in improving its treatment and outcomes. This article aimed to report the case of a 9-year-old male patient who presented to our department with the main complaint of absent eruption of permanent left mandibular quadrant teeth. This is the first case reported in China from a patient with multiple cutaneous nevi on the face and neck, and based on the retrieved clinical and radiographic features, we described and discussed the treatment and etiology of RO.
