Unicystic ameloblastoma (UAM) in the pediatric population is a rare clinical entity that has not been well addressed in the literature. Radical approaches affect a growing young patient's physical and psychological development, so conservative approaches are widely used for management in children. This report describes the case of a 9-year-old girl with UAM of the mandible, which also involved the impaction of the first and second premolars. Marsupialization with orthodontic treatment was performed to shrink the lesion and upright the first premolar involved in the tumor. Ten months after marsupialization, the lesion had healed entirely. The combination of conservative surgery and orthodontic treatment effectively shrank the lesion, preserving mandibular growth, preserving the involved first and second premolars, and promoting the eruption of the teeth.
Keywords: marsupialization; orthodontic treatment; tooth eruption; unicystic ameloblastoma.
