Case Report: Managing Odontoma and Molar-Incisor-Hypomineralization Challenges in Orthodontics

This clinical case report presents the comprehensive multidisciplinary management of a 15-year, 7-month-old female patient diagnosed with an odontoma-associated impaction of the mandibular right permanent canine and molar-incisor-hypomineralization (MIH). While previous studies have addressed these conditions individually, this case illustrates a unique combination requiring surgical, orthodontics, and restorative interventions. The patient presented with esthetic concerns and delayed eruption of the mandibular canine. Clinical examination revealed an Angle's Class I molar and Class II canine relationship, lingual crossbite of the maxillary right lateral incisor, impaction of the mandibular right permanent canine, retained primary canine, and MIH affecting both anterior teeth and first molars. The treatment plan involved surgical removal of the odontoma to facilitate orthodontic traction of the impacted canine. Subsequently, orthodontic treatment was initiated to correct occlusion and alignment. After successful space management and canine eruption, restorative procedures were carried out to improve the esthetics and function of MIH-affected teeth. This case highlights the importance of early diagnosis, interdisciplinary collaboration, and a customized treatment approach in managing complex mixed dental anomalies. The outcome demonstrated improved function, esthetics, and patient satisfaction.
