Posteruptive Intracoronal Resorption in a 9-year-old with Molar Incisor Hypomineralization: A Case Report.

Objectives: The case report highlights the management of late-stage sequelae of preeruptive intracoronal resorption (PEIR) with molar incisor hypomineralization (MIH).

Materials and methods: A 9-year-old patient presented with occlusal cavitations in her upper and lower permanent molars with vascularized tissue seen within the dentin, without any connections with the dental pulp, and no evidence of carious activity within the lesion. The affected teeth were debrided, and Biodentine™ was placed to preserve the vital pulp. The permanent molars were restored with Hall crowns, and the case was followed up for 2 years.

Results: The patient remained asymptomatic throughout the follow-up period. The resulting increase in the bite following the placement of the Hall crown settled within 2 months. Pulp vitality was preserved, and no further resorptive activity was seen in the dentition.

Conclusion: Preeruptive intracoronal resorption may go unnoticed and may later present with late-stage manifestations. Patients with PEIR and MIH may end up with an exposed resorptive lesion due to posteruptive breakdown, which may be managed conservatively using Biodentine™.

Clinical significance: Resorptive lesions can be conservatively managed without compromising pulpal health. Their early detection and differentiation from dental caries can prove pivotal in the preservation of the affected teeth.
