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

本病例报告强调了对伴有磨牙切牙矿化不全（MIH）的萌出前牙冠内吸收（PEIR）晚期后遗症的处理。
一名9岁患者的上下颌恒牙磨牙出现咬合面空洞，牙本质内可见血管化组织，与牙髓无任何连接，病变内无龋病活动迹象。对患牙进行清创，并放置Biodentine™以保留活髓。用Hall冠修复恒牙磨牙，并对该病例进行了2年的随访。
在整个随访期间，患者均无症状。放置Hall冠后咬合升高在2个月内稳定下来。牙髓活力得以保留，牙列中未观察到进一步的吸收活动。
萌出前牙冠内吸收可能未被注意到，后期可能出现晚期表现。患有PEIR和MIH的患者可能由于萌出后牙体组织破坏而最终出现暴露的吸收性病变，对此可使用Biodentine™进行保守处理。
吸收性病变可在不影响牙髓健康的情况下进行保守处理。早期发现并将其与龋齿区分开来对于保留患牙至关重要。
