Diagnosis and clinical management of pre-eruptive intracoronal resorption – a case report

Bianca Fiorentin Moura, Gustavo Ricardo Silveira, Sinval Adalberto Rodrigues-Junior


The pre-eruptive intracoronal resorption is a caries-like lesion frequently located in dentin underneath the dentin-enamel junction in the occlusal face of the tooth crown. Due to the resemblance with carious lesions, this lesion is often referred to as `pre-eruptive caries’, although its pathogenesis has no correlation
with the carious mechanism. Objective: This case report describes the diagnosis and clinical management of a permanent second molar presenting intracoronal pre-eruptive resorption, highlighting the possible clinical conducts associated. Case report: Diagnosis of the condition was accidental, through routine panoramic radiograph taken for orthodontic reasons. The therapeutic option involved the surgical exposure of the non-erupted tooth, exposure of the lesion
and removal of the tissue from the resorbed area. Restoration was performed using glass ionomer cement followed by composite resin. At the 9-month follow-up the patient presented no further clinical symptom of recurrence of the resorption or pain. Conclusion: Despite being a relatively rare condition, clinicians should be aware of the possibility of PEIR occurrence and perform a cautious radiographic examination.
