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

Resumo

The pre-eruptive intracoronal resorption is a carieslike lesion frequently located in dentin underneath the dentinenamel 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.
