Case report: A 12 years-old boy, with a preliminary radiographic diagnosis of pre-eruptive radiolucent lesion, made in 2016. In 2019, the diagnosis was confirmed through clinical observation after placing a separator orthodontic elastic in the interproximal space and radiographic exam. The treatment implemented was a full removal of the lesion, followed by dental bonding with total-etch (Prime&Bond®NT - DENTSPLY SIRONA) and restoration with composite resin (Synergy® Compact colour A2/B2 - Coltène Whaledent®). Follow-up after 6 months was performed.
Discussion: Pre-eruptive intracoronal radiolucency is characterized by a well-circumscribed radiolucent area, within the dentine of unerupted teeth and close to the amelodentinal junction. There is yet no consensus regarding the clinical management of this lesion, due to a low predictability of its clinical course. The difficulty to perform a differential diagnosis with other lesions is aggravated, in particular with dental caries, at least until the eruption of the affected tooth.
Conclusion: There are no reports of progression or reactivation of the lesion after dental restoration. Therefore, this seems to be the most appropriate therapeutic option, according to the particularities of each clinical situation. However, more prospective and retrospective studies are required in order to develop clinical guidelines for the treatment of this type of crown lesions.
