Apexogenesis in young permanent canine with pre-eruptive intracoronal resortion: case report. Rev. Estomatol. Herediana [online]. 2019, vol.29, n.1, pp.80-88.

The permanent teeth have an incomplete development and root formation at the time of its eruption, the pulp tissue is responsible for completing the process of root formation by means of odontoblasts that produce dentin, if it is affected by trauma, carious lesion, Pre-eruptive intracoronal resorption (PEIR) and / or fracture, pulp vitality is altered and pulp necrosis may even occur, which will cause an interruption of the normal radicular formation. For the treatment of immature permanent teeth that have suffered some type of injury, but still maintain pulp vitality, the procedure of apexogenesis with added mineral trioxide (MTA) can be considered as a viable option, due to the biocompatibility and capacity of induce the formation of hard tissues. In this case report we present a tooth with a history of PEIR, treated by apexogenesis with MTA, achieving favorable results in terms of thickening of dentinal walls, root development and maintenance of pulpal vitality.

Keywords : Apexogenesis; immature root apex; apical closure; pulpotomy; calcium hydroxide; MTA.
