Traumatic injuries caused by intrusion account for 4-22% of the damage in anterior primary teeth and are generally related to axial impact. They are more frequent in children aged 1-3 years because of the additional high resilience and flexibility of the primary teeth supporting structures. The treatment decision will depend on the magnitude of the trauma and on the displacement position. In most cases, radicular displacement occurs towards the labial bone plate. The clinical decision of spontaneous re-eruption and observation were adopted. This study aims at presenting a literature review illustrated with two case reports of patients having intrusive luxation injuries of the primary incisors.
