Intrusive luxation is considered one of the most severe dental trauma and may result into several complications, as radicular resorption and dental loss. This paper describes the intrusion of upper right central incisive, with incomplete rhizogenesis of a 10-year-old boy after an accidental fall. Endodontic treatment was realized with intra-canal medication with calcium hydroxide. After the accident, there was a clinical and radiographic follow-up for 2 years, and it was observed tooth repositioning, absence of external radicular resorption and radicular apex closure. This case report aimed the effectiveness of an endodontic treatment, in order to minimize the complications caused by intrusive luxation in a permanent tooth, with open apex.
