Dens invaginatus is a developmental anomaly that results in an invagination of the enamel organ into the dental papilla prior to calcification of the dental tissues. Apical fenestration is defined as a defect in which the apices perforate the mucosa and are exposed to the oral cavity. These anomalies require a multidisciplinary management in order to give a better prognosis to the patient, since it acts as a retentive area of biofilm, affecting and deteriorating pulp and per radicular health. In this article we present a clinical case of apical fenestration by dens invaginatus in right upper lateral incisor, we describe different techniques for its management in which the participation of two specialties is incorporated: endodontic and periodontics, with the aim of recovering periodontal and per apical health.
