The aim of this study was to determine the prevalence of dent invaginatus (ID) in children between 6 and 11 years old. A descriptive transversal clinical study was performed with patients from V and VI year students, supervised by a specialist in Odontopediatrics during 15 months from July 2011 and December 2012. The dental and medical history, as well as a clinical and radiographic evaluation was done to all the patients, following the protocol established by the Odontopediatrics Department. In a total population of 280 children, 13 % presented the abnormality from which 11.4 % were boys and 15.3 % were girls. The most affected piece was the maxillary lateral incisor. There was no statistical significant difference regarding the gender of children who presented ID (p = 0.318). The early diagnosis and treatment is important to avoid future complications.
