The great dilemma for the practitioner in endodontics is how far to penetrate with the instruments within the duct. For this reason, the real longitude of the different teeth in various ethnias and geographic zones of the same country is an important and characteristic data. This research was done through a tomographic analysis of the extracted teeth. A representative sample of the seven provinces of Costa Rica was taken, using 1470 roots of 980 teeth, 70 superior teeth and inferior, giving 210 roots in total per province. It was possible to determine the real longitudes of the different teeth of the costaricans. According to the methodology used, the sample was probable of the stratified type with the objective goal of assuring a representation of each one of the provinces of the country; the dental pieces were collected through private and public dental clinics. The results reflect teeth with similar measurements to other studies done in other parts of the world.
