Dento-alveolar trauma and congenital absences are the most important causes of edentulism that are not associated with bacteria. However, the World Health Organization reports show that dental caries and periodontitis, two conditions of bacterial origin, are the most frequent oral diseases in humans [1]. These conditions might be avoided if an adequate oral preventive health policy is implemented, including preventive and educational measures that, regardless of the population s socioeconomic factors, have shown their effectiveness. Despite these facts, tooth extraction1, defined as the surgical removal of a tooth, is currently the most frequent surgical procedure in the world [1].
