The human oral cavity is an open growth system which shelters a great variety of microorganisms capable of adhering to the surfaces of their anatomophysiologic constituents. Continuous adaptation and compatibility between the coexistence of such microbial populations and the health of human beings gives these microorganisms an ecologically balanced saprophytic condition characterized by symbiosis and antibiosis situations. A diet rich in sucrose diet may, however, disrupt this balance and induce the growth and settlement of anatomophysiologic bacteria that are responsible for major infections of the oral cavity (Adelmann, 2005).
