Diaz et al (2006) [42] have found that the initial colonizer on enamel surfaces are mainly streptococci followed by Neisseria pharyngis and Gemella haemolysans. These bacteria were considered by the authors to be a core group, providing the basis for the subsequent colonization of facultative and obligate anaerobes.
