Aggregatibacter actinomycetemcomitans (Aa) (formerly Actinobacillus actinomycetemcomitans) and Porphyromonas gingivalis (Pg) are the major pathogenic bacteria species in the etiology of periodontal diseases, whereas the normal oral flora related to the disease are Prevotella intermedia (Pi), Tannerella forsythia (Tf) and Treponema denticola (Td) (7-9).
