- Abstract -

The role of oral microflora in the etiology of various inflammatory periodontal diseases has been well established, and specifity may exist between bacterial etiology and periodontal diseases. Over 500 bacterial species exist in the human oral cavity, and may reside in the dental plaque biofilm above and below the gingival margin [1,2,3,4,5].

Among all the studies bacteria, five have shown the highest association with destructive periodontal diseases: Actinobacillus actinomycetemcomitans (Aa), Phorphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Tannerella forsythensis (Tf) and Treponema denticola (Td) [5,6].

Therefore, the revelance of having accurate diagnostic techniques for their identification and quantification is clearly justified.
