ABSTRACT
This study identifies the major pathogens that constitute the normal oral flora of Malaysians and elaborates on their pathogenic potential. Major oral microorganisms identified by their 16S rDNA sequences include Streptococcus pneumoniae, Staphylococcus aureas, Streptococcus mitis and Neisseria subflava in the gingival crevice, Streptococcus oralis, Rothia mucilaginosa and Kingella oralis on teeth surface, Streptococcus infantis, Streptococcus pseudopneumoniae, Actinomyces viscosus on tongue surface. Organisms identified non-pathogenic included Pseudomonas aeruginosa in the gingival crevice, Streptocccus sanguis on teeth surface and Lautropia sp. on tongue surface. The presence of pathogenic organisms may have profound implications on the health of individuals harbouring them. Knowledge of the type of bacteria that inhabit the oral cavity is important in predicting and preventing not only dental diseases but also the associated systemic complications caused by them.
