Describe the following influences on the Oral Microflora
Diet?
Saliva?
Gingival cervicular fluid
Microbial Interactions
Host factors
Diet-Chem. composition, physical consistency and frequency of intake
Saliva-flow rate, pH balance, antimicrobial factors, ex lysozyme
GCF-contains many antimicrobial components ex. IgA,IgG
Microbial interactions- some beneficial/harmful
Gaseous environment- Relative [O2] help to determine species distribution.
Host factors- Systemic disease, antibiotic use, oral hygiene.
