- Cariogenic
- adjective to indicate a conduciveness to the initiation of dental caries, such as a cariogenic biofilm or a cariogenic food.
- intermicrobial matrix
- material present between bacteria in dental biofilm; derived from saliva, gingival exudate. and microorganisms.
- Food impaction
- the forceful wedging of food into the peroiodontium by occlusal forces.
- Biofilm
- matrix-enclosed bacterial populations adherent to each other andor to surfaces or interfaces.
- Leukocyte
- white blood corpuscle capable of ameboid movement; functions to protect the body against infection and disease.
- Aerobe
- herterotrophic microorganism that can live and grow in the presence of free oxygen: some are obligate, others facultative; adj. aerobic
