what carious lesion begins as subsurface demineralization; acid from bacterial action on the tooth surface passes through microchannels in the enamel, demineralization occurs, and eventually a white spot can be seen clinically
incipient
true or false. The use of fluoride can help reduce incipient caries.
true
Are food particles neede in the mouth for biofilm to form?
no
Certain microorganisms and their toxic products can cause periodontal infectious diseases, where are these microorganisms found?
in biofilm
Where do the pathogens that can cause periodontal infections exist?
in biofilm
_________ provides protection and gives the organisms that cause periodonatl infections increased resistance to antibiotics
biofilm
there is a majority of aerobic, gram-positive organisms, and the number of organisms and white blood cells is relatively low in what type of pocket?
healthy sulcus

diseases sulcus
Effects of the inflammatory factors from periodontal infection have been demonstrated on What 5 systemmic diseases?
cardiovascular diseases
adverse pregnancy outcomes
diabetes
pulmonary diseases
stroke
a loosely adherent mass of bacteria and cellular debris that frequently occurs on top of dental biofilm where biofilm removal is neglected
materia alba
a 'White material' that distinguishes itself clinically as bulky, soft deposit that is clearly visible without application of a disclosing agent. It is white, or grayish white, and characteristically may resemble cottage cheese
materia alba
a product of informal accumulation of living and dead bacteria, desquamated epithelial cells, disintegrating leukocytes, salivary proteins, and possibley a few particles of food debris
materia alba
true or false. surface bacteria in contact with the gingiva contribute to gingival inflammation. tooth surface demineralization and dental caries are seen frequently under materia alba
both are true
Can materia alba be removed with a water spray or oral irrigator? Can dental biofilm?
yes
no
