Total questions: 10
Worksheet time: 6mins
The main antibody found in the oral cavity is ....
IgG
IgM
sIgA
IgE
It is a calcium and zinc-chelating protein
lysozyme
calprotectin
agglutinin
histatin
It lyse bacterial cell by activating autolysin in the bacterial cell wall
peroxidase
lactoferrin
lysozyme
sIgA
It bind iron and make it unavailable to invading microbe
mucin
cystatin
histatin
lactoferrin
It hydrate and lubricate oral mucosa
defensin
agglutinin
lysozyme
mucin
It protect enamel from tooth-tooth and tooth-mucosa friction
Peroxidase
secretory leukocytes protease inhibitor
agglutinin
acquired enamel pellicle
Regarding commensal oral microbiota
contribute to host nutrition through the synthesis of vitamins
allows colonization of pathogenic bacteria
produce antagonist to inhibit susceptible extrinsic bacteria
contribute to immunity by inducing low level of circulating and secretory antibodies
Regarding sIgA
prevent microbial adherence on mucosal surfaces
bind free iron in saliva
maintain integrity of the epithelial barrier
bind to acquired pellicle thus aid in bacterial attachment to tooth surface for aggregation of bacteria
Regarding Von Ebner Gland Protein
is secreted from Von Ebner Gland
also secreted from minor gland in labial mucosa
is cysteine protease inhibitor
it involve in demineralization process
Regarding characteristic of salivary mucin.
highly soluble
strong adhesiveness
low elasticity
high viscosity
