Q
what is the acquired salivary pellicle?
A
thin layer forms on teeth in seconds of cleaning smooth colourless translucent initially bacteria free derived from salivary glycoproteins
4
Q
in what 3 ways is the salivary pellicle protective?
A
1 glycolproteins and calcium phosphate from saliva are adsorbed to tooth surface = most resistant to tooth wear
2 restricts the diffusion of acid from sugar breakdown in the mouth
3 contains antibacterial factors
5
Q
what antibacterial factors are in the salivary pellicle?
A
antibodies IgG, IgA, IgM
complement
lysozyme
