Dental Plaque 1

The dental cuticle consists of which two layers?

1

The outer layer of the dental cuticle resembles the

The inner layer of the dental cuticle resembles the last secretion of the

1

Which of these are functions of the acquired pellicle?

1

The acquired pellicle forms as calcium from enamel dissolves in . These are charged ions. Salivary are charged and are therefore attracted to the charged calcium ions. This permits formation of the pellicle. This deposition of occurs in around 2-3 after prophylaxis.

1

The acquired pellicle is composed of mostly...

1

The presence of stannous fluoride alters the pellicle amino acid composition resulting in more glycine and serine.

1

Some examples of oral microenvironments are:

mucosa
surface of the tongue
T surfaces
C epithelium
As

1

The acquired pellicle penetrates a small distance into the enamel - the sub surface cuticle.

1

Where is the thickest pellicle found?

1

Where is the thinnest pellicle found?

1

Mycobacteria form part of the oral flora

1

Where is calculus most commonly found?

Dental plaque is composed of

1

Which bacteria is a bridging bacteria?

1

What are some long range pellicle interactions?

1

What are some short range pellicle interactions?

1

P gingivalis is an example of a...

1

Where does bacterial colonisation of the pellicle begin?

1

The pioneer group of dental plaque are...

1

As the biofilm increases in thickness, the initial colonisers are replaced with shaped bacteria which creates a favourable environment for gram and shaped bacteria.

1

Collaboration between bacteria to break down complex substrates is an example of what?

1

Bacteria producing bacteriocin is an example of what interaction?

1

Bacteria occupying niches and prevent colonisation is an example of what interaction?

1

The double time of biofilm thickness decreases as time elapses

1

Fissure plaque is dominated by

1

Approximal plaque is dominated by

1

Many organisms are proteolytic in crevice plaque

1

Spirochaetes and anaerobic streptococci are almost exclusively isolated from appliance plaque

The fitting surface of appliances tends to harbour

As disease progresses toward periodontitis, what changes are seen?
