Q

What is the gold standard for moisture control? Why is it not often used in pads?

Dental dam

Due to pt compliance, may be distressing for pt, spacing of dentition makes it harder

Q

Why do we need good moisture control for fissure sealants?

A

The resin used to F/S is moisture dependant and for good bond everything needs to be dry or else F/S will fail - can end up with caries trapping under sealant

medically compromised
physical disability
xerostomia
long term poly pharmacy

47
Q

What would put a pt in higher caries risk via clinical evidence?

A

Caries in 6’s at 6 years is high risk
3 year caries increment being equal to/higher than 3 is high risk

48

55
Q

10-16

over 16 can have 5000ppmF

60
Q

Who can be prescribed 5000ppmF toothpaste?

A

> 16 yr olds

61
Q

What is fluoride varnish?

A

This is a high strength fluoride solution that is applied to the teeth to make them stronger and more resistance to any decay - it is applied 2x year in school and for high risk kids can be applied up to 4x year (school and dentist) - tastes of banana or bubblegum

62
Q

When can children have mouthwash?

A

After 6 if they can spit it out

63
Q

What is SDF?

A

SDF liquid contains silver and fluoride which work together to stop decay progressing further. It is a clear liquid, that has a temporary metallic taste while it is being painted on to teeth.
If your child is suffering from dental decay, it can progress rapidly, especially in baby teeth which have thinner enamel than adult teeth. By applying SDF liquid, your dentist can stop decay progressing which reduces the risk of toothache or infection. SDF liquid combined with improved oral hygiene and a change in diet can save teeth

64
Q

How is SDF applied?

A

o protect your child’s lips and gums, your dentist will first apply petroleum jelly (or an alternative) and also place cotton wool next to their teeth. Their teeth will then be dried.
The SDF liquid is painted on to the teeth for 1-3 minutes. Following this the teeth are dried a second time. Sometimes, the dentist may then place a filling over the top.
This is all done in one appointment. A second appointment may be made to come back 2-4 weeks later to check the teeth and apply more SDF liquid if needed.
SDF liquid is usually reapplied every 6 months.

65
Q

clinical procedure for SDF?

A
  1. dry tooth and clean tooth
  2. apply vaseline to gums and lips to protect
  3. use micro brush and apply SDF
66
Q

Advantages of SDF

A

It is a simple procedure that reduces sensitivity and slows down or stops tooth decay. In many instances SDF is more effective than fluoride varnish.
It can buy time for children who cannot currently manage dental treatment by stopping the decay getting worse until they can have further dental treatmen

67
Q

Disadvantages of SDF?

A

It permanently discolours the decayed area of teeth black. Healthy parts of the tooth do not discolour.
It can temporarily stain the skin, lips, gums and cheeks brown or white for 1-3 weeks, this will then disappear.
It can also discolour tooth coloured fillings, polishing these fillings can help remove this stain but it may stay visible at the join between the tooth and the filling.
In the unlikely event of SDF being accidentally spilled on clothes, it can leave a stain that does not come out.

68
Q

Alternatives to SDF?

A

Keeping the tooth under review, but it is likely the decay will get worse
Placing fluoride varnish Filling the tooth
Placing a silver cap/crown Removing the tooth
