Q

What is the recommended restorative material of choice for class v cavities and why?

A

Glass polyalkenoates, as they release and reuptake fluoride and they are adhesive to tooth substance

Q

Other than poor OH and diet, what other aetiology could cause class V carious lesions?

Q

What class of occlusion is more prone to incisal trauma? And why?

A

Class II occlusion , as your incisors will be much more prominent

Q

In shade matching, what does it mean to take the “value” of teeth?

A

The dimension that indicates lightness of colour (0-10: 0 being pure black and 10 being pure white)

Q

Why would we used an approximal strip between teeth when acid etching class III cavities?

A

To protect the adjacent tooth from etch which may damage and bond it upon light curing.

Q

What is the purpose of a bevel?

A

Increases surface area for bond

17
Q

what is a class II cavity?

A

Mesial and distal cavities in posterior teeth

18
Q

What should be used to simulate the missing wall of a class II cavity when placing an amalgam restoration?

A

A matrix band

19
Q

When using a matrix band, what else could be used to aid the retention and adaptation of the band?

A

A wooden wedge

20
Q

Why is a chemically cured resin cement (such as scotchbond-1) used after bonding agent when placing bonded amalgam?

A

As it will adhere to the bonding agent and will mechanically lock amalgam in place when it sets

21
Q

What is nano-leakage?

A

Where dentine is demineralised to a greater depth than bonding resin penetrates

22
Q

Where on a tooth, is resin composite at most risk of shrinkage and why?

A

In regions where moisture control is difficult, such as gingival margin.

23
Q

When placing composite in increments, what type would you use to try and relax stress at cavity margins?

A

Flowable composite

24
Q

What is the use of pre-polymerised inserts?

A

Minimise contraction on curing

25
Q

how long should you wait between curing cycles?

A

30 seconds

26
Q

Why might you use a post cure after finishing a restoration?

A

This increases surface cross linking and enhances wear resistance

27
Q

When restoring a class IV cavity, why should the matrix band used while acid etching be removed and replaced before carrying out placement of resin composite?

A

Because the matrix strip will be wet after acid etching and could impair polymerisation of resin composite

28
Q

What is the pre operative matrix formed from when using this technique to restore class IV cavity?

A

Impression silicone putty

29
Q

Why might you pre-wedge a posterior tooth prior to matrix band placement?

A

So that the wedge adjusts its position in the periodontal ligament to maximise the chances of establishing a good contact point when matrix band is placed

30
Q

What instrument might you select to adapt a matrix band?

A

Burnisher

31
Q

What shade of composite takes longer to cure? Dark or light?

A

Dark

32
Q

Why do darker shades of composite take longer to cure than lighter shades?

A

Because pigments in the dark shades limit the light transmission and reduce the degree of polymerisation

33
Q

What is the benefit of using pre-polymerised resin composite inserts in posterior teeth?

A

Minimises contraction of resin composite and aids contact point establishment
