Q

Why do we no longer use probing as the main method of detection of caries?

A

Probing can break surface of tooth and lead to more bacteria entering - plaque trap
The probe transfers cariogenic bacteria between different teeth
probing does not mean a better or more accurate diagnosis

A

Code 0 - sound tooth, no evidence of caries after surface drying
Code 1 - first visual change in enamel, white/brown discoloration at entrance to pits/fissures, after drying
Code 2 - distinct enamel change when wet, must also be seen when dry
Code 3 - localised enamel breakdown without dentine involvement, seen when wet and after prolonged drying
Code 4 - underlying dark shadow from dentine
Code 5 - distinct cavity with visible dentine less than half the surface
Code 6 - more than half the surface showing cavity with visible dentine

23
Q

What are the advantages of using transmitted light to detect caries?

A

Better in patients with posterior crowding as BW will produce overlapping and for pregnant women to avoid unnecessary radiation

24
Q

How does tooth separation help to detect caries?

A

Place separators/matrix bands between contact points - after 2 days feel gently with probe to detect cavity. Elastomer impression material can be used between teeth to record cavity if present

25
Q

How may laser fluorescence methods be inaccurate to detect caries?

A

Readings can be confused by staining and calculus so should be used in conjuction with conventional methods

26
Q

How does laser detect caries?

A

Emits light 655nm

laser light penetrates tooth

light is measured and intensity is an indication of size and depth of lesion

better for occlusal caries

27
Q

What factors indicate high risk of caries?

A

Medical history - disability, sjorgrens

dental history - past caries/restorations

oral hygiene - low frequency of tooth cleaning etc

diet - high sugar

saliva - stimulated and un-stimulated saliva flow is low

social and demographic factors - poverty, education, religion, unemployed

28
Q

How does a white spot lesion occur?

A

Enamel exposed to acids from microbial biofilm, mineral is removed from surface.

inter-crystalline spaces enlarge and become more porous

clinically has white spot appearance

29
Q

What is the response to caries in dentine?

A

Odontoblasts form tertiary dentine at pulp/dentine border - tubular sclerosis

30
Q

Which comes first infected or affected dentine?

A

Infected

31
Q

What are dead tracts?

A

empty dentinal tubules filled with air due to degeneration of OB processes (caries etc)

32
Q

What are transverse clefts?

A

Penetration of bacteria in the dentinal tubules which traverse at right angles to the tubules along the incremental lines of growth

33
Q

What is the defense to dentine caries?

A

Tubular sclerosis
tertiary dentine formation
reduction in permeability of the dentine
removal of bacterial mass and sealing it - allow patient to clean/OH/fluoride can arrest lesions and encourage reparative dentine

34
Q

What are the 3 types of caries management?

A

Non invasive/preventive, minimally invasive, restorative

35
Q

Describe preventive caries management

A
3 diet diary - assess
extrinsic and intrinsic acids
effective tooth brushing
salivary flow assessment
fluoride exposures - optimal levels
fluorides in gels, varnish, mouthwash, toothpaste etc
DBOH
36
Q

Why should we restore teeth?

A
Aids plaque control
prevent sensitive teeth
pulp is endangered
failed alternative preventative measures
function has been impaired
loss of contact point and subsequent tooth movement
aesthetic reasons
37
Q

When should surgical intervention for caries only be carried out?

A

Once cavitation has occurred

38
Q

What are the factors associated with compliance?

A
Disease
Patient
Operator
Treatment
support system
facilities
39
Q

What are the 3 operator variables that exist for compliance factors?

A
  • Explanations
  • Attitude towards the treatment
  • Quality of the therapeutic relationship
40
Q

Why is communication important? (6 points)

A
  • Patient trust
  • Patient involvement in decision making

  • Latent motivation; only need a “trigger”
  • Lacking motivation; difficult
46
Q

What are the 4 pre-requisites for change?

A
  • A problem exists which affects the patient personally
  • There will be an unwanted outcome – loss of teeth
  • There is a practical solution – adequate plaque control
  • The problem is serious enough to justify inconvenience/time/effort
47
