Q

What does the HPC suggest has happened to the tooth and give a pulpal diagnosis?
S – Upper right first pre-molar
O – 6 days prior the tooth had fractured and been sore ever since
C – It was a dull aching pain, tooth was sensitive
R – Did not radiate anywhere else
A – No associated symptoms
T – Painful when touch, gives off short sharp pain which lasts a few seconds
E – TTP
S – constant 2/10 then when bite 7/10

A
  • Tooth was grossly carious and this caused it to be weakened. The crown has then fractured.
  • As the tooth is TTP suggests symptomatic periapical periodontitis.
  • Irrervisble pulpitis

Q

How does the mechanism of aspirin work to reduce the risk of heart attacks?

A

Aspirin works by irreversibly inhibiting the enzyme cyclo-oxygenase (COX-1) which is required to make the precurrser for thomboxane within platelets.
This reduces thromboxane synthesis. Thromboxane is required to facilitate platelet agregation and to stimulate further platelet activation

Q

How does a patient taking aspirin effect dental treatment?

A
  • According to the SDCEP guidelines as this patient is only taking aspirin do not interrupt the treatment or the dose.
  • patient will be more at risk to bleeding
  • Therefore when planning more invasive procedures like XLA, you should limit inital treatment area, stage extensive or complex treatment and use local haemostatic measures like stitches, surgicel and pressure.

29
Q

If patient admits to having poor OH and only brushes one a day. What advice can you give them to help imporve this?

A

TIPPS
- Need to exert a behavioural change with this patient explain to them the diseases and what can happen if something doesnt change
- Use aids like radiographs and pictures to help with this
- Make sure they understand
- Then can use disclosing tablets to show the areas in the mouth they need to focus on
- Show them the modifed bass technique and remind them to brush gums too with electric toothbrush 2x a day
- Higher fluoride toothpaste can prescribe this
- Interdental brushes to get riight shape and floss
- Then any other tools

30
Q

Patient says they have a poor diet with a lot of snacking on sugary treats. What would you do here?

A

The high sugar levels, combined with the high frequency outside of mealtimes are a breeding ground for bacteria and therefore caries. Patient was asked to fill out a diet diary (3 days one being weekend) and diet advice was given.

31
Q

What does a family history of periodontal disease suggest? and what can you do?

A
  • It is a risk factor
  • Prevention early on is important for these patients
  • As their immune system is more prone to causing bone loss as a result of bacteria
  • These patients have to have extremely good OH as they are genetically pre-disposed to more aggressive periodontis.
32
Q

How does periodontitis work simply? and how would you explain that to the patient?

A
  • In time plaque thats left on the teeth turns to calculus (this cannot be remove with OH anymore)
  • This calculus spreads below the ginigval margin. This bacteria present on the calculus irritates the gums and causes a chronic immune response as the source of the response hasnt been removed.
  • Your bodies natural immune response is to fight this with inflammation and fever, but by doing so your body also attacks itself and causes the bone and tissues to receed.
  • This causes pockets to form
  • These become abscesses that further the disease progression which can then spread throughout the body and cause severe health consequences.
  • If the source isnt removed eventualluy there will be no bone left and the tooth will fall out or have to be removed
33
Q

Why is smoking a risk factor for oral disease?

A
  • It causes vasocontriction to tissues in mouth which reduces ability to heal as well as reduced blood flow
  • slows down immune response
  • Increases chance of oral cancer
  • Leads to destruction of supporting tissues
34
Q

After quitting smoking how long does it take to improve gum health?

A

3months to a year

35
Q

With your patient being on so many different medications, what is a possible side effect and what effect does that have on the mouth?

A
  • Polypharmacy
  • This results in a decreased salivary flow rate, which increases the rates of caries and erosion of the mouth.

Acid acts as a buffer to acids and clears away bacteria and sugars out of the mouth

36
Q

How can older poorer restorations be a risk factor for oral disease?

A

They can have poor margins which act as a plaque trap and food trap for food.
These areas can also be more difficult to clean
Resulting in caries

37
Q

Your patient has a slight click on the LHS of their TMJ. What could this be due to?

A

His osteoarthritis is effecting the TMJ
Clenching, grinding and other parafunction habits

38
Q

What is black hairy tongue and is it serious?

A
  • Black hairy tongue is not serious
  • It is when the patient has a longer than normal papillae, this papillae can easily trap bacteria, food and other debris which stains the tongue black
39
Q

How do you treat black hairy tongue?

A

It is harmless you treat it by removing the causes and practising good oral hyigene
Also sucking on a peach stone can help

40
Q

Why did you only take one PA of the UR?

A

As when I first saw the patient upper and lower PA’s had been taken only 6 months prior. So i didnt have the justification (IRMER17) to repeat these. As the patient wasnt complaining of any pain or symptoms from these teeth.

41
Q

Why is pulp testing not always reliable. Especially in older people?

A

The pulp will reduce in size (sclerose) as the patient gets older and becomes less responsive to pulp testing.

42
Q

Why do you take a 6PPC before treatment starts?

A
  • To access the periodontal health and the identify the worse sites
  • Also gives you a baseline to compare with
43
Q

Why are diet diaries taken?

A
  • Diet diary was given to establish areas within the patient’s diet which could be responsible for high levels of caries. Then allow for more targeted advice.
44
Q

For you perio diagnosis what does each part mean?
Generalised, stage 3, grade C, unstable, risk factors of ex smoker and family history of periodontal disease.

A

Generalised periodontitis – more than 30% of mouth with pockets
Stage 3 – middle third of root for the worst sites of bone loss
Grade C – patient is 57 but there is more than 57% bone loss on the worst sites
Ex-smoker and family history of periodontitis– risk factors
Currently unstable – Have pockets of greater than or equal to 5mm.

45
Q

Why have you decided to make a partial acrylic denture for this patient instead of CoCr?

A
  • Acrylic is better as it is easier to add teeth to the design later. Which is good as this patient has teeth with poor prognosis
  • Furthermore, due to this patient’s periodontal disease you don’t want to be putting high levels of force onto the abutment teeth.
  • If I XLA any teeth will have to wait 3-6months for the tissues and bone to properly heal before you can start making CoCr
46
Q

Once you have carried out step 2 of the BSP guidance for perio. How long till you carry out a review 6PPC?

A

3months

47
Q

After quitting smoking how long does it take to see a real benefit and reduce in the risk of cancer?
Then how long does it take for a smoker to be the same as someone who has never smoked?

A
  • 1 year to 4 years
  • 20 years till someone who has never smoked
48
Q

What is asthma?

A

characteristised by inflammation of the area way

49
Q

What are the 3 main features of asthma?

A
  • Contraction of the smooth muscle
  • Excess production of mucous
  • Narrowing of the airways to the lungs
50
Q

What considerations are there for asthmatic patients in dentistry?

A
  • Stress can be trigger so make sure salm enviroment
  • Medications like steroids and inhalers can cause erosion, caries, poor wound healing and candida infections
  • Make sure they can lie back okay as can be diffciult for them to breath when lying flat
