7
Q
Communication:what are the 3 age groups?
A
style of communication and advice given will vary between age groups
adults, young people, children
8
Q
patient motivation:
A
regardless of the help of the dental team, some patients are not interested in their own OH and are unwilling to follow advice
9
Q
mental capacity:
A
as people get older health conditions will affect the mental functions e.g. dementia so the understanding and retention of info being given may be forgotten
10
Q
In regards to patients general health, how may this affect oral hygiene?
A
some medical and physical conditions will cause oral disease development in some patients, while other conditions affect the patients ability to carry out effective OH
11
Q
what are the causing factors of dental caries?
A
- high sugar diet NMES
- poor oral hygiene
- stagnation areas e.g. overhangs, occlusal fissues, abutments (dentures).
- bacteria within the plaque biofilm + sugars = acid
12
Q
What are the causing factors of gingivitis and periodontitis?
A
- poor OH
- stagnation areas e.g. gingival crevice
-failure to treat and eradicate the ginigvitis allowing the inflammation to progress to periodontitis
13
Q
dental plaque biofilm is..
A
plaque
14
Q
What is plaque
A
thin transparent layer of saliva, oral debris and normal mouth bacteria that sticks to the tooth surface it can only be removed by cleaning.
15
Q
What causes plaque to grow thicker?
A
food debris
16
Q
If plaque is in contact with a tooth surface caries will develop unless the plaque is removed.
A
17
Q
If plaque is in contact with the gingiva, gingivitis and then periodontitis will develop unless the plaque is removed.
A
18
Q
caries is mainly a disease for those of what age groups?
A
children and young adults
19
Q
periodontal disease develops at what stage in life?
A
Later in life
It can be found in younger patients but this is uncommon
20
Q
In regards to sugars what age group is more likely to eat more?
A
young children - their teeth are more vulnerable to caries
21
Q
what is saliva?
A
the watery secretion from the salivary glands that bathes the oral cavity to keep the tissues moist.
22
Q
What does saliva protect our oral cavity against?
A
- caries by promoting remineralisation of early enamel caries due to its MINERAL CONTENT and BUFFERING effects
- Periodontal disease by its cleansing and antibacterial properties due to its ANTIBODY and WHITE BLOOD CELL content and ANTIBACTERIAL ENZYMES.
23
Q
How does saliva promote overall health of the mouth?
A
lubricating and cleansing effects
24
Q
what is xerostomia?
A
dry mouth
25
Patient who have xerostomia are at more risk of getting what oral diseases?
caries and periodontal disease
26
what do acids cause?
enamel demineralisation
27
What are the 3 examples of advice we will give to a patient in relation to caries prevention?
- increase the tooth resistance to acid attack - fluoride
- modify the diet - fewer cariogenic foods and drinks and reduce frequency intake
- control the build up of bacterial plaque - good OH routine
28
what is the main cause of periodontal disease?
poor oral hygiene
29
What are the 3 examples of advice we will give to a patient in relation to periodontal disease?
- control the build up of bacterial plaque - good OH
- modify the contributory factors - smoking
- control the host response - frequent dental attendance for monitoring and evaluation and intervention - 3 months.
30
Plaque forms within what time frame?
hours
31
Oral hygiene techniques that are given to a patient to carry out at home:
- toothbrushing - effective technique and recommended toothpaste
- interdental cleaning - brushes or floss
- suitable mouthwashes
32
Toothbrushing is the method used to remove..
surpagingival plaque + food debris on the tooth surface
33
Should the patient be told to rinse after brushing?
No - the patient should spit not rinse as it removes the residual toothpaste and prevents chemical constituents from continuing to act in the mouth e.g. flouride
34
What is the recommended age that parents should brush their childs teeth up until?
8 years old
35
95% of Toothpastes in the UK contain fluoride, what is the normal PPM for fluoride for children and adults?
sodium monofluorophosphate and sodium fluoride at 1400PPM
36
High fluoride toothpastes should contain what PPM?
between 2800 and 5000ppm for use of adult patients with high caries risk
37
What else does toothpaste contain?
triclosan with zinc this acts as an antiseptic plaque suppressant
38
what do sensitive toothpastes contain?
arginine, NovaMin and stannous fluoride
39
what do whitening toothpastes contain?
mild abrasives as micro-crystals - use of biological enzyme systems
40
toothpastes that contain titanium dioxide and phosphosilicates help to protect the teeth against...
acid erosion + help enamel repair
41
what is dental floss used to do?
achieve interdental plaque removal
instructions on the usage is important
42
why are flossettes easier to use than floss?
patients can floss with one hand - makes it easier with posterior teeth
43
Indental brushes are used to clean:
interdentally around every tooth and they are also used with orthodontic appliances.
44
What are interspace brushes usually used for?
help the patient to clean in wider interdental spaces as well as fixed ortho appliances
45
Are woodsticks usually recommended?
No as they can easily become stuck into the gum and cause problems if used incorrectly
46
The main aim of interdental aids is?
to dislodge food particles and accumulated plaque from the interdental areas of the teeth.
mesial and distal surfaces of teeth
47
general use mouthwashes contain various ingredients to promote good OH for example...
sodium fluoride - provides TOPICAL fluoride application to teeth
triclosan - chemical that suppresses the formation of plaque
48
what ingredient does the mouthwash contain that is given to patients with soft tissue inflammation:
hydrogen peroxide
49
specialist mouthwashses are advised to patients suffering from both acute and chronic periodontal infections they contain:
chlorhexidine - antiseptic plaque suppressant
50
Can loose food debris be removed by sugar-free chewing gum or finishing a meal with detergent food?
Yes - it is recommended
51
Examples of detergent foods:
raw, firm, fibrous fruits or vegetables e.g. apples, pears, carrots and celery.
52
What does having HARD cheese at the end of a meal stimulate?
salivary flow, neutralises acid and enhances remineralisation of enamel = calcium content
53
Chewing gum should be advised for what time of the day?
after a meal not continuously
after 10 mins should be disposed of
will increase the amount of tooth wear that occurs
54
fluoride occurs naturally in water and is added artifically to water supplies in other areas during the process of water fluoridation.
55
fluoride replaces the hydroxyapatite crystals with:
fluorapatite crystals = fluoride protects the teeth from developing caries.
56
topical fluoride is
application of various oral health products
57
systemic fluoride is
fluoride that is taken internally with food/drink products
58
Topical fluoride that patients can use:
- fluoride toothpastes
-Not to rinse after brushing
- flouride mouthwash
- dental floss
59
Children under 3 years old should be using toothpastes containing no less than what PPM?
1000
60
Topical fluoride that the dental team can provide for a patient:
- fluoride varnish for patients with high caries risk contain 22,600PPM fluoride, reduce the indicience of caries by 30-40%
- Fluoride varnish - duraphat
- high concentration fluoride toothpaste on perscription
61
What is the risk of perscribed fluoride supplements?
fluorosis
62
Examples of systemic fluorides:
- fluoridated water supplies 1ppm
- fluoride drops and tablets - for children on perscription to be taken up until the age of 13 years old
63
What does fissure sealant do?
used to seal the natural stagnation areas of pits and fissures therefore preventing the patient from acid attacks and avoiding onset of dental caries.
64
What is enamel fluorosis?
Occurs when excessive fluoride is ingested during enamel formation.
dotted white areas in the enamel surface which very in severity.
restorative techniques can disguise this
65
Reducing which foods will help prevent dental caries:
- free sugars NMES
- dietary acids from daily food and drink intake
66
After eating the oral cavity will experience an acid attack what level will the PH go to?
5.5
67
what is the neutral PH level?
7
68
Free sugar foods should be ate at meal times only what is the reason behind this?
Because the acids involved are neutralised to some extent by the buffering action of saliva and the extent of demineralisation will be reduced.
69
Foods containing "hidden sugars" can be identified by reading the contents label of each product.
70
What was the reasoning behind the "Eatwell guide" being made?
help advise the public on what constitutes to a healthy balanced diet by dividing standard food plate into thirds and indicating the amount of products that should come from each group
71
