Q

what does pem lead to in the saliva

A

low protein diet- PEM can lead to decrease in the calcium content of saliva and protein content and the proteins form protective layer of the saliva
and the buffering- IgA and lysozymes rate reduced
reduced fluid rate

Q

what can vit E deficiency lead to

A

disturb enamel formation in animals

RARE IN HUMAN

22
Q

give examples of protein found in saliva

A

arginase and ferritin

23
Q

what does arginase do in the saliva

A

bacteria feed on the arginine in the plaque which produces urea and ornithine

24
Q

why is the urea helpful in the arginine pathway

A

as then the bacteria feeds on the urea and arginase and releases ammonia to create a favourable alkaline environment

25
what can vit D deficiency lead to
disturbed calcium and phosphate metabolism- rickets | eg slight enamel hypoplasia
26
what is enamel hypoplasia seen as clinically
rough pitted enamel can lead to the adherence of food and plaque better more fragile
27
which three acids does pyruavte produce
lactic acid formic acid acetic acid
28
what is PEM
protein energy malnutrition | can affect both the tooth structure and saliva composition
29
what does pem lead to in the tooth structure
associated with enamel hypoplasia
30
when are sugars particularly bad
when mixed with sticky starch based food eg cake or eaten as solids
31
give examples of plaque polymers
glucan and fructan
32
give examples of protein found in saliva
arginase and ferritin
33
what does arginase do in the saliva
bacteria feed on the arginine in the plaque in the plaque
34
why is the urea helpful in the arginine pathway
as then the bacteria feeds on the urea and arginase and releases ammonia to create a favourab;e
35
how much water should we drink a day
2. 5 L a day | 1. 8 L from beverages
36
what can be the issue with dehydration
reduces the salivary flow rate increased caries risk can be an issue for athletes with sports drinks which have high sugar
37
which three acids does pyruavte produce
lactic acid formic acid acetic acid
38
why are some carbohydrates more cariogenic than others
-due to the stickiness of the carb eg toffees -formation of extracellular and intracellular plaque polysaccharides which change the environment for bacteria- leading to more cariogenic bacteria being present promoting bacterial adherence
39
what is the cariogenicity of starch
low- less acidogenic
40
when are sugars particularly bad
when mixed with sticky starch based food eg cake or eaten as solids
41
give examples of plaque polymers
glucan and fructan
42
what is absent in the plaque overnight if it is starved
fructasn
43
is fruit bad to eat
no as it can increase salivary flow considered as low cariogenic risk- intrinsic sugar but picking at fruit not good
44
is fruit juices ok to eat
more cariogenic and have less salivary stimulus | more extrinsic sugar added too
45
describe milk
contains around 5% lactose sugar but is cariostatic contains calcium and phospahet which inhibit demin and promote remin non casein proteins bibnd to enamel and protect surface
46
what does milk contain which protects against caries
non caesin proteins
47
what does chocolate contain
cocoa factor- anticariogenic
48
what does liquorice contain
glycyrrhiziinic acid - caries preventative
49
what is an issue with liquorice
electrolyte imbalance
50
describe sugar substitutes
bulk sweetners all are calorific non cariogenic - xylitol is anticariogenic
51
what can sugar substitutes cause
osmotic diarrhoea
52
what are intense sweetners
more sweet than sucrose added in small amounts | not cariogenic
