Caries risk assessment Flashcards
(23 cards)
What are the pathological factors of caries?
poor plaque removal
frequent sugar consumption
inadequate fluoride
reduced saliva flow
What are the protective factors that promote remineralisation?
effective plaque removal
healthy diet
brushing 2x daily with fluoride toothpaste
professionally applied fluoride
normal saliva flow
preventative/therapeutic sealants
What are some caries indicators?
may be linked to disease, but not necessarily cause it
previous disease
attitude to dental care and prevention
cariogenic diet
home care
morphology (deep pits and fissures, poor margins/restorations, dentures/orthodontic appliances)
MH
quality and quantity of saliva
What effect can some medications have intraorally that can lead to caries?
reduction of saliva flow -> xerostomia
pt has loss of cleansing and buffering action of saliva
some medications can contain glucose, sucrose or fructose -> oral environment becomes more acidic
On the caries risk assessment, what makes a patient low risk?
only ticks in low risk column
On the caries risk assessment, what makes a patient moderate risk?
ticks on both low and moderate risk columns
On the caries risk assessment, what makes a patient moderate risk?
one or more ticks in high risk column
What does the caries risk assessment ask about?
attendance record
education and motivation
family dental history
medical history
diet
tooth morphology
previous disease or dental treatment
saliva
plaque control
patient home care
fluoride use
If a patient is low risk, when may their recall interval be?
if below 18, 12 months
if 18+, 24 months
How should moderate risk patients be managed?
additional fluoride therapy to prevent becoming high risk
fissure sealants
diet advice
OHI
fluoride rinses should be advised
more frequent recall and radiographic evaluation
bitewings recommended every 18-24 months
What saliva reducing factors may high risk patients have?
medications
radiation treatment
systemic illness
How often should the recall period be for high risk patients?
3 months
How often should radiographic evaluation be for high risk patients?
6 - 12 months
What is casein phosphopeptide?
remineralising agent of enamel derived from milk protein casein
milk protein and its derivatives have caries protective properties
What does tooth mousse contain?
casein phosphopeptide in the form of amorphous calcium phosphate CPP-ACP also known as recaldent
this stabilises high concentrations of calcium and phosphate ions with fluoride to form nano clusters
not suitable for anyone with milk allergy
What does ICDAS code 0 mean?
sound tooth surface
no evidence of caries after air drying
What does ICDAS code 1 mean?
visual change in enamel
opacity or discolouration at pit or fissure
seen after air drying
What does ICDAS code 2 mean?
distinct visual change in enamel when wet
lesion must be visible when dry
What does ICDAS code 3 mean?
localised enamel breakdown
without dentinal involvement
when wet and prolonged drying
What does ICDAS code 4 mean?
underlying dark shadow from dentine
What does ICDAS code 5 mean?
distinct cavity with visible dentine
What does ICDAS code 6 mean?
extensive cavity with visible dentine
more than half the surface
How often should caries sealed teeth be checked radiographically?
6 months
