Card preview (24)
what factors are necessary for caries
tooth surface substrate - carbohydrate flora - bacteria, strep mutans time
what are the 7 factors for caries risk assessment
clinical evidence oral hygiene diet fluoride exposure saliva medication social status
what can be measured for someones clinical evidence
caries experience - dmft either primary or permanent
what causes white spot lesions
build up of plaque, acid produced, demineralisation of enamel but not cavitated
what is the consequence of white spot lesion on dentine
causes demineralisation of dentine, can get tertiary dentine formed
why are pits and fissures higher risk of caries
more likely to get food down here and stuck, but have reduced flow of saliva down for clearance, allows for demineralisation of enamel. also difficult for bristles of toothbrush to get down. the enamel at this region is also thinner, so gets into dentine quicker - fast spread
what are different strategies of intervention for prevention of caries
individual - specific education and prevention measures tailored to individual, caries risk assessment targeted population level - target the population at higher risk, fluoride varnish on high risk children’s teeth whole population - health education and promotion for everyone
what is the benefit of targeting the whole population
moves the distribution of whole population to a lower risk category - not just those high risk
what is proportionate universalism
targeting the whole population but increasing measures for those at high risk
what are the different levels of interventions
upstream - national, change in policies and programmes midstream - community level, training other people downstream - chairside dental education
what are risk indicators for children
bottle feeding, parental smoking and oral hygiene, diet, fluoride exposure, socioeconomic status
what are the 8 preventative measures
tooth brushing technique diet advice fluoride toothpaste fluoride varnish fluoride supplementation sugar free medication radiographs fissure sealants
what diet advice can be given to prevent caries
water and milk only - if need juice, only at meal times and as diluted as possible, and through a straw sugary foods and snacks at mealtimes only cheese can be given after meal - anticariogenic snack ideas - cheese and crackers, bread sticks, crisps
what is nursing caries
caries in children who have been given a bottle to go to bed, suck on it all night. constantly low pH in mouth. caries on upper anteriors and molars
what bottle should children use
free flowing spout
what levels of fluoride should be in toothpaste for standard risk
under 4 - 1000ppm 4-16 - 1000-1500ppm
what levels of fluoride should be in toothpaste for high risk
under 10 - 1500ppm 10-16 - 2800ppm 16+ - 5000ppm
what are the classifications of caries
extent - enamel only or enamel and dentine cavitation activity - active or inactive, demineralising or re location - primary or secondary site - occlusal, approximal, smooth surface, root surface
what are the 2 components of accuracy
sensitivity - % of correctly identified disease specificity - % of correctly identified health
what is required for clinical examination in detecting caries
dry tooth surface, light, probe but not sharp (ball ended) and time
what can be used in helping to diagnose caries
magnificiation, radiographs, ICCMS
what are advantages and disadvantages of using magnification to detect caries
improves sensitivity for D1, much greater detail seen, but smaller field of vision - D3 sensitivity not as good
what are advantages and disadvantages of using radiographs to detect caries
allows more surfaces to be seen - approximal, good for D3, but not as good for D1 - also exposes patient to ionising radiation
what is ICCMS
drying every surface of tooth for 30 seconds, and spending more time detecting caries
