dietary advice Flashcards
(36 cards)
what are the important factors in caries control?
plaque control
use of fluoride
dietary modification
what factors place students at a high risk for caries?
- high sugar intake
- inadequate brushing habits
- no fluoride exposure
- irregular dental attendee
- medically compromised
- xerostomia
what medical and dental disorders can caries lead to?
overweight and obesity
type 2 diabetes
dental caries
what methods should we use on a patient with suspected caries?
diet analysis
investigation on fluoride intake
medical history
oral hygiene practices
bitewing radiograph
why would you use a bitewing radiograph while trying to identify caries?
do the job with minimum exposure
would Diet Coke cause caries?
no it would cause erosion
what dietary factors are associated with caries incidence?
- amount of fermentable carbohydrate eaten
- sugar concentration of food
- physical form of carbohydrate
- oral retentiveness
- frequency of eating snacks and meals
- length of interval between eating
- sequence of food consumption
what studies prove the relationship between caries and sugar?
vipeholm study
Turku study
the Stephen curve
according to WHO how much should the intake of free sugar be?
under 10% of total energy consumption
(50g/person/day)
what carbohydrates cause caries?
sucrose
fructose
glucose
maltose
what do patients need to recorded on a diet sheet ? how many days should be recorded?
all food and drinks consumed
the amount
the time
- over 4 days including 2 work days and 2 leisure days
who should fill out a diet sheet for a child?
mother
what should be stressed to a patient before filling out a diet sheet?
comply fully and assess their diet honestly
- don’t change diet because its being recorded
what should we highlight to a patient on their diet sheet?
highlight sugar rich foods and drinks
number of sugar exposures
consistency of the food (dry/ sticky)
sugar drinks taken right before bed
give examples of food with high hidden sugar?
baked beans
breakfast cereals
tomato sauce
‘plain’ biscuits
what advice should you give to a patient/ parents after analysing a dietary sheet?
reduce snacks containing sugar
avoid adding sugar
save sweets to special times of the week
eat sweets all at the one time
don’t eat/ drink after brushing at night
avoid food night before bedtime
give 3 features that dietary analysis feedback must be?
acceptable
practical
affordable
(give praise)
what is extrinsic erosion caused by?
acid originating outside the body
usually ph 2.5 or weaker
what causes intrinsic erosion?
stomach acid reaching teeth
ph of 1
why is intrinsic erosion worse than extrinsic erosion?
acid is typically 100 times stronger so much more destructive
what is the most common cause or pathological tooth wear?
erosion
what does preferential wear of dentine lead to?
‘cupping’ of the occlusal surfaces of the molars and incised edges of anteriors
what does the position and severity of erosion depend on?
source
type and frequency of exposure to acid
what is titratable acidity?
the number of hydrogen ions available for erosive attack rather than pH
