What are the chances of caries happening Flashcards
what are the factors necessary for caries
tooth
flora
substrate
time
what factors affect the tooth and its susceptibility to caries
Age Fluorides Morphology Nutrition Trace elements Carbonate level
what factors affect the flora
strep, mutans
oral hygiene
what are the general risk factors
social status of the patient
what are the local risk factors
level of oral hygiene diet fluoride experience past caries experience ortho treatment
what are the 7 elements to a caries risk assessment
clinical evidence dietary habits social history fluoride use plaque control saliva medical history
what clinical evidence indicates high risk
dmft equal to or greater than 5 is high risk
caries in the 6’s at 6 years
3 caries in 3 years
ortho
what is dmft
decayed, missing and filled teeth
if it is lower case then it is primary teeth if it is upper case then it is permanent teeth
what dietary habits means high risk
equal to or greater than 3 sugar intakes per day
frequency
what type of carbs
how does the type of carbohydrate consumed affect risk
Highly processed refined carbs are more cariogenic than natural sugars i.e sucrose more cariogenic than glucose and fructose
why is tooth brushing times important
should be 20 mins at least between last meals and brushing
what does social history consist of
○ SIMD category ○ Education ○ Unemployment ○ Work stressors ○ Single parent families ○ Violence ○ Inequalities and access to health care Dependents
how does fluoride use indicate high risk
do they brush their teeth?
is there fluoride in water supply
how does fluoride lower caries risk
incorporated into enamel crystal to from fluorapatite which is more caries resistant than hydroxyapatite
bacteriocidal
interferes with bacterial adhesion
how does plaque control contribute to caries risk
poor oral hygiene:
Poor technique
Irregular brushing
Unassisted (very young/old or dexterity issues)
Access to toothbrush/toothpaste
Difficulty due to changes (mixed/dentition/orthodontics/gaps/recession)
what factors of saliva contribute to caries risk
Amount Flow Buffering capacity - we need saliva to buffer pH viscosity
what in the medical history can indicate caries risk
xerostomia drugs making side effects free sugars making medicines more palatable lactulose recreational drug use
what are social factors that indicate high caries risk in children
Mothers education is secondary only
Poor dental attender
Family unit - single parent, social class, unemployment
what are the health factors that indicate high caries risk in children
poor health/chronic sick
sugar based meds
what are the social and behavioral factors that should be considered for infants and toddlers
mothers caries rate prolonged nursing habits bottle pacifier at bed time cariogenic snacking no tooth cleaning little fluoride exposure
when should babies start brushing
eruption of first tooth - even if partial
who are the high risk adults
Level of education
Attends only when they identify a problem
Social difficulties
Sweet tooth with poor oral hygiene
Sugar contain meds or meds affecting saliva
Root caries
Secondary caries
