caries and erosion prevention Flashcards
dental caries
demineralisation of the tooth surface caused by bacteria producing acid
diet
refers to the customary allowances of food and drink taken in by a person day to day
carcinogenicity of sugars
sucrose most cariogenic with glucose and fructose
lactose and intrinsic sugars not a threat
added sugars or non extrinsic/free sugars bad
elimination of sugars
chewing
rinsing effect of saliva
what is clearance time dependant on
salivary flow rate age adhesive nature of food concentration of sugar in food time of day
what in food/foods reduce cariogenic potential of carbohydrates
phosphates
cheese
fluoride
xylitol
food diary
1 weekend 2 weekdays
time of day
snacking ect
what should be advised on diet
reduce freqruency and amount of sugar restrict sugars to mealtimes avoid snacking avoid processed foods encourage sugar free gum consumption encourage tooth brushing
dental erosion
irreversible loss of hard dental tissue due to chemical process of acid dissolution
- does not involve bacterial plaque acid
extrinsic sources for acid
food (citrus fruit, pickled, ketchup)
drinks (carbonated drinks, fruit juice, herbal tea)
lifestyle (mood enhancing drugs)
environments(swimmers, batter acid workers)
intrinsic sources of acid
medical (gastric acid reflux, vomiting, rumination)
psychological
(anorexia,bulimia)
why should you not brush immediately after eating/drinking
you are brushing acid into the tooth
