11. dental caries Flashcards
what is the cure for caries?
none
only prevention
what to do with caries?
prevent
remove
restore ……
when is a dental caries reversible?
in early stages
treatments for caries?
-simple restortion
- replacement restoration
- root canal therapy
- extraction
what does the treatment of caries depend on?
- signs and symptoms
- damage done
- patient preferences
- cost
- time
what is dental caries?
plaque related disease, dependant on presence of simple sugars in the diet, driven by frequency of eating simple carbohydrates, modified by fluoride, salivary flow and composition of saliva
what causes caries?
- time
- substrate (sugar)
- bacteria (plaque)
- susceptible tooth surface
where does plaque form?
- pit and fissures
- interproximal
- smooth surfaces
- root surface
what are contact points for plaque?
- interproximal
- hard to see
- hard to clean
what is secondary caries?
caries that form around a previous filling
how can dentists increase your risk of caries?
- around margins of restorations
-plastic restorations - crowns, bridges, inlays, onlays
- around orthodontic appliances
- around removable partial dentures
what does iatrogenic mean?
illness caused by medical professional
how do we reduce the risk of caries?
- reduce intake of sugars
- remove plaque
- increase exposure to fluoride
- tip balance towards remineralisation
name 2 classes of caries?
primary
secondary
describe primary caries?
caries lesions developing on intact, natural tooth surfaces
describe secondary caries?
recurrent caries, which develops next to an existing restoration
what is coronal caries?
Extremely deep caries extends through the entire thickness of dentine and bacteria are likely to be in contact with the pulp
what is root caries?
affects the root of the tooth
where are posterior interproximal caries?
between your back teeth
where are anterior interproximal caries?
between your front teeth
if there are multiple carious lesions, what would be the aetiology?
lack of oral hygiene and poor diet
what would be a result of low salivary flow?
caries due to low buffering capacity
why do we want to detect caries early?
- give caries-prevention advice
- reduce/ eliminate restorative intervention
how do you visually identify caries?
surface destruction and enamel discolourations
how do you detect caries that aren’t visual?
conventional or digital radiographs
what is the dark areas on a radiograph a sign of?
dental caries - where dentine has been decalcified
what are non operative managements of dental caries?
- dietary analysis
- reduce amount of simple carbohydrates (reduce substrate) - oral hygiene instructions
- remove plate regularly (reduce bacteria on teeth)
- tooth brushing and interdental cleaning - increase fluoride exposure
- tip balance towards remineralisation
what is hypoplasia?
incomplete development of tissue of the teeth
what is abfraction?
stress related trauma of the teeth
there is a strong relationship between what in caries?
- position
- extent
- shape of prepared cavity
- final restorative material
