Feb14 M2-Dental Caries Flashcards
common example of systemic diseases linked to oral health
diabetes, obesity and caries are linked together by high sugar intake
oral manifestation of boulemia
erosion of teeth surface due to vomiting
oral manifestation of ulcerative colitis
pustules on oral mucosa (and in rest of gut too but easier to see in the mouth)
xerostomia def + in what pop
lack of saliva. frequent in aging population
consequences of xerostomia
- drop in QoL
- more prone to oral infection
- more prone to caries lesions
most common cause of xerostomia + other causes
medication (asthma puffers for ex). other: chemo, radiation therapy, Shogern’s syndrome (affects sudation and salivary glands)
crystal meth effect on the mouth and why
teeth lesions bc causes xerostomia + has corrosive agents
HIV patients first thing seen (in the mouth)
hairy leukoplakia
HIV oral manifestations
- hairy leukoplakia
- oropharyngeal candidiasis (on angle of lips = angular cheilitis, top of tongue which is the dorsal tongue, on palate)
oral manifestation of severe immunosuppression + what happens
necrotizing ulcerative periodontitis. rapid loss of bone around teeth: painful, teeth are mobile, smells bad
what’s the cause of the drop in dental decay incidence over the past decades
presence of fluoride in toothpaste and water
main risk factor for caries lesions
poverty (and lack of education)
3 age groups where prevalence of untreated caries peaks and where they have the worst burden
6, 25, 70
why real teeth not necessarily the best thing for elderly
if can’t clean them bc frail and limited in movements, dentures are better
dental caries disease process vs dental caries lesions
- disease process = happening all the time to all teeth of everyone. can be controlled but not prevented
- lesions = result of the disease process
chemical basis for caries disease process
bacteria metabolize fermentable sugars and produce acid INTO the dental plaque
how plaque pH (plaque is not a good thing) and amount of enamel (the good thing) change with time and why
-pH varies (up and down)
-enamel demineralization and remineralization all the time
don’t eat = higher pH and remineralization
pathological factors in caries disease process
- acid producing bacteria
- fermentable carbs (in the food)
- insufficient saliva flow
protective factors in caries disease process
- fluoride
- saliva flow and buffering capacity
- regular removal of dental plaque
steps before get cavitated lesions
- caries disease process
- caries lesions
- non-cavitated lesions
- cavitated lesions
TF dental caries = cavity in the tooth
false. can have caries lesions without cavities
2 reasons to catch caries lesions as early as possible
- easier to arrest
2. prevents restoration (that’s a procedure) of a tooth which is a bad thing to have bc many complications
visible part of the tooth and its 2 portions
crown. outside = enamel. layer inside that is dentin
vital part of the tooth name + content
pulp. has nerves, blood vessels, cells, etc.
