Unit 311- oral health Flashcards
how is oral health applied ethically
-fair
-specialities
-structional modifications
-domiciliary, community, hospitals
give some cultural social trends
-baby teeth not important
-no fluoride
-loose teeth with age
-low health literacy
-fasting
-known as expensive
how does plaque form
-bacteria attaches to receptors of pellicle
-pellicle binds to glycoproteins of salvia
-bacterial layer late colonisers bind to early
name some campaigns
-stoptober
-national smile month
-mouth cancer friction
-dental buddy
-smile4life
plaque turns to calculus
calcified calcium phosphate
name 4 oral diseases
1- caries (bacteria erodes though enamel)
2- gum disease (initial to highly severe)
3- oral cancer
4- birth defects
toxins in plaque is caused how
plaque releases acids decreases the pH and mineral is lost
difference between symptoms ging and perio
perio has sensitive, bad breath, pain, receding, bone loss
what is false pocketing
epithelial attachment does not migrate
what is demineralisation
loss of minerals from enamel and dentine 1st stage of decay
what is white spot lesion caused by
loss of calcium and phosphate
what is thin enamel called
hypoplasia
what is remineralsation
teeth naturally repair due to salvia minerals
how much ppm in toothpaste and duraphat
T-1350-1500
D-5000
where is fluoride found
water, tablets, varnish, MW, TP
advantages of fluoride
-prevents reverses decay
-raise bone density
-remineralises enamel
disadvantages of fluoride
-bone loss
-discolouration
-fluorosis (brown)
how to clean protheses
soap, cool water, denture brush, denture cleaner
what is pre and malignant lesions
pre- potentially
mag- progressive and persistent
what is extrinsic and intrinsic and hidden sugar
E- mixed juices, cakes (sucrose, glucose)
I- fruits, veg, milk (calcium, vitamin C)
H- added to products before
Stephens curve pH critical and safe zone
5.5
safe zone- above
what does fizzy carbonated drinks contain
acid, co2, sweetners
acidic foods
vinegar, lime, lemon, orange
what is GORD
gastro-oesophagel reflux stomach acid travels up erodes teeth
what does betel nut do
increases chances of mouth cancer and wears down teeth
what does UV radiation do
increase cancer, burning gums, sensistivy
name 4 lesions
leukoplakia- white not rubbed off
erythroplakia- red patches
non healing ulcer- after 2 weeks
squamous cell carcinoma- raised abnormal growth red white patches
diet lack of calcium, vitamin c, citric and carbonated
calcium- brittle
vitamin c- bleeding gums
citric and carbonated- deacy
what does alcohol cause
trauma, cancer, gum disease, tooth loss, dry mouth
what does smoking cause
cancer, gum disease, patches, ulcers, staining, bad taste
small multiple ulcers is called
herpetiform aphthaus ulcers
what would you provide if someone had 1 missing tooth and other perio mobile teeth
acrylic denture
what happens when caries meets the amelodentinal junction
odontoblast cells react to the bacterial attack by laying down secondary dentine
what is it called when nerve becomes irritated
pulpitis/ reversible
what is it called when caries reaches surroundings of the pulp chamber
irreversible puplitis
pulp death is called
chronic alveolar abscess
what acts as buffering agents in salvia
inorganic ions and minerals
what is erosion
action of extrinsic acid on enamel like lemon, fizzy drinks, vinegar
what conditions can cause erosion
bulimia
reflux
hernia
what is abrasion
scrubbing teeth excessive
what is attrition
loss of enamel from grinding
what is abfraction
loss of tooth at the cervical region
what is perio in young children called
juvenile perio
what attaches gingiva to neck of the tooth
junctional epithelium
stages of perio
-plaque
-produced toxins
-irritated inflamed
-false pockets
-anaerobic bacteria
-calculus
-red swollen true pockets
-toxins attack alveolar bone
what does calculus probe do
sub calculus
non surgical treatment for perio
antimicrobial drugs like gengigel
what is supra and sub
sup- above
sub- below
what scalers for sub
periodontal hoe
ultrasonic
curette
what scalers for supra
sickle/jacquette
push
ultrasonic
what is subacute periocoronitis
infection of gingival flap in wisdom teeth
what is acute herpetic gingivitis
herpes simplex virus ulcers and blisters
what is ANUG
red yellow grey layer on gum membrane
how to treat ANUG
metro
causes of oral cancer
-smoking
-sunlight
-diet
-genetics
-alcohol
what is geographical tongue
loss of tiny hair like structures papillae
what is angular chelitis
salvia collecting in corners drying out
what is pregnancy epulis
gum swelling severe response to debris
what is frictional keratosis
white lesions due to mechanical irritation
factors that effect saliva
-age (slows down rate and quality)
-mumps
-mucocoele (cyst bubble under tongue)
-salivary stone (calcified substance blocks up)
name topical fluorides
-tp
-gels
-varnish
-mw
name systemic fluorides
-water
-tablets
what is enamel fluorosis
white spots on children from too much fluoride
what changes to oral mucosa with age
-skin less elastic and thin
-bone more brittle
-gingival recession
-dry mouth high caries
-darker teeth
what ph is demineralsation
5.5
example of detergent food
apple
what to give pt with infected wisdom gum
hydrogen peroxide
what is the percentage of non fluor and fluor populations
50%
under age 3 ppm
1000
what can you give pt to suppress build up plaque and calc
triclosan with zinc
what food is not relevant to oral cancer
free sugars
