2016 ppq Flashcards
two organisms involved in angular cheilitis?
Condition that would be seen orally?
s.aureus
C.albican
denture induced stomatitis
hyperplastic candidiasis
sample to collect for angular cheilitis?
swab
What would you use if could not/ no sample for angular cheilitis?
Miconazole
antibacterial and antifungal activity
against candida and staphylocci
Two example of immunocompromised and gastric bleeding disease. Aetiology?
immunocompromised:
- HIV
- Diabetes
- Leukaemia
immunosuppression=
= allows opportunistic pathogen to cause the disease
= reduced immune function .:. reduced ability to fight off infection
bleeding: -Crohn's -Ulcerative Colitis -peptic ulcer = loss of immune cells in blood =lack of absorption .:>malnutrition
Instructions to give pt on denture hygiene?
remove at night
soak in alkaline peroxide for 20 minutes then in water
Types of fluoride delivery for a 13 year old
fluoride varnish 22600
fluoride toothpaste 1450
fluoride mouthwash 225
fluoride tablets 1mg
For pt with orthodontic decal what else could you give?
diet advice and OHI
8 risks of ortho tx with fixed appliance?
root resorption relapse failure enamel wear recession soft tissue trauma loss of vitality allergy
4 ways to gain haemostasis
damp gauze and pressure LA with vasoconstrictor surgicel and sutures diathermy artery forceps
term for delayed onset of bleeding
reactionary up to 48 hours
up to a week is called secondary
- secondary generally caused by infection causing breakdown of clot
2 congenital and 2 acquired bleeding disorders
Haemophilia and von Willebrands disease
drug therapy and alcohol liver disease
When do you have to monitor INR for before procedure?
ideally no more than 24 hours before the procedure.
if a stable INR, checking the INR no more than 72 hours before is acceptable.
How many occlusal units is 2 occluding premolars and one pair of occluding molars?
3
WHat skeletal classes are contraindicated with SDA?
why?
severe class 2 class 3
less likely for there to be occluding pairs in a severe malocclusion
Why is periodontal disease a contraindication for SDA? 3 reasons
poor prognosis of teeth
drifting of teeth under occlusal load
loss of alveolar bone leading to compromised denture bearing area in long term
What metal is used for casting an adhesive bridge?
why?
CoCr
strong, hard, high young’s modulus
What is the 5 year survival rate for resin retained bridge?
~80%
11 ed fracture, >1 mm >24 hours. immediate mgmt?
- –account for missing tooth fragments
- –radiograph to check for any root displacement or fracture
- –LA, dam
- –reposition tooth if any displacement
- –removal coronal pulp until into healthy pulp
- –haemostasis cotton wool pledget soaked in saline
- –if no haemostasis remove pulp tissue until haemostasis can be achieved
- –direct pulp cap placed and sealed using adhesive restoration
why is subalveolar fracture poor prognosis?
- lack of tooth tissue to support a restoration
- difficulty of isolation and moisture control for any treatment
- difficulty placing subgingival crown margins
- cannot clamp tooth to carry out endo
denture induced stomatitis. features of palatal tissues?
erythematous
papillary hyperplasia
first line of tx denture induced stomatitis?
second line?
denture hygiene advice
tissue conditioner
CHX MW
2) systemic antifungals- fluconazole, itraconazole
topical- miconazole, nystatin
lab instructions for special tray manufacture?
please pour primary impressions in 50/50 stone/plaster and construct special trays in light cure acrylic, non perforated, upper with 2mm wax spacer and lower with 1mm space with intraoral handles and finger rests in premolar region, please ensure muscle attachments are relieved
sensitivity to sweet. pulpal diagnosis?
reversible pulpitis
Metal used in wing of resin retained bridge?
CoCr
Four faults that can occur to cause RRB to debond?
poor moisture control during cementation
unfavourable occlusion
poor enamel quality on abutment
inadequate coverage of abutment
what design could you do for RRB to minimise risk of debond?
pick tooth with large bonding area for abutment
cantilever design for anterior sextant
3 questions to ask mum of child who has swallowed toothpaset
