Exam qs Flashcards
Needlestick with sterile needle?
- clean injury
- place waterproof plaster
- dispose of dirty needle
- report in incident book
3 main evidence based indicators of child being at increased risk of developing caries in next 3 years?
- previous caries experiences
- resident in area of deprivation
- healthcare workers opinion - referral from health visitor
Pulpotomy over direct pulp capping?
direct pulp capping:
- low success rate
- size of exposure does not appear to influence success rate
- extent of pulpal inflammation is hard to assess
- internal resorption is more common when placed over inflamed tissue
- if pulp capping fails, subsequent pulp treatment are likely to fail
What are 6 indications for pulpotomy?
- preservation of tooth is considered necessary
- large proximal carious lesions with involvement of the marginal ridge, where radiograph shows caries extends further than 2/3 of dentine depth
- no radicular pulpitis
- no history of spontaneous pain
- bleeding easily controlled when coronal pulp removed
- no abscess or fistula
What are 6 symptoms of reversible pulpitis?
- sharp, shooting pain
- doesn’t affect sleep
- lasts few seconds - usually goes when stimulus removed
- not ttp
- localised
- exacerbating factors: cold, hot, sweet
What are 8 anatomical risk factors for perio?
- dental crowding
- furcations
- bone defects
- mucosal defects
- root grooves/concavities
- cervical enamel projections
- enamel pearls
- canine fossa
What are 5 acquired local risk factors for perio?
- plaque/calculus
- bleeding on marginal probing
- pocketing 5mm or more are at an increased risk of attachment loss
- poorly controlled/defective restorations
- poor prosthesis
What are 5 signs of dental neglect?
- irregular attendance and repeated missed apps
- failure to complete planned treatment
- returning in pain at repeated intervals
- requiring repeated GA for dental extractions
- dental disease resulting in a significant impact on the child
What are 6 things matrix bands are used for composites?
- restore form and function
- create morphology - marginal ridge
- restore contact points
- limit overhangs
- prevent plaque traps
- good seal
- prevent sticking to adjacent tooth
What are 6 advantages of MTA?
- sets in wet environment
- good sealing properties
- easy to visualise radiographically
- not soluble
- doesn’t interact with other materials
- some antibacterial properties
What are 2 indications for placing a hall crown?
- class 1 non cavitated or cavitated lesions if patient is unable to tolerate conventional treatment
- class 2 lesions cavitated or non cavitated
What are 3 contraindications for hall crowns?
- signs and symptoms of irreversible pulpitis
- clinical or radiographic signs of pulpal exposure or apical pathology
- teeth that would normally be considered unrestorable using conventional methods
Why is caries more difficult to detect on a child?
- broad contact points
- rapid caries progression
- small teeth with relatively large pulp
- irreversible pathological changes before pulp exposure
- early radicular pulp involvement
What would you do for avulsion of deciduous tooth?
- radiograph to confirm avulsion
- do not replant
- review 1 week, 1 month, 2 months, 6 months then 1 year
