26
Q

what is an odontome?

A

a growth in which both epithelial and mesenchymal cells exhibit complete differentiation with the result that functional ameloblasts and odontoblasts form enamel and dentine

27
Q

a) What is EADT and EAT

A
  • EADT is extra alveolar dry time (the time which an avulsed tooth is in air i.e., outside the mouth but not in an appropriate storage medium)
  • EAT is extra alveolar time (the total time the avulsed tooth is outside the mouth i.e., in air and in storage medium)
28
Q

what are some potential storage mediums for an avulsed tooth

A

saliva
normal saline
milk

29
Q

what information would you give someone phoning up about an avulsion

A
  • Tell patient to hold tooth by the crown (explain that this is the part of the tooth you can see when a person smiles, and do not hold it by the root)
  • Rinse under cold water
  • Reimplant immediately (replace in socket and tell child to bite down)
  • Seek urgent dental advice
30
Q

what form of splint is use for subluxation and what is the min time the splint should be in place for?

A

a flexible splint
2 weeks

31
Q

A

2800 ppmF toothpaste

32
Q

what age is it suitable to deliver mouthwash to a paediatric patient?

A

no recommended under age of 6

33
Q

what fluoride dose is toxic and how do you treat specific amounts?

A

toxic dose for 4 y/o child is 75mg

<5mg/kg should give calcium orally (milk) and observe for a few hours

5-15mg/kg should give calcium orally (milk, calcium gluconate, calcium lactate) and admit to hospital

> 15mg/kg should admit to hospital immediately, cardiac monitoring and life support, IV calcium gluconate

34
Q

list potential treatments and what order would you carry them out on a nervous child

A
  1. OHI
  2. fluoride varnish
  3. fissure sealants
  4. hall crown
  5. upper filling no LA
  6. upper filling with LA
  7. lower filling with LA
  8. pulpotomy
  9. extraction
35
Q

before prescribing fluoride mouth rinse what should you check?

A

patient’s age
use of any other fluoride supplements

36
Q

what is the daily strength of fluoride in mouth rinse?

A

225ppmF

37
Q

ED fracture - what is the treatment

A
  • account for fragment
  • bond fragment to tooth or place a ‘composite bandage’ (if the fracture is close to the pulp, line the restoration)
    -take 2 PA radiographs top rule out root fracture/luxation and radiograph lip/cheek to rule out embedded fragment
  • do sensibility testing and evaluate tooth maturity
  • provide a definitive restoration
  • follow up for 6-8 weeks, 6 months and then 1 year
38
Q

what are 4 non radiographic signs and symptoms to monitor over time

A
  • sensibility test
  • colour of tooth
  • sinus
  • mobility
39
Q

what are 4 radiographic signs the tooth is non-vital

A
  • internal and external inflammatory resorption
  • periapical pathology
  • root development has ceased (width and length of canal not growing)
40
Q

how does the nursing bottle caries pattern happen

A

caries which affect the upper anterior and molar teeth
- caused by inappropriate use of feeding cups and bottles

41
Q

a child has carious lower 6s what are you looking for in a radiograph (OPT) for suitable extraction timing

A

furcation of 7s forming
presence of developing premolars and 3rd molars

42
Q

what is the treatment option for upper non carious 6 (when you can lower carious 6s)

A

extraction to compensate for the lack of lower 6s - if not extracted tooth will over erupt

43
Q

2 advantages of extraction of carious 6s at the correct time

A

patient would have caries free dentition
the 7s should drift mesially into the space where the 6 originally was

44
Q

what are 2 disadvantages of extraction of carious 6s

A

loss of a tooth in the permanent dentition
could leave to spacing if the 5s drift distally

45
Q

what are 2 ways of extraction for an anxious child

A

GA
sedation (behavioural management technique)

46
Q

Management of an ED fracture in an 8 year old boy

A
  • Account for the missing fragment
  • Either bond fragment to tooth or place a ‘composite bandage’
  • Take 2 periapical radiographs to rule out luxation injury or root fracture
  • Take radiographs of soft tissue lacerations to ensure no fragments are present
  • Carry out sensibility test
  • Follow up at 6-8 weeks, 6 months and 1 year
47
Q

4 radiographic signs a tooth is non-vital

A

internal inflammatory resorption
external inflammatory resorption
periapical pathology
The cease of root development over time (at follow ups, width and length of canal is not forming at rate it should/in line with contralateral tooth)

48
Q

What are some effects of trauma on permanent successor

A
  • Enamel defects (hypomineralisation or hypoplasia)
  • Abnormal tooth or root morphology
  • Ectopic tooth position
  • Delayed eruption
  • Arrest in tooth formation
  • Odontoma formation
49
Q

what are indications a child’s trauma is non-accidental

A
  • Repeated unexplained injuries
  • The explanation for the injury does not add up
  • bruises in unusual sites (not over bone, behind ears, backs of hands)
  • Burns
50
Q

what are some behaviour management methods for an anxious child

A
  • Positive reinforcement
  • Tell, show and do
  • Acclimatisation
  • Systemic desensitisation
  • Voice control
  • Distraction
  • Imitation of others – role modelling
  • Hypnosis
