2-7yo preoperational
7-11yo concrete operational

2
Q
why is it recommended that toothbrushing is done by parents until at least 7yo?
A
≤6yo = likely to miss areas and swallow large amounts of toothpastes
3
Q
what percentage of school children are afraid of the dentist and what consequences does this have?
A
16%
avoid attending = deterioration of oral health
often need more complicated and traumatic treatment

6
Q
what is behaviour contagion and how could this affect a child’s dental anxiety?
A
- “tendency of a person to copy certain behaviours of others around them”
- enhances a child’s anxiety (copying parents/family)
7
Q
when does a parent’s presence help the child in a dental appointment?
A
<5yo behave better with parent present (separation anxiety)
8
Q
when would you exclude the parent from a dental appointment?
A
- competing with dentist for child’s attention

22
Q
what is the difference between rigid and flexible splinting and which is preferred?
A
- rigid splint = completely immobilises tooth (≥2 teeth either side, thicker wire), increased risk of ankylosis
- flexible splint preferred = allows some functional movement of teeth (usually 1 tooth either side)
23
Q

A
- easy to place, remove and maintain (often buccal)
- cleansable
- discourages plaque retention

24
Q

A
- permanent teeth usually
- 2 weeks flexible = most traumatic dental injuries
- 4 weeks flexible = associated alveolar bone fractures, apical/mid-1/3 root fractures
- 4 months rigid = cervical 1/3 root fractures
25
describe the procedure to splint a tooth flexibly

6 sandwich the wire with composite, cure
7 place composite balls over ends to ensure no sharp edges, cure
26

33
how does arrest of root development appear radiographically? (3)
- appears shorter than adjacent uninjured teeth
- failure of pulp canal to mature/reduce in size
- may see calcific barrier across apical area (residual vitality)
34

- transient
- inflammatory (infection-related)
- replacement (ankylosis-related)
35
describe inflammatory/infection-related root resorption following dental trauma (cause, process, radiograph, tx)
- usually immature teeth, occurs very quickly
- caused by non-vital pulp with severe traumatic injuries and PDL injury
- commonly external RR
- necrosed pulp, damaged cementum --> osteoclast activity on root surface
- seen radiographically from 3 weeks = punched out resorption
- propagated by necrotic pulp so early extirpation and calcium hydroxide dressing helps
36
describe replacement root resorption/ankylosis following dental trauma (process, clinical, radiograph, management)
- aetiology poorly understood
- damage to root surface --> replacement with bone
- tooth may be lost in 3-7 years in younger patients (fast bone turnover)
- high "metallic" note when tapped, no physiological movement
- loss of radiographic PDL space from 2-12months
- often decoronated to maintain alveolar bone whilst preventing gingival margin discrepancy
37

STILL HAVE CONCERNS:
3 provide urgent dental care
4 talk to child and parents and explain concerns, inform of intentions to refer and seek consent to share info
5 refer for medical examination if needed, keep full clinical record
6 refer to children's services, following up in writing within 48 hours

3 child protection referral
- implemented according to level of concern
269
describe the "was not brought" pathway
1 - reception calls parent within 24 hours for reason for WNB and offer new appointment, also offer discussion about any worries
2a - phone contact success = send WNB1 letter home and document
2b - phone contact failure = send WNB2 letter home, document and wait
- parent contacts = step 1 and documentation
- parent fails to contact within 3 weeks = clinician informed and risk assessment (sharing of information, contact GP) and decide if further action is required, document
270
give some barriers to the management of dental disease in medically compromised children (3)

281
how does dental treatment planning vary for children with CV disorders? (5)
- aggressive prevention (diet, F-, FS,OHI) with regular clinical and radiographic monitoring

- no antibiotic cover for routine procedures, consider cover if chronic infection
- more radical treatment planning due to risk of chronic infections and IE
- do not conduct routine dental tx until symptomatic cardiac disease is thoroughly investigated
282
how may avulsed permanent tooth management differ for children with CV disorders? (2)
