PAEDIATRIC TRAUMA II - INJURY TO THE PRIMARY DENTITION Flashcards
1
Q
causes of truma and most common injuryt
A
• Falls and collisions • Non accidental injuries • Prolonged intubation luxation - upper incisors
2
Q
indicators of non accidental injury
A
- Delay in seeking treatment
- Inconsistent history
- Abnormal child reaction and interaction with patient
- Withdraw child
- 50% injuries involved the orofacial region
- History does not match the presentation of the injury
3
Q
examples of non accidently injury
A
burns bite marks freanum tears facial injuries hand marks cigarette burns
4
Q
crown fractures account for
A
4-38% injuries
5
Q
mg of crown fractures
A
1. Infractions • monitor 2. Enamel fractures • Smooth if rough 3. enamel/dentine fractures • grinding/smooth or adhesive restoration 4. Complicated enamel/dentine fractures (involving the pulp) • Pulp cap • Pulpotomy • Pulpectoomy • Extraction
6
Q
crown root fractues
A
2%
usually just extract
7
Q
root fractures
A
3-4 yrs usualy occurs
more apical can leave to heal
exraction can be indicated
8
Q
luxation injuries percentage
A
62-69%
9
Q
subluxation
A
- Tooth tender and mobile
- Not displaced
- May be gingiva haemorrhage
- Supportive advice and review
10
Q
concussion
A
type of subluxation
• Tooth tender
• Not mobile
• Supportive advice (OHI, soft diet for 2 wks, signs to be aware that the tooth is non vital)and review
11
Q
non vital tooth sign
A
• Pain • Abscess • Discolouration • Swelling • Tooth becomes mobile sinus formation EO swelling internal root resorption canal obliteration/sclerosis failure to exfoliate normally
12
Q
intrusion managment
A
- Take xray to confirm severely intruded tooth into the permanent successor
• Leave to reerupt 2-4 months
• Supportive advice and regular clinical and radiographic review
• Or extraction of tooth if displaced into the follicle of the permanent ducessor
13
Q
lateral sublixation tx
A
- if crown displaced palatally can leave providing not in traumatic occlusion
- if crown displaced labially (root will be palatal) reposition or extract
- splinting not necessary for 1y teeth
14
Q
avulsion tx
A
- do not reimplant primary tooth
- may damage permanent successor as pushing root into contact with developing crown
15
Q
how can damage to permanent teeth occur
A
- close relationship of 1 and 2
- disturbance of mineralisation or morphology of developing tooth germ
occurs in 12-69%
