Paediatrics Flashcards
what is the most common injury in the primary dentition
luxation injury
what is the most common injury in the permanent dentition
uncomplicated crown fracture
When a child presents to you with a traumatic injury, what are the 7 steps you should take in treatment
- Reassurance
- Take detailed history
- Examination
- Diagnosis
- Emergency treatment
- Important information for parents
- Further treatment and review
why is it important to reassure patients
trauma may be the reason for the child’s first visit to dentist and can be upsetting for both child and parent. It was not a planned visit.
what questions would you ask when taking a trauma history
- When did the injury occur - time interval between injury and treatment can significantly influence prognosis of some injuries
- Where did the injury occur - this may indicate need for tetanus
- How did the injury occur - the nature can yield information on type of injury suspected and discrepancy may raise suspicion of abuse
- Are there any other symptoms or injuries - concussion, headache, vomiting, amnesia may require investigation at hospital for brain damage
- Are there any lost Fragment/teeth - if cannot be accounted for, a chest radiograph should be obtained
when taking a medical history following trauma, what should you pay particular attention to
- Congenital heart disease - may influence treatment which would be offered if an infection risk must be minimised, liaise with cardiologists
- History of rheumatic fever or immunosuppression
- Bleeding disorders - haematology team can be contacted
- allergies - may need to give antibiotics
- Tetanus immunisation status
when taking a dental history following trauma, what should you ask
- Previous trauma - explain baseline clinical and radiographic findings and repeated episodes can raise concerns regarding abuse
- Treatment experience - how does child usually cope at dentist
- Legal guardian/child attitude to treatment - are they keen/is attending easy for them
When carrying out an extra-oral exam following trauma, what should you look for
- lacerations (bruising and swelling as well)
- haematoma
- haemorrhage/ CSF
- subconjunctival haemorrhage
- bony step deformities
- mouth opening
when carrying out an intra-oral exam following trauma, what should you look for
- soft tissues - lacerations, haematomas and swelling should be recorded and lacerations examined for tooth fragments/foreign materials
- Alveolar bone - assess for evidence of fracture
- Occlusion - does patient feel bite is normal
- Teeth - charted and any dental injury recorded
what can tooth mobility indicate
- tooth displacement
- root fracture
- alveolar bone fracture
what six things are recorded on a trauma stamp
- mobility
- colour
- TTP
- Sinus
- Percussion note
- Radiograph
what radiographs are used to diagnose a root fracture
- two periapical radiographs
After a traumatic injury in the initial emergency treatment, what homecare should you recommend to parents
- analgesia - ibuprofen and/or paracetamol
- soft diet for 10-14 days - cut things into small pieces and chew with molars
- brush teeth with a soft toothbrush after every meal
- topical chlorhexidine gluconate 0.12% mouthrinse twice a day for 1 week
- warn regarding signs of infection
what is a concussion injury
Concussion injury to the tooth supporting structures without increased mobility, displacement of tooth or gingival bleeding. There is pain on percussion and sensibility tests may initially be negative
what is a subluxation injury
subluxation is when a traumatic injury has occurred to the periodontal tissues leading to increased mobility, gingival bleeding but no displacement
what is a lateral luxation injury
a lateral luxation injury is displacement of a tooth other than axially (palatal, lingual or labial). Displacement is accompanied by communication or fracture of either the labial or palatal/lingual bone. The PDL has suffered both tearing and crushing injuries
what is an intrusion injury
an intrusion injury is when the tooth has been driven into the alveolar process due to an axially directed impact. The tooth is usually displaced through the labial bone plate but can impinge on the permanent tooth bud. Crushing injury to PDL
what is an extrusion injury
an extrusion injury is when the tooth is either partially or completely separation from the PDL resulting in displacement of the tooth out of the socket. This is a tearing injury to the PDL
what is an avulsion injury
an avulsion injury is when the tooth is removed completely from the socket. Location of missing tooth should be determined during history and exam
how would you treat an enamel fracture to the primary dentition
- smooth sharp edges with a soft flex disc
how would you treat an enamel-dentine fracture to the primary dentition
- cover exposed dentine with either GI or composite
- restore lost tooth structure with composite
- follow up 3-4 weeks
Radiographic findings will detect no abnormalities
how would you treat a complicated crown fracture to the primary dentition
- partial pulpotomy - inflamed part of coronal pulp removed and non setting CaOH placed over pulp with a thin layer of GI on top restored with composite
- Extract
Follow up
- 1 week clinical
- 6-8 weeks clinical and radiographic
- 1 year clinical and radiographic
Looking for - continuing root development in immature teeth and a hard tissue barrier
how would you manage a crown root fracture in the primary dentition
- remove loose fragment and determine if crown can be restored
- if restorable - pulpotomy/ cover exposed dentine with GI
- if unrestorable - extract loose fragments
Follow up
- 1 week clinically
- 6-8 weeks clinical and radiographically
- 1 year clinically
Check for signs of apical periodontitis, no continuing root development (these are poor outcomes)
how would you manage a root fracture in primary dentition
- coronal fragment not displaced - no treatment
- coronal fragment displaced but not excessively mobile - leave to spontaneously reposition even if some occlusal interference
- coronal fragment displaced and mobile - either extract loose fragment or reposition loose fragment and splint
how would you manage a concussion injury in primary dentition
no treatment, tooth should be reviewed 1 week and 6-8 weeks clinically
Favourable outcome - continuing root development in immature teeth
how would you manage a subluxation injury in the primary dentition
no treatment - observe and review
Follow up
- 1 week clinical
- 6-8 weeks clinical
how would you manage a lateral luxation in the primary dentition
- allow to reposition spontaneously
- if displacement causes occlusal interference, tooth can be gently repositioned by combined labial and palatal pressure under local anaesthetic
- if displacement is severe, extract (favourable) or reposition and splint for 4 weeks
follow up
- 1 week clinical
- 2-3 weeks clinical
- 6-8 weeks clinical and radiographically
- 1 year clinical and radiographically
how would you manage an intrusion injury to the primary dentition
- allow tooth to spontaneously reposition itself if the apex is displaced through labial plate
- extract if apex displaced into developing tooth germ
follow up
- 1 week clinical
- 2-3 weeks clinical and radiographically
- 6-8 weeks clinical
- 6 months clinical and radiographically
- 1 year clinical and radiographically
the apical tip of an intruded tooth can be seen and the tooth appears short compared to contralateral tooth radiographically, what does this mean
the apex has displaced towards/through the labial bone plate
the apex of intruded tooth cannot be visualised and tooth appears elongated compared to contralateral radiographically, what does this mean
apex has displaced towards permanent tooth germ
how would you manage an extrusion injury to the primary dentition
- not interfering with occlusion - spontaneous repositioning
- excessive mobility or extruded more than 3mm - extract
how would you manage avulsion in primary dentition
- radiograph to confirm avulsion
- do not replant
- follow up
1 week clinically
6 months clinical and radiographically
1 year and every year until eruption of permanent clinical and radiographically
