Paeds Flashcards
what are the 5 types of crown fracture injuries to teeth?
what are the management options for these 5 types of tooth fracture injuries for PRIMARY teeth?
what are the 7 types of injuries that can occur to the supporting tooth tissues?
what is the management for each of these in PRIMARY dentition?
what are the 8 stages of an examination following a PRIMARY dentition injury?
- MH (3)
- ## examination tests/ special tests
- reassurance
- ensure reduce anxiety of dentist
2.history
- CO history
- MH - extra treatment needed if congenital heart defect, immunosuppression (cancer) or rehumatic fever ALSO tetanus vaccine status?
- legal guardian
- examination
- extra oral (jaw break, mouth opening, CSF[nose/ear], lacerations, haemotoma etc
- intra (soft tissue foreign bodies, bone, occlusion, mobility, transillumination, percussion (dull tone if fracture), tactile probe test, sensibility tests) - diagnosis
- emergancy treatment
- observation (UNLESS - occlusal interferance, risk of aspiration or injestion) - important informaiton (Advice)
- advise on (analgesia, soft tooth brush after every meal, 0.12% chlorhexidine TOPICALLY (2x/day), signs of infection, soft diet/small bits for 10-14days - Further treatment and review
- management of tissue damage - Review
what % chlorhexidine mouthwash is used for adults (12 and over) and which is for children (under 12 but over 6)
0.2% adults and 0.12% for children if stated okat by doctor or dentist
What are the 10 possible effects of PRIMARY tooth trauma on:
i. primary dentition (3)
ii. permanent successor (7)
Primary tooth
1. disolouration
2. discolouration and infection
3. delayed exfoliation
Permanent successor
1. enamel defects (hypomineralisation/hypoplasia)
2. abnormal crown/root morphology (dilaceration)
3. delayed eruption
4. ectopic tooth position
5. arrested development
6. complete failure of tooth forming
7. odontome formation
re: effects of minor PRIMARY tooth trauma on primary dentition
- describe the 3 effects
- what are their treatemnt options
re: effects of PRIMARY tooth trauma on PERMANENT dentition
- describe the 7 effects
- what are their treatemnt options
- why can delayed eruption occur in early loss of a deciduous and how long is normal
- which type of primary tooth trauma tends to cause the most damage to the predecessor tooth
- is there more likley to be damage to the predecessor tooth if the patient is younger or older at the time of primary tooth injury
- intrusion
- younger > chance of issue with predecessor
Mixed dentition stage: trauma to the Permanent teeth:
1. prognosis effected by?
2. emergancy treatment
3. immediate treatment
4. longer term treatment
difference between
1. apexification
2. apexogenesis
- promoting calcification at apex of non vital tooth
- promoting root formation of vital tooth (i.e. only doing cornonal pulpotomy to preserve pulp in canals = continuing root formation (dentine thickness and apex reduction in size) - anything to keep pulp alive
what ages is there a better prognosis for injury to early permanent dentition and why?
before 9-10 years old, as most often incisors and root completion not until these ages
as larger neurovascular bundle at open apex means less likely to have necrosis
treatment in early mixed dentition patient on permanent incisors:
1. enamel fracture
2. dentine-enamel fracture
treatment in early mixed dentition patient on permanent incisors:
- complicated fracture (pulp involved)
* 3 treatment and their reasons for having to be done
- pulp cap (if <24hrs and <1mm)
- partial pulpotomy (>24hrs and >1mm)
- coronal pulpotomy (hyperaemic or necrotic pulp)
Trauma sticker:
- when used
- how long used for
- what it notes (7)
- what the different tooth colours mean
- mixed dentition permanent tooth trauma
- 2 years (senibility tests primarily)
- image
- image
mixed dentition: incisor crown root fracture, treatment options for
1. no pulpal involvement (5)
2. pulpal involvment
when are the follow up visits for paeds trauma patients
what do at these visits
- 6-8 weeks
- 6 months
- 1 year
trauma sticker investigations (7) again and compared
radiogrpahs
* root formation
* pathology
* comparison
* internal inflammatory resorption
^ wrong, actually =
2w, 4w, 8w, 3m, 6m, 1y x5
root treatment for open apex permanent incisors
- options for filling apex
- process carried out
* file length compared to working length
* what used at apex/what this causes
* what are the 4 layers of restoration from apex to coronal definitive rest.
