Child and Adolescent Radiology Flashcards
Should we take routine radigraphs based on the time between last examinations
No this is not supportable and the intervals between radiographic examinations should be reassessed for each new period as individuals can move in and out of caries risk categories over time
How frequently should bite wing radiographs be taken in child patients with mixed dentition depending on their caries risk categories (FGDP guidelines)
High caries risk - 6 months
Moderate caries risk - 12months
Low caries risk - 12-18 months
How frequently should bite wing radiographs be taken in child patients with permanent dentition depending on their caries risk categories (FGDP guidelines)
High caries risk - 6 months
Moderate caries risk - 12 months
Low caries risk - 24 months
What are the 3 categories of oro-dental trauma
- Crown Fracture
- Root Fracture
- Luxation injuries
What categories of luxation injuries are there
Concussion Subluxation Intrusion Extrusion Lateral extrusion Avulsion
What is a concussion oro-dental trauma injury
When the tooth is not loose and not displaced in the socket at all
What is a subluxation oro-dental trauma injury
When there is an incomplete/partial dislocation of the tooth
What is an intrusion oro-dental trauma injury
This is an inward displacement of the tooth into the socket
What is an extrusion oro-dental trauma injury
This is the movement of the tooth out of the socket beyond the natural occlusal plane
What is an avulsion oro-dental trauma injury
This is the displacement of the tooth from its alveolar socket completely
When should dental radiographs be taken for management of minor tooth trauma
- Need an initial baseline radiograph
- Follow ups should be taken 6 months after treatment
- And then annually until root formation is complete
If tooth trauma in a child affects the pulp what treatments can be done for vital pulp
Pulpotomy or Pulpectomy
If tooth trauma in a child affects the pulp what treatments can be done for non-vital pulp
Root Canal Treatment
Is a radiograph needed for vital pulp procedures
Yes
What radiographs are needed for root canal treatment
- Pre-operative radiograph
- Workling length radiograph
- Mid fill radiogrpah
- Post operative radiograph
- Follow up radiograph (1 year)
Why should you take a mid fill radiograph for root canal treatment
If you are in doubt about the integrity of the apical constriction
Why do we need to take x rays in some periodontal disease cases
This disease can affect bone destruction and there may be systemic diseases affecting the tooth structure
What depth of pocket in periodontal disease gives a score of 3
3.5-5.5mm
If your BPE score is 3 what radiographs would you need
Horizontal bitewings
Supplemented with/out selected anterior peri-apicals
What depth of pocket in periodontal disease gives you a score of 4
5.5+ mm.
If your BPE score is 4 what radiographs might you need
Vertical bitewings
Supplemented with/out selected anterior peri-apicals
If you have generalised pocketing in your periodontal disease what radiographs can you have
Panoramic Radiographs supplemented with/out peri-apicals
OR
A complete series of peri-apical radiographs
Why do we need radiographs in orthodontic treatments
Problems like impacted teeth, spacing/crowding and malocclusion
What radiographs are needed for orthodontic treatments
Panoramic and Lateral cephalograms
What are some less common problems for taking radiographs in children
Cysts
Tumours
Bony lesions
What does a cyst look like on a radiograph
Shown in the alveolar bone around a root and will appear darker than the surrounding tissue
What is a Cone beam CT used for
In adolescent patient’s teeth looking for wisdom teeth, implant planning, unerupted teeth etc.
