Q

Describe how pregnancy might affect endo treatment?

A
  • Is NOT a contradiction
  • In the first trimester would do emergency intervention only

-pain and infection managed in collaboration with obstetrician/physician

Note: unborn child is at more risk if the infection is not treated

Q

What considerations/changes would you make for someone with a CVS with regards to endo?

A
  • an MI within the past 6 months is a contraindication (delay treatment until this is out of the 6m window)
  • Emergency treatment should be provided in consultation with the P’s cardiologist

-Stress reduction protocols should be put in place (short appointments, sedation, pain and anxiety control)

Q

What would you need to do and consider with endo treatment in a cancer patient?

A
  • thorough history essential
  • think about cancer treatment as chemotherapy and radiotherapy to the head and neck region can compromise healing
  • Consult with the oncologist
  • need to try and minimise infection risk with cancer patient

Q

How is an endo infection and diabetes link?

A

An acute endodontic infection can compromise even a well controlled diabetic; so all diabetes patients must be monitored
P’s with uncontrolled diabetes must be monitors

Q

How might diabetes affect the prognosis for endo treatment?

A

They have poorer healing so need to consider this and mention it in the discussions about prognosis

Q

For patients on bisphosphates, what are the implications on endo therapy?

A
  • IV greater risk
  • Preventative care important
  • non-surgical endodontic treatment of teeth that might otherwise be extracted is better
  • Use entire health team when developing treatment plans for these patients

Q

What allergies might have an impact/need adjustments made to endo therapy?

A

Latex allergy = use rubber dam

Gutta Percha not a risk as non-cross-reactive

Q

What periodontal considerations should there be when deciding on endo treatment?

A
  • BPE and 6 point pocket for tooth of interest needed
  • if poor prognosis may require extraction

-might want to do perio treatment then assess then endo or opposite way round

Q

What restorative considerations should be made with regards to endo treatment?

A

Is the tooth restorable?:

  • sub-osseous caries
  • poor root/crown ratio
  • misalignment of teeth (better to extract)
  • Presence of pre-existing full coverage restorations (is the tooth already severely compromised?)
17
Q

What can you do if you are unsure about the tooth’s restorability?

A

Deconstruct - remove all previous restorations and decay so the extent of healthy tooth structure can be determined

DONT CARRY OUT ENDO if cant restore a tooth with a high degree of certainty

18
Q

What kind of mirror is used in endo?

A

front surface mirrors (less distortion)

19
Q

What are some other factors that can complicate endo treatment?

A
  • calcifications, dilacerations and resorption
  • inability to isolate a tooth
  • unusual anatomy
  • ledges and perforations
  • posts
  • separated instruments
20
Q

What are calcifications in the tooth?

A

Parts of the tooth that have calcified which can mean loss of the pulp chamber (wont be able to find it)

21
Q

Calcifications of the tooth can make orthograde management very difficult. How might a calcified tooth requiring root treatment be maneged?

A

Surgical approach may be required

22
Q

How can you tell if resorption is internal or external?

A

By its radiographic appearance

External appears to be superimposed on the canal, whereas internal resorption appears to be continuous with the canal

23
Q

What is the gold standard for intra-oral radiographs when determining the anatomy of a tooth and root structure?

A

2 views to allow us to assess the root canals and divisions

24
Q

When might CBCT radiographs be used for endo?

A

for more complex cases where lower dose radiographs doesn’t provide adequate diagnostic info

25
Q

What are some anatomical things that radiographs might show that you should consider?

A
  • Large open apices
  • C-shaepd anatomy
  • developmental anomalies
  • ledges on restorations
  • previous endo treatment
  • previous perforations
  • separated instruments
26
Q

What are the options for treatment in endo?

A
  • No active treatment with review
  • Extraction
  • Orthograde root canal treatment
  • Surgical endodontics
27
Q

A common reason for claims is ‘poor management, including failure to take radiographs or refer appropriately’. What should you do in order to avoid this?

A
  • Make sure to self-assess yourself. Do you have the skills and experience to carry out this treatment?
  • Know when to treat and when to refer
28
Q

When are you at greater risk of perforating a tooth?

A

If there is a big root curvature

29
Q

When are you at greater risk of causing instrument separation?

A

Curved and narrow canals

30
Q

Pain is expected after endo treatment. What post op instructions would you give to patients?

A

Take ibruprofen to delay the onset and decrease the severity of the pain
