Review of Endodontic Principles Flashcards
(50 cards)
What is endodontoogy?
Endodontology is concerned with the study of the form, function and health of, injuries to and diseases of the dental pulp and periradicular region, their prevention and treatment; the principal disease being apical periodontitis, caused by infection
What causes endodontic disease?
Bacteria
Who presented he research to prove tat bacteria causes Endodontic diseases
Kakehashi
What are the three key features needed for disease to occur?
- Micro organisms
- Host
- Time
Why is studying endodontic microbiology important?
Can hep identity which bacteria is playing a key role in progression of the disease
This canhelpwiith treatment planning as we can get rid of the harmful bacteria
Do we only remove/kill the harmful bacteria when carrying out root Canal treatment?
No we try and remove all the bacteria in the root canal
Is the distribution of bacteria in the root canal even?
No
Theres more aerobic bacteria found near the apex of the canal
More bacteria in general is found in the coronal third as that is where the most nutrients are found
Name the 2 different types of bacteria systems found in eat root canal
- Planktonic
2. Bioflm
What are planktonic bacteria|?
They are free floating
Which of the 2 bacterial systems is easier to remove?
Planktonic bacteria
What is a plaque biofilm?
An aggregation of micro organisms growing a solid substrate
Describe plaque biofilms found in the root canal
They are a complex community made-up of a lot of different bacteria
Their xtra cellular matrix is made up of thick dense polymeric substances which is hard to remove
How are biofilms resistance to eradication
1, Physical barrier- poor anti microbial penetration and sequester cells from host immune cells
- It is difficult to remove mechanically
- In a biofilm there is a transfer of genes which can increase virulence factors and resistance
What is Endodontology clinically?
It is the diagnosis and management of:
- Pulpal disease
- Periapical disease
What is the biggest problem we encounter when trying to diagnose endodontic disease
We are reliant on patients description of the symptoms (we can’t seethe disease until we start treatment)
Theres a poor correlation between symptoms and histological status of ethnic pulp
Which nemonic do we use to help us diagnose endodontic disease
SOCRATES
Go through SOCRATES
Site Onset Characteristic Radiation Alleviating factors Time Exacerbating factors Severity
After taking a pain history what else can we use to help us reach a diagnosis?
- We can use sensitivity tests and radiographs
2. Also look at soft tissues looking for palpations, swelling and sinus
What is the problem with using radiographs to diagnose Endodontic disease?
Until the critical plate has been lost the lesion may not be visible with conventional radiography
What new technique has Coe out to overcome the problem of a tick cortical bone obstructing our view of a lesion
Contemporary CBCT imaging technology can overcome the problem as it takes 75microns slices of the entire area
What are the problems associated with CBCT
It is a higher dose than normal radiographs so must consider dose and benefits
When looking at the tooth before reaching a diagnosis what do we look at?
Palpation
Percussion (GENTLE)
Mobility
What problems can arise wen we do special sensitivity tests?
Need to be wary of multi rooted test as they can give false positives
What do we have to put-on before starting rot canal treatment
