Further Treatment Planning Flashcards
What did the dundee cariology study find in terms of statistical significance?
The relationship between the observation of a clear band of dentine is statistically considered to be HIGHLY SIGNIFICANT.
What % of hall crowns succeeded in the DDH study with a clear band of dentine?
97.3%
What did the dundee cariology study find in terms of NOT statistical significance?
The relationship between depth of carious lesion and outcome is statistically considered to be NOT SIGNIFICANT (as long as there is a clear band of dentine).
When will occlusal reequilibration occur after the placement of a hall crown?
4-6 weeks.
Why can you not place hall crowns on opposing teeth?
Mouth will not be able to re equilibrate adequately which can lead to THEORETICAL TMJ PAIN + UNCOMFORTABLE PATIENT.
Can you place multiple crowns in the same visit?
CAN PLACE MULTIPLE CROWNS IN THE SAME VISIT BUT THEY MUST NOT BE ADJACENT (NEIGHBORS) OR OCCLUDE ON TOP OF EACH OTHER.
What is SDF?
clear, odourless, metallic-taste liquid that will stain most oxidizable surfaces black upon exposure to light due to the formation of a silver oxide layer
What does S in SDF contain and what are its 3 effects?
- Effects on bacteria.- Hydroxyapatite doping- Collagen degradation inhibition
What does the F in SDF do (2 effects)?
- Mineral formation (fluoroapatite - reduced degradation of hard tissues in acid). - Collagen degradation inhibition.
What can you put after applying SDF?
Potassium iodide. Supposed to prevent the blackening effect by binding the free silver ions yet this DOESNT OCCUR.
Indications for SDF (6)
- Patients at high risk of developing caries (xerostomia or severe early childhood caries).- Pre-cooperative children (very young children).- Treatment challenged by behavioral or medical conditions.- Patients with several carious lesions that may not all be treated in one visit.- Difficult to treat dental carious lesions (ex. root caries).- Patients without access to dental care.
Contraindications for SDF?
- Silver allergy- Pain - Irreversible pulpitis or periapical periodontitis→Spontaneous, severe, constant pain or wakening child at night- Infection→Swelling of soft tissues, abscess or fistula- Patient refusing treatment or unable to cope- Unable to isolate tooth & maintain control over oral environment
4 things you must do before placing SDF
- Will have already have agreed to the treatment plan- Ensure they know and the parent knows that the lesion will go dark/ black- Ensure the child has safety glasses on and an apron- Warn your nurse it will stain anything it touches!
4 steps to the placement of SDF?
- Isolation with cotton rolls, dry tooth with air2. Dispense a minimal amount of SDF into a dish3. Using a micro-brush, apply the SDF solution on to the carious lesion and agitate for 1 minute4. Remove excess SDF following procedure completion
What was the % acceptability of SDF in children who did not require GA for treatment?
27% (vs 73% unacceptable).
