What are the main differences between equia forte and fuji II LC?
Equia forte: Has better fluoride release and can be placed subgingivally without LC - but has less compressive strength
Fuji II: better compressive strength, better aesthetics and more working time - but can not be cured subgigivally as nice
What are 6 commercial products you could use for a patient with sensativity? How do they work
Sensodyne Rapid relief- stannous fluoride; forms a metal precipitate to occlude dentinal tubules
Sensodyne Daily Care,Sensodyne Pronamel- potassium nitrate, desensitises nerves
Sensodyne Repair and Protect- contains Novamin, occludes dentinal tubules
Oral B Pro Health- contains stannous fluoride which forms a metal precipitate to occlude dentinal tubules
Colgate Pro Relief- contains stannous fluoride which forms a metal precipitate to occlude dentinal tubules
Duraphat/Clinpro- contains resin base and fluoride protector polyurethane; forms insoluble Ca f2 globules after application
What are the two groups of populations that are more susceptible to serious infections? Why?
- Older people - the function of the immune system reduces with age
- Taking immunosuppresants - immune suppresant reduce the function of the immune ysstem
When should you recall the patient after completion of the innital phase of dembridment and provision of at home OHI?
After around 12 weeks in order to give the periodontium the chance to heal
What is supportive periodontal treatment?
It is treatment that plans to maintain already achieved goals with improvement of periodontal health. Patient should come back for assessment every 3-12 months depending on their risk profile )high risk - come every 3 months, low risk - every 12 months)
How can we evaluate risk of periodontal disease progression in the patient?
There dirrent matrix you can use to determine the recall frequency - a common one is the PRA (periodontal risk assessment) and it can be accessed online.
Preio-tools.com seems like the website to go to to find different matrix that may assist you.
Shouldyou probe all the teeth at SPT session
YES of course you should to understand the health of pockets - but you can choose not to do a brand new perio chart unless you find some findings
What are the steps to treatment planning?
1.. Completion of all histories and exams
2. Taking consent for additional testing
3. Diagnosis, presentation of treatment plan and consent
4. Emergency management - aka pain relief
5. Preventativve care/disease control - fluoride, OHI, smoking sessation
6. In chair treatment
7. Close date recall
8. Transition to regular recall
9. Session breakdown
What are the steps to an initial endodontic procedure?
- Consent, LA, rubber dam isolation
- Removal of caries and access to the pulp
- Idenitifcation of the appropriate access using radiographs
- Identification of canals using endo probe
- Using a small size file a few milimeters into a precieved canal in order to confirm that it is actually a canal
- Irrigation with a bent needle for safety
- Flaring of the coronal protion of each canal using Gate-Glidden burs
- Irrigation
- Estimationg of working length of each canal.
- Determination pf correct working length with appropriate file, raiographs and apex locators
- Apical preperation of each canal. Pre-curved files, watch-winding technique performing circumferential filing
- Recapitulate with a size 10 file between each file and irrigate well between each file
- Work up until file 25 -take radiograph to check the master apical file is at an appropriate length
- irrigate and try master gutta percha of the the biggest size possible
- Place medicaments with lentulo spiral
- Resore with cavit and GIC
What are the Kennedy’s classifications of partial edentulous arch?
Class I - bilaterla edentulous areas located posterior to the remaining natural teeth
Class II - A unilateral edentulous area located posterior to the remaning natural teeth
Class III - A unilateral edentulous area with natural teeth remaining both anterior and posteror
Class IV - A single, bilaterla edentulous crossing mid line
What is good guide to stages of periodontits?
- Severity - no tooth loss is Stage I or II, tooth loss of 4 teeth of less Stage III, anything above is Stage 4 - look at radiographic bone loss, if it is upto 15% it is stage I if more stages 2,3,4
- Complexity - If there are major need for rehabilitation - it is stage 4. IF maximum probing depth is above or equal to 5mm it is probs stage II and above
- Extent - localised if less than 30% of teeth are involved
What is a good guide for grades of periodontitis?
- Loss over 5 years - if no than A, if less than 2mm than B if more than 2mm than C
- If a lot of biofilm deposits - probs gare B or C
- If smoking less than 10cig a day grade B if more Grade C
- If diabetes are above 7.0 Grade C if below is Grade B
