Recognition, Re-orientation, Remineralisation, Repair and Review
What is the high fluoride concentration ?
22,600 ppm
How much fluoride do you give patients aged 2-5 ?
0.25ml
How much fluoride do you give for patients aged 6 and over ?
0.4ml
When is fluoride application contraindicated for?
Allergy to colophony, ulcerative gingivitis/ stomatitis and patients that have been hospitalised due to sever asthma or allergy
What do you need for topical fluoride placement ?
mirror
3 in 1
cotton wool rolls
microbrush
dispensing pad
topical fluoride varnish
6 stages of topical fluoride placement
- Inspect tooth with mirror under direct or indirect vision
- If plaque/food particles are present - clean with a toothbrush
- Isolate teeth and achieve moisture control
- Use a micro-brush to apply fluoride varnish to the contact points
- Apply fluoride to occlusal surfaces next
- Advise patient to avoid eating drinking for 30 mins after and avoid brushing for at least 4 hours
Materials for GI
- Cotton wool rolls/ dry guard
- Toothbrush
- Petroleum jelly
- Probe or excavator (as required)
- Ball ended probe and mirror
- flat plastic
- glass ionomer
- dental floss
articulating paper
GI procedure
- Inspect under direct or indirect vision – clean, dry tooth.
- If debris is present, remove with toothbrush or a blunt instrument e.g., ball ended probe - buccal lingual orientation
- Isolate tooth and achieve moisture control – cotton wool rolls/dry guard
- Technique 1 – blunt ended instrument e.g., flat plastic, ball ended probe or directly if using capsule
- Dry tooth
- Apply GI to tip of flat plastic
- Apply GI to fissure pattern (not extend up sides of cusps more than 1mm)
- Shape using flat plastic
- Place forefinger over tooth. Ensure occlusal surface is covered.
Technique 2
- Dry tooth
- Place forefinger on tooth and press firmly - Keep finger firmly placed over sealant for 2 minutes
- Remove finger – keep moisture control
- Place petroleum jelly on occlusal surface (barrier against moisture)
- Floss adjacent contact points
- Check occlusion with articulating paper
- Advise pt to not eat for at least 1 hour
Resin fissure sealant materials
- Cotton wool rolls/ dry guard
- Probe or excavator (as required)
- Ball ended probe and mirror
- Flat plastic or blunt ended instrument
- Resin fissure sealant
- Dental floss
- Articulating paper
- 37% phosphoric acid etch
Curing light and shield
Fissure sealant procedure
- Inspect tooth under direct/indirect vision
- Remove debris with toothbrush or blunt ended probe – buccal lingual orientation
- Isolate tooth and achieve moisture control
- Apply acid etch to tooth – ensure tip is securely on and syringe must be in plastic barrier - leave for 20-30 secs
- Remove etch using suction
- Rinse thoroughly
- Dry tooth – maintain moisture control
- Apply resin sealant – load onto a instrument
- Light cure
- Use sharp examination prone to examine circumference of sealant
- Check occlusion with articulating paper and adjust if necessary
- Ask pt to bite and ask they how it feels
- Floss adjacent contact points
Why do we use topical fluoride placement ?
prevention or management of caries
Why do we use GI ?
Seal pits and fissures for caries prevention and a t as temporary sealants
When is GI sealant useful ?
Child not cooperative or difficulty with moisture control
Why do we use resin fissure sealant ?
prevention - to seal pits and occlusal fissures
treatment - pits and fissures carious lesions can be arrested by sealing them under restoration to deprive carious biofilm of nutrients
