Professional F Application Flashcards
Contraindications of F
laundry list of stuff you know
Treatment of cavitated lesions
Low risk/no risk/ caries free patients living in fluoridated
communities
Situations where post fluoride treatment esthetics is a concern
Patients w/ Ulcerative gingivitis or stomatitis
Patient w/ possible sensitivity or allergy
– Casein
Phosphopeptides come from milk casein and
should not be used with a proven Milk Protein allergy
Dyspnea has occurred in Asthmatic patients (extremely
rare)
Nausea has occurred with extremely sensitive digestive
systems after extensive applications
Topical Fluoride Concentrations: High Concentrations- ‘In Office’
Know ppm F
– 9,040 to 22,5000 ppm fluoride
– Promotes remineralization via CaF
**KNOW THIS
Low Concentrations- @ Home F Concentration
225-5,000 ppm fluoride
*KNOW THIS
Promotes remin via frequent use
How High [c] promotes remin
via CaF
How low [c] promotes remin
frequent use
Types of Fluoride
Acidulated
Phosphate
Fluoride (APF)
■ 2% Neutral
Sodium Fluoride
(NaF)
■ Stannous Fluoride
(SnF2)
■ Silver Diamine
Fluoride (SDF)
Concentration of NaF Varnish
Concentration (highest available)
– 5.0% Neutral Sodium Fluoride
– 22,600 ppm Fl available
How we use NaF based on what FDA says
Off label for caries prevention
Is NaF etching and why or why not
No b/c neutral pH
NaF varnish solifies on contact with
saliva
The varnish of choice for kids under age 4
Neutral NaF Varnish
Knee to Knee technique
how varnish is applied to very young
After perio therapy, what might help reduce sensitivity
Neutral NaF Varnish
Avoid alcohol post NaF varnish application why?
Like dissolves like
apply NaF into proximals?
Yes, especially if you see changes in the radiograph
APF Topical- Gel or Foam Concentration
and for how long?
– 1.23% Acidulated Phosphate Fluoride
– 12,300 ppm available
– 3.5 pH **
4 minute application time
Contraindications for who for APF topical gel or foam
for individuals with extensive porcelain
veneers, porcelain crowns or extensive composite resins
**(pH too > ; possible micro-etching of surface)
How long can one not rinse/brush/eat etc for after APF gel/foam tray?
30 minutes
Should APF foam be filled over the top of the tray?
No-they will swallow it
Neutral NaF topical Foam concentration
and how long is the application and slow uptake?
Is there a caution time out period?
– 2.0% Neutral Sodium Fluoride
– 9040 ppm Fl available
– 7.0 pH
slow uptake-4 min application
still 30 min wait-no brush/eat/rinse etc
If not using varnish… agent of choice for patients with porcelian or composite restorations or those with reduced salivary flow caused by radiation, chemo, medication
Neutral NaF topical foam
Worried about someone swallowing, use APF gel or foam?
Use foam because the dose is lower
****Both ____ and _____ are contraindicated for children under 3! Use what instead???
NaF and APF foams and gels
Use Varnish instead!
*KNOW THIS
Stannous Fluoride-SnF2 Concentration
OTC, rinse, and office
Concentration
– 0.4 % gel (OTC or RX) ; 1,000ppm
– 0.63 % rinse; 3000 ppm (Mix ratio 1:8)
– (8% in-office………)
Mechanism of stannous F and instructions on food and liquid intake
Tin (stannous) component can retard
bacterial metabolism – Forms non- water-soluble stannous layer
No restrictions on food or liquid intake?
Why stannous F is good for perio and plaque reduction
it has antimicrobial properties
Cons of Stannous F
(especially w/ 8%)
– Metallic taste *
– Staining of pellicle *
– Staining of the tooth (?) *
