1

Purpose of flouride. What does it do?

Inhibits demineralization, enhances remineralization, and inhibits plaque
formation

2

Optimum range of fluoride in drinking water (ppm)

the optimum range of fluoride
concentration of 0.7-1.2 ppm

4

Dentifrices
Mouth Rinses are what type of fluoride products
Rx Dentifrices & Gel
Rx Mouth Rinses

Self-applied nonprescription products

5

INDICATIONS FOR PRESCRIPTION
FLUORIDE USE

• Moderate/high caries risk determined by risk
assessment • Caries or white spot lesions/ demineralization • Dental hypersensitivity • Exposed root surfaces

6

PROFESSIONALLY APPLIED PRESCRIPTION PRODUCTS are?

-Sodium Fluoride (NaF)
-Sodium Neutral Fluoride (NaF) Foam
-Acidulated Phosphate Fluoride foam

7

Acute ingestion of fluoroide

Rapid ingested over short period of time - RARE

8

Chronic ingestion of fluoride

long term ingestion that exceed the approved therapetuic levels - Dental fluorosis-tooth development
- Skeletal Fluorosis

9

What are the percentages of the professionally applied prescription fluorides below?
1. NaF varnish/Sodium Fluoride
2. NaF gel or foam/Sodium Neutral Fluoride
3. APF gel or foam /Acidulated Phosphate Fluoride

1. 5% NaF varnish
2. 2% NaF gel or foam
3. 1.23% APF gel or foam

10

Sodoium Fluoride varnish is FDA approved for and off label use is for

FDA approved for dentinal
hypersensitivity…off label use is for
caries prevention

11

CONTRAINDICATIONS for VOCO fluoride varnish is

colophony rosin - solid form of resin obtained from pines

12

APF/ Acidulated phosphate fluoride gel or foam contraindication!

Contraindication: potential for etching; not to be used for patients w/ porcelain & composite restorations, sealants, titanium implants, sensitivity

13

How can people take fluoride systemically

take fluoride drops or tablets

14

• Emergency protocol for fluoride ingestion

• Induce vomiting
• Second person assist as needed- Call 911
• Administer binding liquid- milk, milk of magnesium,
limewater (if pt isn’t vomiting) • Additional therapy indicated at ER

15

Contraindications for Sealing

Wide fossa – self cleaning
Low caries risk
Good dietary habits
Restorations present
Decayed teeth (evaluate radiographically for interproximal decay)

16

Indications for Sealant Application

Deep pits and narrow fissures on occlusal surfaces
Xerostomia
Orthodontics
Recently erupted teeth
Incipient caries
Snacking >3X/day
Teeth free of interproximal caries
Elevated risk for dental caries
Total prevention program
Heavy plaque
Infrequent preventive care
Head and neck radiation

17

Factor Affecting Penetration & Bonding

Dry field- Saliva occludes porosities and inhibits bonding. Re-etch with acid 10-20 seconds following saliva contamination.

Free from oils and flavoring-pumice.

18

proper sequence for sealant application (general)- don’t worry about how long to etch or cure.

Clean/ toothbrush or polish
Isolate
Dry
Etch-period of time
Rinse-period of time
Isolate/Dry
Sealant material
Cure or not depending

20

Contraindications to essential selective polishing

Medications?
Inflammation
primary teeth
cementum
restorations

21

Angle rubber polish cup to __at gingival margin. Use __ pressure

flare
moderate

22

Polishing: Modified pen grasp- rest HP in ___
between thumb and index finger

1. V
2. between index nuckle 1

V

23

Contraindications to essential selective polishing

Medications?
Inflammation
primary teeth
cementum
restorations
-Decalcification, hypocalcification,
demineralization,
rampant caries
Immediately following nonsurgical
periodontal therapy- gingival treatment
and or scaling and root planing
Inflamed gingiva:enlarged, spongy, or
bleeds easy

24

Polishing: Employ “___ and ___” motion working from
gingival 1/3 to incisal/occlusal 1/3

pat and sweep

25

2 types of powered instrumentation and cycles per second for each

Sonic: Low frequency 3,000-8,000 cycles/second

Ultrasonic: frequency of 18,000-
45,000 cycles/second

26

2 Subtypes of ultrasonics and how they differ

- Piezoelectric Electrical energy activates ceramic crystals within the handpiece to make the tip vibrate
- Magnetostrictive Electronic energy is transferred to metal stacks or to a ferrous rod.

27

Cavitation, fluid lavage, amplitude, frequency

Cavitation- Tiny bubbles formed by water stream. Bubbles collapse, which produces
shock waves that may alter or destroy bacterial
cell walls.

Levage: flush
out bacteria from beneath the gingival
margin

Amplitude- How far the instrument tip moves back and forth during one cycle. (length of stroke)

Frequency- How many times the tip vibrates per second (kHz)

28

Limitations for powered instrumentation

Disadvantages
less tactile senstiitivty
water control
production of aerosals
medical contraindications
potential occupational hazard(noise and vibrations)

29

Slim vs standard working ends- when and where they are used- appropriate power settings for each

Slim : Light to moderate calculus
Improved for subgingival access due to 30% thinner

Standard: Moderate to heavy calculus
Thicker inserts with larger tips, specifically designed for efficient removal of heavier deposits

30

Contraindications to ultrasonics

-Communicable diseases- Aerosol production allows for dissemination of bacterial and viral infections; Hepatitis, TB, respiratory infections.

-High susceptibility to infection- Immunosuppressed patient due to disease or chemotherapy, uncontrolled diabetics, patients with organ transplants or chronic, debilitating medical conditions.

-Respiratory risk- Emphysema, cystic fibrosis, asthma, cardiac disease with secondary pulmonary disease, pneumonia, breathing problems.

-Unshielded cardiac pacemaker- Piezoelectric ok- only concern with magnetostrictive; may need physician consult to verify type of pacemaker present.

-Dysphagia (difficulty swallowing) or prone to gagging- MS; ALS; Muscular dystrophy, paralysis

-Age- Primary teeth and newly erupted teeth have large pulp chambers- more susceptible to damage from vibrations and heat.

Oral conditions- hypersensitive teeth; demineralized enamel surfaces, exposed dentin

-Restorations- Veneers, cast crowns, composite restorations- avoid these localized areas; place ultrasonic tip adjacent or apical to restoration- use dental chart and radiographs for guidance.
