Topical Fluoride

Mayra Aguilar and Kathy Cronin

What is fluoride?

Comes from the element fluorine Exist only as a fluoride compound Fluorine is a part of minerals in rocks and

soil. A small amount of soluble fluoride is present

in all water sources. Fluoride is also present in all foods and

beverages, to some extent.

Benefits of Fluoride

Prevents and reverses the early signs of decay

Makes the tooth structure stronger and more resistant to acids formed from bacteria

Remineralizes areas in which acid attacks have already begun.

Topical Fluoride

Topical fluorides are applied directly to the tooth enamel

It strengthens teeth and makes them more resistant to decay

Topical fluorides include toothpastes, mouth rinses, and fluoride treatments in the dental office

Types of Professionally Applied Fluoride

Varnish Gel Foam

Fluoride Varnish

5% NaF (pH 7.0) = 22,600ppm Fluoride Easier to apply in younger children Takes less time Less patient discomfort Greatest patient acceptability Fast drying Reduce sensitivity

Up to 24 weeks

Fluoride Gels

Acidulated phosphate fluoride (APF)(pH 3.5) = 12,300 ppm Fluoride or

2.0% NaF (pH 7.0) = 9040 ppm Fluoride Higher patient acceptability compared to

foam 4 Minute Application Time

Fluoride Foams

APF (pH 3.5) = 12,300 ppm Fluoride or 2.0% NaF (pH 7.0)= 9040 ppm Fluoride 4 minute application time Bad taste, less patient acceptability Requires 1/5 the quantity by weight to cover

the same arch compared to gel

Who Benefits from Topical Fluoride?

All people benefit from topical fluoride applications

People who are moderate to high caries risk benefit most

Caries Risk Categories

Low risk all ages– No incipient or cavitated primary or secondary

carious lesions during the last 3 years and no factors that increase caries risk*

Caries Risk Categories

Moderate risk (0-6 years old)– No incipient or cavitated primary or secondary

carious lesions during the last 3 years but the presence factors that increase caries risk*

Caries Risk Categories

Moderate risk (older than 6 years old)– 1 or 2 incipient or cavitated primary or secondary

carious lesions during the last 3 years but the presence factors that increase caries risk*

Caries Risk Categories

High risk (0-6 years old)– Any incipient or cavitated primary or secondary

carious lesions during last 3 years– Multiple factors that increase caries risk*– Low socioeconomic status– Suboptimal fluoride exposure– Xerostomia

Caries Risk Categories

High risk (older than 6 years old)– 3 or more incipient or cavitated primary or

secondary carious lesions during last 3 years– Multiple factors that increase caries risk*– Low socioeconomic status– Suboptimal fluoride exposure– Xerostomia

Some Factors that Increase Caries Risk include

High titers of cariogenic bacteria Poor oral hygiene Prolonged nursing or bottle use Poor family dental health Irregular dental care Presence of exposed root surfaces Physical or mental disability Alcohol / drug abuse, eating disorders

Clinical Recommendations for Application Intervals

Low caries risk (all ages)– May not benefit from additional topical fluoride– Fluoridated water and fluoride toothpaste may be

enough

Moderate risk (0-6 years)– Varnish application every 6 months

Moderate risk (6 and older)– Varnish or (1.23% APF) gel every 6 months

Clinical Recommendations for Application Intervals

High Risk (0-6 years old)– Varnish every 3 months or 6 months

High Risk (6 and older)– Varnish or (1.23% APF) gel every 3 or 6 months

Our Recommendations: Fluoride Varnish for All Ages!

Easy to apply Better patient tolerability Faster to apply Applied directly to each tooth Fluoride compound is less acidic Dries fast so young kids don’t ingest excess

fluoride Great for dentin hypersensitivity
