This document discusses different fluoride preparations for professional dental use. It outlines indications and contraindications for topical fluoride use. It describes the preparation, application, and precautions for acidulated phosphate fluoride solutions and gels, which are recommended for caries-prone individuals. Acidulated phosphate fluoride solutions are more effective than neutral gels because fluoride penetrates more deeply in an acidic environment. Neutral sodium fluoride gels can be used to avoid complications with dental restorations. In summary, the document provides guidance on topical fluoride therapies for dental professionals to help prevent tooth decay.

3. Indications for the Use of Topical Fluoride:
 Caries prone children and adults
 Patients with removable orthodontic appliances
 Salivary gland malfunction
 Arrested carious lesions
Contra-indications:
 Home use
 Children below 6 years of age

4. Acidulated phosphate fluoride Solutions
Preparation:
1.2 % NaF in 0.1 mol/L phosphate buffer with pH of
3.2
Applications:
 Apply directly with cotton pallet for 4 minutes ,
one quadrant treated at a time
 In children APF carried in special trays, treating
one arch at a time
 Annual or biannual application is
recommended

5. Precautions:
Drinking or eating should be avoided for 30 minutes after application
Advantage:
In APF solution fluoride is present as HF- while in non acidic solutions most of the fluoride is
as F- ion , So
 HF- Diffuses more readily than F-
 Fluoride from APF solutions penetrate more deeply into enamel
 More fluoride is deposited

6. Acidulated phosphate fluoride gels
Preparation:
Fluoride concentration=1.23% and gelling
agent=methyl or hydroxy methyl cellulose
Application:
 In adults; by applicator tray
 In children; with cotton pallet

7. Precautions:
Drinking and eating should be avoided for 30 minutes after application
Advantages:
 20 to 40 % reduction in caries incidence
 Easier to use with the help of special trays
 No spillage
 Less amount required
 Thixotropic

8. Neutral sodium Fluoride gels
 2.0 % NaF gels are available for office use
 APF should be avoided on sealants or if the
patient has composite porcelain restoration
as it’s little more acidic so it can etch the
porcelain. So, we use neutral sodium
Fluoride gels to restrain complications.
 Application and precautions are same as for
APF gels
