Role of Topical Fluorides in Preventive Dentistry | Importance of Topical Fluorides in Preventive Dentistry.
Fluorides play an Important Role in Preventing dental caries formation. There are two delivery systems is available for fluoride application one is Topically and another one is Systemic. Here We are going to see about the role of topical fluorides in dentistry and what are the available topical fluorides in day-to-day life.
As the name itself says, topical fluorides are applied directly to the surface of the tooth. Due to the direct interaction with the teeth, it effectively helps in preventing dental caries.
Role of Topical Fluorides in Preventive Dentistry
Inhibits Demineralization
When we applied fluoride topically, it penetrates into the tooth minerals and prevents the dissolution of mineral contents of the tooth against the acid produced by the bacteria.
Enhances Remineralization
We all know Saliva is Supersaturated with Calcium and Phosphate it absorbs the mineral content into the teeth. Fluoride speed ups this remineralization process by adsorbing to the surface and bringing calcium and phosphate ions together to enhance the remineralization.
Interference with Microorganisms
A low concentration of Fluoride causes bacteriostatic in nature and controlling the growth of bacteria by inhibiting without killing them. A mild amount of fluorides present in the plaques are inhibited the acid metabolism which is responsible for caries formation.
Increased Rate of Posteruptive Maturation
Newly erupted tooth have hypo mineralized areas has more risks of caries. Fluoride enhances the increased rate of remineralization in the hypo mineralized areas and prevents dental caries.
Indications of Topical Fluoride Application
It is indicated in patients having tooth sensitivity. It is applied to the patients who are having more risk of caries on the tooth surface as well as on the root surface. And it is indicated, there is a presence of white spots.
Types of Topical Fluoride Application
The Topical Fluoride can be applied in two ways. They are
- Professionally Applied Topical Fluoride
- Self Applied Topical Fluoride
Professionally Applied Topical Fluoride
A. Aqueous solution
B. Fluoride Varnishes
C. Fluoride Foam
D. Flouride Prophylactic Paste
E. Restorative Materials Contains Flouride
F. Fluoride Containing Devices
Aqueous solution
The aqueous solution is prepared by two techniques. One is prepared by 2% sodium fluoride containing technique which is also known as Knutson's technique and another one is prepared by 8% of stannous fluoride containing technique which is also known as muhler's technique.
Fluoride Varnishes
Fluoride varnishes are the adherent material which is applied to the prepared cavity and prevents sensitivity of the dentin and has good anti-cariogenic property. There are three types of fluoride varnishes. They are Duraphat, Fluorprotector, and carex.
Fluoride Foam
Acidulated Phosphate Fluoride Gel is used in the gel. Foam is used to prevent fluoride overdosage.
Fluoride Prophylaxis Paste
It is used to clean the tooth surface by removing deposits and polish the hard tissues, even restorations.
Restorative Materials Containing Fluorides
It includes glass ionomers, dental amalgam, resin-modified glass ionomers, resin composites, pits, and fissure sealants. They are not constantly releasing fluorides. They have a high rate of releasing fluorides in the initial time and get decreased over a long period of time. It has good anti-cariogenic properties.
Fluoride Containing Devices
This topical system slowly releasing the fluorides over a long period of time. There are three types of fluoride-containing devices. They are Glass beads, Copolymer membrane type, Mixture of sodium fluoride & hydroxyapatite.
Self Applied Topical Fluoride
A. Fluoride Gels
B. Fluoride Dentrifices
C. Fluoride Mouthrinses
Fluoride Gels
Self-applied fluoride gels are consist of sodium fluoride, stannous fluoride, and acidulated phosphate fluoride. The patient is advised to brush the teeth with this gel for 1 minute and not to swallow the excess gel. This gel is used once a day. It is not recommended in children below six years of age.
Fluoride Dentrifices
The main purpose of the denitrifies is to clean and polish the tooth surface. There are different types of fluoride denitrifies available. They are,
• Stannous Fluoride Dentrifices
• Sodium Fluoride Dentrifices
• Monofluorophosphate
• Aminofluorophosphate
Fluoride Mouthrinses
It is easily prepared in our home by dissolving 200mg of sodium fluoride tablets in 5 teaspoons of fresh and clean water. Sodium fluoride is most commonly used in fluoride mouth rinses. Patients are advised to rinse well and spit.
