At a professional level, fluorine can be applied in a variety of ways:

• High concentration Collutories
• Gels
• Varnishes

High concentration collutories are less frequent since the other forms of application have been proved to be more efficient. Solutions made with Sodic Fluoride at 2%, Fluoride with pewter at 8% and solutions with Fluorophosphates acid (APF) can be used.

GELS

This is the most frequent treatment used at a dental clinic for topic fluoride application.

Gels with fluorine Phosphatoacid at 1.23% are used, and the most updated is the use of gels with sodic fluoride at 2%. The advantage of these gels is that they are less acidic and alter at a lesser degree the composite restorations and ceramics that the patient may have.

Different High Concentration Gels

They are applied using disposable buckets, both arches are placed at the same time and for a time lapse of no more than 4 minutes.

Rinsing must be avoided, but the remaining gel must be spitted out and eliminated in order to prevent the patient from swallowing it.

The buckets are filled with no more than 2.5 ml of gel, and a saliva aspirator must be placed as to prevent the patient from swallowing the saliva mixed with gel.

VARNISHES

Varnishes are used in dental clinics, they have the advantage that the fluoride applied, due to supporting lacquer, remains in contact with the teeth for a longer period of time, therefore increasing the possibility of fluorpatite formation.

It is advised that the patient does not drink anything for the next 30 minutes following the application, and also to avoid brushing teeth for the next 24 hours so that it is not eliminated.

The patient will perceive that in the hours following the treatment the adhered layer of fluoride falls.

Varnishes are recommended in children younger than 6 years old, since they tend to swallow the gels and with this method that is avoided.

It is also indicated in patients that can not tolerate, because of nauseas, the gel buckets. It is also recommended in mentally handicapped patients and in adults with a dental anti- sensitivity component.
