COMPOSITION
1 mL of this suspension contains 50 mg sodium fluoride, equivalent to 22.6 mg fluoride, in an alcoholic solution of natural resins.
PROPERTIES
Duraphat® displays a strong desensitizing effect when applied to affected dentinal surfaces. It is remarkably water tolerant and covers even moist surfaces with a well-adhering film of varnish, setting in saliva and obturating orifices of the dentinal tubules, providing desired reduction of patency to the tooth pulp.
INDICATIONS
Treatment of dentinal hypersensitivity.
APPLICATION
Depending on the access, Duraphat® fluoride varnish can be applied by use of cotton swabs, a brush or with a probe. The natural color provides visual control. Duraphat® covers even moist teeth with a film of varnish for several hours with obturation of openings of dentinal tubules. Application of the varnish is extremely rapid. Since no drying is required, the patient can leave immediately after the application. It is recommended that the patient does not eat hard foods or brush for at least two hours after the application.
CONTRAINDICATIONS
Duraphat® is contraindicated in patients with ulcerative gingivitis or stomatitis or known sensitivity to colophony (kolophonium) or other ingredients. Not for ingestion during application (not for systemic treatment).
INTERACTIONS WITH OTHER SUBSTANCES
On the day of Duraphat® application, other fluoride preparations, such as fluoride gels, should not be administered. Routine regimens of fluoride tablets should be suspended for several days after treatment.
ADVERSE REACTIONS
In case of disposition to allergic reactions, edematous swellings have been reported only in rare instances, especially after application to extensive surfaces. In extremely rare instances, attacks of dyspnea have occurred in asthmatic children. Patients known for sensitive stomach may occasionally experience nausea with extensive applications. In any case of intolerance, the varnish layer can easily be removed by brushing and rinsing.
