Abstract

Aim:

To prevent decalcification during orthodontic treatment using fixed appliances, many orthodontists use sealants to protect the enamel surface around the brackets. If the patients’ oral hygiene is insufficient, air polishing devices are often used to clean the teeth. The aim of this study was to investigate the effects of air polishing on the sealant.

Material and Methods:

Three sealants (Pro Seal™, OrthoSolo™, and Seal&Protect® were used in this study. Each was applied on the surface of 30 extracted human teeth. The enamel surfaces of 10 teeth each were then air polished with the sodium-bicarbonate-based powder (Air-Flow®) 5 or 10 seconds, or the glycine-based powder (Clinpro™ Prophy) for 10 seconds.

Results:

The sealant had become thinner, revealing minor defects after 5 seconds of air polishing using the sodium-bicarbonate-based powder, practically disappearing after 10 seconds. Use of the glycine-based powder allowed longer air-polishing times, but the sealant surface also showed minor defects thereafter.

Conclusion:

Reliable protection against demineralization may be seriously compromised after sealed tooth surfaces are cleaned with air-polishing devices. This finding correlates with the type of powder and air-polishing time.

Zusammenfassung

Ziel:

Um Demineralisationen während einer Multibracketbehandlung zu vermeiden, versiegeln viele Kieferorthopäden das Bracketumfeld. Ist die Mundhygiene suboptimal, werden die Zähne mit Hilfe von Pulver-Wasser-Strahlgeräten gereinigt. Die vorliegende Arbeit sollte die Frage klären, ob die Reinigung mit Pulver-Wasser-Strahlgeräten und verschiedenen Strahlmitteln die Schicht der Glattflächenversiegelung beeinträchtigt.

Material und Methodik:

Drei Glattflächenversiegler (Pro Seal™, OrthoSolo™, Seal&Protect®) wurden auf je 30 extrahierte Zähne aufgetragen. Anschließend wurde die Oberfläche bei je 10 Zähnen 5 bzw. 10 Sekunden mit einem Natriumbikarbonat-basierten Strahlmittel (Air-Flow®) bzw. 10 Sekunden mit einem Glycin-basierten Strahlmittel (Clinpro™ Prophy) behandelt.

Ergebnisse:

Nach 5 Sekunden Behandlung mit einem Natriumbikarbonat-basierten Strahlmittel war die Versieglerschicht ausgedünnt bzw. wies Lücken auf. Nach 10 Sekunden war der Versiegler nahezu abgetragen. Die Verwendung von Glycin-basierten Strahlmitteln ermöglicht längere Strahlzeiten, wobei auch hier die Glattflächenversiegelung kleine Schäden aufwies.

Schlussfolgerung:

Nach der Zahnreinigung mit Pulver-Wasser-Strahlgeräten kann abhängig vom verwendeten Strahlmittel und von der Strahldauer unter Umständen nicht mehr mit der gewünschten Schutzfunktion der Glattflächenversiegelung gerechnet werden.
