Abstract

Objective

The aim of this study was to assess the biocompatibility of orthodontic bands following exposure to the human oral environment.

Methods

Cell adherence and cell morphology of gingival fibroblasts grown on 32 orthodontic bands were tested. The bands were in place intraorally for 6 to 37 months.

Results

We observed cell adherence in 76% of the previously plaque-free surfaces. Cell morphology was 50% spherical and 50% elongated. The surfaces that had had plaque attached demonstrated cell adherence in 84% of the given areas; those cells were spherical in 42% and elongated in 58%.

Conclusion

We conclude that individual oral hygiene habits during orthodontic treatment seem to have no effect on the biocompatibility of orthodontic bands, as we failed to discern a difference in either cell adherence or cell morphology in areas with and without prior plaque attachment.

Zusammenfassung

Ziel

Ziel der Studie war, die Biokompatibilität orthodontischer Bänder nach Exposition im humanen oralen Milieu zu untersuchen.

Methode

Nach einer intraoralen Verweildauer von 6 bis 37 Monaten wurden die Zellanhaftung und die Zellmorphologie auf 32 orthodontischen Bändern untersucht.

Ergebnisse

Auf 76% der ehemals plaquefreien Oberflächen konnte eine Zellbesiedelung festgestellt werden. Die Morphologie der Zellen war zu 50% rund, zu 50% spindelförmig. Auf den ehemals plaquebesiedelten Oberflächen konnte sogar in 84% der gewählten Areale eine Zellbesiedelung festgestellt werden. In 42% der Fälle wurden runde Zellen beobachtet, während in 58% spindelförmige Morphologien auftraten.

Schlussfolgerung

Da sowohl bei ehemals plaquefreien als auch plaquebesiedelten Oberflächen kein signifikanter Unterschied in der Zellbesiedelung sowie der Zellmorphologie gefunden werden konnte, darf man annehmen, dass die Exposition im Mund des Patienten bei unterschiedlichen Hygieneverhältnissen keinen Einfluss auf die Biokompatibilität orthodontischer Bänder nimmt.
