In der zahnärztlichen Praxis sollten Dentinadhesive mit optimalen werkstoffkundlichen
Eigenschaften und möglichst geringem toxischen Effekt auf das Pulpa–Dentin–System
zur Anwendung kommen. In der vorliegenden Studie wurde untersucht, ob verschiedene
Lichthärtegeräte einen Einfluss auf die toxische Wirkung unterschiedlicher Dentinadhäsive
haben. In einem Zellkulturmodell wurde an humanen gingivalen Fibroblasten der Einfluss
des Polymerisationsresultats nach Belichtung mit verschiedenen Geräten untersucht.
Die Ergebnisse zeigten, dass die Lichthärtegeräte den zytotoxischen Effekt der Dentinadhäsive
deutlich beeinflussen. Aus diesem Grund scheint eine optimale Abstimmung zwischen
dem Dentinadhäsiv und dem Lichthärtegerät eine wichtige Voraussetzung zu sein, um
die toxischen Einflüsse auf das Pulpa– Dentin–System zu minimieren.
In dental practice, one should use dental adhesives with the optimal technical characteristics
and the least toxic influences on the pulpa dentin system. In the present study it
was tested if various light curing units have an influence on the cytotoxic action
of different dentin adhesives. Human gingival fibroblasts were used in a cell culture
model to test the effect of different adhesive systems after polymerisation with various
light curing units. The results show that the influence of the light curing units
on the cytotoxic effect of the dental adhesives was clearly evident. An optimal tuning
between dentin adhesive and light curing unit is an important prerequisite for reducing
the toxic effects on the pulpa dentin system.
