Eugenol-based temporary luting cement possesses antioxidative properties.
BACKGROUND
Antioxidants protect against reactive oxygen species and expose beneficial anti-inflammatory activity when in contact with biological tissues. Dental materials that are used as temporary luting on fixed dental restorations are often in contact with injured gingival tissue, hence they should contain anti-inflammatory characteristics that are essential after prosthetic procedures preceding cementation of final restauration.


OBJECTIVE
The aim of this study was to investigate the antioxidant effect through the oxidation inhibition (OI) of mixed dental cement for temporary luting or their liquid component.


METHODS
Eight study groups were prepared each by ten samples: 1) ex tempore preparation of zinc-oxide eugenol paste (Kariofil Z Galenika, Serbia), 2) Viko Temp paste (Galenika, Serbia), 3) Temp Bond NE paste (Kerr, Germany), 4) ScutaBond (ESPE, Germany), 5) Cp-CAP paste (Germany, Lege Artis) and oil component of 6) Kariofil Z, 7) Viko Temp and 8) Cp-CAP. The samples were subjected to spectrophotometer to measure OI 2,2'-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid) (ABTS) using Randox kit, United Kingdom. The control samples were pure ascorbic acid (1% w/v).


RESULTS
High values of OI exposed materials (groups 1, 5, 6, 7, 8) with content of eugenol (or its derivates) in the range of 100-88.8% were statistically more significant than the values of non-eugenol substances (groups 2, 3, 4) with the range of 8.2-43.5%.


CONCLUSIONS
Eugenol containing temporary fixation materials show significant antioxidative properties and therefore they may be used in those clinical situations where surrounding gingival tissue is injured during restorative procedure.
