Clinical Trial Summary

The goal of the study was to ascertain the influence of dental caries and teeth position as well as the type and amount of the applied dental materials (DMs) on the oxidative stress (OS) status in gingival crevicular fluid (GCF).


Description:

Six DMs were tested by investigators, each sealed in one session: amalgam (Amg), zinc phosphate cement (ZnPhC), zinc polycarboxylate cement (ZnPoC), glass ionomer cement (GIC) and composites, Tetric EvoCeram (TEC) and Beautifil (BF).

The study included 88 dental outpatients. Oxidative stress parameters, including malondialdehyde (MDA), glutathione (GSH) and total superoxide dismutase (tSOD) activity were measured in GCF, before (day 0) and after treatment (7th and 30th day).

Antagonistically positioned healthy teeth were used as a control.

Beautifil placement
Before the BF was sealed GCF was taken, and then taken again on the 7th and 30th days after the applied treatment.
Zinc phosphate cement placement
Before the ZPhC was sealed GCF was taken, and then taken again on the 7th and 30th days after the applied treatment.
Zinc polycarboxylate cement placement
Before the ZPoC was sealed GCF was taken, and then taken again on the 7th and 30th days after the applied treatment.
Glass ionomer cement placement
Before the GIC was sealed GCF was taken, and then taken again on the 7th and 30th days after the applied treatment.

Outcome

Type Measure Description Time frame Safety issue
Other Changes in tSOD activity in dental patients GCF after the applied treatments Activity of tSOD was measured before (0 day) and twice after the applied treatments (7th and 30th days). GCF was taken via the intracervical absorption technique. Control GCF (from mirror-positioned health teeth) was taken once before the treatment. 0th, 7th and 30th days.
Primary Changes in the levels of MDA in dental patients GCF after the applied treatments The concentration of MDA in GCF was measured before (0 day) and twice after the applied treatments (7th and 30th days). GCF was taken via the intracervical absorption technique. Control GCF (from mirror-positioned health teeth) was taken once before the treatment. 0th, 7th and 30th days.
Secondary Changes in the levels of GSH in dental patients GCF after the applied treatments Concentration of GSH in GCF was measured before (0 day) and twice after the applied treatments (7th and 30th days). GCF was taken via the intracervical absorption technique. Control GCF (from mirror-positioned health teeth) was taken once before the treatment. 0th, 7th and 30th days.
