Eugenol-based temporary luting cement possesses antioxidative properties

Area of Science:

• Dental Materials Science
• Biomaterials
• Oxidative Stress Research

Background:

• Antioxidants combat reactive oxygen species and possess anti-inflammatory effects beneficial for biological tissues.
• Temporary dental luting cements contact injured gingival tissues, necessitating anti-inflammatory properties for post-procedure healing.

Purpose of the Study:

• To evaluate the antioxidant capacity, specifically oxidation inhibition (OI), of temporary dental luting cements and their liquid components.

Main Methods:

• Eight groups of dental materials were tested, including zinc-oxide eugenol and non-eugenol cements.
• Oxidation inhibition (OI) was measured using the ABTS assay via spectrophotometry.
• Ascorbic acid served as the control for antioxidant activity.

Main Results:

• Eugenol-containing materials exhibited significantly higher OI values (88.8–100%) compared to non-eugenol materials (8.2–43.5%).
• Materials with eugenol or its derivatives demonstrated superior antioxidant effects.

Conclusions:

• Temporary fixation materials incorporating eugenol possess notable antioxidative properties.
• These eugenol-containing cements are suitable for clinical use when gingival tissue is compromised during restorative procedures.
