Abstract
Objective: In this study, a short-term denture soft liner was incorporated with Eugenia caryophyllata, Illicium
verum, and Citrus hystrix essential oils. An influence of these essential oils on initial viscoelastic properties of
the modified soft liner was investigated.
Materials and methods: Various concentrations of three essential oils were added into the short-term soft liner. The initial viscoelasticity of these materials was evaluated by an oscillating plate rheometer. There parameters including a gelation time, initial elastic and viscous moduli at 360 seconds (G’360 and G”360) were determined. Five independent experiments were done.
Results: For the soft liner without additive, its gelation time was 92 seconds, approximately. The G’360 and G”360 of the material were 95 and 26 kPa, respectively. After incorporating all essential oils into the soft liner, both G’360 and G”360 were decreased in a dose-dependent manner. The addition of 10 - 20 %v/v of E. caryophyllata oil and 20 - 30 %v/v of I. velum oils did not significantly influence on the gelation time of the soft liner. Whereas, the incorporation of C. hystrix oil at 35 %v/v, 40 %v/v, and 45 %v/v significantly prolonged the gelation time of the soft liner to be 160, 204, and 322 seconds, respectively.
Conclusions: Higher concentrations of the essential oils diminished initial moduli of the short-term soft liner.
E. caryophyllata and I. velum oils seemed to be more appropriate additives without an alteration in the gelation time of the soft liner. The incorporation of C. hystrix oil into the short-term soft liner dramatically changed both gelation and initial moduli.
