The Effect of Herbal Mouthwashes on the Force Decay of Elastomeric Chains: An In-vitro Study

Background: This in vitro study aimed to evaluate the effect of four herbal mouthwashes on the force decay of two types of clear short elastomeric chains (Regular and Extreme) at various time intervals. Materials and methods: Four hundred forty pieces of both types of elastomeric chains with 19 mm length were utilized in this study. The force was measured, using digital scale immediately, after one-day immersion in distilled water and after 1, 2, 3 and 4 weeks immersion in the specific mouthwash for one minute twice daily then washed and kept in distilled water at 37°C. Force decay was calculated and compared among different elastic types, mouthwashes and time intervals using t-test and one-way ANOVA then Tukey’s tests. Results: The force degradation of regular type was significantly higher than extreme one. With time, the force decay increased significantly in both types. There was non-significant difference among the mouthwashes in the first and second weeks while the opposite in the third and fourth especially with the control group. Conclusions: The extreme type is preferred over the regular one because of its low force decay and the tested mouthwashes have no clinical significant effect on the force degradation over time in comparison with distilled water.
