ABSTRACT

Objectives: The Aim Of This Study Was To Evaluate The Relation Between Force Decay Of Elastomeric Chains And Alcohol Concentrations Commonly Found In Mouth Rinses. Methodology: 160 Segments Of Elastomeric Chains Of Two Types Conventional And Memory Chain Were Stretched On Test Jig. The Specimens Were Divided Into Four Groups And Exposed Twice A Day To Three Different Mouthwashes With Different Alcohol Content (Listerine Original 26.7%, Listerine Whitening Refresh 8%, And Listerine Zero 0% Alcohol) Plus A Control Group Of Artificial Saliva For A Total Time Of 28 Days. Force Measurements Were Taken At Six Time Points (initial, 1 Day, 7 Days, 14 Days, 21 Days, And 28 Days) With A Digital Force Gauge.

Results: There Were No Significant Differences Among Groups. Statistically Significant Effects Of Time On Force Decay Were Seen In All Groups. Statistically Significant Difference Was Found Between Conventional And Memory Chains. Conclusion: Alcohol Did Not Cause An Increase In Force Decay Of Elastomeric Chains. Force Decay Of Memory Chains Much Less Than Conventional Power Chains.
