Evaluasi Kehilangan Gaya (Force Decay) Elastik Ortodontik akibat Perendaman Minuman Berkarbonasi

Abstract

Background: The losing force of orthodontic elastic can be caused by the acidic condition from consuming carbonated beverages. Objective: To know how much force loss on orthodontic elastic due to immersion in carbonated beverages. Methods: In this study, the sample was consisted of three groups, the control group was the artificial saliva, The treatment group 1 was the artificial saliva which added by the carbonated beverage, and the treatment group 2 was a carbonated beverage. Soaking was carried out at temperature of 37 C for 6, 1, 18, and 24 hours in the incubator. Then the force magnitude was measured by using a tensile drawn test, is Universal Testing Machine. Result: The T-test result showed significant difference between the control groups, treatment group 1, and treatment group 2. Conclusion: orthodontic elastic soaked in carbonated beverages group had double force loss compared with the group artificial saliva soaked in 24-hours.
