Abstract

The effects of soft drinks can result in changes in the resiliency of orthodontic wires usually caused by carbonated or probiotic drinks. This type of drink with a low pH in this case carbonated drinks and probiotic drinks. This is a result of carbonic acid in carbonated beverages and lactic acid bacteria in probiotic drinks that are able to release nickel (Ni) and chromium (Cr) ions. The purpose of this study was to analyze the difference in resilience of orthodontic wire z -spring after soaking for 8 days. Method: Experimental research by pre and post test with control group design method, samples were used as many as 27 z-spring orthodontic wires and divided into 3 groups. Resilience measurement is performed before and after immersion is measured with UTM tool Research result: In carbornation soft drinks, there is a difference in resilience on the 0th day with the 4th day (p=0.047). Orthodontic wire stainless steel z- spring soaked probiotics obtained a value of p=0.038. Conclusion: There was a significant change in resilience between day 4 and day 8 of carbonated beverage immersion (p=0.001). Keyword: Probiotic, carbonation drink, orthodontic z- spring, resilience
