Effect of Commonly Used Beverage Soft Drink andMouthwash on Force Delivered by Elastomeric Chain: A Comparative InVitro Study

摘要

>Background: The objective was to evaluate and compare the effect of Coca-Cola®, tea, Listerine® mouthwash on the force delivered by elastomeric chain in vitro. Materials and Methods: Four specimen groups (distilled water, Coca-Cola®, tea, Listerine® mouthwash) with a total sample size of 480 specimens. A specimen is described as a four link grey close elastomeric chain. Jigs, each with a series of pins set 25 mm apart, was used to hold stretched elastomeric chains at a constant length. These jigs allowed for complete submersion of the elastomeric chain in a water bath throughout the test period, as well as the dipping of elastomeric chains in respective control and test solutions. For 60 s, twice a day, groups were exposed to the respective solutions, the two daily exposure was separated by 9 h and force measurements were taken at six time points during the experiment, that is, 1 h, 24 h, 7 days, 14 days, 21 days, and28 days. Force measurements were made by Instron machine by asingle blinded examiner with the help of a second examiner.>Results:It was found out that there was highly significant differencebetween groups control, Coca-Cola®, Listerine®, and tea as well asthere was highly significant (p < 0.01) between time periods. Groupversus time was also highly significant (p < 0.01). For all groupssubstantial amount of force decay occurred until 7 days. Thecontrol group reached plateau between 7 and 14 days and thensuddenly decreased from 14 days to 28 days. The Coca-Cola® and theListerine® group reached a plateau between 7 and 21 days thendecrease between 21 and 28 days. The tea group showed plateau phasebetween 7 and 28 days. After 28 days in the control group, 25%force decay occurred while the test groups force decay of 30-50%occurred.>Conclusion:Coca-Cola®, Listerine® mouthwash, and tea cause an increase in forcedecay of elastomeric chains over time. Tea caused highest forcedecay followed by Listerine® and Coca-Cola® when compared to controlgroup.>How to cite the article:Kumar K, Shetty S, Krithika MJ, Cyriac B.
