Perbedaan Defleksi Kawat Ortodonti Nikel-Titanium dan NiTi Epoxy Resin Coated pada Perendaman dalam Saliva Buatan dan Minuman Berkarbonasi
ABSTRACT: Deflection of
orthodontic wire can be changed by oral condition, for example acidic condition
caused by carbonated drink consumption. Objective: to analyze the difference in
deflection of Nickel-Titanium archwire and NiTi epoxy resin coated immersed by
artificial saliva and carbonated drink. Materials and Methods: This research
used four sample groups: NiTi non coated archwire immersed by saliva, NiTi non
coated archwire immersed by saliva mixed carbonated drink, NiTi coated archwire
immersed by saliva, and NiTi coated archwire immersed by saliva mixed
carbonated drink. The samples were immersed for 3.5 hours at 37° C in
incubator. The deflection was measured with Three Point Bending method using
Universal Testing Machine. Result and Conclusion: One Way Anova test result
showed significantly difference between coated and non coated group that
immersed by saliva with the groupimmersed by saliva mixed carbonated drink. In
conclusion, the deflection of Nickel-Titaniumarchwire and NiTi epoxy resin
coated archwire had decreased after immersed by carbonateddrink and
Nikel-Titanium archwire had higher deflection than NiTi epoxy resin coated
immersedby artificial saliva
