Putri, Firda Nirmala (2019) Analisa Pelepasan Ion Nikel dan Jenis Korosi pada Kawat NiTi, Thermal NiTi, dan CuNiTi dalam Saliva Buatan. Sarjana thesis, Universitas Brawijaya.
Abstract
Kawat merupakan salah satu komponen penting dalam perawatan ortodonti. Di dalam rongga mulut, kawat ortodonti akan selalu berkontak dengan saliva yang nantinya dapat memicu pelepasan ion logam. Peristiwa terlepasnya ion logam akibat kontaminasi logam dengan cairan disebut peristiwa korosi. Salah satu jenis kawat yang paling sering digunakan dalam perawatan ortodonti adalah kawat NiTi yang mempunyai beberapa jenis diantaranya kawat Thermal NiTi, dan CuNiTi. Tujuan dari penelitian ini adalah untuk melihat perbedaan pelepasan ion nikel pada kawat NiTi, Thermal NiTi, dan CuNiTi yang direndam dalam saliva buatan serta melihat perbedaan jenis korosi secara mikro yang terjadi pada kawat setelah direndam saliva buatan selama 30 hari dan 45 hari. Jenis penelitian ini adalah penelitian eksperimental laboratoris yang dilakukan secara in vitro menggunakan rancangan berupa The Post Test Only Grup Design. Sampel yang digunakan untuk pengamatan pelepasan ion nikel berjumlah 24 dengan 6 kelompok yang berbeda dan dibagi menjadi 2 waktu perendaman yaitu 30 hari dan 45 hari, sedangkan sampel yang digunakan untuk pengamatan jenis korosi secara mikro berjumlah 6. Pelepasan ion kemudian diuji menggunakan alat AAS (Atomic Absorbtion Spectometry) dan jenis korosi mikro diuji menggunakan alat SEM (Scanning Electron Microscope). Data hasil penelitian kemudian dianalisis menggunakan uji statistik Shapiro-Wilk, Levene’s Test, One Way ANOVA (Analysis of Varian), uji lanjutan LSD (List Significant Differences) dan uji Chi-Square. Hasil penelitian ini menunjukkan adanya perbedaan pelepasan ion nikel dan perbedaan jenis korosi secara mikro pada kawat NiTi, Thermal NiTi, dan CuNiTi.
English Abstract
Archwire is one of the important components in orthodontic treatment. In the oral cavity, orthodontic archwire always comes into contact with saliva which can later trigger the release of metal ions. An event in which metal ion is released due to contamination between metal and liquid is called corrosion. One type of archwire commonly used in orthodontic treatment is NiTi wire which has several types including Thermal NiTi and CuNiTi wires. This study aims to determine the differences in terms of nickel ion release in NiTi, Thermal NiTi, and CuNiTi wires soaked in artificial saliva, and to determine the different types of micro-corrosion that occurred on the wire after 30 days and 45 days of artificial saliva soaking. The study is of laboratory experimental study conducted in vitro using a design in the form of The Post Test Only Design Group. The number of samples used in the observation of the nickel ion release amounted to 24 samples consisting of 6 different groups, and divided into 2 different periods: 30 days and 45 days, moreover the number of samples used in the observation in terms of corrosion type amounted to 6 samples. The ion release was tested using AAS (Atomic Absorption Spectometry) and the type of micro-corrosion was tested using a SEM (Scanning Electron Microscope) tool. The results were then analyzed using the Shapiro-Wilk statistical test, Levene’s Test, One Way ANOVA (Analysis of Variance), LSD (List Significant Differences) and Chi-Square test. The results indicate differences in nickel ion release and micro-corrosion in NiTi, Thermal NiTi, CuNiTi wires.
