Pengaruh pH Larutan Asam terhadap Daya Tarik Magnetic Attachment 900 GF
Abstract
Background: Magnets are alloys that can attract certain metals such as iron, cobalt, nickel, and other alloys. Magnetic attachments used as denture retention for over 80 years. They reduce horizontal stress transfer to teeth and bone during denture insertion and removal. However, there is evidence that the magnetic force can be reduced under extreme conditions such as; high temperature, external environment, or changes in the chemical composition of the magnet due to corrosion and physical deterioration of the magnet. The purpose of this study was to determine the effect of pH of acidic solution on the attraction of magnetic attachment 900 GF.
Methods: This study is a laboratory experimental with randomised pre-post test design. Measurements in this study were taken before and after each sample was given an intervention. The number of samples was 3 consisting of dental magnetic attachment type neodymium magnet with Magteeth MT 900 brand. The data obtained were analysed univariately using the paired t-test method.
Results: Significant results were obtained in the paired t-test analysis for all samples tested with significance values sequentially 0.015; <0.001; 0.009 (p < 0.05).
Conclusion: The pH of the acidic solution has an influence, decreasing the attractiveness of the magnetic attachment 900 GF
Latar Belakang: Magnet merupakan paduan yang dapat menarik logam tertentu seperti besi, kobalt, nikel, dan paduan lainnya. Magnetic attachments digunakan sebegai retensi gigi palsu selama lebih dari 80 tahun. Alat tersebut mengurangi transfer stres horizontal ke gigi dan tulang pada saat pemasangan dan pelepasan gigi palsu. Namun didapatkan bukti bahwa gaya magnet dapat berkurang jika dalam kondisi ekstrim seperti; suhu tinggi, lingkungan eksternal, atau perubahan komposisi kimia magnet akibat korosi dan kerusakan fisik magnetnya. Tujuan penelitian ini untuk mengetahui pengaruh pH larutan asam terhadap daya tarik magnetic attachment 900 GF.
Metode: Penelitian ini merupakan eksperimental laboratoris dengan desain randomized pre-post test. Pengukuran pada penelitian ini dilakukan sebelum dan setelah masing-masing sampel diberi intervensi. Jumlah sampel adalah 3 yang terdiri dari dental magnetic attachment bertipe neodimium magnet dengan merek Magteeth MT 900. Data yang didapat dianalisis secara univariat menggunakan metode paired t-test.
Hasil: Didapatkan hasil yang signifikan pada analisis uji paired t-test untuk semua sampel yang diuji dengan nilai signifikansi secara berurutan 0,015; <0,001; 0,009 (p <0,05).
Simpulan: pH larutan asam memiliki pengaruh, menurunkan daya tarik magnetic attachment 900 GF
