Daftar Isi:
- The Begg Technique is one of fixed orthodontic treatment which uses wire that is produced by G & H Factory, those are: regular type, special type, special plus type, premium type, premium plus type, and supreme type which each of it contains different carbon. The research about Australian Wire is still limited especially the research about the effect of saliva towards the use of the arch wire. This research is aim to know the influence of the length of soaking Australian Wire of regular type, special type, and premium type towards the release of ion nickel and chromium inside the saliva made by 3,5 pH. The research was conducted to 90 Australian Wires (30 regular type wires, 30 special type wires, and 30 premium type wires). Each of those wires was soaked into saliva made by 3,5pH and the length of soaking were 1, 7, 14, 28, 35, and 42 days to get to know the release of ion nickel and chromium from saliva. The result of research showed that the release of ion chromium was not detected in the entire process of soaking. Releasing ion nickel of soaking process in day 42 was significantly different compared to the soaking process in day 1, 7, 14, 28, and 35 (p<0,05). Releasing ion nickel on the Australian Wire of premium type was significantly different with the regular and special types (p<0,05). Releasing ion nickel happened in the process of soaking in day 1, 7, 14, 28, 35, and 42. It happened of either regular, special or premium type (p<0,05). The conclusion of this research was that the biggest of releasing ion nickel happened in day 42 of soaking process. Meanwhile releasing of ion chromium was not detected on the entire process of soaking. Premium type of Australian Wire released the biggest ion nickel in day 42 of soaking process.
