Abstract

Objective: In order to Investigate the difference of morphology and composition of Super-elastic NickelTitanium wire before and after submersed in artificial saliva with normal pH (pH 6:50) and acidic pH (pH3.75). Material and method: Super-elastic Nickel Titanium wire were divided into 2 groups. Each groupconsisted of 3 samples submerged in 150 ml of artificial saliva for 28 days. The first group was Super-elasticNickel Titanium wire submersed in artificial saliva with normal pH (pH 6.50) while the second group wassubmersed in artificial saliva with acidic pH (pH 3.75). Wire surface morphology was Analysed using ScanningElectron Microscope (SEM) while the wire composition was Analysed using Energy Dispersive X-raySpectroscopy (EDS. Result: Scanning Electron Microscope revealed a significant difference of surfacemorphology of super-elastic nickel titanium before and after submersed in artificial saliva between normal pH(pH 6.0) and acidic pH (pH 3.75). SEM investigation Showed a fibrous microstructure on the surface of superelasticnickel titanium before submersed in artificial saliva and became rough and showed many form of pittingor crevice corrosion after submersed in artificial saliva for 28 days. The chemical compositions in surfacemorphology were analysed using EDS Also showing a different result. The major compositions of super-elasticnickel titanium wire were the C, N, Ni and Ti and after submersed in artificial saliva for 28 days has made anyadditional elements O, Al, Si, P, Cl, Ca, K and Fe. Conclusion: the surface morphology of nickel titaniumsurface rugosity greater SEM Showed and presence of many forms of pitting or crevice corrosion aftersubmersed in artificial saliva with normal pH and acidic pH. The major surface composition of a super-elasticnickel titanium before submersed in artificial saliva were the C, N, Ni and Ti and as a major composition ofsuper-elastic nickel titanium before and after submersed in artificial saliva with normal pH (pH 6.0) and acidicpH (pH 3.75 ).

Abstract

Background: The interest and awareness for maintaining oral health is increasing.  It is not only confined to fillings and extractions, but also extend to orthodontic treatment. Orthodontic treatment aims to get normal occlusion, improves the health of the periodontal, dental health and facial aesthetics. Increased interest in orthodontic treatment was due to the high prevalence of malocclusion. The prevalence of malocclusion in Indonesian is still very high which is about 80% of the population. Orthodontic treatments change the circumstances surrounding the oral cavity, so that orthodontic appliance users who do not maintain oral hygiene are at risk for periodontal disease. Objective: to determine relationship between duration of the fixed orthodontic treatment with periodontal status and treatment needs among students in the Faculty of Dentistry, Universitas Muslim Indonesia Makassar in 2017. Materials and methods: This study is observational analytical study with cross sectional study design. The samples were 35 students in Faculty of Dentistry UMI Makassar using fixed orthodontic appliance. The method of data collection that checks the periodontal status and treatment needs was done by using an a Community Periodontal Index of Treatment Need (CPITN). The statistical analysis was done by using Chi-Square test. Results: Based on the statistical test, it is shown that there were relationship between duration of fixed orthodontic treatment with periodontal status (p = 0,004 < 0,01) and the periodontal treatment need (p = 0,004 < 0,01). Conclusion: There is  relationship between duration of fixed orthodontic treatment with periodontal status and treatment needs of the students in the Faculty of Dentistry, Universitas Muslim Indonesia in 2017.
