“…This result was in line with research by Senkutvan et al ,[ 25 ] which showed a significant increase in Ni ion release from CuNiTi archwires with three immersion periods (one, two, and three weeks) – the highest was in the third week. Habar and Tatengkeng[ 26 ] also did similar research using 33 and 66 days of immersion. Their result also displayed a significant increase over time.…”

OBJECTIVE: Sodium fluoride (NaF) is commonly used in oral hygiene products, leading to corrosion and reduced archwire properties. In addition, ion release can cause allergies and become toxic to the oral environment. This research aimed to observe the Nickel (Ni) and Copper (Cu) ions released that affected initial corrosion as deflection and surface roughness changed in the Copper-Nickel-Titanium (CuNiTi) archwire. MATERIAL AND METHODS: The total samples were 54 copper-nickel-titanium (CuNiTi-Tanzo, American orthodontic®) archwires immersed in three solutions. Artificial saliva was used in the control group NaF 0.05%, and a NaF 0.15% solution was used in the intervention groups ( n = 6). The groups were divided into three observation times (two, four, and six weeks). Cu and Ni ions released, deflection, the surface roughness of the archwires, and solution acidities were recorded and analyzed. RESULTS: Ni and Cu ion release and surface roughness of the CuNiTi archwires significantly increased as the NaF concentration increased. The Ni ion release improved along the immersion period; the opposite was true for the Cu ion release. The solutions became more alkaline after the CuNiTi archwires were immersed. The pH and the archwires’ deflections of the three solutions did not show significant differences. CONCLUSION: The NaF increased Cu-Ni ion release and surface roughness but not the deflection force of the CuNiTi. The increase was affected by the concentration and duration of immersion.

“…One of the electrolytes that play a role in releasing ions is chloride ion. Chloride can damage the oxide layer on the alloy surface, causing the release of ions [17]. Artificial saliva contains organic components in the form of proteins which can act as an electrolyte medium, thus triggering chemical reactions.…”

Alloys in oral cavity always interact with dynamic oral environment, such as pH, temperature, salivary conditions, and dietary habits. Coffee can further decrease pH in the oral cavity. Thus, coffee may increase the release of metal ions that may lead to various health diseases. This study aimed to quantitively investigate the effect of brewed Robusta coffee on the nickel ion release and their morphological structures; Methods: 20 alloy specimens were divided into 4 groups and placed in solutions for 48 and 168 h: (1) distilled water, (2) artificial saliva, (3) Robusta coffee, and (4) mixture of artificial saliva and Robusta coffee. AAS, XRF, and SEM were used for examinations; Results: The release of Ni2+ was found in all groups and robust release were found in the coffee only and mixture of coffee + artificial saliva solution after 168 h. Likewise, SEM showed that internal oxidation was high after 168 h of immersion; Conclusions: The concentration of nickel increased in saliva of low pH due to brewed coffee. Though the release of these ions is still within the tolerable amount in human body, it should be realized that it usually lasts for months or years. Dentists should be cautious when using instructions for patients with a history of allergies especially for dietary with low acidity.

“…Kawat CuNiTi merupakan salah satu jenis kawat yang banyak digunakan pada peeawatan ortodonsia, jenis kawat ini merupakan pengembangan dari kawat NiTi dengan penambahan elemen copper untuk meningkatkan kualitas dari kawat. Pada umumnya kandungan kawat CuNiTi terdiri dari 42,99% titanium, 49,87% nikel, 0,50% kromium dan 5,64% copper [3]. Kawat CuNiTi memiliki beberapa kelebihan diantaranya, elastisitas yang lebih besar dan hysteresis yang lebih rendah yang memungkinkan penghasilan gaya konstan yang lebih lama selama deaktivasi yang menguntungkan untuk pergerakan gigi [4].…”

The surface roughness of orthodontic archwires is an essential factor that deter- mines the effectiveness of arch-guided tooth movement. CuNiTi-based wires are widely used in orthodontic treatment, but the oral environment can trigger corrosion of CuNiTi orthodontic wires. The tannin content in avocado seed extract can be used as a corrosion inhibitor through two working mechanisms, namely, forming a passive layer and an adsorption process. The aim of this research is to examine the effect of avocado seed extract as a corrosion inhibitor on the surface roughness of orthodontic CuNiTi wire. The as- retacngular 17 x 25 inch CuNiTi wire were taken in 4 group (1 control group soaked in artificial saliva and 3 treatment groups soaked in avocado seed extract ). Samples were immersed in avocado seed extract with concentrations of 1,5 g/L, 2 g/L and 2,5g/L for 7 days. For surface roughness was test Surface Roughness Average analysis. One way ANOVA test showed that there was a significant difference between the control group and all treatment groups in the surface roughness test with a value of p = 0.000. Post Hoc LSD test showed that there were no significant differences between treatment group 2 and treatment group 3 with a p value = 0.122. Providing avocado seed extract with tannin content at concentrations of 1.5 g/L and 2 g/L can reduce surface roughness on CuNiTi wire due to the corrosion process.
