The Release of Nickel Ions and Microstructure of the Surface of the Nickel-Titanium Wire After Being Soaked in Tomato Juice and Oranges

Introduction

Nickel-Titanium (NITI) orthodontic wire is a popular choice in dental care due to its flexible and strong nature. However, the resistance of this wire to acids in food and drinks is a concern. Recent research has shown that acid exposure can trigger the release of nickel ions from the wire, which can cause allergic reactions and toxicity in the body. This study aims to examine the effect of tomato and orange juice on the release of nickel ions from NITI wire.

The Importance of Understanding Nickel Ions Release

Nickel ions release from NITI wire is a significant concern in the field of orthodontics. The release of nickel ions can cause allergic reactions, skin irritation, and even toxicity in the body. Therefore, it is essential to understand the factors that contribute to the release of nickel ions from NITI wire. This study focuses on the effect of tomato and orange juice on the release of nickel ions from NITI wire.

Research Methods

This study used an experimental laboratory method to compare the number of nickel ions released from NITI wire after being soaked in tomato juice, orange juice, and artificial saliva (as a control). The research methods used in this study are as follows:

NITI wire with a diameter of 0.016 inches and a length of 2 cm was divided into three groups: Tomato juice group, orange juice group, and control group (artificial saliva).
Each group consisted of 9 wire samples soaked in 15 ml of solution for 24 hours at 37 ° C.
After immersion, the solution was analyzed with an ICP-MS tool to measure the amount of release of nickel ions.
Wire surface microstructure was also observed using SEM to see changes that occur.

Research Results

The results of this study showed that the number of nickel ions separated from NITI wire was higher in tomato juice and orange juice compared to artificial saliva. Specifically:

*** Tomato juice group: *** The average release of nickel ions was 0.010 ± 0,000 ppm. *** Orange juice group: *** The average release of nickel ions was 0.009 ± 0,000 ppm. *** Control group (artificial saliva): *** The average release of nickel ions was 0.002 ± 0,000 ppm.

Data analysis using the Oneway Anova test showed a significant difference (p = 0.001) in the number of nickel ions release between the three groups, with tomato juice and oranges causing higher nickel ions.

SEM Observations

SEM observations on the surface of the NITI wire indicated the difference in microstructure between the treatment group and control, which indicates that acids in tomato juice and oranges can cause changes in the surface of the wire.

Conclusion and Implications

This study shows that exposure to tomato juice and oranges can increase the release of nickel ions from NITI orthodontic wire. This finding is important because it shows the potential for health risks associated with the use of NITI wire in the acidic environment.

Recommendations and Suggestions

It is necessary to do further research to understand the mechanism of releasing nickel ions and its long-term effects on health.
It is essential to consider other factors such as acid concentrations in food and drinks, the duration of exposure, and the condition of individuals in assessing the risk of releasing nickel ions.
For orthodontic patients, it is recommended to reduce the consumption of sour foods and drinks during orthodontic treatment.
It is necessary to consider the development of alternative materials that are more resistant to corrosion and release of nickel ions.

Note

This article aims to provide general information and is not intended to replace professional medical suggestions. Consult your dentist to get more information about orthodontic care and risks associated with NITI wire.

Future Directions

This study highlights the importance of understanding the factors that contribute to the release of nickel ions from NITI wire. Future studies should focus on the mechanism of releasing nickel ions and its long-term effects on health. Additionally, research should be conducted to develop alternative materials that are more resistant to corrosion and release of nickel ions.

Limitations of the Study

This study has several limitations. The study only examined the effect of tomato and orange juice on the release of nickel ions from NITI wire. Future studies should examine the effect of other acidic foods and drinks on the release of nickel ions. Additionally, the study only examined the short-term effects of nickel ions release, and future studies should examine the long-term effects of nickel ions release.

Conclusion

In conclusion, this study shows that exposure to tomato juice and oranges can increase the release of nickel ions from NITI orthodontic wire. This finding is important because it shows the potential for health risks associated with the use of NITI wire in the acidic environment. Further research is necessary to understand the mechanism of releasing nickel ions and its long-term effects on health.
