Release of Nickel Ions in Nickel-Titanium Orthodontic Wire: Comparison of Detergent and Non-Detergent Toothpaste

Introduction

Nickel-Titanium (NITI) orthodontic wire is a crucial component in orthodontic treatment, particularly in the early stages. This wire is renowned for its flexibility and ability to apply the right pressure on the teeth. However, one of the significant concerns associated with the use of NITI orthodontic wire is the potential release of nickel ions, which can pose health risks. Loose nickel ions can enter the body and have the potential to cause side effects such as carcinogenic, allergenic, mutagenic, and cytotoxic. This study aims to examine the difference in the release of nickel ions from the nickel-titani orthodontic wire after being soaked in two types of toothpaste, namely detergent and non-detergent toothpaste.

The Importance of Nickel-Titanium Orthodontic Wire

Nickel-Titanium (NITI) orthodontic wire is a popular choice among orthodontists due to its unique properties. It is flexible, yet strong, making it an ideal material for applying gentle yet consistent pressure on the teeth. This wire is also resistant to corrosion and can withstand the rigors of daily use. However, despite its many benefits, the use of NITI orthodontic wire has been linked to the release of nickel ions, which can have adverse effects on human health.

The Role of Toothpaste in the Release of Nickel Ions

Toothpaste plays a crucial role in the release of nickel ions from NITI orthodontic wire. The composition of toothpaste can affect the stability of the wire and influence the release of nickel ions. Detergent toothpaste, in particular, contains active ingredients that help clean teeth, but can also affect the stability of the wire. Non-detergent toothpaste, on the other hand, is usually softer and may have a lower potential to remove metal ions from the wire. This study aims to investigate the difference in the release of nickel ions from NITI orthodontic wire after being soaked in detergent and non-detergent toothpaste.

Research Methodology

This study uses a comparative laboratory experimental design. In this study, the sample of nickel-titani orthodontic wire with a diameter of 0.016 inches and a length of 2 cm is divided into two groups, each consisting of 20 samples. The first group is immersed in a detergent toothpaste, while the second group is soaked in a non-detergent toothpaste. These wires are soaked in 1.5 grams of toothpaste mixed with 29 ml of distilled water, and stored in an incubator at 37 ° C for 24 hours. After the immersion process, the wire is removed from the solution and analyzed using a * inductively coupled plasma mass spectrometer * (ICP) device to measure the amount of nickel ions that are released.

Research Results

The results of the analysis show that the average release of nickel ions from the wire soaked in detergent toothpaste is 0.203 ± 0.083 mg/L, while from non-detergent toothpaste is 0.231 ± 0.140 mg/L. Although there is a slight difference in the average value of the release of nickel ions between the two groups, the analysis using the Mann-Whitney test shows a significance value of 0.872 (p ≥ 0.05). This means that there is no significant difference in the number of nickel ions from nickel-titani (NITI) wires after being soaked in detergent toothpaste compared to non-detergent toothpaste.

Analysis and Explanation

The release of nickel ions from orthodontic wire can be influenced by various factors, including the pH of the solution, soaking time, and the composition of the toothpaste itself. Toothpaste containing detergent usually has active ingredients that help clean teeth, but can also affect the stability of orthodontic wire. Meanwhile, non-detergent toothpaste is usually softer and may have a lower potential to remove metal ions from the wire. However, the results showed that both detergent and non-detergent toothpaste did not have a significant effect on the release of nickel ions, so that both could be considered relatively safe in the context of the use of orthodontic wires.

Conclusion

This study provides valuable information on the release of nickel ions from NITI orthodontic wire after being soaked in detergent and non-detergent toothpaste. The results show that both types of toothpaste do not have a significant effect on the release of nickel ions, making them relatively safe for use in orthodontic treatment. However, it is essential for orthodontic practitioners and patients to consider the long-term effects of the use of nickel-sitanium wire, especially for patients who have sensitivity to nickel. This study adds an understanding of the relationship between the use of dental care products with oral health and orthodontic safety, as well as providing valuable information in the selection of appropriate toothpaste products for orthodontic patients.

Recommendations for Future Research

Further research can be done to explore other variables that might affect the release of nickel ions, in order to improve the safety and effectiveness of orthodontic care. Some potential areas of research include:

Investigating the effect of different types of toothpaste on the release of nickel ions
Examining the impact of soaking time on the release of nickel ions
Studying the effect of pH on the release of nickel ions
Investigating the role of other factors, such as temperature and humidity, on the release of nickel ions

By conducting further research in these areas, we can gain a better understanding of the factors that influence the release of nickel ions from NITI orthodontic wire and develop more effective strategies for minimizing the risks associated with its use.
