Summary
Coca-Cola significantly increased nickel ion release from orthodontic appliances, while orange juice showed no such effect. This study highlights beverage impacts on dental device metal ion release.
Area of Science:
- Biomaterials Science
- Dental Materials
- Analytical Chemistry
Background:
- Fixed orthodontic appliances are susceptible to ion release.
- Dietary factors may influence metal ion release from these devices.
Purpose of the Study:
- To investigate the effect of orange juice and Coca-Cola on metal ion release from orthodontic appliances.
- To quantify ion release patterns under simulated oral conditions.
Main Methods:
- Utilized a continuous flow in vitro system for testing orthodontic appliances.
- Analyzed collected samples using multielemental Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES).
Main Results:
- Coca-Cola consumption led to a notable increase in Nickel (Ni) ion release.
- Calculated ion release (μg) into Coca-Cola and orange juice respectively included: Ni (37.75; 15.33), Fe (≥156.1; 48.42), Mn (41.16; 9.164), Mo (30.12; 9.999), Cd (2.173; 0.5967), Cr (1.052; 3.604), and Cu (32.91; 57.87).
Conclusions:
- Orange juice did not intensify metal ion release from orthodontic appliances.
- Coca-Cola significantly increased the release of nickel ions from orthodontic appliances.

25.7K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

00:43Complexometric Titration: Ligands
2.7K
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...

01:26EDTA: Auxiliary Complexing Reagents
1.6K
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

01:19Masking and Demasking Agents
4.0K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

01:19Complexation Equilibria: The Chelate Effect
1.6K
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

01:09Complexation Equilibria: Factors Influencing Stability of Complexes
985
In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...
