Summary
Repeated bracket bonding does not significantly alter tooth enamel color compared to intact enamel or single bonding. This study found no negative influence on enamel color change after in vitro coloration.
Area of Science:
- Dental Materials Science
- Orthodontic Research
- Enamel Color Stability
Background:
- Orthodontic treatment involves bracket bonding, which may affect tooth enamel color.
- Understanding the impact of repeated bracket bonding on enamel aesthetics is crucial for patient satisfaction.
Purpose of the Study:
- To evaluate the effect of repeated bracket bonding on tooth enamel color changes.
- To compare color alterations in enamel subjected to repeated bonding versus intact or single-bonded surfaces after in vitro coloration and photoaging.
Main Methods:
- Eighty-one premolars were divided into three groups: intact enamel, single bracket bonding, and triple bracket bonding.
- Samples underwent three cycles of immersion in staining solutions and photoaging.
- Enamel color changes (ΔE) were measured using a spectrophotometer before and after procedures.
Main Results:
- All groups exhibited significant color changes within themselves (P < 0.05).
- However, the differences in color change between the groups (intact, single bonding, repeated bonding) were not statistically significant (P > 0.05).
Conclusions:
- Repeated bracket bonding does not negatively impact enamel color change.
- Enamel color stability is comparable between intact, single-bonded, and repeatedly bonded surfaces following in vitro coloration.

Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

02:49Bond Energies and Bond Lengths
31.5K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

02:43Peptide Bonds
83.2K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
