Bonding and Strength of Aggregate01:12

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

Chemical Bonds


Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons from...
The Equilibrium Binding Constant and Binding Strength02:18

The Equilibrium Binding Constant and Binding Strength

The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Bond Energies and Bond Lengths02:49

Bond Energies and Bond Lengths

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.
Drug-Receptor Bonds01:25

Drug-Receptor Bonds

Drug-receptor bonds are formed through various chemical forces when drugs interact with target cells. Covalent bonds, strong and irreversible, are exemplified by DNA-alkylating anticancer agents that inhibit cell division. However, such irreversible drug binding lacks selectivity and can modify the DNA of the surrounding healthy cells. Covalent binding often contributes to tissue toxicity, as seen with chloroform and paracetamol metabolites binding to the liver, causing hepatotoxicity.

Area of Science:

  • Dental Materials Science
  • Clinical Dentistry
  • Biomaterials Research

Background:

  • Laboratory bond-strength testing is widely used to evaluate dental adhesives.
  • Concerns exist regarding the predictability of laboratory bond strength for clinical effectiveness.
  • Variability in reported bond strength values suggests a lack of standardized testing protocols.

Purpose of the Study:

  • To conduct an extensive literature review on laboratory bond-strength testing methods for dental adhesives.
  • To perform a second extensive literature review on clinical effectiveness data, specifically retention rates of Class-V restorations.
  • To investigate the potential relationship between laboratory bond-strength data and clinical outcomes of dental adhesives.

Main Methods:

  • Systematic literature review of laboratory bond-strength testing methodologies.
  • Systematic literature review of clinical studies reporting retention rates for adhesive Class-V restorations.
  • Comparative analysis to correlate bond-strength data with clinical effectiveness.

Main Results:

  • Identified significant variability in bond-strength results across different research institutions.
  • Documented diverse methodologies employed in laboratory bond-strength testing.
  • Observed a lack of direct correlation in the reviewed literature between specific bond-strength values and long-term clinical retention rates.

Conclusions:

  • The current lack of standardized laboratory bond-strength testing protocols contributes to inconsistent results.
  • Predicting clinical effectiveness of dental adhesives solely based on laboratory bond-strength data remains challenging.
  • Further research is needed to establish reliable correlations between in vitro testing and in vivo performance.
