Summary
Bond strength tests in dentistry do not consistently correlate with other in vitro phenomena like micro-leakage. Nanoleakage and interface characteristics may better predict dentin bond durability.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Adhesive Dentistry
Background:
- Dental adhesive materials are crucial for restorative procedures.
- Evaluating their performance requires understanding bond strength and other in vitro phenomena.
- A comprehensive review of the past 30 years of literature is needed.
Purpose of the Study:
- To review and outline the relationship between dental adhesive bond strength tests and other in vitro phenomena.
- To synthesize findings from the last three decades of research in this field.
Main Methods:
- A literature search was conducted using the PubMed database.
- Nearly 30 relevant articles published in dental literature were reviewed.
- Studies published in Japanese domestic journals were also included.
Main Results:
- Bond strength tests showed no consistent correlation with micro-leakage tests or gap formation at cavity margins.
- Nanoleakage tests and analysis of bonding interface morphology and chemistry showed potential for predicting dentin bond durability.
- Included studies spanned from approximately 1980 to the present.
Conclusions:
- Bond strength testing alone is not a reliable indicator of adhesive performance.
- Nanoleakage and interface characteristics offer more predictive value for long-term dentin bond durability.
- Development of advanced bond tests and in vitro phenomena analysis is necessary with material advancements.

02:40Chemical 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 (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

01:12Bonding 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...
02:49Bond 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.
02:13Bond Dissociation Energy and Activation Energy
Bond energy is the energy required to break a bond homolytically. These values are usually expressed in units of kcal/mol or kJ/mol and are referred to as bond dissociation energies when given for specific bonds or average bond energies when indicated for a given type of bond over many compounds. Firstly, the bond dissociation energy for a single bond is weaker than that of a double bond, which in turn is weaker than that of a triple bond. Secondly, hydrogen forms relatively strong bonds with...
