Summary
Simplified dental adhesives offer convenience but may compromise long-term bond durability. Material properties and preparation techniques significantly impact adhesion effectiveness for predictable restorative dentistry.
Area of Science:
- Dental materials science
- Restorative dentistry
- Biomaterials engineering
Background:
- Modern restorative dentistry emphasizes minimal-invasive techniques, relying heavily on effective enamel-dentine adhesives.
- Adhesive strategies include etch-and-rinse and self-etch approaches, with simplified one-step and two-step systems gaining popularity.
- Simplified adhesives often exhibit increased acidity and hydrophilicity, potentially leading to issues like water sorption and nanoleakage.
Purpose of the Study:
- To review the theoretical and clinical aspects of dental adhesion to enamel and dentine.
- To analyze the impact of simplified adhesive formulations on bond effectiveness and durability.
- To discuss strategies for overcoming challenges in achieving stable adhesion in restorative dentistry.
Main Methods:
- Literature review of current theoretical and clinical research on dental adhesives.
- Analysis of adhesive interaction with enamel and dentine substrates.
- Discussion of factors influencing bond stability, including material properties and preparation techniques.
Main Results:
- One-step adhesives, while user-friendly, can be more susceptible to degradation due to water sorption and nanoleakage.
- Durability of simplified adhesives is material-dependent and can be inferior to multi-step systems.
- Caries removal and cavity preparation techniques can alter the tooth substrate, potentially affecting adhesive performance.
Conclusions:
- Achieving stable adhesion requires consideration of both adhesive formulation and substrate characteristics.
- Material-dependent properties significantly influence the long-term clinical performance of dental adhesives.
- Further research and clinical strategies are needed to ensure predictable and durable restorative treatments.

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...
01:09Complexation Equilibria: Factors Influencing Stability of Complexes
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...
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...
02:32Bonding in Metals
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.
01:17Mortar Properties
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to the...
01:07Cohesion
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.
